Answer:

60.84 m

Step-by-step explanation:

The perimeter is the distance around

The distance around the 3 sides of the rectangle are

15+12+15

Now we are going 1/2 way around the circle

That is 1/2 of the circumference

1/2 C = 1/2 pi *d

= 1/2 pi *12

= 6pi

Using 3.14 for pi

= 6 (3.14)

=18.84

Add these together

42+18.84

60.84 m

Evaluate 5x²-3(x-2)+x for x=3

Zepler [3.9K]

Answer:

Step-by-step explanation:

Evaluate 5 x^2 - 3 (x - 2) + x where x = 3:

5 x^2 - 3 (x - 2) + x = 5×3^2 - 3 (3 - 2) + 3

3^2 = 9:

5×9 - 3 (3 - 2) + 3

3 - 2 = 1:

5×9 - 3 + 3

5×9 = 45:

45 - 3 + 3

45 + 3 = 48:

48 - 3

It took 12 days for all the 60 gallons of water to leak out of the barrel. If you divide 60 by 5 you will get 12.

Let f(x) = x2 - 81. Find f-1(x).

dusya [7]

This is equivalent to finding a function g in which $g(x^2-81)=x$ .

We simply reverse the actions of the initial function by adding 81 back and taking the square root. Therefore, $f^{-1}(x)=\sqrt{x+81}$ .
