The width of the rectangle is 11.5
12inches because 3 is pi and 2 is Radius so 3x2squared=12
Angle A is 150
Angle B is 30
Supplementary= 180, so....
Angle A + Angle B = 180
150 + 30= 180
hope this helps
First you must know that is i∧2= -1
x∧3-4x∧2+4x-16 = x∧2 (x-4) + 4 (x-4) = (x-4) (x∧2+4) = (x-4) (x∧2-(-4)) =
= (x-4) (x∧2-(-1) *4) = (x-4) (x∧2- i∧2*2∧2) = (x-4) (x∧2-(2i)∧2) = (x-4) (x-2i) (x+2i)
Good luck!!!
Answer:
200 litres
Step-by-step explanation:
let g be gasoline used, d the distance travelled and s the speed, then the equation relating the quantities is
g = kd
← k is the constant of variation
To find k use g = 25, d = 100 and s = 100, then
25 = k × 100 ×
= k × 100 × 10 = 1000k ( divide both sides by 1000 )
0.025 = k
g = 0.025d
← equation of variation
When d = 1000 and s = 64, then
g = 0.025 × 1000 ×
= 0.025 × 1000 × 8 = 200
