5cos2(x + 45) - 7
The period for cos = 2pi/k
The k = 2 so the period = pi
The phase shift is 45 degrees to the left.
So for 12.5 meters...the little guy walks 5 meters per minute....
<span><span><span>12.5meters</span><span>5<span><span>meters</span><span>minute</span></span></span></span>=2.5minutes</span>
we can check it by saying...okay...if his speed was 5 meters per minute....and he walked for 2.5 minutes...does he walk 12.5 meters?
<span>5×2.5=12.5</span><span>
so yes it checks out :)</span>
Answer:
1/250 W/m² or 0.004 W/m² or 4 mW/m²
Step-by-step explanation:
The cargo worker is (50 m)/(1 m) = 50 times the reference distance. The intensity varies as the inverse of the square of the distance, so will be ...
(1/50)²×(10 W/m²) = 10/2500 W/m² = 1/250 W/m²
This might be more conveniently written as 4 mW/m².
Answer:
6 to the power of 2.
Step-by-step explanation:
Recall that whenever you divide exponents with the same base, you subtract the powers, but the base will still be the same. Therefore, 6 to the power of 12 divided by 6 to the power of 10 is 6 to the power of 2. Subtract the powers (exponents) or 12 minus 10, and you get 2. Since the base doesn't change, it is still 6. The solution to this expression is 6 to the power of 2. Hope this helps!
