Find two numbers whose difference is 154 and whose product is a minimum.

1 answer:

7 0

Y - x = 154
let z = xy = x(154 + x) = x^2 + 154x

we need to find the minimum value of z

z' = 2x + 154 which = zero for minm or maxm value

x = -77 and y = 154 -77 = 77

so the 2 numbers are -77 and 77

Answer:

$f(a) = 3a + 1 \\ Now,\: a = - 1 \\ f( - 1) = 3( - 1) + 1 \\ f( - 1) = - 3 + 1 \\ \boxed{ f( - 1) = - 2}$

Therefore, -2 is the right answer.

Answer:

y'= 5x^4 + 5^x In(5)

Step-by-step explanation:

Differentiate with Respect to x

f(x)'=5x^4 + In(5^x)

f(x)'= 5x^4 + x In(5)

with respect to x, we have

y'= 5x^4 + y In(5)

y'= 5x^4 + 5^x In(5)

Hunter-Best [27]

Answer:

Tom will need $\dfrac{5}{4}$ gallons of fruit drink.

Step-by-step explanation:

Hint- This question can be solved by unitary method.

Tom has a recipe for punch that calls for $\dfrac{1}{2}$ gallon of fruit drink.

i.e for 1 batch of the punch Tom needs $\dfrac{1}{2}$ gallon of fruit drink.

For $\dfrac{5}{2}$ batch of the punch Tom needs $\dfrac{1}{2}\times \dfrac{5}{2}=\dfrac{5}{4}$ gallons of fruit drink.

Therefore, Tom will need $\dfrac{5}{4}$ gallons of fruit drink.
