Y=e^-0.3t would better be written as y<span>=e^(-0.3t), because you want to emphasize that the exponent of "e" is -0.3t. Enclose the expon. within ( ), ps.
Since the expo is neg, this is expo. decay, and the rate is 0.3 per time period.
For example, if y is = to .5 right now, the next value, after 1 time period, will be
.5(.3) = .15.</span>
Answer:
Then, the area is 222,48 in
Step-by-step explanation:
The area of the regular polygon is: 1/2 x perimeter x apothem.
The perimeter 6 times the number of sides of the polygon which is 9*6in = 54 in.
The apothem is: s/2tan(180/n) where "s" is the lenght of the side and "n" the number of sides.
apothem = s/2tan(180/n) = 6in/(2tan(180/9)) = 8.24 in
Then, the area is: 1/2 x 54 in x 8.24 in = 222,48 in
Step-by-step explanation:
14=2(w-14)
7=w-14
w=21
Answer:
Yamal can move the ice to 82 km in approximately <u>15 hrs</u>.
Step-by-step explanation:
Given:
Speed = 5.5 km/hr
Distance = 82 km
Let time be represented as 'x'.
We need to find the number of hours required to travel 82 km.
We know that Distance can be calculated by the product of Speed and time.
Framing above sentence in equation form we get;
Distance = Speed × Time
Substituting the given value we get;

Hence The expression for number of hours is 
Solving the equation to find the value of x we get;

Hence Yamal can move the ice to 82 km in approximately <u>15 hrs</u>.
