Plug in 3 to x:
f(x) = 3³ - 7
Solve:
f(x) = 3³ - 7
f(x) = 3 · 3 · 3 - 7
f(x) = 9 · 3 - 7
f(x) = 27 - 7
f(x) = 20

Answer: 0 ≤ x ≤ 4.75
Step-by-step explanation: Domain is the range of possible x values that make sense in the equation. Since the x values are time, and there cannot be negative time, x must obviously be positive. And since y is height and height can't be negative, the domain of x ends at the x-intercept, the point at which y begins to become negative. So the domain of x is 0 is less than or equal to x which is less than or equal to about 4.75.

Answer:
60.96
Step-by-step explanation:
1 inch = 2.54
so to know what 24 inch = you can multiply 24 time 2.54 and you should get the answer
2.54 time 24= 60.96
Here, I think I can help you out:
1. 21 ÷ 3
= 7
Therefore, the length is 7cm².
2. 35 ÷ 7
= 5cm²
- And so on. Simply divide the area by the length of the side given; you can answer up to question six using this strategy.
7. All sides of a square are the same length.
7 x 7
= 49cm²
9. 2 x 3.5
= 7m²
- The formula to find the area of a square/rectangle is length x width. Just multiply the given lengths for the answers :)
