Answer:

The equation in standard form is:

Rx+Py = -PR

Step-by-step explanation:

The slope-intercept form of the line equation

$y = mx+b$

where

m is the slope

b is the y-intercept

Given

The y-intercept (0, -R)

The x-intercept (−P, 0)

Finding the slope between (0, -R) and (−P, 0)

$\mathrm{Slope}=\frac{y_2-y_1}{x_2-x_1}$

$\left(x_1,\:y_1\right)=\left(0,\:-R\right),\:\left(x_2,\:y_2\right)=\left(-P,\:0\right)$

$m=\frac{0-\left(-R\right)}{-P-0}$

$m=-\frac{R}{P}$

Thus, the slope between (0, -R) and (−P, 0) is:

$m=-\frac{R}{P}$

We know that the value of the y-intercept can be determined by setting x = 0, and determining the corresponding value of y.

We are given the y-intercept point (0, −R).

Thus, y-intercept b = -R

so substituting b = -R and $m=-\frac{R}{P}$ in the slope-intercept form to determine the line of the equation

$y = mx+b$

$y=-\frac{R}{P}x\:+\:\left(-R\right)$

$y=-\frac{R}{P}x\:-R$

So, the slope-intercept form of the line equation is:

$y=-\frac{R}{P}x\:-R$

Converting the slope-intercept form of the line equation into standard form

As we know that the equation in the standard form is

Ax+By=C

where x and y are variables and A, B and C are constants

$y=-\frac{R}{P}x\:-R$

so converting into standard form

Multiply the equation by P

Py = -Rx - PR

Add -Rx to both sides

Rx+Py = -Rx - PR + -Rx

Rx+Py = -PR

Therefore, the equation in standard form is:

Rx+Py = -PR

Help me with this please!!!!!!!!!!!!!!!!!!!!!

Andrej [43]

Answer:

y = 2 units

Step-by-step explanation:

We can solve this in 2 ways, both ways would give the same answer:

#1) Sin(45) = $\frac{\sqrt{2} }{y}$

=> Sin(45) * y = $\sqrt{2}$

=> y = $\frac{\sqrt{2} }{Sin(45)}$

=> y = 2

#2) Cos(45) = $\frac{\sqrt{2} }{y}$

=> Cos(45) * y = $\sqrt{2}$

=> y = $\frac{\sqrt{2} }{Cos(45)}$

=> y = 2

Hope this helps!

Example

katen-ka-za [31]

Answer:

The playground is 160ft by 360ft.

The model is 4in by 9in

First, 1ft = 12 inches.

Then the measures of the playground, in inches, is:

160*12in = 1920 in

360*12in = 4320in

The playground is 1920in by 4320in.

Then, the ratios between the measures of the playground and the model are:

1920in/4in = 480

4320in/9in = 480

This means that each inch in the model, represents 480 inches in the actual playground.

If f1) = 160 and f(n +1) =-2fn), what is f4)?

Harrizon [31]

Answer:

$f(4) = 1280$

Step-by-step explanation:

Given

$f(1)= 160$

$f(n+1) = 2f(n)$

Required

Determine f(4)

Take n as 3:

$f(n+1) = 2f(n)$ becomes

$f(3+1) = 2f(3)$

$f(4) = 2f(3)$

We need to get f(3).

Take n as 2

$f(n+1) = 2f(n)$ becomes

$f(2+1) = 2f(2)$

$f(3) = 2f(2)$

We need to get f(2).

Take n as 1

$f(n+1) = 2f(n)$ becomes

$f(1+1) = 2f(1)$

$f(2) = 2f(1)$

Substitute 160 for f(1)

$f(2) = 2 * 160$

$f(2) = 320$

Recall that:

$f(3) = 2f(2)$

$f(3) = 2 * 320$

$f(3) = 640$

Recall that:

$f(4) = 2f(3)$

$f(4) = 2 * 640$

$f(4) = 1280$
