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

What is the 5 ^ (th) term in the sequence ?
Answer:
the answer is -16
Step-by-step explanation:
n= 5 so 5 - 1 = 4 so it's -1(2)^4 right
2^4 is equal to 16 and then -1(16) = -16
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

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]

The ramp shown below is used to load heavy items into a moving van.
What is the measure of angle x?
Answer:
x = 18 degrees
Step-by-step explanation:
We are given 72 degrees. The box on the bottom left of the ramp is at a 90 degree angle. Given that this triangle will add up to 180 degrees no matter what we add the two given degrees; 72 + 90 = 162. Now we subtract; 180 - 162 = 18 degrees.
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

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

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
