Answer:

For the problem we have:

Sam had 14 people at the party.

The party lasted for 4 hours.

He paid $2 for each person's skate rental and 3 for each person's entry ticket.

Suppose we want to know how much Sam spent on the party.

But we do not know if the $2 of the skate rental are per hour or per two hours, or in total, for example, if the amount is per hour, then the total amount for each skate is $2*4 = $8, so in the case that the rental depends on the time, we can not solve this problem because we do not have enough information.

If the $2 are fixed (do not depend on the time that the party lasted) then the fact that the party lasted for 4 hours does not matter.

We can calculate as 14 persons* ($2 + $3) each = 14*$5 = $70, then you can see that in this case the 4 hours data is not necessary

A rectangle is inscribed with its base on the x-axis and its upper corners on the parabola y=2−x2. What are the dimensions of su
Paul [167]

Answer:

Step-by-step explanation:

Given that a rectangle is inscribed with its base on the x-axis and its upper corners on the parabola

y=2-x^2

the parabola is open down with vertex at (0,2)

We can find that the rectangle also will be symmetrical about y axis.

Let the vertices on x axis by (p,0) and (-p,0)

Then other two vertices would be (p,2-p^2) (-p,2-p^2) because the vertices lie on the parabola and satisfy the parabola equation

Now width = 2-p^2

Area = l*w = 2(2p-p^3)

Use derivative test

I derivative = 2(2-3p^2)

II derivative = -12p

Equate I derivative to 0 and consider positive value only since we want maximum

p = \sqrt{\frac{2}{3} }

Thus width= \sqrt{\frac{2}{3} }

Length =2\sqrt{\frac{2}{3} }

Width = 2-2/3 = 4/3

Answer:

x = 8

FE = 54

Its Acute, Isosceles triangle

Step-by-step explanation:

Well you have to do this out of order and use some knowledge about questions, (It always helps.)

Lets do 12 first:

If this were a scalene triangle, you wouldn't be able to solve for it. Because no sides are equal and this isn't equilateral, because it only shows two equal angles. Therefore it is Isosceles.

Also, if this were a right triangle we would see the little square for an angle. It isn't obtuse because if you look at the triangle and its angles it isn't wider than the square (this only works on the ones that are to scale like this one) So again by elimination and some knowledge of the question we figure out that it is an acute scalene triangle

Now we try and find X. Because Angles F, and E are equal, we can make the two sides equal to each other and solve for x.

Add 24 on both sides

8x - 24 = 40

     +24  +24

Divide by 8 on both sides

8x/8 = 64/8

And Voilla

X = 8

Hope this helped! Ask me if you have any further questions!

Answer:

D.

Step-by-step explanation:

f(x) increases by 2 as x increases by 1 x value.

We know it isn't A since and x value plue 2 would not equal the y value.

But if you multiply each x-value by 2 you get f(x)
