An object travels around a circle of radius r with constant speed. If s is the distance traveled in time t around the circle and

Alex

Answer with Step-by-step explanation:

We are given that

Radius of circle=r

Total distance traveled =s

Time=t

Central angle= $\theta$ rad

We know that

Linear speed,v= $\frac{distance}{time}$

Using the formula

Therefore, v= $\frac{s}{t}$

Angular speed, $\omega=\frac{Angular\;displacement}{time}$

By using the formula

$\omega=\frac{\theta}{t}$ rad/s

Rewrite the quadratic function in intercept or factored form<br> y=-40x+2x^2-2x

poizon [28]

Answer:

y = 2x(x - 21)

Step-by-step explanation:

The given quadratic function y = -40x + 2x^2 - 2x

This can be rearranged as

y = 2x^2 - 2x - 40x

Here the Greatest Common Factor is 2x, we can take it out and write the remaining term in parenthesis.

y = 2x(x - 1 -20)

y = 2x(x - 21)

That's the answer.

Hope this will helpful.

Thank you.

If f(x)=x2-2x-8 and g(x)=1/4x-1 for which value of x is f(x)=g(x)

fomenos

$f(x)=x^2-2x-8;\ g(x)=\dfrac{1}{4}x-1\\\\f(x)=g(x)\iff x^2-2x-8=\dfrac{1}{4}x-1\qquad\text{multiply both sides by 4}\\\\4x^2-8x-32=x-4\qquad\text{subtract x from both sides}\\\\4x^2-9x-32=-4\qquad\text{add 4 to both sides}\\\\4x^2-9x-28=0\\\\4x^2-16x+7x-28=0\\\\4x(x-4)+7(x-4)=0\\\\(x-4)(4x+7)=0\iff x-4=0\ \vee\ 4x+7=0\\\\x=4\ \vee\ 4x=-7\\\\\boxed{x=4\ \vee\ x=-\dfrac{7}{4}}$
