The right circular cylinder represented below has a base radius of
3 centimeters and a height of 12 centimeters.
12 cm
3 cm
the right circular cylinder in cubic
Answer:
108π
Step-by-step explanation:
volume of a cylinder = πr²h , where r = radius and h = height
given values
radius = 3height = 12==> plugging in given values into formula
V = πr²h
r = 3 , h = 12
V = π(3²)(12)
==> evaluate exponent
V = π(9)(12)
==> multiply 9 and 12
V = 108π
What are the solutions of the equation y = -2x square + 9x - 4
Answer:
x = (-1±i√3)/2
Step-by-step explanation:
y = -2x² + 9x - 4
x = (-b±√(b²-4ac))/2a
x = (2±√((-2)²-4(-1)(-4))/2(-2)
x = (2±√(4-16))/-4
x = (2±√-12)/-4
√-12 = √12 x √-1
√12 = √4√3
2i√3
x = (-1±i√3)/2
solve by completing the square
Step-by-step explanation:
[tex] {x}^{2} + 2x - 2 = 0[/tex]
Now Adding three on both sides we get
[tex]{x}^{2} + 2x - 2 + 3 = 0 + 3[/tex]
[tex] {x}^{2} + 2x + 1 = 3[/tex]
[tex] {(x + 1)}^{2} = 3[/tex]

1. Are the side lengths congruent?
2. Are the opposite sides parallel?
3. Are the adjacent sides perpendicular?
4. The most specific name for this quadrilateral is:
Answer:
opposite sides are congruentopposite sides are paralleladjacent sides are not perpendicularthe figure is a parallelogramStep-by-step explanation:
An easy way to determine the nature of the quadrilateral is to look at the lengths and midpoints of the diagonals. Adding and subtracting the coordinates of one end point from the other can tell what you need to know.
The diagonals of a parallelogram are mutual bisectors. The diagonals of a rhombus are perpendicular. The diagonals of a rectangle are congruent.
__
diagonal ACThe difference of end points of diagonal AC is ...
C -A = (7, 2) -(-6, 1) = (13, 1)
The sum of the end points of diagonal AC is ...
C +A = (7, 2) +(-6, 1) = (1, 3)
diagonal BDThe difference of end points of diagonal BD is ...
B -D = (0, 7) -(1, -4) = (-1, 11)
The sum of end points of diagonal BD is ...
B +D = (0, 7) +(1, -4) = (1, 3)
comparison of diagonalsmidpoints
The two diagonals have the same end point sum, (1, 3), meaning their midpoints are coincident. The figure is a parallelogram.
lengths
The lengths of the diagonals will be the same if the sum of squares of the coordinates of the end-point differences are the same.
Σ(C -A)² = 13² +1² = 170
Σ(B -D)² = (-1)² +11² = 122 ≠ 170 . . . . . not a rectangle
perpendicularity
The diagonals will be perpendicular if the "dot product" of the end-point differences is zero.
x1·x2 +y1·y2 = 13(-1) +1(11) = -2 ≠ 0 . . . . not a rhombus
The most specific name for this quadrilateral is parallelogram.
_____
Opposite sides of a parallelogram are congruent and parallel.
Adjacent sides of a rectangle are perpendicular. This is not a rectangle, so adjacent sides are not perpendicular.
A parallelogram that is not a rectangle or rhombus is described most specifically as a parallelogram.
Find the vertex of the parabola y=x^2 + 5x + 10
The coordinates of the vertex of the given parabola [tex]y=x^2+5x+10[/tex] will be [tex](\dfrac{5}{2},\dfrac{15}{4})[/tex].
What is the vertex of a parabola?Vertex of the parabola is the point of intersection of symmetry axis of the parabola and the parabola itself.
The given equation of parabola is [tex]y=x^2 + 5x + 10[/tex].
To get the coordinates of vertex of this parabola, we have to write the equation of parabola in the standard form.
So, write the equation of parabola in its standard form as,
[tex]y=x^2 + 5x + 10\\y=x^2+2\times \dfrac{5}{2}x+\dfrac{25}{4}-\dfrac{25}{4}+10\\y=(x-\dfrac{5}{2})^2+\dfrac{15}{4}\\(y-\dfrac{15}{4})=(x-\dfrac{5}{2})^2[/tex]
The standard form of parabola is,
[tex]y-b=(x-a)^2[/tex] where (a, b) is the coordinate of the vertex.
So, by comparing the equations, the vertex of the parabola will be [tex](\dfrac{5}{2},\dfrac{15}{4})[/tex].
Therefore, the coordinates of the vertex of the given parabola [tex]y=x^2+5x+10[/tex] will be [tex](\dfrac{5}{2},\dfrac{15}{4})[/tex].

