The equation D=13/v shows that the density of a particular substance equals a mass of 13 grams divided by the volume of the substance. What happens to the density as the volume approaches 0?The density approaches infinity.
The density approaches 0.
The density approaches 1.
The density approaches 13.

Answers

For this case we have the following equation:
$D = (13)/(v)$
Where,
D: the density of a particular substance
v: the volume of the substance
When replacing v = 0 in the given equation we have:
$D = (13)/(0)$
$D = \infty$
This means that as the function acquires values very close to zero, the density acquires a very large value.
Answer:
as the volume approaches 0:
The density approaches infinity.
option 1

As the volume approaches 0,
The density approaches infinity

The graph of the equation is a hyperbola with the asymptote at v = 0. This means that when the value of v is very close to 0, the value of the density is very large.

A spinner and 6 cards are shown below: A spinner with 3 equal sectors is shown in the figure. The colors Green, Blue, and Red are marked on it. The arrow points at the green color. Six cards are shown on the right side. The colors Purple, Green, Red, Yellow, Blue, and Pink are marked on them. Jordan spins the spinner and picks up a card without looking. What is the probability that the spinner stops at green and a yellow card is selected? 1 over 36 1 over 18 1 over 6 1 over 3

Answers

This is a case of joint probability: you want to know what the odds are of this event AND that event occurring. For a joint probability, the formula is usually given as:

P(A and B)=P(A)*P(B)

where P(A) is the probability of event A happening, P(B) is the probability of event B happening, and P(A and B) is the probability of both happening.

For this problem, let's say that event A is the probability that the spinner stops at the green color. Since the spinner has 3 colors and they have equal area (sector) occupied in the circle, each color has the same chance, 1/3 chance of being picked. Thus, there's a 1/3 chance of the spinner stopping at the green color so P(A)=1/3.

Event B is the probability of Jordan picking up the yellow card. There are six possible colors to pick and since Jordan picked up the card without peeking, each color has an equal chance to be picked. Thus, there's a 1/6 chance that the yellow card will be selected so P(B)=1/6.

Using the formula, we can then calculate P(A and B), the probability that the spinner stops at green and a yellow card is selected:

P(A and B)=P(A)*P(B)=1/3*1/6=1/18

Answer: the answer is 1/18, got it right on the test

Find the value of f(5) for the function
f(a)=5(a+1)-6

Answers

Answer:

To find the value of f(5) for the given function f(a) = 5(a + 1) - 6, you simply need to substitute the value a = 5 into the function and then solve for f(5).

Step-by-step explanation:

Given the function:

f(a) = 5(a + 1) - 6

To find f(5), you need to substitute the value a = 5 into the function.

Start with the original function:

f(a) = 5(a + 1) - 6

Replace 'a' with 5:

f(5) = 5(5 + 1) - 6

Simplify the expression inside the parentheses:

f(5) = 5(6) - 6

Now, perform the multiplication:

f(5) = 30 - 6

Finally, subtract 6 from 30:

f(5) = 24

So, the value of the function f(5) is 24. This means that when the input value is 5, the function evaluates to 24.

hope this helps you!

Can you solve 2^x=e^(x+2)

Answers

Answer: Yes, I can.

Although you haven't asked for the solution, here it is anyway:

2^x = e^(x+2)

x ln(2) = x+2

x ln(2) - x = 2

x [ ln(2) - 1 ] = 2

x = 2 / [ ln(2) - 1 ]

x = 2 / -0.3069... = - 6.518... (rounded)

$2^x=e^(x+2)\n \n ln(2^x)=ln(e^(x+2))\n \n xln(2)=(x+2)ln(e)\n \n xln(2)=x+2\n \n (x+2)/(x)=ln(2)\n \n (x)/(x)+(2)/(x)=ln(2)\n \n 1+(2)/(x)=ln(2)\n \n (2)/(x)=ln(2)-1\n \n \boxed{x=(2)/(ln(2)-1)}$
