Brainly says you need the following points
- The pattern is min-zero-max-zero-min, which is the pattern for a cosine function of the form y = acos(x) + k, but is reflected over the x-axis (so a < 0).
- The amplitude is |a|, so a = –1 and |a| = 1.
- The midline is exactly between the max and the min, y = (6 + 8)/2 = 7, so k = 7.
- The equation is y = –cos(x) + 7.
8.75 x 10 = 87.50, easiest way to figure out is divide each amount by each answer choice
Step-by-step explanation:
You can prove it by pythegoras use unit and you will get
Ef=gh
And FG=EH
NQS= 30
you just subtract 78-48 to get 30
Answer:
He went to bed when it was 40 celsius
Step-by-step explanation:
.5 degree per minute for 60 minutes
.5*60
30 degrees more
30+10=40 degrees
