May someone please help me out with this problem? May you also explain it?
gavmur [86]

Answer:

Step-by-step explanation:

Given function is,

f(x) = \sqrt{x}

If the given function is vertically stretched by a scale factor of \frac{3}{2} Or 1.5,

Transformed function will be,

h(x) = \frac{3}{2}[f(x)]

h(x) = \frac{3}{2}(\sqrt{x})

Further function 'h' is shifted 1 units upwards,

g(x) = h(x) + 1

g(x) = \frac{3}{2}(\sqrt{x} )+1

Domain of the function → x ≥ 0 Or [0, ∞)

Range of the function → y ≥ 1 Or [1, ∞)

Transformations done → Parent function f(x) is vertically stretched by a scale factor of \frac{3}{2} then shifted 1 unit upward.

Mariah needs the circumference of a circular pit in her backyard to be 18.9 meters. She uses a rope tied to a wooden stake to tr
lara31 [8.8K]

Answer: See explanation

Step-by-step explanation:

Your question isn't complete but I'm assuming that you want to calculate the radius.

Circumference of a circle = 2πr

where Circumference = 18.9 meters

Radius = Unknown

π = 3.14

We then put the values into the formula which will be:

C = 2πr

18.9 = 2 × 3.14 × r

18.9 = 6.28r

r = 18.9 / 6.28

r = 3

The radius = 3 meters

Assuming you probably want to get the diameter, we multiply the radius by 2. This will be:

= 2 × 3

= 6 meters
