Answer: multiply 8 on all x number of books read
Step-by-step explanation:
1 is 8 because 8 × 1 is 8
2 is 16 because 8 × 2 is 16
3 is 24 because 8 × 3 is 24
4 is 32 because 8 × 4 is 32
5 is 40 because 8 × 5 is 40
6 is 48 because 8 × 6 is 48
7 is 56 because 8 × 7 is 56
8 is 64 because 8 × 8 is 64
9 is 72 because 8 × 9 is 72
10 is 80 because 8 × 10 is 80
The answer is C) 14 years.
Plug it in to check:
12500(1+0.0525)^14
12500(2.05) = 25,587.01 (rounded to 25000)
Answer:
14. congruent means "THE SAME" so it will be "A" because there all the same letter.
15. D
By <span>(x + 5/x^2 + 9x + 20) you apparently meant the following:
x+5
----------------------
x^2 + 9x + 20
and by
</span><span>(x^2-16/x-4)
x^2-16
you apparently meant ---------------
x - 4
Please use additional parentheses for clarity.
Dividing,
</span> x+5 (x-4)(x+4)
---------------------- * ---------------
x^2 + 9x + 20 x-4
Now, x^2 + 9x + 20 factors into (x+4)(x+5), so what we have now is
(x+5)(x+4)
------------------------- = 1 This is true for all x, so there are no exclusions.
(x+4)(x+5)
Answer:
Option (3)
Step-by-step explanation:
By applying cosine rule in the triangle ABC,
BC² = AC² + AB² - 2(AC)(AB)cosA
5² = 3² + 7²- 2(3)(7)cosA
25 = 9 + 49 - 42cos(A)
25 = 58 - 42cos(A)
cos(A) =
A =
A = 38.21°
A ≈ 38°
Option (3) will be the correct option.
