Answer:
Coordinate of B: (3, -5)
Coordinate of C: (3, 5)
Coordinate of D: (0, -1)
Step-by-step explanation:
Point A is (-2, -5).
The distance between line AB is 5 units.
The distance between line BC is 10 units.
To find the point for B, the distance is 5 units on the x axis.
The x point for point B is -2 + 5 which is 3 units. x = 3
The y point doesn't change, so the coordinate of point B is (3, -5).
___________________________________________________________
The distance between line BC is 10 units.
To find the point of C, the distance is 10 unites on the y axis.
The y point for point b is -5 + 10 which is 5 units. y = 5
The x point doesn't change, so the coordinate of point C is (3, 5).
___________________________________________________________
We find an equation for line AC. The equation is y = mx + b.
Y is any y point on the line. X is any x point on the line. M is the slope of the line. B is the y-intercept of the line.
Since D is right on the y axis, this means that the x point of D is 0.
Point C is (3, 5) and point A is (-2, -5).
We use (y2 - y1) / (x2 - x1) and substitute. Y is the y point and x is the x point.
(5 - (-5)) / (3 - (-2)) = 10 / 5 = 2
The slope of the line is 2.
With this, we get the equation of y = 2x + b
We insert one of the random x point and y point which (in this case) I choose (3, 5).
Substituting, we get -
5 = 2 * 3 + b
5 = 6 + b
b = 5 - 6
b = -1
So the y-intercept of the graph is -1 and for the graph, we get -
y = 2x - 1
D is already the line of the y-intercept, but we can make sure by inserting the x point as 0.
y = 2 * 0 - 1
y = 0 - 1
y = -1
The coordinate of point D is (0, -1).

-16t^2+80t+4=100
Answers
Answer:
Step-by-step explanation:
Good job on creating a testable equation.
Maybe you need to know what to do with it.
If we can find a real solution or two, then the projectile will reach the 100 ft altitude. (I'm fairly certain it will given that high initial velocity)
If we cannot find a real solution, then the rocket will fail to reach the altitude goal.
-16t² + 80t + 4 = 100
we will want a zero on the right hand side, so subtract 100
-16t² + 80t - 96 = 0
we can simplify even further by dividing everything by -16
t² - 5t + 6 = 0
which can be factored
(t - 3)(t - 2) = 0
so either
t = 3 s
or
t = 2 s
So the projectile reaches the 100 ft level twice,
at two seconds after launch while rising and
at three seconds after launch while falling.
Lets see what happens when we set the goal a bit higher, say 108 ft
-16t² + 80t + 4 = 108
-16t² + 80t - 104= 0
-2t² + 10t - 13 = 0
not easily factored so let's use quadratic formula
t = (-10 ±√(10² - 4(-2)(-13))) / (2(-2)
t = (-10 ±√-4) / -4
As √-4 = 2i is an imaginary number, there are no real solutions and the projectile will not reach 108 ft.

Find the critical value zα/2 that corresponds to a 83% confidence level
Answers
The critical value zα/2 that corresponds to a 83% confidence level is 1.37.
The z score is used to determine by how many standard deviations the raw score is above or below the mean. The z score is given by:
[tex]z=\frac{x-\mu}{\sigma} \\\\where\ x=raw\ score,\mu=mean,\sigma=standard\ deviation[/tex]
Given that the confidence level (C) = 83% = 0.83
α = 1 - C = 0.17
α/2 = 0.17/2 = 0.085
The z score of α/2 corresponds with the z score of 0.415 (0.5 - 0.085) which is equal to 1.37

9. Modeling Real Life A machine that

7,829 toy spinners in 1 day. About how many toy spinners does the machine make each hour?
Answers
Answer:
8 hours = 7,829 toy spinners
24 hours= x toy spinner
7829 / 24 x 8
2069 for one hour
Step-by-step explanation:
so your answer is this hope this helps good luck if it does not i am sorry
The number of toy spinners the machine make each hour is 2068.
Given that, the machine makes 7,829 toy spinners in 1 day.
What is the unitary method?The unitary method is a technique for solving a problem by first finding the value of a single unit, and then finding the necessary value by multiplying the single unit value.
Here,
8 hours = 7,829 toy spinners
24 hours= x toy spinner
Now, number of toys in one hour = 7829/(24×8)
= 2069.66
= 2069 per one hour
Therefore, the number of toy spinners the machine make each hour is 2069.

How do I show my work for solving the radius of a circle if the area is 78.5 cm^2
(I already know the answer is 5 cm)
Answers
9514 1404 393
Answer:
radius = 5 cm
Step-by-step explanation:
The point of "show your work" is to have to do exactly that. If you know the answer to the problem, you are being requested to show how you got it. If you got it by using a web calculator, then show your input and its result.
__
If you worked the problem yourself, you probably did it by filling in numbers in the equation for the area of a circle:
A = πr²
78.5 = 3.14×r²
Dividing both sides by 3.14 gives the square of the radius:
78.4/3.14 = r² = 25
Taking the positive square root gives the radius:
r = √25 = 5
The area is in square centimeters, so the radius is in centimeters:
radius = 5 cm

Magnets work because opposite poles are attracted to each other, this is how the objects move (depending on how the atoms and how to iron is, it could be much stronger or weaker)
If there is a system of magnets there is potential energy, when you let go of the magnets (or when they stick together) it converts the potential energy to kinetic energy because it moved.
