Answer:


Step-by-step explanation:
Given

Solving (a): Equation when it hits the ground.
This means that 
So, we have:


Solving (b): The value of t in (a)

Using quadratic formula, we have:

This gives:




Split



Time can't be negative; So:

Answer:
Step-by-step explanation:
- sqrt(39) and square root 47
are the limits. The - square root of 39 is smaller than - 6. So the integer to use here is - 6
sqrt (47) = 6.686. Here the square root is larger than the closest integer.
The integer to use is 6
- 6 + 6 = 0
<span>constant sum = 4 + 5 = 9</span>
Answer: C
<u>Step-by-step explanation:</u>
Varies inversely means xy = k
A. 1(-3) = -3
2(-9) = -18
-3 ≠ -18
B. 1(-6) = -6
2(-12) = -24
-6 ≠ -24
C. 1(6) = 6
2(3) = 6
3(2) = 6
6 = 6 = 6 This works!
D. 1(-3) = -3
2(2) = 4
-3 ≠ 4
The only table that has the same k-value is option C.
The dimensions are 2 ft. by 6 ft. 2*6 is 12, the area. 2+2+6+6 is 16, the perimeter.
