1 answer:
Answer:
The average cost of each tie is $56.350
Step-by-step explanation:
We are given that a men tie buyer plans to promote a $39.99 tie. Consequently, the buyer purchases 450 ties
So, Cost of 450 ties =
An order for 100 ties that cost $20.00 each
Cost of 100 ties =
Total cost price = 17995.5+2000 = 19995.5
Let the selling price of 1 tie be x
Total ties = 450+100 = 550
So, SP of 550 ties =550x
Now we are given that markup is 55%
So, Profit % = 55%
So,
Substitute the values
Hence The average cost of each tie is $56.350

I don't know for sure, but I think there might be an error in the way you copied your function. In all of my dealings with these types of problems, I have learned the formula to be h(t) = 15 + 10t - 16t^2. Notice the plus in front of the "10t". This is due to the fact that if he pushes off of the overhang he would have an upward force of 10 feet per second as soon as his feet left the ground. The only thing pulling him back to Earth is gravity, modeled by the "-16t^2". This is derived from a bit of slightly advanced physics involving the gravitational constant, but let's work under my formula for a second...
Either way, we will wind up using the Quadratic Formula (or possibly factoring if the numbers are easy enough to work with). So let's start.
h(t)= 15 +10t - 16t^2
In order to use the QF or factoring I will need to make h(t)=0. Simply done by:
0= 15 +10t -16t^2
Looking at the numbers, I'd prefer to use the QF so here it is:
I know that my answer will need to be positive since you can't have a negative value when dealing with time, so I will eliminate the positive sign from the "+or-" part leaving me with:
And I know that a= -16, b= 10, and c=15. So all that's left to do is substitute and solve.
There's a decent amount of math that would be difficult and sloppy for me to do over the computer, but all you need to do is solve the rest of the equation and you would get your answer.
Exact answer:
or rounded answer: ≈1.31 seconds.
Hope this helps!

Answer:
18.7
Step-by-step explanation:
The Law of Cosines is , where c is the unknown side length of a triangle, a and b are the remaining two side lengths, and C is the angle opposite to side c. To answer this question just plug in the known values:
Simplify:
m≈18.665...
When rounded to the nearest tenth, m=18.7
For this case we have the following function:
The first thing you should do is graph the function to see the behavior.
When observing the graph (in the attached image) we observe that the following point belongs to the graph:
To prove it, let's evaluate the point in the function:
The equation is fulfilled and therefore the point belongs to the graph.
Answer:
(6.2, 7.4)
