Answer is B. 48
By circle theorem, the angle at the centre of the circle is twice the angle at the circumference.
The unit numbers can be 2,4,6.Suppose 2 as the unit number we can form 20 numbers the same way for 4 and 6 so totally 60 numbers.
Answer:
Step-by-step explanation:
f(x) = (1/2) *6^x = 2^-1 * 2^x *3^x
y= 2^ (x-1) * 3^x
Domain represents all values that x can have and is all real numbers
Range all values that y can have and is y > 0 ( all real numbers that are positive)
The y-intercept is the point where the graph intersects the y-axis so x=0 there
y = 2^(0-1) *3^0 = 1/2 *1 = 1/2
the asymptote is at y= 0
Well let's see what floor each one lands on and figure out which one is higher.
Something to note:
down = subtracting
up = adding
if something says it's doing something more than once, add it the number of times it's doing that thing. (You can also multiply it by that number but the adding way is a bit easier to understand and explain)
<u>Elevator 1:</u>
6 + 7 + 7 - 10 = 10
<u>Elevator 2:</u>
20 - 5 - 5 - 5 + 12 = 17
Elevator 2 ends on a higher floor (reasoning above)
