find the equation of the line containing the points shown
Answer:
y= 6x - 22
Step-by-step explanation:
(4,2) and (5,8)
m= (y2-y1)/(x2-x1)
m= (8-2)/(5-4)
m= 6
y-y1= m(x-x1)
y-2= 6(x-4)
y-2= 6x-24
y= 6x - 22

Describe how an electromagnetic wave carries energy from place to place. Your description should
include the terms electric field, magnetic field, and perpendicular.
Answer: Also according to Faraday's law of electromagnetic induction, changing magnetic field will create an electric field perpendicular to it's direction.
... That is why in an electromagnetic wave, electric and magnetic fields promote each other in directions perpendicular to themselves.
So they are perpendicular
Step-by-step explanation:

Answer:
Option B. x = 1 and x ≈ 4.2
Step-by-step explanation:
From the question given above, we can see that the graph represents two equation i.e a quadratic and a linear equation.
The solution of such graph as given in the question above can be obtained by simply taking the values of where both equation intercept on the x–axis.
From the graph, the two equation intercept at 1 and 4.2 on the x–axis.
Therefore, the solutions to the equation are:
x = 1 and x ≈ 4.2

first derivative of b/x
Answer:
[tex]\frac{dy}{dx} = -\frac{b}{x^2}[/tex]
Step-by-step explanation:
Given
[tex]\frac{b}{x}[/tex]
Required
Determine the first derivative
Rewrite the expression as:
[tex]y =\frac{b}{x}[/tex]
Apply law of indices
[tex]y =bx^{-1}[/tex]
An equation with the form
[tex]y = ax^n[/tex]
has the derivative:
[tex]\frac{dy}{dx} = nax^{n-1}[/tex]
So, the derivative of [tex]y =bx^{-1}[/tex] is
[tex]\frac{dy}{dx} = -1 * bx^{-1-1}[/tex]
[tex]\frac{dy}{dx} = -bx^{-2}[/tex]
[tex]\frac{dy}{dx} = -\frac{b}{x^2}[/tex]
Please give the right answer and show work if possible
Answer:
Height: 6.7 Length: 22
Step-by-step explanation:
Use Soh (sin(angle)=[tex]\frac{opposite}{hypotenuse}[/tex]) Cah (cos(angle)=[tex]\frac{adjacent}{hypotenuse}[/tex]) Toa (tan(angle)=[tex]\frac{opposite}{adjacent}[/tex])
Height:
You'd use sin so the equation is sin17=x/23 which is equal to (rounded) 6.7
Length:
You'd use cos so the equation is cos17=y/23 which is equal to (rounded) 22
*You always need to use a calculator when using sin, cos, and tan*
*SohCahToa is an easy way to remember the equations!*

the directions are : The table shows a proportional relationship between x and y. What is the unit rate of y per x.
Answer:
4
Step-by-step explanation:
To find the unit rate you can pick any row and do y divided by x
For example, x = 3 and y = 12 so you can do 12 / 3 = 4.
You could also use x = 5 and y = 20, so it would be 20 / 5 = 5

A man earns $3580 per month and spends 65% of it. How many does he save
every month?
$2327
$2237
$1523
$1253
Other:
Answer:
$1253
Step-by-step explanation:
65% of $3580=$2327 spent
$3580-$2327=$1253 saved
Answer:
1253.
Step-by-step explanation:
65% of 3580 is 2327.
3580-2327=1253.
try to graph y=0.4 x
Answer: y = 0.4x in desmos
Step-by-step explanation:
Answer:
Not applicable.
Step-by-step explanation:
You could use Desmos as another person answered. However, if you are graphing by hand, simply choose two points and draw a straight line between them.
For example, you could pick x = 0 and x = 1. This gives you the two points (0, 0) and (1, 0.4)
Plot those two points and use a straight edge to draw a line between the two.
In case you are having trouble plotting (1, 0.4) since it is a decimal, try setting x = 5, you will get (5, 2) which should be much easier to graph.

Which of the following illustrates how to find the difference of 4h^5k and -7hk^5
(4-7) h^5k
Not possible
(4+7) h^5 k^5
(4+7) h^5-1 k^1-5
Answer:
Not possible
Step-by-step explanation:
Which of the following illustrates how to find the difference of 4h^5k and -7hk^5
Takig the difference
4h^5k - (-7hk^5)
= 4h^5k +7hk^5
Collect the like terms
= hk(4h^4+7k^5)
Hence the difference is not possible

If 4x- 7 = 2x, then 2x = ?
If [tex]4x-7=2x[/tex], then [tex]2x=7[/tex].
Hope this helps.
Answer:
7
Step-by-step explanation:
We solve for x first.
So: 4x - 7 = 2x
Subtract 2x from both sides: 4x - 2x - 7 = 2x - 2x
2x - 7 = 0
Add 7 to both sides: 2x - 7 + 7 = 0 + 7
2x = 7
Divide by 2: [tex]\frac{2x}{2}[/tex] = [tex]\frac{7}{2}[/tex]
x = [tex]\frac{7}{2}[/tex]
Now, we substitute x for [tex]\frac{7}{2}[/tex] like this:
2 ( [tex]\frac{7}{2}[/tex]) = 7
Simplify Rewrite the expression in the form x ^ n X^ 2 * x ^ - 12 =
Step-by-step explanation:
Given
[tex] = {x}^{2} \times {x}^{ - 12 } \\ = {x}^{2 - 12} \\ = {x}^{ - 10} [/tex]

A party mix is made by adding nuts that sell for $2.50 per kg to a cereal mixture that sells for $1 per kg. How much of each should be added to obtain 40 kg if a mix that will sell for $1.30 per kg?
Answer:
40kg
Step-by-step explanation:
x + y = 60, y = 60 - x
x(2.50) + y(1) = 60(1.50)
Substitute:
2.50 x + 60 - x = 90
1.50x = 30
x = 20 kg
y = 40 kg
The base of a parallelogram is 1.4 feet long and the height is 0.32feet. What is the area of the parallelogram
Step-by-step explanation:
In a parallelogram
base (b) = 1.4 feet
height (h) = 0.32 feet
Now
Area of the parallelogram
= b * h
= 1.4 * 0.32
= 0.448 feet²
