After 5 s, the particle traverses a path subtended by an angle of
(3π/4 rad/s) (5 s) = 15π/4 rad
Now, 15π/4 rad = 15/8 * 2π rad, so the arc has a length equal to 15/8 of the circumference of the path:
15/8 * 2π * (3 cm) = 45π/4 cm ≈ 35.3 cm
Range = 6.9
mode = 4.2
median= 3
Answer:
Step-by-step explanation:
Sin x = opp/hyp
Sin x = 4/7
Sin x = 0.5714
X =sin-¹(0.5714)
X = 34.8
X = 35°
you have to either divide add subtract multiply
Answer:
x = -4 (multiplicity 2)
Step-by-step explanation:
x^2 + 8x + 16 = 0
You need 2 numbers whose product is + 16 and whose sum is +8.
They are +4 and + 4 so the factors are:-
(x + 4)(x + 4)
(x + 4)(x + 4) = 0
x = -4 (multiplicity 2)
(There are 2 zeroes each of value -4)
