Answer:
D) $270.00
Step-by-step explanation:
15% of 1800 is 270 which is exactly what the dollar amount of the discount would be
Answer:
B: 3/4
Step-by-step explanation:
Since we know this is an exponential function
y= ab^x
where a is the initial value and b is the growth rate or what we multiply by
For the first point x=1 and y = 3/2
3/2 = a b^1
3/2 = a*b
For the second point x=2 and y = 9/8
9/8 = a b^2
Take the second equation over the first
9/8 = a b^2
-------------------
3/2 = a*b
3/4 = b
The growth rate is 3/4
That would also be know as the rate of change
Answer:
24 books
Step-by-step explanation:
Initially the top shelf has no books placed on
Then books added to this:
And now all 4 shelves have same amount of books. So total number is:
There are 24 books in the bookcase
Answer:
The reflection of point S across the y-axis is point <u> V </u>. The reflection of point Q across the x-axis and the y-axis is point <u> V </u>, whose coordinates are ( <u> -5 </u> , <u> -5.5 </u>).
===============================================
Explanation:
Point S is exactly 5 units away from the vertical y axis. Move from point S(5,-5.5) to the location (0,-5.5); ie move 5 units to the left. Then move another 5 units to the left to land on point V(5, -5.5)
Points V and S are the same distance away from the mirror line.
-----------------------
Reflecting point Q over the x axis lands us on point S. This time we move down 5.5 units to get to the x axis. Then move another 5.5 units to arrive at point S. As discussed above, point S then will reflect over the y axis to get to point V.
Side note: Combining two reflections produces a rotation. So effectively, going from Q to V is a rotation of 180 degrees.
