Y = .5(x-2) 21 I need help with this problem

Mathematics
1 answer:
Finger [1]3 years ago
7 0

Answer:

x=2

Step-by-step explanation:

Substitute y=0    0=0.5(x-2) 21

multiply the numbers     0=10.5(x-2)        *(21x0.5)

remove the parenthesis     0=10.5x-21

move the variable      -10.5x=-21

divide both sides by   -10.5

solution     x=2

The distance travelled is 10 m

The velocity gained at the end of the time is 2 m/s

<h3>Motion</h3>

From the question, we are to determine distance travelled and the velocity gained

From one of the equations of motion for <u>linear motion</u>, we have that

S = ut + 1/2at²

Where S is the distance

u is the initial velocity

t is the time taken

and a is the acceleration

First, we will calculate the acceleration

Using the formula,

F = ma

Where F is the force

m is the mass

and a is the acceleration

∴ a = F/m

Where F is the force

and a is the acceleration

From the given information,

F = 50 N

m = 250 kg

Putting the parameters into the equation,

a =  50/250

a = 0.2 m/s²

Thus,

From the information,

u = 0 m/s (Since the object was initially at rest)

t = 10 s

S = 0(t) + 1/2(0.2)(10)²

S = 10 m

Hence, the distance travelled is 10 m

For the velocity

Using the formula,

v = u + at

Where v is the velocity

v = 0 + 0.2×10

v = 2 m/s

Hence, the velocity gained at the end of the time is 2 m/s

What are the coordinates of the point on the directed line segment from (5,5) to
iogann1982 [59]

Answer:

(x,y) = (6,2)

Step-by-step explanation:

Given

(x_1,y_1) = (5,5)

(x_2,y_2) = (8,-4)

m:n  = 1:2

Required

Determine the coordinate of the partition

This is calculated using:

(x,y) = (\frac{mx_2 + nx_1}{m + n},\frac{my_2 + ny_1}{m + n})

Substitute values for m,n,x's and y's

(x,y) = (\frac{1 * 8 + 2 * 5}{1+2},\frac{1*-4 + 2*5}{1 + 2})

(x,y) = (\frac{18}{3},\frac{6}{3})

(x,y) = (6,2)

How to tell if a line is parallel perpendicular or neither?
belka [17]
Parallel is when the lines go the same direction and never touch whereas perpendicular lines are when the lines cross each other so the they are like a plus sign with all 90 degree angles. Hope i helped.
