Step-by-step explanation:
Which pair of functions are inverses of eachother?
Answer:
D
Step-by-step explanation:
A.
y= 6x³
to find the inverse substitute x for y and y for x and solve for y
x= 6y³ ; divide both sides by 6
x/6 =y³ ; cube root both sides
(∛x)/ ∛6 = y
so (∛x)/6 and 6x³ are NOT inverse of each other
B
y= (x+2)/5
x= (y+2)/5; multiply by 5
5x = y+2; subtract 2
y= 5x-2 NOT corect
C
y = 5x-6
x= 5y-6; add 6 to both sides
x+6 = 5y ; divided by 5 both sides
y = (x+6)/5 is NOT correct
D
y=7x -2
x= 7y-2
x+2 = 7y , (x+2) /7 = y so IS correct

Marcie Bruno received a 4.2% merit increase and a 2.75% cost-of-living increase
after her quarterly review. Her new weekly salary was $788.92. What was her
weekly salary prior to the increases?
Answer:
734.1
Step-by-step explanation:
100%=788.92
4.2%=33.13
2.75%=21.69
33.13+21.69=54.82
788.92-54.84=734.1
A creature on the moon throws a rock off a cliff. The height of the rock above the surface of the moon, in meters, t seconds after it is thrown is given by h(t) = −t 2 + 8t + 10. When does the rock hit the surface of the moon?
Answer:
9.099 seconds
Step-by-step explanation:
The rock hits the surface of the moon when is t is 0.
[tex]-t^2 + 8t + 10 = 0\\t^2 - 8t - 10 = 0[/tex]
Use the quadratic formula
t = -1.099 and 9.099
Since time can't be negative, the answer is t = 9.099
What is the value of x2?

70
Answer: 14
Step-by-step explanation:
110 + 110 + 70 + 5x= 360 ( total number of angles in a quadrilateral is 360 degrees)
290+5x= 360
5x= 360 - 290= 70
x= 70/5= 14

The distance Jane jogs in 20 minutes is 8 miles. At this rate, how many miles will he run in 60 minutes?
Answer: the answer is 24 miles
Step-by-step explanation:
Answer:
24 miles
Step-by-step explanation:
the ratio is 20:8
If we wanna find the ratio for 60 mins, you have to multiply both sides by three.
Then, we get 20/8 = 60/24
So, Jane jogged 24 miles in sixty minutes

Divide 2m in the ratio 9-1
Answer:
Step-by-step explanation:
First, add up the two numbers in the ratio to get 8. Next divide the total amount by 8, i.e. divide £40 by 8 to get £5. £5 is the amount of each 'unit' in the ratio.
To calculate the ratio of an amount we divide the amount by the total number of parts in the ratio and then multiply this answer by the original ratio. We want to work out $20 shared in the ratio of 1:3.
