An object is dropped off a cliff and falls freely. It speeds up as it falls toward the ground.
The graph below shows the velocity in meters per second (m/s) of the object (denoted by the vertical axis) as a function of time in seconds (denoted by the horizontal axis). Note that the relationship is linear.
This relationship is given by the equation, v = gt. In this equation, g is the acceleration due to gravity, t is the number of seconds, and v is the velocity of the falling object. Note that g is a constant.
Find and interpret the meaning of the initial value and the rate of change in this context.
Answer:
The initial value is 0. That means that object’s initial velocity 0 m/s. The rate of change is 9.8. That means the acceleration due to gravity is 9.8 m/s 2.

Ritus mother's age is 7 years more than two time Ritus age. Ritus mother is 37 years old. Set up an equation to find Ritus age (Take Ritus age to be 'x' years)
Answer:
2x + 7 = 37
Ritu's age = 15 years
Step-by-step explanation:
Given:
Ritu's mother age = 37
Find:
Ritu's age
Assume;
Ritu's age = x
So,
2x + 7 = 37
2x = 30
x = 15
Ritu's age = 15 years
What is the answer please need help
Answer:
130
Step-by-step explanation:
so you take 35+95=130
then you take 180-130=50 to get the other angle in the triangle
then to get the missing angle you do 180-50=130
so that is the missing angle

3. Emma purchased a bicycle at a garage sale for $56. She later sold the bicycle online for $85.What was the percent increase of the price of the bicycle?
Answer:
51.7857143% increase is the percent increase of the price of the bicycle.
Step-by-step Explanation on finding percent increase using this question:
Formula needed:
% increase = 100 x (final-initial)/ | initial |
1. % increase = 100 x (85-56)/56
2.% increase = 100 x 29/56
3. % increase = 100 x 0.517857143
4. % increase = 51.17857143 (final answer)
Round if told by directions to do so.

standardized testing. She calls randomly-chosen parents between 4:00 and 5:00 P.M.
every day for a week and collects data on their responses. Identify the population
and the sample. Give a reason why the sample could be biased.
Oa)
Population: All parents who respond to the survey
Sample: All parents with students at the school
Possible Bias: The parents who answered the phone may not be
representative of the whole population because younger parents are more
likely to answer the phone than older ones.

Population: All parents with students at the school
Sample: All parents who respond to the survey
Possible Bias: Parents who are at home between 4:00 and 5:00 P.M. may not
be representative of the whole population.
Oc) Population: All parents with students at the school

Answer:
$66
Step-by-step explanation:
→ Work out 45% as a multiplier
100 - 45 = 55 ⇒ 55 ÷ 100 = 0.55
→ Multiply the multiplier by the price
0.55 × 120 = $66
Answer:
54
Step-by-step explanation:
120 times 45 equals 5400 divided by 100 equals $54

The price of Stock A 9 AM was $12.71. Since then, the price has been increasing at the rate of $0.05 each hourAt noon the price of Stock 8 was \$13.46 . To decrease at the rate of by $0.12each hour. If the two rates continue, in how many hours will the prices of the two stocks be the same?
Answer:
4.4 hours
Step-by-step explanation:
Let the number of hours be represented as h
The price of Stock A 9 AM was $12.71. Since then, the price has been increasing at the rate of $0.05 each hour
$12.71 + $0.05 × h
12.71 + 0.05h
At noon the price of Stock 8 was \$13.46 . To decrease at the rate of by $0.12each hour.
$13.46 + $0.12 × h
13.46 - 0.12h
If the two rates continue, in how many hours will the prices of the two stocks be the same?
12.71 + 0.05h = 13.46 - 0.12h
0.05h + 0.12h = 13.46 - 12.71
0.17h = 0.75
h = 0.75/0.17
h = 4.41176470588 hours
Approximately = 4.4 hours
The prices of the two stocks be the same in 4.4 hours
Carlita saw 5 times as many robins as she did cardinals while bird watching. She saw a total of 36 birds. How many more robins did she see than cardinals?
Answer: Calita saw 30 Robins and 6 Cardinals
Step-by-step explanation:
Step 1
writing the mathemathecal expression becomes
Let robins be represented as R
and Cardinals be represented as C
so our first equation becomes
R+C = 36----- eqn 1
but she saw 5times as many robins as cardinals, with a total of 36 birds making us have
Therefore R= 5C
5C +C= 36------- eqn 2
STEP 2--- solving equation 2
5C+C = 36
6C= 36
C= 36/6=6
Puting the valueof C=6 in equation 1 becomes
R+C= 36
R+6=36
R=36-6= 30
R=30
Therefore Calita saw 30 Robins and 6 Cardinals
Which values of x are solutions to this equation? |x/-4| = 2
-x = 4 or x = 8
-x = 2 or x = 6
-x = -2 or x = 2
-x = -8 or x = 8
Answer:
Step-by-step explanation:
|x/-4| = 2 corresponds to two different equations:
1) -x/4 = 2 if x/-4 is already positive, and
2) x/4 = 2 if -x/4 is negative, due to the absolute value operator
In case 1, -x = 8, or x = -8
and
in case 2, x = 8
so the solution set is {-8, 8}
Double check to ensure that you have copied down this problem correctly. Your " |x/-4| " looks odd/ambiguous

Consider each graph shown. Determine the slope of each line
and then use similar triangles to justify that the slope is the
same between any two points.
Answer:
18,1,18
Step-by-step explanation:
The slope of a line from the given graph is 4 units.
From the given graph, vertical line (rise) = 16 and horizontal line (run) = 4.
What is slope of a line?The slope of the line is the ratio of the rise to the run, or rise divided by the run. It describes the steepness of line in the coordinate plane.
Now, slope = Rise/Run
⇒ slope = 16/4
= 4 units
Therefore, the slope of a line from the given graph is 4 units.
