If a and b are positive numbers, find the maximum value of f(x) = xa(7 â x)b on the interval 0 â¤ x â¤ 7.

algol [13]

Given $f(x)=x^a(7-x)^b$ on the interval 0 ≤ x ≤ 7, for maximum value, f'(x) = 0.

$f'(x)=0 \\ \\ \Rightarrow -bx^{a}(7-x)^{b-1}+ax^{a-1}(7-x)^b=0 \\ \\ \Rightarrow ax^{a-1}(7-x)^b=bx^{a}(7-x)^{b-1} \\ \\ \Rightarrow a(7-x)=bx \\ \\ \Rightarrow (a+b)x=7a \\ \\ \Rightarrow x= \frac{7a}{a+b}$

13. Find the values of x and y in the diagram below.

Umnica [9.8K]

Answer:

x = 2

y = 4

Step-by-step explanation:

Let's start with the 7 in the middle. Subtract the 1 on its upper left to get 6.

Add the 3 on its lower left to get 10.

so, 3 - x = 1. x = 2

17 - y = 13. y = 4

Colt1911 [192]

Question:

Write an algebraic expression for how many miles Mr.Stein drove.

Answer:

(70 - y) miles

Step-by-step explanation:

Given

Distance to business meeting from office = 70 miles

Mr. Smith drove the first y miles

Let x = the remains distance driven by Mr. Stein

x + y = 70 ---- Make x the subject of formula

x = 70 - y

So, the expression is (70 - y) miles
