The illustrated volume of the cylinder is 769cm³.

One of the most fundamental curvilinear geometric shapes, a cylinder has traditionally been a three-dimensional solid. It is regarded as a prism with a circle as its base in basic geometry. In many contemporary branches of geometry and topology, a cylinder can also be defined as an infinite curvilinear surface.

It should be noted that the formula for finding the volume of a cylinder is πr²h

where π = 3.14

r = radius

h = height

Let's assume that the height is 5cm and radius is 7cm. The volume will be:

V = πr²h

Volume = 3.14 × 7² × 5

Volume = 769cm³

To find the total mass of all the worker bees in the hive, you need to multiply the mass of a single worker bee by the number of worker bees in the hive.

The mass of a single worker bee is 2 x 10^-4 kilograms, and there are 8 x 10^4 worker bees in the hive.

So the total mass of all the worker bees in the hive is (2 x 10^-4 kilograms) * (8 x 10^4 worker bees) = 0.16 kilograms.

In standard form, this is written as 1.6 x 10^-1 kilograms.

Function 1: slope is 2

Function 2: (-5 + 4)/(2-1)= -1/1= -1

A function f such that f '(x) = 3x^3 and the line 81x + y = 0 is tangent to the graph of f is f(x) = 3x^4/4 + 729/4.

In the given question, we have to find a function f such that f'(x) = 3x^3 and the line 81x + y = 0 is tangent to the graph of f.

The given function is f'(x) = 3x^3.

No integrating on both side,

f(x) = [tex]\int3x^3dx[/tex] + C

f(x) = 3x^4/4 + C

As given, the line 81x + y = 0 is tangent to the graph of f.

So, slope at point of tangent; f'(x) = -81

So, 3x^3 = -81

Divide by 3 on both side, we get

x^3 = -27

Taking cube root on both side, we get

x = -3

So putting the value of x in 81x + y = 0, we get

y = 243

Thus, f(x) passes through (-3, 243).

So, 243 = 3/4(81) + C

Multiply by 4 on both side, we get

972 = 243 + 4C

Subtract 243 on both side, we get

4C = 729

Divide by 4 on both side, we get

C = 729/4

So, f(x) = 3x^4/4 + 729/4

Answer:

Read carefully below

Step-by-step explanation:

In general, the inverse of a function f(x) is a function g(x) such that f(g(x)) = g(f(x)) = x for all values of x in the domain of f(x) and g(x). To find the inverse of a function, we need to switch the input and output variables and solve for the new output variable.

In this case, we are given the function -2f(x+5)-4. To find the inverse of this function, we need to switch the input and output variables and solve for the new output variable, which we will call y. We can do this by first moving all the terms to one side of the equation, and then solving for y:

-2f(x+5) - 4 = y

-2f(x+5) = y + 4

f(x+5) = (y + 4) / -2

This is the inverse function of -2f(x+5)-4. However, keep in mind that not all functions have inverses. In particular, a function must have the property that it is one-to-one (i.e. it maps unique inputs to unique outputs) in order to have an inverse. It is not clear from the given information whether the function -2f(x+5)-4 is one-to-one, so it is possible that it does not have an inverse.

Divide by 12 to go from the APR to the monthly interest rate

(9.5%)/12 = 0.7916667%

The decimal form is 0.007916667 approximately.

Multiply this with the starting balance $1367.90 and we get:

0.007916667*1367.90 = 10.8292 which rounds to 10.83

The interest payment for the 1st month is $10.83; which means the principal payment would be 400-10.83 = 389.17

This principal payment will then drop the balance from $1367.90 to 1367.90-389.17 = 978.73 dollars.

The value $978.73 is now the starting balance of the 2nd month. This process of...

is repeated until the balance is $0.

This is what the table would look like

[tex]\begin{array}{|c|c|c|c|c|c|} \cline{1-6}\text{Month} & \text{Starting} & \text{Interest} & \text{Principal} & \text{Payment} & \text{Ending }\\& \text{Balance} & & & & \text{Balance}\\\cline{1-6}1 & 1367.9 & 10.83 & 389.17 & 400 & 978.73\\\cline{1-6}2 & 978.73 & 7.75 & 392.25 & 400 & 586.48\\\cline{1-6}3 & 586.48 & 4.64 & 395.36 & 400 & 191.12\\\cline{1-6}4 & 191.12 & 1.51 & 191.12 & 192.63 & 0\\\cline{1-6}\end{array}[/tex]

Many credit card companies and banks offer free calculators on their website, or you can find similar free calculators online elsewhere, that will quickly calculate a table like shown above. It is called an amortization table or amortization schedule.

