F(x) = √(5x + 7)
g(x) = √(5x - 7)
(f + g)(x) = f(x) + g(x)
(f + g)(x) = √(5x + 7) + √(5x - 7)
Answer: C)
We can find that the formula is:

We are told that the cannonball reaches its maximum height at t = 4.5 seconds. To find the maximum height, let's just plug this into the formula:

The height is 324 feet. We're done!
Answer:
what does oc mean?
Step-by-step explanation:
ANSWER: 312 3/8
So Volume is Length • Width • Height
So first we would put it into this formula:
8.5 • 5.25 • 7= 312.375, or, 312 3/8
The cows of Argentina needs an approximate area of 4200 m² for grazing, and there is a total of 4500 cows.
And we are asked to find the total area of their grazing but in hectares. So, we can write:

Then, for 4500 cows:


We know that, 1 hectares = 10000 m² = 10⁴ m²
Then let the area of the field be x in hectares:


Then, putting them in proportion, We will get:


So, the total area in hectares = <u>1</u><u>8</u><u>9</u><u>0</u><u> </u><u>hectares</u><u>.</u>
And we are done !!
