Finding m∠2 is c. 44°.

First step is to find the Measure of angle 1 which is m∠1

Measure of angle 1 = (68° + 68°) or (68°×2)

Measure of angle 1 = 136°

Second step is to find  m∠2

Since we have find the measure of angle 1 in order for us to find or determine m∠2 we would have to deduct or subtract m∠1 from 180°

Now let find m∠2

m∠1 = 136°

m∠1 + m∠2 = 180°

136° + m∠2 = 180°

m∠2 = 180° - 136°

m∠2 = 44°

Therefore finding m∠2 is c. 44°.

10 percent of the students failed in all three subjects.

Let the us assume that the total number of students in the school are 100.

Thus, according the the information given-

number of students who passed in all three subjects = 20

⇒ number of students who failed in at least one subject = 100 - 20 = 80

Let the number of people who failed in all three subjects be a

Then, as per the given information, we can make a venn diagram as shown in the figure below.

Now, the sum of all the terms in the venn diagram must be 80 since 80 people failed in at least 1 subject. Thus, we get the following equation-

a -3 + 35 - a + 25 - a + a + a - 4 + 15 - a + 2 + a = 80

a + 32 + 25 + 11 + 2 = 80

a + 70 = 80

a = 80 - 70

a = 10

Thus, the percentage of the students who failed in all 3 subjects will be-

10/100 × 100

= 10%

Hence, 10 percent of the students failed in all three subjects.

The set which represents whole numbers but are not natural numbers is:{0,1,2,3 }

Given, we have the following sets:

{₋2,₋3,₋4} = Integers

Negative numbers and all entire numbers are both considered integers. A number without a decimal or fractional element is known as an integer, which encompasses both positive and negative numbers, including zero.

{0,1,2,3} = whole numbers

Whole numbers refer to all natural numbers, including zero (0). We are aware that the term "natural numbers" refers to a group of counting numbers beginning with 1, 2, 3, and so forth. Simply said, a collection of numbers that are whole numbers are those that do not contain any fractions, decimals, or even negative integers. There are zeroes and a group of positive integers in it. whereas all positive integers from 1 to infinity are included in the number system, which also contains natural numbers, which are also used for counting. There is no zero included.

{√₋1 , √₋4 , √₋5 }= Irrational numbers

We are aware that the only numbers that cannot be stated in the form of p/q, where p and q are integers and q 0, are real numbers. For instance, the numbers √5, √3, and so on are irrational.

hence we get the set which represents whole numbers but not natural numbers is {0,1,2,,3,4}

Using t for the time in years since age 6 and H for height in inches, find a formula for H as a linear function of t.

After 7 years, the total amount accumulated is $13,691.43.

For the given question;

The formula for compound interest is;

CI = P(1 + r/n)∧nt

The rate rate of interest is according to APR; r = 4.4% = 0.044

P = principal amount ($5800).

t  = time in years (7 years)

n = number of times interest given per time period

n = 7×12 = 84 (as compounded monthly)

CI = 5800( 1 + 0.044/84)∧(84×7)

CI = 5800×(1.36)

CI = 7891.43

Thus, the total interest formed after 7 years.

Total amount in bank = principal amount + CI

                                   = 5800 + 7891.43

                                   = 13,691.43

Answer: no

Step-by-step explanation: hope this helps

I'll use x in place of θ

Let's isolate the sine term and then square both sides

3sin(x) + 4cos(x) = 5

3sin(x) = 5-4cos(x)

(3sin(x))^2 = ( 5-4cos(x) )^2

9sin^2(x) = 25-40cos(x)+16cos^2(x)

9sin^2(x) = 25-40cos(x)+16(1-sin^2(x))

9sin^2(x) = 25-40cos(x)+16-16sin^2(x)

9sin^2(x)+16sin^2(x) = 25-40cos(x)+16

25sin^2(x) = 41-40cos(x)

25(1-cos^2(x)) = 41-40cos(x)

25-25cos^2(x) = 41-40cos(x)

Now let w = cos(x), so we now have the following

25-25w^2 = 41-40w

25w^2-40w+41-25 = 0

25w^2-40w+16 = 0

(5w - 4)^2 = 0

5w-4 = 0

w = 4/5

Therefore cos(x) = 4/5

Use the pythagorean theorem or unit circle to find that if cos(x) = 4/5, then it leads to sin(x) = 3/5. This is exactly because of the 3-4-5 right triangle.

Then lastly,

tan(x) = sin(x)/cos(x)

tan(x) = sin(x)  ÷  cos(x)

tan(x) = (3/5)  ÷  (4/5)

tan(x) = (3/5)  *  (5/4)

tan(x) = (3*5)/(5*4)

tan(x) = 3/4

In quartic equation, The player will catch the ball on its way down, at about 4.346 seconds. .

What is the quartic equation's formula?

h  =  -16t2 + 70t + 4

We want to know how many seconds it takes for the ball to be 6 feet above the ground.

We want to know the value of  t  when  h = 6 .  So plug in  6  for  h  and solve for  t .

6  =  -16t2 + 70t + 4       Subtract  6  from both sides of the equation.

0  =  -16t2 + 70t - 2        Let's solve this quadratic equation using the quadratic formula.

t = -70 ± √70² - 4( -16)(-2)/2(-16)

t = -70 ± √4900 -128/ -32

t = -70 ± √4772/ -32

t = -70 + √4772/ -32 ≈ 0.029

t = -70 - √4772/ -32  ≈ 4.346

So we know that

(a) at 0.029 seconds, the ball is 6 feet above the ground and on its way up,  and

(b ) at 4.346 seconds, the ball is 6 feet above the ground and on its way down.
