Answer:
The zeros are x=1, x=-6
Step-by-step explanation:
f(x) =x^2+5x-6
Factor: What two numbers multiply to -6 and add to 5
-1 *6 = -6
-1 +6 = 5
f(x) = (x-1) (x+6)
Using the zero product property
0 = (x-1) (x+6)
x-1 =0 x+6=0
x=1 x=-6
The zeros are x=1, x=-6
The exponential formula for this situtation will be given by:
f(x)=ae^(-bx)
where:
a=initial price
b=rate
x=time in years
hence the formula will be:
f(x)=28750e^(-0.12x)
thus the value of the car in 2018 will be:
x=2018-2012=6 years
thus
f(6)=28750e^(-0.12*6)
f(6)=$13,994.13
Answer:
5 seconds
Step-by-step explanation:
Looking at your function (h(t) = -16t^2 + 48t + 160), I see that the peak height will be 196 feet, and that is achieved in 1.5 seconds.
h(1.5) = -16(1.5)^2 + 48(1.5) + 160
h(1.5) = -16(2.25)+ 48(1.5) + 160
h(1.5) = -36 + 48(1.5) + 160
h(1.5) = -36 + 72 + 160
h(1.5) = 36 + 160
h(1.5) = 196
Going down from that height, it would take 3.5 more seconds, so it would take 5 seconds in total
h(5) = -16(5)^2 + 48(5) + 160
h(5) = -16(25) + 48(5) + 160
h(5) = -400 + 48(5) + 160
h(5) = -400 + 240 + 160
h(5) = -400 + 400
h(5) = 0
Answer: the one with the closed circle that is filled in and arrow pointing back
Step-by-step explanation:
if c is less than or equal to 7 it will be 7 and numbers less than 7 the closed circle that is filled in says that it will be less than 7 as well as 7
Answer:
64800
Step-by-step explanation:
you will multiply 60 by 18m to get how much you go in a minute. and then you multiply that by 60 again to get how much you go in an hour.
