I need help please!
Vlad1618 [11]

Answer:

\Huge \boxed{y=3x+6}

Step-by-step explanation:

y = mx + b

m = slope

b = y-intercept

The slope can be found from two points.

\displaystyle m=\frac{y_2-y_1}{x_2-x_1}

The two points from the graph are (1, 9) and (2, 12).

Plugging in the values and evaluating.

\displaystyle m=\frac{12-9}{2-1}

\displaystyle m=\frac{3}{1}

m=3

The slope of the line is 3.

The y-intercept of the line is where the line cross the y-axis.

The line crosses the y-axis at (0, 6).

b=6

The slope-intercept form of the line is:

y=3x+6

A robotic machine fills containers with an acid solution at the rate of 50 + 5 t milliliters (mL) per second, where t is in seco
Alika [10]

Answer:

12,000

Step-by-step explanation:

The machine fills the containers at a rate of 50+5t milliliters (mL) per second.

Therefore, the rate of change of the number of containers, N is:

\dfrac{dN}{dt}=50+5t, 0\leq t\leq 60

dN=(50+5t)dt\\$Taking integrals of both sides\\\int dN=\int (50+5t)dt\\N(t)=50t+\frac{5t^2}{2}+C $(C a constant of integration)\\\\When t=0, , No containers are filled, therefore:$ N(t)=0\\0=50(0)+\frac{5(0)^2}{2}+C\\C=0\\$Therefore, N(t)=50t+2.5t^2

When t=60 seconds

N(60)=50(60)+2.5(60)^2\\N(60)=12000$ mL

Therefore, 12,000 milliliters of acid solution are put into a container in 60 seconds.
