BigorU [14]

I will do a and b and you do the rest.


For (a), the equation is x + y = 154.


For (b), the equation is 320x + 85y = 14,970.


We have two equations in two unknowns.


Use the substitute method to find x and y (the given c). Once you have x and y, use that to find d.


Take it from here.

a window is shaped like a parallelogram. the height of the window is half the length of the base of the window. the base of the
rusak2 [61]

The area of the parallelogram is 36 inches square.

We have a parallelogram shaped window whose dimensions are as follows-

base (b) : 12 inches

height (h) : \frac{1}{2} \times 12 = 6 inches

Other side = 10 inches

We have to find the area of the window.

<h3>What is the formula to calculate the area of a parallelogram of given base (b) and height (h).</h3>

The area of the parallelogram is given by -

A = \frac{1}{2} \times base\times height

In the question given - We can apply the above formula to estimate the area of the window.

A = \frac{1}{2} \times 12\times6 = 36 inches square.

Hence, the area of the parallelogram is 36 inches square.

Find the average rate of change of f(x)=4x^2-6 on interval [1,a]​
stiv31 [10]

9514 1404 393

Answer:

  4a +4

Step-by-step explanation:

The average rate of change of f(x) on the interval is ...

  (f(a) -f(1))/(a -1)

  = ((4a² -6) -(4(1)² -6))/(a -1) = (4a² -4)/(a -1)

  = 4(a² -1)/(a -1) = 4(a +1) = 4a +4

The average rate of change on the interval is 4a +4.
