Write 34/7 as a mixed number in simplest form
Dvinal [7]
The answer is 4 6/7

Explanation:

34 goes into 7, 4 times so that would be four wholes and the remainder would go over seven
So 34-28 = 6

Therefore, you would get 4 6/7.

Which of the following is a root of the polynomial function below
VMariaS [17]

Answer:

A) 2 + i

Step-by-step explanation:

F(x) = x^3 - 3x^2 + x + 5

0 = x^3 - 3x^2 + x + 5

0 = (x+1)(x^2 - 4x + 5)

Great, now we can separate these two parenthesis expressions because of the Zero Product Property. Start with the simple one:

0 = x + 1

<u>x = -1</u>

We have our first real root! But it doesn't look like that's one of the answer choices, so move on to the other expression:

0 = (x^2 - 4x +5)

This expression can't be factored, so we will use the quadratic formula (which is x = \frac{-b+-\sqrt{b^{2}-4ac }  }{2a}).

First solve for the positive part:

= (4 + sqrt(16-20)) / 2

  = 4 + sqrt(-4) / 2

  = 4 + 2i / 2

  <u>= 2 + i</u>

Then for the negative part:

= (4 - sqrt(16-20)) / 2

  = 4 - sqrt(-4) / 2

  = 4 - 2i / 2

  <u>= 2 - i</u>

<u></u>

<u>2 + i</u> is answer choice A! Our other roots, <u>2 - i</u> and <u>-1</u>, aren't answer choices.

Lynna [10]

Answer:

11 6/9

Step-by-step explanation:

Daniel works in a market

He has large bags of potatoes that weighs 26 1/4

Daniel is going to sell them in smaller bags 9/4 pounds each

Therefore the number of smaller bags of potatoes in which Daniel would have filled can be calculated as follows

= 26 1/4 ÷ 9/4

= 105/4 ÷ 9/4

= 105/4 × 4/9

= 105/9

= 11 6/9

Answer:

Perpendicular = Y = 34.64 ft (Approx)

Base = X = 20 ft

Step-by-step explanation:

Given:

θ = 60°

Hypotenuse = 40 ft

Perpendicular = Y

Base = X

Find:

X and Y

Computation:

Sinθ = Perpendicular / Hypotenuse

Sin 60 = Y / 40

Perpendicular = Y = 34.64 ft (Approx)

Cosθ = base / Hypotenuse

cos 60 = X / 40

Base = X = 20 ft
