The graph of a function f(x) is shown below: plot ordered pairs negative 1, negative 3 and 0, 1 and 1, 2.2 and 2, 3

JulijaS [17]

we have the points

$A(-1,-3)\\B(0,1)\\C(1,2.2)\\D(2,3)$

Using a graphing tool

see the attached figure

the domain is the interval---------> $[-1,2]$

$-1 \leq x\leq 2$

the range is the interval--------> $[-3,3]$

$-3 \leq y\leq 3$

therefore

<u>the answer is the option D</u>

integers from $-1 \leq x\leq 2$

Pyramid A is a square pyramid with a base side length of 7 inches and a height of 6 inches. Pyramid B has a volume of 3,136 in?.

anygoal [31]

Answer:

WE HAVE FIND HOW MUCH MAY TIME BIGGER IS THE VOLUME OF PYRAMID B THAN PYRAMID A.

The answer is 32 times

Step-by-step explanation:

Volume of Pyramid B = 3136 in³

Volume of Pyramid A = ?

We have to find volume of Pyramid A. As Pyramid is a square pyramid, its volume is given as:

$V=\frac{(b^2)(h)}{3}$

where b = base = 7 and h = height = 6. Substitute the values:

$V=\frac{7^2\cdot6}{3}\\V=98\\$

Volume of Pyramid A = 98 in³

To find how many time B is bigger than A, divide volume of B by A:

$\frac{3136}{98}=32$

So, volume of Pyramid B is 32 times bigger than volume of Pyramid A
