Answer:

  D. Factor out 3 from the first two terms.

Step-by-step explanation:

Vertex form is ...

  y = a(x -h)² +k

where (h, k) is the vertex and "a" is the vertical scale factor.

This equation expands to give ...

  y = ax² -2ahx + ah² +k

Factoring "a" from the terms involving x makes it easy to identify h and so finish putting the equation into vertex form. In this equation, that means the most appropriate first step is ...

  factor out 3 from the first two terms

Answer:

D. Factor out 3 from the first two terms.

Step-by-step explanation:

According to the Vertex Formula [y = A(X - H)² + K], -H gives you the OPPOSITE terms of what they really are, but in this case, this would not qualify, since the question is asking something totally unique. So, since 3 is your "A", you factor that out, and since 6 is a multiple of 3, it is easy to work with. Anyway, you get this:

y = 3(x + 1)² - 11

I hope this helps you out alot, and as always, I am joyous to assist anyone at any time.

Answer:

D

Step-by-step explanation:

x=-3 is a zero means x+3 is a factor

x=5/4 (with multiplicity 2) means you have the factor (x-5/4) two times

Now this may be rewritten so you don't have the fraction

like 4x=5 so you have 4x-5 as a factor two times which means you will see (4x-5)^2

So you one factor of (x+3) and two factors of (4x-5)

so you have

(x+3)(4x-5)^2

or

2(x+3)(4x-5)^2

or

41(x+3)(4x-5)^2

You can put whatever constant multiple in front of the whole thing and it will still satisfy the conditions of the problem.

So the answer is D

Final answer:

The factored form of the polynomial p(x) with a simple zero at x=-3 and a double zero at x=5/4 is (x+3)(4x-5)
, which makes option D the correct answer.

Explanation:

If p(x) is a polynomial that has a simple zero at x=-3 and a double zero at x=5/4, then to identify the correct factored form of p(x), we need to determine the factors that correspond to these zeros. A simple zero at x=-3 suggests that (x+3) must be a factor of p(x). A double zero at x=5/4 indicates that the factor corresponding to this zero should be squared in the polynomial, and since 5/4 can be written as 5/4 = 4/4 + 1/4 = 1 + 1/4, thus, the factor is (x-1-1/4), which simplifies to (x - 5/4) or (4x - 5) when multiplied by 4 to clear the fraction.

Looking at the options presented:

A) p(x)=2(x+3)(5x-4) - This has the correct factor for x=-3 but not the squared factor for x=5/4.

B) p(x)=(x+3)(5x-4)
- This has the correct factor for x=-3 but not the squared factor for x=5/4.

C) p(x)=2(x+3)(4x-5) - This has the correct factors but does not square the (4x-5) factor for the double zero at x=5/4.

D) p(x)=(x+3)(4x-5)² - This option correctly includes (x+3) for the simple zero at x=-3 and (4x-5) squared for the double zero at x=5/4.

Therefore, the correct factored form of p(x) is option D.

Answer:

  1041

Step-by-step explanation:

Among the numbers 1–1000, there are 31 squares, so the sequence will extend to at least 1031. In those added numbers, there is another square (1024), so the sequence must extend to at least 1032.

There are 7 more numbers that are cubes, but not squares, so the sequence must extend to at least 1039.

And there are 2 additional numbers that are 5th powers that are not squares or cubes. Compensating for the removal of these numbers extends the end of the sequence to 1041.

There are no numbers in this range that are both cubes and 5th powers and that have not already been accounted for. (The only 15th power is 1.)

Hence, the 1000th number in the sequence is 1041.

_____

This result is verified by a computer program that listed the numbers.

The 1000th term, 1041, is in the sequence of positive integers that aren't squares, cubes, or fifth powers.

The sequence begins with 2, which is not a perfect square, cube, or fifth power.

It continues with 3, which is also not a perfect square, cube, or fifth power.

It skips numbers like 4, 5 (as 5 is a perfect fifth power), 6, and 7 (as they are squares or cubes).

