Answer:
5x^4-24x^3-55/x^2
Step-by-step explanation:
I have the solution in my notes but it's too long✌️

Step-by-step explanation:
- Masses of the bodies are x and y
- Distance at which they are kept is r
- When two bodies are of masses x and y are placed at a distance r then the gravitational force acting on them is given as:

- Where G is the gravitational constant.
Answer:
c. 30.9 °C; 32.9 °C
Step-by-step explanation:
Put the given numbers into the given formula and do the arithmetic.
(a) The temperature of sample 1 is ...
y = (100 -24)e^(-0.12·20) + 24 ≈ 30.9
___
(b) The temperature of sample 2 is ...
y = (100 -4)e^(-0.12·10) +4 ≈ 32.9
<span>120 - 36 is 84 just as 12(10 - 3) = 12 x 7 = 84.</span>
