Anyone know the answer to this question?

Answer:

Step-by-step explanation:

This doesn't factor. Not only that, but it does not give real results. The discriminate is negative.

a = 2

b = 4

c = 10

You could divide this equation by 2

a = 1

b = 2

c = 5  

These three are smaller and easier to calculate. The answer will be the same.

x = (- b +/- sqrt(b^2 - 4*a*c ) / (2 a)

x = (-2 +/- sqrt(^2 - 4(1)*(5) ) / 2*1

x = (-2 +/- sqrt(4 - 20) ) / 2

X = (-2 +/- sqrt(-16) ) /2

x = (-2 +/- 4i ) / 2

x = ( - 1) +/- 2i

Answer:

Step-by-step explanation:

We know there are 180° in EVERY triangle.  Given one angle is 58°

This triangle shown has two sides that are the same, both are 6.  The value of those two sides is irrelavent, except for the fact that this is an Isosceles triangle and the angle opposite those two sides are equal.

     x + x + 58 = 180

       2x + 58  = 180

           2x    = 180 -58

           2x = 122          

            x  =  61

Answer:

3.5.

Step-by-step explanation:

Zach's teammates were late to practice last week. According to Khan Academy the answer is 3.5.

The mean number of times Zach's teammates were late to practice last week is 3.5

A dot plot visually groups the number of data points in a data set based on the value of each point.

Given that, the following dot plot shows how many times each teammate was late to practice last week.

We need to find mean,

Total elements = 2 + 4 + 4 + 4 = 14

Data points = 4

Mean = 14 / 4 = 3.5

Hence, the mean number of times Zach's teammates were late to practice last week is 3.5

Answer:

1) m<2 = 115°

2) m<5 = 83°

3) m<8 = 45°

4) m<4 = 137°

Step-by-step explanation:

When two lines cross over each other, creating four angles, the opposite angles are equal.

So in question one, <1 is equal to <2, the angle opposite it, and so it is 115°.

Similarly, in question two, <5 = <6 = 84°.

In question three, <8 = <9 = 45°.

and in question four, <3 = <4 =137°.

Answer:

1) 115

2) 83

3) 45

4) 137

Step-by-step explanation:

Each problem is asking you to find the missing angle given its vertical angle.

Vertical angles are congruent therefore the angle given is the answer

Just in case that doesn't make sense here you go:

For #1 ∠1 and ∠2 are vertical angles

vertical angles are congruent ( equal to each other ) so if

∠1 = 115° then ∠2 = 115°

For#2 ∠5 and ∠6 are also vertical angles so they are congruent

so if ∠5 = 83° then ∠6 = 83°

For #3 ∠8 and ∠9 are vertical angles so they are congruent

so if ∠8 = 45° then ∠9 = 45°

For #4 ∠3 and ∠4 are vertical angles so they are congruent

So if ∠3 = 137° then ∠4 = 137°

Answer: 9^(x-3) = 9^3

Step-by-step explanation:

Realizing that 729 = 9^3, we can rewrite the equation ...

9^(x -3) = 729

as ...

9^(x -3) = 9^3 . . . . . . matches the second selection

__

Recognizing that 9 = 3^2, a couple of other equivalent forms can be made.

(3^2)^(x -3) = (3^2)^3

3^(2x-6) = 3^6

or, taking the square root, ...

3^(x -3) = 3^3

None of these forms match any answer choices.

Answer:

result = 15cm

Step-by-step explanation:

Hi! to can solve this, we have to keep in mind this formulas:

A1 = π [tex]r^{2}[/tex]                     ; where r = radius

A2 = (π [tex]r^{2}[/tex]) * (h)           ; where h= height

now  we solve:

first, we have to calculate the area of the circumference

A1 = [tex](3.14)*(4cm)^{2}[/tex] = [tex]50.24cm^{2}[/tex]

then, we already know the volume of the cylinder, and the area of the circumference, so we have to find just h of the second formula:

A2 = (π [tex]r^{2}[/tex]) * (h)  

h = 15cm

Answer:

Area = 13.8 cm²

Step-by-step explanation:

Area of a triangle = ½*base*height

base = 4 cm

height = ?

Find height using trigonometry function:

Reference angle = 60°

Opp = height = BC

Adj = 4 cm

Apply TOA:

Tan 60 = Opp/Adj

Tan 60 = BC/4

BC = 4*Tan 60

BC = 6.92820324 ≈ 6.9 cm

✔️Area of triangle = ½*4*6.9

= 13.8 cm²

Answer:

around 36 is the diameter

Step-by-step explanation:

C=2Pir or pi*d

113.04=pi*d

113.04/pi=d

d≈36

give me brainliest[tex]≈[/tex]

36 units is the diameter of the circle.

The perimeter of a two-dimensional form is the space surrounding it. It represents the total length of the shape's sides. The units used to measure the sides of the form, such as meters, centimeters, inches, or feet, determine the units used to measure the perimeter.

We can use the formula for the circumference of a circle, C = πd,

where C is the circumference and d is the diameter.

Substituting the given value, we have:

113.04 = πd

To solve for d, we can divide both sides by π:

d = 113.04/π

Using a calculator to evaluate this expression, we get:

d ≈ 36

Therefore, the diameter of the circle is approximately 36 units.

Answer:

I can't see the options, so i will find all the asymptotes.

We have the function:

[tex]f(x) = \frac{x^4 - 4*x^2 + x}{-2*x^4 + 18*x^2}[/tex]

First, we can graph this using a graphing tool, the graph can be seen below.

In the graph, we can see that when we approach x = 0 from the left, f(x) goes to negative infinity, while if we approach x = 0 from the right, f(x) goes to infinity.

This can be written as:

[tex]\lim_{x \to 0_-} f(x) = - \infty \\[/tex]

and:

[tex]\lim_{x \to 0_+} f(x) = + \infty \\[/tex]

A similar thing can be seen at x = 3, when we approach from the left f(x) goes to infinity, while if we approach from the left, f(x) goes to negative infinity.

Then:

[tex]\lim_{x \to 3_-} f(x) = \infty \\\\\lim_{x \to 3_+} f(x) = - \infty \\[/tex]

For x = -3 we can see that when we approach from the left, f(x) goes to negative infinity, while if we approach from the right, f(x) goes to infinity.

Then:

[tex]\lim_{x \to -3_-} f(x) = - \infty \\\\\lim_{x \to -3_+} f(x) = + \infty \\[/tex]

We also can see that as x goes to negative infinity or positive infinity, f(x) tends to -0.5

Then:

[tex]\lim_{x \to \infty} f(x) = -0.5 \\ \lim_{x \to -\infty} f(x) = -0.5[/tex]

So you need to check the options that match with some of the given tendencies.

The probability that a person texts over 50 messages per month given that the person is between the ages of 23 and 60 is 157/456.

Probability is a measure of the likelihood of an event to occur. Many events cannot be predicted with total certainty. We can predict only the chance of an event to occur i.e., how likely they are going to happen, using it.

Given is table showing the results of a survey on the number of text messages per month for people of different ages.

we need to find the probability that a person texts over 50 messages per month given that the person is between the ages of 23 and 60,

P(E) = favorable outcomes / total outcomes

Favorable outcomes = 157

Total outcomes = 456

Hence the required probability = 157 / 456

Hence the probability that a person texts over 50 messages per month given that the person is between the ages of 23 and 60 is 157/456.
