Answer:
the duration of this event is 4 hours
Step-by-step explanation:
This function is a quadratic one
let Δ be the dicriminant :
- a = -16
- b = 48
- c= 64
- Δ = 48²-4*(-16)*64 = 6400
so there are two values that satisfy -16t²+48t+64 = 0 x and y
- x= (-48+80)/-16*2 = -1
- y= (-48-80)/-16*2= 4
x<0 so w won't take it since time is a positive value here
so t = y = 4h
The answer would 80 square units for the trapezoid
Answer:
City A
Step-by-step explanation:
200 + 45 = 245
100 + 20 = 120
120 + 110 = 230
50 + 55 = 110
City A has the greatest tendency.
Solve the equation by inserting 7 for x.
Our equation is now y=2.5(7)-1.5
Multiply.
Y=17.5-1.5
Subtract
Y=16
The answer is D. 16
