A triangular pyramid has a height of 18 yards and a base with an area of 330 square yards. What is the volume of the pyramid?

WITCHER [35]

Answer:

option C. $V=1,980\ yd^{3}$

Step-by-step explanation:

we know that

The volume of the triangular pyramid is equal to

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

where

B is the area of the triangular base

h is the height of the pyramid

In this problem we have

$B=330\ yd^{2}$

$h=18\ yd$

substitute in the formula

$V=\frac{1}{3}(330)(18)=1,980\ yd^{3}$

ANSWER

Step 3

EXPLANATION

The given polynomial expression is:

$2 {p}^{2} - 3p - 7 - (3 {p}^{2} + p - 5)$

Fatau correctly expanded the parenthesis in the first step.

$2 {p}^{2} - 3p - 7 - 3 {p}^{2} - p + 5$

Fatau also correctly grouped the like terms to obtain:

$(2- 3) {p}^{2} + (- 3 - 1)p + (- 7 + 5)$

Fatau committed a mistake at the third step.

Instead of obtaining,

$- {p}^{2} - 4p - 2$

He mistakenly got:

${p}^{2} - 2p +2$

Compare rates of change.

MrMuchimi

Y=foot
x=foram

A. easy, plug 17 for x and evaluage for y
y=0.860(17)+3.302
y=14.62+3.302
y=17.922 inches

B. rate of change is slope
y=mx+b
m=slope
so
rate or change is 0.860 inches per legnth of forarm

C. what data

D. it is a function
since it is 1st degree (no exponents greater than 1 on the placeholder), and it is not a vertical line
it is a function
