Answer:
B
Step-by-step explanation:
divide 4 and 12 by 4 and get 1/3
Answer:
<em>75.408 ft</em>
Step-by-step explanation:
In 20 minutes, the angle swept by a minute hand is calculated as
(20/60) x 360° = 120°
The length of the minute hand = 36 ft
To calculate the distance moved by the minute hand, we solve for the fraction of the circumference of a circle swept by the minute hand in going through this 20 min.
we use the expression
Distance moved by the tip of the minute hand d = (θ/360) x 2πR
where
θ is the angle swept in the 20 minutes = 120°
R is the length of the minute hand, which is the radius of the circle formed if the minute hand moves completely in a 360° motion round the clock.
R = 36 ft
substituting values, we have
d = (120/360) x (2 x 3.142 x 36) = <em>75.408 ft</em>
Z = 13/x
sub Z inside YZ = 4
Y(13/x) = 4
13Y * YX = 4
YX = 4/13Y
(3x2 + 7y) (2x2 – 3x + 9)
=(6+7y)(-3x+13)
=-18x+78-21xy+91y
Answer:
Option 4
Step-by-step explanation:
Given:
Sinθ = 
Since, cos2θ = 1 - 2sin²θ
cos2θ = 
cos2θ = 1 - 
cos2θ = 
cos2θ = 
Therefore, Option 4 will be the answer.
