Express the product of cos 30°and 45° in simple simplest radical form

Answers

Answer 1

Answer: $cos30^0= ( √(3) )/(2) \ \ \ and\ \ \ cos45^0= ( √(2) )/(2)\n\ncos30^0\cdot cos45^0= ( √(3) )/(2)\cdot ( √(2) )/(2)= ( √(3) \cdot √(2) )/(2\cdot 2)=( √(6) )/(4)$

Answer 2

Answer: This means the multiplication of the cos of the particular angles

$cos(30^(o)) = ( √(3) )/(2) , cos(45^(o)) = ( √(2) )/(2)$

So, multiplying them together is

$= ( √(3) )/(2) *( √(2) )/(2) = ( √(6) )/(4)$

You can draw a quadrilateral with no parallel lines and at least one right angle.TRUE OR FALSE

Answers

The answer is true. All you need is one 90 degree angle, two 50 degree angles, and one 170 degree angle. This creates a weird looking shape that is a quadrilateral with no parallel lines and at least one right angle.

The manager of a public pool is counting the people who came to swim in June and July. There were 600 people who came in June. There were 800 people who came in July. What is the percent increase in people who came from June to July?25%

200%

3313%

75%

Answers

So,

The percent increase is basically the same as percent decrease except that you subtract the June count from the July count. If you let x be the June count and y be the July count, you can write it mathematically as follows:
$(y -x)/(x) = percent\ increase$

Substitute.
$(800 - 600)/(600) = percent\ increase$
$(200)/(600) \ or\ (1)/(3) = percent\ increase$

The percent increase in people from June to July is 33.3333333%, which is not one of the options you put there.
