Step-by-step explanation:
Quadrilateral ABCD is a parallelogram if both pairs of opposite sides are congruent show that quadrilateral ABCD is a parallelogram by finding the length of the opposite side pairs
Answer:
D. 21, 14
Step-by-step explanation:
As the question said, a parallelogram is formed when both pairs of opposite sides are congruent. That means that 21 and 3y are equal, as are y + 7 and 2y.
21 = 3y
/3 /3
7 = y
y + 7 = 2y
-2y -2y
-y + 7 = 0
- 7 - 7
-y = -7
* -1 * -1
y = 7
In both instances, y = 7. Now let's substitute that.
21 = 3(7)
21 = 21 is true.
7 + 7 = 2(7)
14 = 14 is true.
With that, the lengths of the opposites sides are 21 & 14, which is D.
PLZ ANSWER THIS I CANT FIGURE OUT THE SECOND ONE
(INSTANTANEOUS ROC)
I will give you brainiest if you answer it right
Answer:
Step-by-step explanation:
The first one is actually 0 I think. The instantaneous ROC at x=1 should also be 0. The last one should be correct.
Basically, the ROC for the first one is 0 because the y value at the start and end of the interval is the same, so the change is the same. However, for the instantaneous ROC at x = 0, you look at the graph and realize that if you find the derivative at that point, it is 0.

A circle is graphed on a coordinate grid and then reflected across the y axis. if the center of the original circle was located at (x,y), which ordered pair represents the center of the new circle after the transformation?
Answer:
(-x,y)
Step-by-step explanation:
If it's positive and you flip it accross the y-axis, the x- coordinates become negative.

Answer:
x=60°,120°
Step-by-step explanation:
4sinx=3cosecx
4sinx-3cosecx=0
4sinx-3/sinx=0
4sin²x-3=0
sin²x=3/4
sinx=√(3/4)
sinx=√3/2=sin60°,sin(180-60)
Answer:
sin(180-60) is the correct answer Hope it helps you have a great day keep smiling be happy stay safe
Find the values of the measures shown when each value in the data set increases by 25. Mean: 109 Median: 104 Mode: 96 Range: 45 Standard deviation: 3.6
Answer:
The new values are as follows:
Mean: 134
Median: 129
Mode: 121
Range=45
Standard Deviation=3.6
Step-by-step explanation:
When a k real number is added to all the elements of the dataset, the new measures of center (mean, median, and mode) are simply found by adding the value k to the previous values. Thus
[tex]Mean_{new}=Mean_{old}+k[/tex]
Here [tex]Mean_{old}[/tex] is 109 and k is 25 thus
[tex]Mean_{new}=Mean_{old}+k\\Mean_{new}=109+25\\Mean_{new}=134[/tex]
Similarly
[tex]Median_{new}=Median_{old}+k[/tex]
Here [tex]Median_{old}[/tex] is 104 and k is 25 thus
[tex]Median_{new}=Median_{old}+k\\Median_{new}=104+25\\Median_{new}=129[/tex]
Also
[tex]Mode_{new}=Mode_{old}+k[/tex]
Here [tex]Mode_{old}[/tex] is 96 and k is 25 thus
[tex]Mode_{new}=Mode_{old}+k\\Mode_{new}=96+25\\Mode_{new}=121[/tex]
When a k real number is added to all the elements of the dataset, the new measures of variation (range and standard deviation) remain the same thus.
[tex]Range_{new}=Range_{old}\\Range_{new}=45[/tex]
Similarly
[tex]Standard\ Deviation_{new}=Standard\ Deviation_{old}\\Standard\ Deviation_{new}=3.6[/tex]
So the new values of mean, median, mode, range, and standard deviation are 134, 129, 121, 45, and 3.6 respectively.

What is the coefficient of x4 y3 term in the expansion of ( x-2y )7?
The coefficient of x⁴y³ term in the expansion of (x - 2y)⁷ is 280.
What is expression?Mathematical expressions consist of at least two numbers or variables, at least one arithmetic operation, and a statement.
Given expression:
(x - 2y)⁷
Expand this as given below,
(x - 2y)³ × [(x - 2y)²]²
(x³ + 6x²y + 12xy² + 8y³) × [(x² + 4y² - 4xy)]²
Solve the above expression to get,
x⁷ + 14x⁶ + 84x⁵y² + 280x⁴y³ + 560x³y⁴ + 672x²y⁵ + 448xy⁶ + 128y⁷
Here, the coefficient of the x⁴y³ is 280,

7. Mahmoud runs to a marker and back in 15 minutes. His speed on
the way to the marker is 5 m/s and his speed on the way back is
4 m/s. Find the distance to the marker.
Answer:
2000 meters
Step-by-step explanation:
From the above question
Total time = 15 minutes
Converting minutes to seconds
1 minute = 60 sec
15 minutes = x
Cross Multiply
x = 60 × 15 = 900 seconds
Hence, 900 seconds = Total time
Total time = Time to the marker + Time from the marker
From the question, we are given the Speed to the marker = 5 m/s
Speed from the marker = 4 m/s
Time = Distance/speed
Let the distance be represented by x
Hence:
x/4 + x/5 =900
Multiply all through equation by Lowest Common Denominator = 20
5x + 4x= 900×20
9x = 900 ×20
Divide both sides by 9
9x/9 = 900 × 20/9
x = 2000 meters
Therefore, the total distance to the marker = 2000 meters

Which of the following is the equation of a line that has a slope of -2 and passes through the
point (1,6)?
A.y=x+6
B.y=-2x+8
C.y=-2x+4
D.y=1/2x+4
Answer:
B. y = -2x + 8
Step-by-step explanation:
So the slope is the number that comes before the x, and if the slope is -2, that means the number before is -2, and it is.
And to know if it goes through (1, 6), put those numbers into the equation and see if they match up (x is the y-intercept)
6 = -2(1) + x
6 = -2 + x
x = 8

Find the surface of this triangular prism please
Answer:
270cm²
Step-by-step explanation:
The formula is given as
S = bh × l (s1 + s2 + h)
l = 7cm
h = 5cm
s1 = 12 cm
s2 = 13cm
b = 12 cm
Surface Area = 12 cm × 5 cm × 7 cm(12 cm+ 13 cm+ 5cm)
= 60cm² × 7 cm(30 cm)
= 60cm² + 210 cm²
= 270 cm²

Factor 48-8x to identify the equivalent expressions
Choose two answers.
Answer:
8(6 - x)
Step-by-step explanation:
I'm not exactly sure why the question asks for two answers.
We need to find the highest common factor that goes into both 48 and -8x.
That common factor is 8.
48 / 8 = 6
-8x / 8 = -x
Now, we factorise.
