Answer:
n = r - 2.5
Step-by-step explanation:
We have the following data:
7 4.5
8 5.5
10 7.5
12 9.5
Now, what we will do is what happens if we subtract each one:
7 - 4.5 = 2.5
8 - 5.5 = 2.5
10 - 7.5 = 2.5
12 - 9.5 = 2.5
The difference is always kept constant, therefore the equation would be:
n = r - 2.5
Answer:
Step-by-step explanation: is given value in dollars of a stock in t months after it is purchased.
a) Substitute 1 for t
V(12) =
b) Find derivative for V
c) When V(t) = 75
d) As t tends to infinity, exponent being in negative t tends to 0
So V tends to 42(1-0)+36 = 78
Answer:
b. 67
Step-by-step explanation:
In order for the average to be 62, the total of differences from 62 must be zero. The two given numbers have differences of -4 and -1, for a total of -5. In order for the total of differences to be zero, the third number must have a difference from 62 of +5. It must be 62+5 = 67.
Jon's height at his third checkup was 67 inches.
Answer:
11.2ft
Step-by-step explanation:
14 is 2/3 of 21 so the scale factor is 2/3.
16.8x2/3= 11.2
Answer is “A”
Because since we know if we need to find the y is so we need to subtract 11-2.9=8.1
which mean y mean 8.1
