Answer:
Step-by-step explanation:
Remember that the derivative tells us the slope of the tangent line at a given point.
So, we want to find the equation of the tangent line to f(x) at x=8.
We are given that f'(8) is -10.
In other words, the slope of the tangent line to f(x) at x=8 is -10.
We also know that f(8)=9. In other words, we have the point (8,9).
So, we can use the point-slope form to figure out the equation:
Substitute -10 for m and let (8,9) be (x₁, y₁). So:
Distribute the -10:
Add 9 to both sides:
And we're done!
Number of shirts a department store bought = 200
Cost price of 200 shirts = $5400
Cost price of 1 shirt :
Thus, the cost price of one shirt = $27
Price at which the department store sold each shirt = $30
Which means :
▪︎Cost price of shirt = $27
▪︎Selling price of shrit = $30
Since selling price is greater than cost price, there was a markup in the price of the shirts.
We know that :
Markup percentage in the price of the shirts :
Thus, the percentage of markup =
Therefore, the percentage of markup in the shirt's price =
Answer:
100
Step-by-step explanation:
103.37 and after rounding off to nearest tenth it becomes 100
Well let me solve it like this:
As we know the area is h(a+b)/2,
So what we do is:
<span>h (180/2) = 8100 </span>
<span>90h = 8100 </span>
<span>h = 90
</span>I hope this is easy to understand
