Which represents the inverse of the function f(x) = 4x? h(x) = x + 4 h(x) = x – 4 h(x) = three-quartersx h(x) = one-quarterx

aalyn [17]

Answer:

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

Step-by-step explanation:

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

A cone has a height of 2.5 in. and a radius of 5 in. What is the volume of the cone? (Use 3.14 for Pi. Round the answer to two d

Stells [14]

Answer:

$V =\frac{1}{3} \pi r^2 h$

And replacing we got:

$V = \frac{1}{3} (3.14) (5in)^2 (2.5in) = 65.42 in^3$

And the best option would be:

65.42 Inches cubed

Step-by-step explanation:

For this case we have the following info given:

$h =2.5 in$ represent the height of the cone

$r = 5 in$ represent the radius

And the volume of the cone is given by;

$V =\frac{1}{3} \pi r^2 h$

And replacing we got:

$V = \frac{1}{3} (3.14) (5in)^2 (2.5in) = 65.42 in^3$

And the best option would be:

65.42 Inches cubed
