triangle. l m is the image of triangle lmn after a translation. How are the side lengths and angle measures of the triangles related? Explain
Answer:
Angle L would still be 45 degrees because the size of the triangle did not change when it was moved
Step-by-step explanation:
Put the equation 169x^2+25y^2-4225=0 in standard form and sketch the ellipse including the foci in your sketch
Answer:
The standard form of the ellipse is [tex]\frac{x^{2}}{25} +\frac{y^{2}}{169} = 1[/tex]. Coordinates of the foci are [tex]F_{1} (x,y) = (0,-c)[/tex] and [tex]F_{2}(x,y) = (0,c)[/tex], respectively.
Step-by-step explanation:
The equation of a ellipse centered in the origin in standard form is defined by following formula:
[tex]\frac{x^{2}}{a^{2}}+\frac{y^{2}}{b^{2}} = 1[/tex] (1)
Where [tex]a, b[/tex] are the coefficients of the ellipse.
Now we proceed to transform the equation of the ellipse in general form into standard form by algebraic means:
[tex]169\cdot x^{2}+25\cdot y^{2}-4225 = 0[/tex]
[tex]169\cdot x^{2}+25\cdot y^{2} = 4225[/tex]
[tex]\frac{x^{2}}{25} +\frac{y^{2}}{169} = 1[/tex]
Since [tex]b > a[/tex], then major axis of the ellipse is located in y-axis. The distance between center and focus ([tex]c[/tex]) is calculated by following Pythagorean identity:
[tex]c =\sqrt{b^{2}-a^{2}}[/tex] (2)
[tex]c = 12[/tex]
The location of the foci are represented by [tex]F_{1} (x,y) = (0,-c)[/tex] and [tex]F_{2}(x,y) = (0,c)[/tex]. If we know that [tex]c = 12[/tex], then the location of the foci are, respectively:
[tex]F_{1}(x,y) = (0,-12)[/tex], [tex]F_{2}(x,y) = (0,12)[/tex]

Answer:
16 and 18
Step-by-step explanation:
1=5 80/5=16
1=9 2x9=18
Answer:
16 centimeters and 18 feet
Step-by-step explanation:
The scale for the fist one is 1 centimeter and that gives you 5 meters. So set up a proportion to see what 80 meters would get you. 1cm/5m=Xcm/80m. You would divide 80 by 5 to find the amount of centimeters which would be 16.
For the next one it is similar. Set up the proportion 1in/9ft=2in/Xft. You would end up with x=9times2 which would give you 18 ft.

So, BC=3(11)-8=33-8=25
M- Determine whether or not the procedure described below results in a binomial distribution. If it is not binomial, identify at least one requirement that is not satisfied.Six hundred different voters in a region with two major political parties, A and B, are randomly selected from the population of 5500 registered voters. Each is asked if he or she is a member of political party
A. Yes, the result is a binomial probability distribution.B. No, the trials are not independent and the sample is more than 5% of the population.C. No, there are more than two possible outcomes.D. No, the number of trials is not fixed.E. No, the probability of success is not the same in all trials
Answer:
A. Yes, the result is a binomial probability distribution.
Step-by-step explanation:
The experiment above depicts a binomial probability distribution because the 4 required conditions are met :
1.) The distribution is independent as the possible outcome of each trial is the same.
2.) There are two possible categories and the result of each trial is one of two outcomes : Yes or No
3.) The number of observation is fixed at sample size of 5500
4.) The probability of success and failure of each trial is the same for all trials in the sample.
Hence, we can conclude that the experiment depicts a binomial probability distribution.

Imagine you are playing golf, and you’ve just set up the golf ball on the tee. You test your grip, take a few practice swings, and peer into the distance at the flag pole marking the first hole for the course. Your wise golf ball guru (who happens to also teach physics) tells you to “Be the ball, young grasshopper.” So you close your eyes and picture the distance the ball must travel. “Yes, young earthworm”, your sensei says, “that distance you see is the displacement you must achieve, displacement is the change in position from one place to another.”

