Answer:

The area of a rectangle is 520 square inches. The length is 3 more than twice the width. The equation 520 = 2w2 + 3w can be used to find the length and width of the rectangle.

Step-by-step explanation:

1st statement:

l= 2w+3

A= l × w

520= w×(2w+3)

520= 2w²+ 3w

2nd statement:

length of fencing= w+2l

120= w+2l

l= 60-w/2

A= (60-w/2) × w

A= 60w- w²/2

Hence this statement is incorrect

3rd statement:

H= x

B= x-4

P= x-2

Accoriding to pythagoras theorem

H²=P²+B²

x²=(x-4)²+(x-2)²

x²= x²-8x+16 + x²-4x+4

0= x²-12x+20

Hence this statement is incorrect

4th statement:

two consecutive even numbers are given by n and n+2

So this statement is incorrect

wariber [46]

Answer:

4 square feet

Step-by-step explanation:

We can use Ratio to solve this question

It takes 15 minutes to paint 60 square feet

This is written as:

15:60

Divide both sides by 15

1:4

Therefore it takes Painter Paul 1 minute to paint 4 square feet

Prove the formula for (d/dx)(cos−1(x)) by the same method as for (d/dx)(sin−1(x)). Let y = cos−1(x). Then cos(y) = and 0 ≤ y ≤ π

gtnhenbr [62]

Answer:

$\frac{d(cos^{-1}x )}{dx} = \frac{-1}{\sqrt{1-x^2} }$

Step-by-step explanation:

Given the differential (d/dx)(cos−1(x)), to find the equivalent formula we will differentiate the inverse function using chain rule as shown below;

let;

$y = cos^{-1} x \\\\taking \ cos\ of\ both\ sides\\\\cosy = cos(cos^{-1} x)\\\\cosy = x\\\\x = cosy\\\\\frac{dx}{dy} = -siny\\$
