Answer:
4
Step-by-step explanation:
Written in standard form, the quadratic is ...
x^2 -2x -3 = 0
This can be factored as ...
(x -3)(x +1) = 0
so the solutions are ...
x = 3, x = -1 . . . . . . values of x that make the factors zero
The difference of interest is ...
3 -(-1) = 4
Answer:
the time is 1.57 sec and the distance is 49.32mm
Step-by-step explanation:
Given that,
The angle is 180°
Angular velocity is 2rev/sec
The radius is 10mm
we are to find the time and distance traveled at that time
The formula is
θ = at
where t is the time,
a is the angular velocity
θ is angle in radian
so,
θ = 180° × π/180°
θ = π
= 3.14
Hence ,
θ = at
3.14 = 2t
t = 1.57sec
let the distance be xmm

Therefore , the time is 1.57 sec and the distance is 49.32mm

Answer:
13.8
Step-by-step explanation:
tan Q = <u>opposite </u> = <u>40</u>
adjacent x
Tan 71 = <u>40</u> x tan 71 = 40
<u> x tan 71</u> = <u> 40 </u>
tan 71 tan 71
x = <u> 40 </u> = 13.7731 = 13.8 (rounded to the nearest tenth)
tan 71
