What is Acceleration ?Acceleration is the change of speed with respect to time.
It is given that ,
The mass of the person is 50kg
Weight is 490 N
He has boarded an elevator with a bathroom scale.
1. The elevator is going down at constant speed , Force = 0N as acceleration is zero , The reading is 50kg.
2. The elevator is going up an slowing down . The magnitude of the acceleration is 4.9 m/sq.s , Force = mass * acceleration = 50 * 4.9 = 245N acting upward but the net force will be acting downward.
490 - 245 = 145N , reading 14.79 kg.
3.The elevator is free falling with an acceleration of 9.8m/sq.s force 0 N , as the gravitational force is pulling you down and the scale pushes up with the same force , Reading is 0 kg.

On a coordinate plane, a graph shows Street on the x-axis and Avenue on the y-axis. A line is drawn from Tia to Lei. Tia is at (4, 8) and Lei is at (12, 20).
Tia lives at the corner of 4th Street and 8th Avenue. Lei lives at the corner of 12th Street and 20th Avenue. The fruit market is Three-fourths the distance from Tia’s home to Lei's home.
x = (StartFraction m Over m + n EndFraction) (x 2 minus x 1) + x 1
y = (StartFraction m Over m + n EndFraction) (y 2 minus y 1) + y 1
Where is the fruit market?
6th Street and 11th Avenue
10th Street and 17th Avenue
9th Street and 15th Avenue
8th Street and 14th Avenue
Answers
Answer:
The Fruit market is at - 6th Street and 11th Avenue
Step-by-step explanation:
Distance is a numerical measurement of how far apart objects or points are. to find the distance between two points is the length of the line segment connecting them we use distance formula.
for example :-
if (x, y) and (p, q) are the two points joining the line segment then distance between them is given by the formula :-
[tex]\sqrt{(p- x)^2 + (q-y)^2}[/tex] this is known as the distance formula.
using the above formula :
distance between points (4, 8) and (12, 20) is:
[tex]\sqrt{(12-4)^2 + (20-8)^2}[/tex]
√(8² + 12²)
√208
14.42
Now the fruit market is Three-fourths the distance between Tia’s home to Lei's home.
therefore,
3/4×14.42 = 10.8
now we can check that option (A ) i.e. (6, 11) distance from lei home i.e. (12, 20) is equal to 10.8
hence the fruit market is at the = 6th Street and 11th Avenue

In calm water, the motorboat of Jana is moving at the speed of 16.5km/h. On a river, because of the current, the boat moves faster down the river only by raising it. Jana went up the river in 5 hours and the decent in only 2 hours. What is the speed of the current?
Answers
Answer: 707 km/h
Step-by-step explanation:
let c = speed of current
16.5 + c = speed of sailboat downstream
16.5 - c = speed of sailboat upstream
distance = travel time * speed
﹋﹋﹋﹋﹋﹋﹋﹋﹋﹋﹋﹋﹋﹋﹋﹋﹋﹋﹋

To determine if a point is a solution to a system of equations, you need to determine if the point is a solution to both equations.
Is ( 2,10) a solution to -3x-4y = 4
Substitute into the equation and see if it is true
-3(2) -4(10) = 4
-6 -40 = 4
-46 =4
This is not true so it is not a solution
Answer:
No
Step-by-step explanation:
The solution(s) of a system is/are the point(s) (x, y) where the lines intersect.
The question asks if (2, 10) is a solution of the system. This means the "x" value is "2" and the "y" value is "10".
We can substitute those values into both of the equations.
[tex]-3x-4y=4\\-3(2)-4(10)=4\\-6-40=4\\-46=6 \Rightarrow Incorrect![/tex]
The "x" and "y" values must be true for both equations, therefore (2, 10) is not a solution of the system.

The system of equations ( shown in the pic i uploaded) can be used to represent this situation. A. Find how much does a box of oranges and a box of cherries cost ?
Answers
Answer:
Let the cost of orange be X and cost of cherry be y
3x + 9y = 78
8x + 4y = 58
Solving equation using elimination method
multiplying eq 1 with 8 and eq 2 with 3
8(3x + 9y ) = 78(8)
3( 8x + 4y) = 3(58)
24x + 72 y = 624
24x + 12y = 174
subtracting,
60 y = 450
y = 7.5
3x + 9(7.5) = 78
3x + 67.5 = 78
3x = 78 - 67.5
3x = 10.5

The new function (fog)x will be x - 2.
What is the function?A relationship between a group of inputs and one output is referred to as a function. In plain English, a function is an association between inputs in which each input is connected to precisely one output. A domain, codomain, or range exists for every function. Typically, f(x), where x is the input, is used to represent a function.
To find (f g)(x), we need to evaluate f(g(x)).
First, we need to find g(x):
g(x) = x - 4
Next, we substitute g(x) into f(x):
f(g(x)) = f(x - 4)
Now we can simplify:
f(x - 4) = (x - 4) + 2
f(g(x)) = x - 2
Therefore, (f g)(x) = x - 2.

Express it in slope-intercept form.
Answers
The equation of the line in slope-intercept form is y = (1/2)x + 3 and the slope is 1/2.
What is a straight line?A straight line is a combination of endless points joined on both sides of the point.
The slope 'm' of any straight line is given by:
[tex]\rm m =\dfrac{y_2-y_1}{x_2-x_1}\\[/tex]
As we can see in the graph the line goes from (-6, 0) and (0, 3)
Finding the slope:
[tex]\rm m =\dfrac{3-0}{0-(-6)}\\[/tex]
m = 3/6 = 1/2
y = mx + c
y = (1/2)x + c
c is the y-intercept
c = 3
The equation:
y = (1/2)x + 3
Thus, the equation of the line in slope-intercept form is y = (1/2)x + 3 and the slope is 1/2.

use the graph below to answer this question: find the average rate of change for the given function from x=1 to x=2.
Answers
Answer: D. 2
Step-by-step explanation:
The question is asking for the rate of change from x=1 to x=2. Remember that the rate of change is also the slope, which can be seen as [tex]\frac{rise}{run} or \frac{y}{x}[/tex]. The rise would be going up/down the graph and the run would go left/right of the graph. Let's look at where x=1 and x=2 on the graph.
First, look at where the line falls between x=1 and x=2. Then, on where x=1, go up, then right on the graph, until you find the point where x=2. In this case, the rise over run is [tex]\frac{2}{1}[/tex]. This can be simplified to 2.
Therefore, the answer is 2.
