Question

Use the graph below to answer the question that follows.

A graph titled 'Remote-Control Car' shows 'Time' in seconds from 0 to 10 on the x-axis and 'Speed' in miles per hour from 0 to 10 on the y-axis. A line segment connects (0, 4) and (3, 2). A second line segment connects (3, 2) to (8, 5). A horizontal line segment connects (8, 5) to the point (10, 5)


Which statement describes the speed of the remote-control car over time?
A. The speed of the car decreases from 4 mi/h to 2 mi/h in the first 3 seconds, increases to 5 mi/h in the next 2 seconds, and then remains at 5 mi/h for the last 5 seconds.
B. The speed of the car increases from 4 mi/h to 2 mi/h in the first 3 seconds, decreases to 5 mi/h in the next 2 seconds, and then remains at 5 mi/h for the last 5 seconds.
C. The speed of the car decreases from 4 mi/h to 2 mi/h in the first 3 seconds, increases to 6 mi/h in the next second, and then remains at 6 mi/h for the last 6 seconds.
D. The speed of the car decreases from 4 mi/h to 2 mi/h in the first 3 seconds, increases to 5 mi/h in the next 5 seconds, and then remains at 5 mi/h for the last 2 seconds.

Answer 1

i am crying because my mom is mad because I am taking so long to complete this test

Answer 2

I am sorry it is so long and hard to read, and that I don't know the answer, but please help me

Answer 3

so the speed starts at 4, decreases to 2, increases to 5 and stays there
so now just look at the graph and the choices to see which choice matches the time intervals on the graph.

Answer 4

let me look

Answer 5

What about this one:
Given the function rule f(x) = x² – 4x + 3, what is the output of f(–3)?
A. 24*********
B. 21
C. 0
D. –3

Answer 6

please come back fake mr obleck

Answer 11

we have a winner!

Answer 12

can u stay just in case i get stuck on another question

Answer 13

The data in the table illustrate a linear function.

x 0 2 4 6
y –5 –2 1 4

What is the slope of the linear function? Which graph represents the data?
B. 3/2; Four points are graphed on a coordinate plane. A line connects the four points and continues on in both directions.The points graphed on the coordinate plane are (0, -5), (2, -2), (4, 1), and (6, 4).
D. –3/2; Four points are graphed on a coordinate plane. A line connects the four points and continues on in both directions. The graph is the same as D but with a different fraction.

help please

Answer 14

ty

Answer 15

i have a lot more i need help with
😿

Answer 16

slope = (4-1) / (6-4) for example
that is
+ 3/2

Answer 17

Which hill described in the table is the steepest and why?

Street | Horizontal Distance (ft) | Vertical Rise of Street (ft)
Dixie Hill | 100 | 60
Bell Hill | 100 | 50
Liberty Hill | 100 | 20

A. Dixie Hill; it rises 5 feet for every 3 feet of horizontal travel.
B. Dixie Hill; it rises three-fifths foot for every 1 foot of horizontal travel.
C. Bell Hill; it rises 2 feet for every 1 foot of horizontal travel.
D. Liberty Hill; it rises 1 foot for every 5 feet of horizontal travel.

Answer 18

my mom is getting madder

Answer 19

ima fail now
i will be leaving to
goodbye
😿

Answer 20

calculate rise / run
60/100 = 0.60
50/100 = 0.50
20/100 = 0.20
0.60 is the most meters up for every meter horizontal
3/5 / 1 = 3/5 = 6/10 = 60/100 = 0.60 indeed so B. (A. is backwards)

Answer 21

or perhaps upside down :)
