Given:
One of the angles of a parallelogram , ∠A = 40°
To find out:
Find the rest of the angles ( ∠B, ∠C, ∠D ) ?
Solution:
We know that,
∠A + ∠B = 180° [ co - interior angles]
⇒ 40° + ∠B = 180°
⇒ ∠B = 180° - 40°
⇒ ∠B = 140°
∠B = ∠D = 140° [ Opposite angles of a parallelogram ]
Also, ∠A = ∠C = 40° [ Opposite angles of a parallelogram ]

can anyone rewrite the quadratic function in standard form?
Answer:
y = -2(x-2) (x+8)
Step-by-step explanation:
got you bro
Answer:
y = -2x² -12x + 32.
Step-by-step explanation:
Recall that a quadratic equation in standard form is:
y = ax² + bx + c.
To rewrite the equation in standard form, you will need to FOIL and distribute the -2. This can be done by:
y = -2(x-2)(x+8)
FOIL the factored part of the equation. Ignore the '-2' for now.
y = -2 (x² +6x -16)
Now, multiply the '-2' with all of the terms:
y = -2x² -12x + 32.
This is your equation in standard form!

Write the equation of a circle centered at the
point P(-4,-6) and passing through the point
R(2,2).
Answer:
[tex](x+4)^2+(y+6)^2=100[/tex]
Step-by-step explanation:
Given a circle centred at the point P(-4,-6) and passing through the point
R(2,2).
To find its equation, we follow these steps.
Step 1: Determine its radius, r using the distance formula
For point P(-4,-6) and R(2,2)
[tex]\text{Distance Formula=}\sqrt{(x_2-x_1)^2+(y_2-y_1)^2} \\\text{Radius=}\sqrt{(2-(-4))^2+(2-(-6))^2} \\=\sqrt{(2+4))^2+(2+6)^2}\\=\sqrt{6^2+8^2}\\=\sqrt{100}\\Radius=10[/tex]
Step 2: Determine the equation
The general form of the equation of a circle passing through point (h,k) with a radius of r is given as: [tex](x-h)^2+(y-k)^2=r^2[/tex]
Centre,(h,k)=P(-4,-6)
r=10
Therefore, the equation of the circle is:
[tex](x-(-4))^2+(y-(-6))^2=10^2\\\\(x+4)^2+(y+6)^2=100[/tex]

Which are not changed after a rotation? Check all that apply
angle measures
orientation
size
shape
position of center of rotation
Answer:
Angle measures, size, shape, position of center of rotation.
Step-by-step explanation:
Rotation is a rigid motion, meaning the angle measures, size, and shape are preserved. Also, since we are rotating around the center, the center would stay the same. So the answer is angle measures, size, shape, position of center of rotation.
When a shape is rotated, it must be rotated through a center.
Angle measures , the size , the shape , and the position of center of rotation do not change after rotation
Rotation is a rigid transformation.
This means that, rotation does not change the angle measure, the side lengths and the shape of the shape that is being rotated.
Except the center of rotation is changed to perform another rotation, the rotation does not change the center of rotation.
Hence, all except orientation remain unchanged after a rotation.

find points of discontinuity y=x^2+5x+6/x^2-16
Answer:
x=4 and x=-4
Step-by-step explanation:
We assume you intend ...
y = (x^2 +5x +6)/(x^2 -16)
There will generally be points of discontinuity where the denominator is zero. Sometimes a denominator factor will be cancelled by a numerator factor, but the "hole" remains and there is still a discontinuity there.
Here, the denominator factors as the difference of squares:
x^2 -16 = (x -4)(x +4)
There will be discontinuities where these factors are zero, at x=4 and x=-4.
Given that sin 60 = root3/2
Find the exact value of sin 240
Answer:
[tex]sin 240^\circ = - \dfrac{\sqrt{3}}{2}[/tex]
Step-by-step explanation:
We are given that:
[tex]sin 60^\circ = \dfrac{\sqrt{3}}{2}[/tex]
We need to find
[tex]sin 240^\circ = ?[/tex]
240 is greater than 180 and lesser than 270
OR
[tex]180^\circ<240^\circ<270^\circ[/tex]
So, Angle [tex]240 ^\circ[/tex] lies in the 3rd quadrant and it is well known that value of sine in 3rd quadrant is negative.
Using the property :
[tex]sin(\pi + \theta) = -sin\theta[/tex] or
[tex]sin(180^\circ + \theta) = -sin\theta[/tex]
Here, [tex]\theta\ is\ 60^\circ[/tex].
[tex]sin 240^\circ =sin(180^\circ + 60^\circ) = -sin60^\circ\\\Rightarrow -\dfrac{\sqrt{3}}{2}[/tex]
Hence, the value
[tex]sin 240^\circ = - \dfrac{\sqrt{3}}{2}[/tex]

Answer:
8 large candles
Step-by-step explanation:
If all the candles were large candles,
Amount received
= 20( $27.98)
= $559.60
Difference in amount received
= $559.60 -$355.60
= $204
Difference in the cost of a small candle to a large candle
= $27.98 -$10.98
= $17
Number of small candles
= $204 ÷$17
= 12
Thus, number of large candles
= 20 -12
= 8
Let's check!
Amount received
= 8( $27.98) +12( $10.98)
= $355.60 ✓
