Answer:

y=-5/3x+1

Step-by-step explanation:

The answer is y=-5/3x+1 because you would do the exact opposite of rise over run where it rises 5 units up and 3 units shifted right but instead it is still 3 units that are shifted to the right but 5 units down.  We can also assume that the y-intercept is 1 based on where the slope is placed.

Answer:

The value of x = 4

so

Step-by-step explanation:

We know that an angle bisector bisects the angle into two equivalent angles.

When BD bisects angle ABC, it forms two equivalent angles which are:

such as

m∠ABD = m∠CBD

as

m ∠ABD = 6x-8

m∠CBD = 3x+4

so the equation becomes

m∠ABD = m∠CBD

6x-8 = 3x+4

6x - 3x = 4 + 8

3x = 12

Divide both sides by 3

x = 4

Thus, the value of x = 4

Answer:

About 42 cents

Step-by-step explanation:

What we know:

An 18-count variety pack of Taki's chips costs $7.49.

To find the unit rate divide 7.49 by 18, and round to the nearest cent.

7.49/18

Before we do that, what is 749/18?

749/18 = 41 11/18

Divide that by 100 to get your answer

41.61111/100 = 0.4161111, which rounds to 42 cents.

Step-by-step explanation:

In the given triangle, we have

[tex]\tan(\theta) = \dfrac{20}{15} = \dfrac43[/tex]

Recall that

[tex]\sin^2(\theta) + \cos^2(\theta) = 1 \implies \tan^2(\theta) + 1 = \sec^2(\theta)[/tex]

Solving for [tex]\sec(\theta)[/tex], we have

[tex]\sec(\theta) = \sqrt{\tan^2(\theta) + 1} = \sqrt{\left(\dfrac43\right)^2 + 1} = \sqrt{\dfrac{25}9} = \boxed{\dfrac53}[/tex]

Answer:

-4(x-4)²+9y(y+4)=0

Step-by-step explanation:

If we put the -64 with the x’s instead of the y’s, we get:

-4x²+32x-64+9y²+36y=0

-4(x²-8x+16)+9y(y+4)=0

-4(x-4)²+9y(y+4)=0

For x = 0.33, the events G and H are mutually exclusive.

Here, we are given that-  

P(G) = 0.4

P(H) = x

and P(G or H) = 0.73

⇒ P(G∪H) = 0.73

Now, we know that-

P(G U H) = P(G) + P(H) - P(G ∩ H)

For any two events that are mutually exclusive, the probability that they occur at the same time is 0. Hence, if G and H are mutually exclusive, then P(G ∩ H) will be 0

⇒ 0.73 = 0.4 + x - 0

x = 0.73 - 0.4

x = 0.33

Thus, for x = 0.33, the events G and H are mutually exclusive.

An expression that represents a cube root of -8 is [tex]2(cos(\frac{\pi}{3} )+i~sin(\frac{\pi}{3} ))[/tex]

For a complex number z = a + ib, the trigonometric form is  [tex]r(cos\theta +isin\theta)[/tex]

where [tex]r=|\sqrt{a^{2} +b^{2} } |[/tex] and [tex]\theta=tan^{-1}(\frac{b}{a} )[/tex]

For given question,

We need to find the cube root of -8

[tex]\sqrt[3]{-8}[/tex]

We can write above number as complex number.

[tex]\sqrt[3]{-8}\\ =\sqrt[3]{8\times (-1)}\\ =\sqrt[3]{8}\times \sqrt[3]{-1}\\ =2 \times(-1)^\frac{1}{3}[/tex]

Consider a complex number z = -1

We can write -1 in trigonometric form as, [tex]-1=cos(\pi)+isin(\pi)[/tex]

We know, [tex](cos\theta +isin\theta)^{\frac{1}{n} }=(cos(\frac{1}{n} \theta )+isin(\frac{1}{n} \theta))[/tex]

So,

[tex](-1)^{\frac{1}{3} }\\\\=(cos\pi+i~sin\pi)^{\frac{1}{3} }\\\\=cos(\frac{\pi}{3} )+i~sin(\frac{\pi}{3} )[/tex]

Therefore, an expression that represents a cube root of -8 is [tex]2(cos(\frac{\pi}{3} )+i~sin(\frac{\pi}{3} ))[/tex]

Step-by-step explanation:

Answer:

Solution is the 5fx+45gx

(5.2,7.6)

mean=6.4

standard deviation=0.6

we have to find the range in which at least 75% of the data will reside

1-1/k²=0.75

1/k²=1-0.75

1/k²=0.25

k²=1/0.25=4

k=2

so, k=2

The range of values can be computed as mean±k(standard deviation).

Thus, the range in which at least 75% of the data will reside is

(mean-k(standard deviation), mean+ k(standard deviation))

Answer:

A

Step-by-step explanation:

From looking at the graph, you can see that the center point of the circle is at (5, -3), so to figure out the diameter, you need to find the distance of that line ( y = - 3 ) that the circle is on. The diameter is about 6 point something which in the square root form can be represented by √36.

After knowing the diameter is about 6, choice C can be eliminated.

2√10 = √40

4√10 = √160

2√34 = √136

After expanding the square root, we can know that the closest option is A.

Check the picture below.

so we know the circle has that center and passes through (2 , -2), let's find its radius, keeping in mind that diameter = 2 * radius.

[tex]~~~~~~~~~~~~\textit{distance between 2 points} \\\\ (\stackrel{x_1}{2}~,~\stackrel{y_1}{-2})\qquad (\stackrel{x_2}{5}~,~\stackrel{y_2}{-3})\qquad \qquad d = \sqrt{( x_2- x_1)^2 + ( y_2- y_1)^2} \\\\\\ \stackrel{radius}{r}=\sqrt{(~~5 - 2~~)^2 + (~~-3 - (-2)~~)^2} \implies r=\sqrt{(5 -2)^2 + (-3 +2)^2} \\\\\\ r=\sqrt{( 3 )^2 + ( -1 )^2} \implies r=\sqrt{ 9 + 1 } \implies r=\sqrt{ 10 }~\hfill \underset{diameter}{\stackrel{(2)(r)}{2\sqrt{10}}}[/tex]

Using proportions, the amounts you have of each block are given as follows:

A proportion is a fraction of a total amount, and the measures are related using a rule of three. Due to this, relations between variables, either direct(when both increase or both decrease) or inverse proportional(when one increases and the other decreases, or vice versa), can be built to find the desired measures in the problem, or equations to find these measures.

From the amounts given, you can create the following ratio:

Blue : Yellow : Orange : Red

6 : 4 : 1 : 0.25.

Hence the fractions corresponding to each color are given as follows:

Hence the number of blue blocks is found as follows:

6/11.25 x 47964 = 25,581.

The number of yellow blocks is given by:

4/11.25 x 47964 = 17,054.

The number of orange blocks is given by:

1/11.25 x 47964 = 4,263.

The number of red blocks is given by:

0.25/11.25 x 47964 = 1,066.
