Answer:

What is acceleration?

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.”

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

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:

Angle L would still be 45 degrees because the size of the triangle did not change when it was moved

Step-by-step explanation:

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]

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.

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.

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.

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.

Answer: A way citizens can directly influence the public policy is by following it or not. If there is a policy that no one agrees with, they will not follow it and show that the policy is wrong. When this is done, the policy will go away. That is how citizens can directly change this.

Answer:

$36

Step-by-step explanation:

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

Note: I used a scientific calculator for some calculations.
