Answer:
im failing math
Step-by-step explanation:
Answer:
The vertex of a parabola is found by
'h' position = -b / (2 * a) = 0 / 2 * -4 = 0
'y' position = ah^2 + bh + c = -4*0 + 0 -20
vertex = (0, -20)
Step-by-step explanation:
Ok so I assume
28 and decreased by 12.5%
percent means partst out of 100 so
12.5%=12.5/100=0.125
first find 12.5% of 28 then subtract
0.125 times 28=3.5
decrease
28-3.5=24.5
answer is 24.5
Answer:
The answer to your question is Ф = 45°
Step-by-step explanation:
Data
A (1, 4)
B (-1, 2)
Process
1.- Find the slope of the line
formula
m =
Substitution
m =
Slope definition, is the steepness of a line and also is the tangent of the angle of the line.
tangent Ф = slope
tangent Ф = 1
Ф = tangent⁻¹ 1
Ф = 45°
Answer:
15
Step-by-step explanation:
So, between 14 and 15 would be where 14 5/6 is at. But, 14 3/6 would be directly in the middle of the two. Since 14 5/6 is greater than 14 3/6, it would round up to 15 instead of rounding down to 14.
