An equivalent fraction to 5/16 is
a. 5/32
b. 10/32
c.1/2
d. 10/16
Answer:
B is the answer..................
==================================================
Explanation:
Multiply top and bottom of the original fraction by 2
[tex]\frac{5}{16} = \frac{5*2}{16*2} = \frac{10}{32}[/tex]
Or you could go in reverse to divide each part of 10/32 by the GCF 2
[tex]\frac{10}{32} = \frac{10\div 2}{32\div 2} = \frac{5}{16}[/tex]
-------------------
Another alternative is to use your calculator to find the decimal version of each answer choice
5/32 = 0.15625
10/32 = 0.3125
1/2 = 0.5
10/16 = 0.625
And compare these results with 5/16 = 0.3125
Both 5/16 and 10/32 have the same decimal value 0.3125, which makes them equal.

Resolve the vector into components. 1. A vector starting at the point Q = (4, 6) and ending at the point P = (1, 2).
2. A vector starting at the point P = (1, 2) and ending at the point Q = (4, 6).
Answer:
1. Horizontal component = -3 units
Vertical component = -4 units
2. Horizontal component = 3 units
Vertical component = 4 units
Step-by-step explanation:
If a vector M, starting at point A = (a, b) and ending at point B = (c, d) is given, then the vector can be resolved into x and y components as follows;
M = AB
Where;
AB = B - A
AB = (a, b) - (c, d)
AB = (a-c, b-d)
AB = (a-c)i + (b-d)k
Therefore, a-c and b-d are the x and y components of the vector M.
(1) Let the vector be M:
Starting point of M = Q = (4, 6)
Ending point of M = P = (1, 2)
So,
M = PQ
Where;
PQ = Q - P
PQ = (1,2) - (4,6)
PQ = (1-4, 2-6)
PQ = (-3, -4)
Therefore,
M = PQ = -3i - 4j
The x and y components of M are therefore, -3 and -4 respectively.
(2) Let the vector be M:
Starting point of M = P = (1, 2)
Ending point of M = Q = (4, 6)
So,
M = PQ
Where;
PQ = Q - P
PQ = (4,6) - (1,2)
PQ = (4-1, 6-2)
PQ = (3, 4)
Therefore,
M = PQ = 3i + 4j
The x and y components of M are therefore, 3 and 4 respectively.
Note: The x and y components are also called the horizontal and vertical components respectively.

The ______ of a function is the complete set of inputs, whereas the _______ is the set of all outputs
Answer:
Domain, range
Step-by-step explanation:
The domain of a function is the complete set of inputs, whereas the range is the set of all outputs.
Domain= Input
Range= Output
The domain of a function is the complete set of inputs, whereas the range is the set of all outputs.
What are the domain and range of the function?The domain of the function includes all possible x-values of a function, and the range includes all possible y-values of the function.
The domain of a function refers to all the possible input values that can be plugged into a function and produce a valid output. It represents all the values that are allowed as inputs to the function.
The range of a function refers to all the possible output values that can be produced by the function. It represents the set of all values that the function can produce as outputs, given the inputs from the domain.
So, the domain represents the set of all possible inputs to the function, and the range represents the set of all possible outputs of the function.

(Plzzz someone help with this)
Answer:
Step-by-step explanation:
A). Yes. If we rotate shape I by 90° clockwise about the origin shape I will overlap shape II.
Coordinates of one point of figure I are A(-1, 3).
After rotation 90° clockwise,
(x, y) → (y, -x)
Following this rule,
A(-1, 3) → A'(3, 1)
It clearly states that figure I will overlap figure II.
B). No. because length of the quadrilateral I is different from the length of the quadrilateral given in figure III while width are same.
Both are different quadrilaterals.
C). Yes. If the figure I is reflected over x-axis, we get figure III.
D). Yes. By the translation of figure I by 3 units right and 4 units down we get image figure V.
Rule followed for the translation,
(x, y) → (x+3, y-4)

Answer: B) Profit per shirt goes from $10 to $15
================================================
Explanation:
Focus on the two points (2,0) and (3,10). The slope of the line through these points is
m = (y2-y1)/(x2-x1)
m = (10-0)/(3-2)
m = 10
Meaning the profit per shirt for this line is $10 per shirt.
----------
Now move onto the other line. Focus on the points (9,40) and (11,70)
m = (y2-y1)/(x2-x1)
m = (70-40)/(11-9)
m = 15
The profit per shirt has gone up to $15 per shirt

A student dropped a textbook from the top floor of his dorm and it fell according to the formula s(t) = −16t 2 + 8√t , where t is the time in seconds and s(t) is the distance in feet from the top of the building.What was the average speed of the fall? Use the fact that the pencil hit the ground in exactly 2.8 seconds. Round your answer to 2 decimal places.
Answer:
-29.61m/sStep-by-step explanation:
Given the distance of fall of the student in term of the time t expressed by the equation s(t) = −16t² + 8√t, to get the average speed of fall of the pencil after 2.8 secs, we will need to differentiate the given function first since Velocity is the change in distance of a body with respect to time i.e
V = d(s(t))/dt
s(t) = −16t² + 8t^1/2
V = -32t+1/2(8)t^(1/2 - 1)
V = -32t+4t^-1/2
The average speed of the fall Using the fact that the pencil hit the ground in exactly 2.8 seconds, will be gotten by substituting t = 2.8 into the resulting equation.
V = -32t+4(2.8)^-1/2
V = -32t+4/√2.8
V = -32+4/1.6733
V = -32+2.391
v = -29.61m/s
Hence the average speed of the fall is -29.61m/s
The average speed of the fall is -29.61m/s
Calculation of the average speed:[tex]V = d(s(t))\div dt\\\\s(t) = −16t^2 + 8t^{1/2}\\\\V = -32t+1/2(8)t^{(1/2 - 1)}\\\\V = -32t+4t^{-1/2}[/tex]
Now here t = 2.8 seconds
So,
[tex]V = d(s(t))\div dt\\\\s(t) = −16t^2 + 8t^{1/2}\\\\V = -32t+1/2(8)t^{(1/2 - 1)}\\\\V = -32t+4t^-1/2[/tex]
V = -32+2.391
v = -29.61m/s

