Answer:

  1. 4√3 ≈ 6.92820
  2. 10

Step-by-step explanation:

1. The integral from 0 to 3 of 2x^(1/2) can be found using the power rule:

  area = 2(2/3x^(3/2)) for x = 3

  = 4/3(3√3)

  area = 4√3 . . . square units

__

2. The line equation for y=0 is corrupted, so we assume the line equation for x is intended to be x=0. The area is a right triangle with side lengths 4 and 5, so the geometric area formula applies:

  A = 1/2bh = 1/2(4)(5) = 10

The area of the triangular region is 10 square units.

_____

<em>Additional comment</em>

If you really intend the right bound of the enclosed area to be x=b, then the area is the shape of a trapezoid. One base length is 5; the other is (5 -5/4b), and the height of the trapezoid is (b). The area is then ...

  A = 1/2(b1+b2)h

  A = 1/2(5 +5 -5/4b)(b) = 5b -5/8b^2

A positive integer is 10 less than another. If the sum of the reciprocal of the smaller and twice the reciprocal of the larger i
stira [4]

The two integers are are mathematically given as

x=3.70

y=13.7

<h3>What is  the two integers?</h3>

Generally, the equation for the two integers is mathematically given as

x + 10 = y

1/x + 2/y = 2/3

Substitute

1/x + 2/x+10 = 2/3

Multiply by 3

3/x + 6/x + 10 = 2

Multiply by x

2 + 6x/x + 10 = 2x

Multiply by x + 3

2(x + 10) + 6x = 2x(x + 3)

2x+20+6x=2x^2+6x

-2x^2+2x+20=0

x=3.70

hence y

x + 10 = y

3.70+ 10 = y

y=13.7

In conclusion,  the two integers are

x=3.70

y=13.7
