A parallelogram is a quadrilateral with two pairs of parallel sides.
A quadrilateral is a parallelogram _[blank]_.
Which answer correctly fills in the blank in the previous sentence?
A) because it has only four sides and two of them are parallel
B) if it has two pairs of parallel sides and is a polygon
C) if it has only two pairs of parallel sides
D) if and only if it has two pairs of parallel sides
Answer:
C
Step-by-step explanation:
The quadrilateral is a parallelogram if and only if it has two pairs of parallel sides option (D) is correct.
What is parallelogram?In two-dimensional geometry, it is a plane shape having four sides, in which two pairs of sides are parallel to each other and equal in length. The sum of all angles in a parallelogram is 360°.
It is given that:
A parallelogram is a quadrilateral with two pairs of parallel sides.
As we know,
The quadrilateral can be defined as the four-sided polygon in geometry having four edges and four corners.
The quadrilateral, has:
Two pairs of congruent sides.
It has one pair of opposite congruent angles.
The diagonals of a kite are perpendicular.
One diagonal is bisected.
The top and bottom angles are bisected but does not have congruent diagonals.
A quadrilateral is a parallelogram if and only if it has two pairs of parallel sides.
Thus, the quadrilateral is a parallelogram if and only if it has two pairs of parallel sides option (D) is correct.

A parabola with its vertex at (24,10) and its axis of symmetry parallel to the y-axis passes through point (4,290). Write an equation of the
parabola. Then find the value of y when x = 34.
Answer:
Not executable
Step-by-step explanation:
f(x) = a(x - h)² + k - vertex form of the equation of the parabola with vertex (h, k)
so the equation of parabola with the vertex (24, 10) is :
f(x) = a(x - 24)² + 10
the parabola's axis of symmetry parallel to the y-axis and passing through point (4,290) means: h = 4
4 ≠ 24That means you write something wrong in your question.

Find the solution to the system. Write your solution as an ordered pair (x,y) with no spaces, no solution, or infinitely many. X=2y-7 and 4x+y=71
Answer:
(15, 11).
Step-by-step explanation:
Given the system of equation;
X=2y-7 ..... 1
4x+y=71 ....2
Substitute 1 into2;
4(2y-7) + y = 71
8y - 28 + y = 71
9y - 28 = 71
9y = 71 + 28
9y = 99
y = 11
Substitute y = 11 into 1;
x = 2y - 7
x = 2(11)-7
x = 22-7
x = 15
hence the solution to the equation is (15, 11).

Rectangular coordinates (StartRoot 3 EndRoot, StartRoot 3 EndRoot) and polar coordinates (r, theta) = (StartRoot 6 EndRoot, StartFraction pi Over 4 EndFraction) both represent the same complex number z.
Which set of equations demonstrates why both sets of coordinates represent the same number?
A.) r = StartRoot 3 EndRoot + StartRoot 3 EndRoot = StartRoot 6 EndRoot and theta = inverse tangent of (1) = StartFraction pi over 4 EndFraction
B.) r = StartRoot 3 EndRoot + StartRoot 3 EndRoot = StartRoot 6 EndRoot and theta = inverse tangent of (StartRoot 3 EndRoot) = StartFraction pi over 4 EndFraction
correct one - C.) r = StartStartRoot (StartRoot 3 EndRoot) squared + (StartRoot 3 EndRoot) squared EndEndRoot = StartRoot 6 EndRoot and theta = inverse tangent of (1) = StartFraction pi Over 4 EndFraction
D.) r = StartStartRoot (StartRoot 3 EndRoot) squared + (StartRoot 3 EndRoot) squared EndEndRoot = StartRoot 6 EndRoot and theta = inverse tangent of (StartRoot 3 EndRoot) = StartFraction pi Over 4 EndFraction
Answer:
It is C. r = StartStartRoot (StartRoot 3 EndRoot) squared + (StartRoot 3 EndRoot) squared EndEndRoot = StartRoot 6 EndRoot and theta = inverse tangent of (1) = StartFraction pi Over 4 EndFraction

