Answer:

y =  \sqrt{x}

D

Step-by-step explanation:

Literally substitute one of the points (4,2), using some common sense, the x is larger than the y, so it can't be A or B (makes 4 larger) and really just pur 4 in option C, it won't be a pretty nice number. So the only option is D.

Jim is painting the inside of a circular helicopter pad. How many cans of paint would he need if the pad is 50 feet across and e
Inessa [10]

Answer:

Number of can needed to paint inside of the circular helicopter pad = 1

Step-by-step explanation:

The circular pad is given to be 50 feet across.

⇒ Circumference of the circular pad = 50 feet

⇒ 2π·r = 50

⇒ π·r = 25

⇒ r = 7.96 feet

Now, Area of the circular pad = π·r²

⇒ Area = 3.14 × 7.96²

⇒ Area = 198.96 square feet

Now, one can of paint covers 200 feet² area of the pad

Hence, 198 feet² area can also be painted by using one can.

Therefore, number of can needed to paint inside of the circular helicopter pad = 1

Problem 3
Murljashka [212]

Answer:

-\frac{2}{5}

Step-by-step explanation:

Given expression:

           2x + 5y = -10

The equation of a straight line is;

            y = mx + c

y and x are the coordinates

m is the slope

c is the intercept

 Now;

          let us write the given expression in slope intercept format;

            2x + 5y  = -10

                    5y = -2x - 10

                     y = -\frac{2x}{5}  - 2

So, the slope of the line is -\frac{2}{5}

The total length of two ships is 1841 feet. The difference in their lengths is 13 feet. Find the length of each ship.
lilavasa [31]

9514 1404 393

Answer:

  927 ft

  914 ft

Step-by-step explanation:

The lengths are half the sum plus or minus half the difference:

  1841/2 ± 13/2 = {1854/2, 1828/2} = {927, 914} . . . feet

__

Let x represent the shorter length. Then x+13 is the longer length. Their total is ..

  x +(x +13) = 1841

  2x = 1841 -13

  x = (1841 -13)/2 . . . . half the sum minus half the difference

Then the longer length is ...

  x+13 = (1841/2) -(13/2) +13

  x +13 = (1841/2) +(13/2) . . . . half the sum plus half the difference
