Time is C. 50 seconds

Step-by-step explanation:

The population of bacteria at time t here is given by

0.2b=\frac{t^2}{20}

where

b is the number of bacteria

t is the time in seconds

Here we want to find the approximate time at which the number of bacteria is

b = 625

Substituting into the equation and solving for t, we find:

t^2=20\cdot 0.2 b\\t=\sqrt{4b}=\sqrt{4\cdot 625}=50 s

Therefore, the solution is

C. 50 seconds

kupik [55]

Answer:

As we know rectangles have 90 degree angles at all 4 of its corners.

In this question we know that the length is 4 feet while the bredth is 3 feet.

Therefore to solve this answer we can use the Pythagoras theorm.

By Pythagoras:

4^{2} + 3^{2} = diagonal^{2}

Therefore the diagonal must be 5 feet

So if Luisa measures the diagonal with a tape and it measures 5

Then it proves that all 4 corners due have 90 degree angles

Please do mark my answer as brainliest. It would really help me answer more of such questions in the future :)

20 POINTS ASAP The graphed line can be expressed by which equation? Math item stem image y+3=32(x+1) y−0=−32(x+1) y−3=32(x−1) y−
storchak [24]

Answer:

The Answer is: y - 3 = 3/2(x - 1)

Step-by-step explanation:

Given Points: (1, 3) and (-3, -3)

Find the slope m:

m = y - y1 / (x - x1)

m = 3 - (-3) / (1 - (-3))

m = 3 + 3 / 1 + 3

m = 6 / 4 = 3/2

Use the point slope form and point (1, 3):

y - y1 = m(x - x1)

y - 3 = 3/2(x - 1)

Hope this helps!  Have an Awesome day!! :-)
