Answer:

yes it can be bc it is repeating

Given that Point E is the midpoint of line segment YT, the numerical value of x is 2.

A midpoint is simply a point that divides a segment into two equal halves.

Given the data in the question;

Point E is the midpoint of line segment YT, YT is divided into two equal halves. Hence, Two times Line segment YE equals to YT.

2( Line segment YE ) = Line segment YT

Plug in the given values and solve for x.

2( Line segment YE ) = Line segment YT

2( 3x + 1 ) = 14

Expand using distributive property

2 × 3x + 2 × 1 = 14

6x + 2 = 14

Collect like terms

6x = 14 - 2

6x = 12

6x/6 = 12/6

x = 12/6

x = 2

Given that Point E is the midpoint of line segment YT, the numerical value of x is 2.

Using exponent properties, the equivalent expression is:

[tex]\frac{y^{18}}{z^{18}}[/tex]

The original expression is:

[tex]\left[\frac{y^{-3}z^5}{z^{-4}y^6}\right]^{-2}[/tex]

When two terms that are divided have the same base and different exponents, we keep the base and subtract the exponents, hence:

[tex]\left[\frac{y^{-3}z^5}{z^{-4}y^6}\right]^{-2} = [y^{-3 - 6}z^{5 - (-4)}]^{-2} = [y^{-9}z^9]^{-2}[/tex]

The negative exponent at the numerator goes to the denominator, hence:

[tex][y^{-9}z^9]^{-2} = \left[\frac{z^9}{y^9}\right]^{-2}[/tex]

The negative outer exponent means that we have to exchange the numerator and denominator, hence:

[tex]\left[\frac{z^9}{y^9}\right]^{-2} = \left[\frac{y^9}{z^9}\right]^{2}[/tex]

Then both numerator and denominator exponents multiply by 2, hence the equivalent expression is:

Answer:

Both sentences are false.

Step-by-step explanation:

Let's solve for x:

2x + 4y - 31 = 123

2x = 123 - 4y + 31

2x = 154 - 4y

x = 77 - 2y

Let's solve for y:

x = 77 - 2y

2y = 77 - x

y = 38.5 - 0.5x

Measure of angle 1 is 50° and that of angle 2 is 130°

The sum of all the angles on a straight line is equal to 180°.

Here, we are given two angles ∠1 and ∠2

Also, we are given that

m∠1 = (x+24)°

and m∠2 = 5x°

As we can see from the given figure, ∠1 and ∠2 lie on a straight line

⇒ m∠1 + m∠2 = 180

⇒ (x+24) + 5x = 180

x + 24 + 5x = 180

x + 5x + 24 = 180

6x + 24 = 180

6x = 180 - 24

6x = 156

x = 156/ 6

x = 26

Therefore,

m∠1 = 26 + 24

= 50

and m∠2 = 5(26)

= 130

Thus, the measure of the two angles is 50° and 130°

Step-by-step explanation:

The line passes through the points:

Since all x- coordinates are same, the line is vertical and its equation is:

Answer:

n = 18

Step-by-step explanation:

The sides in a regular polygon are equal in length.

⇒ BC = CD

If BC = CD then ΔDCB is an isosceles triangle.

As the base angles of an isosceles triangles are equal:

⇒ ∠DBC = ∠BDC = 10°

Interior angles in a triangle sum to 180°.

⇒ ∠DBC  +∠BDC + ∠DCB = 180°

⇒ 10° + 10° + ∠DCB = 180°

⇒ 20° + ∠DCB = 180°

⇒ ∠DCB = 180° - 20°

⇒ ∠DCB = 160°

Therefore, the interior angle of the regular polygon is 160°.

The interior angles of a regular polygon are equal in size.

[tex]\boxed{\begin{minipage}{5.2 cm}\underline{Interior angle of a polygon}\\\\$\dfrac{(n-2) \times 180^{\circ}}{n}$\\\\where $n$ is the number of sides.\\ \end{minipage}}[/tex]

To find the number of sides, equate the formula to the found value of the interior angle and solve for n:

[tex]\begin{aligned}\implies\dfrac{(n-2) \times 180^{\circ}}{n} & =160^{\circ}\\(n-2) \times 180^{\circ} & =n \times 160^{\circ}\\ 180(n-2) & = 160n\\180n-360 & = 160n\\180n & = 160n+360\\180n-160n & = 360\\20n & = 360\\n &= \dfrac{360}{20}\\n & =18\\\end{aligned}[/tex]

Therefore, the regular polygon has 18 sides.

