Answer: 10
Step-by-step explanation:
Use Pythagorean theorem!
a^2+b^2=c^2
6^2+8^2=c^2
64+36=c^2
100=c^2
Take the square root of 100 and you get c=10
Answer:
1/2
Step-by-step explanation:
When given two points, we can find the slope by
m = (y2-y1)/(x2-x1)
= (1-0)/(-3- -5)
= (1-0) / (-3+5)
= 1/2
<u>Given</u>:
The given function
which models the value of Mark’s car, where x represents the number of years since he purchased the car.
We need to determine the approximate value of Mark's car after 7 years.
<u>Value of the car:</u>
The value of the car after 7 years can be determined by substituting x = 7 in the function
, we get;



Rounding off to the nearest dollar, we get;

Thus, the approximate value of Mark's car after 7 years is $14278.
Hence, Option a is the correct answer.
Answer: a = 0.81
So yeah, that is the answer.
