Answer:
6(2a+4)-4(3a-4)= (12a+24) +(-12a+16) = 40
d = 16.76 inches
Step-by-step explanation:
We can extend the definition of the Pythagorean theorem to 3-dimensions:
![d = \sqrt{ {x}^{2} + {y}^{2} + {z}^{2} }](https://tex.z-dn.net/?f=d%20%3D%20%20%5Csqrt%7B%20%7Bx%7D%5E%7B2%7D%20%2B%20%20%7By%7D%5E%7B2%7D%20%20%2B%20%20%7Bz%7D%5E%7B2%7D%20%20%7D%20)
Let x = 10 in
y = 10 in
z = 9 in
![d = \sqrt{ {(10)}^{2} + {(10)}^{2} + {(9)}^{2} }](https://tex.z-dn.net/?f=d%20%3D%20%20%5Csqrt%7B%20%7B%2810%29%7D%5E%7B2%7D%20%2B%20%20%7B%2810%29%7D%5E%7B2%7D%20%20%2B%20%20%7B%289%29%7D%5E%7B2%7D%20%20%7D%20)
![d = \sqrt{281} = 16.76 \: in](https://tex.z-dn.net/?f=d%20%3D%20%20%5Csqrt%7B281%7D%20%20%3D%2016.76%20%5C%3A%20in)
Answer: This question is confusing because I can't come up with a whole answer because I don't see a way to get to it no matter how many different ways I try to solve it ;-; The closest I got was $267 with 10 tickets and the fee
Step-by-step explanation:
<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;
![f(7)=19,000 \cdot 0.96 ^7](https://tex.z-dn.net/?f=f%287%29%3D19%2C000%20%5Ccdot%200.96%20%5E7)
![f(7)=19,000 \cdot 0.7514474781](https://tex.z-dn.net/?f=f%287%29%3D19%2C000%20%5Ccdot%200.7514474781)
![f(7)=14277.502](https://tex.z-dn.net/?f=f%287%29%3D14277.502)
Rounding off to the nearest dollar, we get;
![f(7)=14278](https://tex.z-dn.net/?f=f%287%29%3D14278)
Thus, the approximate value of Mark's car after 7 years is $14278.
Hence, Option a is the correct answer.
