Answer:
B. 9 yards
Step-by-step explanation:
you just have to add the oak to pine and pine to end then you subtract the total of maple to end.
So for this, you'll be using an exponential equation, which is y=ab^x (a = initial value, b = growth/decay).
Since you start off paying your friend $1, that will be your initial value. And since this is a 50% increase, you are to add 1 and 0.5 together (50% in decimal form), which is 1.5. That will be your b variable. And since # of days is the independent variable, that will be your x variable.
Using the previous info, this is our equation: y = 1(1.5)^20 . From here we can solve for the total cost (y).
Firstly, solve 1.5^20: y = 1(3325.26)
Next, multiply everything on the right side of the equation, and your answer will be (rounded to the hundreths): y = 3325.26
In context, at the end of the 20 days, you have to pay your friend $3325.26.
Step-by-step explanation:
16⁴ - 2¹³ - 4⁵
= 2¹⁶ - 2¹³ - 2¹⁰
= 2¹⁰(2⁶ - 2³ - 1)
= 2¹⁰(64 - 8 - 1)
= 2¹⁰ * 55
= 2¹⁰ * 5 * 11.
Since it contains 11 in its prime factorization, it is divisible by 11. (Proven)
Number 2 is 990 because the numbers are 9, 10, and 11.
