1.5x - 3y = 6 (solve for y)
An equation is formed of two equal expressions. The value of y for the given equation is (1.5x - 6)/3.
What is an equation?An equation is formed when two equal expressions are equated together with the help of an equal sign '='.
1.5x - 3y = 6
Subtract 1.5x from both the sides of the equation,
1.5x - 3y - 1.5x = 6 - 1.5x
-3y = 6 - 1.5x
Divide both the sides of the equation by -3,
-3y/(-3) = (6 - 1.5x)/(-3)
y = (1.5x - 6)/3
Hence, the value of y for the given equation is (1.5x - 6)/3.

The graph of f(x) = log x + 3 is the graph of
g(x) = log x translated 3 units a)up b)down c)left D) right
Answer:
A)up
Step-by-step explanation:
Given : f(x)=log x +3
g(x)= log x
To Find :
The graph of f(x) = log x + 3 is the graph of g(x) = log x translated 3 units
a)up
b)down
c)left
d) right
Solution:
Rule: f(x)→f(x)+b
So, the graph f(x) is translated up by b units
So, on comparing given f(x) with rule , we can say that the graph g(x) is translated up by 3 units
Thus option A is correct.
Hence The graph of f(x) = log x + 3 is the graph of g(x) = log x translated 3 units up

if f(x)=4-x^2 and g(x)=6x, which expression is equivalent to (g-f)(3)?
To find (g-f)(3), evaluate g(3) and f(3), then subtract f(3) from g(3).
Explanation:To find (g-f)(3), we need to subtract the function f(x) from g(x) and then evaluate the result at x = 3. Let's first simplify the expressions for f(x) and g(x):
f(x) = 4 - x^2
g(x) = 6x
Now substitute these into (g-f)(3) and simplify:
(g-f)(3) = g(3) - f(3)
= 6(3) - (4 - 3^2)
= 18 - (4 - 9)
= 18 - (-5)
= 23
Therefore, (g-f)(3) is equivalent to 23.

If decking cost $5.75 per square feet, how much would it cost to build a deck that is 22 feet by 18.5 feet
It would cost $2338.75 to build a deck that is 22 feet by 18.5 feet at a rate of $5.75 per square foot.
To calculate the cost of building a deck, we need to find the total area of the deck and then multiply it by the cost per square foot.
The area of a rectangle (deck) is given by the formula:
Area = length * width
Given that the deck has a length of 22 feet and a width of 18.5 feet, we can calculate the total area:
Area = 22 feet * 18.5 feet
Area = 407 square feet
Now, to find the total cost of building the deck, we multiply the area by the cost per square foot:
Total cost = Area * Cost per square foot
Total cost = 407 square feet * $5.75/square foot
Total cost = $2338.75
So, it would cost $2338.75 to build a deck that is 22 feet by 18.5 feet at a rate of $5.75 per square foot.

