Answer:

The Cheetah's initial speed is 19.4 miles per hour

Step-by-step explanation:

Since the Cheetah is initially running and then gradually increases its speed by 50.6 miles per hour to reach a top speed of 70 miles per hour, let the Cheetah's initial speed be u.

Also, let the increase in the Cheetah's speed be Δu and let v be the Cheetah's final speed.

Now, the final speed, v = initial speed, u + change in speed, Δu

So, v = u + Δu

So, the Cheetah's initial speed is u = v - Δu

Now, v = 70 mi/h and Δu = 50.6 mi/h

Substituting v and Δu into the equation, we have

u = v - Δu

u = 70 mi/h - 50.6 mi/h

u = 19.4 mi/h

So, the Cheetah's initial speed is 19.4 miles per hour

Answer:

B. Yes! Jason has printed 73/100 of the posters needed.

Step-by-step explanation:

Which equation is equivalent to log Subscript 3 Baseline (x 5) = 2?.
grin007 [14]

The equivalent equation is x - 4 = 0.

<h2>Linear system</h2>

It is a system of an equation in which the highest power of the variable is always 1. A one-dimension figure that has no width. It is a combination of infinite points side by side.

<h3>Simplification</h3>

Simplification is to make something easier to do or understand and to make something less complicated.

Given

The expression is \rm log_3(x + 5) = 2.

<h3>To find </h3>

The equivalent equation.

<h3>How to find the equivalent equation.</h3>

The expression is \rm log_3(x + 5) = 2.

On simplifying. we get

\begin{aligned} \rm log_3(x + 5) &= 2\\x + 5 &= 3^2\\x + 5 &= 9 \\x  &= 9 - 5\\x &= 4\\x - 4 &= 0\\\end{aligned}

The equivalent equation is x - 4 = 0.

More about the linear system link is given below.

In a free-fall experiment, an object is dropped from a height of h = 400 feet. A camera on the ground 500 ft from the point of i
PilotLPTM [1.2K]
Hmmm the object, is at rest, when dropped, so it has a velocity of 0 ft/s

the only force acting on the object, is gravity, using feet will then be -32ft/s²,


was wondering myself on -32 or 32.. but anyhow... we'll settle for the negative value, since it seems to be just a bit of convention issues

so, we'll do the integral to get v(t) then

\bf \displaystyle \int -32\cdot dt\implies -32t+C&#10;\\\\\\&#10;\textit{object moves from \underline{rest}, so velocity is 0 at 0secs}&#10;\\\\\\&#10;-32(0)+C=0\implies C=0\implies \boxed{v(t)=-32t}&#10;\\\\\\&#10;\textit{now to get the positional s(t)}&#10;\\\\\\&#10;\displaystyle \int -32t\cdot dt\implies -16t^2+C&#10;\\\\\\&#10;\textit{the initial \underline{position} was 400ft away at 0secs}&#10;\\\\\\&#10;-16(0)^2+C=400\implies C=400\implies \boxed{s(t)=-16t^2+400}

when will it reach the ground level? let's set s(t) = 0

\bf s(t)=-16t^2+400\implies 0=-16t^2+400\implies \cfrac{-400}{-16}=t^2&#10;\\\\\\&#10;25=t^2\implies \boxed{5=t}
