<u>Answer</u>:
![f^{-1}(x) = \sqrt[5]{\frac{x+7}{9} -10}](https://tex.z-dn.net/?f=f%5E%7B-1%7D%28x%29%20%3D%20%5Csqrt%5B5%5D%7B%5Cfrac%7Bx%2B7%7D%7B9%7D%20-10%7D)
<u>Explanation</u>:
given : f(x) = 9( 
+ 10 ) - 7
replace x and y with each other.
- x = 9(
+ 10 ) - 7
solve for y
- x + 7 = 9( + 10 )
- =
- 10
- y =
![\sqrt[5]{\frac{x+7}{9} -10}](https://tex.z-dn.net/?f=%5Csqrt%5B5%5D%7B%5Cfrac%7Bx%2B7%7D%7B9%7D%20-10%7D)
Therefore,
Answer:
c = 22.8 miles/hr
Step-by-step explanation:
The ship A sails north at the rate of 14 mile per hour , it represent the opposite side of a triangle. Ship B start at the same point and move east at the rate of 18 miles per hour, it represent the adjacent side.
The other rate telling you how fast the distance between them are changing can be computed using the Pythagorean theorem, since the change in time is 1 hour. From 12 noon to 1 pm.
c = ?
a = 14
b = 18
c² = a² + b²
c² = 14² + 18²
c² = 196 + 324
c² = 520
c = √520
c = 22.803508502
c = 22.8 miles/hr
A)
rate of change from A to B = 48-0 / 1-0 = 48/1 = 48 ( feet per second)
rate of change from B to C = 64 -48 / 2-1 = 16 /1 = 16 ( feet per second)
B) the rate from A to B is greater. This tells me gravity starting acting on the rocket and started slowing it down
When simplifying you need to be able to divide both the top and bottom number in the fraction by one of their factors. A number will be fully simplified when they become a prime number or have one as the numerator.
Answer:
<h2> B and C are not independent events </h2>
Step-by-step explanation:
This is a probability question, basically on independent events.
B and C are said to be independent if the occurrence of either event does not affect the occurrence of the other.
And now considering the fact that C will always present a head any way anyhow, the occurrence
of C will affect the outcome of B and C.
<em>Hence B and C are not independent events</em>
