Answer:
b
Step-by-step explanation:
Part A.
1) Function given:

2) Interpretation:
initial value: => x = 0 => f(x) = 0.69
table:
x f(x)
year price
0 0.69
1 0.69 * 1.03 = 0.7107 => increase = 3%
2 0.69 * (1.03)^2 = 0.732021 => increase = 3%
So,
the answer is that the function is increasing at 3% per year.Part B.
3) table
<span> t (number of years) 1 2 3 4
f(t) (price in dollars) 10,100 10,201 10,303.01 10,406.04
Percent change:
Year 2: 10,201 / 10,100 = 1.01 => 1% increase
Year 3: 10,303.01 / 10,201 = 1.01 => 1% increase
Year 4: 10,406.04 / 10,303.01 = 1.01 => 1% increase.
Answer: the </span><span>
product of the part A recorded a greater percentage change in price over the previous year (3% vs 1%).</span>
Answer:
165
Step-by-step explanation:
formula is
nCr = n!/(r!(n−r)!)
r= 8 = number of choosing objects from the set
n = 11 = total number of objects in the set
C(n,r)=C(11,8)
=11!/(8!(11−8)!)
! means factorial
factorial means to multiply by decreasing positive numbers.
For example, 8! = 8 ∗ 7 ∗ 6 ∗ 5 ∗ 4 ∗ 3 ∗ 2 ∗ 1 = 40320
=11!/8!×3!
= 165

Answer:
a. sin 30* = sin 150*
b. sin 1* = sin 179*
a. cos 340* = cos 20*
b. cos 260* = cos 100*
Step-by-step explanation:
sine is symmetrical around x = 90*
cosine is symmetrical around x = 180*
* means degree sign of course.
Answer:
4x = y
Step-by-step explanation:
If y is 36 and x is 9, you know 9 x 4 = 36. So it would be 4x = y
