Answer:
Suppose that the equations are:
The number of people increases exponentially as the temperature increases, so we can write this as a simple exponential relation.
N(T) = a0*r^(T)
Also, the number of people that leaves the park as the temperature increases are:
M(T) = a*T + b
So the combination of these equations can say the number of people that are arriving to the park minus the number of people that are leaving, this would be:
N(T) - M(T) = total change in the park population as the temperature changes = C(T)
C(T) = a0*r^(T) - a*T - b
4x²=16
x²=16/4
x²=4
√(x²)=+/-√4
x(1) =2, x(2)=-2
Answer:
22.6°
Step-by-step explanation:
Since all three sides of the right triangle are given, you can use any of the trig ratios to find the angle. I choose to use the tangent.
tan(A) = BC/AC = 5/12
Then the inverse trig function tells you ...
A = arctan(5/12) = 22.6°
Answer:
Julie can buy 9 gift cards and will have 79 reward points left over
Step-by-step explanation:
If you divide 1,429 by 150, the number before the decimal, 9, is how many she can buy without exceeding her limit
Then, multiply 9 and 150 to see how many points 9 gift cards is worth (1350)
Subtract 1429-1350 to find the leftover points (79)
That is the simplified fraction
