What is the value of x, and what is the missing angle?

NO LINKS, THEY WILL BE REMOVED

Answer:

x = 14

Missing angles: 33° and 57°

Step-by-step explanation:

(2x + 5) + (3x + 15) = 90° (complementary angles)

Add like terms

5x + 20 = 90

5x = 90 - 20

5x = 70

x = 70/5

x = 14

✔️Plug in the value of x to find each missing angle:

2x + 5 = 2(14) + 5 = 33°

3x + 15 = 3(14) + 15 = 57°

write an exponential formula of the form f (t)=a×b^t to represent the following situation. assume t is in years. an investment of $11,500 triples every 14 years. round your values to the three decimal places. f(t)=________

**Answer**

[tex]f(t) = 11500 * (3)^{\frac{t}{14}}[/tex]

**Explanation**

**Given**

[tex]a = 11500[/tex]** -- initial**

[tex]b = 3[/tex] ---- every 14 years

**Required**

The exponential equation

**The exponential equation is:**

[tex]y =ab^T[/tex]

**First, calculate the yearly rate.**

**Triples every 14 years, implies that:**

[tex]b = 3[/tex]** -- the rate**

[tex]T=\frac{t}{14}[/tex]** ---- time**

**So:**

[tex]y =ab^t[/tex]

[tex]y = 11500 * (3)^{\frac{t}{14}}[/tex]

**Hence:**

[tex]f(t) = 11500 * (3)^{\frac{t}{14}}[/tex]

Warren has a container which holds 22 books of the same shape and size. The exact breakdown of his books is shown below:

6 white books

9 purple books

7 green books

Each time, Warren takes out a book at random. He will replace the book and take out another book from the container. What is the probability that Warren takes out a green book in both draws? (3 points)

a

7 over 22 multiplied by 7 over 22 equal 49 over 484

b

7 over 22 multiplied by 6 over 21 equal 42 over 462

c

7 over 22 plus 6 over 21 equal 279 over 462

d

7 over 22 plus 7 over 22 equal 308 over 484

**Given:**

Total number of book = 22

Number of white books = 6

Number of Purple books = 9

Number of green books = 7

**To find:**

The probability that Warren takes out a green book in both draws (with replacement).

**Solution:**

We know that,

[tex]\text{Probability}=\dfrac{\text{Favorable outcomes}}{\text{Total outcomes}}[/tex]

[tex]P(\text{White})=\dfrac{6}{22}[/tex]

[tex]P(\text{Purple})=\dfrac{9}{22}[/tex]

[tex]P(\text{green})=\dfrac{7}{22}[/tex]

After replacement, the probability of event remains the same and the independent.

The probability that Warren takes out a green book in both draws is:

[tex]P=P(\text{green})\times P(\text{green})[/tex]

[tex]P=\dfrac{7}{22}\times \dfrac{7}{22}[/tex]

[tex]P=\dfrac{49}{484}[/tex]

**Therefore, the correct option is (a).**

Eli has $640 to spend at a bicycle store for some new gear and biking outfits. Assume all prices listed include tax.

He buys a new bicycle for $356.89.

He buys 2 bicycle reflectors for $16.70 each and a pair of bike gloves for $27.47.

He plans to spend some or all of the money he has left to buy new biking outfits for $74.08 each.

Write and solve an inequality which can be used to determine o, the number of outfits Eli can purchase while staying within his budget.

(write the equation that you used to solve this )

**Answer:**

**Step-by-step explanation:**

First of all we have to discover how much he spent.

356.89 + 2(16.70) + 27.47 = $417.76

Now we have to find how much money he saved

640 - 417.76 = $222.24

the total cost of biking outfits must be eqaua or less than $222.24..

We know the price of a single outift so we can write this inequality:

74.08o ≤ 222.24

we can find o by dividing the two members of the inequality:

o ≤ 222.24/74.08 = 3

o≤ 3

this mean that he can buy 1, 2 or 3 outfits

If f(x) = 3x - 1 and g(x) = x + 2, find (f+ g)(x).

**Answer:**

4x+1

**Step-by-step explanation:**

Since you're finding **(f+g) (x)**, it means you are adding f(x) and g(x) together.

so you add: (3x-1) and (x+2)

combining like terms, you get 4x and 1, which means **(f+g)(x)= 4x+1**

**Answer:**

(f + g)(x) = 4x + 1

**Step-by-step explanation:**

(f + g)(x) - f(x) + g(x) = 3x - 1 + x + 2 = 4x + 1

In science class, students are learning about organic compounds. An acetic acid

molecule is made of 2 carbon atoms, 2 oxygen atoms, and 4 hydrogen atoms.

