A cone-shaped hole is drilled into a solid cube of metal as shown. If the cube has sides of length 7 cm, what is the volume of t
aivan3 [116]
This problem really should have the image attached, as we are not quite sure what the radius of the cone is, nor are we sure about how deeply the cone-shaped hole is bored into the cube.  When I did this, I just assumed that the radius of the cone was half the length of the cube which is 3.5, and I assumed that the height of the cone was the same as the height of the cube which is 7. So the volume for the cube itself is 7*7*7=343. Now we have to subtract from that the volume of the cube, which has a formula of V= \frac{1}{3}  \pi  r^{2} h
If we fill in those values I'm assuming to be accurate, our formula then looks like this:
V= \frac{1}{3}(3.14)( 3.5^{2} )(7)
which equals 89.752   If we subtract the volume of the cone from the volume of the cube, we will get that volume of what's left is V=253.2 cm^{3}

A right angle is formed by two rays
serg [7]

Answer:

Vertex.

You go to the doctor and he injects you with 13 milligrams of radioactive dye. After 12 minutes, 4.75 milligrams of dye remain i
photoshop1234 [79]

Answer:

Step-by-step explanation:

You need to find the model for this situation using the points given. If you are given 13 mg immediately, the coordinate point for that is (0, 13), where the x coordinate is the time in minutes and the y coordinate is the amount of dye in mg.

If after 12 minutes, 4.75 mg remain, the coordinate point for that is (12, 4.75). Just so you know, the time unit always goes in for x, never for y.

Now that we have these coordinates we are going to use them as a system and find the model. Begin with the point (0, 13) in

A=a(b)^t where A is the amount left in the body, a is the initial amount injected, b is the rate at which it decays, and t is the time in minutes. Plug in the first set of coordinates:

13=a(b)^0 and since anything raised to the power of 0 is equal to 1, we have

13 = a. Now we can use that and write another equation with the other set of coordinates to solve for b:

4.75=13(b)^{12} and divide both sides by 13 (don't round anything yet) to get

.3653846154 = b¹². Now take the 12th root of both sides (you need a scientific calculator for this) to get that

b = .9195228407  Yikes.

Now for the model, using the fact that a = 13 and b = .9195228407:

A=13(.9195228407)^t  

We are told that the amount that we are allowed to leave with still remaining in our system cannot be more than 2 mg, so we sub in a 2 for A:

2=13(.9195228407)^t and begin by dividing away 13 to get

.1538461538=.9195228407^t  Take the natural log of both sides, which allows us to bring the t out front:

ln(.1538461538) = t ln(.9195228407) and finally divide by ln(.9195228407) to get

t = 22.3 minutes
