What is the slope of the line described by the equation y+1=−3x

Komok [63]

Answer:

Step-by-step explanation: It is C because the slope-intercept form is y=mx+b, in which 'm' is the slope; 'b' is the y-intercept.

A cylinder has a base with a diameter of 10.8 cm and height 15 cm into the volume of a cylinder in a cubic centimeters round you

LekaFEV [45]

Answer:

$V=1,373.44\ cm^3$

Step-by-step explanation:

<u><em>The correct question is</em></u>

A cylinder has a base with a diameter of 10.8 centimeters and height 15 centimeters. Enter the volume of the cylinder, in cubic centimeters. Round your answer to the nearest hundredth

we know that

The volume of a cylinder is equal to

$V=\pi r^{2} h$

where

$r=10.8/2=5.4\ cm$ ----> the radius is half the diameter

$h=15\ cm$

assume

$\pi =3.14$

substitute

$V=(3.14)(5.4)^{2} (15)=1,373.44\ cm^3$

write the equation of the line perpendicular to y= 5/2x+3 that passes through the point (-7,9). Type an answer using slope-inter

omeli [17]

Answer:

5y = -2x + 31

Step-by-step explanation:

Given equation:

y = $\frac{5}{2} x + 3$

Coordinate = (-7,9)

Unknown:

Equation of the line perpendicular = ?

Solution:

The slope - intercept format of a line is given as;

y = mx + c

where y and x are the coordinates

m is the slope

c is the y-intercept

y = $\frac{5}{2} x + 3$

From the given equation; slope is $\frac{5}{2}$

A line perpendicular will have a slope that is negative and the inverse of this;

slope of perpendicular line = $-\frac{2}{5}$

Since y= 9 and x = -7;

So;

9 = $\frac{-2}{5} x (-7)$ + C

9 = $\frac{14}{5}$ + C

C = 9 - $\frac{14}{5}$ = $\frac{31}{5}$

Now,

y = $-\frac{2}{5}$ x + $\frac{31}{5}$

mulitply through by 5;

5y = -2x + 31

Kiran walked at a constant speed. He walked 1 mile in 15 minutes. Which of these equations represents the distance d (in miles)

galben [10]

Answer: $d=\dfrac{t}{15}$ , where d= distance that Kiran walks in t minutes.

Step-by-step explanation:

Given: Kiran walked at a constant speed.

He walked 1 mile in 15 minutes.

The, distance walked by Kiran in 1 minute = $\dfrac1{15}$ mile

The distance that Kiran walks in t minutes = $t\times\dfrac{1}{15}$ miles

If d= distance that Kiran walks in t minutes

The required equation: $d=\dfrac{t}{15}$
