A line tangent to a circle and a radius of the same circle intersect at the point of tangency to create an angle of what measure

1 answer:

3 0

A theorem states that, given a circle with center C and a point P on the circumference, the tangent line through P and the radius CP are perpendicular.

So, the answer is 90 degrees.

A population of a particular yeast cell develops with a constant relative growth rate of 0.4225 per hour. The initial population

Ksju [112]

Answer: The population after 3 hours is 13.9 mill.

Step-by-step explanation:

When we have an exponential with:

A = initial population.

r = constant relative growth rate:

t = time.

The function that models this is:

P(t) = A*e^(k*t)

In this case we know that:

A = 3.9 mill.

r = 0.4225 1.

Then the function that models the population of this yeast cell is:

P(t) = (3.9 mill)*e^(0.4225*t)

where t represents the time in hours.

Then if we want to know the population after 3 hours, we should replace t by 3.

P(3) = (3.9 mill)*e^(0.4225*3) = 13.85 mill.

And we want to round our answer to one decimal place, then we must look at the second decimal place, we can see that is a 5, so we should round up.

The population after 3 hours is 13.9 mill.

Arte-miy333 [17]

Answer: 1,259 meters.

Step-by-step explanation:

GIven: The highest elevation in a small country occurs on a mountain above sea level = 1,232 meter

The lowest elevation in the same country occurs below sea level = -27 meters

The difference in elevation between the highest and lowest points = Highest - lowest

= 1232 - (-27) meters

= 1232+27 meters [ (-)(-)=(+) ]

= 1259 meters

Hence, the difference in elevation between the highest and lowest points = 1,259 meters.

A one-year membership to a gym costs $725. The registration fee is $125, and the remaining amount is paid monthly. Define a vari

wel

Given :

A one-year membership to a gym costs $725.

The registration fee is $125.

To Find :

How much new members pay each month.

Solution :

Remaining fee = Total fee - Registration fee

R = $( 725 - 125 )

R = $600

Amount of fee paid monthly is :

$C=\dfrac{R}{12}\\\\C = \dfrac{600}{12}\\\\C = \$50$

Therefore, monthly fee is $50.

Hence, this is the required solution.