Which of the following is equal to 7?
I. lim hx)

II.
lim h(x)
x->2+
III.
lim h(x)
x->2
Sorry to disappoint, but none of these answers are correct. All three limits are equal to 7.
Compute the one-sided limits:
[tex]\displaystyle\lim_{x\to2^-}h(x)=\lim_{x\to2}(x^2-x+5)=2^2-2+5=7[/tex]
[tex]\displaystyle\lim_{x\to2^+}h(x)=\lim_{x\to2}(x^3-1)=2^3-1=7[/tex]
Both the one-sided limits agree, so the two-sided limit has the same value,
[tex]\displaystyle\lim_{x\to2}h(x)=7[/tex]
If we divide Rs 20 between Jatin and Arnav in the ratio 3 : 2, how much will each of
them get?
Answer:
$12
$8
Step-by-step explanation:
Amount Jatin received = (ratio of Jatin's share / sum of ratios) x amount shared
sum of ratios = 3 + 2 = 5
(3/5) x 20 = $12
Amount Arnav received = (ratio of Arnav's share / sum of ratios) x amount shared
(2/5) x 20 = $8
or
$20 - $12 = $8

Mark as brainlist mate
because making my answer as brainlist you would not lose anything।।।।।।।।।।A store buys a jackets for $20.00 and sells it for 80% more than that what is the selling price of the jacket
Answer:
$36
Step-by-step explanation:
in the beginning $20 is %100 so divide 20 by 100 .you'll get .2 but to make this simple you'll want %10 so multiply .2 times 10 and you get 2 .now that 2 is %10 and you want %80 you multiply 2 8 times (or add it 8 times) because %10 times 8 = %80 so 2 times 8 = 16 .now that you have the %80 you want to add it to the %100 because they sold it for %80 then the price they bought if for (you get %180) . then you add the $20 to the $16 because that is what each percent equals (you get $36)
Answer:
$36
Step-by-step explanation:
What we know: The jacket is marked up by 80% of the jacket. The store is now selling the jacket for 180% of what they bought it for.
Set up problem: x 180%
___ = ____
$20 100%
What do the numbers mean when set up like this(referring to problem set up): We know that $20 is the original price of the jacket. So $20 is 100% of the jacket(if that makes sense). Markup is 80% because "sells it for 80% more" . So it goes on top.
Solving the Problem#1: 180 x 20 = 3600
Solving the Problem#2: 3600/1000= $36
Checking My Math: What is 80% of $20. Let's divide $20 into 4 parts.
$4 + $4 + $4 + $4 + $4 =20
$4 is 20% of 20
$8 is 40% of 20
$12 is 60% of 20
$16 is 80% of 20
$20 is 100% of 20
Final Answer: $36 is the selling price of the jacket

Which expression is equivalently to x^2 + 2x + 2?
Answer:
(X-1+I)(x-1-I)
Step-by-step explanation:
Expression (x + 1 - i)(x + 1 + i) is equivalent to x² + 2x +2.
Option (B) is correct option.
What is an algebraic expression?Variables, integers, and a variety of mathematical procedures make up an algebraic expression.
To find the expression equivalent to x² + 2x +2,
Solve with the help of options.
(A)
(x - 1 + i)(x - 1 - i)
Solve by using formula (a + b)(a - b) = a² - b²
(x - 1 + i)(x - 1 - i) = (x -1)² - i² = x² + 1 - 2x +1 = x² - 2x + 2
(B)
(x + 1 - i)(x + 1 - i)
Solve by using formula (a + b)(a - b) = a² - b²
(x + 1 - i)(x + 1 + i) = (x + 1)² - i² = x² + 1 + 2x +1 = x² + 2x + 2
Expression in option (B) is equivalent to x² + 2x + 2.