The required function is d = 360 - 35h, 0 ≤ h ≤ 10.29.

We know that distance travelled is equalled to speed multiplied by time.

Let d be the distance from the destination.

Let d₁ be the distance travelled in h hour.

And h be the number of hours driven.

Given that the average speed is 35 miles per hour.

Therefore, we have d₁ = 35h

And the initial distance from the destination is 360 miles.

Note at time h= 0 the distance from the destination is the maximum which is 360 miles.

Therefore, we have d₁ = 35h

Distance from the destination is 360 - d₁.

⇒ d = 360 - d₁

⇒ d = 360 - 35h

Time taken to reach destination = d/v = 360/35 = 10.29 hours

Therefore the required function is d = 360 - 35h, 0 ≤ h ≤ 10.29

When the value of x = 1, the value of y = 729.

An inverse relationship is one where the value of one parameter decreases as the value of the second parameter increases. It is frequently described as a bad relationship.

Now, as per the question.

y varies inversely with the cube of x.

y ∝ 1/x³

Removing inverse, a constant of proportionality will come (say k)

y = k/x³

k = x³y.

When x = 9 then y = 1. Substitute the values and find k.

k = 9³(1)

k = 729

Now, estimate the value of y when x = 1.

y = k/x³ ( put the value of k and x )

y = 729/1³

y = 729

Thus, the value of y when the value of x = 1 is 729.

One of the boards is 30 inches long and the other board is 12 inches longer so it has to be 42 inches long. The sum of the lengths of the two boards is 72 cm and one of the boards is 12 inches longer than the other.

Here,

A board is 72 cm in length and must be cut so that one piece is 12 cm longer than the other piece .

We have to find the leg of each piece.

What is Length, Width and height?

The length, width and  height of an object are the different dimensions in linear units. length is the longest side of a shape, width is the shorter side, and height is the vertical dimension of the shape.

Now,

If you're going to cut the 72 inch board into two pieces, you can call one of the pieces x units long.

And, since the other piece is 12 inches longer than your first piece, its length is x + 12.

And, when you place these two pieces back together, their lengths should add up to be 72 inches.

You can write this last statement about adding the two pieces together to get a 72 inch piece

In equation form as:

x + (x+12) = 72

2x + 12 = 72

To solve this begin by subtracting 12 from both sides;

2x = 60

Now just divide both sides by 2 to find that:

x = 30

So, one of the boards is 30 inches long and the other board is 12 inches longer so it has to be 42 inches long. The sum of the lengths of the two boards is 72 cm and one of the boards is 12 inches longer than the other.

A differential equation with some initial conditions is used to solve an initial value problem.

The required particular solution is given by the relation:

[tex]$4y^{(3/2)} = 9e^{(-2x/3)} + 23[/tex]

An initial value problem in multivariable calculus is an ordinary differential equation with an initial condition that specifies the value of the unknown function at a given point in the domain. In physics or other sciences, modeling a system frequently entails solving an initial value problem.

Let the given equation be [tex]$y^{1/2} dy\ dx y^{3/2} = 1[/tex], y(0) = 9

[tex]$(\sqrt{y } ) y^{\prime}+\sqrt{(y^3\right\left) }=1[/tex] …..(1)

Divide the given equation (1)  by [tex]$\sqrt{ y} $[/tex]  giving

[tex]$y^{\prime}+y=y^{(-1 / 2)} \ldots(2)$[/tex], which is in Bernoulli's form.

Put [tex]$u=y^{(1+1 / 2)}=y^{(3 / 2)}$[/tex]

Then [tex]$(3 / 2) y^{(1 / 2)} \cdot y^{\prime}=u^{\prime}$[/tex].

Multiply (2) by [tex]$\sqrt{ } y$[/tex] and we get

[tex]y^{(1 / 2)} y^{\prime}+y^{(3 / 2)}=1[/tex]

(2/3) [tex]u^{\prime}+u=1$[/tex] or [tex]$u^{\prime}+(3 / 2) y=3 / 2$[/tex],

which is a first order linear equation with an integrating factor

exp[Int{(2/3)dx}] = exp(2x/3) and a general solution is
