Answer:

Step-by-step explanation:

3(1+6r)=14-12 Write out formula.

3+18r=2 Distributive Property Form.

(3-3)+18r=2-3 Subtract 3 to both sides.

(18/18)r=-1/18 Divide both sides by 18

r=0.055555..... or -1/18.

Answer:

148 square inches

Step-by-step explanation:

Step 1: finding the area of the base (upper base plus lower base)

2( L x W).

2 (6in. x 5in.)

2( 30 square inches.)

60 square inches

Step 2: finding the area of first 2 sides

2 ( l x w)

2 ( 5in x 4in)

2 ( 20 square inches.)

40 square inches

step 3: finding the area of the last 2 sides

2(lxw)

2(4in.x 6in.)

2(24 square inches.)

48 square inches

step 4: combine all the answers.

60 square inches. + 40 square inches. + 48 square inches = 148 square inches

Given sec(theta)= 5... find cot(90-theta)

Mumz [18]

$\sec(\theta)=\frac{1}{\cos(\theta)}
\\
\\\cos(\theta)=\frac{1}{\sec(\theta)}=\frac{1}{5}
\\
\\ \sin^2\theta+\cos^2\theta=1
\\
\\\sin\theta= \sqrt{1-\cos^2\theta}= \sqrt{1-( \frac{1}{5})^2 } = \sqrt{1- \frac{1}{25} } = \sqrt{ \frac{25}{25} -\frac{1}{25} }=\frac { \sqrt{24}}{5} 
\\
\\ \cot(90^o-\theta)=\tan{\theta}= \frac{\sin\theta}{\cos\theta} = \frac{\frac { \sqrt{24}}{5} }{ \frac{1}{5} } = \sqrt{24} = \sqrt{4\times6}=2 \sqrt{6} 
\\
