Evaluate the trigonometric expression using sum and difference formulas.
<u>Answer</u>
C. 4 + 6
D. 3.15151515.. + 4.6
E. √64 × √25
<u>Explanation</u>
A rational number is a number that can be expressed as a quotient or a fraction. That is it can be written as a/b.
π×6 = 6π ⇒ can not be written as a rational number.
√3 + √5 ⇒ the sum of two irrational numbers can not be rational.
4 + 6 = 10. Ten is a rational number. it can be written as 10/1
3.15151515.. + 4.6 = 104/33 + 23/5
= 1279/165
√64 × √25 = 8×5=40 This can be written as 40/1
Answer:
Step-by-step explanation:
New height to initial height=
10/4=2.5
New width from initial width should be 5×2.5=12.5inches
If the signs of the rational numbers are the same, you add them, i.e. ++ or --.
If they are different, you subtract them, i.e. +- or -+
If
is the number of members under 25, then we have
