For the scatter plot on homework:
a) The relationship is that the test score will increase, if the time spent on homework increases.
b) The function is y=8x+40, and what we need to see is what the score will be if someone puts in 3 hours of homework, x=3 in this because it means the time spent on homework:
y=8(3)+40
y=24+40
y=64
c) The score would be 40% if no time was spent doing homework.
For the scatter plot on the rides:
a) y = -7/5x + 17.8
b) Anika worked 17.8 hours on Day 0
c) Decreased by 7/5 in a day.
Hope this helps, have a BLESSED AND WONDERFUL DAY! As well as a great Superbowl Weekend! :-)

Answer:
27π
Step-by-step explanation:
area of circle = πr^2
= π × 6^2
= 36π
36/4
= 9
36 - 9
= 27π units squared
Answer:
Approximately 360.3
Step-by-step explanation:
△ABC, AB = BC and CH is an altitude.
Note in isosceles triangle the two base angle are equal.
And two sides are equal.
CH = 84 cm and m∠HBC = m∠BAC +m∠BCH
So yhe base angle = 50°
The length of tthe hypotenuse , lets cal it x
Sin 50 = 84/x
X = 84/sin 50
109.65 = x
For the The base
109.65²-84²=b²/4
141 = b
Perimeter = 2*109.65 + 141
Perimeter = 360.3
Approximately 360
The answer is x+2 and x-1