What is the ratio of carbon atoms to all atoms in 2 molecules of acetic acid?

A 4:12

B 4:16

C 12:4

D 16:4

The answer is B) 4 : 16

Explanation:

RATIO FOR 1 MOLECULE OF ACETIC ACID:

2 carbon atoms : 2 oxygen atoms : 4 hydrogen atoms

Since its asking how many for 2 MOLECULES, we double the ATOMS (we multiply all by 2)

RATIO FOR 2 MOLECULES OF ACETIC ACID:

4 carbon atoms : 4 oxygen atoms : 8 hydrogen atoms

The question only asks for the ratio of carbon atoms to ALL atoms. To calculate all atoms, we add 4 + 4 + 8 = 16

So if there are 4 carbon atoms and the sum of all atoms is 16, out final ratio answer is:

B.) 4 : 16

Mark me brainliest please!!

Evaluate(8−3i)(3+2i)

**Answer:**

The answer is **30+7i.**

**Step-by-step explanation:**

Imaginary Number Definition

[tex]\large\boxed{{i=\sqrt{-1}}}[/tex]

Simply evaluate like how you evaluate polynomials. Expand the expression in.

[tex]\large{(8-3i)(3+2i)=[(8*3)+(8*2i)]+[(-3i*3)+(-3i*2i)]}\\\large{(8-3i)(3+2i)=(24+16i)+(-9i-6i^2)[/tex]

Therefore, our new expression when cancelling out the brackets is:

[tex]\large\boxed{24+16i-9i-6i^2}[/tex]

Imaginary Number Definition II

[tex]\large\boxed{i^2=-1}[/tex]

Therefore, substitute or change i² to -1

[tex]\large{24+16i-9i-6(-1)}\\\large{24+7i+6}\\\large{30+7i}[/tex]

Complex Number Definition

[tex]\large\boxed{a+bi}[/tex]

Where a = Real Part and bi = Imaginary Part.

Therefore, it's the best to arrange in the form of a+bi.

Hence, the answer is **30+7i**.

h(1)=-6 h(2)= 20 h(n)= h(n-2)+h(n-1) What is the value of h(3)?

9514 1404 393

**Answer:**

**Step-by-step explanation:**

Use the formula with n=3.

h(3) = h(3-2) +h(3-1)

h(3) = h(1) +h(2)

h(3) = -6 +20 . . . . . substitute the given values

find the area of the triangle with vertices(1,2),(2,3),and(4,5).what inference can you draw about the points from your upshot?

**Answer:**

(i) (-3/2, 3/2) and (1/2, - 3/2)

6x + 4y = - 3

(ii) Points are col linear

**Step-by-step explanation:**

Let the coordinates of the point(lower) be (a, b) and that of upper be (x, y).

Using mid point formula,

Mid point of diagonal(using the given points) is:

= ( (-2+1)/2 , (-1+1)/2) = (-½ , 0)

Using (a, b) and (x, y) :

= ( (a+x)/2 , (b+y)/2 ) = (-1/2, 0)

Which means, a+x= -1 & b + y = 0

Therefore, **x = - 1 - a ** & **b = - y **

Using distance formula, diagonal = √(-2-1)² + (-1-1)² = √13

Knowing the relation in diagonal and side, side = diagonal/√2 = √13/√2 = √(13/2)

Again using distance formula, diagonal = √13

=> √(x - a)² + (y - b)² = √13

=> (**-1-a** -a)² + (**-b **- b)² = 13

=> a² + b² + a = 3 **... (1) ** [**solved directly**]

Length of side = √(13/2)

=> √(a-(-2))² + (b-(-1))² = √(13/2)

=> a² + b² + 4a + 2b = 3/2 ** ...(2)**

On solving (1) and (2):

a = 1/2 or -3/2, but a lies in 4th quadrant so a > 0, thus, **a = 1/2 **

b = -3/2 or 3/2, but b lies in 4th quadrant so b < 0, **b = -3/2 **

Therefore,

**x = - 1 - a = -1 - 1/2 = -3/2 **

**y = - b = - (-3/2) = 3/2 **

Vertices are (x, y) = **(-3/2, 3/2) **and (a, b) =** (1/2, -3/2) **

Equation is just a relation in y and x, for a relation:

Subtract (1) from (2):

3a + 2b = -3/2 => 6a + 4b = - 3

By merely replacing a, b by x, y

**6x + 4y = ****-****3**** is the required equation **

(ii):

Ar. of ∆ = ½ | 1(3 - 5) + 2(5 - 2) + 4(2 - 3) |

Ar. of ∆ = ½ | -2 + 6 - 4 | = 0

As the area of the ∆ is 0, the given points don't form ∆, they are col linear.

