Answer:

Explanations:

From the question, we are to use synthetic division to divide x - 1 by the polynomial function -3x^3 - 2x^2 - 1

Next is to use the synthetic division to carry out the operation as shown below;

From the calculation above, we can conclude the following;

The answer to g(f(x)) expressed as a polynomial in Standard form is x² + 6x + 13.

Given the composition of functions g(f(x)),

For which f(x) = x + 5, and g(x) = x² - 4x + 8.

Considering f(x) as input we substitute it in g(x) in place of x.

g(f(x)) = (x+5)²- 4(x+5) + 8

         = x² + 25 + 10x - 4x -20 + 8

        = x² + 6x + 13

B(4,4)

The segment is reflected over the line y =4

The line y=4 is a horizontal line, coordinate in x doesn't change after reflection.

To find coordinate y after reflection:

Find the distance of each point from y=4

As y=4 is below the point A, the point A' will have a coordinate y of: 4-3=1

As point B is on line y=4 the point B' will have a coordinate y of 4-0:4

then rotated 90° CW:

Rule for a rotation 90º CW:

Then, you get the next coordinates for A'' and B'':

(g o f)(-8) = 36

For f(x) = 2x + 12 and g(x) = 2x² + 2x + 12 the value of (g o f)(-8) is 36.

Given that f(x) = 2x + 12, g(x) = 2x² + 2x + 12.

to locate (g o f) (-8),

To find (g o f)(-8), we must first find g(f(x)) and then substitute x = -8.

Find g(f(x)) by substituting f(x) into g. (x)

= g(f(x))  = 2( 2x +12)² + 2( 2x + 12) + 12

x = -8 so,

g( f( - 8) ) = 2( 2(-8) +12)² + 2( 2(-8) + 12) + 12

g( f( - 8) ) = 2( -16 +12)² + 2( -16 + 12) + 12

g( f( - 8) ) = 2(-4)² + 2( -4 ) + 12

g( f( - 8) ) = 2 x 16 -8 + 12

g( f( - 8) ) = 32 - 8 + 12

g( f( - 8) ) = 36

So (g o f)(-8) = 36

Answer:

x>0

Step-by-step explanation:

any number less than or equal to zero does not give a negative solution and you need a negative solution so x must be greater than 0

1) Considering that we can call t-shirts "x" then we can write out the following equations to express this problem:

Robert: 2x +3

Brianne: x

2) Now, we can write out the following equation to find out how many t-shirts does Brianne have:

So that's the number of t-shirts Brianne has. And the equation used is:

Notice that triangles QRS and YRZ are similar, therefore:

Answer: Option C).

2ab + c²

(a+b)² and a² + 2ab + b²

2ab

1) Examining that picture, we can state the following about that:

The shaded triangles area:

Note that the area of the triangle is 1/2 the product of the base by its height.

The area of that white inner square is given by c² since the Area of a square is equal to the side length raised to the 2nd powe.

2) Then

The expression 2ab + c² represents the area...

The equivalent expressions (a+b)² and a² + 2ab + b² use the length of the figure (a square) raised to the 2nd power. As explained above.

For the last statement let's calculate it:

2ab + c² = (a+b)²

a² +2ab + b² = 2ab +c² Subtracting 2ab

a² +b² = c²

3) Hence, the answers are:

2ab + c²

(a+b)² and a² + 2ab + b²

Answer:

20.36

Step-by-step explanation:

72.60 cuando se divide por 100 se obtiene 1% o 0.73x8=5.84
entonces 72.60/10=7.26x2=20% o 14.52

14.52+5.84=20.36

Reason:

There aren't any repeated items in the domain. Each x input goes to exactly one y output. This is why we have a function.

The y values can repeat, but the function wouldn't be one-to-one (i.e. injective).

Answer: D and C are the other rotations

The Poisson distribution is a discrete distribution that calculates the likelihood that a certain number of events will occur within a certain amount of time.

