use the table of values to write the exponential function

Answers

Answer:

[tex]\frac{1}{2}(\frac{1}{4}^x)[/tex]

Step-by-step explanation:

To find the function, compare the y values. Notice that each y value decreases by being divided by 4. This means the base of the exponential is 1/4.

To find the initial value, consider the point (0,0.5). When 1/4 is raised to the 0 power, the value is 1. This leaves that the initial value is 1/2 since 1/2*1 = 0.5.

The function is [tex]\frac{1}{2}(\frac{1}{4}^x)[/tex].

Answer:

The required function is [tex]f(x)=\frac{1}{2}\left(\frac{1}{4}\right)^x[/tex].

Step-by-step explanation:

The general exponential function is

[tex]f(x)=ab^x[/tex]           .... (1)

where, a is the initial value and b is growth factor.

From the given table it is clear that the function passes through the points (0,0.5) and (-1,2). It means the equation of function must be satisfied by the points (0,0.5) and (-1,2).

Substitute f(x)=0.5 and x=0 in equation (1), to find the value of a.

[tex]0.5=ab^0[/tex]

[tex]0.5=a[/tex]

The value of a is 0.5.

Substitute a=0.5, f(x)=2 and x=-1 in equation (1), to find the value of b.

[tex]2=(0.5)b^(-1)[/tex]

[tex]2=\frac{0.5}{b}[/tex]

[tex]2b=0.5[/tex]

Divide both sides by 2.

[tex]b=\frac{0.5}{2}[/tex]

[tex]b=0.25[/tex]

The value of b is 0.25.

Substitute a=0.5 and b=0.25 in equation (1).

[tex]f(x)=0.5(0.25)^x[/tex]

[tex]f(x)=\frac{1}{2}(\frac{1}{4})^x[/tex]

Therefore the required function is [tex]f(x)=\frac{1}{2}\left(\frac{1}{4}\right)^x[/tex].

Answers

(12/7, 9/7)

Since y = -x + 3, substitute it into the first equation.

-x + 3 = 5/2x - 3

Now add x and subtract 3 from both sides.

0 = 7/2x - 6

Now add 6 on both sides.

6 = 7/2x

Now divide by 7/2 on both sides.

12/7 = x

Now, just substitute x into the second equation.

y = -12/7 + 3

y = -12/7 + 21/7

y = 9/7

If F(x)=2^x +5x and g(x)=3x-5 find (f+g)(x)

Answers

Final answer:

The sum of the functions [tex]F(x) = 2^x + 5x[/tex] and g(x) = 3x - 5 is [tex](f+g)(x) = 2^x + 8x - 5[/tex], which is obtained by adding the corresponding elements of each function and combining like terms.

Explanation:

The question asks for the sum of two functions, F(x) and g(x). In mathematical terms, (f+g)(x) means we have to add the functions F(x) and g(x) together. This is done by adding the corresponding elements of each function.

Here are the given functions:

F(x) = 2x + 5x

g(x) = 3x - 5

To find (f+g)(x), we combine them like this:

(f+g)(x) = F(x) + g(x) = (2x + 5x) + (3x - 5)

Now, we simply combine like terms:

(f+g)(x) = 2x + 5x + 3x - 5

(f+g)(x) = 2x + 8x - 5

This is the simplified form of the sum of the functions F(x) and g(x).

Final answer:

To find (f+g)(x) where f(x)=2ˣ + 5x and g(x)=3x-5, you simply add the functions together to get (f+g)(x) = 2ˣ + 8x - 5.

Explanation:

The student has asked to find (f+g)(x) where f(x) = 2ˣ + 5x and g(x) = 3x - 5.

To find (f+g)(x), we add the two functions together:

f(x) = 2ˣ + 5xg(x) = 3x - 5

So, (f+g)(x) is:

(f+g)(x) = (2ˣ + 5x) + (3x - 5)

Combine like terms:

(f+g)(x) = 2ˣ + 5x + 3x - 5

(f+g)(x) = 2ˣ + 8x - 5

That is the simplified form of the function (f+g)(x).

Which expression defines the arithmetic series 2.3 + 2.6 + 2.9 + for five terms

Since this series is an arithmetic series so explicit formula of series will be [tex]\sum_{n=1}^{n}[a+(n-1)d][/tex] where a is the first term, d is the common difference and n is the number of term.

Therefore, we replace the values a = 2.3, and d = (2.6 - 2.3) = (0.3)

Answers

Answer:

Im not sure about the other 2 but the last box is 12, the answer above is incorrect for PLATO. I just took the test.

Final answer:

The y-intercept of line AB is 0, and the equation of line CD is y = 5.

Explanation:

The y-intercept of a line is the point where it intersects the y-axis. In this case, we are given the coordinates of point A as (8, 0). Since the y-coordinate of point A is 0, the y-intercept of line AB is 0.

