Using the recursion equation, it is found that the value of the 2nd iterate is:

$x_2 = 3.16228$

<h3>What is the recursive equation?</h3>

The value of the nth iteration is given by:

$x_n = \frac{x_{n-1} + \frac{10}{x_{n-1}}}{2}$

The initial estimate is:

$x_0 = 3.1$

Hence, the 1st iterate is given by:

$x_1 = \frac{x_0 + \frac{10}{x_0}}{2} = \frac{3.1 + \frac{10}{3.1}}{2} = 3.1629$

The 2nd iterate is:

$x_2 = \frac{x_1 + \frac{10}{x_1}}{2} = \frac{3.1629 + \frac{10}{3.1629}}{2} = 3.16228$

Thus, the fourth option is correct.

Two lawn care companies are competing for a landscaping contract. Company A charges a $300 consulting fee plus $7 per square foo

kkurt [141]

The square feet of landscaping will the two companies carry out that enables them to charge the same amount is 30

What is the total of the landscaping contract for each company?

The total cost of the landscaping contract for each of the two companies is the sum of the fixed consulting fee plus the multiple of variable charge per square foot multiplied by the number of square feet of landscaping

Company A:

Total cost=300+7S

S=square foot

Company B:

Total cost=120+13S

At the point where the square foot are the same they charge the same amount

300+7S=120+13S

300-120=13S-7S

180=6S

S=180/6

S=30 square foot

How do u do b??????????

horrorfan [7]

the assumption being that the first machine is the one on the left-hand-side and the second is the one on the right-hand-side.

the input goes to the 1st machine and the output of that goes to the 2nd machine.

if she uses and input of 6 on the 2nd one, the result will be 6² - 6 = 30, if we feed that to the 1st one the result will be √( 30 - 5) = √25 = 5, so, simply having the machines swap places will work to get a final output of 5.

clearly we can never get an output of -5 from a square root, however we can from the quadratic one, the 2nd machine/equation.

let's check something, we need a -5 on the 2nd, so

$\bf \underset{final~out put}{\stackrel{y}{-5}}=x^2-6\implies 1=x^2\implies \sqrt{1}=x\implies 1=x$

so if we use a "1" as the output on the first machine, we should be able to find out what input we need, let's do that.

$\bf \underset{first~out put}{\stackrel{y}{1}}=\sqrt{x-5}\implies 1^2=x-5\implies 1=x-5\implies 6=x$

so if we use an input of 6 on the first machine, we should be able to get a -5 as final output from the 2nd machine.

$\bf \stackrel{first~machine}{y=\sqrt{\boxed{6}-5}}\implies y=\sqrt{1}\implies y=1 \\\\\\ \stackrel{second~machine}{y = \boxed{1}^2-6}\implies y = 1-6\implies y = -5$

The equation of a parabola is given.

Irina18 [472]

y = −1/4x^2 + 4x − 19

1. Use x = -b/2a to find x.

x = -4/2(-1/4)

x = -4/(-1/2)

x = -4/1 • (-2/1)

x = 8/1

x = 8

2. Plug x into the function to find your vertex.

Replace every x you see in the function with 8 and do the math.

Take it from here.
