a play court on the school playground is shaped like a square joined by a semicircle.the perimeter around the entire play court

Drupady [299]

Answer:

Step-by-step explanation:

Perimeter of square = 182.8 ft

Perimeter of semicircle = 62.8 ft

Let teh side of the square is a and the radius of semi circle is r.

Perimeter of square = 4a

4a = 182.8

a = 45.7 ft

perimeter of semicircle = π r

π r = 62.8

r = 20 ft

Area of square part = a² = 45.7 x 45.7 = 2088.5 ft²

Area of semicircle = πr²/2 = 3.14 x 20 x 20 /2 = 628 ft²

Total area of the play court = 2088.5 + 628 = 2716.5 ft²

State the domain of 1b, then determine the equation of any vertical asymptotes and/or coordinates of any holes in the graph of t

Katena32 [7]

We have

$f(x)=\frac{2x^2+x}{x^2-5x+6}$

First we will factorize the function

$f(x)=\frac{x(2x+1)}{\mleft(x-2\mright)(x-3)}$

The domain is

$\: \mleft(-\infty\: ,\: 2\mright)\cup\mleft(2,\: 3\mright)\cup\mleft(3,\: \infty\: \mright)$

In this case, we have two vertical asymptotes

x-2=0

x=2

x-3=0

x=3

ANSWER

The domain is

$\: \mleft(-\infty\: ,\: 2\mright)\cup\mleft(2,\: 3\mright)\cup\mleft(3,\: \infty\: \mright)$

The vertical asymtotes

x-2=0

x=2

x-3=0

4x + 2 < −2 OR 4x + 2 > 26 <br><br><br> solve pl

inn [45]

Step-by-step explanation:

The easiest thing to do here is:

4x + 2 = -2 and 4x + 2 = 26

Just know whaever you get for x is greater or less than the actual answer.

4x + 2 = -2

- 2 - 2

4x = -4

$\frac{4x}{4} = \frac{-4}{4}$

x = -1 <--- Because -2 is supposed to be greater than x, x equals any number less than -1 but not -1.

4x + 2 = 26

- 2 - 2

4x = 24

$\frac{4x}{4} = \frac{24}{4}$

x = 6 <--- Because 26 is supposed to be less than x, x equals any numbey greater than 6 but not 6

Ivan evaluated the expression 8+12÷3×2 and got 10. What mistake did he make?

lesya [120]

Ivan forgot to follow PEMDAS
Division first
12/3 = 4
4 x 2 = 8
8 + 8 = 16
Hope this helps!
