The formula for the radius of a sphere is:
r(s) = sqrt[s/(4pi)]
This is based on the formula that s = 4pi*r^2
As can be seen, as the surface area increases, s/4pi increases, and sqrt(s/4pi) will also increase, meaning that the radius will increase. This continues until the balloon reaches the maximum s = 1500 cm^2.
The correct answer is the first choice:
<span>As the surface area of the balloon increases, the radius of the balloon increases until the maximum surface area is reached.</span>
Answer: 20inch
Step-by-step explanation:
Using the Pythagoras theorem:-
25^2 = 15^2 + x^2 where x = the width of the screen.
625 = 225 + x^2
x = √(625 - 225) = √400
= = 20 ins
The complete question is
"What is the component form of the vector represented by 2a when a =⟨−2,3⟩?"
The Component form of the vector represented by 2a is (-4,6)
<h3>What is the component form of a vector?</h3>
The component form of a vector is represented by (x, y) that has gone x units left to the origin and y units up from the origin.
Given, a=(-2,3)
By using scalar multiplication,
2a = (2(-2), 2(3))
2a = (-4,6).
Therefore the component form of 2a=(-4,6)

For a monthly sales figures at 5600 and expected to fall for the following 9 months at a rate of 2% each month, the total sales for the next two years is mathematically given as
A=11968.04
<h3>What are total sales for the next two years (including the first January).?</h3>
Generally, the total sales is mathematically given as
A=5600(1-2/100)^9(1+4/100)^24
A=5600(.98)^9(1.04)^24
A=11968.04
In conclusion, total sales for the next two years
A=11968.04
