You X to the second power.. 4 to the second power is 16 and 16-16=0 so x=4
Answer:
2.5 miles
Step-by-step explanation:
22.50-6=16.50
16.50÷3=5.5
Y=-6(10)+15
y=-60+15
y=-45
y=-120+15
y=-105
range equals -105 to 45
To find it, evaluate it at the endpoints and the vertex
in form
f(x)=ax²+bx+c
the x value of the vertex is -b/2a
given
c(t)=1t²-10t+76
x value of vertex is -(-10)/1=10
evaluate c(0) and c(13) and c(10)
c(0)=76
c(13)=115
c(10)=76
it reached minimum in 2000 and 2010
porbably teacher wants 2010
the min value is $76
