Mathematics

Effectus [21]3 years ago

Answer: A circle is 360° all the way around; therefore, if you divide an arc's degree measure by 360°, you find the fraction of the circle's circumference that the arc makes up. Then, if you multiply the length all the way around the circle (the circle's circumference) by that fraction, you get the length along the arc.

love history [14]

Answer:

760772

Step-by-step explanation:

Given that the  population of city Z was 420,000 in the year 2000.

The population is projected to grow at a constant rate of 2 percent per year,

We have to find the  closest to the projected population of city Z in the year 2030

Since growing at 2% per year treating 2000 as year 0 we can say

P(t)= 420000(1+0.02)^t where t is the no of years lapsed after 2000.

So at the year 2030, t = 30

Population at th eyear 2030

= P(30) = 420000(1.02)^{30} \\=760771.86\\=760772

the projected population of city Z in the year 2030 is 760772

This is #16. Now #17 says “For question #16, find a value of x that makes lines u and v intersect.” Help me.
pashok25 [27]
When you solved for x in #16, you were looking for the value of x to see what x would make both angles congruent since they were alternate interior angles. The same solution x=8, is the solution to #17 when the two lines will intersect.
If you graph both lines they will intersect at x=8.

AnnZ [28]

Answer :

<h3>4^{10} <u> =1048576 ways </u> a student can answer the questions on the test if the student answers every question.</h3>

Step-by-step explanation:

Given that a multiple-choice test contains 10 questions and there are 4 possible answers for each question.

∴ Answers=4 options for each question.

<h3>To find how many ways  a student can answer the given questions on the test if the student answers every question :</h3>

Solving this by product rule

Product rule :

<u>If one event can occur in m ways and a second event occur in n ways, the number of ways of two events can occur in sequence is then m.n</u>

From the given the event of choosing the answer of each question having 4 options is given by

The 1st event of picking the answer of the 1st question=4 ,

2nd event of picking the answer of the 2nd question=4 ,

3rd event of picking the answer of the 3rd question=4

,....,

10th event of picking the answer of the 10th question=4.

It can be written as  by using the product rule

=4.4.4.4.4.4.4.4.4.4

=4^{10}

=1048576

<h3>∴ there are 1048576 ways a student can answer the questions on the test if the student answers every question.</h3>
