to vertically shrink a function by a factor of c, multiply the whole function by c
f(x) vertically shrunk by a factor of c would be cf(x)
so f(x)=-3|x-4| vertically shrunk by a factor of 1/2 would be
These three vectors are linearly <u>dependent</u> (details are in the attachment).
Answer:
length = 20
width = 7
Step-by-step explanation:
Perimeter of a rectangle is
P = 2(l+w)
54 = 2( 3x+2 + 2x-5)
Combine like terms
54 = 2( 5x -3)
Divide each side by 2
54/2 = 5x-3
27 = 5x-3
Add 3 to each side
27+3 = 5x-3+3
30 = 5x
Divide by 5
30/5 = 5x/5
6 =x
3x+2 = 3(6)+2 = 18+2 = 20
2x-5 = 2(6)-2 =12-5 =7
My answer would be B 19
19 days is what they claimed but the sample is outside of the 95% confidence interval so
19 x 95% = 19.95
Below this value, 19.95 is the probable mean number of days that the company's air fresheners last. 15,17, and 19 can be the mean number of days.
I think its B. correct me if wrong
