Answer:

Possible rational roots: ±1,±5.

Actual rational roots: −1,5.

Step-by-step explanation:

The trailing coefficient (coefficient of the constant term) is −5.

Find its factors (with plus and minus): ±1,±5. These are the possible values for p.

The leading coefficient (coefficient of the term with the highest degree) is 1.

Find its factors (with plus and minus): ±1. These are the possible values for q.

Find all possible values of pq: ±11,±51.

Simplify and remove duplicates (if any), these are possible rational roots: ±1,±5.

Next, check the possible roots: if a is a root of the polynomial P(x), the remainder from the division of P(x) by x−a should equal 0.

Check 1: divide x3−3x2−9x−5 by x−1.The quotient is x2−2x−11 and the remainder is −16  

Check −1: divide x3−3x2−9x−5 by x+1.The quotient is x2−4x−5 and the remainder is 0  

So, −1 is a root.

Check 5: divide x3−3x2−9x−5 by x−5.The quotient is x2+2x+1 and the remainder is 0  

So, 5 is a root.

Check −5: divide x3−3x2−9x−5 by x+5.The quotient is x2−8x+31 and the remainder is −160  

Answer:

AGHI

Step-by-step explanation:

I took the quiz on edgenuity

The triangle where one reflection necessary for the transformation to occur is triangle GHI.

A triangle is known to be a polygon that is made up of three edges and it is one that also has three vertices.

Note that order of arrangement of the vertices in ΔABC can be regarded as a clockwise direction. The same is with the images except for the one of  ΔGHI. A reflection is needed when reversing a sequence of vertices. but only one reflection is needed to obtain an image like that of ΔGHI.

Write each set in the indicated form.

If you need to use "..." to indicate a pattern, make sure to list at least four elements of the set.

As you answer below, remember that the natural numbers are just the counting numbers. This means that is not a natural number, and negative numbers are not natural numbers either.

(a) Roster form: {6,8,10,12,...}

Descriptive form:

(b) Descriptive form: The set of natural numbers greater than or equal to 3 and less than or equal to 6.

Roster form:

Answer:

A) Descriptive form: A set of even natural numbers that are greater than or equal to 6.

B) Roster form: {3, 4, 5, 6}

Step-by-step explanation:

A) We are given that the roster form is;

{6,8,10,12,...}

Now, the descriptive form is just a statement that describes the given roster form.

Now, we can see they are all even natural numbers and the least is 6 while after 12,we can see that the set continues.

Thus;

Descriptive form: A set of even natural numbers that are greater than or equal to 6.

B) We are given that the descriptive form is the set of natural numbers greater than or equal to 3 and less than or equal to 6.

This means the least number in the set is 3 while the highest number is 6.

Thus,the roster form is;

Roster form: {3, 4, 5, 6}

When we put toast in the toaster he didn't do anything but heat up the toast, so the property and identity of this piece of toast hasn't changed at all. When we put jam and peanut butter on it all it did was add flavor to it still didn't change the identity. But when we cut the apple in to a lot of slices the property of the apple has changed and the weight is different and the chemical property isn't the same. ( it is totally different)

The pool is 400 square meters

Step-by-step explanation:

To figure out the are of a slanted shape such as this, we must turn it into a shape that is non-slanted, like a rectangle or square (which is a type of rectangle). For this parallelogram, we can separate the shape into three parts: the two slanted bits on the outside, and a rectangle (7*2) in the middle (or on the inside).

We can see that each slanted part can take up half of two squares, and therefore one square. From here on out, we can do this one of two ways:

1. Figure out the area of the inside rectangle, then add the two slanted parts/two squares separately

OR

2. Since each slanted area equals one square, or since each is half of two square, we can add both sides together (for 1/2 + 1/2 = 1, or in this case,        1 +1 = 2), to make a full or complete rectangle, before figuring out the area of the shape as a whole (8*2).

8*2 = 16

Each square is 1 cm squared, which is in proportion to 25 meters squared (each cm is 5 meters (1:5), so the square, which is 1 cm by 1 cm, is proportionate to 5 meters by 5 meters).

