I’m sorry. But none of your choices are correct. The correct answer would be 3 and 4. Further more explaining= 3+ 2 times 4 is 24. 2x= 4. That equals 8 and 3 times 8 is 24
The length of pendulum is 2.485 feet
<h3><u><em>
Solution:</em></u></h3>
Given that,
The formula T= 2pi sqrt(L/32) relates the time, T, in seconds for a pendulum with the length, L, in feet, to make one full swing back and forth
<u><em>Therefore, the given formula is:</em></u>

We have to find the length of pendulum that makes one full swing in 1.75 seconds
So the modify the given equation to find "L"

Substitute T = 1.75 seconds and 

Thus length of pendulum is 2.485 feet approximately
Answer:
for the area of the Circle we use A=πd
A=3.14x12 A=37.68
for a rectangle it is A=ab
A=12x15 A=180
37.68+180=142.32
your answer is 142.32 m 2
F(-5) just means that your substituting the number -5 for every x value. So if you have x+1 this would be -5+1 which is -4
0 divided by 10 is just 0, so you should just write 5.0
