The exponential function for the data in the table is given as follows:

[tex]y = 0.0625(2)^x[/tex]

An exponential function has the definition presented as follows:

[tex]y = ab^x[/tex]

In which the parameters are given as follows:

When the input x increases by one, the output y is doubled, hence the parameter b has the value given as follows:

b = 2.

The parameter a is the value of y when x = 0. When x = 1, the output is double when x = 0, as b = 2, hence:

2a = 0.125

a = 0.0625.

Thus the function is:

[tex]y = 0.0625(2)^x[/tex]

Step-by-step explanation: READ THIS IS IF YOU ARE HAVING TROUBLE LIKE I DID!! Anytime you are trying to find the circumference of a circle, you multiply the radius (the 20 ft part) by 3.14, 3.14 is a number known as Pi. Number five should be 314.16, you take the radius and put it to the power of Pi. Use this formula for the area: 3.14 X half of the length of the circle (radius) then put it to the power of 2.

The figure shows a graph of the function fx in the coordinate plane. f2 is greater than g2.

As the graph of function f(x) is a parabola, so that the equation of function f(x) is:

f(x) = [tex]ax^2+bx+c[/tex]

As it can be seen in thee figure, the graph of function f(x) cross points (0;8) ;(-2; 0) and (4;0)

=> f(0) = 8; f(-2) = 0; f(4) = 0

We have:

f(x=0) = a x 0 + b x 0 + c = 8  => c = 8

We have:

+) 4a -2b + 8 = 0 => 2 x (4a -2b + 8) = 8a - 4b + 16 = 0 (1)

+) 16a + 4b + 8 = 0 (2)

We take (2) minus (1)

=> (16a + 4b + 8) - (8a - 4b + 16) = 0

=> 8a - 8 = 0 => a = 1

Replace a = 1 into (1)

=> 8 x 1 - 4b + 16 = 0 => b = 6

f (2) = 2^2 + 6 x 2 + 8 = 24

g (2) = 3 -2 + 2 = 3

Thus, f(2) is greater than g(2).

Answer:

$839.20

Step-by-step explanation:

To find the finance charge, we need to first calculate the total amount financed, which is the price of the snow thrower minus the down payment.

The down payment is 20% of $1,501, which is:

0.20 x $1,501 = $300.20

So the total amount financed is:

$1,501 - $300.20 = $1,200.80

The total amount of the 12 monthly payments is:

12 x $170 = $2,040

The finance charge is the difference between the total amount of the payments and the amount financed:

$2,040 - $1,200.80 = $839.20

Therefore, the finance charge is $839.20.

Step-by-step explanation:

Starting with the equation E = mgh, we can solve for h in terms of E, m, and g as follows:

E = mgh

Divide both sides by mg:

E/mg = h

Therefore, h = E/mg.

So the solution for h in terms of E, m, and g is h = E/mg.

The reduced row echelon form of the matrix is given as follows:

The row echelon form of a matrix contains the entire matrix except the last column in the format of an identity matrix, with the last column containing the solution to the system of equations represented by the matrix.

The matrix in the context of this problem is defined as follows:

[tex]\left[\begin{array}{cccc}-1&5&-3&6\\0&3&6&-42\\0&-6&-1&18\end{array}\right][/tex]

First we want a value of 1 at line 1, column 1, hence we multiply the first line by -1, that is:

R1 -> -R1.

Hence:

[tex]\left[\begin{array}{cccc}1&-5&3&-6\\0&3&6&-42\\0&-6&-1&18\end{array}\right][/tex]

Then we want a value of 1 at line 2 column 2, thus:

R2 -> R2/3.

Hence:

[tex]\left[\begin{array}{cccc}1&-5&3&-6\\0&1&2&-14\\0&-6&-1&18\end{array}\right][/tex]

Then we want a value of 0 at line 3, column 2, hence:

L3 -> L3 + 6L2

[tex]\left[\begin{array}{cccc}1&-5&3&-6\\0&1&2&-14\\0&0&11&-66\end{array}\right][/tex]

Then the solution to the system of equations is given as follows:

The solution to the inequality |x − 2| ≥ 5 is x ≤ -3 or x ≥ 7.

