Calculate the force between two touching grapefruits each with a radius of 0.08 meters and a mass of 0.45 kg
The force between two touching grapefruits each with a radius of 0.08 meters and a mass of 0.45 kg is 5.27 * 10⁻¹⁰ N
Newton's law of gravitation is given by:
F = Gm₁m₂/r²
Where F is the force, m₁, m₂ are masses, r is the distance between the two masses and G is the gravitational constant = 6.67 * 10⁻¹¹ Nm²/kg²
Given that m₁ = m₂ = 0.45 kg, r = 0.08 + 0.08 = 0.16 m, hence:
F = 6.67 * 10⁻¹¹ Nm²/kg² * 0.45 kg * 0.45 kg / 0.16²
F = 5.27 * 10⁻¹⁰ N
The force between two touching grapefruits each with a radius of 0.08 meters and a mass of 0.45 kg is 5.27 * 10⁻¹⁰ N

Estimate the average rate of change between x = 0 and x = 2 for the function shown
A. 4
B. 5
C. 10
D. 11
Answer:
4Step-by-step explanation:
Let the function given be f(x) = x³
The formula for calculating the average rate of change is expressed by:
f'(x) = [tex]\frac{f(x+h)-f(x)}{h}[/tex]
If f(x) = x³
f(x+h) = (x=h)³
substitute the functions in the formula
[tex]f'(x) = \frac{(x+h)^3-x^3}{h}\\f'(x) = \frac{(x^3+3xh^2+3hx^2+h^3)-x^3}{h}\\f'(x) = \frac{3xh^2+3hx^2+h^3}{h}\\f'(x) = \frac{h(3xh+3x^2+h^2)}{h}\\f'(x) = 3xh+3x^2+h^2[/tex]
Since h = x₂-x₁ and x = 0
[tex]f'(x) = 3(0)(2-0)+3(0)^2+(2-0)^2\\f'(x) = 0+0+2^2\\f'(x) = 4\\[/tex]
Hence the average rate of change is 4

11. The surface area of a rectangular solid with length 6 centimeters and width 3 centimeters is 72 square
centimeters. Find the height.
Answer:
4 cm
Step-by-step explanation:
The formula for volume is V=L*W*H. We are given all except the height, making it 72=6*3*H. Multiply 6*3 will give you 72=18H. Divide by 18 and you’ll get 4cm.
TL;DR
72=6*3*H
72=18H
4=H
2 + 1.25f =10-2.75f
Answer:
f = 2
Step-by-step explanation:
2 + 1.25f =10-2.75f
Add 2.75f to each side
2 + 1.25f+2.75f =10-2.75f+2.75f
2+ 4f = 10
Subtract 2 from each side
2+4f-2 = 10-2
4f = 8
Divide each side by 4
4f/4 = 8/4
f = 2
Answer:
2

The range has to be within 1-5, if its over, we know we won't have to get the wrong answer. For me, I honestly guessed the number 3, but then I had to put in each number in the equation. 2 was the solution, because they ended up the same.
2 + (1.25 * 2)
2 + 2.5 = 4.5
10 - (2.75 * 2)
10 - 5.5 = 4.5
4.5 = 4.5
Therefore the answer is 2.

Which is the best estimate of 61.4 + 88.3?
A. 100
B. 140
C. 150
D. 200
C.150
Step-by-step explanation:
It is the closest to the answer and you would get closest to that even without really needing to work anything out
The best estimation of summation 61.4 + 88.3 after rounding to the nearest whole number is 150.
How do round any digit?To round up or down tens place then we need to look at the unit place if it is less than 5 then we need to keep it as it and if it is greater than 5 then we need to round up tens digit.
Given the sum,
61.4 + 88.3
61.4 + 88.3 = 149.7
Now the decimal place is 7 and if the decimal place is greater than 5 then we can round up the digit.
So,
149.7 → 14(9 + 1) = 150
Hence "Summation 61.4 + 88.3 is best approximated as 150 after being rounded to the next whole number".
