Answer:

Option A is correct

(-\frac{3}{2}, 4)

Step-by-step explanation:

Given the system of equations:

4x+3y = 6                  ......[1]

2x+2y = 5                   .....[2]

Multiply equation [2]  by 2 to both sides we have;

4x+4y = 10                     ......[3]

Subtract [1] from [3] to eliminate x we have;

4x+4y-4x-3y=10-6

Combine like terms;

y = 4

Substitute this in [1] we have;

4x+12 = 6

Subtract 12 from both sides we have;

4x = -6

Divide both sides by 4 we get;

x = -\frac{3}{2}

therefore, the solution of the given system of equations is:

(-\frac{3}{2}, 4)

Given the function f(x) = 5^x, Section A is from x = 0 to x = 1 and Section B is from x = 2 to x = 3. Part A: Find the average r
Masteriza [31]
Part A)

f(x) = 5^x
f(0) = 5^0
f(0) = 1
----------
f(x) = 5^x
f(1) = 5^1
f(1) = 5
----------
f(x) = 5^x
f(2) = 5^2
f(2) = 5*5
f(2) = 25
----------
f(x) = 5^x
f(3) = 5^3
f(3) = 5*5*5
f(3) = 125

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

Rate of change for section A = (f(1) - f(0))/(1 - 0)
Rate of change for section A = (5 - 1)/(1 - 0)
Rate of change for section A = 4/1
Rate of change for section A = 4

Rate of change for section B = (f(3) - f(2))/(3 - 2)
Rate of change for section B = (125 - 25)/(3 - 2)
Rate of change for section B = 100/1
Rate of change for section B = 100

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

Part B)

From part A) above, we found,

Rate of change for section A = 4
Rate of change for section B = 100

Which means that section B's rate of change is 25 times greater (since 100/4 = 25, or 25*4 = 100)

Answer for part B: 25

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

Extra:  Explain why one rate of change is greater than the other.

The rate of change for section B is larger because the exponential function is growing faster as x increases. This is shown visually by the sharper and steeper incline as the function curve goes upward. The function starts off with relatively slower growth but it accelerates in speed.

Aileen is a salesperson at Lopez Sporting Goods. She is paid a monthly commission on all Little League uniforms she sells. She r
spayn [35]

The  total value of the uniform Aileen sold is x= 2260 on monthly Commission sells.

Given,

Let us assume the all little League uniform = x

Aileen first commission 10% of 2000$ in sales.

Aileen Second Commission 12% of (x-2000)$

Total Commission Aileen Earner = 10% ×2000 + 12% × (x-2000)

                                       231.2   = 0.1× 2000 + 0.12× (x-2000)

                                        231.2   = 200 + (0.12x - 240 )

                                        231.2   = 200 +  0.12x - 240

   After Transformation, we get

                                        0.12x = 231.2 - 200 +240

                                        0.12x = 271.2

                                               x = 271.2/.12

                                               x = 2260

Aileen Sell the total value of Lopez Sporting Goods Uniform is 2260.

So the final Answer is  x = 2260$.

To function properly, a water outflow pipe must drop 1 inch for every 22 inches of horizontal distance.
Hitman42 [59]
<span>a. Calculate the slope for this drain pipe.
1/22
b. A rainwater pipe 30 feet long must run under the edge of a roof. What is the minimum vertical distance the pipe must drop between its ends?

Turn 30 feet to inches so 30 * 12  = 360 inches
Now times 1/22 x 360 = 16.32 inches . If they want it in feet just change 16.32 to feet by dividing 16.32 / 12

c. A design calls for a drainage pipe to cross a building 45 feet wide as it drops 25 inches. Is this pip steep enough to function properly? Explain.
Change 45 feet to inches so 45 * 12 = 540

Now times 540 * 1/22 = 24.54 inches so 25 inches would be steep enough since it droops 25 inches. </span>