A line passes through the points (0, -8) and (-9, -9). What is its equation in slope-intercept
form?
Answer:
[tex]\boxed{\sf{y=\dfrac{1}{9}x-9}}[/tex]Step-by-step explanation:
To find:
Passes through the points of (0,-8) and (-9,-9).To use:
The slope and slope-intercept form formula.Given:
The slope of a line is often indicated by the letter m.
It can be calculated by selecting any two points on the line and calculating the rate of change between them.
[tex]\underline{\text{Slope:}}[/tex]
[tex]\Longrightarrow: \sf{\dfrac{y_2-y_1}{x_2-x_1}}[/tex]
y2=(-9)y1=(-8)x2=(-9)x1=0Solve.
[tex]\Longrightarrow: \sf{\dfrac{-9-\left(-8\right)}{-9-0}=\dfrac{-1}{-9}=\boxed{\sf{\dfrac{1}{9}}}[/tex]
The slope is 1/9.
Slope-intercept form:
All points (x,y) on the line have m slope and (0,b) y-intercept that satisfy the equation.
⇒ y=mx+b, y=b+mx and y=mx+cThe m represents the slope.
The b represents the y-intercept.
The y-intercept is -8.
[tex]\Longrightarrow: \boxed{\sf{y=\dfrac{1}{9}x-8 }}[/tex]
Therefore, the correct answer is y=1/9x-8.I hope this helps, let me know if you have any questions.

Consider the equation 5 – 3(2x – 7) = 12 – 5(x – 2). Is x = 2 a solution to this
equation? Is x = 4 a solution to this equation?
Answer:
[tex]\sf x=4[/tex]
Step-by-step explanation:
[tex]\sf 5 - 3(2x - 7)=12 - 5(x - 2)[/tex]
To get rid of the parentheses, we'll apply the distributive property. Staring with the left side, multiply -3 by (2x-7).
[tex]\sf 5 - 6x+21=12 - 5(x - 2)[/tex]
5+ 21= 26
[tex]\sf 26 - 6x=12 - 5(x - 2)[/tex]
Now, let's do the same thing to the right side. Multiply -5 by (x-2) »12−5x+10, than add 12+ 10 = 22 .
[tex]\sf 26 - 6x=22 - 5x[/tex]
Combine like terms.
[tex]\sf 26 - x=22[/tex]
Subtract 26 from both sides.
[tex] \sf - x= - 4[/tex]
Multiply both sides by -1.
[tex]\sf x=4[/tex]

6. If sin e √√3 2 60° 120° 240° 420° which could not be the value of 0?
The only value of the angles that could not be the value of the θ is determined as 240⁰.
Value of sinθ
If sinθ is given as [tex]\frac{\sqrt{3} }{2}[/tex], then the value of θ is determined as follows;
sinθ = √3/2
sinθ = 0.866
θ = sin⁻¹(0.866)
θ = 60⁰
Other possible values of θWhen the angle is translated in radians, θ = π/3 = 180/3 = 60⁰
thus, θ = π/3
2(π/3) = 2(60) = 120⁰
using the following formula, we can obtain the rest;
θ = π/3 + 2πk
when k = 1;
θ = π/3 + 2π(1)
θ = 60 + 2(180)
θ = 420⁰
Thus, the only value of the angles that could not be the value of the θ is determined as 240⁰.