A lawn service owner is testing new weed killers. He discovers that a particular weed killer is effective 89% of the time. Suppose that this estimate was based on a random sample of 60 applications. Construct a 90% confidence interval for p, the true proportion of weeds killed by this particular brand. what is the upper confidence limit for p

**Answer:**

The 90% confidence interval for p is (0.8236, 0.9564). The upper confidence limit for p is 0.9564.

**Step-by-step explanation:**

In a sample with a number n of people surveyed with a probability of a success of [tex]\pi[/tex], and a confidence level of [tex]1-\alpha[/tex], we have the following **confidence interval of proportions.**

[tex]\pi \pm z\sqrt{\frac{\pi(1-\pi)}{n}}[/tex]

**In which**

z is the zscore that has a pvalue of [tex]1 - \frac{\alpha}{2}[/tex].

**He discovers that a particular weed killer is effective 89% of the time. Suppose that this estimate was based on a random sample of 60 applications.**

This means that [tex]\pi = 0.89, n = 60[/tex]

**90% confidence level**

So [tex]\alpha = 0.1[/tex], z is the value of Z that has a pvalue of [tex]1 - \frac{0.1}{2} = 0.95[/tex], so [tex]Z = 1.645[/tex].

**The lower limit of this interval is:**

[tex]\pi - z\sqrt{\frac{\pi(1-\pi)}{n}} = 0.89 - 1.645\sqrt{\frac{0.89*0.11}{60}} = 0.8236[/tex]

**The upper limit of this interval is:**

[tex]\pi + z\sqrt{\frac{\pi(1-\pi)}{n}} = 0.89 + 1.645\sqrt{\frac{0.89*0.11}{60}} = 0.9564[/tex]

The 90% confidence interval for p is (0.8236, 0.9564). The upper confidence limit for p is 0.9564.

**Answer:**

Answer:

The 90% confidence interval for p is (0.8236, 0.9564). The upper confidence limit for p is 0.9564.

Step-by-step explanation:

In a sample with a number n of people surveyed with a probability of a success of , and a confidence level of , we have the following confidence interval of proportions.

The student body president of a high school claims to know the names of at least 1000 of the 1800 students who attend the school. To test this claim, the student government advisor randomly selects 100 students and asks the president to identify each by name. The president successfully names only 46 of the students. Identify the population and parameter of interest.

**Answer: **Population = Total students attend the school.

Parameter = Proportion of students named by president correctly.

**Step-by-step explanation:**

Population for a particular study is the largest possible group of individuals that are essential to be considered.

Parameter = measure of characteristic in a population.

By the above definition, we have

**Population = Total students attend the school(1800).**

**Parameter = Proportion of students named by president correctly.**

In [tex]\triangle[/tex] DEF, [tex]SinD = \frac{24}{26}[/tex] , then [tex]Cos \ E[/tex] will be equals to [tex]\frac{24}{26}[/tex] .

What are trigonometric ratios ?**Trigonometric ratios** are defined as the sides and angles of a right-angled triangle are dealt with in Trigonometry.

We have,

[tex]\triangle[/tex] DEF,

[tex]SinD = \frac{24}{26}[/tex]

We know that,

[tex]SinD=\frac{Perpendicular}{Hypotenuse}=\frac{EF}{ED}[/tex] and [tex]CosE=\frac{EF}{ED}[/tex]

Using Pythagoras Theorem,

[tex]P^{2} +B^{2} =H^{2}[/tex]

i.e.

[tex]EF^2+FD^2=EF^2[/tex]

[tex]24^{2} +FD^2=26^2[/tex]

[tex]FD^2=676-576[/tex]

[tex]FD=10[/tex]

But when we look from [tex]\angle E[/tex] for [tex]Cos E[/tex] then,

[tex]CosE=\frac{EF}{ED}[/tex]

so,

[tex]CosE=\frac{24}{26}[/tex]

So, the value of [tex]CosE=\frac{24}{26}[/tex] is derived using the **Trigonometric ratios.**

Hence, we can say that In [tex]\triangle[/tex] DEF, [tex]SinD = \frac{24}{26}[/tex] , then [tex]Cos \ E[/tex] will be equals to [tex]\frac{24}{26}[/tex] .
