Answer:
120 miles in 2 hours
Step-by-step explanation:
120 because half of a tank is 60 miles so a whole tank means double half, which gives 120 and you also double the hour to 2 hours.
Answer:
The value of x is 13.5 units.
Step-by-step explanation:
You can also apply this formula :
So for this question :
g(x)= 3k-2x²
g(-3)=-6 ____(1)
So, using (1),
-6 = g(-3)
=> -6 = 3k - 2(-3)²
=> -6 = 3k - 2(9)
=> -6 = 3k - 18
=> -6 +18 = 3k
=> 12 = 3k
=> 12/3 = k
=> 4 = k
Now, you can find g(n) for any number n, as now we know the value of k. Specify the value of x, if you want to know what is g(x).
Answer:
option 1
Step-by-step explanation:
formula:(x-h)^(2)*(y-k)^(2)=r^2
well if you move the circle 3 units left h is (-3), plug it in, you get 3, so it is (x+3)^2*(y-k)^(2)=r^2
if you move the circle 2 units up, plug it in you get (-2), so it is
(x+3)^2*(y-2)^(2)=r^2
now, the radius is 3 (we can see from the graph) so radius ^2 is 9, thus
(x+3)^2*(y-2)^(2)=9
this is the answer, and the option that has it is answer is option 1
h(x) = f(x) + g(x)
= 600 (1.14)^x + 450(1.14)^x
1050 1.14^x
Choice A
