The carter family budgets a total of 2,700 for a ski vacation in Colorado if they plan to go spend 275$ per day and 1,000 on meals about how many days n can the carter family go on vacation ?

Answers

Answer:

275n + 1000 = 2700

They will go 6 days on vacation.

Step-by-step explanation:

Given that the Carter family wants to go on vacation with a budget of $ 2700, of which $ 1000 will be used exclusively for food, and for each day of stay $ 275 will be spent, the formula to obtain the number of days they can spend on vacation is following:

1000 + 275n = 2700

275n = 2700 - 1000

n = 1700/275

n = 6.18

Therefore, with this amount, the Carters will be able to spend 6 days on vacation, and they will have money left over.

which statement best describes the zeros of the function h() = (x-4)(x-7x+ 10)

O A. The function has four complex zeros.
O B. The functlon has three distinct real zeros.
O C. The function has two distinct real zeros and two complex zeros.
O D. The function has four distinct real zeros.

Answers

Answer:

The zeros are:

[tex]x =4, x=2, x = 5[/tex]

The function has three distinct real zeros.

Hence, option (B) is true.

Step-by-step explanation:

Given the expression

[tex]h\left(x\right)=\left(x-4\right)^2\left(x^2-7x+\:10\right)[/tex]

Let us determine the zeros of the function by putting h(x) = 0 and solving the expression

[tex]0=\left(x-4\right)^2\left(x^2-7x+10\right)[/tex]

switch sides

[tex]\left(x-4\right)^2\left(x^2-7x+10\right)=0[/tex]

as

[tex]x^2-7x+\:10=\left(x-2\right)\left(x-5\right)[/tex]

so

[tex]\left(x-4\right)^2\left(x-2\right)\left(x-5\right)=0[/tex]

Using the zero factor principle

[tex]\mathrm{If}\:ab=0\:\mathrm{then}\:a=0\:\mathrm{or}\:b=0\:\left(\mathrm{or\:both}\:a=0\:\mathrm{and}\:b=0\right)[/tex]

so

[tex]x-4=0\quad \mathrm{or}\quad \:x-2=0\quad \mathrm{or}\quad \:x-5=0[/tex]

[tex]x =4, x=2, x = 5[/tex]

Thus, the zeros are:

[tex]x =4, x=2, x = 5[/tex]

It is clear that there are three zeros and all the zeros are distinct real numbers.

Therefore,

The function has three distinct real zeros.

Hence, option (B) is true.

Suppose that 4 ≤ f '(x) ≤ 5 for all values of x. What are the minimum and maximum possible values of f(4) − f(2)? ______≤ f(4) − f(2) ≤ ______

Answers

Answer:

[tex]8 \le f(4) - f(2) \le 10[/tex]

Step-by-step explanation:

Given

[tex]4 \le f'(x) \le 5[/tex]

Required

Determine the minimum and maximum value of f(4) - f(2)

This question will be answered using the following mean value theorem.

[tex]f'(x) = \frac{f(b) - f(a)}{b - a}[/tex]

In this case: [tex]b = 4[/tex] and [tex]a = 2[/tex]

So, we have:

[tex]f'(x) = \frac{f(4) - f(2)}{4 - 2}[/tex]

[tex]f'(x) = \frac{f(4) - f(2)}{2}[/tex]

Make f(4) - f(2), the subject:

[tex]f(4) -f(2) = 2 * f'(x)[/tex]

From the given range: [tex]4 \le f'(x) \le 5[/tex]

We have that; f'(x) is at minimum at 4

So, the minimum of f(4) - f(2) is:

[tex]f(4) -f(2) = 2 * 4[/tex]

[tex]f(4) -f(2) = 8[/tex]

We have that; f'(x) is at maximum at 5

So, the maximum of f(4) - f(2) is:

[tex]f(4) - f(2) = 2 * 5[/tex]

[tex]f(4) - f(2) = 10[/tex]

Hence, the minimum and maximum values can be expressed as:

[tex]8 \le f(4) - f(2) \le 10[/tex]

Answers

Answer:

D) The vectors point in opposite directions.

Step-by-step explanation:

see graph below

Given vectors u = (-2,1) and v =( 4, -2) represents the vectors point in opposite directions.

What is vectors?

"Vectors is a quantity which gives us both magnitude and direction of the given quantity."

According to the question,

Given vectors u(-2,1) and v(4,-2) represented on the graph.

From the graph we conclude that given vectors u and v

Does not form obtuse angle of approximately 93° , 96° or 127°.

The vector 'u(-2,1)' is in second quadrant and v(4,-2) is in fourth quadrant.

Second quadrant and fourth quadrant are in opposite direction.

Hence, we conclude the vectors point in opposite directions.

A line is drawn so that it passes through the points (-5,-3) and (-7,-5). What is the slope of the line?

Answers

Answer:

1

Step-by-step explanation:

The required slope of the line is 1 which passes through the points (-5, -3) and (-7, -5).

What is the slope of the line?

The slope of a line is defined as the change in the y-coordinate (the "rise") divided by the change in the x-coordinate (the "run").

To determine the slope of the line that passes through the points (-5, -3) and (-7, -5), we can use the formula:

Slope m = (y₂ - y₁)/(x₂ -x₁ )

Let

x₁ = -5, y₁ = -3

x₂ = -7, y₂ = -5

∵ Slope m = (y₂ - y₁)/(x₂ -x₁ )

Plugging in the coordinates of the two points, we get:

slope = (-5 - (-3)) / (-7 - (-5))

Simplifying this expression gives us:

slope = -2 / -2

Which simplifies to:

slope = 1

Therefore, the slope of the line that passes through the points (-5, -3) and (-7, -5) is 1.
