What is the potential energy of a 500kg elevator that is 4.0m high from the floor?

Answers

Answer 1

Answer:

19,600 J

Step-by-step explanation:

The potential energy of a body can be found by using the formula

PE = mgh

where

m is the mass

h is the height

g is the acceleration due to gravity which is 9.8 m/s²

We have

PE = 500 × 9.8 × 4

We have the final answer as

19,600 J

Answer:

Step-by-step explanation:

5x + 2 = 4 x + 7

x = 5

Answer:

5x + 4 = 4x + 7

x = 3

Step-by-step explanation:

Let's call the mass of the unknown package "x". The equation is:

2+2 + x+x+x+x+x = x+x+x+x + 2+5

5x + 4 = 4x + 7

Now let's solve for x

5x + 4 = 4x + 7

x + 4 = 7

x = 3

Step-by-step explanation:

it increased by 20%

so the 162 is 120% of the first price

so if we multiply 162 by 100/120 we will get the first price

100/120=5/6 and 5/6*162 is 135

Step-by-step explanation:

There's no data provided in the graph. We can interpret from the options provided .

Firstly we see that the parabola opens downwards , so the coefficient of a will be negative .

Secondly we can observe the graph cuts y axis above the x axis . So the sign of constant will be positive .

All these matches with option a . Hence option A is correct .

If a 40,000g cannon ball is 35m above the Earth’s surface, how much potential energy does the cannon ball have?

Answers

Answer:

Step-by-step explanation:

Remark

You could do this by converting the distance but the much more common way is to use kg and m.

Formula

PE = m * g * h

Givens

m = 40000 grams

m = 40000 grams * 1kg/1000 grams = 40 kg

g = 9.81

h = 35 m

Solution

PE = 40 * 9.81 * 35

PE = 13734 Joules

You purchased a new car. The car had a list price of $41,070. You are paying 5.09% interest compounded monthly over a payment period of FIVE years. If you also had to pay 5.86% sales tax, a $384 vehicle registration fee, and an $89 documentation fee, what is your monthly payment?

Answers

Answer:

The monthly payment is approximately $2,356.89

Step-by-step explanation:

The list price of the car, P = $41,070

The interest rate payed, r = 5.09% compounded monthly

Therefore, the number of interest calculated per period, n = 1

The payment period, t = 5 years

The amount payed as sales tax = 5.86%

The amount paid as registration fee = $384

The amount paid as documentation fee = $89

The total amount to be paid, A = 41,070 + 41,070 × 0.0586 + 384 + 89 = 43,949.702

Therefore, the monthly payment, 'M', is given by the following formula;

[tex]M = \dfrac{P \cdot \left(\dfrac{r}{n} \right) \cdot \left(1+\dfrac{r}{n} \right)^{n \cdot t} }{\left(1+\dfrac{r}{n } \right)^{n \cdot t} - 1}[/tex]

Therefore, we get;

[tex]M = \dfrac{43,949.702\times \left(\dfrac{0.0509}{1} \right) \cdot \left(1+\dfrac{0.0509}{1} \right)^{1 \times 60} }{\left(1+\dfrac{0.0509}{1 } \right)^{1 \times 60} - 1} \approx 2,356.89[/tex]

The monthly payment, M ≈ $2,356.89.

The table shows the results of a survey of 150 students. Use the table to find the probability of a student participating in each sport.

3. Gymnastics
4. Volleyball

Answers

Answer:

See below

Step-by-step explanation:

Using the table of 150 students, we can configure probabilities.

18 students participate in tennis, so the probability of a student participating in tennis is 18/150, or 3/25 simplified.

45 students participate in football, so the probability of a student participating in football is 45/150, or 3/10 simplified.

12 students participate in gymnastics, so the probability of a student participating in gymnastics is 12/150, or 2/25 simplified.

9 students participate in volleyball, so the probability of a student participating in volleyball is 9/150, or 3/50 simplified.

Answers

Answer:

Step-by-step explanation:

We can use Hypotenuse Theorem for this:

For triangle ABC,

AC²=CB²+BA²

9²=CB²+3²

Switch the sides

-CB²=3² -9²

-CB²= 9-81

-CB²= -72

the signs cut each other

CB²=72

the square changes sides

CB=√72

CB= 8.49 cm

Now triangle CBD

We have the length of CB but not the other two whereas we have the angle

It will be sin

As we know sin= O/H

Here O is CB whereas H is CD

Put the values

sin 50= 8.49/H

H= 8.49 ÷sin 50

Calculate

H=11.1 cm

As we know H is CD so CD is 11.1 cm
