The slope is 4
The y-intercept is 1
1. and 2. is the same question, so the answer to both is <u>direct variation</u>
3. <u>Direct</u> <u>variation</u>
4. <u>Inverse</u> <u>variation</u>
5. I believe it is <u>Inverse</u>, but I'm not 100% certain
Answer:
8: 90 degrees, 9: 165 degrees, 6: 81 degrees, 7: angles in the same segment are equal
Step-by-step explanation:
For question 8:
Notice how the line AB just barely touches the edge of the circle. We call this kind of line a tangent. The point O is at the center of the circle so the line OB is a radius. The angle between a tangent and a radius is always 90 degrees, so ABO is 90 degrees.
For question 9:
By the exact same logic as 8, ACO is also 90 degrees. The sum of interior angles in a 4 sided shape (a quadrilateral) is always 360 degrees. This means that 15 + 90 + 90 + x = 360 = 195 + x so x = 360 - 195 = 165
For question 6/7:
We use the theorem that the angles in the same segment are equal. This means that a is 81 degrees.
Answer:
P = $ 144.99
Step-by-step explanation:
Given data:
cost of home entertainment center is $2665
duration of deferred payment plan is 18 month
interest rate is 24.36%
Total amount to be paid is 
A = 3695.88
From the information in the questioon this amount is to be paid in 3 year . Thus we have
Monthly payment is =
p = monthly payment
Pv = present value = 3695.88
r =rate per period 
n = number of period 
plugging all value in the above formula
P = $ 144.99
The answer is that it is a statistic
