Answer:

\large\boxed{f^{-1}(x)=h(x)=\dfrac{1}{4}x}

Step-by-step explanation:

f(x)=4x\to y=4x\\\\\text{exchange}\ x\ \text{to}\ y\to x=4y\\\\\text{solve for}\ y:\\\\4y=x\qquad\text{divide both sides by 4}\\\\\dfrac{4y}{4}=\dfrac{x}{4}\\\\y=\dfrac{1}{4}x

Answer: D. h[x]=1/4x

Step-by-step explanation:

f(x) = 4x  or y = 4x

Its inverse is obtained by switching the variables and solving for y.

x = 4y

y = (1/4)x

If a weight hanging on a string of length 5 feet swings through 6° on either side of the vertical, how long is the arc through w
garik1379 [7]

Answer:

  1.047 ft

Step-by-step explanation:

The length of an arc is given by ...

  s = rθ

where s is the arc length, r is the radius, and θ is the central angle in radians. Your arc subtends an angle of 12° = (12·π/180) = π/15 radians. The length of the arc is then ...

  s = (5 ft)(π/15) = π/3 ft ≈ 1.047 ft

What is the greatest prime you must consider to test whether 575 is prime
GuDViN [60]

Hello from MrBillDoesMath!

Answer:  23

Discussion:

We only need to check primes less that the square root of 576, which is about 23.98. As 23 is a prime number, it is the answer to the question.

Another way of looking at this: the primes less than or equal to 23

(23*23 = 529)

2, 3, 5,7,11,13,17,19,23

The greatest prime in the list is 23


Thank you,

MrB
