Answer:
4. About 2,700 in2
Step-by-step explanation:
The area of a circle (), measured in square inches, is directly proportional to the square of its diameter (), measured in inches. That is:
Where is the constant of proportionality, dimensionless.
In consequence, the following relationship between circles A and B is obtained:
The area of the circle B is now cleared:
Given that , and , then:
Therefore, the correct answer is 4.
The answer is g(x) = (1/4 x)^2
It has a horizontal stretch of 4. Since it is horizontal it goes inside the parentheses and becomes the reciprocal of 4 which is 1/4
Hope this helped!

Answer:
3/4 or 0.75
Step-by-step explanation: y+-2x3/2
0= -2x 3/2=2x-3/2=x+-3/4=X=3/4 or 0.75
Answer:
5x^2 + 4x + 3.
Step-by-step explanation:
While I'm a little confused on what is closed and open parenthesis/brackets, I think I understand what you mean. In (5x^2+3x-2)+(3x-2x+5), the brackets can simply be removed as there is no multiplication between them. This means we get 5x^2 + 3x - 2 + 3x - 2x + 5. Combining like variables, we get 5x^2 + 4x + 3.
Answer:
B: Permutation; Number of ways = 60
Step-by-step explanation:
First we have to decide if this is a problem of permutation or combination. The rule is:
- If the order matters, permutations will be used
- If order does not matter, combinations will be used
In this problem, they order of awarding the medals matters, so this is a permutation problem.
We have to award 3 medals among 5 runners. So this can be done in 5P3 ways:
Therefore, there are 60 ways to award the medal. Therefore, the correct answer is B.
