2. Find (w2 + 1)(w3 - W+1).

12345 [234]

Answer:

$w^{5} + w^{2} - w + 1$

Step-by-step explanation:

We have to find the simplified expression of $(w^{2} + 1) (w^{3} - w + 1)$ .

Now, we have to multiply each term using the distributive property of multiplication.

So, $(w^{2} + 1) (w^{3} - w + 1)$

= $w^{2} \times (w^{3} - w + 1) + 1 \times (w^{3} - w + 1)$

= $(w^{5} - w^{3} + w^{2} ) + (w^{3} - w + 1)$

= $w^{5} + w^{2} - w + 1$ (Answer)

A wheel spins at 300 revolutions per minute. What is the angular velocity of the wheel, in radians per second? Round the answer

Ostrovityanka [42]

well, this is just a matter of simple unit conversion, so let's recall that one revolution on a circle is just one-go-around, radians wise that'll be 2π, and we also know that 1 minute has 60 seconds, let's use those values for our product.

$\cfrac{300~~\begin{matrix} r \\[-0.7em]\cline{1-1}\\[-5pt]\end{matrix}~~ }{~~\begin{matrix} min \\[-0.7em]\cline{1-1}\\[-5pt]\end{matrix}~~ }\cdot \cfrac{2\pi ~rad}{~~\begin{matrix} r \\[-0.7em]\cline{1-1}\\[-5pt]\end{matrix}~~ }\cdot \cfrac{~~\begin{matrix} min \\[-0.7em]\cline{1-1}\\[-5pt]\end{matrix}~~ }{60secs}\implies \cfrac{(300)(2\pi )rad}{60secs}\implies 10\pi ~\frac{rad}{secs}\approx 31.42~\frac{rad}{secs}$

A=? b=? C =? Can someone tell me the answer please

beks73 [17]

Answer:

Below.

Step-by-step explanation:

a = 37 degrees ( vertical angle to 37 )

c = 180 - 37 = 143 degrees (adjacent angles add up to 180).

b = 180 - 37 - 109 = 34 degrees (angles in a triangle sum to 180 degrees).
