Answer:
176.71 in²
Step-by-step explanation:
area = πr²
r is half the diameter so r=15/2=7.5
3.1415 · 7.5² ≈ 176.71 in²
Answer:
Option a is right.
Step-by-step explanation:
Parent funciton is
The new graph is
Since there is no change for x, there is no horizontal shift.
BUt since sign is changed there is a reflection on the line y=0 i.e. x axis.
Also new y is -2x^3 , -2 indicates the vertical shrink by scale factor 1/2
Option a is right
i.e. there is a reflection on x axis also there is a compression of scale factor 2 vertically.
So as there are 9 reds, you know that the total number of counters is 100 (because red probability is 9/100)
so you can work out x by writing an equation.
9 + 3x + x - 5 + 2x = 100
from here you can add up all of the x's and the numbers (so you have 3x+x +2x = 6x)(and for numbers you have 9 and -5, 9 - 5 = 4) so putting these together you have 6x and 4 you get the following:
6x + 4 = 100
take away 4 from both sides
6x = 96
divide both sides by 6
x =96/6 = 16
green is x-5 so if you substitute the result we got for x...
16-5 = 11. so there are 11 greens
therefore the probability would be 11/100 as there are 100 counters overall.
Answer: The second option
When you divide two numbers, the solution is called the quotient. “Increased“ means to add.
