If f(x) is an exponential function where f(4) = 7 and f(5.5) = 53, then find thevalue of f(5), to the nearest hundredth.

Given:

f(x) is an exponential function.

f(4) = 7.

f(5.5) = 53.

Since f(x) is an exponential function, f(x) can be expressed as,

[tex]f(x)=ab^x[/tex]Here, a and b are constants.

Hence, we can write

[tex]\begin{gathered} f(4)=ab^4----(1) \\ f(5.5)=ab^{5.5}\text{ ------(2)} \end{gathered}[/tex]Divide equation (2) by (1).

[tex]\frac{f(5.5)}{f(4)}=\frac{ab^{5.5}}{ab^4}[/tex]Substitute f(4) = 7 and f(5.5) = 53 in the above equation.

[tex]\begin{gathered} \frac{53}{7}=\frac{b^{5.5}^{}}{b^4} \\ \frac{53}{7}=b^{5.5-4} \\ \frac{53}{7}=b^{1.5} \\ \frac{53}{7}=b^{\frac{3}{2}} \\ b=(\frac{53}{7})^{\frac{2}{3}} \\ b=3.855 \end{gathered}[/tex]Now, the value of a can be obtained as,

[tex]\begin{gathered} f(4)=ab^4 \\ 7=a(\frac{53}{7})^{\frac{2}{3}} \\ a=\frac{7}{(\frac{53}{7})^{\frac{2}{3}}} \\ =1.815 \end{gathered}[/tex]To draw a graph for y = 3/4x + 7, a person can draw a point at x of 0 and y of ___, a second point by going up 3 and over ___, and then draw a line through the points.

To **draw** a graph for y = 3/4x + 7, a person can draw a point at x of 0 and y of y = 7, a second point by going up 3 and over y = 10, and then draw a line through the **points**.

How to know if a point lies in the **graph** of a **function**?

All the points (and only those points) which lie on the **graph** of the function satisfy its **equation**. Thus, if a point lies on the graph of a **function**, then it must also satisfy the function.

Given that:

y = 3/4x + 7

At x = 0

y = 7.

Going over by 3 then,

7 + 3 = 10.

So, now y = 10

10 = 3/4x +7

3/4x = 10-7

3/4x = 3

x = 4.

Now,

To draw a **graph** of 3/4x + 7, a person can draw c point x of 0 and y of 7, a second point by going over 3 and up 4.

Thus, for drawing the graph for y = 3/4x + 7, a person can draw a point at x of 0 and y of 7, a second **point** by going over 3 and up 10 and then draw a line through the points.

As the banana is 7 inches long and each piece is 1/2 inches you divide 7 into 1/2 to find how many slices of banana can be cut:

To classify the equations, we will need to define some terms:

Inconsistent equations: Inconsistent equations is defined as two or more equations that are impossible to solve based on using one set of values for the variables.

inconsistent equations of linear equations are equations that have no solutions in common.

An example of a set of inconsistent equations is x+2=4 and x+2=6.

Independent equation: The equations 3x + 2y = 6 and 3x + 2y = 12 are independent because any constant times one of them fails to produce the other one.

Dependent system: Equations in a dependent system can be derived from one another; they describe the same line

We can now proceed to classify the equations.

Solving the **inequality** the range of x becomes 9.523 ≤ x ≤ 22.222.

The given inequality which needs to be solved is 200 ≤ 15.75x + 50 ≤ 400.

If 50** **is **subtracted **from each part or side of the inequality we get,

200 - 50 ≤ 15.75x + 50 - 50 ≤ 400 -50 which will be equal to,

150 ≤ 15.75x ≤ 350, now to solve this inequality **divide** the given inequality with the **coefficient **of x which is 15.75 to get the range of x.

Hence the inequality becomes 150÷15.75 ≤ 15.75x÷15.75 ≤ 350÷15.75. solving this equation the value of x becomes 9.523 ≤ x ≤ 22.222.

What is the value of x?

**Answer: x = 50**

**Step-by-step explanation:**

The two angles are opposite each other, meaning that they are equivalent.

So, we can set them equal to each other and then solve for x.

2(x + 10) = 3x - 30

2x + 20 = 3x -30

x = 50

**Answer:**

x = 50

**Step-by-step explanation:**

Since the two angles are opposite each other, you know that they are equal.

Set both equations equal to each other to isolate x:

2(x + 10) = 3x - 30

Distribute 2 on the left side

2x + 20 = 3x - 30

Subtract 2x from both sides

20 = x - 30

Add 30 to both sides

Monthly gross= $3,690.

12 months in a year, multiply $3,690 x 12= $44,280 grossed in a year.

Housing recommendation is 30% of yearly gross income.

Multiply 30% x $44,280 = $13,284. Then divide by 12, $13,284 divided by 12= $1,107.

12 months in a year, multiply $3,690 x 12= $44,280 grossed in a year.

Housing recommendation is 30% of yearly gross income.

A court order restricted the number of marchers to 300 when passing over a stretch of two-lane highway. However, on the final day of the march, when the road reached four lanes the number of demonstrators swelled to 25,000.

What was the percentage of increase?

The **percentage increase **is 88%.

The **difference **between the **final **value and the **starting **value, stated as a **percentage**, is known as a **percentage increase**. The **initial **value and the enhanced (**new**) value are **required **in order to **calculate **the **percentage**.

**Finally**, number of marchers = 25000

**Change **in **amount **= 25000- 300 = 22000

Now, the **percent increase**
