Slope is 3/7,and (4,9) is on the line
TiliK225 [7]

Answer:

y-9=\frac{3}{7}(x-4)

or

y=\frac{3}{7}x+\frac{51}{7}

Step-by-step explanation:

To write the equation of the line using a slope and a point, use the point-slope formula y-y_1 = m(x-x_1). Here m is 3/7. And the point (x_1,y_1) is (4,9). Substitute the values and simplify.

y-y_1=m(x-x_1)\\y-9=\frac{3}{7}(x-4)\\y-9=\frac{3}{7}x - \frac{12}{7}\\y=\frac{3}{7}x -\frac{12}{7} + 9\\y=\frac{3}{7}x + \frac{51}{7}

Both the point slope form and the final simplified form are considered equations of the line.

Answer:

graphic attached

Step-by-step explanation:

Hi

when t = 0 then s (t) = 1/4

when t tends to infinity then s (t) tends to 0

when t tends to infinity then s (t) tends to infinity

In January, the depth of a lake was 1,014 feet. In August, the depth of the lake was 659.1 feet. What is the percentage decrease
Colt1911 [192]

Answer:

35% decrease

Step-by-step explanation:

To find the percent decrease, divide the difference in price by the original price:

(1014 - 659.1) / 1014

354.9 / 1014

= 0.35

So, the percent decrease was 35%

A city block has 6 pigeons and then 1 week later there are 9 pigeons. Let P(t)be the number of pigeons where t is measured in we
Pavel [41]

Using proportions, it is found that the differential equation which describes the growth of the pigeon population is given by:

\frac{dP}{dt} = 1.5P

<h3>What is a proportion?</h3>

A proportion is a fraction of a total amount, and the measures are related using a rule of three.

In this problem, considering the initial population and the population one week later, the rate of growth is given by:

k = 9/6 = 1.5.

The standard differential equation for population growth is:

\frac{dP}{dt} = kP

Hence:

\frac{dP}{dt} = 1.5P
