1) 270 Fahrenheit
2) 34 Minutes
3) 48 Seconds
To find the probability simply divide the number of blue marbles by the total:
SO, 3 / 7 = 0.42857
p = 0.429
Sin 2 x + sin x = 0
( sin 2 x = 2 sin x cos x )
2 sin x cos x + sin x = 0
sin x ( 2 cos x + 1 ) = 0
sin x = 0
x 1 = 0
x 2 = π
or: 2 cos x + 1 = 0
2 cos x = - 1
cos x = -1/2
x 3 = 2π/3
x 4 = 4π/3
Answer:
x = -5
y = 0
Step-by-step explanation:
x-y = -5 -----eqn 1
x-y = 1/3 ------eqn 2
From eqn 1
x-y = -5
x = -5 + y -----eqn 3
From eqn 1
-5+y-y = -5
y = 0
Eqn 3
x = -5 + 0
x = -5
Answer:
-(x + 5)(3x + 1)
Step-by-step explanation:
Step 1: Factor out negative
-1(3x² + 16x + 5)
Step 2: Factor quadratic
-(x + 5)(3x + 1)
