Answer:

Ans: 0.766

Step-by-step explanation:

Use the trig identity: cos (a + b) = cos a,cos b - sin a.sin b

cos (25 + 15) = cos (40) = cos 25.cos 15 - sin 25.sin 15.

The arc

40

∘

doesn't have exact functional value.

You may get its approx. value by calculator.

cos 40 = 0,766

What two whole numbers is 29−−√ between?: 3 and 4 4 and 5 5 and 6 6 and 7
jolli1 [7]

The two whole numbers are 5 and 6 ⇒ 3rd answer

Step-by-step explanation:

To prove that a square root number lies between which two consecutive integers do that

  • Find a square number less than the number under the root
  • Find a square number greater than the number under the root
  • Find the square root of the square numbers, they will be the two integers that the root lies between them

∵ The number is \sqrt{29}

- Find a square number less than 29

∵ 25 is a square number

∵ 25 is less than 29

- Find a square number greater than 29

∵ 36 is a square number

∵ 36 is greater than 29

∴ 25 < 29 < 36

- Take √ for each number

∴ \sqrt{25} < \sqrt{29} < \sqrt{36}

∵ \sqrt{25}  = 5

∵ \sqrt{36}  = 6

∴ 5 <  \sqrt{29}  < 6

The two whole numbers are 5 and 6
