Answer:

The lenght is 8 cm

Step-by-step explanation:

Answer:

8 cm.

Step-by-step explanation:

The area of the square base = volume / height

= 960/15

= 64 cm^2.

So the length of each side of the square base = √64

= 8 cm.

Answer:

m arc AJ = 78°

Step-by-step explanation:

If angle A is 101° that means arc LKJ is 202° (the measure of an arc that an inscribed angle intercepts is twice the angle measure).  If arc LKJ is 202° and arc LK is 122°, then arc KJ is 80° (m arc LK + m arc KJ = m arc LKJ).

If angle L is 79°, then the m arc AJK = 158° (the measure of an arc that an inscribed angle intercepts is twice the angle measure). If m arc AJK = 158° and m arc KJ is 80°, then the m arc AJ is 158 - 80 = 78º

The coordinates of D'E'F' after reflection are,

D' = (0, - 3)

E' = (1, 0)

F' = (2, - 1)

We have to given that,

Triangle DEF has vertex coordinates D(0, -3), E(-1,0), and F(-2,-1).

Here, Triangle DEF is reflected across the y-axis.

The rule for a reflection over the y -axis is,

(x, y) → (- x, y)

Hence, the coordinates of D'E'F' after reflection is,

D' = (0, - 3)

E' = (- (- 1), 0) = (1, 0)

F' = (- (- 2), (- 1)) = (2, - 1)

Step-by-step explanation:

Let's see. There is a missing side. Let's call that x. However, we know what the other sides are!

This is how we do it.

We know the largest side's length., 172.

Since we know the other sides, we can subtract their length from 172.

172-57-51-31=33

x=33

So now add the sides!

"An  interval is a set of real numbers that contains all real numbers lying between any two numbers of the set."

In the given graph,

A is the interval(0, 2) where the graph is linear increasing.

B is the interval(2, 4) where the graph is constant.

C is the interval(4, 5) where the graph is linear decreasing.

D is the interval(5, 8) where the graph is linear increasing.

Answer:

x=15(1/3√y)

Step-by-step explanation:

X varies indirectly with the cube root of y

x=k/3√y

x=3 when y=125

3=k/3√125

3=k/5

3=k(1/5)

k=3÷1/5

k=3×5/1

k=15

x=15(1/3√y)

Answer:

Step-by-step explanation:

The given lines are

[tex]2x-4y=8[/tex]

[tex]4x+2y=8[/tex]

Let's rewrite each equation in the form [tex]y=mx+b[/tex]

[tex]2x-4y=8\\2x-8=+4y\\y=\frac{2x-8}{4} \\y=\frac{x}{2}-2[/tex]

[tex]4x+2y=8\\2y=8-4x\\y=\frac{8-4x}{2}\\ y=4-2x[/tex]

Now, let's use the perpendicular rule

[tex]m_{1} \times m_{2} =-1\\\frac{1}{2} \times (-2)=-1 \implies -1=-1[/tex]

As you can observe, the slopes satisfy the perpendicular rule, that means the lines are perpendicular.

Therefore, the right answer is the second choice because it states the rule of perpendicularity between the given lines.

Options B, C, and D are the correct answer.

In mathematics and geometry, an angle is a measure of the amount of rotation or turn between two lines or line segments that meet at a common endpoint, called the vertex of the angle.

Angles are typically measured in degrees (°) or radians (rad).

A full rotation around a point is 360 degrees or 2π radians.

We have,

An angle is a measure of the amount of rotation or turn between two lines or line segments that meet at a common endpoint, called the vertex of the angle.

Arc length is the distance along the curve of a circle or any other curved shape. It is defined as the length of the portion of the circumference of a circle or a portion of a curve between two endpoints, measured along the arc of the curve.

From the diagram,

XZ and XY are arc lengths.

∠ZXY is an angle.

[tex] \dfrac{53}{8} [/tex]

Step-by-step explanation:

[tex] \dfrac{5}{8} = \dfrac{x - 1}{9} [/tex]

Cross multiply.

[tex]8(x - 1) = 9 \times 5[/tex]

[tex] 8x - 8 = 45 [/tex]

[tex] 8x = 53 [/tex]

[tex] x = \dfrac{53}{8} [/tex]

Answer: x = 53/8

Step-by-step explanation:

5/8 = x-1 / 9

45 = 8(x-1)

45 = 8x - 8

-8x = -8 - 45

x = 53/8

Answer:

The numbers are 72 and 96.

Step-by-step explanation:

LCM + GCF = 312

LCM - GCF = 264

2*LCM = 576

LCM = 576/2 = 288

HCF = 312–288 = 24

The product of two numbers = HCF*LCM

Let the numbers be x and (168-x)

x(168-x) = 24*288 = 6912

x^2–168x+6912 = 0

x = [168 +(168^2 -4*6912)^0.5]/2

= [168 +(28224–27648)^0.5]/2

= [168 + 576^0.5]/2

= (168+24}/2

= 192/2

= 96 and the other number is 168–96 = 72.

Answer: The sum of the interior angles of a polygon shown  in the picture is [tex]540^{\circ}[/tex].

Step-by-step explanation:

The given polygon is a regular pentagon having 5 sides.

The sum of the interior angles of a regular polygon is given by :-

[tex](n-2)\times180^{\circ}[/tex], wherer n= number of sides of the regular polygon.

Since it has 5 sides, then the sum of the interior angles of a polygon would be

[tex](5-2)\times180^{\circ}\\\\=3\times180^{\circ}\\\\=540^{\circ}[/tex]

Hence, the sum of the interior angles of a polygon shown  in the picture is [tex]540^{\circ}[/tex].

Answer:

Step-by-step explanation:

You'll need to use parentheses here to remove ambiguity regarding what's in your denominators:

          x - 8                   x - 8

y = ------------------  =  -----------------

      x^2 + 6x - 7        (x + 7)(x - 1)

This last result becomes undefined at x = -7 and x = 1, and thus its graph is discontinuous at those x- values.

The points of discontinuity is x = -7, x = 1

Use parentheses to remove ambiguity considering the denominators

[tex]y=x-8/x^{2} +6x-7[/tex]

= x-8 ÷ (x+7)(x-1)

The result becomes undefined at x = -7

and x = 1,  

thus its graph is discontinuous at those x values.

Therefore the points of discontinuity is x =-7 and x = 1.

[tex]V=150cm^3[/tex]

Step-by-step explanation:

First we need to find area of the triangle with a base of 4 cm and a height of 5cm, and then multiply that by the length of the prism of 15cm.

The area of the triangle is given by the  formula:

[tex]A_T=\frac{bh}{2}[/tex]

where b is the base: [tex]b=4cm[/tex] and h is the height: [tex]h=5cm[/tex]

thus, in this case we have:

[tex]A_T=\frac{(4cm)(5cm)}{2}\\ \\A_T=\frac{20cm^2}{2} \\\\A_T=10cm^2[/tex]

And now, the volume will be the area of the triangle multiplied by the length [tex]l=15cm[/tex] of the prism:

[tex]V=A_T*l[/tex]

Substituting the known values:

[tex]V=10cm^2*15cm\\V=150cm^3[/tex]

The volume in cubic centimeters is 150.
