I haven't done these problems in a really long time, so there's a chance that my answer might be wrong. I hypothesize that the correct answer is C.
Answer:
She wrapped 5 presents
Step-by-step explanation:
She used 2cm to wrap each present
8cm = 4x
x is the amount of presents
divide by 4
x= 2 cm
Given 10 cm, divide by 2 to determine amount of x, or presents
Sqrt of 125
10^2 +b^2= 15^2
100 +b^2=225
B^2=125
No perfect square for 125 so leave it in radical form
153 x 7.14 = 1092.42
so every year she gets $1092.42
so times that by 6 and the answer is $6554.52
Answer:
B
Step-by-step explanation:
The line on the left has a negative slope of - 1 and a y- intercept at 2
The line has a closed circle at x = 1, thus
- x + 2 for x ≤ 1
The line on the right has a positive slope of 1 and a projected y- intercept at 1
The start of the line has an open circle at x = 1 indicating it cannot equal 1, thus
x + 1 for x > 1
The definition for the function is B
