Answer:

$32$ $or~2^5$

Step-by-step explanation:

→ $(2^3)(2^2)$

$=2^3*2^2$

$=(2*2*2)*(2*2)$

$=2*2*2*2*2$

$=32$

<u><em>You can also put this in another way:</em></u>

<em /> $2^5=2^3*2^2=2^3^+^2=2^5$ <em />

$2^{3}\cdot 2^{2}=2^{3+2}=2^{5}\\\\because\\\\a^{x}\cdot a^{y}=a^{x+y}$

erica would like to bake an 3-pound roast for a family gathering. the cookbook tells her to bake a 6-pound roast for 138 minutes

BabaBlast [244]

We know that we need to bake 6 pound for 138 minutes, then we have the proportion:

$\frac{6}{138}$

Let x be the time we need to bake the 3 pound roast, in this case we have the proportion:

$\frac{3}{x}$

By equating both ratios we have the proportion:

$\frac{3}{x}=\frac{6}{138}$

Now, by simplifying the right side of the proportion we have that:

$\begin{gathered} \frac{3}{x}=\frac{6}{138} \\ \frac{3}{x}=\frac{3}{69} \end{gathered}$

For this proportion to be equal we need that x=69, therefore we need to cook the 3 pound roast for 69 minutes.

Normally I don’t ask for help but I’m very lost on question 4. I know I need to first find the derivative of f(x) but I’m not su

Daniel [21]

Answer:

$\displaystyle f'(\frac{\pi}{4})=2$

Step-by-step explanation:

<u>Trigonometric Derivatives</u>

We have the function

$\displaystyle f(x)=\sin x \csc x-\frac{1}{\tan x}$

We must recall that the sine and the cosecant are reciprocal functions, i.e.:

$\displaystyle \sin x =\frac{1}{\csc x}$

Also, the reciprocal of the tangent is the cotangent:

$\displaystyle \cot x =\frac{1}{\tan x}$

Thus:

$\displaystyle f(x)=1-\cot x$

Now it's easier to take the derivative

$\displaystyle f'(x)=0+\csc^2 x= \csc^2 x$

Evaluating for x=π/4:

$\displaystyle f'(\frac{\pi}{4})= \csc^2 \frac{\pi}{4}$

Since csc π/4= $\sqrt{2}$ :

$\displaystyle f'(\frac{\pi}{4})= \sqrt{2}^2$

$\displaystyle f'(\frac{\pi}{4})=2$

Find the diameter of a cone that has a volume of 104.67 cubic inches and a height of 4 inches. Use 3.14 for pi.

Lady bird [3.3K]

Answer:

Step-by-step explanation:

The volume of a cone is

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

Filling in what we have:

$104.67=\frac{1}{3}(3.14)r^2(4)$ and simplifying a bit:

$104.67=\frac{1}{3}(12.56)r^2$

Multiply both sides by 3 to get:

$314.01=12.56r^2$

Divide both sides by 12.56 to get:

$25.00079618=r^2$ and take the square root of both sides to find the radius:

r = 5

If the radius is 5 and the radius by definition is half the diameter, then the diameter is 10 inches.
