A Child’s Growth and Prosperity
When a new baby enters this world, pediatricians will monitor the baby’s growth in many areas. Weight, head circumference, length, and body mass index are just a few of the measurements collected as newborns progress through childhood. Parents of newborns are not only concerned with their child’s measurements, but they typically consider their child’s medical and financial needs, too.
As you complete the task, keep these questions in mind: How can you use linear functions to describe and analyze measurements associated with babies’ growth? How can you use functions to calculate college savings and to determine how much medicine to administer?
Directions:
Complete each of the following tasks, reading the directions carefully as you go.
You will be graded on the work you show, or your solution process, in addition to your answers. Make sure to show all of your work and to answer each question as you complete the task. Type all of your work into this document so you can submit it to your teacher for a grade. You will be given partial credit based on the work you show and the completeness and accuracy of your explanations.
Answer:
a) 0.75 inch/month
b) y-20 = 0.75(x-4)
c) 17 inches
d) 44
a) 0.8 inch/month
b) yes
c) y = 0.8x + 18.8
d) 18.8 inches
Step-by-step explanation:
a) (21.5-20)/(6-4) = 1.5/2
= 0.75 inch/month
If this is correct, 2 months after the 6th month (month 8), it should be
21.5 + 2(0.75) = 23
Which it is
b) y-y1 = m(x-x1)
Where y is the length, x is the months, m is the slope and (x1,y1) is a known point
At x = 4, y = 20
y-20 = 0.75(x-4)
Or
y = 0.75x + c
20 = 0.75(4) + c
c = 20 - 3 = 17
y = 0.75x + 17
c) at birth, 4 months before month 4
So, 20 - 0.75(4) = 17
Which is also the y-intercept
d) y = 0.75(36) + 17
y = 27 + 4 = 44 inches
Generally, at the age of 3 years (36 month) the length is between 35 and 40 inches
a) slope = (30-22)/(14-4)
= 0.8 inch/month
b) 0.8 > 0.75, so yes
c) When x = 4, y = 22
y-22 = 0.8(x - 4)
y - 22 = 0.8x - 3.2
y = 0.8x + 18.8
y-intercept is 18.8
d) at birth, x = 0.
Length was 18.8 inches

15 tan^3x=5tanx,(0,2pi)
Answer:
steps below
Step-by-step explanation:
15 tan³x=5tanx .... (0,2π)
5tanx(3tan²x - 1) = 0
tanx = 0 x = π (0° is excluded)
or 3tan²x - 1 = 0
(√3 tanx + 1) (√3 tanx - 1) = 0
tanx = 1 /√3 x = π/6 (30°) or x = 5π/6 (150°)
tanx = - 1 /√3 x = 7π/6 (210°) or x = 11π/6 (330°)

Find the equation for the line shown
Answer:
2y-x=0
Step-by-step explanation:
Slope(m)= (5-2)/(10-4)=3/6=1/2
y-intercept(c)=0
y=mx+c
y=1/2*x+0
y=x/2
2y-x=0

Answer:
30,012.5
Step-by-step explanation:
We power the number by itself for the past years so in this it will be 3.5 powered by itself four times equaling 150.0625 multiplied by the first deposit which is 200 so 200*150.0625= 30,012.5

Answer:
[tex]x = \sqrt{6} [/tex]
Step-by-step explanation:
2(x^2 - 6) = - 3x^2 + 18
2x^2 - 12 = - 3x^2 + 18
5x^2 - 12 = 18
5x^2 = 30
x^2 = 6
x = square root (6)

Step-by-step explanation:
THE ANSWER IS 78
Finally, suppose you decide not to finance (get a loan for) the car and to
wait two years to save up money in addition to the $4,000 you already
have saved for the car.
How much money would you have to save each month in order to
purchase this car without any financing (loan) at the end of two years?
Round your answer to the nearest cent.
Supposing a cost of $30,000, and using proportions, it is found that you would have to save $1,083.30 each month.
--------------------------
We suppose a cost of $30,000.You already have $4,000 saved.30 - 4 = 26, thus, you would need to save $26,000 in 2 years = 24 months.How much per month?We can solve it using proportions, by the following rule of three:
1 month - $x
24 months - $26,000
Applying cross multiplication:
[tex]24x = 26000[/tex]
[tex]x = \frac{26000}{24}[/tex]
[tex]x = 1083.3[/tex]
You would have to save $1,083.30 each month.
