Fierro brothers, a discount broker, charges their customers a $19 flat fee per trade. The sondo investment house charges a 2% commission. For what amount of stock would both brokers charge the same commission?
Answer:
yes it will be the same
Step-by-step explanation:
Let’s call the amount of stock traded “x”. Then we can set up an equation like this:
$19 = 0.02x
To solve for x, we can divide both sides by 0.02:
$950 = x
Therefore, if you trade $950 worth of stock, both Fierro Brothers and Sondo Investment House would charge you the same commission.
The length of a rectangle is
double its width and the area of
the rectangle is 288 cm². What is
the perimeter of the rectangle?
The perimeter of the rectangle is 72 cm.
what you mean by perimeter?Perimeter is the total distance around the boundary of a two-dimensional shape. It is the sum of the lengths of all sides or edges of the shape.
The perimeter is usually measured in units such as centimeters (cm), meters (m), feet (ft), or inches (in), depending on the unit of measurement used for the sides or edges.
Let's start by assigning variables to the length and width of the rectangle.
Let x be the width of the rectangle in cm.
Then, the length of the rectangle is double the width, which is 2x cm.
We know that the area of the rectangle is 288 cm², so we can set up an equation:
Area = Length x Width
288 = 2x * x
Simplifying the equation, we get:
288 = 2x²
Dividing both sides by 2, we get:
144 = x²
Taking the square root of both sides, we get:
x = ± 12
Since x cannot be negative (as it represents a length), we take x = 12 cm as the width of the rectangle.
The length of the rectangle is 2x, which is 24 cm.
Now we can find the perimeter of the rectangle, which is given by the formula:
Perimeter = 2(Length + Width)
Substituting the values we found, we get:
Perimeter = 2(24 + 12) = 72 cm
Therefore, the perimeter of the rectangle is 72 cm.

The sunfish gains
2
7
7
2
start fraction, 2, divided by, 7, end fraction of its mass every
days.
Step-by-step explanation:
We can use the formula for exponential growth to find the rate at which the sunfish gains mass:
M(t) = M(0) * e^(kt)
where:
M(0) = the initial mass of the sunfish (which we don't know)
k = the growth rate constant (which we also don't know yet)
t = the elapsed time since the sunfish was born (in days)
e = the mathematical constant approximately equal to 2.71828...
We are given the formula for M(t), which is:
M(t) = 4 * (81/49)^t
This means that M(0) = 4 * (81/49)^0 = 4.
To find the growth rate constant k, we can use the fact that the sunfish gains 2/7 of its mass every day. This means that the daily growth rate is 2/7 of the current mass. In other words, the daily growth rate is:
(2/7) * M(t)
We can relate this to the exponential growth formula by taking the derivative of M(t) with respect to t:
dM/dt = k * M(t)
Taking the derivative of M(t), we get:
dM/dt = ln(81/49) * 4 * (81/49)^t
Setting this equal to the daily growth rate, we get:
(2/7) * M(t) = ln(81/49) * 4 * (81/49)^t
Simplifying this expression, we get:
k = ln(81/49) * 4/7
Using a calculator, we can evaluate this expression to get:
k ≈ 0.0919
Therefore, the rate at which the sunfish gains mass is given by:
dM/dt = 0.0919 * M(t)
To find out how much mass the sunfish gains in one day, we can substitute M(t) = 4 * (81/49)^t into this formula and evaluate it at t = 1 (since we want to know the daily rate of change):
dM/dt = 0.0919 * 4 * (81/49)^1
dM/dt ≈ 0.54
This means that the sunfish gains 0.54 milligrams every day. To express this as a fraction of its mass, we can divide by the current mass:
(0.54/4) ≈ 0.1375
So the sunfish gains approximately 2/7 (or 0.2857) of its mass every 2.08 (or 7/2.54) days. Rounded to two decimal places, this is 0.14 or approximately 2/7 of its mass every 2.08 days.

