Answer:

A(3,-8)= x1y1

B(7,6)= x2y2

here,

midpoint = (x1+x2/2,y1+y2/2)

= (3+7/2) (-8+6/2)

= (10/2,-2/2)

= (5,-1)

Step-by-step explanation:

by using midpoint formula

There are several ambiguities in your question upon which I feel disinclined to speculate. It cries out for an explanatory diagram:

For example (i.e. including but not only!):  

1. What is the essential distinction between a plane and a regular pyramid?

2. Does each of the two solids have all of its own edges equal, independently of the other solid? Or are the corresponding edges of the two solids equal? Or are all edges of both solids equal?

Answer:

$21600

Step-by-step explanation:

Net income is calculated by deducting all company expenses from its total revenue. Net income is given by the formula:

Net income = Revenue - cost of goods sold - operating expenses - tax.

But Gross margin = gross profit = Revenue - cost of goods sold. Hence:

Net income = Gross margin - operating expenses - tax.

Substituting gives:

Net income = $50000 - $23000 - $5400

Net income = $21600

Answer:

Either [tex]\displaystyle \frac{-1522}{\sqrt{41}}[/tex] (approximately [tex]-238[/tex]) or [tex]\displaystyle \frac{1522}{\sqrt{41}}[/tex] (approximately [tex]238[/tex].)

Step-by-step explanation:

Let [tex]a[/tex] denote the first term of this geometric series, and let [tex]r[/tex] denote the common ratio of this geometric series.

The first five terms of this series would be:

First equation:

[tex]a\, r^4 - a = 150[/tex].

Second equation:

[tex]a\, r^3 - a\, r = 48[/tex].

Rewrite and simplify the first equation.

[tex]\begin{aligned}& a\, r^4 - a \\ &= a\, \left(r^4 - 1\right)\\ &= a\, \left(r^2 - 1\right) \, \left(r^2 + 1\right) \end{aligned}[/tex].

Therefore, the first equation becomes:

[tex]a\, \left(r^2 - 1\right) \, \left(r^2 + 1\right) = 150[/tex]..

Similarly, rewrite and simplify the second equation:

[tex]\begin{aligned}&a\, r^3 - a\, r\\ &= a\, \left( r^3 - r\right) \\ &= a\, r\, \left(r^2 - 1\right) \end{aligned}[/tex].

Therefore, the second equation becomes:

[tex]a\, r\, \left(r^2 - 1\right) = 48[/tex].

Take the quotient between these two equations:

[tex]\begin{aligned}\frac{a\, \left(r^2 - 1\right) \, \left(r^2 + 1\right)}{a\cdot r\, \left(r^2 - 1\right)} = \frac{150}{48}\end{aligned}[/tex].

Simplify and solve for [tex]r[/tex]:

[tex]\displaystyle \frac{r^2+ 1}{r} = \frac{25}{8}[/tex].

[tex]8\, r^2 - 25\, r + 8 = 0[/tex].

Either [tex]\displaystyle r = \frac{25 - 3\, \sqrt{41}}{16}[/tex] or [tex]\displaystyle r = \frac{25 + 3\, \sqrt{41}}{16}[/tex].

Assume that [tex]\displaystyle r = \frac{25 - 3\, \sqrt{41}}{16}[/tex]. Substitute back to either of the two original equations to show that [tex]\displaystyle a = -\frac{497\, \sqrt{41}}{41} - 75[/tex].

Calculate the sum of the first five terms:

[tex]\begin{aligned} &a + a\cdot r + a\cdot r^2 + a\cdot r^3 + a \cdot r^4\\ &= -\frac{1522\sqrt{41}}{41} \approx -238\end{aligned}[/tex].

Similarly, assume that [tex]\displaystyle r = \frac{25 + 3\, \sqrt{41}}{16}[/tex]. Substitute back to either of the two original equations to show that [tex]\displaystyle a = \frac{497\, \sqrt{41}}{41} - 75[/tex].

