The reflection of the point (1,6) across the x-axis is (1,-6).

A coordinate plane is a 2D plane that is formed by the intersection of two perpendicular lines known as the x-axis and y-axis. A coordinate system in geometry is a method for determining the positions of the points by using one or more numbers or coordinates.

A figure's mirror image in the axis or plane of reflection is its image by reflection.

Given that the coordinate is (1,6). The reflection of the coordinates across the x-axis will be,

R(x₁ , y₁) ⇒ R(x₁,-y₁)

R(1,6) ⇒ R( 1,-6)

Answer:

Step-by-step explanation:

You can easily find the slope by using two points. Let’s use (13, 11) and (14, 6)

We look at the slope equation as: y2 - y1 divided by x2 and x1.

13 = x1 11= y1 and 14= x2 6=y2

Plug in: 6-11/14-13 and solve

Answer: -5

Hope I made sense :)

Answer:

Slope (m) = -5

Step-by-step explanation:

*If all the given four points are on a straight line then; the slope derived from first two points should be equal to the slope derived from the next to points.

Let's verify this ...

For the first two points:

Slope (m) = change in y ÷ change in x = [tex]\frac{6 - 11}{14 - 13} = \frac{-5}{1} = -5[/tex]

For the next two points:

m = [tex]\frac{-4 - 1}{16 - 15} = -5[/tex]

*Proved ∴ points (13,11) , (14,6) , (15, 1) and (16,-4) are on the same line.

Taking another point (x,y) on the line and point (13,11);

m = [tex]\frac{y - 11}{x - 13} = -5[/tex]

y = -5x + 65 + 11

y = -5x + 76

Answer:

y=-1/10 x - 41/10

Step-by-step explanation:

slope: y2-y1 / x2-x1 = -5-(-4) /  9-(-1) = -1/10

y= -1/10 x +b, substitute (-1,-4) to solve b

-4=-1/10 (-1) +b

Multiplication is the process of multiplying, therefore, adding a number to itself for the number of times stated. The value of 25×8.5 is less than 250. The correct option is B.

Multiplication is the process of multiplying, therefore, adding a number to itself for the number of times stated. For example, 3 × 4 means 3 is added to itself 4 times, and vice versa for the other number.

The value of 25×8.5 is needed to be calculated in order to know if the product is more than 250 or not. Therefore, the value of the 25×8.5 can be calculated as,

25×8.5

= 25 × (85/10)

= 2125/10

= 212.5

Since the value of the product of 25 and 8.5 is 212.5 which is less than 250. It can be calculated that the number is smaller than 250.

Hence, the value of 25×8.5 is less than 250.

Step-by-step explanation:

Answer:

[tex]-\frac{1}{2} (x - 1)^2 + 1[/tex]

Explanation:

Since it is flipped and now extending to negative infinity, we make [tex]x^2[/tex] negative, so it is [tex]-x^2[/tex].

Lastly, there are a few shifts, it is shifted right once and up once.

To shift it right once, you would subtract a 1 from x directly: [tex]-(x - 1)^2[/tex]

To shift it up once, you would add 1 to the entire equation: [tex]-(x - 1)^2 + 1[/tex]

To account for the stretching, it would be: [tex]-\frac{1}{2} (x - 1)^2 + 1[/tex]

Answer: The population after 3 hours is 13.9 mill.

Step-by-step explanation:

When we have an exponential with:

A  = initial population.

r = constant relative growth rate:

t = time.

The function that models this is:

P(t) = A*e^(k*t)

In this case we know that:

A = 3.9 mill.

r = 0.4225 1.

Then the function that models the population of this yeast cell is:

P(t) = (3.9 mill)*e^(0.4225*t)

where t represents the time in hours.

Then if we want to know the population after 3 hours, we should replace t by 3.

P(3) = (3.9 mill)*e^(0.4225*3) = 13.85 mill.

And we want to round our answer to one decimal place, then we must look at the second decimal place, we can see that is a 5, so we should round up.

The population after 3 hours is 13.9 mill.

The exponential function is often used to model the growth or decay of a population

The population size of the yeast cell after 3 hours is 7.9 million

The given parameters are:

[tex]\mathbf{a = 3.9m}[/tex] --- initial number of cells

[tex]\mathbf{r = 0.4225/hr}[/tex] --- rate

The nth term of an exponential function is:

[tex]\mathbf{f(n) = a(1 + r)^{n-1}}[/tex]

After 3 hours; n = 3

So, we have:

[tex]\mathbf{f(3) = a(1 + r)^{3-1}}[/tex]

Substitute values for a and r

[tex]\mathbf{f(3) = 3.9(1 + 0.4225)^{3-1}}[/tex]

[tex]\mathbf{f(3) = 3.9(1 + 0.4225)^{2}}[/tex]

[tex]\mathbf{f(3) = 3.9 \times (1.4225)^{2}}[/tex]

[tex]\mathbf{f(3) = 7.9}[/tex]

Hence, the population size of the yeast cell after 3 hours is 7.9 million
