Answer:

x = 2[tex]\sqrt{2}[/tex]

Step-by-step explanation:

Using Pythagoras' identity in the right triangle.

The square on the hypotenuse is equal to the sum of the squares on the other 2 sides, that is

x² + (2[tex]\sqrt{2}[/tex] )² = 4²

x² + 8 = 16 ( subtract 8 from both sides )

x² = 8 ( take the square root of both sides )

x = [tex]\sqrt{8}[/tex] = 2[tex]\sqrt{2}[/tex]

Step-by-step explanation:

Answer:

70%

Step-by-step explanation:

Given data

Last years worth of vanishing potion= $82

This years worth of vanishing portion= $118

Note: Another way of asking this question is "what percent of $82 is $118"

So

=82/118*100

=0.69*100

=69%

=70% approx

Hence last years sale is 70% of this year's sales

Answer:

Converting y = -2x +5 to point-slope form will be:

Step-by-step explanation:

We know that the slope-intercept form of the line equation is

y = mx+b

where

Given the equation

[tex]y = -2x +5[/tex]

comparing with the  slope-intercept form

Slope of the line = m = -2

The y-intercept b = 5

We know that the value of y-intercept can be determined by setting x = 0, and determining the corresponding value of y.

Thus, the ordered pair or point representing the y-intercept will be:

Now, we have

Now, using the point-slope form of the line equation

[tex]y-y_1=m\left(x-x_1\right)[/tex]

where

substituting the values m = -2 and the point (x₁, y₁) = (0, 5)

[tex]y-y_1=m\left(x-x_1\right)[/tex]

[tex]y - 5 = -2(x-0)[/tex]

Therefore, converting y = -2x +5 to point-slope form will be:

Answer:multiply

Step-by-step explanation: How volume works is you multiply width times height times width. In perimeter you do the same but since in perimeter the shape is 2d you only have to multiply the base times height..........

Answer:

x=1

Step-by-step explanation:

Step 1: Subtract 3x from both sides.

x−10−3x=3x−12−3x

−2x−10=−12

Step 2: Add 10 to both sides.

−2x−10+10=−12+10

−2x=−2

Step 3: Divide both sides by -2.

−2x/−2 = −2/−2

x = 1

answer: B.5

i got the answers from the test

Answer:

b5

Step-by-step explanation:

Our point is (-5, -4)

Now use point slope form to find the equation: (y - y1) = m(x - x1)

(y - y1) = m(x - x1)

(y - (-4)) =-4/5(x - (-5))

y + 4 = -4/5x +4

An equation in slope-intercept form of the line is y = -4/5x - 8. The correct option is B.

An equation of the line is defined as a linear equation having a degree of one. The equation of the line contains two variables x and y. And the third parameter is the slope of the line which represents the elevation of the line.

The general form of the equation of the line:-

y = mx + c

m = slope

c = y-intercept

Slope = ( y₂ - y₁ ) / ( x₂ - x₁ )

Given that the slope −4/5 contains the point (−5,−4). The equation of the line is written as,

y = mx + c

-4 = -4/5 x - 5 + c

-4 = 4 + c

c = -8

The equation will be written as,

y = -4/5x - 8

Answer:

The method we could use is Combinations

Option B is correct option.

Step-by-step explanation:

We are given:

A car dealer is parking five new cars at his dealership.  Which of the following methods should be used to count the number of  possible ways to pick two cars to put in the showroom?

A)  permutations

B)  combinations

C) neither permutations nor combinations

First let us see, what is permutation and combinations.

Permutation

A permutation is defined as arranging the objects or numbers in a specific order.

Combinations

Combinations are defined as selecting the objects or numbers from a group  in such a way that the order of the objects is not important.

So, in the given question, we need to pick 2 cars and order of the cars is not important, so we can say that we could use Combinations

Option B is correct option.

Answer:

The correct option which best describes this method is:

Find half of 24 to calculate the radius. Then square the radius and multiply the result by [tex]\pi[/tex]

Option D is correct option.

Step-by-step explanation:

The circumference of table top = 24 [tex]\pi[/tex] inches

We need to find area of table top

The formula used to find area is: [tex]Area = \pi r^2[/tex]

We need to find radius of tabletop.

The formula used to find circumference is: [tex]Circumference = 2\pi r[/tex]

Putting value of circumference we can find radius

[tex]Circumference = 2\pi r\\24\pi =2\pi r\\r=\frac{24\pi}{2\pi}\\r=12[/tex]

So, radius of table top = 12

Now, finding the area:

[tex]Area = \pi r^2\\Area=\pi(12)^2\\Area=3.14(144)\\Area=452.16\:inches^2[/tex]

So, the correct option which best describes this method is:

Find half of 24 to calculate the radius. Then square the radius and multiply the result by [tex]\pi[/tex]

Option D is correct option.

Step-by-step explanation:

Answer:

B. vertical asymptote: x = 1

horizontal asymptote: y = 0

Step-by-step explanation:

1) Vertical asymptotes of a function are determined by what input of x makes the denominator equal 0. So, let's set the denominator, [tex]x^3-1[/tex], equal to 0 and solve for x:

[tex]x^3-1= 0\\x^3 = 1\\\sqrt[3]{x^3} = \sqrt[3]{1} \\x = 1[/tex]

Thus, the vertical asymptote is x = 1.

2) If the degree of the polynomial in the denominator is greater than the one on the top, the horizontal asymptote is automatically y = 0. Thus, the horizontal asymptote is y = 0.

Answer:

B. x=1, y=0

Step-by-step explanation:

Vertical asymptote: denominator approximate 0

(x²+x-6)/(x³-1)   ---> ±∞           as x ---> 1

x³-1 = 0

x³ = 1

x = ∛1 = 1

Horizontal asymptote: If the degree of the numerator is less than the degree of the denominator, then the horizontal asymptote is always the x axis, i.e. the line y = 0

degree of the numerator: 2

degree of the denominator: 3

2<3

Horizontal asymptote: y = 0

Answer:

x =+-1

Step-by-step explanation:

x^3+2x^2+x=x^3-x

(x^3-2x^2)-(x-2)=x(x^2-1)

x^2(x-2)-(x-2)=x(x^2-1)

(X^2-1)(x-2)=x(x^2-1)

(x+1)(x-1)(x-2)=x(x-1)(x+1)

(x+1)(x-1) ((x-2)-x)=0

-2(x+1)(x-1)=0

x =+-1

Answer:

They are the same

Step-by-step explanation:

The degree is basically all of the exponents added up. So:

A) 2+4 = 6

B) 2+3+1 = 6

(since x to the power of 1 is x)

So, they are the same
