Hello from MrBillDoesMath!
Answer:
10.5 or 21/2
Discussion:
By "proximity: I thin the questions is to evaluate
(11 3/8) - (7/8) =
11 + (3/8) - (7/8) =
11 - (4/8) =
11 - (1/2) =
(22/2) - (1/2) =
21/2 = 10.5
Thank you,
MrB
A. Yes you are correct that the gradient at any point is 3/(3x-1). However at point P it would be 3/(3*2-1)=2/5
b. The gradient of the normal would therefore be -5/2
We can use the general formula of an equation to get y-ln(5)=-5/2 (x-2)
Now multiply both sides by 2 to get:
2y-2ln(5)=-5x+10
Now when it crosses the x axis we know that y=0 therefore:
5x=10+2ln(5)
Therefore:
x=2+2/5 ln(5) when y=0
You could find an estimate of this number to be 2.64 (3sf) but this might not be sufficient
Answer:
I think the answer is (-3,1)
To find the answer to this question, we need to find the common denominator for 3/5 and 2/3.
The easiest way to do this is to multiply the denominators by each other.
5*3=15
Now, all we have to do is multiply the numerators by what we multiplied the denominators by, to make it equal.
3*3=9
2*5=10
Now all we have to do is add.
9/15+10/15=19/15 or 1 and 4/15.
Hope this helps!
