Answer:
Max and Elena live 5764 miles away from each other.
Step-by-step explanation:
One mile is equivelant to 1.6 kilometers.
Let x and y be the two positive numbers. - Their product is 192: x * y = 192 equation 1
- the sum of the first plus twice the second is a minimum: x + 2y
<span>From the first equation, y = 192 / x.
Substitute that into the second equation:
</span>
x + 2y = x + 2(<span>192/x ) = x + 384/x
</span>f(x) is minimum when f'(x) = 0 and f"(x) > 0
f(x)= <span>x + 384/x
</span>
f(x) = 1-384/x^2
<span>1-384 / x^2 = 0
x^2-384 = 0
x^ 2= 354
x = radical 354 = 18.8 here i'm confused why the number is decimal

Answer:
28x=y
Step-by-step explanation:
28x=y because 14x-y=-14 plus y on both sides=
14x=-14y then add 14 to both sides=
28x=y

Answer:
D
Step-by-step explanation:
Using the rule of logarithms
log x - log y = log(
)