With the exception of the 4th month, each row has the principal and interest add to the $400 monthly payment. The last row will have a payment of 1.51+191.12 = 192.63 dollars.

The total amount paid back would be 400+400+400+192.63 = 1392.63 dollars. This is the sum of the values in the "payment" column.

-------------------------------------------------------------------------

Here's another way to determine the answer.

The monthly payment formula is

[tex]\displaystyle P = \frac{Li}{1 - (1+i)^{-n}}[/tex]

where,

In this case,

Let's solve for the variable n. We'll need logarithms to isolate the exponent.

Part 1

[tex]\displaystyle P = \frac{Li}{1 - (1+i)^{-n}}\\\\\\\displaystyle 400 = \frac{1367.90*0.007916667}{1 - (1+0.007916667)^{-n}}\\\\\\\displaystyle 400 = \frac{10.8292087893}{1 - (1.007916667)^{-n}}\\\\\\\displaystyle 400(1 - (1.007916667)^{-n}) = 10.8292087893\\\\\\[/tex]

Part 2

[tex]\displaystyle 1 - (1.007916667)^{-n} = 10.8292087893/400\\\\\\\displaystyle 1 - (1.007916667)^{-n} = 0.0270730\\\\\\\displaystyle -(1.007916667)^{-n} = 0.0270730-1\\\\\\\displaystyle -(1.007916667)^{-n} = -0.9729270\\\\\\\displaystyle (1.007916667)^{-n} = 0.9729270\\\\\\[/tex]

Part 3

[tex]\displaystyle \log((1.007916667)^{-n}) = \log(0.9729270)\\\\\\\displaystyle -n*\log(1.007916667) = \log(0.9729270)\\\\\\\displaystyle n = -\log(0.9729270)/\log(1.007916667)\\\\\\\displaystyle n = 3.4805965\\\\\\[/tex]

Each decimal value is approximate.

That value of n then rounds up to the nearest integer n = 4

We do not round to n = 3 since that would be one month short, as shown in the table above.

You can use a graphing calculator to quickly solve that equation for the variable n. It can be used as a way to visually confirm the answer.

The point where the tangent to the given equation is horizontal is [tex](x, y) = (-2, -5)[/tex].

To find the tangent of a curve, we have to find the first derivative of the function. Hence, the tangent of the given curve is given by

⇒ [tex]f'(x) = \frac{d{f(x)}}{dx} = \frac{d{x^{2}}}{dx} + \frac{d(4x)}{dx} - \frac{d(1)}{dx}[/tex]

⇒ [tex]f'(x) = 2x + 4[/tex]

Now, as the tangent is horizontal, that means the slope of the tangent is 0, hence setting [tex]f'(x) = 0[/tex] , we get the equation

⇒ [tex]f'(x) = 2x + 4 = 0[/tex]

Solving the equation obtained for the variable x,

⇒ [tex]2x = -4\\[/tex]

⇒ [tex]x = -2[/tex]

Now, putting the obtained value for x in the original equation, we get

⇒ [tex]f(x) = (-2)^{2} + 4(-2) - 1\\[/tex]

⇒ [tex]f(x) = -5[/tex]

Hence, the point where the tangent to the given equation is horizontal is [tex](x, y) = (-2, -5)[/tex].

[tex]14.5 - 1.5 < = x[/tex]

This inequality can be read as "14.5 minus 1.5 is less than or equal to the amount of gas you have left in your tank, x."

Solving for x, we get:

So the amount of gas you have left in your tank is greater than or equal to 13 gallons.

Answer:

m = -21.

Step-by-step explanation:

To solve this equation, we can use the distributive property to expand the left side and the right side of the equation:

19(2m - 16) = 13(2m + 4)

38m - 304 = 26m + 52

Then we can combine like terms on both sides of the equation to obtain:

38m - 26m = 52 - 304

12m = -252

Finally, we can divide both sides of the equation by 12 to find the value of m:

12m / 12 = -252 / 12

m = -21

Therefore, the value of m that satisfies the equation is m = -21.

