Step-by-step explanation:
Well Roberts can’t have a negative income and due to the number of violins being whole numbers, it is impossible to have 2.273 violins.

Answer:
y = - 5
Step-by-step explanation:
y = 4 is a horizontal line parallel to the x- axis
A parallel line must therefore be a horizontal line with equation
y = c
where c is the value of the y- coordinates the line passes through.
The line passes through (1, - 5) with y- coordinate - 5, thus
y = - 5 ← equation of parallel line
So the question if find y'' for 4y=cos2x
First, find y by dividing by 4. y = cos2x/4
Then, take the first derivative. y' = -sin2x/2
Then, take the second dervative. y'' = -cos2x
Answer:
180° is galf a full turn, so it takes 1/2 less time that is 20 seconds
90° is 1/4 of a full turm (360°), so it will take (1,4)×40= 10 seconds
45° is 1/8 of 360, so it will take 5 seconds
270° IS 3/4 pf 360°, so the answer is (3/4)×40 = 30 seconds
