Answer:
A
Step-by-step explanation:
Under a reflection in the x- axis
a point (x, y ) → (x, - y )
Under a rotation about the origin of 90°
a point (x, y ) → (- y, x )
Under a reflection in the y- axis
a point (x, y ) → (- x, y )
Under a rotation of 180°
a point (x, y ) → (- x. - y )
Here A(3, - 5 ) → A'(3, 5 ) → A
The number of words james can type in 6 minutes at the same rate is 360 words
Given:
Number of minutes to type 150 words = 2.5 minutes
let
number of words James can type in 6 minutes = x
Equate the ratio of the number of words to number of minutes
150 : 2.5 = x : 6
150/2.5 = x/6
cross product
150 × 6 = 2.5 × x
900 = 2.5x
x = 900/2.5
x = 360 words
Therefore, the number of words james can type in 6 minutes is 360 words

m=9
11-9m=-70
-11 -11
-9m = -81
divide both sides by -9 and you get m=9
Solution,
Radius(r)=6 cm
Height(h)=20 cm
Volume of cylinder= pi (r)^2 h
=3.14*(6)^2*20
=3.14*36*20
=2260.8 cm^3