Answer:

To find the sum of 2/3 + (-1)/3, you can first convert the fraction to an equivalent fraction with a common denominator. In this case, the common denominator would be 3. 2/3 can be written as 2 x (3/3) = 2/3 and -1/3 can be written as -1 x (3/3) = -1/3. Then, you can add the numerators and the denominator will remain the same. So, the sum of 2/3 + (-1)/3 is 1/3.

The equivalent expression to {(2 3/10)⁴ ÷ (9/10)⁵}⁴ is "2 and three tenths raised to the sixteenth power divided by nine tenths raised to the twentieth power".

s=h+42  ==> there were 42 more sells for soda than compared to hot dog

h+42+h=250  ==> plugin h+42 for s

h+h+42=250 ==> simplify

2h+42=250 ==> solve for h

2h+42-42=250-42 ==> isolate h by subtracting 42 on both sides

2h = 208

y = 3

yes, that's it for this here too.

it means that any value for x is valid, and all have the assigned y value 3.

6.

remember, the usual equation for a line is

y = ax + b

"a" being the slope, "b" the y-intercept (the y-value when x = 0).

we see the y-value for x = 0 is 3. that is "b".

for the slope we need 2 points and calculate the x- and y- coordinate differences.

always look for points with integer coordinates.

I see e.g. (0, 3) and (3, 2).

x changes by +3 (from 0 to 3).

y charges by -1 (from 3 to 2).

the slope "a" = -1/+3 = -1/3

the equation is then

y = (-1/3)x + 3

7.

we do exactly the same things.

we see the y-value for x = 0 is +1. that is "b".

I see e.g. these points : (0, 1) and (3, 2).

x changes by +3 (from 0 to 3).

y changes by +1 (from 1 to 2).

the slope "a" is +1/+3 = 1/3.

the equation is

y = (1/3)x + 1

8.

and again the same things.

we see the y-value for x = 0 is +3. that is "b".

I see e.g. these points : (0, 3) and (-3, 0).

x changes by -3 (from 0 to -3).

y changes by -3 (from 3 to 0).

the slope "a" is -3/-3 = 3/3 = 1.

the equation is

y = x + 3

Answer:

Step-by-step explanation: y+9=-3(x-4)......given equation

This equation can be expanded further and simplified

Answer:

To find the area of a triangle, we can use the formula:

Area = (base * height) / 2

To find the area of triangle ABC, we first need to find the base and the height.

Since angle B is 75 degrees, we can use the fact that the sum of the angles in a triangle is 180 degrees to find the measure of angle A: 180 - 75 - 90 = 15 degrees.

Then, we can use the fact that the measure of an angle in a triangle is proportional to the length of the side opposite that angle to find the length of side AC:

AC/AB = m∠A/m∠B

AC = (m∠A/m∠B) * AB

Substituting, we get:

AC = (15/75) * 12 = 3

Now that we know the base and the height of the triangle, we can use the formula to find the area:

Area = (3 * 12) / 2 = 18

Therefore, the area of triangle ABC is 18 square cm.

The measurement of angles △XYZ are ∠X = 59°, ∠Y = 89°, and ∠Z = 32°.

The measurement of angles △LMN are ∠L = 59°, ∠M = 89°, and ∠N = 32°.

What is angle?

An angle is a figure in Euclidean geometry made up of two rays that share a common terminal and are referred to as the angle's sides and vertices, respectively. Angles created by two rays are in the plane where the rays are located. The meeting of two planes also creates angles. We refer to these as dihedral angles.

Given that, △XYZ and △LMN are similar triangle.

Since the triangles are similar, thus the measurement of triangles are similar.

Therefore,

∠X = ∠L, ∠Y = ∠M, ∠Z = ∠N.

∠Y = ∠M = 89° and ∠Z = ∠N = 32°.

The sum of all interior angles of triangle is 180°.

∠X + ∠Y + ∠Z = 180°

∠X + 89° + 32° = 180°

∠X + 121° = 180°

Subtract 121° from both sides:

∠X  = 59°

∠X = ∠L = 59°.
