Answer:
π^2, 9.8 repeating, square root of 99.
Step-by-step explanation:
Sugar: x pounds
flour: 2x + 5 pounds
2x + 3(2x + 5) = 40
2x + 6x + 15 = 40
8x = 25
x = 3.125
-> a sack of flour is 3.125 + 5 = 8.125 pounds
I hope it‘s coorect

Answer: Yes, 
<u>Step-by-step explanation:</u>
f(x) = 3x - 6 is a line so it is a function because
it passes the vertical line test
and the horizontal line test
To find the inverse, swap the x's and y's and solve for y
Answer:
(1) 39 feet
Step-by-step explanation:
Feris wheel moves in a circular pattern. But if you take imaginary horizontal and vertical lines from your location to the Ferris wheel's center, you can wee see this make a triangle. This question is about trigonometry. Horizontal distance is the adjacent side and vertical distance is the opposite side. Your straight line distance to the center is the hypotenuse(45 feet). Then we can solve the question using the sin formula.
sin x = opposite/hypotenuse
sin 120 = vertical distance/ 45 feet
vertical distance = 0.8660 * 45 feet
vertical distance =38.97 feet = 39 feet
