Answer 1

Answer:

a)

d)

Step-by-step explanation:

It's easiest to reduce each statement to its simplest form for comparison

Our test statement can be reduced by combining like terms

16x - 12 -24x + 4 = -8x - 8

this becomes our new gold standard

a) 4 + 16x - 12(1 + 2x)

apply the distributive property by multiplying terms in parenthesis by -12

4 + 16x - 12 - 24x

combine terms

-8x - 8     Yeaah, We have a winner as it exactly matches our gold standard.

b) 40x - 16 is already in simplest terms and does NOT match the gold standard.

c) 16x - 24x - 4 + 12

has the same cardinal values as the original, but differing signs, reducing gives -8x + 8

Not quite the same as a plus sign occurs where a negative exists in our gold standard.

d) -8x - 8  is already in simplest terms and exactly matches our gold standard. Yeah!

e) 10(1.6x - 1.2 - 2.4x + 4)

apply distributive property by multiplying each term in parenthesis by 10

16x - 12 - 24x + 40

combine like terms

-8x + 28 does NOT match our gold standard

f(t)= 102,000/1+4400e^-t

Answers

Answer:

Beginning (t=0) population with flu is 23.

After 4 weeks, population with flu is 1250.

After an infinite amount of weeks, the population witf flu is 102000

Step-by-step explanation:

First question asks you to replace t with 0 because it says beginning.

102000/(1+4400e^-0)=102000/(1+4400)=102000/4401=23.17655 approximately. To nearest whole number this is 23.

After 4 weeks means we replace t with 4:

102000/(1+4400e^-4)

Calculator time:

1250.17142 which to nearest whole number is 1250

If t is super large, then e^-t is super close to 0.

So the limiting number is

102000/(1+4400×0)=102000/1=102000

Find a point on the line and the line's slope.
y+3=4(x+1)
point on the line: ?
slope:?

Answers

Answer:

The slope is 4 and a point on the line is (-1,-3)

Step-by-step explanation:

Point slope form is

y-y1 =m(x-x1)

where m is the slope and (x1,y1) is a point on the line

y+3=4(x+1)

y-  -3=4(x-  -1)

The slope is 4 and a point on the line is (-1,-3)

The vertex form of the equation of a vertical parabola is given by , where (h, k) is the vertex of the parabola and the absolute value of p is the distance from the vertex to the focus, which is also the distance from the vertex to the directrix. You will use the GeoGebra geometry tool to create a vertical parabola and write the vertex form of its equation. Open GeoGebra, and complete each step below. If you need help, follow these instructions for using GeoGebra. Mark the focus of the parabola you are going to create at F(6, 4). Draw a horizontal line that is 6 units below the focus. This line will be the directrix of your parabola. What is the equation of the line?

To practice writing the equations of vertical parabolas, write the equations of these parabolas in vertex form:

focus at (-5, -3), and directrix y = -6
focus at (10, -4), and directrix y = 6.

Answers

Answer:

Step-by-step explanation:

Focus: (6,4)

Directrix lies 6 units below the focus, so the parabola opens upwards and focal length p = 6/2 = 3.

The equation of the directrix is y = -2.

The vertex is halfway between focus and directrix, at (6,1).

Equation of the parabola:

y = (1/(4p))(x-6)²+1 = (1/12)(x-6)²+1

The equation of the parabola is [tex]y = \frac{1}{12}(x - 6)^2 + 1[/tex]

What are parabolas?

Parabolas are used to represent a quadratic equation in the vertex form

The given parameters are:

Focus = (6,4)

Directrix (x) = 6 units below the focus,

Start by calculating the focal length (p)

[tex]p = \frac x2[/tex]

This gives

[tex]p = \frac 62[/tex]

[tex]p = 3[/tex]

Next, calculate the vertex as follows:

[tex](h,k) = (6,2/2)[/tex]

Simplify

[tex](h,k) = (6,1)[/tex]

The equation of the parabola is then calculated a:

[tex]y = \frac{1}{4p}(x - h)^2 + k[/tex]

So, we have:

[tex]y = \frac{1}{4*3}(x - 6)^2 + 1[/tex]

Simplify

[tex]y = \frac{1}{12}(x - 6)^2 + 1[/tex]

Hence, the equation of the parabola is [tex]y = \frac{1}{12}(x - 6)^2 + 1[/tex]
