Answer:
the magnitude of the vector is given by the √(px^2+py^2) so the value is 5.65
The magnitude of the given vector (4, -4) in the simplified form will be 5.65.
What is a Vector?A vector is a quantity with both magnitude and direction in physics. It is often depicted by an arrow with the same direction as the amount and a length proportionate to the size of the quantity.
A vector lacks position, but has magnitude and direction. A vector is therefore unaffected by displacement parallel to itself as far as its length is unaltered.
As per the given data in the question,
4² + (-4)² = 16 + 16
= 32
Magnitude = √32
Magnitude = 5.65

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
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

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.

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
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 EHow to solve for the solutionFirst 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:
5x -4y = 76
Step-by-step explanation:
The point-slope form of the equation for a line is ...
y -k = m(x -h) . . . . . . line with slope m through point (h, k)
For the given point and slope, this equation is ...
y -(-9) = 5/4(x -8)
Multiplying by 4 gives ...
4y +36 = 5x -40
Subttracting 4y and adding 40 puts this into the desired form.

The measure of an exterior angle at C of isosceles triangle ABC is 110 degrees. If AC = BC, fine the measure of each angle of the triangle.
Answer:
110°, 35° and 35°
Step-by-step explanation:
Sum of internal angles of a triangle always is 180°
then,
180° - 110° = 70°
and it's an isosceles triangle, the other two angles are equals to 35° (70° / 2)
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)
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)

Find the volume of a box with the following measurements:
l=6cm
w=4cm
h=10 cm
1: 20 cm2
2: 20 cm
3: 240 cm2
4: 20 cm3
5: 240 cm
6:
240 cm3
Answer:
4: 20 cm3
Step-by-step explanation:
6 x 4 = 24
24 x 10 = 240
it is cubic since it is volume
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.

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