The rectangular coordinates (√3,√3) and polar coordinates (√6,[tex]\frac{\pi}{4}[/tex]) represent the same complex number z=x+iy because,
[tex]r=\sqrt{(\sqrt3)^2+(\sqrt3)^2}=\sqrt6[/tex] and,
[tex]\theta=\arctan(\frac{\sqrt3}{\sqrt3})=\arctan(1)=\frac{\pi}{4}[/tex]
The question is not written in an understandable manner look at the question in the below-given image.
What is polar coordinate?In terms of Cartesian coordinates, the polar coordinates r (the radial coordinate) and θ (the angular coordinate, often known as the polar angle),
x = rcosθ
(1)
y = rsinθ,
(2)
where r is the radial distance from the origin and θ is the counterclockwise angle from the x-axis. In relation to x and y,
[tex]r=\sqrt{x^2+y^2}[/tex]
(3)
[tex]\theta=\arctan(\frac{y}{x})[/tex]
How to solve it?Using the above explanation of polar coordinates we have that
[tex]r=\sqrt{(\sqrt3)^2+(\sqrt3)^2}=\sqrt6[/tex] and
[tex]\theta=\arctan(\frac{\sqrt3}{\sqrt3})=\arctan(1)=\frac{\pi}{4}[/tex]

Find the formula, in standard form y = ax2 + bx + c, for a quadratic that has roots at x = -2 and x = 7,
and has leading coefficient of 1.
y =
Answer:
[tex]y = x^2 - 5x - 14[/tex]
Step-by-step explanation:
Given
[tex]x = -2[/tex] and [tex]x = 7[/tex]
Required
Determine the quadratic equation with a leading coefficient of 1
First, we equate both expression to 0
[tex]x = -2[/tex] and [tex]x = 7[/tex] becomes
[tex]x + 2 = 0[/tex] and [tex]x - 7 = 0[/tex]
Multiply both expressions:
[tex](x + 2) * (x - 7) = 0 * 0[/tex]
[tex](x + 2) (x - 7) = 0 * 0[/tex]
Open Brackets
[tex]x^2 - 7x + 2x - 14 = 0[/tex]
[tex]x^2 - 5x - 14 = 0[/tex]
Hence, the quadratic equation is:
[tex]x^2 - 5x - 14 = 0[/tex]
or
[tex]y = x^2 - 5x - 14[/tex]
The formula, in standard form y = ax^2 + bx + c, for a quadratic that has roots at x = -2 and x = 7 is y = x² - 5x + 14
Given the standard form of quadratic equation expressed as [tex]ax^2 + bx+c =0[/tex]
If a quadratic that has roots at x = -2 and x = 7, then their factors will be x+ 2 and x - 7.
Taking the product of the factors will give:
f(x) = (x+2)(x-7)
f(x) = x² - 7x + 2x - 14
f(x) = x² - 5x + 14
Hence the formula, in standard form y = ax^2 + bx + c, for a quadratic that has roots at x = -2 and x = 7 is y = x² - 5x + 14

dan spens 3/4 of his wages on rent and 1/8 on food if he makes £240 per week how much money does he have left
Answer:
£30
Step-by-step explanation:
3/4 is the same as 6/8. [tex]\frac{6}{8}+\frac{1}{8}=\frac{7}{8}[/tex]. 7/8 of £240 is [tex]\frac{7}{8}*240[/tex] which is 210. [tex]240-210=30[/tex].
The Miller's budget $90,240 annually. If both Mr. And Mrs. Miller each work 160 hours per month, what is the average hourly wage needed to meet the budget? Round to the nearest cent.
Answer:
$23.50 per hour
Step-by-step explanation:
Since they both work this amount per month and the budget is based on their combined salary then we can combine this amount of hours for two people. Therefore, Mr. and Mrs. Miller work 320 hours each month together. There are a total of 12 months in a year meaning that ...
320 * 12 = 3,840 hours
Mr. and Mrs. Miller work a total of 3,840 hours per year. Therefore in order to meet their budget, they need to make an hourly wage of ...
90,240 / 3,840 = $23.50

The graph of y=f(x) is shown below. Which point could be used to find f(-2)
Answer:
Point B
Step-by-step explanation:
In the graph of y = f(x),
For every x-value (input value), value of the function is the y-value (output value).
For the input value x = -2,
Output value of the function will be,
y = 2
f(-2) = 2
Therefore, point B will represent the input-output values of the function.
