Answer:

The variation in apparent gravitational acceleration (g) at different locations on Earth is caused by two things.The distance between the centers of mass of two objects affects the gravitational force between them, so the force of gravity on an object is smaller at the equator compared to the poles.

Gravity dose the same anywhere but may take longer depending on height. or weight. newton’s law of gravity supports this.

Evaluate 7+q(r−8)2 when q = 3 and r = 10.
liberstina [14]

<u>Answer:</u>

  • The solution of the expression is 19.

<u>Step-by-step explanation:</u>

<u>Given:</u>

  • q = 3
  • r = 10

<u>Work:</u>

  • => 7 + q(r − 8)2
  • => 7 + 3(10 - 8)2
  • => 7 + 6(10 - 8)
  • => 7 + 6(2)
  • => 7 + 12
  • => 19

Hence, <u>the solution of the expression is 19.</u>

Hoped this helped.

Cot (15 degrees)
STatiana [176]

Answer:

Part I: cot(15 degrees) = cot(45 - 30)

Part II: Evaluation is below

Step-by-step explanation:

<em>Everything is done in degrees</em>

<em />

Two angles that differ by 15 degrees that is easy to evaluate is 30 degrees and 45 degrees. The cot(15 degrees) = cot(45 - 30) = 1/tan(45-30) = (1+tan45tan30)/(tan30 - tan45) = (1+ sqrt(3))/(sqrt(3) - 1)

We rationalize this by multiplying 1+ sqrt(3) in the top and bottom, getting:

(4 + 2sqrt(3))/2 = 2 + sqrt(3)

I hope this helps! :)

Gavin thought he was making a good investment when he heard about an online grocery company. So he bought 500 shares in the comp
kirill [66]
The answer would be D) 98.8% because if the initial price is $25 per share, then Gavin would have spent $12,500. None of the other answers make sense since if it was just 3% or 82.3%, then it would be too much to equal $150 in return. If you were to put C, then the shares would equal $4.43 each, and If you bought 500 shares, then it would equal $2,212.5 which would be way more than $150. In the other hand, D is correct because then only 1 share would equal $0.3 and that multiplied by 500 equals precisely $150.

Hope this helps!

3) WILL MARK BRAINLIEST + 10 POINTS!!!!!! :)
Charra [1.4K]
 
This is really a long way to go to make something complicated
out of something simple.  The last choice does the job.

cos(180)  =  -1
sin(180)  =   0

So       4 [cos(180) + i sin(180) ]

       =   4 [ -1      +  i (0) ]

       =     -4     yay!
