How do i solve #13? (linear equations)

Neporo4naja [7]

#12:

Assuming that I have those points correct: (1, 5) and (-4, -10), the slope of this line is

5-(-10)

m = --------------- = 15/5 = 3

1-(-4)

The line passes thru the origin, so the y-intercept is 0.

So the equation of this line is y = 3x.

I see no marks (points) in the illustration for #13.

I need help to find the answer to this problem

navik [9.2K]

Answer :

Therefore, the area of the pool cover = 380.285 feet square

while the length of the rope equals 69.14 feet.

Explanation:

From the question, the pool has a diameter of 20 feet and the cover extends 12 inches

we need to convert 12 inches to feet

so 12 inches is equivalent to 1feet

Since the pool is circular, we need to use the formula for finding the area of a circle

Area of circle =

$\pi r^2$

Now, the radius of the pool equals half of the diameter of the pool

The radius of the pool =

$\frac{1}{2}\times20=10$

Also, the radius of the cover will be = radius of the pool + 12 inches(converted to 1 feet)

hence, the radius of the cover =

$10+1=11$

Now, using the formula for the area of circle=

$\begin{gathered} \pi r^2 \\ =\frac{22}{7}\times11^2=\frac{(22\times121)}{7} \\ =380.285ft^2 \\ ^{} \\ \\ \end{gathered}$

Therefore the area of the pool cover = 380.285 feet square

Also, the length of the rope would be the perimeter of the pool cover which is calculated using the formula for finding the perimeter of the circle

which is:

$=2\pi r$

Hence the lenght of the rope =

$\begin{gathered} =2\pi r \\ =2\times\frac{22}{7}\times11 \\ =69.14ft \end{gathered}$

Therefore, the area of the pool cover = 380.285 feet square

while the lenght of the rope equals 69.14 feet.

The projected worth (in millions of dollars) of a large company is modeled by the equation w = 206(1.1) t. The variable t repres

kupik [55]

Answer:

Hey There!! The Correct answer is: The equation is w = 241(1.06)t

And here variable t represents the number of years since 2000.

In 2001 means t=2001 -2000 = 1

So we plug 1 for t in the given expression , that is w = 241(1.06)1 = 241 * 1.06 = 255.46

Therefore in 2001, it should be worth to 255.46.

And in the given expression 1.06=1 +0.06, where 0.06 is the annual percent of growth that is 6 % .
