Answer:

Option A. 1 mile per minute.

Step-by-step explanation:

Brandon has traveled after the specified period of time. The table shows his covered distance in a specific time.

Minutes 0 5 10 15 20 25

Miles 0 3 7 12 17 21

In this question we have to calculate speed per minute in between 15 and 20 minutes.

As we can see in the table from 15 to 20 minutes, he traveled :

17 - 12 = 5 miles Time taken = 20 - 15 = 5 minutes

Speed = $\frac{distance}{time}$

S = $\frac{5}{5}$ = 1 mile per minute.

Option A) 1 mile per minute

What is $112 in 8 hours

never [62]

Answer:

A unit rate must have a denominator of one:

n/1

So you would get n by dividing 112 by 8: 112 divided by 8 = 14 so n = 14.

14/1 or $14 p/ hr

Solve x'=5t(sqrt(x)) x(0)=1

LekaFEV [45]

Answer:

$2\sqrt{x}=\frac{5t^2}{2}+2$

Step-by-step explanation:

Given: $\frac{\mathrm{d} x}{\mathrm{d} t}=5t\sqrt{x}\,,\, x(0)=1$

Solution:

A differential equation is said to be separable if it can be written separately as functions of two variables.

Given equation is separable.

We can write this equation as follows:

$\frac{dx}{\sqrt{x}}=5t\,dt$

On integrating both sides, we get

$\int \frac{dx}{\sqrt{x}}=\int 5t\,dt$

Formulae Used:

$\int \frac{1}{\sqrt{x}}=2\sqrt{x}\,\,,\,\,\int t\,dt=\frac{t^2}{2}$

So, we get solution as $2\sqrt{x}=\frac{5t^2}{2}+C$

Applying condition: x(0) = 1, we get $C=2$

Therefore, $2\sqrt{x}=\frac{5t^2}{2}+2$
