Answer:
32. (E)stopped at 2pm
33. (A)
Step-by-step explanation:
32. on the graph you go across the x axis and find where the straight line starts and look for the time
33. look at the y-axis and see what line and the number it is on
Answer:
22. 3/8
23. 3/5
24. 0
Step-by-step explanation:
turn the 1 into a fraction for each of the problems.
for 22. it would be 8/8 because also trying to make the denominators the same.
8/8 - 5/8 = 3/8
try 23 and 24 now!
The vertex is at (2, 5).
To find the vertex, we first find the axis of symmetry; this is given by
x = -b/2a
For our equation, b = -16 and a = 4:
x = -(-16)/2(4) = 16/8 = 2
We substitute this back into our equation:
y = 4(2)² - 16(2) + 21 = 4(4) - 32 + 21 = 5
Therefore the vertex is at (2, 5).
A 30 hours per year
B 30X(100+20)%=36 per year
1.5 year later is 5.5 years
5.5X36=198 hours
