Data

• Increase: 6% per month

• Current users: 21,740

• Users after 8 months: ?

Procedure

As we are increasing 6%, we have to multiply the original quantity, which represents the 100%, times 100% plus the increase (6%). However, this must be done in decimals:

Then, for the first month the user base will be:

Then, for the second month the user base will be:

The third month would be:

We could do this for eight months or we can take a shortcut:

where U represents the user, U0 is the initial users, i is the increase rate, and n is the number of months.

Replacing the data we have we get:

Answer: 34,650.26 users after 8 months with a 6% increase per month.

The solution set for y = 4x-3 is {(2,5)} from the replacement set {(-3, 9), (-2, -11), (0, -2), (2,5)}.

The provided function is an equation of line in slope-intercept form of line.

According to which, if a line has slope m and it has the Y-intercept c, then the equation of line will be,

y = mx+c,

One thing to be noted here is, if the line passes through (a,b) then it will satisfy the equation and also, it will be called a solution of the equation.

The equation is y = 4x-3,

The given replacement sets is, {(-3, 9), (-2, -11), (0, -2), (2,5)}.

We will check for each and every element of the set,

1. For (-3,9)

Putting values in,

y = 4x-3

9 = 4(-3)-3

9 ≠ -15

Not a solution.

2. For (-2,11)

Putting values in,

y = 4x-3

11 = 4(-2)-3

11 ≠ -11

Not a solution.

3. For (0,-2)

Putting values in,

y = 4x-3

-2 = 4(0)-3

-2 ≠ -3

Not a solution.

4. For (2,5)

Putting values in,

y = 4x-3

5 = 4(2)-3

5 = 5

It is a solution for the equation y = 4x -3.

We have the explicit equatiion:

The 8th term is 78

y = 10 * 8 - 2

y = 80 - 2

We replaced x by 8

Therefore, for finding the 9th term, we calculate the value this way:

y = 10 * 9 - 2

y = 90 - 2

y = 88

The 9th term of the series is 88

Shavon is running faster by 0.33 meter.

From the information, Shavon and Jesiah are having a race and Shavon can run 100 meters in 30 seconds. The speed will be:

= Distance / Time

= 100 / 30

= 3.33 meter per second

Jesiah can run 120 meters in 40 seconds. The speed will be:

= Distance / Time

= 120 / 40

= 3 meters per second.

Shavon runs faster. This is illustrated as:

The two ways to find solution of the expression (17-8) are by direct arithmetic method and indirect simplification method.

In arithmetic method, the first step is to determine whether the numbers are rational or irrational, so as to simplify the solution process. If numbers are rational, then they are checked for the sign determining their position on number line and then the calculations are performed. Here, 17 is positive rational number and -8 is negative rational number. Hence, 17-8 is equalized to 9. In indirect simplification method, the numbers to be subtracted are broken down to simpler terms which can be easily subtracted and reduced to get the answer. In the subtraction of 17-8, we break 8 in the form of (7+1). Then the expression becomes 17 - (7+1). Now, this expression can easily be solved to get the answer. Therefore, 17 - (7+1) = 10 - 1 = 9.

Answer:

The correct option is 3.

Step-by-step explanation:

The parent cube root function is

From the given graph it is clear that the graph of f(x) is transformed by reflecting the graph of g(x) across y-axis and shifting two units down.

If the parent cube root function is reflected across the y-axis, then x is replaced by -x.

Now, the graph of new function sifts 1 unit down. So, the required function is

The graph shows the function .

From the given graph it is clear that the graph passes through the points (-8,1), (0,-1) and (8,-3).

Check the above function by these points.

At x=-8,

At x=0,

At x=8,

All these points satisfy by the abobe function. It means the above function is correct.

A geometric sequence is one in which the ratio of two succeeding terms is fixed. The common ratio is what's known as this ratio.

Checking each sequence one by one right now.

(i) –2.7, –9, –30, –100, ...

The factors of the expression are 2.5 and 11/5.

In mathematics, an expression that incorporates variables, constants, and algebraic operations is known as an algebraic expression (addition, subtraction, etc.). Terms comprise expressions. Similar to this, we are describing an algebraic expression when we explain an expression in words that has a variable (an expression with a variable). For instance, the algebraic expression for "3 more than x" can be written. x + 3.
