Answer:

SR is a secant of circle P

Step-by-step explanation:

see attachment for the missing figure.

In the circle P,

Option A:

N is a point of tangency on circle P.

As Q is a point of tangency of circle P. Therefore, the statement is not true.

Option B:

PT is a secant of circle P.

As PT is a radius of the circle P. Therefore, the statement is not truee.

Option C:

SR is a secant of circle P.

It is true by the above bulleted points.

Option D:

VU is a tangent of circle P.

As VU is a diameter of the circle P. Therefore, the statement is not true

Therefore, the true statement is SR is a secant of circle P

dusya [7]

Answer:

2/11

Step-by-step explanation:

6 = 2 x 3

6/11 x 1/3

= ( 6 x 1 )/( 11 x 3 )

= ( 2 x 3 x 1 )/( 11 x 3 )

Cancel 3 in both numerator and denominator.

= ( 2 x 1 )/( 11 )

= 2/11

The table shows the results of a survey on people’s favorite fruit. What percent of the people chose strawberry as their favorit

Sphinxa [80]

Answer:

24.2%

Explanation:

The percentage of people choosing strawberry can be calculated as follows:

$Percentage = \frac{PeopleChoosingStrawberry}{TotalNumberOfSurveyedPeople} * 100$

We have:

Number of people choosing strawberry = 15 people

Total number of surveyed people = 17 + 10 + 17 + 3 + 15 = 62 people

Substitute in the above rule to get the percentage as follows:

$Percentage = \frac{15}{62}*100 = 24.19 = 24.2$ %

Hope this helps :)

The initial cost to drill a well is $210000. the daily rate to operate the well is $500. The current selling price is $65 per ba

SVETLANKA909090 [29]

Hi there!

There is an initial cost of $210,000 (which you're just going to pay once)

Then it costs $500 per day to operate.

The number of days is represented by "x".

Your equation in function notation should look like this :

f(x) = 500x + 210,000

There you go! I really hope this helped, if there's anything just let me know! :)

A substance with a half life is decaying exponentially. If there are initially 12grams of the substance and after 70 minutes the

dybincka [34]

Answer:

Step-by-step explanation:

Use the half life formula

$N=N_0e^{kt}$ where N is the amount after decay, No is the initial amount, e is Euler's number, k is the decay constant, and t is the time in minutes. For us, the first equation looks like this:

$7=12e^{k(70)}$ and we will solve that for k and then use that value of k in the second equation to find time.

Begin by dividing 7 by 12 to get

$\frac{7}{12}=e^{k(70)}$ Now take the natural log of both sides since the natural log and that e are inverses. The e then disappears:

$ln(\frac{7}{12})=k(70)$

Plug the left side into your calculator and then set it equal to the right side, giving us:

$-.5389965007=70k$

Divide both sides by 70 to get the k value of

k = -.00769995

Now the second equation looks like this:

$2=12e^{(-.00769995)t$ where t is our only unknown now that we know k.

Begin by dividing both sides by 12 to get

$\frac{1}{6}=e^{-.00769995t$ and take the natural log of both sides again to eliminate the e:

$ln(\frac{1}{6})=-.00769995t$

Take care of the left side on your calculator to get

-1.791759469 = -.00769995t and divide both sides by -.00769995 to get

t = 232.697 minutes
