Answer:
$3685, the next model price will be $51315
Step-by-step explanation:
Answer:
7.385 minutes
Step-by-step explanation:
Given that :
Average speed = 65km/hr
The distance covered = 8km
The time taken Given the information above :
Recall:
Speed = distance / time
Time taken = distance / speed
Time taken = 8km / 65km/hr
Time taken = 0.1230769 hr
Time taken = 0.1230769 * 60 = 7.385 minutes
For f(x)=ax²+bx+c
if a is positive, then it is concave up and the verx is minimum
if a is ngative then it is concave down and vertex is maximum
hack: in form f(x)=ax²+bx+c, the x value of vertex is -b/2a
to find y value, just subsitutte that value for x in f(x)
so
y=-1x²+4x-4
negative, so vertx is max
x value of vertex is -4/(2*-1)=-4/-2=2
find f(2) or subsitute 2 for x
y=-1(2)²+4(2)-4
y=-1(4)+8-4
y=-4+4
y=0
maximum is 0
A is answer
I think this is right. Hope it helps
I think 745 dollars per month because the person he rent the mortgage cost like 350 dollars per week
