I want to learn how to solve a slope problem
mina [271]
The slope (or average rate of change) formula is: m= \frac{ y_{2}- y_{1}  }{ x_{2}- x_{1}  }. It is easy to remember as "slope is easy and fun, rise over run" where the y-values of the 2 points would be the "rise" and the x-values of the 2 points would be the "run" So with two points, you label one point as ( x_{1},  y_{1}) and the other as ( x_{2},  y_{2}). Then you insert these points into the slope formula (m represents slope). So, m= \frac{6-1}{-3-5} where (-3,6) is x2 and y2 and (5,1) is x1 and y1. It would simplify to m= \frac{5}{-8}.

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

The ratio of Kailyn's money to Nathan's money is 4:9. If Nathan has $45, how much do
natita [175]

Answer:

<h2>$65</h2>

Step-by-step explanation:

Step one:

we are told that the ratio of Kailyn's money to Nathan's money is

4:9,

Nathan has $45, let Kailyn's money be x

therefore

4/9=x/45

cross multiply we have

9x=45*4

9x=180

divide both sides by 9

x=180/9

x=20

Kailyn's money is $20

Together they have =20+45= $65

Two runners in a marathon determine that the angles of elevation of a news helicopter are 39.5 degrees and 42 degrees. If the he
Liula [17]
See the attached figure to understand the problem

we know that
tan 42°=1950/BO---------> BO=1950/tan 42°-------> BO=2165.69 ft

tan 39.5°=1950/AO---------> AO=1950/tan 39.5°-------> AO=2365.54 ft

AB=AO-BO--------> AB=2365.54 ft-2165.69 ft-------> AB=199.85 ft

the answer is
The runners are 199.85 feet apart
