Answer:
.35 kilometers
Step-by-step explanation:
x^2 = -169
there is no real solution to this problem
Answer:
A≈118.2
Step-by-step explanation:
r= Radius= 3.5
l= Slant height= 7.25
A= πrl+πr2= π·3.5·7.25+π·3.52≈118.20242
Answer: y=-0.6x^3- 1
Step-by-step explanation:
In the graph, first we must see the points where the line intersects the axis.
We can see that it goes throug the point (0, -1)
Now, of the given options the only two that are 0 when x is -1, are:
f1(x) =y = 0.6*x^2 - 1
f2(x) =y = -0.6x^3 - 1
We also can see that for all the positive values of x, y has a negative value, so let's value bot functions in x = 2, and see what happens.
f1(2) = 0.6*4 - 1 = 1.4
f2(2) = -0.6*8 - 1 = -5.8
so the correct option is
y=-0.6x^3- 1
