What is the range of the function on the graph

Answer:

I believe it's D.

Step-by-step explanation:

if you add 237 + 228 you get 455. 455 divide by 2 is 227.5 which doesn't make it even.

Slope = -6/5

Work is provided in the image attached.

The slope of the line passing through the given points is -6/5.

The slope of a line can be found using the formula: m = (y2 - y1) / (x2 - x1).

In this case, the coordinates of the two points are (-8, -6) and (-18, 6). Applying the formula, we have: m = (6 - (-6)) / (-18 - (-8)) = 12 / (-10) = -6/5.

Therefore, the slope of the line that passes through the points (-8, -6) and (-18, 6) is -6/5.

Answer:

Step-by-step explanation:

Given two parametric equations [tex]x(t)[/tex] and [tex]y(t)[/tex], the first derivative can be found using the following equation:

[tex]\frac{dy}{dx} = \frac{\frac{dy}{dt}}{\frac{dx}{dt}}[/tex]

In this problem, [tex]x(t) = 3e[/tex] and [tex]y(t) = 3^{3t} - 1[/tex]. Finding the derivative of each of these functions with respect to [tex]t[/tex] gives us the following:

[tex]\frac{dx}{dt} = 0[/tex]

[tex]\frac{dy}{dt} = 3^{3t + 1}\log{3}[/tex]

Because [tex]\frac{dx}{dt} = 0[/tex], that means the function is a vertical line and has an infinite first derivative.

Final answer:

The first derivative of the x-component is zero, and the first derivative of the y-component is 27. The second derivatives of both components are zero.

Explanation:

To find the first and second derivatives of the function defined by the parametric equation, we need to differentiate each component with respect to the parameter (in this case, t). Let's start with x = 3e, which is a constant, so its derivative is zero. Next, let's differentiate y = 3^3t - 1. The derivative of 3^3t with respect to t is (3^3)(1) = 27, and since the derivative of -1 with respect to t is 0, the y-component's derivative is 27.

Now, to find the second derivative, we differentiate the derivatives we found. The second derivative of x is still zero since the first derivative is zero. The second derivative of y (27) is also zero since it is a constant. Therefore, the first and second derivatives of the parametric equation are dx/dt = 0 and dy/dt = 27, respectively.

Answer:

$1.10

Step-by-step explanation:

We have been that Alex went to the grocery store and bought 5 avocados. He paid $10 and received $4.50 in change.

First of all, we will find amount paid for 5 avocados by subtracting $4.50 from $10.

[tex]\text{Amount paid for 5 avocados}=\$10-\$4.50[/tex]

[tex]\text{Amount paid for 5 avocados}=\$5.50[/tex]

Now, we will divide $5.50 by 5 to find cost of each avocado.

[tex]\text{Cost of each avocado}=\frac{\$5.50}{5}[/tex]

[tex]\text{Cost of each avocado}=\$1.10[/tex]

Therefore, the cost of each avocado is $1.10.

Answer:

The answer is y = 11.

Answer:

3 3/4 mls ink.

Step-by-step explanation:

2/3 of a box  corresponds to 2 1/2 mls of ink

So one box .............................. 2 1/2 / 2/3 = 5/2 / 2/3

= 5/2 * 3/2

= 15 / 4

=  3 3/4 mls ink.

It would take approximately 3.75 milliliters of ink to print off an entire box of paper. This is based on the given that 2.5 milliliters prints off 2/3 of a box and the conversion to a full box.

The question is asking about the amount of ink it will take to print an entire box of paper. We are given that a printer cartridge with 2.5 milliliters of ink will print off 2⁄3 of a box of paper. So, if 2.5 ml prints 2⁄3 of a box, we want to find out how much ink prints 1 full box. This is a simple ratio question.

Set up the ratios like this: 2.5 ml (ink) / (2⁄3 box) = X ml (ink) / (1 box) Simplifying this, you find that X = 2.5 ml / 2⁄3, which, when calculated, equals approximately 3.75 ml. This means it will take approximately 3.75 milliliters of ink to print off an entire box of paper.

