Answer: below(=
Step-by-step explanation: Given that,
dimensions of wall = 8.3ft by 7.5ft
height of wall = 8.3
width of wall = 7.5
there are total 3 walls in a bedroom to be painted blue.
Formula to calculate area of one wall
Height x Width
Formula to calculate area of four walls
3 (Height x Width)
= 3( 8.3ft x 7.5ft)
= 3 (62.25 ft²)
= 186.75 ft²
So area Alyssa will paint = 186.75 ft²
Answer:
D
Step-by-step explanation:
For roots r1 and r2, the factors are (x-r1)(x-r2)
given
r1 and r2 arer 5+i√2 and 5-i√2
(x-(5+i√2))(x-(5-i√2))=
(x-5-i√2)(x-5+i√2)=
remember that i²=-1
x²-10x+27
make y the subject
y= 5x + 3
perpendicular line needs the reciprocal of the gradient
y = 1/5x + c
substitute in the point
1 = 1/5(5) + c
5/5 = 1 so the answer is y = 1/5x
hope this is helpful!
