Answer:

Option B. No, because the graph of the line connecting the ordered pairs does no pass through the origin.

Step-by-step explanation:

we know that

A relationship between two variables, x, and y, represent a proportional variation if it can be expressed in the form $k=\frac{y}{x}$ or $y=kx$

In a proportional relationship the constant of proportionality k is equal to the slope m of the line<u><em> and the line passes through the origin</em></u>

step 1

Connect the ordered pairs of the graph

The y-intercept is the point (0,20)

see the attached figure

That means, that the line not passes through the origin

therefore

The relationship between the two quantities is not proportional

you invest $4,100 in an account that pays an interest rate of 8.5%, compound continuously. Calculate the balance of your account

Yanka [14]

Answer:

16400$

Step-by-step explanation:

Persent invest value= 4100$

Compound intrest rate=8.5% or 0. 085 (annual)

Time period =17 years

According to compound interest formula

Future valve (fv) =persent value(pv) (1+r)^n

Substitute all values

Fv=4100$(1+0.085)^17

Fv=4100$(1.085)^17

Fv=4100 * 4.00

Fv= 16400 $ answer

In 1995, the moose population in a park was measured to be 1800. By 1998, the population was measured again to be 2400. If the p

Shalnov [3]

The linear equation for the variation of population is p = 200t + 1800.

<h3>What is an equation?</h3>

An equation is defined as the relation between two variables, if we plot the graph of the linear equation we will get a straight line.

The formula for an equation in intercept form will be given as below:-

y = mx + c.

It is given that In 1995, the moose population in a park was measured to be 1800. By 1998, the population was measured again to be 2400.

Write the linear equation for population variation.

p = mt + c

m = Rate of change = ( 2400 - 1800 ) / 3 = 200, put the value in the equation.

p = 200t + c

Put the values in the equation to get the value of the constant.

2400 = 200 x 3 + c

c = 2400 - 600

c =1800

The equation for the linear variation of the population is,

p = 200t + 1800

Therefore, the linear equation for the variation of the population is p = 200t + 1800.
