NEED SOME HELP WITH THIS EXERCISES, PLEASE!! 1. Henry has been measuring the length of his baby`s nail. The first time it was 2cm long and

after one month it was 2.2 cm long. If the nail continues to grow at this rate:

a. Determine the linear function that represents the nail growth

b. What is the baby`s nail length after 6 months?

2. Daniel is driving a remote control car at a constant speed. He starts the timer when the car

is 9 feet away. After 6 seconds the car is 54 feet away.

a. Write a linear equation to find the distance D of the car from Daniel

b. Estimate the distance the car has traveled after 45 seconds

3. In 1995, Orlando, Florida, was about 175,000. At that time, the population was growing at

a rate of about 2000 per year. Write an equation, in slope-intercept form to find Orlando’s

population for any year. Predict what Orlando’s population will be in 2010

step-by-step explanation:

bob the banana

ratio is 2 : 9

the answer is three

13.5 : 3

the value of x is 9 ⇒ answer b

step-by-step explanation:

* we can solve this problem using cosine and sine rule

- in δ abc

∵ ab = 36 , bc = 28 , ac = 16

- lets find the measure of angle b using the cosine rule

∵ cos b = [ab² + bc² - ac²]/2(ab)(bc)

∴ cos b = [36² + 28² - 16²]/2(36)(28)

∴ cos b = 19/21

∴ m∠b = cos^-1(19/21) ≅ 25°

- lets find the measure of angle a using the sine rule

∵ sina/bc = sinb/ac = sinc/ab

∴ sina/28 = sin25°/16 ⇒ by using cross multiplication

∴ sina = 28 × sin25°/16

∴ sina = 0.7396

∴ m∠a = sin^-1(0.7396) ≅ 48°

- from the figure m∠abd = m∠dbc

∵ m∠abc = 25°

∴ m∠abd = 25°/2 = 12.5°

- in δabd

∵ m∠a = 48° , m∠abd = 12.5°

∵ the sum of the measures of the interior angles of any δ is 180°

∴ m∠adb = 180° - (48° + 12.5°) = 119.5°

∵ ab = 36

∵ ad = x

- use the sine rule to find x

∵ sin∠adb/ab = sin∠abd/x

∴ sin119.5°/36 = sin12.5°/x ⇒ by using cross multiplication

∴ x = 36 × sin12.5°/sin119.5° = 8.95 ≅ 9

* the value of x is 9

8(4)^8=72^feet to say that the total can conclude to 8(4) which as you know would mean 8 x 4. that equals 32w. 32^ could make a 72 answer as well. but your coefficent will remain w so your answer is 72w.
