The slope of AB is 3.

What is the slope of a line passing through two points?

The slope of a line passing through points [tex](x_{1}, y_{1})[/tex] and [tex](x_{2}, y_{2})[/tex] is

[tex]m = \frac{y_{2}-y_{1}}{x_{2}-x_{1}}[/tex]

Given two points are [tex]A(-1, -4)[/tex] and [tex]B(2, 5)[/tex].

Therefore, the slope of a line passing through those two points is

[tex]m_{1} = \frac{5 - (-4)}{2-(-1)}[/tex]

⇒ [tex]m_{1} = \frac{9}{3}[/tex]

⇒ [tex]m_{1} = 3[/tex]

Another two points are [tex]C(3, -7)[/tex] and [tex]D(5, -1)[/tex].

[tex]m_{2} = \frac{-1 - (-7)}{5-3}[/tex]

⇒   [tex]m_{2} = \frac{6}{2}[/tex]

⇒   [tex]m_{2} = 3[/tex]

The speed of a bus weighing 2000 kg increases from 50 mls to 60 m/s in 4 s. Calculate the change in its momentum and the Force applied on it

Answers

Answer:

Momentum = 20 000 kgm/s

Force applied = 5000 N

Step-by-step explanation:

Momentum = Mass * Velocity

= 2000 kg * 10 m/s

= 20 000 kgm/s

Force = Mass * Acceleration

Acceleration = v - u / t

= 60-50/4

= 10/4

= 2.5 m/s^2

F = m*a

= 2000 * 2.5

= 5 000 N

Susanne runs a bakery. Five years ago the bakery sold 224 loaves of bread each day. Today they sell 329 loaves each day. What percent of increase in the number of loaves sold each day?

The percent of increase is %
(type a whole number or a decimal)​

Answers


224-329/224=
46.875% increase

Answer:

46.875% - (rounded answers shown below)

Step-by-step explanation:

Percent increase can be calculated by this formula:

(new-original)/original * 100.

In this problem, the 'new' value is 329 because it is the large value and is the more recent out of the two values. Therefore, the 'original' value is 224, because it is the value that is less recent than 329.

So, plugging this into the formula, (329-224)/224. This becomes 105/224, which is 0.46875. We multiply this by 100, and the value then becomes 46.875.

If you want to round this percent, it becomes 47% (whole number) or 46.9% (decimal rounded to the nearest tenth)

Using the mean concept, it is found that the mean of the distribution is of 0.64.

The mean of a probability distribution is given by the sum of each outcome multiplied by it's probability.

In this problem, the probability of each outcome is given by:

[tex]P(X = 0) = 0.513[/tex]

[tex]P(X = 1) = 0.357[/tex]

[tex]P(X = 2) = 0.109[/tex]

[tex]P(X = 3) = 0.019[/tex]

[tex]P(X = 4) = 0.002[/tex]

The, the mean is:

[tex]E(X) = 0.513(0) + 0.357(1) + 0.109(2) + 0.019(3) + 0.002(4) = 0.64[/tex]

The mean of this distribution is 0.64.

b) 10 - 20 – 45
c) -10 - 20 + 45
d) -10 – 20 - 45

Answers

Answer:

A.

Step-by-step explanation:

It's set up exactly as it is said. She starts with 10 points automatically so you would put:

10

Then it says that she lost 20 points. Losing is subtraction. You would add this to the equation:

10-20

Then it says she won 45 points. Winning is addition. You would add this to the equation:

10-20+45

This equation matches up with A. thus A. being the correct answer. If they ask for the answer, it is 35 by the way. Hope this helps!

a) 10 - 20 +45

A large cargo ship dropped anchor in the ocean. The anchor was released at a constant rate rate of speed from a height of 44 meters

Answers

Answer:

C and E

Step-by-step explanation:

The change in elevation was 44 + 20 = 64 m

the rate of fall was 64 m / 32 s = 2 m/s

The anchor reached the surface in 44 / 2 = 22 s so C is valid

E is correct as the ocean surface is origin and Up is the positive direction.

The anchor starts at 44 m above the surface and position is lower by 2 meters every second

From the question, the two correct options about the speed with which the anchor was released are:

Option COption E

How to solve for the solution

First we have to calculate the change that occurred in the elevation. Initially it was 44 meters but dropped 20 m below water.

44 + 20 = 64 meters

Next we calculate the rate with which the fall occurred

The time with which it fell was 32 seconds. = 64/32 = 2 meters pers second

44/2 = 22 hence it can be concluded that C is right.

Option E is also correct given that the water surface is above the ground and it is positive

Answer: 6

Step-by-step explanation:

4 x 6 = 24

24 x 10 = 240

So the total volume is 240, but without the units it could mean anything. 240 inches or cows, so we have to add cm, but this number could also mean any measurement of centimeters, length, area, perimeter, so we add the 3 to get

240cm3

the 3 is the symbol for cubed, meaning it's measuring the volume of a three dimensional area.
