Answer:
$960
Step-by-step explanation:
110% = $880
10% = $80
120% = $960
Well, from those 560, 200 are from her salary, and the rest is commissions from sales, so.... 360 is the 5.5% she's got, now, if we take "x" to be the 100% for the sales, then
solve for "x".
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:
So A, D, and G.
Step-by-step explanation:
When x = 2, both expressions have a value of 18. True
The expressions are only equivalent for x = 4 and x = 6. False
The expressions are only equivalent when evaluated with even values. False
The expressions have equivalent values for any value of x. True
The expressions should have been evaluated with one odd value and one even value. false
When x = 0, the first expression has a value of 4 and the second expression has a value of 5. False
The expressions have equivalent values if x = 8. True
