Since $x=10$ we know our function is $f(x)=x^{2}+3$ .

To solve, substitute the given value:
$f(10)=10^{2}+3=100+3=103$

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."

0.8y+0.25= -0.4<br><br> Solve for y

disa [49]

Answer:

y = -13/16

Step-by-step explanation:

<u>Given:</u>

0.8y+0.25= -0.4

<u>To Find:</u>

Solve for y

<u>Solution:</u>

Multiply both sides by 100

$0.8y\cdot \:100+0.25\cdot \:100=-0.4\cdot \:100$

Simplify

$80y+25=-40$

Subtract 25 from both sides

$80y+25-25=-40-25$

Simplify

$80y=-65$

Divide both sides by 80

$\frac{80y}{80}=\frac{-65}{80}$

Simplify

$y=-\frac{13}{16}$

Thus, y = -13/16

or in decimal form it equal y = -0.8125
