[tex]\text{The angle from the right is 30}^\circ \\ \\ \text{We use sinus theorem:}\\\\ \dfrac{y}{\sin(60)^{\circ}} = \dfrac{8}{\sin(30)^{\circ}} \Rightarrow \dfrac{y}{\dfrac{\sqrt{3}}{2}} = \dfrac{8}{\dfrac{1}{2}} \Rightarrow y = \dfrac{\sqrt 3}{2}\cdot 16\Rightarrow \boxed{y = 8\sqrt 3}[/tex]

Answer:

y = 8[tex]\sqrt{3}[/tex]

Step-by-step explanation:

Using the tangent ratio in the right triangle and the exact value

tan60° = [tex]\sqrt{3}[/tex], hence

tan60° = [tex]\frac{opposite}{adjacent}[/tex] = [tex]\frac{y}{8}[/tex]

Multiply both sides by 8

8 × tan60° = y, so

y = 8[tex]\sqrt{3}[/tex] ← exact value

Answer:

Option C is false.

Step-by-step explanation:

The correct answer is:

C. Polynomials are closed under division. When you divide polynomials, the result will always be a polynomial.

This is false because sometimes when we divide polynomials, one polynomial does not gets completely or evenly divided by the other.  

In such cases, we get a remainder which is not a monomial as the variable has a negative power. This means the quotient is not a polynomial.

We can show this by example : suppose we want to divide

[tex]x^{-6}[/tex]by [tex]x^{2}[/tex]

=> [tex]\frac{x^{-6} }{x^{2} }[/tex]

=> [tex]x^{-6-2}[/tex] =>[tex]x^{-8}[/tex]

This is not a polynomial. So the closure property does not hold true for division of polynomials.

Answer:

[tex] x = \dfrac{5}{2} - \dfrac{\sqrt{37}}{2} [/tex]   and   [tex] y = \dfrac{5}{2} + \dfrac{\sqrt{37}}{2} [/tex]

[tex] x = \dfrac{5}{2} + \dfrac{\sqrt{37}}{2} [/tex]   and   [tex] y = \dfrac{5}{2} - \dfrac{\sqrt{37}}{2} [/tex]

Step-by-step explanation:

Let the numbers be x and y.

We now have a system of equations.

x + y = 5

xy = -3

Solve the second equation for x.

x = -3/y

Now substitute x in the first equation with -3/y.

-3/y + y = 5

Multiply both sides by y.

-3 + y^2 = 5y

y^2 - 5y - 3 = 0

Use the quadratic formula to solve for y.

[tex] y = \dfrac{-b \pm \sqrt{b^2 - 4ac}}{2a} [/tex]

[tex] y = \dfrac{-(-5) \pm \sqrt{(-5)^2 - 4(1)(-3)}}{2(1)} [/tex]

[tex] y = \dfrac{5 \pm \sqrt{25 + 12}}{2} [/tex]

[tex] y = \dfrac{5 \pm \sqrt{37}}{2} [/tex]

[tex] y = \dfrac{5 + \sqrt{37}}{2} [/tex]   or   [tex] y = \dfrac{5 - \sqrt{37}}{2} [/tex]

[tex] y = \dfrac{5}{2} + \dfrac{\sqrt{37}}{2} [/tex]   or   [tex] y = \dfrac{5}{2} - \dfrac{\sqrt{37}}{2} [/tex]

We get 2 solutions for y. Now for each solution for y, we need to find a corresponding solution for x.

Solve the first equation for x.

x + y = 5

x = 5 - y

Substitute each y value to find the corresponding x value.

[tex] x = 5 - (\dfrac{5}{2} + \dfrac{\sqrt{37}}{2}) [/tex]

[tex] x = 5 - \dfrac{5}{2} - \dfrac{\sqrt{37}}{2} [/tex]

[tex] x = \dfrac{10}{2} - \dfrac{5}{2} - \dfrac{\sqrt{37}}{2} [/tex]

[tex] x = \dfrac{5}{2} - \dfrac{\sqrt{37}}{2} [/tex]

This give one solution as:

[tex] x = \dfrac{5}{2} - \dfrac{\sqrt{37}}{2} [/tex]   and   [tex] y = \dfrac{5}{2} + \dfrac{\sqrt{37}}{2} [/tex]

Now we substitute the other y value to find the other x value.

[tex] x = 5 - (\dfrac{5}{2} - \dfrac{\sqrt{37}}{2}) [/tex]

[tex] x = 5 - \dfrac{5}{2} + \dfrac{\sqrt{37}}{2} [/tex]

[tex] x = \dfrac{10}{2} - \dfrac{5}{2} + \dfrac{\sqrt{37}}{2} [/tex]

[tex] x = \dfrac{5}{2} + \dfrac{\sqrt{37}}{2} [/tex]

This give the second solution as:

[tex] x = \dfrac{5}{2} + \dfrac{\sqrt{37}}{2} [/tex]   and   [tex] y = \dfrac{5}{2} - \dfrac{\sqrt{37}}{2} [/tex]

Answer:

Last Option

[tex]P (B) = 0.6[/tex]

Step-by-step explanation:

We have the Venn diagram that shows the probabilities of occurrence of 3 events A, B and C

In this case, since events A and B and B and C are non-disjoint events, then the probability of occurrence B is the sum of the probability that only B will occur plus the probability of occuring A and B plus the probability that B and C occur

This is:

[tex]P (B) = 0.1 +0.3 +0.2[/tex]

[tex]P (B) = 0.6[/tex].

