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
Answer:
A: The x-intercept of k(x) is half the x-intercept of h(x)
Step-by-step explanation:
Answer choices B, C, and D are concerned with slopes and y-intercepts. The coefficients of x in the functions are different and are related by a factor of -2, so the lines are not parallel, and one slope is not twice the other. The y-intercepts (constants) in each function are different, so they graphs do not cross the y-axis at the same place.
Hence answer choices B, C, and D can be eliminated.
The x-intercepts are found by setting y=0 and solving for x:
h(x) = 0 = -2x +4 ⇒ x = 4/2 = 2
k(x) = 0 = 4x -4 ⇒ x = 4/4 = 1
The x-intercept of k(x) is half that of h(x). . . . . . . matches choice A
Answer:
1. x+4x
2. 5x
3. 
4. 4x-2x+15
5. 
Step-by-step explanation:
To write expressions remember these key words:
- a number is a variable like x
- sum is +
- difference and subtracted is -
- quotient is ÷
- product is ×
- reciprocal means flip like

- square is an exponent of 2 like

1. x+4x
2. 5x
3. 
Remember a quotient would be
but the reciprocal is
.
4. 4x-2x+15
5. 
Answer:
none of these numbers are not right the real answer is 1088
Step-by-step explanation:
17 x 4 = 16
16 x 4 = 272
272 x 4 = 1088
