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.

Which set of measurements could be the side lengths of a triangle?

Artist 52 [7]

We know that
Triangle Inequality Theorem establishes that the sum of the lengths of any two sides of a triangle is greater than the length of the third side
so
case A. 5M, 11M, 7M
5+11 > 7----> ok
11+7 > 5 ---> ok
5+7 > 11----> ok

case B.10 m, 4 m, 5 m
5+4 > 10-----> is not ok

case C.8 m, 4 m, 4 m
4+4 > 8----> is not ok

case D.6 m,11 m, 5 m
6+5 > 11-----> is not ok

the answer is
A. 5M, 11M, 7M
