Jonesville and smithville each have a population of size 2600 at time t = ​0, where t is measured in years. Suppose jonesville​'
ehidna [41]

Answer: B. Jonesville is growing linearly and Smithville is growing exponentially.

Step-by-step explanation:

Linear growth :

  • Population grow by a constant amount after each time period.
  • The rate of change of dependent variable with respect to independent variable is a constant.
  • It is represented by line on graph.
  • Equation for linear growth : y=mx+c , c = initial value and m is the rate of change of y with respect to x.

Exponential growth :

  • Population grow by a constant ratio .
  • It is represented by a curve on graph.
  • Equation for exponential growth : y=a(1+r)^x , a = initial value and r is  rate of growth ( in decimal ) and x is time period.

Given : Jonesville​'s population grows by 170 people per year.

i.e .Population grow by a constant amount per year.

⇒ Jonesville is growing linearly.

The population of smithville grows by 7​% per year.

i.e. Population grow by a constant ratio.

⇒Smithville is growing exponentially.

Hence, the true statement is "B. Jonesville is growing linearly and Smithville is growing exponentially."

Schach [20]

<u>Answer:</u>

<h2>x ≈ 4.5</h2>

<u>Steps:</u>

tan(37°) = 0.75..

tan(37°) = x/6

x/6 = 0.75..

x = 0.75.. × 6

x = 4.52.. ≈ 4.5

the ratio of reds to greens was 5 to 16 and six times the number of reds exceeded the number of greens by 112. how many were red
Masja [62]
Call red as X then X/Green =5/16 => green = 16X/5.
six times the number of reds exceeded the number of green by 112 => 6X-16X/5=112 => 14X/5=112 => X= 40 => reds:40 => green = 128
