Answer:
Step-by-step explanation:
Not QUITE a parabola . but up until y = 4 it is close
Vertex = (-7-10)
Vertex form of parabola
y = a ( x+7)^2 -10 find a integer-coordinat point to calculate 'a'
I'll use -18,0
0 = a(-18+7)^2 -10
0 = 122 a -10 a = 10/122
y = 10/122 (x+7)^2 - 10 see graph below:
Answer:
A: True
B, C and D: False
Step-by-step explanation:
We have a total sales tax for Alabama that is:
The total sales tax for Florida is:
The total sales tax is greater in Florida than in Alabama.
A. The furniture set is cheaper in Alabama, because the amount of sales tax will be lower by about $8. TRUE
The sales tax difference in this purchase can be calculated as:
B. The furniture set is cheaper in Florida, because the amount of sales tax will be lower by about $10. FALSE (it is cheaper in Alabama)
C. The furniture set is cheaper in Alabama, because the amount of sales tax will be lower by $10. FALSE (the sale tax in Alabama is $129)
The amount of sales tax in Alabama is:
D. The furniture set costs the same in either state, because the amount of sales tax will be the same for the two locations. FALSE (it is not the same in both states).

Step-by-step explanation:
Answer:
Vertical change in the elevation is 1.06 miles.
Step-by-step explanation:
Distance between the surveyor C and the point A on a mountain = 5 miles
Angle of elevation of the point A from surveyor = 12°
We have to calculate the vertical height AB of the point A from the surveyor.
tan C =
tan 12° =
tan 12° =
h = 5tan12°
h = 1.063 miles
h ≈ 1.06 miles
Therefore, vertical change in the elevation is 1.06 miles.
