Answer:
6 units
Step-by-step explanation:
Use the distance formula, [tex]\sqrt{(x_{2}-x_{1})^{2}+(y_{2}-y_{1})^{2}}[/tex].
Plug the x and y values from the given points into the distance formula:
[tex]\sqrt{([-4]-2)^{2}+(5-5)^{2}}[/tex].
Solve the square root:
[tex]\sqrt{36}[/tex] = [tex]\sqrt{6^{2}}[/tex] = [tex]6[/tex]

4sinx=3cosecx(0<=X<=180°)
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
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

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.

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
At a football game, a vender sold a combined total of 181 sodas and hot dogs. The number of hot dogs sold was 51 less than the number of sodas sold. Find the
number of sodas sold and the number of hot dogs sold.
Answer: Number of hot dogs sold = 65
number of soda sold = 116.
Step-by-step explanation:
Let the number of hot dogs sold be represented by x.
Since the number of hot dogs sold was 51 less than the number of sodas sold, then the number of soda sold will be: = x + 51
Since the addition of both hot dogs and soda equals 181, we can form this into an equation which will be:
= x + (x + 51) = 181
x + x + 51 = 181
2x + 51 = 181
2x = 181 - 51
2x = 130
x = 130/2
x = 65
Number of hot dogs sold = 65
Since number of soda sold equals:
= x + 51
= 65 + 51
= 116
Therefore, number of soda sold is 116.
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 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.

Martha rolls a 6 sided number cube two times.
What is the probability that she will roll a prime number both times.
Answer:
25% chance
Step-by-step explanation:
There are 3 prime numbers on a 6-sided die so that means there is a 1/2 chance you roll a prime number. In order to calculate the probability of 2 or more events you multiply their probability which would be
1/2 * 1/2 = 1/4
So the chance of rolling a prime number on both rolls is a 1/4 chance or a 25% chance
The probability that she will roll a prime number both times is 0.25.
What is the probability?The Probability in mathematics is the possibility of an event in time. In simple words, how many times that incident is happening in any given time interval.
Given:
Martha rolls a 6 sided number cube two times.
And the prime numbers in the cubes are {2, 3, 5}.
The probability that she will roll a prime number both times,
= 3/6 x 3/6
= 1/2 x 1/2
= 1/4
= 0.25
Therefore, 0.25 is the probability.
