Answer:
8420
Step-by-step explanation:
10 to the third power will move the decimal point three place values to the right. So, the first two times you move it, you get 842, and so there is a 0 on the end to signify that it moved the third time.

What is the equation in slope-intercept form of the line that passes through the points ( -4, 47) and ( 2 , -16)?
Answer:
[tex]-\frac{21}{2} x+5[/tex]
Step-by-step explanation:
To find the slope of the equation, you use [tex]\frac{rise}{run}[/tex] , or [tex]\frac{y_{2} - y_{1}}{x_{2} - x_{1}}[/tex] :
[tex]\frac{-16-47}{2+4}[/tex]=[tex]\frac{-63}{6}[/tex]=[tex]\frac{-21}{2}[/tex]
Then you have to find the y intercept. First, plug in the x of a point and solve:
[tex]\frac{-21}{2}[/tex] * 2= -21
Then, find the distance between the answer and the y of the given point. Since our answer is smaller than the y of the point, we'll get a positive y- intercept.
21-16=5
This will give us the equation:
[tex]-\frac{21}{2} x+5[/tex]

An elevator rises steadily up a skyscraper. After 4 s it is 33 m above the ground, 2 s later it is 47 m above the ground. Which equation models its position, y, with respect to time, x?
A. y-47= -7(x-2)
B. y+33=7(x+4)
C. y-33= -7(x-4)
D. y-33=7(x-4)
Answer:
C
Step-by-step explanation:
It would be c i took the test:)
The required equation model would be y - 33 = -7(x -4) which is the correct answer would be option (C).
What is the slope of the line?A line's slope is defined as its inclination. It is denoted by m
Slope m = (y₂ - y₁)/(x₂ -x₁ )
Consider Points 1 and 2 on a line. Point 1's coordinates are (x₁ , y₁), and Point 2's coordinates are (x₂, y₂).
Given that the continuously rising building is an elevator. It is 33 meters above the ground after 4 seconds, and 47 meters above the earth after 2 seconds.
Let the required equation model would be as:
y - y₁ = (y₂ - y₁)/(x₂ -x₁ )[x₂ -x]
x₁ = 4, y₁ = 33
x₂ = 2, y₂ = 47
⇒ y - y₁ = (y₂ - y₁)/(x₂ -x₁ )[x₂ -x]
Substitute values in the equation, we get
⇒ y - 33 = (47-33)/(2-4 )[x -4]
⇒ y - 33 = 14/(-2 )[x -4]
⇒ y - 33 = -7(x -4)
Therefore, the equation model is y - 33 = -7(x -4).

The graph shows the equation y = 2x – 3. Use the slider for a to move the vertical line on the graph. Based on the vertical line test, is this equation a function? Why or why not?
Answer:
Yes. The vertical line never touches the graph at more than one point at the same time.
Step-by-step explanation:
this is the plato and edmentum answer
(make sure this is the right question)
As the vertical line touches the graph of the equation y = 2x - 3 it is a function.
What is a graph?The set of ordered pairings (x, y) where f(x) = y makes up the graph of a function.
These pairs are Cartesian coordinates of points in two-dimensional space and so constitute a subset of this plane in the general case when f(x) are real values.
Given, An equation y = 2x - 3.
Now, If we draw a vertical line and it touches the graph at only one point
the equation is a function but if the vertical line touches the graph at more than two points the equation is not a function.

Kari and Samantha have determined that their water-balloon launcher works best when they launch the balloon at an angle within 3 degrees of 45 degrees. Which equation can be used to determine the minimum and maximum optimal angles of launch, and what is the minimum angle that is still optimal?
|x – 3| = 45; minimum angle: 42 degrees
|x – 3| = 45; minimum angle: 45 degrees
|x – 45| = 3; minimum angle: 42 degrees
|x – 45| = 3; minimum angle: 45 degrees
Answer: C |x – 45| = 3; minimum angle: 42 degrees
Step-by-step explanation:
The equation which can be used to determine the minimum and maximum optimal angles of launch and the minimum angle that is still optimal is |x – 45| = 3 and 42 degrees respectively.
What is an Angle?This is formed when two straight lines meet at a common endpoint and are also formed during intersection of planes.
In this scenario we were told the angle is within 3 degrees of 45 degrees which means the minimum angle is 45 degrees - 3 degrees = 42 degrees with the equation used to determine the minimum and maximum being |x – 45| = 3 as the maximum angle and deviation has to be present in the equation.

Answer: 40.87
Step-by-step explanation:
Answer: 40.87
Step-by-step explanation:
First you would do 12.8x3 because it’s in parentheses you would then get 18.75 + 38.4 - 16.28. You would then do 18.75 + 38.4 and get 57.15 then subtract 16.28 from that and get your final answer 40.87
Number 9 please is each triangle a right triangle? EXPLAIN
It is not because a right triangle needs one right angle, and a right angle is 90 degrees
Step-by-step explanation:
Answer:
A right triangle is a triangle in which one of the angles is a 90∘ angle.
Step-by-step explanation:
The "square" at the vertex of the angle indicates that it is 90 degrees. A triangle can be determined to be a right triangle if the side lengths are known. If the lengths satisfy the Pythagorean Theorem (a2+b2=c2) then it is a right triangle.

estimate 8.2x6.7 divided by 0.46
Answer:
Well, the correct answer is 119.4347826086956521739130 (after the 130 the whole decimal is repeated.
Step-by-step explanation:
Although if your assignment is asking for an estimate you could probably just say 119 since the first and second decimal is less then 5
The estimation of the expression 8.2 × 6.7 divided by 0.46 is approximately 112.
What is estimation?It is a rough calculation of the value, number, quantity, etc. It doesn't use real calculation but estimation by some method like prediction, using approximation etc.
For this case, we've to esimate the value of the expression:
[tex]E = \dfrac{8.2 \times 6.7}{0.46}[/tex]
Instead of using exact values, let we use:
[tex]8.2 \approx 8\\6.7 \approx 7\\0.46 \approx 0.5 = 1/2[/tex]
Then, we get:
[tex]E = \dfrac{8.2 \times 6.7}{0.46} \approx \dfrac{8 \times 7}{1/2} = 2 \times 8 \times 7= 2 \times 56 = 112[/tex]
Thus, the estimation of the expression 8.2 × 6.7 divided by 0.46 is approximately 112.