The number n(t) of people in a community who are exposed to a particular advertisement is governed by the logistic equation. initially, n(0) = 500, and it is observed that n(1) = 1000. solve for n(t) if it is predicted that the limiting number of people in the community who will see the advertisement is 50,000. (round all coefficients to four decimal places.)
Rounding the coefficients to four decimal places:
[tex]\[ n(t) = 50000 \times \left(1 - e^{-20.2020t + 0.0101}\right) \][/tex]
The logistic equation governing the number of people exposed to the advertisement in the community is given by:
[tex]\[ \frac{{dn}}{{dt}} = kn \left(1 - \frac{n}{M}\right) \][/tex]
Where:
n(t) is the number of people exposed to the advertisement at time t
k is the growth rate constant
M is the limiting number of people who will see the advertisement
Given:
[tex]\( n(0) = 500 \)[/tex]
[tex]\( n(1) = 1000 \)[/tex]
[tex]\( M = 50000 \)[/tex]
We first need to find the growth rate constant \( k \):
[tex]\[ 1000 = 500 \times \left(1 - \frac{500}{50000}\right) \times k \][/tex]
[tex]\[ 1000 = 500 \times \left(1 - \frac{1}{100}\right) \times k \][/tex]
[tex]\[ 1000 = 500 \times \frac{99}{100} \times k \][/tex]
[tex]\[ k = \frac{1000 \times 100}{500 \times 99} \][/tex]
[tex]\[ k = \frac{2000}{99} \][/tex]
Now, we integrate to find [tex]\( n(t) \)[/tex]:
[tex]\[ \int \frac{{dn}}{{n(1 - \frac{n}{50000})}} = \int \frac{{2000}}{{99}} dt \][/tex]
[tex]\[ -\ln|1 - \frac{n}{50000}| = \frac{{2000}}{{99}}t + C \][/tex]
Using the initial condition [tex]\( n(0) = 500 \)[/tex], we find[tex]\( C \)[/tex]:
[tex]\[ -\ln|1 - \frac{500}{50000}| = 0 + C \][/tex]
[tex]\[ -\ln\left(\frac{99}{100}\right) = C \][/tex]
So, the equation becomes:
[tex]\[ -\ln|1 - \frac{n}{50000}| = \frac{{2000}}{{99}}t - \ln\left(\frac{99}{100}\right) \][/tex]
Solving for n(t) :
[tex]\[ |1 - \frac{n}{50000}| = e^{-\frac{{2000}}{{99}}t + \ln\left(\frac{99}{100}\right)} \][/tex]
[tex]\[ 1 - \frac{n}{50000} = e^{-\frac{{2000}}{{99}}t + \ln\left(\frac{99}{100}\right)} \][/tex]
[tex]\[ \frac{n}{50000} = 1 - e^{-\frac{{2000}}{{99}}t + \ln\left(\frac{99}{100}\right)} \][/tex]
[tex]\[ n(t) = 50000 \times \left(1 - e^{-\frac{{2000}}{{99}}t + \ln\left(\frac{99}{100}\right)}\right) \][/tex]
This is the solution for [tex]\( n(t) \)[/tex]. Now, rounding the coefficients to four decimal places:
[tex]\[ n(t) = 50000 \times \left(1 - e^{-20.2020t + 0.0101}\right) \][/tex]
The figure illustrates the apparatus for a tightrope walker. Two poles are set y = 50 feet apart, but the point of attachment P for the rope is yet to be determined. (a) Express the length L of the rope as a function of the distance x from P to the ground.
Equation for the length L of the rope as a function of the distance x from P to the ground is,
⇒ L = √((x-2)²+50²)
Since L is to the second pole, not x, we can't simply say that;
⇒ x² + y²= L² using the Pythagorean Theorem.
Since, due to that we simply increase the original height by 2, decreasing x by 2.
We can, however, say that ;
⇒ (x-2)² + y² = L²
Plugging 50 as y in, we get ;
⇒ (x-2)² + 50² = L².
Square rooting both sides, we get;
⇒ L = √((x-2)²+50²)
Thus, Equation for the length L of the rope as a function of the distance x from P to the ground is,
⇒ L = √((x-2)²+50²)

How would you write the name of a segment differently than the name of a line
Segments and lines can be named using the letters that represent the points on them, such as AB or line AB.
Explanation:In geometry, segments and lines are fundamental elements. A line is an infinite set of points extending in opposite directions, while a segment is a finite portion of a line with two distinct endpoints. These concepts are essential for understanding geometric shapes, angles, and spatial relationships in mathematics.
In mathematics, the name of a segment and the name of a line can be written differently by using the letters that represent the points on the segment or the line. For example, a segment between points A and B can be written as AB, while a line passing through points A and B can be written as line AB or simply AB. It is important to note that in both cases, the order of the points does not matter, as AB is the same as BA.

om class we learned that in 2010 the federal debt (in millions) was $13,561,623 and the population of the U.S. was 309 million. Use this information to compute the federal debt per capita in 2010.
Answer:
$43888.75
Step-by-step explanation:
We have been given that in 2010 the federal debt (in millions) was $13,561,623 and the population of the U.S. was 309 million.
[tex]\text{The federal debt per capita}=\frac{\text{Total debt}}{\text{Total population}}[/tex]
[tex]\text{The federal debt per capita}=\frac{\$13,561,623}{309}[/tex]
[tex]\text{The federal debt per capita}=\$43888.74757[/tex]
[tex]\text{The federal debt per capita}\approx \$43888.75[/tex]

what is the answer to 72-(-58)-62
The answer to [tex]72 - (-58) - 62[/tex] is 68.
Understanding Double Negatives: When we subtract a negative number, it is equivalent to adding that number. Therefore, [tex]-(-58)[/tex] becomes [tex]+58[/tex].
So, the expression can be rewritten as:
[tex]72 + 58 - 62[/tex]
Performing the Addition: Now we add [tex]72[/tex] and [tex]58[/tex]:
[tex]72 + 58 = 130[/tex]
Performing the Final Subtraction: Next, we subtract [tex]62[/tex] from [tex]130[/tex]:
[tex]130 - 62 = 68[/tex]
Therefore, the final answer is [tex]68[/tex].
