Answer: (13x+8)(13x-8) is the answer
Answer:
length= 3.7 ft.
Step-by-step explanation:
T= (square root of length) * k
1.8 seconds = (square root of 3) * k
k= 1.8 seconds / (square root of 3)
a.) T= (square root of 11) k
substituting k:
T=(square root of 11) * 1.8 seconds / (square of 3)
T= 3.4 seconds
b.) 2 seconds = (square root of length) k
substituting k:
2 seconds =(square root of length) 1.8 seconds / (square root of 3)
Divide the equation by 1.8 seconds / (square root of 3):
2 seconds / [1.8 seconds / (square root of 3)] = (square root of length)
10(square root of 3) / 9 = (square root of length)
square both sides:
100/7 ft= length
length= 3.7 ft.
Hope this helps.
Answer:
why are you digging through skittles 150 times?
One of them can be finding the x intercept which the answer would be x= 5
The inverse of the function is y = 
In order to find this, you must start by switching the y and x values. Once you do this, you can solve for the new y value and that will be in inverse. The work is done for you below.
y = 2x^2 + 2 ---> switch x and y
x = 2y^2 + 2 ---> subtract 2 from both sides
x - 2 = 2y^2 ---> divide both sides by 2
= y^2 ---> take the square root of both sides.
= y
