Flauer [41]2 years ago

Answer:

The two numbers are 29 and 18

Step-by-step explanation:

Let x and y be the two numbers

x = 2y-7

x+y = 47

We have two equations and 2 unknowns

Substituting the first equation into the second equation

2y-7+y = 47

Combine like terms

3y -7 = 47

3y-7+7 = 47+7

3y = 54

Divide by 3

3y/3 = 54/3

y = 18

Now find x

x = 2y-7

x = 2*18 -7

x = 36-7

x = 29

The two numbers are 29 and 18

In order for smallest to largest is 70% 2/3, 0.62,13/20,0.6
likoan [24]

Answer:

70% = 0.70

2/3 = 0.667

0.62

13/20 = 0.65

0.6 = 0.60

0.6 < 0.62 < 13/20 < 2/3 < 70%

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
alexandr402 [8]

Answer:

\frac{d\,arccos(x)}{dx} =-\frac{1}{\sqrt{1-x^2} }

See the proof below

Step-by-step explanation:

if  y=arccos(x), then :  cos(y)=cos(arccos(x))=x

We can then apply the derivative to both sides of this last equation and remember to use the chain rule as we encounter the variable "y":

cos(y)=x\\\frac{d}{dx} cos(y)=\frac{d}{dx} x\\-sin(y)\,\frac{dy}{dx} =1\\\frac{dy}{dx} =-\frac{1}{sin(y)} \\\frac{dy}{dx} =-\frac{1}{\sqrt{1-cos^2(y)} }\\\frac{dy}{dx} =-\frac{1}{\sqrt{1-x^2} }\\\frac{d\,arccos(x)}{dx} =-\frac{1}{\sqrt{1-x^2} }