Answer:

vertex = (4, - 25 )

Step-by-step explanation:

Given a quadratic function in standard form : f(x) = ax² + bx + c : a ≠ 0

The the x- coordinate of the vertex is

[tex]x_{V}[/tex] = - [tex]\frac{b}{2a}[/tex]

f(x) = x² - 8x - 9 ← is in standard form

with a = 1, b = - 8, thus

[tex]x_{V}[/tex] = - [tex]\frac{-8}{2}[/tex] = 4

Substitute x = 4 into f(x) for corresponding value of y

f(4) = 4² - 8(4) - 9 = 16 - 32 - 9 = - 25

vertex = (4, - 25 )

Answer:

vertex is (4,-25)

Step-by-step explanation:

[tex]f(x) = x^2 - 8x - 9[/tex]

To find out the vertex we use formula

[tex]x=\frac{-b}{2a}[/tex]

From the given f(x), the value of a=1, b=-8 and c=-9

Plug in the values in the formula

[tex]x=\frac{-(-8)}{2(1)}[/tex]

x=4

Now find the value of y

plug in 4 for x in f(x)

[tex]f(4) = 4^2 - 8(4)- 9=-25[/tex]

The value of y is -25

The vertex is (4,-25)

The number under the radical sign is called the radicand. ... the given square numbers, each product of square numbers is equal to what square ... are relatively prime -- and it will be impossible to divide n· n into m· m and get 2.

Step-by-step explanation:

Rational numbers are numbers that can be represented as a fraction of two integers. For [tex]\sqrt{76 + n}[/tex] and [tex]\sqrt{2n + 26}[/tex] to be rational, the smallest value of n is 5

Given that:

[tex]\sqrt{76 + n}[/tex] and [tex]\sqrt{2n + 26}[/tex] --- correct expressions

For both numbers to be rational, we should be able to represent the numbers as a fraction of two integers.

There are no straight ways to solve this, except trial by error.

When [tex]n = 1[/tex]

[tex]\sqrt{76 + n} = \sqrt{76 + 1} = \sqrt{77} = 8.77496.......[/tex]

The above is not rational

When [tex]n = 2[/tex]

[tex]\sqrt{76 + n} = \sqrt{76 + 2} = \sqrt{78} = 8.83176......[/tex]

The above is not rational

When [tex]n = 3[/tex]

[tex]\sqrt{76 + n} = \sqrt{76 + 3} = \sqrt{79} = 8.88819......[/tex]

The above is not rational

When [tex]n = 4[/tex]

[tex]\sqrt{76 + n} = \sqrt{76 + 4} = \sqrt{80} = 8.944271......[/tex]

The above is not rational

When [tex]n = 5[/tex]

[tex]\sqrt{76 + n} = \sqrt{76 + 5} = \sqrt{81} = 9[/tex]

The above is rational

So, we try [tex]n = 5[/tex] for the second expression

[tex]\sqrt{2n + 26} = \sqrt{2\times 5 + 26} = \sqrt{10 + 26}=\sqrt{36}= 6[/tex]

The above is also rational

Hence, the smallest value of n that makes each of the expression rational is [tex]n = 5[/tex]

Answer: We start with 6 reams of copy paper and 8 teachers.

a) if we distribute the paper equally between all the teachers, then each teacher receive 6/8  (here we are dividing the total number of reams by the number of people that we are are splitting it). but 6/8 is less than one, so we must open the reams in order to split them.

b) If there were twice as many reams of paper, then we will have 2*6 = 12 reams of paper, and if there where half the number of teachers, then we have 8/2 = 4 teachers.

Doing the same procedure as before, we have 12 teams for 4 teachers, then each teacher has 12/4 = 3 reams

before, each teacher received 6/8 reams, and now, each one receive 3.

if we want to know the change, we need to see the difference between these numbers, so 3 - 6/8 =  3*8/8 - 6/8

notice that i am multiplying the 3 by 8/8, this is one, but  this way i can have the same denominator in both numbers.

24/8 - 6/8 = 18/8 = 9/4 = 8/4 + 1/4 = 2 + 1/4

so each teacher receive 2 + 1/4 reams than before.

Step-by-step explanation:

The equation of the least squares regression line is ŷ = -173.51 + 4.83x.

The equation of the least squares regression line for a data set is represented as ŷ = a + bx, where a is the y-intercept and b is the slope of the line. To calculate the values of a and b, you minimize the sum of squared errors (SSE). Using calculus, you can determine the values that make SSE a minimum. In this case, the equation of the least squares regression line is ŷ = -173.51 + 4.83x.
