Let original Hieght be X

reduction = 32% = 32/100 X

new hieght = 4.42 m

now, 4.42 = X + 32/100 X

4.42 = 132/100 X

X = 4.42 * 100 / 132

X = 3.34 m

Original Hieght = 3.34 m

Use the graph that shows the solution f(x) = G (x)

Bingel [31]

Answer:

The correct options are A and C.

Step-by-step explanation:

The given functions are

$F(x)=-\frac{3}{4}x^2+3x+1$

$G(x)=2^x$

We have to find to solution for the equation

$F(x)=G(x)$

$-\frac{3}{4}x^2+3x+1=2^x$

The solution of the above equation is the intersection of F(x) and G(x).

From the graph it is noticed that both graph intersects each other at (0,1) and (2,4).

The x-coordinates of these points are the solutions of the given equation.

Therefore the solution of given equation are 0 and 2.

Therefore option A and C are correct.

the length of a rectangle is 7 inches more than its width, if the perimiter of the rectangle is 66 inches, find its dimensions.

Maurinko [17]

Perimeter of rectangle=66
length of rectangle=L
width of rectangle=w
P of a rect.= 2(length)+ 2(width)
66= 2L+2w

if the length is 7in more than the width, then
L=7+w

Now we will substitute 7+w in for L. Here is our new equation:

66=2(7+w) + 2w

Solve for w

66=14+2w+2w
66=14+4w
52=4w
w=13
L=7+13, so L=20

I hooe this is explained well enough
