Given that Sienna planned a rectangular pool drawn on a scale 11 inches long by 7 inches wide, and Sienna used the scale drawing above to create a pool that is 14 ft wide x 22 ft long, and she then decided to make a pool with a final length of 33 ft, to determine which expression finds the change in scale factor for the longer pool Sierra is building the following calculation must be performed:
11 inches = 0.916 feet 11 / 0.916 = 12 7 inches = 0.583333 feet 7 / 0.5833333 = 12 Thus, the initial scale is 1:12. 33 / 0.916 = 36
Therefore, the scale factor went from 1:12 to 1:36.

If I was to sketch the graph of y=4x+2
What would the graph look like?
Would it be a straight line or a curved line?
Where would it cross the y-axis?
What does 4 in 4x tell us?
Answer:
see explanation
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
y = 4x + 2 ← is in slope- intercept form
Thus its graph is a straight line
crosses the y- axis at (0, 2 ) , that is c = 2
the 4 in 4x is the slope m of the line

Find the measure of each angle indicated.
A) 21°
C) 23
E) 25°
B) 80°
D) 20°
Answer:
D) 20⁰
Step-by-step explanation:
EDF = 180-100=80⁰
EFD= 80⁰+80⁰=160⁰
180⁰-160⁰=20⁰
Answer:
I would say D, 20°
Step-by-step explanation:
angles on a straight line should be equal to 180°. so 180 -100 = 80° inside.
angles inside a triangle should also be 180. So, 80° + 80° =160°. to get the other angle subtract 160 from 180 to get 20°

Plot C (-4,-5). D(-4,3), E (-3,2), and F(-8,2) in a coordinate plane. Are CD and EF congruent?
Answer: No
Step-by-step explanation:
1. The distance between C (-4,-5) and D (-4,3) is 8
2. The distance between E (-3,2) and F (-8, 2) is 5
3. Since the measurements are not the same, the segments cannot be
congruent

x → ∞ y → ∞ and as x →- ∞ y → -∞ is the end behavior of the graph of the polynomial function y = 10x⁹ – 4x
What is Graph?Graph is a mathematical representation of a network and it describes the relationship between lines and points.
The meaning of end behavior is how the function ‘y’ (in this case) moves when x tends towards both ∞ and - ∞.
As x → ∞ y → ∞.
This is apparent from the upward movement of the graph of the function y=10x⁹ –4x
As x →- ∞ y → -∞
This inference is also drawn from the above graph i.e. as x values become more negative the graph of y also travels towards infinity i.e. southward on the LHS of the above graph.
Even though the graph of the function remains flat in between x = -4 to x = 4.
After these points, the graph moves towards infinity exponentially.
Hence, x → ∞ y → ∞ and as x →- ∞ y → -∞ is the end behavior of the graph of the polynomial function y = 10x⁹ – 4x
