Let
x = number of months
y = number of sunny days.
We write the equation that represents the problem as:
y = 16x
Example: number of sunny days for 2 months:
y = 16 * (2) = 32 days
Answer
an expression to represent the approximate number of sunny days for any number of months is
y = 16x
Yes it is an exponential function as the value of y increases exponentially as x increases.
Answer:
x = 16
Step-by-step explanation:
vertical angles are equal
3x = 2x+16
x = 16
Answer:
42
Step-by-step explanation:
The permutation formula is P(n, r) = n! / (n - r)!. We know that n = 7 and r = 2 so we can write:
7! / (7 - 2)!
= 7! / 5!
= 7 * 6 * 5 * 4 * 3 * 2 * 1 / 5 * 4 * 3 * 2 * 1
= 7 * 6 (5 * 4 * 3 * 2 * 1 cancels out)
= 42
