14 For which equation is the solution set {-5,2}?. 15 Which equation has the same solutions as. 2x. 2 + x - 3 = 0.
Just do circumference over pi (this'll give you the diameter) and then divide by 2 to get radius like so:
44/pi=14.0056349921/2=7.0028175 is your answer
îdk how you wanna round but nearest hundredth would be 7.00 cm while nearest tenth would be 7.0 cm and nearest whole number would be 7 cm
Answer:
1 + cosa sina
Step-by-step explanation:
cos³a - sin³a ← is a difference of cubes and factors in general as
a³ - b³ = (a - b)(a² + ab + b²) , then
cos³a - sin³a
= (cosa - sina )(cos²a + cosa sina + sin²a)
= (cosa - sina)(1 + cosa sina) [ sin²a + cos²a = 1 ]
Then
= 
← cancel (cosa - sina) on numerator/ denominator
= 1 + cosa sina
