The 300th customer would be the first to recieve both. They would have given away 5 of the 20$ gift cards and 12 of the 10$ ones for a total of 17 gift cards.

Approximate the solution to the equation above using three iterations of successive approximation. Use the graph below as a star
n200080 [17]

Answer:

<em>x=25/16</em>

Step-by-step explanation:

<u>Approximate Roots of Functions:</u>

We are required to find the root of  

\displaystyle 5^{-x}+7=\ 2x+4

Let's construct a function

\displaystyle f(x)=\ 5^{-x}+7-2x-4

Reducing:

\displaystyle f(x)= 5^{-x}-2x+3

The equation will have a solution when f(x)=0. We'll start from the approximate crossing point given in the graph (x=1.5)

\displaystyle f(1.5)=5^{-1.5}-2(1.5)+3\ =0.089

We'll move up on x=1.52  

\displaystyle f(1.52)=5^{-1.52}-2(1.52)+3=\ 0.046

We are closer to the solution, let's try some more up

\displaystyle f(1.54)=5^{-1.54}-2(1.54)+3=\ 0.0038

This value x=1.54 is close enough to the solution of the original equation

From the options given, \frac{25}{16} is the closest to our solution

\boxed{Answer:\ x=25/16}

I need help with number 9
ololo11 [35]
The correct answer is D. 1,136
This is because when you divide 3,000 by 140 (the total amount of people surveyed) you get about 21. Then multiply 21 by the number of people who chose N. Monroe (53). That answer is 1,136.

Sven Hendriksson finds that one of his productivity measures is related to the number of employees, e, and the production, n, by
muminat

Answer:

n = 3

e = 5

Step-by-step explanation:

10n + 3e = 45

2n + 5e = 31

10n + 3e = 45

10n + 25e = 155

o + 22e = 110

e = 5

to fix 5 into the first equation

10n + 3(5) = 45

10n + 15 = 45

10n = 45 -15

10n = 30

n = 3