Find a center of mass of a thin plate of density delta = 6 bounded by the lines y = x and x = 0 and the parabola y = 20 - x^2 in the first quadrant. X = y = (Type simplified fractions. )
The center of mass of the thin plate of density delta = 6 bounded by the lines y = x and x = 0 and the parabola is located at (x, y) = (4/15, 1/15).
To find the center of mass of a thin plate,
Calculate the moments and products of inertia with respect to the x and y axes,
And then use them to find the coordinates of the center of mass.
First, determine the limits of integration.
Since the plate is bounded by the lines y=x and x=0 and the parabola y=20-x² in the first quadrant,
Integrate over the following limits.
0 ≤ x ≤ 4, and
x ≤ y ≤ 20 - x²
The mass of the plate can be found by integrating the density delta = 6 over the plate.
m = ∫∫over R δ dA
= ∫∫over R 6 dA
where R is the region bounded by the given curves.
m =[tex]\int_{0}^{4}[/tex] ∫x²⁰⁻ˣ² 6 dy dx
Simplifying the limits, we get,
m = ∫0⁴ 6x(20-x²) dx
Evaluating this integral gives,
m = 960
Next, find the moments and products of inertia.
The moments of inertia are given by,
Ix = ∫∫over R y² δ dA, and
Iy = ∫∫over R x² δ dA
The product of inertia is given by,
Ixy = ∫∫ over R xy δ dA
Substituting the given density delta = 6 and integrating over the region R, we get,
Ix = [tex]\int_{0}^{4}[/tex] ∫x²⁰⁻ˣ² y² 6 dy dx
= 64/3
Iy = [tex]\int_{0}^{4}[/tex] ∫x²⁰⁻ˣ² x² 6 dy dx
= 512/15
Ixy = [tex]\int_{0}^{4}[/tex] ∫x²⁰⁻ˣ² xy 6 dy dx
= 64/3
Using these moments and products of inertia,
The coordinates of the center of mass (X, Y) can be found using the following formulas.
X = Iy / m, and
Y= Iy / m
Substituting the values we have calculated, we get,
X = (512/15) / 960
= 4/15
Y = (64/3) / 960
= 1/15
Therefore, the center of mass of the thin plate is located at (x, y) = (4/15, 1/15).

at how many points on the interval is the line tangent to parallel to the secant line connecting the function endpoints?
The line tangent to f(x) = x + sin(x) is parallel to the secant line connecting the endpoints at x = π on the interval [-2π, 2π].
Let's begin by finding the slope of the secant line connecting the endpoints of the function. The endpoints of the function on the interval [-2π, 2π] are (-2π, -2π + sin(-2π)) and (2π, 2π + sin(2π)), which evaluate to (-2π, 0) and (2π, 0), respectively.
The slope of the secant line is
m = (0 - 0)/(2π - (-2π)) = 0
Since we want the tangent line to be parallel to the secant line, the slope of the tangent line should also be 0. We can find the equation of the tangent line using the point-slope form
y - (x + sin(x)) = 0
y = x + sin(x)
To find the points on the interval where the tangent line is parallel to the secant line, we need to find the values of x where the derivative of f(x) is equal to 0 (i.e., where the slope of the tangent line is 0). The derivative of f(x) is
f'(x) = 1 + cos(x)
Setting this equal to 0 and solving for x, we get
cos(x) = -1

Solid A and solid B are similar.
The ratio of the volume of solid A to the volume of solid B is 27:1000
The surface area of solid A is 810 cm²
Calculate the surface area of solid B.
The surface area of solid B is 9000 cm².
What is ratio?
A ratio is a comparison of two quantities or values, often expressed as a fraction. Ratios can be used to express the relationship between two or more quantities.
Since solids A and B are similar, their corresponding linear dimensions are proportional. Let the scale factor be k, such that the dimensions of solid A are k times larger than the corresponding dimensions of solid B.
The ratio of their volumes is given as 27:1000. Therefore:
(volume of A) / (volume of B) = 27/1000
Let the volume of solid B be V. Then the volume of solid A is (27/1000)V.
Since the surface area of a solid is proportional to the square of its linear dimensions, we have:
[tex]$\frac{surface\ area\ of\ A}{surface\ area\ of\ B} = \frac{k_{A}^{2}}{k_{B}^{2}}$[/tex]
where kA and kB are the linear dimensions of solids A and B respectively.
Since the solids are similar, we can write:
[tex]$k_{A} / k_{B} = \frac{(volume\ of\ A)^{\frac{1}{3}}}{(volume\ of\ B)^{\frac{1}{3}}}$[/tex]
kA / kB = (volume of A)^(1/3) / (volume of B)^(1/3)
Substituting the given volume ratio and solving for kA / kB, we get:
[tex]$k_A/k_B = \left(\frac{27}{1000}\right)^{1/3} = 0.3$[/tex][tex]$k_A/k_B = \left(\frac{27}{1000}\right)^{1/3} = 0.3$[/tex]
Therefore, kA = 0.3 kB.
Now we can substitute the given surface area of solid A and solve for the surface area of solid B:
(surface area of A) / (surface area of B) = (kA)² / (kB)²
810 / (surface area of B) = 0.3²
(surface area of B) = 810 / 0.09
(surface area of B) = 9000 cm²
Therefore, the surface area of solid B is 9000 cm².

