Answer:

False

Step-by-step explanation:

the equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y-intercept )

here m = - $\frac{1}{4}$ , hence

y = - $\frac{1}{4}$ x + c ← is the partial equation

to find c substitute (- 3, 5) into the partial equation

5 = $\frac{3}{4}$ + c ⇒ c = $\frac{17}{4}$

y = - $\frac{1}{4}$ x + $\frac{17}{4}$ ← equation of line

What is the slope of a line that contains the two points (0, 3) and (4, 5)?

Anika [276]

The formula for slope is (y2 -- y1) / (x2 -- x1).

(0,3) (4,5)

5 - 4 = 1

3 - 0 = 3

So the slope is 1/3.

Hope this Helps!!

Answer:

264 ft³

Step-by-step explanation:

The following data were obtained from the question:

Pi (π) = 3.14

Height (h) = 21 ft

Radius (r) = 2 ft

Volume (V) =..?

The volume of the cylinder can be obtained as follow:

V = πr²h

V = 3.14 × 2² × 21

V = 3.14 × 4 × 21

V = 264 ft³

Therefore, the of the cylinder is 264 ft³

On rectangle defg, d is located at -1,-1 , F is located at 4,-8 what is length of ge

Rudiy27

Answer:

$ge= \sqrt{74}$

Step-by-step explanation:

Given

$d = (-1,-1)$

$f =(4,-8)$

Required

Length of ge

The length of ge is the same as the length of df. So, we start by calculating distance gf

$D = \sqrt{(x_1-x_2)^2+(y_1-y_2)^2}$

This gives:

$D = \sqrt{(-1-4)^2+(-1+8)^2}$

$D = \sqrt{(-5)^2+7^2}$

$D = \sqrt{74}$

This implies that:

$df = \sqrt{74}$

$ge= \sqrt{74}$
