A = 1/2 h (a+b)
A / 1/2 h = a + b
A / 1/2 h - b = a

a = A / 1/2 h - b

Hope this helps

Veseljchak [2.6K]

Answer:

3694.5 yd^3

Step-by-step explanation:

cone volume equation:

π x $r^{2}$ x $\frac{h}{3}$

π (28 yd/2)^2 x (18/3)

π x 196 x 6

3694.5 yd^3

Write the equation of the line that passes through the points (-2,-5)(−2,−5) and (8,-8)(8,−8). Put your answer in fully reduced

Nadya [2.5K]

Answer:

y= -0.3x - 5.6

Step-by-step explanation:

m= (-5)-(-8)/(-2)-8

m= -0.3

y=mx+c

-8= -0.3(8)+c

-8= -2.4 +c

-8+2.4=c

c= -28/5

y= -0.3x - 5.6

The result of expanding the trigonometry expression $\sin^2(\theta) * (1 + \cos(\theta))$ is $cos^0(\theta) + \cos(\theta) - \cos^2(\theta) - \cos^3(\theta)$

<h3>How to evaluate the expression?</h3>

The expression is given as:

$\sin^2(\theta) * (1 + \cos(\theta))$

Express $\sin^2(\theta)$ as $1 - \cos^2(\theta)$ .

So, we have:

$\sin^2(\theta) * (1 + \cos(\theta)) = (1- \cos^2(\theta)) * (1 + \cos(\theta))$

Open the bracket

$\sin^2(\theta) * (1 + \cos(\theta)) = 1 + \cos(\theta) - \cos^2(\theta) - \cos^3(\theta)$

Express 1 as cos°(Ф)

$\sin^2(\theta) * (1 + \cos(\theta)) = cos^0(\theta) + \cos(\theta) - \cos^2(\theta) - \cos^3(\theta)$

Hence, the result of expanding the trigonometry expression $\sin^2(\theta) * (1 + \cos(\theta))$ is $cos^0(\theta) + \cos(\theta) - \cos^2(\theta) - \cos^3(\theta)$
