Daredevil Danny was cliff jumping. He jumped off a cliff that was 14.2 meters above the surface of the
water. At the end of his jump, Danny was 2.3 meters below the surface of the water.
The following equation describes this situation
14.2 + (-16,5) = -23
What does -16.5 tell us?

Answers

Answer 1

Answer:

AnSwEr Is C

Step-by-step explanation:

in khAN

Answer 2

The value  -16.5 tells us the displacement between his current position and his initial position.

What is displacement?

Displacement is defined as the minimum distance between two points. It is a vector quantity and needs direction with magnitude.

It is given that

Initial position =14.2 m

Final position=-2.3 m

14.2+(16.5)=-2.3

To understand this, we need to first calculate the displacement between his initial and final position

Displacement = Final pposition - Initial position

Displacement= -2.3-14.2

Displacement =-16.5 m

So: -16.5m is the total displacement from the start position (i.e. off the cliff) and current position (beneath the water surface)

I know someone else responded but theres an easier way to solve this without multiplying anything.
Neg*neg=pos
1. Has two neg and two negs make a pos
2. Has 4 neg which will also make pos
3. Has 3 neg. The first 2 will cancel out and make a pos but the last one will make the answer neg
4. Would just be 0 because its multiplying 0 but without it it would be neg.

Answer:

D. None of the above.

Step-by-step explanation:

To evaluate the expression when x = 6, we substitute 6 for x in the expression:

2 - 3(x - 5)

= 2 - 3(6 - 5)

= 2 - 3(1)

= 2 - 3

= -1

Therefore, the value of the expression when x = 6 is -1.

So, the answer is D. None of the above.

Answer: none of the above

Step-by-step explanation:

When x = 6 We substitute 6 for x in the expression:

2 - 3(x - 5)

2 - 3(6 - 5)

2 - 3(1)

2 - 3

= -1

X/3 - 2 + X/2 + 6 =3

5X/6 + 4 = 3

5X/6 = 3 - 4

5X/6 = - 1

5X = - 1 times 6

5X = - 6

X = - 6/5

And in decimal form: - 1.2

Answer:

x=−6/5

Step-by-step explanation:

\(\frac{x}{3} - 2 + \frac{x}{2} + 6 = 3\\\)

Simplify both sides of the equation:

\(\frac{x}{3} - 2 + \frac{x}{2} + 6 = 3\)

\(\frac{1}{3} x + -2 + \frac{1}{2} x + 6 = 3\)

\(( 1/3x + 1/2x ) + ( −2+6 ) = 3\)   (Combine Like Terms)

\(5/6 x + 4 = 3\)

Subtract 4 from both sides:

\(5/6x + 4−4= 3−4\)

\(5/6x = −1\)

Multiply both sides by 6/5:

\((6/5) * (5/6x) = (6/5) * (−1)\)

There are 12 students who has 2 or fewer siblings.

There are only 4 students who has 3 siblings.

There are only 2 students who has no siblings or 6 siblings.

You are given a triangle with side lengths of 6, 9, and 12. Is the triangle a right triangle? How do you know?

Answers

Answer:

No, it's not

Step-by-step explanation:

You choose the longest side which is 12 and apply the theory of phitagors

The longest side which is the hypotenuse in a right triangle = square root the square sum for each side

So to be a right triangle it should be

\( \sqrt{ {9}^{2} + {6}^{2} } = 10.8 \: \: that \: doesnt \: equal \: 12\)

So it's not a right triangle.

Look at the famous right triangle whose side are 5(hypotenuse), 4, 3

\( \sqrt{ {4}^{2} + {3}^{2} } = 5\)

So it's a right triangle

I’m happy to help!
Right triangle lengths can be checked by the Pythagorean theorem.
This states that a^2+b^2=c^2
a and b are the shorter side lengths, and they form the right angle. c is the hypotenuse, and is the longest length.
Input the values to check if the equation checks out:
6^2+9^2=12^2
36+81=144
117≠144
No, it is not a right triangle. Hope this helps!

What is the solution to this system?

What is the solution to this system?

Answers

Answer: There is no solution

Step-by-step explanation:

The system of a systems of equations on a graph is the coordinate where the 2 lines intersect, or come together. In this picture, the 2 lines don't intersect at a point, so there is no solution. Here are some rules for systems of equations on a graph:

How to know if it has 'infinite' solutions: If it has infinite solutions, the 2 lines share the same points. In other words, they are basically just on top of each other, or in the exact same spot.

How to know if there are 'no solutions': The 2 lines never come together (intersect). This is true in this graph because they are always apart.

How to know if there is 'one solutioin': The 2 lines cross each other, come together, or intersect (all the same meaning), at 1 point .

A: The slope is 2.1. This means that each kilometer costs $2.10.
B: The slope is 5. This means that each kilometer costs $5.
C: The y-intercept is 2.1. This means that the initial fee is $2.10.
D: The y-intercept is 5. This means that the ride lasts 5. kilometers.

Which one is right and why?

Answers

THIS MIGHT NOT BE WHAT YOU ARE LOOKING FOR AND MIGHT NOT BE CORRECT! READ FIRST!

The answer is A. The slope of the line is rise/run = 4/2 = 2.1. This means that each kilometer costs $2.10. The y-intercept is 2.1, which means that the initial fee is $2.10. So the correct statement is: The slope is 2.1. This means that each kilometer costs $2.10.

The other statements are incorrect. The slope is not 5, so each kilometer does not cost $5. The y-intercept is not 5, so the ride does not last 5 kilometers. The y-intercept is the value of the function when the input is 0, which in this case is the initial fee of $2.10.
