Answer:
Option B: 
Step-by-step explanation:
A function is said to be increasing if it has a slope greater than 0.
The function with the largest slope has the highest increasing rate.
Here, for the graph in option A, the function is decreasing with increasing 
. So, it has a negative slope.
We need to convert equation of option B into standard form and then determine its slope.
The standard form of a straight line is 
, where 
is the slope of the line and 
is the y-intercept.
Now, given function is:
Therefore, the slope is 2.
Option C:
Slope is given as,
Therefore, the slope is 1.
Option D:
Equation of a line with 
and as and 
intercepts is given as,
Here, 
and 
∴ 
Therefore, the slope is 
.
Hence, the largest slope is for option B and thereby the highest increasing rate.
The value of d in equation Q/R=8/d is 8R/Q.
Given an equation Q/R=8/d.
We are required to find the value of d in the given equation.
Equation is basically the relationship between two or more variables that are expressed in equal to form. The values that we enter is known as domain and the values that we get is known as range. It can be linear equation, quadratic equation, cubic equation.
The equation is :Q/R=8/d
We have to take d in right side of equal to sign and Q,R to the left side of right side of equal to sign.
d=8R/Q
Hence the value of d in equation Q/R=8/d is 8R/Q.

<em><u>The cost of production equation is:</u></em>
C = 10n + 20000
<em><u>Solution:</u></em>
<em><u>The equation representing the cost, C, of producing n tires at Royal Tires Co. can be written as:</u></em>
C = mn + f
Where,
C = cost
n = number of tires
f = company's fixed cost
<em><u>It costs $30,000 to produce 1,000 tires while it costs $50,000 to produce 3,000 tires</u></em>
Therefore,
30, 000 = m(1000) + f
50, 000 = m(3000) + f
Which is,
1000m + f = 30000 ------- eqn 1
3000m + f = 50000 ------- eqn 2
Subtract eqn 1 from eqn 2
3000m + f = 50000
1000m + f = 30000
( - ) -------------------
2000m = 20,000
m = 10
Substitute m = 10 in eqn 1
1000(10) + f = 30000
f = 30000 - 10000
f = 20,000
Thus the equation is:
C = 10n + 20000
Sum of the terms of the series is
Sn = n/2 ( a1+an )
we have n= 6 , a1= 17, an = 57
so Sn = 6/2 ( 17+57) = 3(74) = 222
