Answer:

Step-by-step explanation:

Solution by completing the square for:

x2−12x+9=0

Keep x terms on the left and move

the constant to the right side

by subtracting it on both sides

x2−12x=−9

Take half of the x term and square it

[−12⋅1/2]^2=36

then add the result to both sides

x^2−12x+36=−9+36

Rewrite the perfect square on the left

(x−6)^2=−9+36

and combine terms on the right

(x−6)^2=27

Take the square root of both sides

x−6=±27−−√

Simplify the Radical term (1):

x−6=±3–√3

Isolate the x on the left side and

solve for x (1)

x=6±3–√3

therefore (2)

x=6+3–√3

x=6−3–√3

which becomes

x=11.1962

x=0.803848

Answer:

−x2+2x−1=0

Step-by-step explanation:

To write an equation in standard form, move each term to the left side of the equation and simplify.

ax2+bx+c=0

Move 1

to the left side of the equation by subtracting it from both sides.

2x−x2−1=0

Reorder the polynomial.

−x2+2x−1=0

Answer and Step-by-step explanation:

Standard form of an equation is as follows:

Ax + By = C

We have 2x, -[tex]x^{2}[/tex], and a 1.

Subtract 1 from both sides.

[tex]-x^{2} + 2x - 1[/tex] = 0 is the equation in standard form.

Answer:

answer = cone

Step-by-step explanation:

just took the test and got it right! :)

The resulting three-dimensional object is a cone.

We have given that,

A triangular cross-section with coordinates at (1, 1), (1, 4), and (3, 1) is rotated about the line x = 1.

We have to determine what will be the resulting three-dimensional object.

A cone is a three-dimensional solid geometric shape having a circular base and a pointed edge at the top called the top.

A cone has one face and a vertex.

Therefore the first option is correct.

The resulting three-dimensional object is a cone.

Remark

Since we don't have anything other than the question, all I can do is answer the question. You are left with the task of figuring out the error.

Formula

Area = (central angle divided by 360 ) * pi r^2

Solution

Area = (40 /360) * 3.14 * 6^2

Area = 1/9 * 3.14 * 36

Area = 4 * 3.14

Area = 12.56

Answer:

slope = [tex]\frac{4}{5}[/tex]

Step-by-step explanation:

Calculate the slope m using the slope formula

m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]

with (x₁, y₁ ) = (- 3, 0 ) and (x₂, y₂ ) = (2, 4) ← 2 points on the line

m = [tex]\frac{4-0}{2-(-3)}[/tex] = [tex]\frac{4}{5}[/tex]

The difference in ages remains the same over time. Enoch, at twice Martin's age, is still 15 years older. That means Martin is 15 and Enoch is 30.

Given:

In triangle [tex]XYZ,m\angle X=90^\circ, m\angle Y=45^\circ, m\angle Z=45^\circ, XZ=y,YZ=15\sqrt{2}[/tex].

To find:

The value of y.

Solution:

In a right angle triangle,

[tex]\sin \theta =\dfrac{Perpendicular}{Hypotenuse}[/tex]

Using the above ratio for the triangle XYZ, we get

[tex]\sin Y =\dfrac{XZ}{YZ}[/tex]

[tex]\sin 45^\circ =\dfrac{y}{15\sqrt{2}}[/tex]

[tex]\dfrac{1}{\sqrt{2}}=\dfrac{y}{15\sqrt{2}}[/tex]

[tex]\dfrac{15\sqrt{2}}{\sqrt{2}}=y[/tex]

[tex]15=y[/tex]

Therefore, the correct option is C.

Answer:

(0, -5)

Step-by-step explanation:

The y-intercept of a graph is where the graph of the function intersects the y-axis. This means that the x-coordinate of the point is zero. To find the y-intercept of a line, when given the equation of the line, substitute (0) in for (x) and solve the equation,

y = x - 5

x = 0

y = 0 - 5

y = -5

This gives the resulting point of (0, -5) for the y-intercept of the line.

Answer:

It would have to be 6.  

Step-by-step explanation:

If it is an even amount in each bag, then there are only  6 red vines. So, if each bag needs a red a vine, then you can only make 6 bags.

6 candys are there in each bag and each bag has 3 lollipops, 2 tootsie and 1 red vine in each bag.

We have have 18 lollipops, 12 tootsie rolls, and 6 red vines then largest

amount of bags you can make with an even amount in each bag.

The LCM of two or more numbers is the smallest number that is evenly divisible by all numbers in the set.

The LCM of 18,12 and 6 is 6

Therefore 6 bags can be made

The number of lollipops in bag 18/6=3

The number of tootsie rolls in bag 12/6=2

The number of red vines in bag 6/6=1

Therefore 3 lollipops, 2 tootsie and 1 red vine in each bag

Answer:

New coordinates:

A = (-2, 1)

B = (0, 1)

C = (2, -3)

D = (0, -3)

Step-by-step explanation:

First, determine the ordered pairs for ABCD.

A = (2, 4)

B = (4, 4)

C = (6, 0)

D = (4, 0)

Horizontal movement will only affect the x coordinates of the ordered pairs. Horizontal movement includes moving to the right and left.

Vertical movement will only affect the y coordinates of the ordered pairs. Vertical movement includes moving up and down.

The question asks us to translate 4 units to the left. Moving left on the graph means we will subtract 4 from the x coordinates. The question also asks us to translate 3 units down. Moving down also means subtraction, but from the y coordinate.

New A = (2 - 4, 4 - 3) = (-2, 1)

New B = (4 - 4, 4 - 3) = (0, 1)

New C = (6 - 4, 0 - 3) = (2, -3)

New D = (4 - 4, 0 - 3) = (0, -3)

The new translation will have A at (-2, 1), B at (0, 1), C at (2, -3), and D at (0, -3).

Answer:

so the answer is 95°

Step-by-step explanation:

The two angles on a line add up to 180° or are supplementary, so we can find the inside angle x by doing 180-150=30°. Now that we know inside x is 30, if we add 30+65, we get 95, and 180-95=85°. Then to find angle xzw, just do 180-85 to get 95°.