To landscape his 70 ft by 60 ft backyard, Austin is planning first to put down a 4 inch layer of topsoil. He can buy bags of topsoil at $2.50 per 3-ft3 bag, with free delivery. Or he
can buy bulk topsoil for $22.00/yd, plus a $20 delivery fee. Which option is less expensive?
Buying bulk topsoil is less expensive than buying bags of topsoil in this case.
Describe Volume?Volume is a measure of the amount of space occupied by a three-dimensional object. It is typically measured in cubic units, such as cubic meters (m³), cubic centimeters (cm³), or cubic feet (ft³).
To find the volume of a simple object such as a cube, rectangular prism, or cylinder, you can use a formula that involves multiplying the length, width, and height of the object. For example, the formula for the volume of a rectangular prism is V = lwh, where V is the volume, l is the length, w is the width, and h is the height.
For more complex objects, such as irregular shapes or those with curved surfaces, you can use techniques such as integration or approximation to find the volume.
First, we need to determine how many cubic feet of topsoil Austin needs to cover his backyard with a 4 inch layer. We can start by calculating the volume of his backyard in cubic feet:
Volume = length x width x depth
Volume = 70 ft x 60 ft x (4 in / 12) ft
Volume = 1400 ft³
So Austin needs 1400 cubic feet of topsoil to cover his backyard with a 4 inch layer.
Option 1: Bags of Topsoil
Each bag of topsoil covers 3 cubic feet, so Austin needs 1400 / 3 = 466.67 bags of topsoil. Since he can only buy whole bags, he will need to buy 467 bags. Each bag costs $2.50, so the total cost of the topsoil would be:
Total cost = number of bags x cost per bag
Total cost = 467 x $2.50
Total cost = $1167.50
Since delivery is free, the total cost of the topsoil is $1167.50.
Option 2: Bulk Topsoil
Bulk topsoil costs $22.00 per cubic yard, and Austin needs 1400 / 27 = 51.85 cubic yards. Since he can only buy whole yards, he will need to buy 52 yards. The cost of the topsoil itself would be:
Cost of topsoil = volume of topsoil x cost per cubic yard
Cost of topsoil = 52 yd³ x $22.00/yd³
Cost of topsoil = $1144.00
There is also a $20 delivery fee, so the total cost of the topsoil would be:
Total cost = cost of topsoil + delivery fee
Total cost = $1144.00 + $20.00
Total cost = $1164.00
Therefore, buying bulk topsoil is less expensive than buying bags of topsoil in this case.

(d) if the insurance company charges $3 million for 84 months of insurance, how much profit does the company expect to make (in dollars)? (round your answer to the nearest dollar.) $(no response) incorrect: your answer is incorrect.
The satellite should be insured for 98 months (rounded up to the nearest month) to be 96% confident that the microchip will last beyond the insurance date.
To answer this question, we need to find the number of months for which we can be 96% confident that the microchip will not malfunction. This means we want to find the value of x such that P(X > x) = 0.04, where X is the random variable representing the life expectancy of the microchip.
We know that X follows a normal distribution with mean μ = 92 months and standard deviation σ = 3.6 months. Therefore, we can standardize X to the standard normal distribution Z ~ N(0, 1) using the formula
Z = (X - μ) / σ
We can then rewrite the probability P(X > x) as
P(X > x) = P(Z > (x - μ) / σ)
1.75 = (x - 92) / 3.6
Solving for x, we get
x = 98 months

through ten games of basketball this season, jevonte has made 7 out of 8 of his free-throws. which word or phrase describes the probability that jevonte will hit his next free throw?
The probability that Jevonte will hit his next free throw is "likely" or "high".
Since Jevonte has made 7 out of 8 of his free throws so far, he has a success rate of 87.5%, which is quite high. Therefore, it is reasonable to expect that he will continue to make his free throws at a similar rate, making it likely that he will hit his next free throw.
what is probability?
Probability is a measure of the likelihood of an event occurring. It is a number between 0 and 1, where 0 means the event is impossible and 1 means the event is certain. A probability of 0.5 (or 50%) means the event is just as likely to occur as it is not to occur. Probability is used extensively in fields such as mathematics, statistics, physics, engineering, economics, and many other areas to model and analyze uncertain events or situations.

The length of the diagonal from L to N is approximately 60.8, and the length of the diagonal from M to O is approximately 47.0.
How to determine the lengths of the diagonals of rectangle LMNOTo find the lengths of the diagonals of rectangle LMNO, we first need to find the length of MN and LO.
Since LMNO is a rectangle, we know that opposite sides are congruent, so LN = MO and LO = MN.
Given that LN = 4x - 17 and MO = 2x + 13, we can set them equal to each other and solve for x:
4x - 17 = 2x + 13
2x = 30
x = 15
Now that we know x, we can find LN and MO:
LN = 4x - 17 = 4(15) - 17 = 43
MO = 2x + 13 = 2(15) + 13 = 43
Therefore, MN = LO = 43.
To find the length of the diagonals, we can use the Pythagorean theorem. Let's call the diagonal from L to N d1, and the diagonal from M to O d2:
d1^2 = LM^2 + LN^2
d1^2 = MN^2 + LN^2
d1^2 = 43^2 + 43^2
d1^2 = 3698
d1 ≈ 60.8
d2^2 = MO^2 + LM^2
d2^2 = MN^2 + LM^2
d2^2 = 43^2 + 18^2
d2^2 = 2209
d2 ≈ 47.0
Therefore, the length of the diagonal from L to N is approximately 60.8, and the length of the diagonal from M to O is approximately 47.0.
