1/3 you simplify 3/18 to 1/6 then it then goes onto 1/3

second question:
January: 32 · 22 + 38 · 18 = 704 + 684 = 1388
December: 18 · 22 + 40 · 18 = 396 + 720 = 1116
1388 - 1116 = 272
Answer: $272.
Answer:
Step-by-step explanation:
For compound interest, we use the formula A = P(1 + r/n)^{nt}, where A is the amount, P is the principle, r is the rate, n is the number of times compounded per period of time, and t is the time.
We can alter this for a decrease. Instead of adding r/n to 1, we can substract it:
A = 17,600 * (1 - 0.01175 / 1)^{1 * 11} = 15,454.24
After 11 years, the car will be worth $15,454.24
Answer:
29
Step-by-step explanation:
it's arithmetic sequence.
it has a basic equation like this
Un = a + (n-1)d
a = U1 = first number in sequence
Un = number in n-th term
d = difference
U9 = 101 + (9-1)(-9)
U9 = 101 - 72
U9 = 29
so the 9th term is 29
Answer:
23. 16x² + 4x + 0.25
24. 16x² - 4x + 0.25
Step-by-step explanation:
Given the functions f(x) = 4x + 0.5 and g(x) = 4x - 0.5, questions 23 and 24 are asking you to square the entire function. So, you will take the expression given in each function and square it:
(f(x))² = (4x + 0.5)(4x + 0.5) Using FOIL:
(4x*4x) + (4x*0.5) + (4x*0.5) + (0.5*0.5)
16x² + 2x + 2x + 0.25 = 16x² + 4x + 0.25
(g(x))² = (4x - 0.5)(4x - 0.5) Using FOIL:
(4x*4x) - (4x*0.5) - (4x*0.5) + (0.5*0.5)
16x² - 2x - 2x + 0.25 = 16x² - 4x + 0.25
