You were 20 inches tall at birth, and 65 inches tall on your 10th birthday. Create a linear equation to
represent this situation. According to your equation, how tall will you be at age 20?
Answers
height at 20: 90in
Explanation-
linear equation:
x represents the number of years
y represents the height in inches
we’ll have the points
(0,20) height at birth
(8, 48) height at 8th birthday
to find slope you would do
m= (48-20)/(8-0)
= 3.5 inches/year
b would be 20
so y= mx + b would give you
y=3.5x + 20
if you add 20 into that equation you’d get
y= 3.5(20) + 20 = 90inch
y=90

you start at (2, 4). You move down 4 units and up 4 units. Where do you end?
Answers
Answer:
(2, 4)
Step-by-step explanation:
the same spot because 2 - 4 = -2, and the back up -2 + 4 = 2. we do not move left or right so there is no need to change the y value of 4
Answer:
(2, 4)
Step-by-step explanation:
We are given the points (2, 4) and we are told to move down four units, and then up 4 units. Since it's up and down not left and right it's telling us that we are moving the point on the y axis, which is the four, now all we have to do is subtract four units, and then add four more units on the y axis.
4 - 4 + 4 = 4
Leaving the points unchanged, your answer is "(2, 4)."
Hope this helps.

Mary works at the Elementary School, but has to go to the airport to pick up her father. Her father works at City Hall. She drops her father at City Hall and then returns to the Elementary School. How far did Mary travel if she took the shortest route?
A. 32 miles
B. 36 miles
C. 64 miles
D. 96 miles
Answers
Answer:
D. 96 miles
Step-by-step explanation:
So, first, to get to the airport, we can take the shortest route, which is Elementary School to City Hall (21), then to High School (12), then to Airport (15).
This adds up to 48 miles.
Then, we go back to City Hall, through the High School, which is 27 miles (15+12)
Then, we go to the Elementary School from City Hall, which is 21 miles.
Add up all the miles and you get:
48 + 27 +21 = 96

Hi there !
A = Asemicircle + Atrapeze
Asemicercle formular = d/2 = 20mm/2 = 10mm
Asc = π·r²/2
= 3.14·(10mm)²/2
= 3.14×100mm²/2
= 157 mm²
Atrapeze formulaAt = (b + B)×h/2
= (20mm + 32mm)×14mm/2
= 52mm×7mm
= 364 mm²
A = Asc + At= 157mm² + 364mm²
= 521 mm²

State the range of f(x) on this domain interval.
Answers
Answer:
The range of a function is the set of outputs of the function
on the graph, outputs of a function are on the y-axis. So we will see the highest and the lowest output of this function
From the graph, we see that the function has the outputs:
{0 , 1 , 2 , 3 , 4 , 5 , 6}
Therefore, this is the range of the function

b. In an experiment, people must give their informed consent before being allowed to participate.
c. Observational studies are always biased.
d. Observational studies cannot have response variables.
e. An experiment imposes treatments on the subjects, but an observational study does not.
Answers
Answer: e. An experiment imposes treatments on the subjects, but an observational study does not.
Step-by-step explanation:
Experiment is scientific procedure that is undertaken by an individual or a researcher in order for the person to either make a discovery, or test a hypothesis.
Observational studies are the studies whereby the researchers just observe the impact of a treatment or risk factor e.g. cohort studies. In observational study, the researchers just collect data based on what they've either heard or seen and they've no control over such variables collected whole for an experiment, treatments are applied to a group and the effects are recorded.

Use vector operations to draw the resultant vector
Draw 2u – 1/3v.
Answers
Vectors are elements of the vector space, and they can be illustrated by diagrams.
How to draw the vector 2u - 1/3vThe vector expression is given as:
2u - 1/3 v
Split the vector expressions, as follows:
[tex]y_1 = 2u[/tex]
[tex]y_2 = -\frac13v[/tex]
See attachment for the graphs of y1 and y2.
Next, we have:
[tex]y = 2u - \frac13v[/tex]
So, we have:
[tex]y = y_1 + y_2[/tex]
The above expression means that, we add the vectors y1 and y2 to get vector y

Step-by-step explanation:
total cost = monthly cost plus the cost of lessons
total cost = $325
monthly cost = $45
