Simplify each expression as much as possible, and rationalize denominators when applicable. √72=?
Misha Larkins [42]

Answer:

6√2

Step-by-step explanation:

Solving the given expression step by step:

72 = 2 × 2 × 2 × 3 × 3

Now for finding the square root we will make pair of two numbers of same values.

We have one pair of 2's and one pair of 3's and left one 2

Thus, √72 = 2 × 3 × √2 = 6√2

We rationalize denominator and change it into a simpler form as soon as possible.

Identify the slope and y-intercept of the function y= -5x+4
Rufina [12.5K]

Answer:

The slope is -5 and the y intercept is (0,4). (D).

Step-by-step explanation:

The formula for this is y=mx+b. With m equaling the slope, and b equaling the y intercept. In the place of m, there is -5, getting you your slope of -5 and in the place of b there is 4 (meaning the coordinate (0,4)), getting you your answer. I hope this helps! :)

A population of protozoa develops with a constant relative growth rate of 0.6137 per member per day. On day zero the population
Wewaii [24]

Answer:

The population size after seven days will be 171.

Step-by-step explanation:

The population of protozoa can be modeled by the following equation.

Q(t) = Q(0)(1+r)^{t}

In which Q(t) is the population after t days, Q(0) is the initial population and r is the growth rate.

In this problem, we have that:

Q(0) = 6, r = 0.6137

So

Q(t) = 6(1.6137)^{t}

Find the population size after seven days.

This is Q(7).

Q(7) = 6(1.6137)^{7} = 171

The population size after seven days will be 171.
