What is the kinetic energy of a 1500 kg object moving at a velocity of 10 m/s?

Answers

Answer 1

It is 75000J

I checked this by plugging in the values above to the kinetic energy formula (1/2mv^2)

Answer 2

Answer:

K = 75000 Joules

Step-by-step explanation:

K = 1/2mv^2

K = 1/2(1500)(10^2)

K = 1/2(150000)

K = 75000 Joules

Jax takes a bus from Washington DC to New York City. The trip takes 5 hrs. and 47 minutes. He arrives in New York City at 1:58 pm. what time did the bus leave Washington DC?

Answers

Answer:

8:11 a.m.

Step-by-step explanation:

We need top subtract 5:47 from 1:58 pm.

Since we cannot subtract 5 from 1, we add 12 to the 1:58 hours digit.

1 + 12 = 13

1 pm is 13 hours of the day.

13:58 - 5:47 = 8:11

Answer: 8:11 a.m.

Round to the nearest hundredth:7.884

Answers

Answer:

7.88

Step-by-step explanation:

Hope this helps :D

When rounding to the nearest hundredth, the number 7.884 becomes 7.88.

To round 7.884 to the nearest hundredth, we look at the digit in the thousandth place, which is 8.

Now, If the digit to the right is less than 5, you simply drop all the digits to the right and keep the desired decimal place unchanged.

If the digit to the right is 5 or greater, you round up the desired decimal place by increasing it by one. Drop all the digits to the right.

Since 8 is greater than or equal to 5, we round up the digit in the hundredth place.

Therefore, when rounding to the nearest hundredth, the number 7.884 becomes 7.88.

What will be the new position of the given point (–2, –3) after reflection across the x-axis?
a) (2, 3)
b) (-3, -2)
c) (-2, 3)
d) (3, -2)

Answers

Answer:

(2,3)

Step-by-step explanation:

The new position of the point (–2, –3) after reflection across the x-axis is (-2,3)

How to determine the new position?

The point is given as:

(-2,-3)

The rule of reflection across the x-axis is:

(x,y) -> (x,-y)

So, we have:

(-2,-3) -> (-2,3)

Hence, the new position of the point (–2, –3) after reflection across the x-axis is (-2,3)

Given the function f(x) = 2 x + 61 - 4, for what values of x is f(x) = 6?

O x= -1, x = 11

Ox=-1, x = -11

O x= 14 = -26

O x= 26, x=-14

Answers

Answer:

[tex]x = -1[/tex] or [tex]x = -11[/tex]

Step-by-step explanation:

Given

[tex]f(x) = 2|x+6| - 4[/tex]

Required

Find x when

[tex]f(x) = 6[/tex]

Substitute 6 for f(x)

[tex]6 = 2|x+6| - 4[/tex]

Add 4 to both sides

[tex]4+6 = 2|x+6| - 4+4[/tex]

[tex]10 = 2|x+6|[/tex]

Divide both sides by 2

[tex]5 = |x + 6|[/tex]

Rewrite as:

[tex]|x + 6| = 5[/tex]

This can be split to:

[tex]x + 6 = 5[/tex] or [tex]-(x + 6)=5[/tex]

Solve for x in both cases

[tex]x = 5 - 6[/tex] or [tex]x + 6 = -5[/tex]

[tex]x = -1[/tex] or [tex]x = -6 - 5[/tex]

[tex]x = -1[/tex] or [tex]x = -11[/tex]

Answer:

i think it’s x= -1, x = -11
