Consider the given function and the given interval.
docker41 [41]

Answer:

  (a)  fave = 8

  (b)  c = 64/9

  (c)   c ≈ 7.111

Step-by-step explanation:

(a) The average value of the function is its integral over the interval, divided by the width of the interval.

  f_{ave}=\displaystyle\frac{1}{16-0}\int_0^{16} {3x^{\frac{1}{2}}} \, dx=\left.\frac{x^{3/2}}{8}\right|_0^{16}=8

__

(b) We want ...

  f(c) = 8

  3√c = 8 . . . . . use f(c)

  √c = 8/3 . . . . . divide by 3

  c = (8/3)² . . . . square

  c = 64/9

__

(c) c ≈ 7.111

What is the perimeter of the triangle (4,1) (2,5) (1,-1)
Naya [18.7K]

the perimeter of the triangle=14.38

The coordinates of the triangle (4,1),(2,5),(1,-1);

In geometry, the perimeter of a shape is defined as the total length of its boundary.

The perimeter of the triangle is the sum of all the sides of the triangle =a+b+c (assuming a,b, and c are the sides of the triangle)

By using the distances formula find the length of the sides of the triangle:√[(x₂ - x₁)² + (y₂ - y₁)²],

where (x₁,y₁),(x₂,y₂) are the coordinates ,

a=√[(4 - 2)² + (1- 5)²] = \sqrt 20=4.7

b=√[(2 -1)² + (5 -(-1))²]=\sqrt37=6.08

c=√[(1 -4)² + ((-1)-1)²]=\sqrt13=3.60

the perimeter of the triangle=a+b+c=4.7+6.08+3.60=14.38

hence ,perimeter of the triangle=14.38

find an expression that represents the difference when (3x+6y)(3x+6y) is subtracted from (4x+9y)(4x+9y) in simplest terms. what
love history [14]

The difference between (3x+6y)(3x+6y) and  (4x+9y)(4x+9y) is 7x² +36xy+45y²

<h3>What is an Expression ?</h3>

An expression is a mathematical statement which has variables , constants and mathematical operators  simultaneously.

The expression given in the question is

(3x+6y)(3x+6y) and  (4x+9y)(4x+9y)

the difference when (3x+6y)(3x+6y) is subtracted from (4x+9y)(4x+9y)

(4x+9y)(4x+9y) -  (3x+6y)(3x+6y)

16 x² + 36xy+36xy +81y²-9x²-18x -18x -36y²

7x² +36xy+45y²

Therefore in simplest term , The difference between (3x+6y)(3x+6y) and  (4x+9y)(4x+9y) is 7x² +36xy+45y²
