The amount or the strength of force is called its magnitude.
Step-by-step explanation:
Hope it helps you !!The amount or the strength of force is named magnitude.
What is force?Force is that the push or pull on an object with mass that causes it to alter its velocity. Force is an external agent capable of adjusting the state of rest or motion of a selected body. it's a magnitude and a direction.
How to identify strength of force?The term which is true is magnitude. The magnitude of a force is expressed within the SI unit of force called Newton. 1 Newton is that the force which might make an object of 1 kilogram mass to at a speed of 1 meter per second. Magnitude is essentially the most extent of size and also the direction of an object. Magnitude is employed as a typical think about vector and scalar quantities. Magnitude of earthquake is measured by Richter scale.
Hence the number or the strength of force is named its magnitude.

Determine if the given ordered triple is a solution of the system.
(4, -5, -4)
4x + 2y + z = 2
5x - 4y - z = 44
3x + y + 4z = -9
Answer:
It is.
Step-by-step explanation:
(x, y, z) => (4, -5, -4)
substitute 4 in x, -5 in y & -4 in z for all the equations in the system.
4x + 2y + z = 2
4(4) + 2(-5) - 4 = 2
2 = 2
5x - 4y - z = 44
5(4) - 4(-5) - (-4) = 44
44 = 44
3x + y + 4z = -9
3(4) + (-5) + 4(-4) = -9
-9 = -9
All equations therefore agree with the ordered triple.

Find the shortest distance between the start and end points . 15 miles O 24 miles 28.3 miles 32.8 miles
The distance between the start and end points is 28.3 miles.
How to find the distance?
Remember that the distance between two points (x₁, y₁) and (x₂, y₂) is:
[tex]d = \sqrt{(x_1 - x_2)^2 + (y_2 -y_1)^2}[/tex]
Here the initial point is (0mi, 0mi).
If we define the north as positive y-axis and east as the positive x-axis, after that Thomas travels 24 miles north and 15 miles west his new position is:

Assume that the amounts of weight that male college students gain during their freshman year are normally distributed with a mean of 2.9 lb and a standard deviation of 10.4 lb. Find the probability that a randomly selected male college student gains 15 lb or more during their freshman year. What does the result suggest about the claim of the "freshman 15"?
The probability that a randomly selected male college student gains 15 lb or more during their freshman year is 11.6%
What is Probability ?Probability is defined as the likeliness of an event to happen.
Let X be a random variable that shows the term "freshman 15" that claims that students typically gain 15lb during their freshman year at college.
It is given that
X follows is a normal distribution with a mean of 2.1 lb (μ) and a standard deviation (σ) of 10.8 lb.
Population Mean (μ) = 2.1
Population Standard Deviation (σ) = 10.8
We need to compute Pr(X≥15). The corresponding z-value needed to be computed is:
[tex]\rm Z_{lower} = \dfrac{ X_1 -\mu }{\sigma}\\\\Z_{lower} = \dfrac{ 15-2.1 }{10.8}\\\\\\Z_{lower} = 1.19[/tex]
Then the probability is given as

The equation of the parabola is y = 2/25x^2 + 2
How to determine the parabola equation?The complete question is in the image
The given parameters are:
Vertex, (h, k) = (0,2)
Point (x,y) = (-5, 4)
The parabola is represented as;
y = a(x - h)^2 + k
Substitute (h, k) = (0,2)
y = a(x - 0)^2 + 2
This gives
y = ax^2 + 2
Substitute (x, y) = (-5,4)
4 = a(-5)^2 + 2
This gives
4 = 25a + 2
Subtract 2 from both sides
25a = 2
Divide by 25
a = 2/25
Substitute a = 2/25 in y = ax^2 + 2
y = 2/25x^2 + 2
Hence, the equation of the parabola is y = 2/25x^2 + 2

What is Demand Function?A demand function describes the mathematical relationship between the quantity demanded and one or more determinants of the demand, as the price of the good or service, the price of complementary and substitute goods, disposable income, etc.
Here, given differential equation;

Supplementary angles add to 180 degrees
Let the supplement be x
x+165 = 180
x +165-165= 180-165
x = 15
The supplement is 15
Answer:
Hello! The answer is 15°.
Step-by-step explanation:
Supplementary angles add up to 180°.
To find the measure of each angle, we can now set up an equation because we have the total that supplementary angles add up to:
x + 165 = 180
Now, we can subtract 165 from both sides to get x by itself:
x + 165 = 180
-165 -165
This leaves us with:
x = 15
