(4,7) ; m=-2 in point slope form & slope intercept please

Snezhnost [94]

$\huge\boxed{y - 7 = -2(x - 4)}$

$\huge\boxed{y = -2x + 15}$

<h3>Point-Slope Form</h3>

Point-slope form is $y - y_1 = m(x - x_1)$ , where $(x_1, y_1)$ is a point on the line and $m$ is the slope of the line.

Substitute in the values. $\boxed{y - 7 = -2(x - 4)}$

<h3>Slope-Intercept Form</h3>

Slope-intercept form is $y=mx+b$ , where $m$ is the slope of the line and $b$ is the y-intercept of the line.

We need to convert the equation into slope-intercept form.

Distribute the $-2$ to the $(x-4)$ . $y - 7 = -2x + 8$

Add $7$ on both sides. $\boxed{y = -2x + 15}$

Two sides of a triangle have lengths 48 and 32. how long can the third side be

stiv31 [10]

You want all the sides to equal up to 180°.

48 + 32 = 80

180° - 80 = 100

So the 3rd side can be 100.

Hope this Helps!!

A reservoir in the shape of a right cylinder has a height of 84 ft am

liubo4ka [24]

Question:

A reservoir in the shape of a right circular cylinder has a height of 84ft. If it to contain 79,200 L of water, find its radius.

Answer:

$r = 3.26ft$

Step-by-step explanation:

Given

$Volume = 79200L$ ---- V

$Height = 84ft$ --- h

Required

Determine the radius

$Volume = 79200L$

Convert volume to $ft^3$

$Volume = 79200 * 0.0353147ft^3$

$Volume = 2796.9216ft^3$

The volume (V) of a cylinder is:

$V = \pi r^2 h$

Substitute values for volume and height

$2796.9216 = \pi * r^2 * 84$

Divide both sides by 84

$33.2966857143 = \pi * r^2$

Take $\pi$ as 3.14

$33.2966857143 = 3.14 * r^2$

Divide both sides by 3.14

$10.604 = r^2$

$r^2 = 10.604$

Take the square root of both sides

$r = \sqrt{10.604$

$r = 3.26ft$

<em>Hence, the radius is 3.26 ft</em>
