Notice how the entire line segment is split into 4 sections.

Section 1: 50 - 100

Section 2: 100 - 140

Section 3: 140 - 170

Section 4: 170 - 190

Since it's 4 sections, each section equals 25%

Here we need to find the percentage from 100 - 170

That means sections 2 - 3

Section 2 + Section 3 = 25% + 25% = <u>50%</u>

Simplify negative 5 minus the square root of negative 44 negative 5 minus 4 times the square root of 11 i negative 5 minus 4 i t

Anika [276]

Answer:

$-5-\sqrt{-44}=-5-2\sqrt{11}i$

Step-by-step explanation:

We want to simplify:

$-5-\sqrt{-44}$

We rewrite the expression under the radical sign to obtain:

$-5-\sqrt{4\times11\times -1}$

We split the expression under the radical sign to get:

$-5-\sqrt{4} \times \sqrt{11} \times \sqrt{-1}$

Recall that:

$\sqrt{-1}=i$

This implies that:

$-5-\sqrt{4} \times \sqrt{11} \times \sqrt{-1}=-5-2\sqrt{11}i$

Therefore $-5-\sqrt{-44}=-5-2\sqrt{11}i$

Write a polynomial function in standard form with zeros at −3, −1, and 1.

Annette [7]

Answer:

$f(x) = {x}^{3} + 3 {x}^{2} - x -3$

Step-by-step explanation:

The given polynomial has zeros at:

x=−3, x=−1, and x=1.

This means that:

x+3, x+1, and x-1 are all factors of this polynomial.

The factored form of this polynomial is :

$f(x) = (x + 3)(x + 1)(x - 1)$

We expand the last two factors using difference of two squares.

$f(x) = (x + 3)( {x}^{2} - 1)$

$f(x) = x ( {x}^{2} - 1) + 3( {x}^{2} - 1)$

$f(x) = {x}^{3} - x+ 3 {x}^{2} -3$

$f(x) = {x}^{3} + 3 {x}^{2} - x -3$

This is the standard form because it is now in decreasing powers of x.

Ean: jenny wants to make three pillow cases using fourteen feet of fabric. She plans to use an equal amount of fabric for each p

Veseljchak [2.6K]

Answer:

Approximately 4.67 feet of fabric is required for one pillow case.

Step-by-step explanation:

We are given the following in the question:

Number of pillow cases to be made by Jenny = 3

Amount of fabric Jenny has = 14 feet

Each pillow case use same amount of fabric.

Amount of fabric used to make 1 pillow case =

$=\dfrac{\text{Amount of fabric}}{\text{Number of pillow cases}}\\\\=\dfrac{14\text{ feet}}{3}\\\\\approx 4.67\text{ feet}$

Thus, approximately 4.67 feet of fabric is required for one pillow case.
