According to the graph, what is the value of the constant in the equation

love history [14]

Answer:

The value of the constant is 3

Step-by-step explanation:

Let

y ----> the height

x ----> the width

we have

$y=kx$

This is the equation of a linear direct variation

The equation of the line passes through the origin

we have the points

(0.5,1.5), (2,6) and (3,9)

see the attached figure to better understand the problem

Find the value of the constant of proportionality k

$k=\frac{y}{x}$

For (0.5,1.5) ----> $k=\frac{1.5}{0.5}=3$

For (2,6) ----> $k=\frac{6}{2}=3$

For (3,9) ----> $k=\frac{9}{3}=3$

therefore

The value of k is equal to 3

The linear equation is

$y=3x$

$Height=3Width$

The number N of bacteria present in a culture at time t (in hours) obeys the equation N = 1000e^0.01t After how many hours will

jasenka [17]

Answer: N(t) = (2^t)*1500

Step-by-step explanation:

Let's define the hour "zero" as the initial population.

So if N(t) is the number of bacteria after t hours, then:

N(0) = 1500.

Now, we know that the population doubles every hour, so we will have that after one hour, at t = 1

N(1) = 2*1500 = 3000

after two hours, at t = 2.

N(2) = 2*(2*1500) = (2^2)*1500

After three hours, at t = 3

N(3) = 2*(2^2)*1500 = (2^3)*1500

So we already can see the pattern, the number of bacteria after t hours will be:

N(t) = (2^t)*1500

I NEED HELP ASAP!!!<br><br> Find the measure of angle A using the image below:

Andreyy89

Answer:

A = 125º

Step-by-step explanation:

Missing angle is the supplement of 157.5

180 - 157.5 = 22.5

----------------------------

Sum of angles in triangle is 180

22.5 + (-10x) + (-x + 20) = 180

Combine like terms

-11x + 42.5 = 180

Subtract 42.5 from both sides

-11x = 137.5

Divide both sides by -11

x = -12.5

---------------------------

A = -10(-12.5)

A = 125º
