Answer:
(4) 0
Step-by-step explanation:
<u>Given:</u>
cos²27°×cos²34°×...×cos²167 = ? <u>Looking at the angles measures, they form series of: </u>
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>
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

Answer:
true
Step-by-step explanation:
The giving functions are from dofferent types. transforming a function does not change it's type so it is impossible to transfer f(x)=2 to f(x)=(x-3)^2-1.
The work has one step: divide the expression by 3.
.. -4 > x
Because the symbol is "greater than", the circle at x=-4 is an open circle.
