27. Find a polar equation of the conic with focus at the pole that has the given eccentricity and equation of directrix.
e=\frac{4}{3}, r \cos \theta=-3
Answers
The polar equation will be [tex]r=\dfrac{4}{1+cos\theta}[/tex]
What is the polar equation?A polar equation is any equation that expresses the relationship between r and theta, where r is the distance between the pole (origin) and a point on a curve, and theta is the counterclockwise angle formed by a point on a curve, the pole, and the positive x-axis.
From the equation, we are told that
The Eccentricity: e = 1
The Directrix is y = 4
Generally, the polar equation for e = 1 and y = + c is mathematically represented as
[tex]r =\dfrac{e\times c}{1+ecos\theta}[/tex]
[tex]r =\dfrac{1\times 4}{1+1\times cos\theta}[/tex]
[tex]r=\dfrac{4}{1+cos\theta}[/tex]
Therefore the polar equation will be [tex]r=\dfrac{4}{1+cos\theta}[/tex]

Enter the answer in the box.
Answers
Answer:
7
Step-by-step explanation:
The interquartile range of the data set is 7.
Step-by-step explanation:
The given set of data is
(18, 17, 10, 25, 20, 20, 30, 18, 18, 30, 25)
Arrange the data in ascending order.
10, 17, 18, 18, 18, 20, 20, 25, 25, 30, 30
Divide the data in two equal parts.
(10, 17, 18, 18, 18), 20, (20, 25, 25, 30, 30)
Divide each parenthesis in 2 equal parts.
(10, 17), 18, (18, 18), 20, (20, 25), 25, (30, 30)
Now we can say that,
Q1 = 18, Median = 20, Q3 = 25
Interquartile rage of a data is
I.Q.R. Q3 Q₁
I.Q.R.25-18=7
Therefore the interquartile range of the data set is 7.
( 50 points ) A train travels at an average speed of 80 km/h. How long will it take the train to travel 320 km?
Answers
Answer:
4 hours
Explanation:
[tex]\sf time = \dfrac{distance}{speed}[/tex]
Here the units are same for both, so no need of conversion.
Solve:
time taken = distance/speed
time taken = 320/80
time taken = 4 hours
Answer:
4 hours
Step-by-step explanation:
[tex]\text{Speed} =\frac{\text{distance} }{\text{time} }[/tex]
Then
[tex]\text{time} =\frac{\text{distance} }{\text{speed} }[/tex]
Then
[tex]\text{time} =\frac{\text{320} }{\text{80} } =4[/tex]

Below is the graph of y equation y=-|x-2|+3. Use this graph to find all values of x given each statement. a) -|x-2|+3>0 b) -|x-2|+3<0 c) -|x-2|+3=0
Answers
Answer:
The answer is C) - |x - 2| + 3 = 0
Step-by-step explanation:
a) - |x - 2| + 3 > 0
The greater than means something above the graph.
b) - |x - 2| + 3 < 0
The less than means something below the graph.
c) - |x - 2| + 3 = 0
The zero doesn't do anything.
y = - a |x - h| + k = 0
(h,k) is the origin.
h is shift left/right, h = 2 so shift right 2.
k is shift up/down, k = 3 so shift up 3.
The a, affects the y-values which cause the graph to reflect across the x-axis.
What is the value of x when 5x=6.5?
Answers
Answer:
x= 1.3
Step-by-step explanation:
First, separate x, by dividing both sides by 5
[tex]5 \div 5x = 6.5 \div 5[/tex]
which equals
x= 1.3
Answer: 1.3
Step-By-Step explanation:
5x=6.5
5x/5=6.5/5
x=1.3
We have to get X alone but to do that we had to cancel 5 and bring to the other side. So we did the opposite from what it said to do so instead and 5*x we divided. But we cannot just do that on one side so we had to do it on the other which ended us of with x=1.3

PLEASE HELP QUICK. (WIlL GIVE BRAINLIST) Erina runs 200 meters each day during the first week of her training. She plans to increase the distance she runs each week. Erina's training goal is to run 150% of the distance she ran each day in the previous week. She will run the same distance each day in a week. There are approximately 27.34 yards in 25 meters. If Erina meets her goal, how many yards will Erina run each day in the third week of her training? Round the answer to the nearest hundredth. Enter the answer in the box _____ yards
Answers
During the first week of her training, she runs 200 meters. On the second week, she plans to run 50% more.
Now, how do you calculate this?
To increase 200 meters by 50%, multiply by 1.5
The second week she pans to run 450 meters.
Since there are only 3 weeks, do it again!
The thrid week, she plans to run 675 meters.
Since she runs the same ammount each day of the week, the calculation is simple.
7(200) + 7(450) + 7(675)
In these three weeks, she runs 9275 meters.
OR, she runs 10143.26 yards.

Answer:
Angle x = 72
Step-by-step explanation:
Angle AHI = Angle HIK = 63
(This is because the two angles are corresponding angles, HI//JK)
Angle x = 180 - 63 - 45
= 72
A triangle makes 180 degrees total no matter what so if we have two angle measures we can add them and subtract from 180. 63 + 45 = 108. 180-108= 72 degrees :)

Answer: The answer to 2, 6, 12, 16 is 9 and the answer to 5, 6, 12, 13 is 9
Step-by-step explanation: The mean of a set of numbers is another term for average. You add all of the numbers up like for example in the second set of numbers, 16+12+6+2 is equal to 36 and you then divide that sum by the amount of numbers you added which in this case is 4 so you get 36/4 which is equal to 9.
Mean of 2, 6, 12, 16 = (2 + 6 + 12 + 16) ÷ 4 = 36 ÷ 4 = 9
Mean of 5, 6, 12, 13 = (5 + 6 + 12 + 13) ÷ 4 = 36 ÷ 4 = 9

Step-by-step explanation:
The sample space is the range of values a random variable may have. In this process, the random variable will have the value of one of the letters shown. That is, it will be one of {A, B, F, K, S}.
The sample space is A, B, F, K, S.

5. SereN and Visala had a combined total of $180. SereN then gave Visala $20, and then Visala gave SereN a quarter of the money Visala had. After this, they each had the same amount. How much money did SereN start with?
Answers
The amount of money seren had will be $132.
what is a linear equation?
It is defined as the linear relation between two variables, if we plot the graph of the linear equation we will get a straight line.
Given that:-
Seren and Visala had a combined total of $180Seren then gave Visala $20, and then Visala gave Seren a quarter of the money Visala had. After this, they each had the same amount.
The solution will be done by making an equation:-
According to the first condition:-
S + V = $180
Now from the second condition:-
S - 20 + { ( v + 20 ) / 4 ) } = 180
Since S = v then:-
S - 20 + { ( S + 20 ) / 4 ) } = 180
S = $132
Therefore the amount of money seren had will be $132.
