*USE THE FIRST PICTURE TO ANSWER ALL THE QUESTIONS*

*THE SECOND PICTURE IS THE 4TH QUESTION*

1.) Assume the segment AB has already been constructed. What is the first step to construct the segment XY?

A. Draw a ray and label the endpoint X or Y.

B. Plot two points X and Y (one an endpoint) and draw a ray through them.

C. Plot two points A and B (one an endpoint) and draw a ray through them.

D. Draw a ray and label the endpoint A or B.

2.) What is the second step in the construction?

A. Place the compass at point A (or B) and draw an arc through B (or A).

B. Open the compass to the length of XY.

C. Place the compass at point X (or Y) and draw an arc through Y (or X).

D. Open the compass to the length of AB.

3.) What is the final step of the construction?

A. With the same compass setting, put the compass point on the endpoint of the construction in the first step and draw an arc that intersects the ray. Label the intersection A or B depending on the name of the other endpoint.

B. Draw the segment starting from point X (or Y) through the arc created in the previous step. Label the intersection Y (or X).

C. Draw the segment starting from point A (or B) through the arc created in the previous step. Label the intersection B (or A).

D. With the same compass setting, put the compass point on the endpoint of the construction in the first step and draw an arc that intersects the ray. Label the intersection X or Y depending on the name of the other endpoint.

the answer

b. they are parallel and will never intersect.

part a

answer: a reasonable domain is where n is a real number. so n can be between 0 and 10. both endpoints are included.

work shown:

n is the number of days after the experiment starts. the smallest n can be is n = 0 which means that 0 days have gone by, and we're at the start. to find out how large n should be, then replace f(n) with 16.13 and solve for n. use logarithms to isolate the exponent.

f(n) = 12*(1.03)^n

16.13 = 12*(1.03)^n

16.13/12 = (1.03)^n

1.34416666666667 = (1.03)^n

(1.03)^n = 1.34416666666667

log[ (1.03)^n ] = log[ 1.34416666666667 ]

n*log[ 1.03 ] = log[ 1.34416666666667 ]

n = log[ 1.34416666666667 ]/log[ 1.03 ]

n = 10.0062999823929

this rounds to n = 10 which is fairly close but not 100% perfect. so this is the largest n can be.

note: if you plug n = 10 into f(n), you'll get roughly 16.127 which rounds to 16.13 (this comes up again in part c)

=====================================

part b

answer: the y intercept is 12. it represents the starting height of the plant in cm.

work shown:

plug n = 0 into the f(n) function. simplify

f(n) = 12*(1.03)^n

f(0) = 12*(1.03)^0

f(0) = 12*(1)

f(0) = 12

on day n = 0, aka the starting point, the height f(n) is 12 cm

=====================================

part c

answer: the average rate of change is approximately 0.43061036458991 (round however you need to). this represents the average growth rate from day n = 3 to day n = 10. so the plant grew roughly 0.43 cm per day during this timespan, assuming you round to 2 decimal places.

work shown:

compute f(3)

f(n) = 12*(1.03)^n

f(3) = 12*(1.03)^3

f(3) = 13.112724 < we'll use this later

compute f(10)

f(n) = 12*(1.03)^n

f(10) = 12*(1.03)^10

f(10) = 16.1269965521294 < we'll use this later

now use the formula below with a = 3 and b = 10

aroc = average rate of change

aroc = [ f(b) - f(a) ]/[ b - a ]

aroc = [ f(10) - f(3) ]/[ 10 - 3 ]

aroc = (16.1269965521294 - 13.112724)/(10 - 3)

aroc = 3.0142725521294/7

aroc = 0.43061036458991

round this however you need to

note: the plant grew approximately 3.01 cm over 7 days, so roughly 0.43 cm per day is the average growth rate (if you were to round to 2 decimal places).