16*25 = 400

The pool is therefore 400 square meters.

About 6 gallons of paint

Step-by-step explanation:

[tex]\frac{0.5}{84}[/tex]  =  [tex]\frac{x}{932}[/tex]

84x=932(0.5)

84x=466

x  =  5.55

round up to get about 6 gallons of paint

The number of the gallon of paint is need will be 5.547 gallons of paint.

A ratio is a collection of ordered integers a and b represented as a/b, with b never equaling zero. A proportionate expression is one in which two items are equal.

Joel used a half gallon of paint to cover 84 square feet of wall.

Then in one gallon of paint he can cover 168 square feet.

He has 932 square feet of walls of paint.

Then the number of the gallon of paint is need will be

⇒ 932 / 168

⇒ 5.547 gallons of paint

Answer:

3.6 feet

Step-by-step explanation:

The height of the rollercoaster in feet throughout the underground section is modeled by the equation :

[tex]h(d) = 0.15d^2 - 1.5d[/tex] ....(1)

We need to find the height of the rollercoaster 6 feet horizontally through the underground section.

Put d = 6 feet in equation (1) as follows :

[tex]h(6) = 0.15(6)^2 - 1.5(6)\\\\h=-3.6\ \text{feet}[/tex]

or

h = 3.6 feet

So, the height of the rollercoaster 6 feet horizontal through the underground section is 3.6 feet.

Answer:

Andy can make 26 bags for the display.

Step-by-step explanation:

Quantity of apples in the back of the store = 39 pounds

Quantity of apples in one bag = [tex]1\frac{1}{2}[/tex] pounds

Here,

[tex]1\frac{1}{2}=\frac{2(1)+1}{2}=\frac{3}{2}[/tex]

Number of bags = Quantity of apples in the back of the store / Quantity of apples in one bag

[tex]=\frac{39}{1\frac{1}{2} }=\frac{39}{\frac{3}{2} }=39(\frac{2}{3})=26[/tex]

So, Andy can make 26 bags for the display of apples.

Given: : Time taken by Julius to complete the job alone: [tex]T_1=2\text{ hours}[/tex]

Time taken by Marcos to complete the job alone : [tex]T_2=3\text{ hours}[/tex]

Let the time taken by both to complete the job together = T

[tex]\dfrac{1}{T}=\dfrac{1}{T_1}+\dfrac{1}{T_2}[/tex]

[tex]\Rightarrow\ \dfrac{1}{T}=\dfrac{1}{2}+\dfrac13\\\\\Rightarrow\ \dfrac{1}{T}=\dfrac{3+2}{2\times3}\\\\\Rightarrow\ \dfrac{1}{T}=\dfrac{5}{6}\\\\\Rightarrow\ T=\dfrac{6}{5}=1.2[/tex]

Hence, it will take 1.2 hours to complete the job by working together.

Answer: I recommend starting treatment immediately. If you take more than 8 days to make a decision, the disease can no longer be cured because it will affect more than 50% of the body.

Step-by-step explanation:

The percentage of the body affected by the disease is a function of the number of days:  

This percentage is a dependent variable and the number of days is the independent variable.

If we give values to d, we can calculate the percentage of the body affected by the disease.

P(1)= 6·1 + 5 = 11%

P(2)= 6·2 + 5 = 17%

P(3)= 6·3 + 5 = 23%

P(4)= 6·4 + 5 = 29%

P(5)= 6·5 + 5 = 35%

P(6)= 6·6 + 5 = 41%

P(7)= 6·7 + 5 = 47%

P(8)= 6·8 + 5 = 53%

Depending on the days since the beginning of the disease, the doctors have a treatment for a different stage.

Starting immediately, the treatment will be stage 1: less than 15%

Starting on day 2 or 3, the treatment will be stage 2: 15-25%

After day 3, the treatment will be stage 3: 25-50%

After day 8, there is no cure: more than 50% of the body is affected by the disease.

I recommend starting treatment immediately. If you take more than 8 days to make a decision, the disease can no longer be cured because it will affect more than 50% of the body.
