Which one do you need help with?
Answer:
We know that ,

So ,

we can add 2 pi to it since there will be no change in the value
Also,

Answer : Option B
Answer:
12
Step-by-step explanation:
There are 4 circles, 6 stars. The ratio is 4/6 = 2/3
if there is 8 circles in order to get the same ratio 8/x = 2/3 => x = 12
Answer:
D
Step-by-step explanation:
the equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
here m = - 2 , then
y = - 2x + c ← is the partial equation
to find c substitute (3, - 2 ) into the partial equation
- 2 = - 6 + c ⇒ c = - 2 + 6 = 4
y = - 2x + 4 ← equation of line in slope- intercept form
Answer:
9s^2 + 17g - 12
Explanation:
(basically combine like terms)
the s^2 are like terms, so that would get you 18s^2 - 9s^2 = 9s^2
then the g’s are like terms,
15g + 2g = 17g
then the -12 is all on its own
if you put it all together:
9s^2 + 17g - 12
