Answer:All even number except 2 are composite numbers. 4 is the smallest composite number. step-by-step explanation:
2 dvd costs 28 therefore 1 dvd cost 14
and 5 dvd would b 5 times 14 so 70 dollars for 5 dvds
This is too big of a question for only 5 points
Answer:
Possible dimensions are 16 × 4 inches and 32 × 2 inches.
Step-by-step explanation:
We are given that,
Area of the frame = 64 inch² = Length × Width
Now, we have that 64 can be factored as,
64 = 32 × 2
64 = 16 × 4
64 = 8 × 8
Since, the frame is in a rectangular shape. So, we reject the possibility of 8 × 8 inches frame.
Thus, the possible dimensions are,
Set 1: 16 × 4 inches
Set 2: 32 × 2 inches.
The reduced form of the trig expression is 7/2sin²2a
<h3>Trigonometry identity</h3>
Trigonometry identities are written in terms of sine, cosine and tangent. Given the trigonometry identity
14sin² acos² a
Since sin(a)cos(a) = sin2a/2, hence
14sin²acos²a = 14[sin(a)cos(a)]²
14sin²acos²a = 14(sin2a/2)²
14sin²acos²a = 14/4(sin²2a)
14sin²acos²a = 7/2sin²2a
Hence the reduced form of the trig expression is 7/2sin²2a
