For f(x) = 4x +1 and g(x) = x2 - 5, find (g/f) (x).

Softa [21]

Answer:

$\left(g/f\right)\left(x\right)=\frac{x}{4}-\frac{1}{16}-\frac{79}{16\left(4x+1\right)}$

Step-by-step explanation:

$f(x)=4x+1$

$g\left(x\right)=x^2\:-\:5$

(g/f)(x) = g(x) / f(x)

$=\:\frac{x^2\:-\:5}{4x+1}\:\:\:\:\:\:$

$=\frac{x}{4}+\frac{-\frac{x}{4}-5}{4x+1}$

$=\frac{x}{4}-\frac{1}{16}+\frac{-\frac{79}{16}}{4x+1}$

$=\frac{x}{4}-\frac{1}{16}-\frac{79}{16\left(4x+1\right)}$

Therefore,

$\left(g/f\right)\left(x\right)=\frac{x}{4}-\frac{1}{16}-\frac{79}{16\left(4x+1\right)}$

What is the exact volume of the cylinder?

enyata [817]

Answer:

Step-by-step explanation:

The formula for the volume of a cylinder is V = πr²h.

Here, r = 5cm, and h = 15 cm, and so the volume is:

V = πr²h = π(5 cm)²(15 cm), or:

V = π(25 cm²)(15 cm) = 375π cm³, or approximately 1170 cm³

Answer:

$7x + 3y- 2+6x-1+y^2 = y^2+ 3y+13x- 3$

Step-by-step explanation:

Given

$7x + 3y- 2+6x-1+y^2$

Required

Simplify

Start by collecting like terms

$7x + 3y- 2+6x-1+y^2 = y^2+ 3y+7x +6x- 2-1$

Simplify like terms

$7x + 3y- 2+6x-1+y^2 = y^2+ 3y+13x- 3$

15% of what number is 9?

Sholpan [36]

Answer:

x=60

Step-by-step explanation:

We have, 15% × x = 9

or,

100

× x = 9

Multiplying both sides by 100 and dividing both sides by 15,

we have x = 9 ×

100

x = 60

If you are using a calculator, simply enter 9×100÷15, which will give you the answer.
