The one is in the cents place, so we cannot round because there are no more digits
Answer:
associative property of multiplication
Step-by-step explanation:
Associative property of multiplication states that (a x b) x c = a x (b x c).
5 * (sqrt(9) *4) = (5* sqrt(9) ) *4
Answer:
Multiply 15 by 9, then divide by 2.
Step-by-step explanation:
We need to solve the given expression.
We know that,
We have,
a = 15, b = 2 and c = 9
So,
So, the steps are "Multiply 15 by 9, then divide by 2".
Answer:
The value of SecФ is .
Step-by-step explanation:
Given as for trigonometric function :
tan²Ф =
Or, tanФ =
∵ tanФ =
So, =
So, Hypotenuse² = perpendicular² + base²
or, Hypotenuse² = ( )² + ( )²
Or, Hypotenuse² = 3 + 8 = 11
Or, Hypotenuse = ( )
Now SecФ =
or, SecФ = =
<u>Second Method</u>
Sec²Ф - tan²Ф = 1
Or, Sec²Ф = 1 + tan²Ф
or, Sec²Ф = 1 +
Or, Sec²Ф =
Or, SecФ =
Hence The value of SecФ is . Answer
