Answer:

25.12 in³

Step-by-step explanation:

v = (1/3)πr²h

Plug in the givens

v = (1/3)(3.14)(4/2)²(6)

v = (1/3)(3.14)(4)(6)

v = 25.12

Answer:

m∠BPD: 120°

mBC + mAD =120°

Step-by-step explanation:

A figure which is formed by two rays or lines that shares a common endpoint is called an angle.

Given:

mBD =70°

mCA = 170°

So,

m∠BPD= 1/2( (m∠BD + m∠CA))

=1/2(170+70)

=1/2*240

=120

and,

mBC + mAD = 360 - ( 70 + 170 )

                    = 360 - 240

mBC + mAD = 120°

Answer:

x = 13

Step-by-step explanation:

The 2 angles same- side interior angles and sum to 180°

Then the equation to use to find x is

12x - 29 + 4x + 1 = 180

16x - 28 = 180 ( add 28 to both sides )

16x = 208 ( divide both sides by 16 )

x = 13

Answer:

13

Step-by-step explanation:

Angles ( 12x - 29 ) and ( 4x + 1 ) are co - interior angles.

Sum of co - interior angles are supplementary.

12x - 29 + 4x + 1 = 180

12x + 4x - 29 + 1 = 180

16x - 28 = 180

16x = 180 + 28

16x = 208

x = 208 / 16

x = 13

Answer:

[tex] \displaystyle 2 {x}^{2} + 4x - 30 = 0[/tex]

Step-by-step explanation:

we are given the zeros and a point where it goes through of a quadratic equation

remember that when the roots are given then the function should be

[tex] \displaystyle \: y = a(x - x_{1})(x - x_{2}) [/tex]

where a is the leading coefficient and x1 and x2 are the roots

substitute:

[tex] \displaystyle y = a(x - (3))(x - ( - 5)) [/tex]

simplify:

[tex] \displaystyle y = a(x - 3)(x + 5) [/tex]

now the given point tells us that when x is 2 y is -14 therefore by using the point we can figure out a

substitute:

[tex] \displaystyle a(2 - 3)(2 + 5) = - 14[/tex]

simplify parentheses:

[tex] \displaystyle a( - 1)(7) = - 14[/tex]

simplify multiplication:

[tex] \displaystyle - 7a = - 14[/tex]

divide both sides by -7:

[tex] \displaystyle a = 2[/tex]

altogether substitute:

[tex] \displaystyle y = 2(x - 3)(x + 5) [/tex]

since it want the equation y should be

[tex] \displaystyle 2(x - 3)(x + 5) = 0[/tex]

recall quadratic equation standard form:

[tex] \displaystyle {ax}^{2} + bx + c = 0[/tex]

so simplify parentheses:

[tex] \displaystyle 2( {x}^{2} + 2x - 15 ) = 0[/tex]

distribute:

[tex] \displaystyle 2 {x}^{2} + 4x - 30 = 0[/tex]

hence,

the equation of the parabola in standard form is 2x²+4x-30=0

Answer:

105

Step-by-step explanation:

The sum of the opposite interior angles of a triangle is equal to the exterior angle

25+80 = ?

105 = ?

Answer:

105

Step-by-step explanation:

The missing angle is supplementary to the missing inside angle of the triangle shown.

to find the missing angle in the triangle, set up your formula as

180=25+80+x

180-25-80=x

75=x

The missing angle is then 180-75=105

Answer:

B. 178

Step-by-step explanation:

x - 76 = 102

x - 76 + 76 = 102 + 76

x = 178

Answer:

[tex]x = 178[/tex]

Step-by-step explanation:

Rearrange unknown terms to the left side of the equation: [tex]x = 102 + 76[/tex]

Calculate the sum or difference: [tex]x = 178[/tex]

Answer: [tex]x = 178[/tex]

Answer:

Step-by-step explanation:

Answer:

[tex] \frac{8}{2} (2 + 2) = 16[/tex]

Given:

The factors of the quadratic function g(x) are (5x-1) and (x+4).

To find:

The solutions to the equation g(x)=0.

Solution:

If the factors of the quadratic function g(x) are (5x-1) and (x+4), then the function is defined as:

[tex]g(x)=(5x-1)(x+4)[/tex]

We need to find the solutions to the equation g(x)=0. So,

[tex]g(x)=0[/tex]

[tex](5x-1)(x+4)=0[/tex]

Using zero product property, we get

[tex]5x-1=0[/tex] and [tex]x+4=0[/tex]

[tex]x=\dfrac{1}{5}[/tex] and [tex]x=-4[/tex]

Therefore, the solutions to the equation g(x)=0 are [tex]x=\dfrac{1}{5}[/tex] and [tex]x=-4[/tex].

Step-by-step explanation:

but this time put context

Step-by-step explanation:

Square both sides and you will get

3xy/(x + y) = 4

Multiplying both by (x + y), we get

3xy = 4(x + y) = 4x + 4y

Put all the terms containing y to the left side:

3xy - 4y = 4x

y(3x - 4) = 4x

or y = 4x/(3x - 4)