The equation of a line can be determined using the slope-intercept form, which is y = mx + b, where m represents the slope and b represents the y-intercept. The slope of line CD can be found by finding the difference in y-coordinates divided by the difference in x-coordinates between points C and D. In this case, the slope is (5 - 5) / (5 - 5) = 0. Therefore, the equation of line CD is y = 0x + b, where b is the y-intercept. Since point D has coordinates (5, 5), the y-intercept is 5. Therefore, the equation of line CD is y = 0x + 5, or simply y = 5.

Final answer:

The product of the polynomials 7x - 4 and 8x + 5 is 56x^2 + 3x - 20, attained by applying the FOIL method.

Explanation:

The given question asks to find the

product

of two polynomials: 7x - 4 and 8x + 5. The product of two polynomials can be found using the distributive property, also known as the FOIL (First, Outer, Inner, Last) method. So, start by multiplying the first terms of each polynomial: 7x * 8x = 56x^2. Then, multiply the outer terms: 7x * 5 = 35x. Next, the inner terms: -4 * 8x = -32x. And finally, the last term: -4 * 5 = -20. Summing all these gives the final answer: 56x^2 + 3x - 20.

Evaluate

Final answer:

To calculate the remaining amount of an element undergoing exponential decay, use the formula A = A0 * (1 - r)^t, where A is the remaining amount, A0 is the initial amount, r is the decay rate per minute, and t is the time in minutes. In this case, approximately 12.3 grams of the element is remaining after 14 minutes.

Explanation:

To calculate the amount of the element remaining after 14 minutes, we need to use the formula for exponential decay, which is A = A0 * (1 - r)t, where A is the remaining amount, A0 is the initial amount, r is the decay rate per minute (in decimal form), and t is the time in minutes.

In this case, the initial amount is 570 grams, the decay rate is 26.9% or 0.269 per minute, and the time is 14 minutes.

Plugging these values into the formula, we get:

A = 570 * (1 - 0.269)14 = 570 * (0.731)14 = 570 * 0.0221 = 12.27 grams.

Therefore, approximately 12.3 grams of the element is remaining after 14 minutes.

What is the distance between two points located at (–6, 2) and (–6, 8) on a coordinate plane?"

Answers

Answer:

4 units

Step-by-step explanation:

X coordinate never changed so you just need to subtract 2 from 8 to see the unit difference.

The distance between the two points (-6, 2) and (-6, 8) on a coordinate plane is 6 units, as they share the same x-coordinate, and the distance can be found by the absolute value of the difference in y-coordinates.

The distance between two points on a coordinate plane can be determined by finding the absolute difference between their x-coordinates if they share the same x-coordinates or their y-coordinates if they share the same y-coordinates. Since the points (-6, 2) and (-6, 8) share the same x-coordinate, we can subtract the y-coordinates to find the distance:

Distance = |y2 - y1|
= |8 - 2|
= |6|
= 6 units

Therefore, the distance between the two points located at (-6, 2) and (-6, 8) on a coordinate plane is 6 units.

Which equations correctly represent a line that has a slope of -2/3 and passes through the points (–2, 8) and (1, 6)?

Answers

Answer:

2x + 3y = 20

Step-by-step explanation:

Slope of the line is -2/3 .  We can use any of the given points to find the equation of the line. Lets use (1, 6)

The general point-slope form of a line is:

[tex]y-y_{1} =m(x-x_{1} )[/tex]

Here m is the slope which is -2/3

x1 and y1 are the coordinates of the point. So x1 = 1 and y1 = 6

Using these values, we get:

[tex]y-6=-\frac{2}{3} (x-1)\\\\ 3(y-6)=-2(x-1)\\\\ 3y-18=-2x+2\\\\ 2x+3y=20[/tex]

Answer:

2x + 3y = 20

Step-by-step explanation:

We are given two points: (–2, 8) and (1, 6) and the slope (m) of the line and we are to find the equation of this line.

We know that the standard equation of a line is:

[tex]y=mx+c[/tex]

So we will plug in the given values in the above equation to find the y intercept.

[tex]6=-\frac{2}{3} (1)+c[/tex]

[tex]c=\frac{20}{3}[/tex]

So the equation of this line will be:

[tex]y=-\frac{2}{3} x+\frac{20}{3}[/tex]

Answers

Answer:

18

Step-by-step explanation:

Yur Welcome

The answer to the question [tex]\( \frac{12}{2/3} \) is \( 18 \).[/tex]

To solve the expression [tex]\( \frac{12}{2/3} \)[/tex], need to divide 12 by [tex]\( \frac{2}{3} \).[/tex] Dividing by a fraction is the same as multiplying by its reciprocal. Therefore, we can rewrite the expression as:

[tex]\[ 12 \times \frac{3}{2} \][/tex]

Now, multiply 12 by \( \frac{3}{2} \):

[tex]\[ 12 \times \frac{3}{2} = \frac{12 \times 3}{2} \][/tex]

[tex]\[ \frac{12 \times 3}{2} = \frac{36}{2} \][/tex]

Finally, divide 36 by 2 to get the result:

[tex]\[ \frac{36}{2} = 18 \][/tex]

So, [tex]\( \frac{12}{2/3} = 18 \)[/tex]. This is the value you would use if this calculation appears on your module exam.
