Please show solving

Answers

The inverse function theorem says

$(\mathrm df^(-1))/(\mathrm dx)(16)=\frac1{(\mathrm df)/(\mathrm dx)(f^(-1)(16))}$

We have

$f(x)=x^2+4x-5$

defined on $x>-2$ , for which we get

$f^(-1)(x)=-2+√(x+9)$

and

$f^(-1)(16)=-2+√(16+9)=3$

The derivative of $f(x)$ is

$f'(x)=2x+4$

So we end up with

$(\mathrm df^(-1))/(\mathrm dx)(16)=\frac1{(\mathrm df)/(\mathrm dx)(3)}=\frac1{10}$

A red die is tossed and then a green die is tossed. What is the possibility that the red die shows a six or the green die shows a six?

Answers

The two events are independent of each other.

This means that:

$\text{Pr}(\text{red 6}) = \text{Pr}(\text{green 6})$
$\text{So total probability is: } \text{Pr}(\text{red 6}) + \text{Pr}(\text{green 6}) = (2)/(6) = (1)/(3)$

2x-8=6x-6

2x-6x-8=-6

-4x-8=-6

-4x=-6+8

-4x=2

x=2/-4

simplify

An automobile engineer is revising a design for a conical chamber that was originally specified to be 12 inches long with a circular base diameter of 5.7 inches. In the new design, the chamber is scaled by a factor of 1.5. What is the volume of the revised chamber? Round your answer to two decimal places.

Answers

Volume of a cone = 1/3πr²h
r = 5.7/2 = 2.85
h = 12
Volume of original design =1/3π(2.85)²(12)
= 32.49π
= 102.07.....
Linear scale factor = 1.5 = 3/2
Volumetric scale factor = (3/2)³ = 27/8
Volume of revised design = 102.07..... × 27/8
= 344.487..... ⇒ 344.5 in³
