Unit 8 Right Triangles And Trigonometry Homework 1

Answers

Answer 1

Answer:

x = 31.8

Step-by-step explanation:

From the picture attached,

By applying Pythagoras theorem in right ΔADC,

AC² = AD² + CD²

(22)² = AD² + (16)²

AD² = 484 - 256

AD = √228

     = 2√57

Now we apply Pythagoras theorem in right ΔADB,

AB² = AD² + DB²

x² = 228 + (44 - 16)²

x² = 228 + 784

x² = 1012

x = √1012

  = 31.81

  ≈ 31.8

Answer 2

The side x is an hypotenuse side to one of the right triangles formed by

altitude of the given triangle that has solid lines.

x is approximately 31.812

Reasons:

The figure shows a triangle with an altitude that forms two triangles inside

the main triangle.

By Pythagoras's theorem, we have;

For the right triangle on the left;

22² = h² + 16²

h² = 22² - 16² = 228

h² = 228

h = √228 = 2·√57

h = 2·√57

In the right triangle to the right, we have;

The length of the top base, b = 44 - 16 = 28

The square of the hypotenuse, x² = h² + b²

∴ x² = 228 + 28² = 1012

x = √(1012) = 2·√253

x = 2·√253 ≈ 31.812

You are given a penny on January 1, two pennies on January 2, four pennies on January 3, and eight pennies on January 4, and so on. 1.

Assuming the pattern continues, how many pennies do you get on the following dates? January 5 January 10 January 31

Answers

Answer:

january 5 :12

january 10:22

Step-by-step explanation:

Answer:

16 pennies512 pennies1073741824 pennies

Step-by-step explanation:

We can see a pattern:

Days >>   Pennies1        >>   1= 2^02        >>  2= 2^13       >>   4 = 2^24       >>   8 = 2^3...n       >>   2^(n-1)

So

January 5 fall on n = 5, therefore 2^4 = 16 penniesJanuary 10 falls on n = 10, therefore 2^9 = 512 penniesJanuary 31 falls on n = 31, therefore 2^30 = 1073741824 pennies

The mean volume for a bottle of cologne is 4 ounces and the standard deviation is 0.22 ounces. A random sample of 121 bottles is taken. What is the probability of obtaining a sample mean within 0.04 ounces of the population mean?

a. 0.9545
b. 0.0363
c. 0.3085
d. 0.5000

Answers

Answer:

The standard error of the mean is 0.02

Step-by-step explanation:

Here, we want to calculate the standard error of the mean.

Mathematically;

standard error of mean = SD/ √n

where SD is the standard deviation and n is the number of samples

From the question, SD = 0.22 and n = 121

Inserting this into the equation

Standard error of the mean = 0.22/√121

= 0.22/11 = 0.02

The probability of obtaining a sample mean is "0.9545".

According to the question,

Mean,

[tex]\mu = 4[/tex]

Standard deviation,

[tex]\sigma = 0.22[/tex]

Random sample,

[tex]n = 121[/tex]

By Central limit theorem,

→ [tex]\bar {x} \sim (4, \frac{0.22}{\sqrt{121} } )[/tex]

     [tex]= 0.2[/tex]

Now,

→ [tex]P(|\bar{x} - \mu| \ \alpha \ 0.04) = P(-0.04 \ \alpha \ \bar{x} - \mu \ \alpha \ 0.04)[/tex]

                               [tex]= P(\frac{-0.04}{0.02} \ \alpha \ z \ \alpha \ \frac{0.04}{0.02} )[/tex]

                               [tex]= P(-2 \ \alpha \ z \ \alpha \ 2)[/tex]

                               [tex]= 0.9545[/tex]

Thus the above response i.e., "option a" is appropriate.

Answer:
Submit Answer

Answers

Answer:

[tex] TV = 34 [/tex]

Step-by-step explanation:

WX = 23 – 2x,

TV = 64 – 10x,

First, create an equation you will use to find the value of x.

Thus:

[tex] WX = \frac{1}{2}(TV) [/tex] (midsegment theorem of a ∆)

[tex] 23 - 2x = \frac{1}{2}(64 - 10x) [/tex] (substitution)

[tex] 23 - 2x = \frac{1}{2}(64 - 10x) [/tex]

Multiply both sides by 2

[tex] (23 - 2x)*2 = \frac{1}{2}(64 - 10x)*2 [/tex]

[tex] 46 - 4x = 64 - 10x [/tex]

Collect like terms

[tex] 46 - 64= 4x - 10x [/tex]

[tex] -18= -6x [/tex]

Divide both sides by -6

[tex] 3 = x [/tex]

[tex] x = 3 [/tex]

Find TV:

[tex] TV = 64 - 10x [/tex]

Plug in the value of x

[tex] TV = 64 - 10(3) = 64 - 30 [/tex]

[tex] TV = 34 [/tex]

The math club is having a car wash to raise funds to attend a state competition. They need to raise a minimum of $325.00. The cost of supplies for the car wash is $25.00. If they expect 40 cars on the day of the car wash, what is the amount they will have to charge each car to meet the minimum goal?

Answers

Answer:

8.75

Step-by-step explanation:

the formula to use would be:

$325 = 40x - 25

add 25 to both sides of the equation to get:

$350 = 40x

divide both sides by 40 to get:

x = 350/40 = $8.75

if they charge $8.75 per car, they will raise 40 * that for a total of $350.

they would then subtract the $25 for the cost of the supplies and they would be left with $325.

that's their minimum goal.

8.75

The number of days, d, it will take Manny to read a book varles inversely as the number of pages, p, he reads per day. If kis the constant of
variation, which equation represents this situation?
OA. d+p=k
OB. dp = k
OC. d= pk
OD. d=p+k

Answers

I Believe B , If It’s Wrong I’m Sorry

The equation represents this situation will be dp = k. Thus, option B is correct.

What is directly proportional?

Let there are two variables p and q

Then, p and q are said to be directly proportional to each other if

p = kq

where k is some constant number called constant of proportionality.

The inversely proportional relationship is denoted by

[tex]m \propto \dfrac{1}{n} \\\\ \text{or} \\\\n \propto \dfrac{1}{m}[/tex]

As visible, increasing one variable will decrease the other variable if both are inversely proportional.

The number of days, d, it will take Manny to read a book varies inversely as the number of pages, p, he reads per day.

If k is the constant of variation.

The equation represents this situation will be

dp = k

Thus, option B is correct.

Desmond's monthly Netflix subscription costs $14.
If he charges it to his credit card each month for 7
months without making any payments, what will
his debt be?
Explain how you would solve this problem.
What is the answer?

Answers

Answer:

Desmond has a debt of $98.

Step-by-step explanation:

We are given that Desmond has a monthly Netflix subscription that charges him $14. Since it is a monthly subscription, it is a recurring charge.

We are also given that he does not make payments for 7 months. This means that the subscription is recurring for seven months.

Therefore, if he is charged $14 monthly and is charged that for 7 months, we can say that he is charged $14 seven times.

Therefore, we can create an equation that solved how much his debt would be based on this information.

[tex]\displaystyle14(7) = c\\\\14\times7=98\\\\c = 98[/tex]

Therefore, Desmond has a debt of $98.
