Answer: 180
Step-by-step explanation: 36 times 5 is 180
Answer:
Step-by-step explanation:
1) f(x) = 7 - 8x²
f(3) = 7 - 8*3²
= 7 - 8*9
= 7 - 72
f(3) = -65
2) f(a) = -5(a-2)
f(3) = -5(3 -2) = -5 * 1 = -5
4) f(m) = m(m +4)
f(3) = 3*(3+4) = 3 * 7 = 21
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.
Expanded form is like this 300 plus 20 plus 7 plus .40 plus .6
Answer:
X = 100
Y= 140
Step-by-step explanation:
The angle of y is same with 140, x u just need to 180= 2(180-140)+x
