write the expression as a single logarithm with coefficient 1. assume all variables represent positive real numbers. 1/4logbx^5y^7-4/7logbx^4y
the formula as one logarithm with a coefficient of 1 with a expression. assume all variables represent positive real numbers. 1/4logbx^5y^7-4/7logbx^4y is logbx^4y^11/28
Since the coefficients of the expression of two logs are not the same, we need to adjust the exponents in order to combine them into one logarithm. Since the first logarithm has a coefficient of 1/4, we multiply the exponent of the second logarithm by 4/7 to get 4/7*4 which is equal to 4. We then add 4 to the exponent of the first logarithm to get 11. This gives us a combined logarithm of logbx^4y^11/28.

Show that the function f(x) = x + 5x + 1 has exactly one zero in the interval (-1,0). Which theorem can be used to determine whether a function f(x) has any zeros in a given interval?
The function f(x) = x + 5x + 1 has exactly one zero in the interval (-1, 0). To prove this, we can use the Intermediate Value Theorem.
This theorem states that if a function f(x) is continuous on an interval [a, b] and if its values at a and b have opposite signs, then there exists at least one root (zero) of the function in the interval (a, b). Therefore, since f(-1) = -6 and f(0) = 1, both of which have opposite signs, the Intermediate Value Theorem can be used to conclude that there exists at least one root of the function in the interval (-1, 0).
Furthermore, since the function is a quadratic function of the form f(x) = ax2 + bx + c, it is known that a quadratic equation can have at most two roots (zeros) (in a given interval). Therefore, since the Intermediate Value Theorem implies that the function f(x) has at least one zero in the interval (-1, 0), it follows that the function has exactly one zero in the interval (-1, 0).

The interest rate for Rebeka's account is 5%.
What is the meaning of interest rate?
The amount that the lender charges the borrower over and beyond the principal amount is referred to as the interest rate. A person who deposits money in a bank or other financial institution also earns additional income in terms of the recipient, known as interest, taking into account the time value of money.
Given that, Rebeka deposits $1500. She earn $131.25 as interest after 21 months.
The formula of simple interest is
I = PRT
I = interest
P = Principal
R = Rate of interest
T = time
In the given question,
P = $1500
I = $131.25
T = 21 months = 21/12 years.
Putting P = $1500, I = $131.25, T = 21/12 years in I = PRT:
131.25 = 1500 × R × (21/12)
Divide both sides by 1500 × (21/12):
R = 131.25 /[1500 × (21/12)]
R = [131.25 × 12] /[1500 × 21]
R = 0.05
R = 5%

Nathan is going to drive from his house to City A without stopping. Let D represent
Nathan's distance from City At hours after leaving his house. A graph of D is shown
below. Write an equation for D then state the slope of the graph and determine its
interpretation in the context of the problem.
The linear function for D is defined as follows:
D(t) = -35t + 280.
The slope of 35 means that Nathan is traveling at a velocity of 35 miles/km per hour.
How to define the linear function?The linear function for this problem is defined in slope-intercept format, as follows:
y = mx + b.
The coefficients of the function are given as follows:
m is the slope, representing the rate of change of the output variable y relative to the input variable x.b is the y-intercept, representing the initial value of the output variable y.From the table, two points are given as follows:
(3, 175) and (5,105).
Given two points, the slope is calculated as the change in y divided by the change in x, hence:
m = (105 - 175)/(5 - 3) = -35.
This slope represents that Nathan is traveling at a velocity of 35 miles/km per hour.
Hence:
D(t) = -35t + b
When x = 3, y = 175, hence the intercept b is obtained as follows:
175 = -35(3) + b
b = 280.
Thus the function is of:
D(t) = -35t + 280.

The sum of the areas of the enclosed regions is given by
A = ∫[0-A] (g(x) - f(x)) dx + ∫[A - 2] (f(x) - g(x)) dx

Graph the points (0.5,4.5) and (-0.5,-4.5)
Answer:
Step-by-step explanation:
To graph the points (0.5, 4.5) and (-0.5, -4.5) on a coordinate plane, you can use a ruler or a graph paper to plot the points.
To plot the point (0.5, 4.5), start by drawing the horizontal and vertical axes of the coordinate plane. The horizontal axis, or the x-axis, is the line that runs horizontally across the plane, and the vertical axis, or the y-axis, is the line that runs vertically. The intersection of the two axes is called the origin.
Next, locate the point (0.5, 4.5) on the coordinate plane. To do this, find the point that is 0.5 units to the right of the y-axis and 4.5 units above the x-axis. This point is the point (0.5, 4.5).
To plot the point (-0.5, -4.5), locate the point that is 0.5 units to the left of the y-axis and 4.5 units below the x-axis. This point is the point (-0.5, -4.5).
The resulting graph should look like this:

After 3 years, the value of the car will be approximately $20,959.34.
The depreciation of an asset is the reduction in the value of the asset over time due to wear and tear, obsolescence, or other factors. The depreciation equation is used to calculate the amount by which the value of an asset decreases each year.
The value of the car after 3 years can be represented by the following equation:
V = 26600 * (1 - 0.09)^3

The Subtotal for 25 flash drives is $250.00. You can save $62.50. The new Subtotal becomes $187.50. Sales tax of 4% will equal $7.50. The Total for the 25 flash drives will be $187.50 + $7.50 which gives $195.00
To find the solution, we must solve for the questions individually;
The Subtotal is 25 x $10 = $250.00
You save = 25% of $250
which is 25/100 x 250 = $62.50
The new Subtotal = $187.50
Sales tax of 4% = 4% of $187.50
