Answer: the maximum amount of time the skier is in the air would be the time to "fall" the 50 meters.

$distance = 1/2 a t^2$

$50 = 1/2 (9.8) t^2$

$t= 3.2 seconds$

Which equation results from taking the square root of both sides of (x – 9)2 = 81?

Answers

In the question "Which equation results from taking the square root of both sides of (x – 9)2 = 81?" The correct answer is x - 9 = +/- 9. Taking the square root of both sides of the equation (x - 9)^2 = 81 will give: sqrt(x - 9)^2 = sqrt(81) x - 9 = +/- 9 Solving the equation results in two equation: x - 9 = 9 and x - 9 = -9 x = 9 + 9 and x = -9 + 9 x = 18 and x = 0

According to the Fundamental Theorem of Algebra, how many roots exist for the polynomial function?f(x) = 4x5 – 3x
1 root
2 roots
4 roots
5 roots

Answers

Answer:

Option 4 is correct that is according to fundamental theroem of algebra the given polynomial function will have 5 roots

Step-by-step explanation:

The fundamental theorem of algebra says that the polynomial will have the number of roots equal to the degree of the polynomial.

Degree is the highest power of polynomial.

Here we have given the polynomial $4x^5-3x$ where degree is 5.

Hence, the given polynomial will have 5 roots.

Therefore, option 4 is correct that is 5 roots

To draw the model to represent 3/4 divided by 3/12.

What is arithmetic?

In mathematics, it deals with numbers of operations according to the statements.

Model hs been attached below for the given problem of division,
= 3 * 4 / 3 * 12
For a rectangle space, drawing 4 column and 12 raws,
Now for 3 / 4 3 of the 4 column to be filled by red, for 3 / 12 every 3 cells in the row have been filled by red.
Calculating number of cells in 3 / 4 = 36
calculating number of cells in 3 / 12 = 12
Now ratio of the cells = 36 / 12 = 3

Thus, the required model is attached in the image and the division of 3/4 by 3 /12 is 3.

#SPJ2

The answer you are looking for is 1/3.

First, you must look at the denominators of each fraction, to see if you can simply divide straight across. In this case, you cannot, which means you must multiply by the reciprocal or "flipped" number. Generally when you multiply by the reciprocal, you flip the number with the smaller denominator to multiply.

So, you have 4/3 * 3/12. You then multiply straight across (4 * 3)/(3 * 12), to get an answer of 12/36, which simplified (divided by 3/3) gives you a final answer of 1/3.

I hope this helps!

Answers

Answer:

$BE=12 units$

Step-by-step explanation:

$We\ know\ that,\nIn\ a\ rectangle\ all\ diagonals\ are\ equal\ and\ bisect\ each\ other.\nHence,\nIn\ Rectangle\ ABCD,\nAE=EC\nHence,\nSubstituting\ the\ values\ we\ get:\nx+4=3x-12\nHence,\n-2x=-16\nx=(-16)/(-2)=8\nNow,\nWe\ also\ know\ that,\n AC=DB\nHence,\n(AC)/(2)=(DB)/(2) \nHence,\nDE=EB=AE=EC\nHence,\nSince\ AE=BE,\nBE=x+4\nWe\ already\ know\ that\ x=8.\nHence, BE=8+4=12$
