D) y=(2)^x-1

Answers

Answer:

The correct option is B) $y=3((1)/(3))^(x)$

Step-by-step explanation:

Consider the provided graph:

The general formula for equation of exponential decay is: $y=ab^(x)$ where $b<1$

The graph of exponential decay $y=ab^(x)$ where $b<1$ as shown in figure 1:

From the figure 1, it is clear that a represents the y intercept and the coordinates are (0,a).

Now, consider the provided Graph:

The y intercept is (0,3)

Therefore, the value of a must be 3.

Now, consider the provided options, only option B) has the value of a = 3.

Therefore, the correct option is: B) $y=3((1)/(3))^(x)$ .

Answer:

B) y=3(1/3)^x

Step-by-step explanation:

Based on the graph, y intercept = 3

So you can plug in x =0 in each functions given in the options to see which one has y-intercept = 3

y= 3 (1/3)^x ; when x = 0, y = 3 * 3^0 = 3 * 1 = 3

So I have no idea how this even works so yeah can somebody please help me

I'll do the first one to get you started.

We want to compare the two fractions 3/4 and 7/8. For now, let's assume they are equal. Chances are they aren't, but we'll assume they are until we know otherwise.

So we have this equation 3/4 = 7/8

Let's cross multiply to get 3*8 = 4*7. Check out the attached image to see what I mean about "cross multiply" if you're not sure.

The equation 3*8 = 4*7 turns into 24 = 28 after you simplify each side. Clearly both sides aren't the same so the equation is not true. Meaning that the original equation 3/4 = 7/8 is not true. The right side of 24 = 28 is larger, so the right side of 3/4 = 7/8 is larger

---------

Here's how it looks like listed out

3/4 = 7/8

3*8 = 4*7

24 = 28

The right side is larger, so we must change all the equal signs to less than signs

3/4 < 7/8

3*8 < 4*7

24 < 28

---------

So that is why 3/4 is less than 7/8

Alternatively, you can use your calculator to find that 3/4 = 0.75 and 7/8 = 0.875; comparing 0.75 and 0.875, we see that 0.875 is larger. Therefore 7/8 is larger.

----------

Final Answer: A less than sign

I need to know if this can make a triangle

Answers

That can't make a triangle. First of all, to make a triangle the length of 2 side add together should be greater than the bigger number of the triangle. So, 45+8=53. The bigger triangle is 90.
