Answer:
![\$63,163.16](https://tex.z-dn.net/?f=%5C%2463%2C163.16)
Step-by-step explanation:
we know that
The equation of a exponential growth function is equal to
![y=a(1+r)^x](https://tex.z-dn.net/?f=y%3Da%281%2Br%29%5Ex)
where
y is the average annual salary
x is the number of years
r is the rate of change
a is the initial value
In this problem we have
![a=58,353\\r=2\%=2/100=0.02](https://tex.z-dn.net/?f=a%3D58%2C353%5C%5Cr%3D2%5C%25%3D2%2F100%3D0.02)
substitute
![y=58,353(1+0.02)^x](https://tex.z-dn.net/?f=y%3D58%2C353%281%2B0.02%29%5Ex)
![y=58,353(1.02)^x](https://tex.z-dn.net/?f=y%3D58%2C353%281.02%29%5Ex)
For x=4 years
![y=58,353(1.02)^4=\$63,163.16](https://tex.z-dn.net/?f=y%3D58%2C353%281.02%29%5E4%3D%5C%2463%2C163.16)
15 x 1.59 = 23.85
Her order is between 20 euros and 34.99 euros. Therefore, she gets 2.5% discount.
2.5 x 23.85/ 100 = 0.60
That means she gets approximately 60 cents off her order.
Answer:
9 feet
Step-by-step explanation:
The given is 30-60-90 special triangle with the side lengths as follows
x-x√(3- and 2x
The side length that sees 90 degrees (hypotenuse) is 18 which means x = 9
then the side length that sees 30 degrees is 9 as well
To make sure we don't have negatives under the square root, we specify that
![x \ge 0](https://tex.z-dn.net/?f=x%20%5Cge%200)
(x is greater than or equal to 0). We'll use this fact later on
--------------------------------------------
Start with the given inequality
![\sqrt{x} \le 7](https://tex.z-dn.net/?f=%5Csqrt%7Bx%7D%20%5Cle%207)
and square both sides to get
![x \le 49](https://tex.z-dn.net/?f=x%20%5Cle%2049)
. Couple this with the fact that
![x \ge 0](https://tex.z-dn.net/?f=x%20%5Cge%200)
means we have this compound inequality
![0 \le x \le 49](https://tex.z-dn.net/?f=0%20%5Cle%20x%20%5Cle%2049)
What does this mean? It means that we can pick any value from 0 to 49 (including both endpoints) and it will be a solution to the inequality. This applies to the values