The probability of getting exactly three robberies in a day is 0.1607.

The Poisson distribution is a discrete probability distribution used in probability theory and statistics to express the likelihood that a given number of events will occur within a specified time or space interval if they occur at a known constant mean rate and regardless of the interval since the last event.

The Poisson distribution is a discrete distribution that calculates the likelihood that a certain number of events will occur within a certain amount of time.

In the poison distribution a discrete random variable X has the following probability mass function,

[tex]$P(X=x)=\frac{e^{-\lambda} \cdot \lambda^x}{x !}$[/tex], where [tex]$\lambda$[/tex] is the mean of the distribution and [tex]$x=0,1,2,3 \ldots \ldots$[/tex]

Given that [tex]$\lambda=1.8$[/tex]

The required probability, [tex]$P(X=3)=\frac{e^{-1.8} .(1.8)^3}{3 !}=0.1607$[/tex]

To make 12 pancakes we need 100 g flour, 2 eggs, 300 ml milk

Abdul has 175 g flour, 4 eggs and 500 g milk

The ration between Abdul's amount of each ingredient and the total needed to make 12 pancakes is: (175/100) = 1.75 flour, (4/2) = 2 eggs, (500/300) = 1.67 milk.

So, the total amount of pancakes that Abdul can make is determined by the amount of the less abundant ingredient (milk): 1.67*12 = 20 pancakes

Doing the same steps for Beckie, we got that her less abundant ingredient is milk, with a ratio of 400/300 = 1.33. Then, she can make 1.33*12 = 16 pancakes.

For Cynthia, her less abundant ingredient is flour, with a ratio of 150/100 1.5. Then, she can make 1.5*12 = 18 pancakes.

And for Douglas, his less avundant ingredient is egg, with a ratio of 3/2 = 1.5. Then, he can make 1.,5*12 = 18 pancakes.

Therefore, Abdul is the one who can make the most pancakes

The plant food should Miguel add to 7 cups of water is 336 plant food

What is Algebra?

One of the many different mathematical disciplines is algebra. Algebra, a common thread that runs through nearly all of mathematics, is the study of mathematical symbols and the rules for using them in formulas.

To feed his plants, Miguel combines water and plant food. According to the directions on the plant food, you should add 1 teaspoon to every 4 cups of water. To demonstrate the relationship between cups of water (w) and teaspoons of plant food (f), create an equation.

48 teaspoons = 1 cup.

1 teaspoon = plants food

4 cups =  water.

= 48 teaspoons x 4.

= 192 teaspoons

The formula is:

water in cups = w

Teaspoon of nourishment for plants equals f

The mixture = 192w + f

The relation between  f and w is f = kw.

1 teaspoon = plant food

7 cups = water.

= 48teaspoon x 7

= 336teaspoon

The formula is:

water in cups = w

Teaspoon of nourishment for plants equals f

The mixture = 336w + f

Hence, 336 plant food  should Miguel add to 7 cups of work

Answer:

y = 0

Step-by-step explanation:

The function has a horizontal asymptote at y = 0 where y is the value of the car

[tex]\text{Since the equation for the value of the car is }[/tex]  [tex]23000(1-0.15)^t[/tex]

As [tex]t \rightarrow \infty, \text{the term } (1-0.15)^t \rightarrow 0 \\[/tex]

This is because the term (1-0.15) is < 1 and a nˣ approaches 0 as x → ∞ since the values get smaller and smaller with increasing powers of x

So the equation for the horizontal asymptote is y = 0

range = 16

Step-by-step explanation:

The total of all the numbers = mean x number of values = 6 x 12 = 72

The ratio of the numbers is

1: 1: 1: 1:2 :3

The sum of the ratios is 9

So the numbers in the ratio of 1 must be 1/9 x 72 = 8

The number with a ratio of 2 must be 2 x 8 = 16

and finally the number with the ratio of 3 = 3 x  = 24

The range of the numbers is 24-8 = 16
