Answer:
B
y = 3 cos (pi/12x - pi/4) + 17
Step-by-step explanation:
First find the average temperature which is 20 + 14/2 = 17
Find the amplitude
20 - 17 = 3
This means that that at noon, the shift is 3hrs past
the best equation that represents this scenario is 
Answer:
r = 1/pt.
Step-by-step explanation:
1 = prt
Divide both sides of the formula by pt:
`1 / pt = r.

Step-by-step explanation:
Answer:
On the science test the point ( 0 , 424 ) the intercepts is bigger
Step-by-step explanation:
The relation hours spend vs science test score is
y = 6.5*x + 424
And the relation hours spend vs Maths test score is
y = 7.2*x + 34.7
Making x = 0 ( student does not study at all ) we get:
For science score test woul be
y = 0 + 424
In case of maths
y = 0 + 34.7
That mean student without studying will get better score in science.
The point ( 0 , 424) ( science ) represents the interception with y axis
in Maths case such point is ( 0 . 34.7)
