does this curved graph show a function explain how you know
Answer:
No; the graph fails the vertical line test.
The vertical line test is a tool used to determine if we have a function. If we can draw a single straight vertical line through more than one point on the red curve, then the graph is said to have failed the vertical line test. Consequently, this leads to the relation not being a function.
For this circle graph, we can draw a vertical line through more than one point, which is why we don't have a function here.
Put another way, there are inputs (x) that produce more than one output (y), so that's why we don't have a function.

if a runner is moving 2.88m/s directly north and accelerating at .350 m/s^2 at an angle of -52.0. At the point in the motion where she is running directly east what is the displacement
Answer:
19.1 m, 52.0°
Explanation:
Given:
v₀ₓ = 0 m/s
v₀ᵧ = 2.88 m/s
vᵧ = 0 m/s
aₓ = 0.350 m/s² cos(-52.0°) ≈ 0.215 m/s²
aᵧ = 0.350 m/s² sin(-52.0°) ≈ -0.276 m/s²
Find: Δx and Δy
First, find time.
vᵧ = aᵧt + v₀ᵧ
0 m/s = (-0.276 m/s²) t + 2.88 m/s
t = 10.4 s
Now find the displacement components Δx and Δy.
Δx = v₀ₓ t + ½ aₓ t²
Δx = (0 m/s) (10.4 s) + ½ (0.215 m/s²) (10.4 s)²
Δx = 11.7 m
Δy = v₀ᵧ t + ½ aᵧ t²
Δy = (2.88 m/s) (10.4 s) + ½ (-0.276 m/s²) (10.4 s)²
Δy = 15.0 m
The magnitude of the displacement is:
d² = Δx² + Δy²
d² = (11.7 m)² + (15.0 m)²
d = 19.1 m
The direction of the displacement is:
θ = atan(Δy / Δx)
θ = atan(15.0 m / 11.7 m)
θ = 52.0°

What is a graph?A graph is a visual depiction of statistical data or a logical relationship between variables. Graphs serve a predictive purpose because they have the virtue of displaying broad trends in the mathematical behavior of data. However, as just approximations, they may be incorrect and occasionally deceptive.
Most graphs have two axes, with the axis denoting a set of independent variables and the vertical axis denoting a set of dependent variables. The most typical graph is indeed a broken-line chart, where the regression coefficient is typically a factor of duration.
In the second graph the speed of every student is represented accurately, therefore the second graph is correct.

You testify as an expert witness in a case involving an accident in which car A slid into the rear of car B, which was stopped at a red light along a road headed down a hill (Fig. 6-25). You find that the slope of the hill is u " 12.03, that the cars were separated by distance d " 24.0 m when the driver of car A put the car into a slide (it lacked any automatic anti-brake-lock system), and that the speed of car A at the onset of braking was v0 " 18.0 m/s.With what speed did car A hit car B if the coefficient of kinetic friction was (a) 0.60 (dry road surface) and (b) 0.10 (road surface covered with wet leaves)
Answer:
A) 12.08 m/s
B) 19.39 m/s
Explanation:
A) Down the hill, we will apply Newton’s second law of motion in the downward direction to get:
mg(sinθ) – F_k = ma
Where; F_k is frictional force due to kinetic friction given by the formula;
F_k = (μ_k) × F_n
F_n is normal force given by mgcosθ
Thus;
F_k = μ_k(mg cosθ)
We now have;
mg(sinθ) – μ_k(mg cosθ) = ma
Dividing through by m to get;
g(sinθ) – μ_k(g cosθ) = a
a = 9.8(sin 12.03) - 0.6(9.8 × cos 12.03)
a = -3.71 m/s²
We are told that distance d = 24.0 m and v_o = 18 m/s
Using newton's 3rd equation of motion, we have;
v = √(v_o² + 2ad)
v = √(18² + (2 × -3.71 × 24))
v = 12.08 m/s
B) Now, μ_k = 0.10
Thus;
a = 9.8(sin 12.03) - 0.1(9.8 × cos 12.03)
a = 1.08 m/s²
Using newton's 3rd equation of motion, we have;
v = √(v_o + 2ad)
v = √(18² + (2 × 1.08 × 24))
v = 19.39 m/s

