Answer:

see below

Step-by-step explanation:

We can't help you with using your tools, but we can show you what the solution will look like when you're finished.

If you need to find points on the curve, you can substitute x=0, 1, 2, 3 into the function to see what they are. For example, f(0) = 0²-3 = -3; f(1) = 1² -3 = -2; and so on. The curve is symmetrical about the y-axis, so the points on the left are mirror images of the points on the right.

We fill in the following formula:
$\frac{part}{total} \times 100\%$

So in this case we get
$\frac{17}{20} \times 100\% = 85\%$

Therefore the answer is 85%

You have been asked to design a rectangular box with a square base and an open top. The volume of the box must be 2916cm3. Deter

aleksklad [387]

Answer:

x = 18 cm

y = 9 cm

Step-by-step explanation:

An open-top box will have minimum surface area when it is in the shape of half a cube. The whole cube would have volume 2×2916 = 5832 cm³, so its side length would be ∛5832 cm = 18 cm.

The dimensions of the box are x = 18 cm; y = 9 cm.

The surface area is x^2 +4xy, where y = 2916/x^2. That is, the surface area is ...

S = x^2 +11664/x

Setting the derivative to zero, we find ...

dS/dx = 0 = 2x -11664/x^2

x^3 = 5832 . . . . . . . . may look familiar

x = ∛5832 = 18

y = 2916/18^2 = 9

The number f of miles a helicopter is from its destination x minutes after takeoff is given by f (x)=40-2x. The number f of mile

nevsk [136]

Answer:

Step-by-step explanation:

Function 'f' represents the number of miles (y-values) covered by the helicopter in 'x' (x-values) minutes.

f(x) = 40 - 2x

For x = 0,

f(x) = 40 miles

For f(x) = 0,

0 = 40 - 2x

x = 20 minutes

This shows that helicopter traveled 40 miles in 20 minutes.

Similarly, given graph shows distance covered by the jet on y-axis and duration of flight on x-axis.

For x = 0,

f(x) = 500 miles

For f(x) = 0,

x = 100 minutes

Commercial jet traveled 500 miles in 100 minutes.