The sequence picks up with 10 and 11, which are not perfect squares, cubes, or fifth powers.

This pattern continues, with the sequence skipping over numbers that meet any of the three conditions.

When you reach the 1000th term, it should be a number that satisfies these conditions, and that number is 1041.

So, you found the 1000th term by observing the pattern of the sequence and determining that it is neither a perfect square, cube, nor fifth power. Your answer of 1041 is correct for the 1000th term in this sequence.

Answer:

  opens down; (10, 2); same

Step-by-step explanation:

If the vertex of f(x) is (0, 0) then translating it to (h, k) makes the function look like f(x -h) +k. Changing the sign of f(x) to -f(x) reflects it across the x-axis, so ...

  y = 2 - |x -10|

is the function y = |x| reflected across the x-axis and translated 10 units right and 2 units up. Because there is no horizontal or vertical scale factor, the apparent width of the function is the same as the original.

Final answer:

The graph of the function y = 2 - |x – 10|  a .opens down with a vertex at (10, 2). It has the same width as the graph of y = |x|, meaning it is not stretched or compressed horizontally, but it is shifted upward and to the right.

Explanation:

To determine whether the graph of the function y = 2 - |x – 10| opens up or down, we must understand the behavior of the absolute value function. Since the absolute value function has a V-shape, the negative sign in front of the absolute value in the given function indicates that the graph opens down, creating an upside-down V-shape. Furthermore, the vertex of the graph is at the point where the expression inside the absolute value equals zero. In this case, x – 10 = 0, so x = 10. Plugging this into the function gives us the y-coordinate of the vertex, which is y = 2 - |10 - 10| = 2. Therefore, the vertex is (10, 2).

Comparing the width of the graph to the graph of y = |x|, we notice that there is no multiplication factor affecting the x inside the absolute value, hence the graph of the given function has the same width as the graph of y = |x|. In other words, the graph is neither stretched nor compressed horizontally. Rather, it is vertically shifted upward by 2 units, and horizontally shifted to the right by 10 units due to the x – 10 part of the function.

Answer:

The vertex is: [tex](6, 8)[/tex]

Step-by-step explanation:

First solve the equation for the variable y

[tex]x^2-4y-12x+68=0[/tex]

Add 4y on both sides of the equation

[tex]4y=x^2-4y+4y-12x+68[/tex]

[tex]4y=x^2-12x+68[/tex]

Notice that now the equation has the general form of a parabola

[tex]ax^2 +bx +c[/tex]

In this case

[tex]a=1\\b=-12\\c=68[/tex]

Add [tex](\frac{b}{2}) ^ 2[/tex] and subtract [tex](\frac{b}{2}) ^ 2[/tex] on the right side of the equation

[tex](\frac{b}{2}) ^ 2=(\frac{-12}{2}) ^ 2\\\\(\frac{b}{2}) ^ 2=(-6) ^ 2\\\\(\frac{b}{2}) ^ 2=36[/tex]

[tex]4y=(x^2-12x+36)-36+68[/tex]

Factor the expression that is inside the parentheses

[tex]4y=(x-6)^2+32[/tex]

Divide both sides of the equality between 4

[tex]\frac{4}{4}y=\frac{1}{4}(x-6)^2+\frac{32}{4}[/tex]

[tex]y=\frac{1}{4}(x-6)^2+8[/tex]

For an equation of the form

[tex]y=a(x-h)^2 +k[/tex]

the vertex is: (h, k)

In this case

[tex]h=6\\k =8[/tex]

the vertex is: [tex](6, 8)[/tex]

Answer:

Number of cards at week n = 10,000(0.85)^(n-1).

At week 6  Dylan has 4437 cards.

Step-by-step explanation:

At the start of week 1 he had 10,000 = 10,000(0.85)^0  cards.

So at the start of week 2 he had 10,000(0.85)^(2-1) cards.

Number of  cards for week n =  10,000(0.85)^(n-1).

