Answer:

$307,572\ ft^{3}$

Step-by-step explanation:

we know that

The volume of a pyramid is equal to

$V=\frac{1}{3}Bh$

where

B is the area of the base of the pyramid

h is the height of the pyramid

Find the area of the base B

$B=114^{2}=12,996\ ft^{2}$

we have

$h=71\ ft$

substitute the values

$V=\frac{1}{3}(12,996)(71)=307,572\ ft^{3}$

F(x)= x^2 -16x+63 find the x-intercepts of this function

Ahat [919]

Answer:

The x-intercepts will be, x= 7 or x =9

Step-by-step explanation:

f(x)= x^2 -16x+63

At the x-intercept, f(x) is zero.

Therefore;

x² - 16x + 63 = 0

solving it quadratically;

product = 63

Sum = -16

x² - 9x - 7x + 63 = 0

x(x-9) - 7( x-9) = 0

(x-7) (x-9) = 0

x = 7 or x = 9

Therefore;

The x-intercepts will be, x= 7 or x =9
