==================================================

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.

Answer:

Step-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

[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

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

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

Answer:

Step-by-step explanation:

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:

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.

The value of x when f(x) = 1 is  x = 2.

A relation between a collection of inputs and outputs is known as a function. A function is a connection between inputs in which each input is connected to precisely one output. Each function has a range, co-domain, and domain.

Given:

The function,

f(x) = 3x – 5.

Solving for x when f(x) = 1,

1 = 3x - 5

3x = 6

x = 2

Therefore, the value is x = 2.

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]

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.
