Answer:
A) k(x)
Step-by-step explanation:
An inverse function does the opposite to the function.
For example, if the function was "+2" then the inverse would be "-2", or if the function was "×2" the inverse would be "÷2".
An <u>inverse function</u> is a <u>reflection of the function in the line y = x</u>
Therefore (x, y) → (y, x)
(-8, 2) → (2, -8)
(-4, 3) → (3, -4)
(0, 4) → (4, 0)
(4, 5) → (5, 4)
(8, 6) → (6, 8)
Therefore, the function k(x) could be an inverse of function g(x).
Answer:
11.x=16 12.x=37
Step-by-step explanation:
11.
20^2-12^2=x^2
256=x^2
x=√256
x=16
12.
13^2-5^2=y^2
144=y^2
y=12
/
y^2+35^2=x^2
12^2+35^2=x^2
1369=x^2
x=37
Answer:
A, it will decrease by 90.
Step-by-step explanation:
If the number is 92,320 and you interchange 2 and 3, you would get 92,230. 320-230 equals 90, therefore giving you the answer.
Answer:
25.7 is how much his luggage weighs.
Step-by-step explanation:
Answer:
7.8. 10 ^ 3 m / s
Step-by-step explanation:
The computation of the average speed in m/s is shown below:
The average speed equation is
= ΔS ÷ Δt;
As We know that
an entire revolution would be40,000 km
and a satellite takes 85 minutes to complete a revolution,
So,
ΔS = 40,000 km = 40,000,000 m
Δt = 85 min = 5 100 s
Now the average speed is
= 40 000 000 ÷ 5 ÷ 5 100
= 7843.14 m / s
= 7.8. 10 ^ 3 m / s
