Answer:

The water bottle holds 9 cups of water.

Step-by-step explanation:

1 bottle = 72 oz (ounces)        1 cup = 8 oz (ounces)      1 bottle = ? cups

72 ÷ 8 = 9

9 cups = 72 oz (fluid ounces)

1 bottle = 9 cups

The water bottle holds 9 cups of water.

Here, we have,

given that,

A water bottle holds 72 ounces of water.

so, we get,

1 bottle = 72 oz (ounces)

now, we know that,      

1 cup = 8 oz (ounces)      

so, we have to find that,

1 bottle = ? cups

we have,

if 8 oz = 1 cup

then, 72 oz = 72/8 cups

i.e. we get,

72 ÷ 8 = 9

9 cups = 72 oz (fluid ounces)

1 bottle = 9 cups.

Answer:

y = 2x + 4/5

Step-by-step explanation:

Slope-intercept form is written as:

y = mx + b, where (x,y) is a point on the line, m is the slope, and b is the y-intercept.

To get 10x - 5y = -4 into the form y = mx + b, you'll first want to get y by itself. You can start by subtracting 10x from both sides.

10x - 5y = -4

-5y = -10x - 4

As you can see, y still has a coefficient of -5 in front of it, so we'll have to divide the entire equation by -5 (you have to divide each term individually).

-5y = -10x - 4

y = 2x + 4/5

Answer:

Step-by-step explanation:

The exponential functions have the values of x as;

19) 0.53

20)  5.6

We know that when we are told that a function is an exponential decay function, what it means is that the function is decreasing with time. Thus we are going to put a negative sign and the point of the exponential.

Now we have;

19)

Initial value = 100

Decay rate = 0.95

f(x) = 60

Thus;

60 =100e^-0.95x

60/100 = e^-0.95x

0.6 = e^-0.95x

ln(0.6) = -0.95x

x = ln(0.6) /-0.95

x = 0.53

For 20;

Initial factor = 5000

Decay factor = 0.7

f(x) = 100

Thus;

100 = 5000e^-0.7x

100/5000 = e^-0.7x

0.02 = e^-0.7x

ln(0.02) = -0.7x

x = ln(0.02) / -0.7

x= 5.6

Answer: here

Step-by-step explanation:

8 (1.25) x = 15 8(1.25)^x=15 8 (1.25) x = 15. There are two ways: by using a graph or by using a table. Here, I will use a graph since using a table was already discussed

Using a graphing calculator the value of x is sought by tracing from point 15 up to the curve, at the point of intersection with the curve then trace to the corresponding y direction. At 15 the f(x) is about 227

A curve that depicts an exponential function is known as an exponential graph.

The curve have a horizontal asymptote and either an increasing slope or a decreasing slope. this is to say that the curve begins as a horizontal line, increases or drops gradually, and then the growth or decay accelerates. It may or may not cut the x-axis, but it always cuts the y-axis at some point.

An exponential graph will almost always have a y-intercept but not necessarily an x-intercept.

The corresponding value of each point is located by tracing it using imaginary line

From the x axis at 15  draw an imaginary line up to the curve. the point of intersection of the line and the curve is traced to the y axis. The value at that point gives the required the solution

The graph is attached

Answer:

A = -5/3

B = 52

C = 13

D = -2

Step-by-step explanation:

I recommend using Photomath. It both solves such math problems and also provides explanations!

Answer:

A = -5/3

B = 52

C = 13

D = -2

Let's consider an exponential decay function.

As an example, let's look at [tex]f(\text{x}) = 100(0.5)^{\text{x}}[/tex]

Here is a table of selected values:

[tex]\begin{array}{|c|c|} \cline{1-2}\text{x} & \text{f(x)}\\\cline{1-2}0 & 100\\\cline{1-2}1 & 50\\\cline{1-2}2 & 25\\\cline{1-2}3 & 12.5\\\cline{1-2}4 & 6.25\\\cline{1-2}5 & 3.125\\\cline{1-2}6 & 1.5625\\\cline{1-2}\end{array}[/tex]

As x gets bigger, y = f(x) is slowly approaching y = 0. It will never get to this exact value because we keep taking half of the previous y value (eg: we go from y = 25 to y = 12.5); there's no way to arrive at zero through this continuous halving process. If x/2 = 0, then x itself must be 0. But we started off with a nonzero value.

Visually, the curve is slowly approaching the x-axis. We say that the horizontal asymptote is y = 0 which is directly overlapping the x-axis. Think of the asymptote as an electric fence you can get closer to but not actually touch.

See the graph below. I used Desmos to create the graph.