Answer:

90 sq. ft.

Step-by-step explanation:

The formula you need to use is length*width*height. If you plug the numbers given into the equation, you get 5*3*6. Multiply this for the answer.

Answer:  The correct option is (B) 126 sq. feet.

Step-by-step explanation:  We are given to find the total area of the solid figure.

We can see that the given solid figure is a cuboid.

The total area of a cuboid with length l units, breadth b units and height w units is given by

[tex]A=2(lb+bh+hl).[/tex]

For the given cuboid, we have

length, l = 5 feet,

breadth, b = 3 feet and

height, h = 6 feet.

Therefore, the total area of the given cuboid will be

[tex]A=2(5\times 3+3\times6+6\times 5)=2(15+18+30)=2\times63=126~\textup{sq. feet}.[/tex]

Thus, the total area of teh solid figure is 126 sq. feet.

$3.468.15

I just subtracted 1.89% from $183,500

$3,468.15.

To calculate Patrick's annual property taxes on his new home, we need to apply the property tax rate of 1.89% to the value of the home. The formula to calculate this is:

Property Taxes = Home Value  imes Tax Rate

In this case, Patrick's home value is $183,500 and the tax rate is 1.89%. So, the calculation would be:

Property Taxes = $183,500 times 0.0189

When we perform this multiplication, we get:

Property Taxes = $3,468.15

Therefore, the property taxes on Patrick's new home are $3,468.15.

[tex]\frac{3}{8}[/tex] cups of oil

Step-by-step explanation:

Given : A recipe requires 1/4 cup of oil for every 2/3 cup of water.

To Find:  How much oil (in cups) is needed per cup of water?

Solution:

Oil required by [tex]\frac{2}{3}[/tex] cup of water = [tex]\frac{1}{4}[/tex]

Oil required by 1 cup of water = [tex]\frac{\frac{1}{4}}{\frac{2}{3}}[/tex]

                                                   = [tex]\frac{3}{8}[/tex]

Hence [tex]\frac{3}{8}[/tex] cups of oil is needed for per cup of water.

The oil required for one cup of water is 3/8 cup.

Given that a recipe requires 1/4 cup of oil for every 2/3 cup of water.

The quantities of oil and water are given in fractions. We can write as,

[tex]\dfrac {1}{4}cup \; oil = \dfrac {2}{3} cup\;water[/tex]

[tex]1 cup\;water = \dfrac {\dfrac {1}{4}cup\;oil}{\dfrac{2}{3}}[/tex]

[tex]1cup\;water = \dfrac {3}{8}cup\;oil[/tex]

Hence we can conclude that the oil required for one cup of water is 3/8 cup.

Given a straight line segment AB with points A, O, and B, and angle measures <COA, <COD, and <DOB, we find <COD to be 45 degrees using angle sum properties.

In the given scenario, we have a straight line segment AB, and points O, A, and B lying on it. We are required to find the measure of angle COD, denoted as <COD. According to the information provided, <COA is (3x + 94), <COD is (x + 36), and <DOB is (2x - 4).

Since A, O, and B are collinear, the sum of the angles around point O must be 180 degrees. Therefore, <COA + <COD + <DOB = 180 degrees. Substituting the given angle measures into the equation, we get:

(3x + 94) + (x + 36) + (2x - 4) = 180.

Combining like terms and solving for x:

6x + 126 = 180,

6x = 54,

x = 9.

Now that we have the value for x, we can find <COD by substituting it into the expression (x + 36):

<COD = 9 + 36 = 45 degrees.

Therefore, the measure of angle COD is 45 degrees.

Step-by-step explanation:

The amount by which the function is increasing from point to point is increasing, so it must be a quadratic or exponential function. If it was a quadratic, the amount it increases by would be increasing by a steady amount. (Ex. x^2 increases by how much it increased the last time + 2). But because this is not what the data shows, the function must be exponential.

The slope is 1

Step-by-step explanation:

The slope of the line is also its gradient. A gradient is basically rise/run

In this case the rise is one and the run is also one if you look at the graph...therefore 1/1 equals 1

Just by eyeballing the graph, you could see that the slope is 1: whenever x increases by 1, y will also increase by 1. Since the slope is defined as the ratio of the increments along the y and x axis, we have 1/1=1.

If you want to be more formal, you can pick any two points on the line, for example (0,1) and (3,4), and use the formula

Hello there!

An equation to model the number is: n - 7 x 2 = 2

To find the equation, break apart the question.

twice the difference of a number and 7 equals 2. - "Twice" means we are multiplying by 2, or x 2

twice the difference of a number and 7 equals 2. "The difference of a number and 7" means we are subtracting n - 7, and this is being multiplied by 2 so we have n - 7 x 2 so far.

twice the difference of a number and 7 equals 2. "Equals two" means the equation is equal to 2, or = 2, so our equation is n - 7 x 2 = 2.

The value of the number based on the information given is 8.

Let the number be represented by x.

Since we are given the equation that twice the difference of a number and 7 equals 2, the equation to solve this will be:

2(x - 7) = 2

2x - 14 = 2

2x = 2 + 14

2x = 16

x = 16/2

x = 8

The value of the number is 8
