You would set the problem into slope-interslope form : y = mx + b.
Slope (m) = rate of change           b = y-intercept
Therefore, your in the above:
m =  3
b = 0
The constant proportionality (slope) is 3 and the y-intercept is 0.

Find the surface area of the cylinder formed by the net. Use 3.14 for π.
sineoko [7]

Answer:

138.16 square feet

Step-by-step explanation:

The surface area of the cylinder consists of one rectangle and two circles.

1. The radius of the circle is 4 ft, then the area of the circle is

A_{circle}=\pi r^2 =\pi \cdot 4^2 =16\pi \ ft^2

2. The width of the rectangle is 1.5 ft, the length of the rectangle is the circumference of the circle.

Find the circumference:

C=2\pi r=2\pi \cdot 4=8\pi \ ft

Hence,

A_{rectangle}=1.5\cdot 8\pi =12\pi \ ft^2

3. The surface area of the cylinder is

SA=2A_{circle}+A_{rectangle}=\\ \\=2\cdot 16\pi +12\pi =32\pi +12\pi =44\pi \approx \\ \\\approx 44\cdot 3.14=138.16\ ft^2

What is the following product?
Zarrin [17]

Answer: A

Step-by-step explanation:

(\sqrt{12}+\sqrt{6})(\sqrt{6}-\sqrt{10})

(\sqrt{12}*\sqrt{6})-(\sqrt{12}* \sqrt{10})+(\sqrt{6}*\sqrt{6})-(\sqrt{6}*\sqrt{10})

(\sqrt{12*6})-(\sqrt{12*10})+(\sqrt{6*6})-(\sqrt{6*10})

Let's rewrite the numbers inside to see if we can take some out.

For example; 12 is 3 x 4 and 4 is 2^2 which means a 2 will come out of the root.

(\sqrt{3*2^2*6})-(\sqrt{3*2^2*10})+(\sqrt{6^2})-(\sqrt{6*10})

(2\sqrt{18})-(2\sqrt{30})+(6)-(\sqrt{60})

We can also rewrite 18 as 9 x 2 and 9 can be rewritten as 3^2 which will make the 3 come out.

60 can be rewritten as 15 x 4 and 4 can be rewritten as 2^2 which will make the 2 come out.

Let's rewrite this.

(2\sqrt{2*3^2})-(2\sqrt{30})+(6)-(\sqrt{15*2^2})

When a number comes out of a root, it has to be multiplied by the number that is already outside.

(2*3\sqrt{2})-(2\sqrt{30})+(6)-(2\sqrt{15})

Solve and eliminate parentheses.

6\sqrt{2}-2\sqrt{30}+6-2\sqrt{15}
