Answer:
C.)9
Step-by-step explanation:
You add up all your data to get 54 and divide by the amount of numbers you had in the data which was 6. So if you divide 54 by 6 you get 9.
Answer:
central angle =23.88°
Step-by-step explanation:
Given:Arc length =10ft
radius= 24ft
To find : central angle
Formula: Arc length = 2πr.
°
⇒
=
⇒

Answer:
From the most right side it's 2^0 which is 1. The other ones are 2^4 and 2^3, So 16+8+1=25
F(x) = k*x^2
You can find k using only the first point.
28 = k*2^2
7 = k
The constant of variation is 7.
Answer:
a= -1
B
Step-by-step explanation:
My opinion:
the slope m = (y2 - y1) / (x2 - x1)
slope m is -5
y2 is 7
y1 is 2
x2 is -2
x1 is a
so the equation will be
-5 = (7 - 2) / (-2 -a )
10 + 5a = 5
5a = -5
a = -1
Then you can plug the value a = -1 into the equation of the slope m to double check it.
