Answer:
C. 586.2 cm²
Step-by-step explanation:
Area of the figure = area of triangle + area of rectangle + area of semicircle
= (½*b*h) + (L*W) + ½(πr²)
Where,
b = 18 cm
h = 7 cm
L = 22 cm
W = 18 cm
π = 3.14
r = ½(18) = 9 cm
Substitute
Area = (½*18*7) + (22*18) + ½(3.14*9²)
Area = 63 + 396 + 127.17
Area = 586.17 ≈ 586.2 cm²
Answer:
y = ±√(x-16)
Step-by-step explanation:
To find the inverse of an equation, swap the x- and y-variables:
y = x² + 16
x = y² + 16
Then, solve for the y-variable:
x = y² + 16
y² = x - 16
y = ±√(x-16)

Answer:
x in {-6, -2, 4}
Step-by-step explanation:
The zero product rule tells you that a product will be zero if and only if one of the factors is zero. These binomial factors are zero when x has a value that is opposite the constant of the binomial.
x +6 = 0 ⇒ x = -6
x -4 = 0 ⇒ x = 4
x +2 = 0 ⇒ x = -2
The zeros of the function are the x-values -6, -2, and 4.
Answer: 600 dollars
Step-by-step explanation: 75% is 3/4 so you divide 450 by 3 to get 150. So you know for 1/4 the price is 150 dollars. Now that you know that you can multiply 150 4 times to get the full amount. 150*4=600
