When the light turns green, Mark accelerates straight down the road at 1.8 m/s2 for 8 seconds. What is his final velocity at the end of those 8 seconds?
Answer:
Mark's final velocity at the end of the 8 seconds is 9.6 m/s
Step-by-step explanation:
The acceleration of mark after the light turns green, a = 1.8 m/s²
The time duration of the motion with the 1.8 m/s² acceleration, t = 8 seconds
Mark's final velocity at the end of the 8 seconds, v is found using the equation of motion for velocity as follows;
v = u + a × t
Where;
u = The initial velocity = 0 m/s
a = The acceleration = 1.8 m/s²
t = The time in motion = 8 seconds
Substituting gives;
v = 0 + 1.2 × 8 = 9.6
Mark's final velocity at the end of the 8 seconds, v = 9.6 m/s.
Final velocity after 8 second is 64 m/s
Final Velocity of car:Given:
Acceleration of mark = 8 m/s²
Time taken = 8 second
Find:
Final velocity of mark
Computation:
v = u + at
v = 0 + (8)(8)
v = 64 m/s
Final velocity of mark = 64 m/s

what is the equation of a line parallel to y=3x-2 and goes through the point (-1,1)
Answer:
y = 3 x − 29
Step-by-step explanation:
First, let's find the slope of the line
y = 3 x + 2
As the equation is already in slope-intercept form
y = m x + c
Slope = 3
Let a point ( x , y ) be on the new line.
By finding the slope again,
y − 1 x − 10 = 3
y − 1 = 3 ( x − 10 )
y − 1 = 3 x − 30
Which can then be converted to different forms:
Standard form:
3 x − y = 29
Equation form:
3 x − y−29 = 0
Slope-intercept form:
y = 3 x − 29
graph{3x-y=29 [-32.3, 47.7, -34.1, 5.9]}
Find the slope of line:6x+3y=21
Answer:
-2
Step-by-step explanation:
6x+3y=21
Bring the equation to y=mx+c form
3y=21-6x
y=-2x+7
When comparing, m=-2
Slope m=-2

Convert 8 miles into kilometers. Round your answer to the nearest tenth.
8 miles is equal to 12.9 kilometers .
Given,
Convert 8 miles into kilometers .
Now,
From the metric system of unit conversion table we see that;
1 kilometer = 1000 meters (m)
1 meter = 100 centimeters (cm)
1 centimeter = 10 millimeters (mm)
Here we need the conversion factor that includes miles,
So according to the table 1 mile is equal to 1.609 kilometers .
Then,
8 miles will be equal to:
8*1.609
= 12.9 kilometers .
Hence the value of 8 miles in km is equal to 12.9 kilometers .

The legend on a map states that 1 cm is 50 km. If you measure 7 cm on the map, how many kilometers would the actual distance be?
Answer:
350 kilometers
Step-by-step explanation:
The legend states that 1 cm = 50 km
So if you do 7cm times 50
7 × 50 = 350

Compare your answers in parts B and C. Did your predictions for the coordinates of the reflected images match the actual results? Why or why
Answer/Step-by-step explanation:
Yes, it did because the coordinates of the other polygons would be a direct opposite of polygon ABCD depending on what line it reflects off of. If it reflects off of the y-axis then they would be the same coordinates, just that the X values of the coordinates would now be positive, for the reflection of the x-axis it is also the same except that now the x value would now stay negative while the y values would now be positive. For y=x, it is different because now the X, and Y place values now switch (for example, (-3,-2) would now be (-2,-3)). For y=-x, the place values would both switch, and now be positive.
PS; PLATO does not have an answer this is my personal answer since I am also on this assignment.
Sorry if this response is late! Hope you did well! :)
The coordinates of the reflected images match the actual results because of the following reason.
What is coordinate?Coordinates are two numbers (Cartesian coordinates), or sometimes a letter and a number, that locate a specific point on a grid, known as a coordinate plane. A coordinate plane has four quadrants and two axes: the x axis (horizontal) and y axis (vertical).
Yes, because the coordinates of the other polygons will be in opposite of polygon ABCD depends on what line it reflects off .
Suppose if it reflects off of on the y-axis then the coordinates will be same, only the x- coordinate will be positive.
and if the reflection of the x-axis, the coordinate will be same only the y- coordinate will be negative and the x- coordinate remain positive.
but, For y=x it is different because now the both the x- coordinate and the y- coordinate will be switched with their sign.

Representations:
Barry's profit = 5c + 20
Cheri's profit = 2c + 40
Step-by-step explanation:
well Barry's pprofit is
B = 5c + 20
and Cheri's profit is
C = 2c + 40
let's see who will get 300 first:
300 = 5c + 20
280 = 5c
56 = c
300 = 2c + 40
260 = 2c
130 = c
SO for 300 it is Barry who gets it first... same steps for others
