The two non negative real numbers with a sum of 64 that have the largest possible product are; 32 and 32.
<h3>How do we solve the nonnegative real numbers?</h3>
Let the two numbers be x and y.
Thus, if their sum is 64, then we have;
x + y = 64
y = 64 - x
Their product will be;
P = xy
Putting (64 - x) for y in the product equation we have;
P = (64 - x)x
P = 64x - x²
Since the product is maximum, let us find the derivative;
P'(x) = 64 - 2x
At P'(x) = 0, we have;
64 - 2x = 0
2x = 64
x = 64/2
x = 32
Thus; y = 64 - 32
y = 32

Answer:
C. 70 mi
Step-by-step explanation:
42+56= 98
98 is the distance is from Ferris to Dunlap to Buttle.
To find the distance directly from Ferris to Buttle, you have to use a^2+b^2=C^2.
42^2+56^2=c^2
1,764+3,136=c^2
√4,900=√c^2
70=c