We have,

To solve the inequality |x − 2| ≥ 5, we need to consider two cases:

Case 1:

x - 2 is non-negative (i.e., x - 2 ≥ 0)

In this case, the absolute value simplifies to x - 2, so we have:

x - 2 ≥ 5

Adding 2 to both sides, we get:

x ≥ 7

So any value of x that is greater than or equal to 7 satisfies the inequality.

Case 2:

x - 2 is negative (i.e., x - 2 < 0)

In this case, the absolute value simplifies to -(x - 2), so we have:

-(x - 2) ≥ 5

Multiplying both sides by -1, we get:

x - 2 ≤ -5

Adding 2 to both sides, we get:

x ≤ -3

So any value of x that is less than or equal to -3 satisfies the inequality.

Therefore,

The solution to the inequality |x − 2| ≥ 5 is x ≤ -3 or x ≥ 7.

The Absolute value function takes the same value for positive and negative values of its argument.

The graph of the absolute value function y = -|x + 6|, we first need to understand the properties of an absolute value function.

The absolute value of a number is its distance from 0 on the number line. Thus, the absolute value function |x| will always return a non-negative value, regardless of the sign of x. When the absolute value function is multiplied by -1, as in -|x|, the function reflects the graph over the x-axis and makes it negative.

Applying these principles to the given function y = -|x + 6|, we can start by identifying the vertex, which is the point where the absolute value term inside the function equals 0. In this case, the vertex is at x = -6.

Next, we can plot some points to get a sense of the shape of the graph. We can choose values of x that are greater than or less than -6, and use the fact that the function is negative to find the corresponding y-values. For example:

- When x = -7, y = -|(-7) + 6| = -1

- When x = -5, y = -|(-5) + 6| = -1

We can see that the graph has a "V" shape, with the vertex at (-6,0). The line of symmetry is the vertical line passing through the vertex, which is the equation x = -6. The graph approaches the x-axis on either side of the vertex, but never touches it. The negative sign in front of the absolute value term causes the graph to be reflected over the x-axis.

since the absolute value function takes the same value for positive and negative values of its argument.

The net force on the knot is 42.7 N. Therefore, option D is the correct answer.

The force of 301 N to the North can be broken into components of 301 N in the x-direction and 0 N in the y-direction.

The force of 280 N at 10.0° South of East can be broken into components of 250.5 N in the x-direction and -247.8 N in the y-direction.

The force of 313 N to the Southwest can be broken into components of -208.1 N in the x-direction and -278.9 N in the y-direction.

The net force is then the sum of the components in both the x- and y-directions.

The net force in the x-direction is 301 N + 250.5 N - 208.1 N = 343.4 N and the net force in the y-direction is 0 N - 247.8 N - 278.9 N = -526.7 N.

The net force is then the hypotenuse of a right triangle with the x- and y-components as the legs.

The net force is thus equal to √(343.4 N² + (-526.7 N)²) = 42.7 N.

Therefore, option D is the correct answer.

The Chillan earthquake had an intensity about 5 times greater than the Taiwan earthquake.

The Richter scale is logarithmic, meaning that a difference of 1 on the scale corresponds to a tenfold difference in the amplitude of the seismic waves. Therefore, we can calculate the difference in intensity between the two earthquakes using the formula:

difference in intensity

= 1[tex]0^{((magnitude of earthquake 1) - (magnitude of earthquake 2))[/tex]

For the Chillan earthquake:

magnitude = 8.3

difference in magnitude = 8.3 - 7.6 = 0.7

For the Taiwan earthquake:

magnitude = 7.6

Plugging these values into the formula, we get:

difference in intensity = 10^(0.7) = 5.01187

Find the sum of the first six terms of the geometric sequence for which a2 = 0.7 and a3 = 0.49.

Let the common ratio of the geometric sequence be r. Then we have:

a2 = ar = 0.7

a3 = ar^2 = 0.49

Dividing the second equation by the first, we get:

r = a3/a2 = 0.49/0.7 = 7/10

So the first six terms of the sequence are:

a1 = a2/r = 0.7/(7/10) = 1

a2 = 0.7

a3 = 0.49

a4 = ar^2 = 0.343

a5 = ar^3 = 0.2401

a6 = ar^4 = 0.16807

The sum of the first six terms is:

S6 = a1 + a2 + a3 + a4 + a5 + a6

S6 = 1 + 0.7 + 0.49 + 0.343 + 0.2401 + 0.16807

S6 = 2.94017

Therefore, the sum of the first six terms of the geometric sequence is approximately 2.94017.
