Julie figures that she will need at least 540 Marks (German money) to get the items she wants when visiting Germany. Give an estimating example of how Julie could guarantee herself of having at least 540 Marks. Show and explain your example below.

1 is the smallest possible integer.

Given that: .

The discreminant of this equation is:

For imaginary zeros, we must get discreminant less than 0.

So,

Next integer of 0.2 is 1.

So 1 is the smallest possible integer.

The question is incomplete, the complete question is

Determine the smallest integer value of a for which f(x) = ax² - 2x + 5 has imaginary zeroes. Show how you found  this answer

Answer:

The smallest integer value of a is 1

Step-by-step explanation:

To find the zeroes of a function equate it by 0, then find the values of x which are the zeroes of the function

To find the types of the roots (zeroes) of a function f(x) = ax² + bx + c use the discriminant of the function b² - 4ac

• If b² - 4ac > 0, then the function has two different real roots
• If b² - 4ac = 0, then the function has one real root
• If b² - 4ac < 0, then the function has no real roots (imaginary roots)

∵ f(x) = ax² - 2x = 5

- To find its zeroes equate f(x) by 0

∴ ax² - 2x + 5 = 0

∵ f(x) has imaginary zeroes

- That means the discriminant is less then zero

∴ b² - 4ac < 0

∵ a = a, b = -2 and c = 5

- Substitute them in the inequality above

∴ (-2)² - 4(a)(5) < 0

∴ 4 - 20 a < 0

- Add 20 a to both sides

∴ 4 < 20 a

- Divide both sides by 20

∴ 0.2 < a

- That means a is greater than 0.2

∴ a > 0.2

∵ You must to find the smallest integer value of a

- The first integer greater than 0.2 is 1

∴ a = 1

The smallest integer value of a is 1

Answer:

1 1/3 x 1 1/3 = 1.77777777778

Irrational number because it cannot be expressed as a fraction of two whole numbers and it has no accurate decimal equivalent.

So its  Irrational hope this helped :)

Answer:

yes it is irrational

Step-by-step explanation:

Answer:

The length of the scarf is at least 42 inches and at most 48 inches.

Step-by-step explanation:

We are given the following information:

Length of trim = 3 yards = 108 inches

The width of the scarf to be a whole number that is at least 6 inches and at most 12 inches.

Let w be the width of the scarf and l be the length of scarf.

Perimeter of scarf =

Then, we can write:

The length of the scarf is at least 42 inches and at most 48 inches.
