I need help on #37!!
Nataliya [291]

Answer:

A) 12.1 , 12.01

B) infinitely large

Step-by-step explanation:

Give that the function f(x)=x2 describes the area of the square, f(x), in square inches, whose sides each measure x inches. If x is changing. 

Using the formula

(f(a + h) - f(a))/h

as x changes from 6 inches to 6.1 inches

a = 6, h = 0.1

= [f(6.1) - f(6)]/0.1

= (6.1^2 - 6^2)/0.1

= (37.21 - 36)/0.1

= 1.21/0.1

= 12.1

and when x changes from 6 inches to 6.01 inches. 

a = 6, And h = 0.01

Using the same formula

(f(a + h) - f(a))/h

= [f(6.01) - f(6)]/0.01

= (6.01^2 - 6^2)/0.01

= (36.120 - 36)/0.01

=0.1201/0.01

= 12.01

B) the instantaneous rate of change of the area with respect to x at the moment when x = 6 inches is infinitely large since h = 0

Solve by the linear combination method (with or without multiplication).
Dima020 [189]

The first step is to name the equations to make the process of solving them easy.

6x+7y=-4....(1)\\5x-3y=-21....(2)

The second step is to multiply  each of the equations by the coefficient of the x term in the other equation. In this case, we will multiply equation  (1) by 5 to get equation (3) and then multiply equation (2) by 6 to get equation (4).

-30x-35y=20...(3)\\30x-18y=-126...(4).

The next step is to add equation equation(3) and  (4) together to get equation (5) as shown below;

-53y=-106....(5)\\=> y= 2.

The next step is to take the value of y and substitute it into any of the equations above.  For this solution, I pick equation (1). The work done to solve for x is shown below.;

6x+7y=-4\\=>6x+7(2)=-4\\=>6x=-18\\=>x=-3

The solution for this system of equations is (-3,2)
