The elevator that takes passengers from the lobby of the John Hancock Centre in
Chicago to the observation level travels 300 feet in 5 seconds. The observation level
is located on the 100th floor, at 1200 feet above the ground. Find the time it takes
the elevator to travel from the lobby to the observation level. (4)
Answer:
20 seconds
Step-by-step explanation:
s = Distance traveled by elevator = 300 ft
t = Time taken = 5 seconds
Velocity is given by
[tex]v=\dfrac{s}{t}\\\Rightarrow v=\dfrac{300}{5}\\\Rightarrow v=60\ \text{ft/s}[/tex]
Distance to the observation level from the lobby = 1200 ft
Time taken is given by
[tex]t=\dfrac{1200}{60}\\\Rightarrow t=20\ \text{s}[/tex]
Time taken to reach the observation level from the lobby is 20 s.
If ΔABC is reflected across the y-axis, what are the resulting coordinates for points A', B', and C'
sketch the reflection on the cordinate plan
Answer:
Step-by-step explanation:
Reflection across the y axis changes the x value.
Reflection across the x axis changes the y value.
This is counterintuitive, but it is correct.
A'
(-1,6)
B'
(-2,1)
C'
(-5,2)
Do you see what happened. All the values for x become - values because you are moving an equal distance in the -x direction

what is 300 × = 120,000
there is nothing between the × and = cuz its asking me 300× what = 120,000.
The answer is 400
First, you must flip the equation.
[tex]120000[/tex] ÷ [tex]300[/tex] = ?
Then, you must simplify the equation.
[tex]1200[/tex] ÷ [tex]3[/tex] = ?
Finally, divide the two terms.
[tex]1200[/tex] ÷ [tex]3[/tex] = 400

Write the equation in vertex form using the following information: vertex (4, -6) and a=1.
Submit
Answer:
y = (x - 4)² - 6Step-by-step explanation:
An equation of a quadratic function in a vertex form is y=a(x-h)²+k, where vertex is (h, k)
vertex (4, -6) means h = 4 and k = - 6
So:
y = 1(x - 4)² + (-6)
y = (x - 4)² - 6

2 5. 8 11 X 2 -4 8 у 14 What is the equation of the given table?
Answer:
8-6+-2
Step-by-step explanation:
Which equation should you use to solve for x?
40°
60°
16x
O 60 + 16x + 40 = 180
O 60 + 40 = 16x
0 60 + 16x = 40
O 60 + 16x + 40 = 90
Answer:
1st Option
Step-by-step explanation:
All angles in a triangle must add up to 180°.
Step 1: Set up equation
40° + 60° + 16x = 180°
Step 2: Rewrite
60° + 16x + 40° = 180°
Answer:
Option: A.
Step-by-step explanation:
Hey there!
In the given triangle;
60° +16x° + 40° = 180° { Sum of interior angle of a triangle}
100° + 16x= 180°
16x = 180° - 100°
[tex]x = \frac{80}{16} [/tex]
Therefore, X= 5°.
So, Option A (equation) is used for solving the value of"X".

Determine the height of the triangle if the area is 24 square inches and the base is 12 inches.
Answer:
4
Step-by-step explanation:
We use 1/2base times height to find the area and since we already have an area we just do 24= 6h then we divide 6 on both sides and height equals 4
Answer: 6 inches
Step 1: Subtract 12 because 12 iches is the base.
24 - 12 = 2
Step 2: Divide 12 by 2 because triangles have two equal sides.
12 ÷ 2 = 6
Answer = 6

Answer:
n = -1 n = -7
Step-by-step explanation:
5| 2n+8| +3 = 33
Subtract 3 from each side
5| 2n+8| +3-3 = 33-3
5| 2n+8| = 30
Divide by 5
5/5| 2n+8| = 30/5
| 2n+8| = 6
An absolute value equation has two solutions, one positive and one negative
2n+8 = 6 2n+8 = -6
Subtract 8 from each side
2n+8-8=6-8 2n+8-8 = -6-8
2n = -2 2n = -14
Divide by 2
2n/2 = -2/2 2n/2 = -14/2
n = -1 n = -7

A parabola has a vertex of (-2,1) and passes through the point (0,-7). What is the value of amplitude
Answer:
The value of the amplitude is -2
Step-by-step explanation:
The given parameters are;
The vertex of the parabola = (-2, 1)
The point through which the parabola passes = (0, -7)
The equation of the parabola can be expressed as follows;
y - y₀ = a·(x - x₀)²
Where;
y₀ = The y-coordinate of the vertex = 1
x₀ = The x-coordinate of the vertex = -2
Therefore, we substitute the known values of the coordinates of a point the parabola to get;
-7 - 1 = a·(0 - (-2))²
-8 = 4·a
a = -8/4 = -2
The value of the amplitude a = -2.

(13/7)^2 as a simplified proper fraction or a simplified improper fraction?
Answer:
Simplified improper fraction.
Step-by-step explanation:
A simplified proper fraction would not have a numerator bigger than the denominator.
An improper fraction would have a numerator bigger than the denominator that can be simplified.
We see here that the expression isn't proper as it can be simplified further. Therefore, it is improper.
Answer: Simplified improper fraction.