Find the sum 46 +47 +48 +49+...+138 + 139.
Answer:
8695
Step-by-step explanation:
Took forever on calculator but I did it!
Answer:
8695
Step-by-step explanation:
There is a formula for adding all integers from 1 to some integer n.
[tex] 1 + 2 + 3 + ... + n = \dfrac{n(n + 1)}{2} [/tex]
In other words, to add all integers from 1 to an integer, multiply the integer by the next greater integer and divide by 2.
For example, what is
1 + 2 + 3 + 4 ?
Multiply 4 by the next integer, 5, and divide by 2.
(4 * 5)/2 = 20/2 = 10
Check: 1 + 2 + 3 + 4 = 3 + 3 + 4 = 6 + 4 = 10
We see that the formula works.
Now we need to apply that formula to this problem, but there's a little more to it.
If the problem were
1 + 2 + 3 + ... + 138 + 139, then we'd apply the formula and that would be it.
In this problem, though, we don't start the sum at 1. We start the sum at 46.
The trick here is to add all integers from 1 to 139, and then we subtract the sum of all integers from 1 to 45, so we are left with only the sum of the integers from 46 to 139.
Sum of integers from 1 to 139:
[tex] 1 + 2 + 3 + ... + 139 = \dfrac{139(139 + 1)}{2} = \dfrac{139(140)}{2} = 9730 [/tex]
Sum of integers from 1 to 45:
[tex] 1 + 2 + 3 + ... + 45 = \dfrac{45(45 + 1)}{2} = \dfrac{45(46)}{2} = 1035 [/tex]
Now we subtract the sum to 45 from the sum to 139.
46 + 47 + 48 + ... 138 + 139 = 9730 - 1035 = 8695

Imagine a spherical cell with a radius of 10 pm. What is the cells surface area in pm2? Its volume, in pm3? What is the ratio of surface area to volume for this cell? Now do the same calculations for a second cell, this one with a radius of 20 pm. Compare the surface-to-volume ratios of the two cells. How is this comparison significant to the functioning of cells? (Note. For a sphere of radius r, surface area = 4rcr2 and volume = rrr3. Remember that the value of it is 3.14.)
Answer:
comparing the two cells, we can see that the surface area to volume ratio gets smaller as the cell gets bigger, making it harder for optimum amount of material that is needed to sustain the cell to cross the cell membrane. If a cell should grow beyond a certain limit, enough material will not be able to cross the membrane to nourish the cellular volume.
Step-by-step explanation:
For the cell with radius r = 10 pm
The surface area is from the area of a sphere
Area A = [tex]4\pi r^{2}[/tex]
A= 4 x 3.14 x [tex]10^{2}[/tex] = 1256 pm^2
volume is calculated from the volume of a sphere
Volume V = [tex]\frac{4}{3}\pi r^3[/tex]
V = [tex]\frac{4}{3}[/tex] x 3.14 x [tex]10^{3}[/tex] = 4186.67 pm^3
Ratio of surface area to volume = 1256/4186.67 = 0.29
For the second cell with radius r = 20 pm
The surface area of the cell is
A = [tex]4\pi r^{2}[/tex] = 4 x 3.14 x [tex]20^2[/tex] = 5024 pm^2
Volume = [tex]\frac{4}{3}\pi r^3[/tex] = [tex]\frac{4}{3}[/tex] x 3.14 x [tex]20^{3}[/tex] = 33493.3 pm^3
Ratio of surface area to volume = 5024/33493.3 = 0.15
comparing the two cells, we can see that the surface area to volume ratio gets smaller as the cell gets bigger, making it harder for optimum amount of material that is needed to sustain the cell to cross the cell membrane. If a cell should grow beyond a certain limit, enough material will not be able to cross the membrane to nourish the cellular volume.

Use the Pythagorean Theorem to find the length of the leg in the triangle shown below. The figure shows a right triangle with one leg marked 20. The hypotenuse is marked 52.
Answer:
48
Step-by-step explanation:
The Pythagorean Theorem is:
[tex]a^2+b^2=c^2[/tex]
where [tex]a[/tex] and [tex]b[/tex] are the legs of the right triangle. [tex]c[/tex] is the hypotenuse of the triangle.
In this right triangle, we know that one leg is 20 and the hypotenuse is 52. Therefore,
[tex]a=20[/tex]
[tex]c=52[/tex]
Since we don't know the other leg, we can leave it as [tex]b[/tex]. Substitute the values into the theorem.
[tex]20^2+b^2=52^2[/tex]
Evaluate the exponents first.
⇒ 20²=20*20=400
⇒ 52²= 52*52= 2704
[tex]400+b^2=2704[/tex]
Since we want to find [tex]b[/tex], we must isolate [tex]b[/tex]. First, subtract 400 from both sides of the equation.
[tex]400-400+b^2=2704-400[/tex]
[tex]b^2=2704-400[/tex]
[tex]b^2=2304[/tex]
[tex]b[/tex] is being squared. The inverse of a square is a square root. Take the square root of both sides of the equation.
[tex]\sqrt{b^2}=\sqrt{2304}[/tex]
[tex]b=\sqrt{2304}[/tex]
[tex]b=48[/tex]
The length of the other leg is 48
