Answer: A. 87 feet
Step-by-step explanation:
1. You can find the t value of the vertex of the parabola as following:

2. Substitute values:
a=-16
b=70
Then:

3. Substitute the vaue obtained into the equation given in the problem. Therefore, you obtain the following result:

4. To the nearest foot:
h=87 feet
Answer:
A) 4π
Step-by-step explanation:
The period of a secant function, f(x)=a*sec(bx+c)+d, is defined as 2π/|b| where b is the distance of the period. Since we know b=1/2 given by the function, then the period is 2π/|1/2|=2π/(1/2)=2π(2/1)=4π.
Answer:
4 2/7
Step-by-step explanation:
- x * 9 4/5 = 42
- x * 49/5 = 42
- x = 42 : 49/5
- x = 42 * 5/49
- x = 30 /7
- x = 4 2/7
