Answer:

${5}^{3} \times {5}^{x} = {5}^{7} \\ 3 + x = 7 \\ x = 4$

$( {q}^{2} )^{y} = {q}^{6} \\ 2y = 6 \\ y = 3$

${1000}^{m} \div {100}^{n} = {10}^{z} \\ \frac{1000 ^{m} }{ {100}^{n} } = {10}^{z} \\ \\ {10}^{m - n} = {10}^{z}$

Can I have the brainliest please?

A point on the rim of a wheel has a linear speed of 33 cm/s. If the radius of the wheel is 50 cm, what is the angular speed of t

Zigmanuir [339]

Answer:

The angular speed of the wheel in radians per second is 0.66.

Step-by-step explanation:

Recall the following statement:

A linear speed (v) is given by,

$v=\omega \times r$ ...... (1)

Here, $\omega$ represents the angular speed of the wheel and r represents the radius of the wheel.

From the given information:

Linear speed (v) = 33 cm/s

Radius of the wheel (r) = 50 cm

Now to find the angular speed in radian per second.

$33 =50 \times \omega$

Divide both sides by 50.

$0.66 rad/sec= \omega$

Hence, the angular speed of the wheel in radians per second is 0.66.

Z varies jointly with y and the square of x. If x=4 when y=−7 and z=−336, find x when z=36 and y=3.

mario62 [17]

$\bf \qquad \qquad \textit{direct proportional variation}\\\\
\textit{\underline{y} varies directly with \underline{x}}\qquad \qquad y=kx\impliedby 
\begin{array}{llll}
k=constant\ of\\
\qquad variation
\end{array}\\\\
-------------------------------\\\\$

$\bf \textit{z varies jointly with y and the square of x}\qquad z=kyx^2
\\\\\\
\textit{we also know that }
\begin{cases}
x=4\\
y=-7\\
z=-336
\end{cases}\implies -336=k(-7)(4)
\\\\\\
\cfrac{-336}{-28}=k\implies 12=k\qquad \qquad \boxed{z=12yx^2}
\\\\\\
\textit{when z=36 and y=3, what is \underline{x}?}\qquad 36=12(3)x^2
\\\\\\
\cfrac{36}{12\cdot 3}=x^2\implies \sqrt{\cfrac{36}{12\cdot 3}}=x$
