Answer:
neither exponential nor linear
Step-by-step explanation:
A linear relationship will show a common difference between adjacent value. Here, the first differences between the first three values are 5 and 33. They are not the same, so the relation is not linear.
__
An exponential relationship will show first differences that are continuously increasing or decreasing by increasing or decreasing amounts (respectively).
As we showed, the difference between May 28 and May 27 is 33. This is more than the previous difference. However, the difference between May 30 and May 31 is only 28, which is less than a previous difference.
The relation is not exponential.
__
A graph points up the non-linearity of the relation.
Answer: The tangent of the larger acute angle is 4/3 or 1⅓
Step-by-step explanation: if the sides of the right angled triangle are given as 3, 4 and 5 respectively, then the hypotenuse is 5 and the longer of the other two sides is 4. The angle facing the side measuring 4 is your reference angle, and that is the larger of the other two acute angles (see attachment)
Tan X = opposite/hypotenuse
Tan X = 4/3
Tan X = 1⅓
72 percent as a fraction is 72/100 or you could also use 18/25
Calculate total pages:
(216 pages per book)(13 books) = 2,808 total pages
Now divide by pages per day: Irene reads 18 pages a day
2,808 total pages / 18 pages per day = 156 days to read 13 books
To solve this one we need to find 15% of 3400 and then subtract it from 3400
to find percent we multiply so we'll multiply by 0.15
3400 times 0.15=510
3400-510=2890
then actual cost of the couch is $2890
I hope I've helped!