A speeding Thunderbird left skid marks on the road that were 76.7 m long when it came to a stop. If the acceleration of the car was -10 m/s2, how fast was the car initially going?
Answer: 39.2 m/s
Explanation:
You can use the kinematic equation:
[tex]v_f^2=v_i^2+2a*d[/tex]
We know the final velocity because it says it came to a stop. So now all we gotta do is plug in.
[tex]0^2=v_i^2+2(-10)(76.7)\\v_i^2=1,534\\v_i=\sqrt{1534} \\=39.166 m/s[/tex]
What happens to the temperature of a substance while it is changing state?
A. It increases first and then decreases.
B. It decreases first and then remains constant.
C. It varies randomly.
D. It remains constant.
Answer:
During a phase change, the temperature will remain constant. Obviously all the heat is used in phase transformation. So the correct answer should be D. Forgive me if I'm wrong but I hope this helps!
The temperature of a substance remains constant while it is changing state. Thus, the correct option is D.
What is the relation between state and temperature of substance?Temperature has a direct effect on whether a substance exists in states as a solid, liquid, or gaseous substance. Substances can change their phase often because of a temperature change of the substance. At very low temperature conditions, most of the substances are solid, as the temperature of the substance keeps on increasing, then they become liquid and at very higher temperatures still, they become gaseous substances.
The temperature of a substance remains constant while it is changing its state.
Therefore, the correct option is D.

Answer:
Sling Psychrometer
Explanation:
A sling psychrometer measures relative humidity through the process of evaporation. It contains two thermometers. The cloth around one of the thermometers is wetted and slung around in the air so the moisture evaporates, which has a cooling effect. The relative humidity is then calculated using the difference in temperature for the two thermometers.

Two ice skaters on ice push away from each other. What will be the effect of the forces of their pushing each other if their masses are different?

Answer:If the masses are different, the lighter ice skater will accelerate faster than the ice skater with more mass.
Explanation:
The lighter skater will accelerate more quickly than the heavier skater if there are mass discrepancies.
used an idea?According to Newton's third law, the action and reaction forces in any force interaction must be equal and moving in the opposite directions. These pressures, nevertheless, affect a variety of items. In this case, each skater will experience the same amount of force, and if any other horizontal forces, such as friction, operating on each skater in the opposite direction from the pushing force are less than the pushing force, each will accelerate in that direction. The two skater system's center of mass will remain where it is if there is little to no friction to prevent the skaters from moving.

Answer:
Gold

Mixture
Explanation:
Density
The density of an object of mass m and volume V is given by:
[tex]\displaystyle d=\frac{m}{V}[/tex]
We are given the following densities:
Gold: 19.3 gr/cm3
Silver: 10.5 gr/cm3
With the data provided in the table, we can confirm which of the three columns corresponds to gold, silver, or a mix of both.
Calculating the first density: m1=1,930 gr, V1=100 cm3
[tex]\displaystyle d1=\frac{m1}{V1}[/tex]
[tex]\displaystyle d1=\frac{1,930}{100}[/tex]
[tex]d1=19.3\ gr/cm^3[/tex]
This crown is made of gold
Calculating the second density: m2=1,930 gr, V2=184 cm3
[tex]\displaystyle d2=\frac{m2}{V2}[/tex]
[tex]\displaystyle d2=\frac{1,930}{184}[/tex]
[tex]d2\approx 10.5\ gr/cm3[/tex]
This crown is made of silver
Calculating the last density: m3=1,930 gr, V3=150 cm3
[tex]\displaystyle d3=\frac{m3}{V3}[/tex]
[tex]\displaystyle d3=\frac{1,930}{150}[/tex]
[tex]d3\approx 12.9 gr/cm^3[/tex]
Since the value of the density is between gold and silver, this crown is a mixture.
