Please solve this problem ​
asambeis [7]

Answer:

(4) 0

Step-by-step explanation:

<u>Given:</u>

  • cos²27°×cos²34°×...×cos²167 = ?

<u>Looking at the angles measures, they form series of: </u>

  • 27, 34, 41, ..., 167

This is AP with the first term of 27 and common difference of 7

<u>We can see one of the terms of this AP is 90</u>

  • 27+9*7 = 27 + 63 = 90

Since cos 90° = 0 ⇒ cos²90° = 0 and therefore given series equals to zero as one of the terms of multiplication is zero.

<u>So correct answer choice is</u>  Option 4) 0

Mrs Bean bought a business at the start of 2006
Luden [163]

A = P(1+\frac{r}{n} )^{nt} \\P = 30000\\r = .02\\n = 1 time a year\\t = 2018 - 2006\\\\A = 30000(1 + .02/1)^{1*12} \\A = \$ 38047.25\\----------------\\Solve for 'r'\\95000 = 8000(1 + r/1)^{1*5} \\95000 = 8000(1+r)^{5} \\11.875 = (1 + r)^{5}\\1.64031 = 1+r\\

I see I did something wrong in the 2nd part, just take the first question as the right one.