Number of he will have at the start of the 6th week

= 10,000(0.85)^(6-1)

=  4437 cards (answer).

The explicit rule for the number of baseball cards Dylan starts with in week n is A(n) = 10,000 * 0.85ⁿ⁻¹. In the 6th week, Dylan will start with approximately 4437 cards.

The number of baseball cards Dylan starts with in week n can be represented by an explicit rule, which is a formula that uses the starting amount of cards and a common ratio to find the amount for any given week. The starting number of cards for week n can be calculated using the geometric sequence formula: A(n) = A(1) * rⁿ⁻¹, where A(1) is the initial number of cards, r is the ratio of the remaining cards per week (85%, or 0.85), and n is the week number.

To calculate the number of cards Dylan starts with in the 6th week, we use the formula with A(1) = 10,000, r = 0.85, and n = 6:
A(6) = 10,000 * 0.85⁶⁻¹

After performing the calculations and rounding to the nearest card, Dylan will start with approximately 4437 cards in the 6th week.

Step-by-step explanation:

Assuming the hole in the bottle is not made any bigger as it loses water, it will lose it at a constant rate.  This makes it a linear function.  We can use the 2 points given to find the slope of the line, then use one of the 2 points to write an equation for the line in point-slope form, change it into slope-intercept form, and the amount of water in the bottle originally will be apparent.  Plugging in to the slope formula:

[tex]m=\frac{20-28}{6-2}=-2[/tex]

Now we will choose one point for the x and y values and plug in to the point-slope form of a line:

y - 28 = -2(x - 2) and

y - 28 = -2x + 4 so

y = -2x + 32

That is in y = mx + b form where m is the slope and b is the y-intercept, the initial value of y when x = 0.  x being the time gone by, when x = 0, that means that no time has gone by, and that means that no water has yet to leak out of your bottle.

From the diagram, [tex]\angle BAD=2x\degree[/tex] and [tex]\angle BCD=(10x+24)\degree[/tex]

In an isosceles trapezium, the base angles are equal.

This implies that [tex]\angle ABC=\angle BAD[/tex]  [tex]\implies \angle ABC=2x\degree[/tex]

The side length CB of the trapezoid is a transversal line because CD is parallel to AB.

This means that [tex]\angle ABC=2x\degree[/tex] and [tex]\angle BCD=(10x+24)\degree[/tex] are co-interior angles.

Since co-interior angles are supplementary, we write and solve the following equation for [tex]x[/tex].

[tex]2x\degree+(10x+24)\degree=180\degree[/tex]

Group similar terms

[tex]2x+10x=180-24[/tex]

Answer:

x=-1 is a maximum vaue.

Step-by-step explanation:

To find the minimum and maximum values of the function f(x), we're going to derivate it:

f(x) = –5x^2 – 10x + 6 ⇒ f'(x) = -10x - 10

The points where f'(x) is zero, could be a maximum or a minimum. Then:

f'(x) = -10x - 10 = 0 ⇒ x=-1

Now, to know if x=-1 is a maximum or a minimum, we need to evaluate the original function for x when it tends to -1 from the right and from the left.

Therefore:

For x=-2:

f(x) = 6 (Positive)

For x=0:

f(x) = 6 (Positive)

For x=-1

f(x) = 11 (Positive)

Given that at x=-1, f(x) = 11, and then it goes down to 6 when x=0, we can say that it's a maximum.

Answer:

max at (-1,11)

Step-by-step explanation:

f(x) = –5x^2 – 10x + 6

This parabola opens downward

f(x) = ax^2 + bx+c

The value a is negative, so it opens down.

Because it opens down, it will have a maximum

We can find the x value of the maximum by finding the axis of symmetry

h = -b/2a

h = -(-10)/2(-5)

  = 10/-10

h= -1

The x value of the vertex is -1

To find the y value, substitute this back into the equation

f(-1) = -5( -1)^2 - 10(-1) +6

       =-5(1) +10+6

       =-5 +10+6

     =11

The maximum is at (-1,11)
