The time required for a certain chemical reaction is related to the amount of catalyst present during the reaction.The domain of the relation is the number of grams of catalyst,and the range is the number of seconds required for a fixed amount of the chemical to react.The following relation is the data from several reactions:[(2,180),(2.5,6),(2.7,0.05),(2.9,0.001),(3.0,6),(3.1,6)(3.1,15)(3.2,37),(3.3,176)}.
A. Is the relation a function?
B. If the domain and range were interchanged,would the relation be a function?Explain.
"Relation is a function if the terms in domain corresponds a unique value in range"
A). Given relation is a function.
B). Interchanged relation will not be a function.
A). From the given ordered pairs, x-coordinate represents the term of Domain and y- coordinate represents the Range.
We find each term of domain is associated with a unique term in range.
Therefore, relation is a one-to-one function.
B). If the terms in range and domain were interchanged, one term 6 of domain relates with two different values of range,
x = 6, y = 2.5
x= 6, y = 3
Since, a term of domain can't have two different values in range,
Therefore, interchanged relation will not be a function.

if the area of an equilateral triangle is 9root3 cm square find its side
Answer:
6 cms.
Step-by-step explanation:
If the side of an equilateral triangle is 2x cm then its height is √3x and its base is 2x.
Area = 1/2 * base * height
9√3 = 1/2 * 2x * √3x
9√3 = x * √3x
9 = x^2
x = 3
So length of each side = 2*3 = 6.
x = 9

How do you find the solutions to a system of equations involving quadratic functions and other functions?
How do quadratic functions compare to linear and exponential functions?
Answer:
1. How to Solve using Algebra
Make both equations into "y =" format.
Set them equal to each other.
Simplify into "= 0" format (like a standard Quadratic Equation)
Solve the Quadratic Equation!
Use the linear equation to calculate matching "y" values, so we get (x,y) points as answers.
Algebraic method is more easy to do
2. linear functions have constant first differences. quadratic functions have constant second differences. exponential functions have a constant ratio.

what would be 0.93 repeating as a fraction in simplest form
Answer:
First, set x equal to .93
x=.939393939393...
Then, since the repeating is by two digits, let's multiply x by 100
This would make 100x=93.9393939393...
Now, we can subtract 100x−x
This would leave us with 99x=93 because the repeating digits cancel out.
This looks much easier now right?
Just divide the 99 and isolate the x to get x=9399
Get the simplified fraction, and the final answer is x=3133

Find m
Find m
Answer:
x = 37
m∠a = 104°
m∠b = 76
Step-by-step explanation:
Two supplementary angles will add up to 180 degrees. We can create an equation and solve for x.
3x - 7 + 2x + 2 = 180
~Combine like terms
5x - 5 = 180
~Add 5 to both sides
5x = 185
~Divide 5 to both sides
x = 37
~Find the measure of angle A
3(37) - 7
104
~Find the measure of angle B

Answer:
400 miles
Step-by-step explanation:
the equation could be :
90 + 0.80 n = 50 + 0.90 n , n for Numbers of miles.
90 + 0.80 n = 50 + 0.90 n
90-50 = 0.90 n - 0.80 n
40 = 0.10 n
n = 40/(0.10)
n = 400
Answer:
400 miles
Step-by-step explanation:
Define the variables:
Let x = number of miles driven
Let y = total cost of rental
Company A
Given:
Charge to rent the truck is $90 a day plus $0.80 per mile.⇒ y = 90 + 0.8x
Company B
Given:
Charge to rent the truck is $50 a day plus $0.90 per mile.⇒ y = 50 + 0.9x
To find the number of miles for which Company A and Company B charge the same amount, substitute the equation for Company A into the equation for Company B and solve for x:
⇒ 90 + 0.8x = 50 + 0.9x
⇒ 90 + 0.8x - 50 = 50 + 0.9x - 50
⇒ 40 + 0.8x = 0.9x
⇒ 40 + 0.8x - 0.8x = 0.9x - 0.8x
⇒ 40 = 0.1x
⇒ 40 ÷ 0.1 = 0.1x ÷ 0.1
⇒ 400 = x
Therefore, the number of miles for which the rental costs are the same from either company is 400 miles.
To find the cost, substitute x = 400 into one of the equations:
⇒ y = 90 + 0.8(400)
⇒ y = 90 + 320
⇒ y = 410
Therefore, the daily cost from both companies for 400 miles would be $410.

Calculate the slope of the line containing the points (6,-4) and (-1,-4).
Answer:
Step-by-step explanation:
(x₁ , y₁) = (6, -4) & (x₂ , y₂) =(-1 , -4)
In these two points, there is no change in y-coordinates. So, the line is parallel to x-axis.
Slope of line parallel to x-axis = 0

Answer:
(7.5, 12)Step-by-step explanation:
The solution of a linear system is the intersection of the lines.
We can see the lines A and B intersect at the point (7.5, 12) which is the solution.
See attached for better visualization.
Answer:
(7.5,12.5)
Step-by-step explanation:
See the intersected point is almost situated at the middle of 10 and 15 .Hence its 12.5 on y.And the point is situated in the middle of 7 and 8 .Hence its 7.5 on x.There is more than one (1) plane that can go through three collinear points. true or false?
