Converting from one units to another set of units, a conversion factor is needed. For this problem, the conversion factor would be 1 mile = 1610 m. We convert the value of <span>speed</span> of light from meters/second to miles/hour as follows:
3 x 10^8 m/s (1 mile / 1610 m) ( 60 s / 1 min ) ( 60 min / 1 hr ) = 6.71 x 10^8 miles / hr
Answer:
1/8, 1/12, 1/24, 1/100, and so on there are a lot
Step-by-step explanation:
Answer:
p=-1
Step-by-step explanation:
11p+16=2p+7
-2 -2
9p+16=7
-16 -16
9p=-9
9/-9
p=-1
this is for the Sin
*Remember that sin = opposite / hypotenuse*
a² + b² = c² (where a and b are legs and c is the hypotenuse)
From the picture, you can see:
a = 3
c = 4
Plug these into the equation and solve for b.
* a² + b² = c² *
step 1: 3² + b² = 4²
step 2: 9 + b² = 16
step 3: b² = 16 - 9
step 4: b² = 7
step 5: √(b²) = √7
step 6: b = ± √7
FOR COS:
From the picture, you can see that if θ is in quadrant II, b has to be negative.
b = -√7 = adjacent
Remember that cos θ = adjacent / hypotenuse.
cos θ = adjacent / hypotenuse
cos θ = (-√7 / 4)