Calculate the sum of the first five terms:

[tex]\begin{aligned} &a + a\cdot r + a\cdot r^2 + a\cdot r^3 + a \cdot r^4\\ &= \frac{1522\sqrt{41}}{41} \approx 238\end{aligned}[/tex].

Step-by-step explanation:

When f(x) = f(x - 4), 3x² = 3(x - 4)².

=> x² = (x - 4)², x = -(x - 4), 2x = 4, x = 2.

The x-value is 2.

Answer:

4.5

Step-by-step explanation:

that is

their rates =1/6, 1/3 respectively

total =1/2

if 1/2=9

1= 9/2

= 4.5

We want to find the rate at which Aaron and Ana work together, we will find that when working together they can paint 1 door in 2 hours.

We know that Aaron can paint a door in 6 hours and Ana can paint the same door in 3 hours. The rates are just defined as the number of doors painted over time, so we get:

When they work together the rates just add up, so we get:

R =   (1 door/ 6h) +  (1 door/ 3h) =  (1 door/ 6h) +  (2 door/ 6h)

  = (3 doors/6 hours) = (1 door/ 2 hours)

This means that, working together, they can paint 1 door in 2 hours.

Answer: 15(3+4)

Step-by-step explanation:

First, we want to find the GCF of these numbers

The greatest number they can both be divided by is 15

All of the possible factors are 1, 3, 5, 9, 15, and 15 is the highest

So 15 is the GCF

We then divide these numbers to get the equation

45/15=3

60/15=4

So the new equation would be (3+4)

We then add the GCF outside the parenthesis so you can distribute it in order to get the original numbers

So the distributive equation would be 15(3+4)

Answer 15(3+4)

Answer:

A horizontal line is an example of a functional relationship.

All functions have an independent variable.

All functions have a dependent variable (At least).

Step-by-step explanation:

By description, a relation is a purpose if each input condition has one and only one output value.

A function has at least a secondary variable and an autonomous variable. For instance, given a function:

Y=X

The secondary variable is "y" and the autonomous variable is "x".

The Field of the role is the collection of potential input values and the Range is the collection of potential output values,

Vertical lines have an irregular slope. Since the value of "x" never varies, an upward line is not an illustration of a functional relationship.

In the matter of Horizontal lines, for any x-value, you get the equivalent y-value. These are described as Constant functions.

Step-by-step explanation:

From the question we are told that

Altitude of Height 1.4miles

4miles west

a) From the question

[tex]f(x)=ax3+bx2+cx+d[/tex] on interval (-4,0)

The descent can be expressed in [tex]\triangle _x =-4,0[/tex]

therefore  initial points is (-4 , 1.4).

final co-ordinate is given by (0,0) as its landing

Mathematically solving in above  cubic equation

 [tex]0 = 0 + 0 + 0 + d \\[/tex]

[tex]d = 0[/tex]

[tex]1.4 = -64a + 16b -4c + d[/tex]

[tex]1 = -45.7a + 11.4b-2.9c+d[/tex]

Generally in this case Slope of tangent at point of descent is zero.assuming flight was initially straight before descent

     [tex]f'(x) = 3ax^2 + 2bx+c[/tex]

    [tex]f'(-4) = 48a -8b + c = 0[/tex]

    [tex]f'(0) = c = 0[/tex]

Mathematically solving above equations we have

[tex]a = \frac{1}{40} \ and \ b = \frac{3}{20}[/tex]

Therefore having found a and b the Cubic equation is given as

[tex]f(x) = \frac{1}{40}x^3 + \frac{3}{20}x^2[/tex]

b)descent at its greatest rate

[tex]f(x)=\frac{1.4}{40} x^3 + \frac{129}{20} x^2[/tex]

[tex]f(x)=\frac{1.4}{40} x^3 + \frac{129}{20} x^2[/tex]
