Total area of five circles of radius r is 5pi r^2
Total area of three circles of radius s is 3pi s^2
If A = B, then 5pi r^2 = 3pi s^2
r^2 / s^2 = 3/5
Therefore r/s = sqrt(3) / sqrt(5)
Answer:
224
Step-by-step explanation:
Hello!
To find f(-7) you simply plug the value, -7, into the function.
This will get you:
f(-7) = 4(-7)^2 - 4(-7)
Remember that the square of a negative number is a positive! Also, remember to use the order of operations (PEMDAS)!
This will get you:
f(-7) = 4(49) - 4(-7)
f(-7) = 196 - (-28)
f(-7) = 224
Hope this helps!
Answer:
118.6 or 119
Step-by-step explanation:
you just add and round up
To find the answer use multiplication. 87% as a decimal equals 0.87 (87 divided by 100). Then multiply 0.87 by 900. Your answer should be $783.

Explanation:
The notation 
or means to move any point (x,y) along the vector <-3,5>. Put another way, it says to shift (x,y) three units to the left and five units up. The x portion deals with left or right shifting, the y portion deals with up or down shifting. Since the x portion is negative, we go in the negative direction on the x axis. Y being positive means we move up rather than down.
This all means we end up with the translation rule
