Answer:
(C) Square feet
Step-by-step explanation:
In order to take the measurements, he should use the square feet unit of measure.
As, the cubic feet also known as unit of volume can be defined as the volume of the cube with sides of one foot in length. Since, the bathroom is two dimensional therefore, cubic feet can't be used.
Yards are basically a unit of length use to measure length and perimeter and square yards are used in measuring the long space and the bathroom is bit too small for it.
Therefore, square feet should be used to measure.

Create a log expression, using the laws of logs, that simplifies to 7^x = 64.
This makes no sense to me! Help!
What are the log laws?
To create a log expression that simplifies to 7^x = 64, we need to use the logarithmic and exponential laws.
Explanation:To create a log expression that simplifies to 7^x = 64, we need to use the logarithmic and exponential laws.
First, we can rewrite the exponential equation as a logarithmic equation, which is x = log7(64).Next, we can use the logarithmic property that states logb(ax) = x * logb(a). Applying this property, we have x = log7(26) = 6 * log7(2).Therefore, the log expression that simplifies to 7^x = 64 is x = 6 * log7(2).

A plumber charges a $45 fee to make a house call and then $25 for each hour of labor. The plumber uses an equation in the form y=mx +b to determine the amount to charge each customer. What is the value of m in the equation?
Answer:
Let x represents the number of hours of labor and y represents the total charges.
Since, in the given situation,
The total charges = A fixed charge for house call + Extra charge per hours,
Fixed charge for house call = $ 45,
Extra charges for every hour = $ 25,
⇒ Extra charge for x hours = 25 x,
Thus, the total charges for x hours,
y = 45 + 25 x
Which is the required equation that will use to determine the amount to charge each customer.
By comparing this equation with y = mx + c,
m = 25
Which of the following is the inverse function of y = 3x + 1?
x = 3y + 1
y = (1/3)x + 1/3
y = (x – 1)/3
y = x/3 - 1
Answer:
Option C is the correct answer : [tex]y=\frac{(x-1)}{3}[/tex]
Step-by-step explanation:
[tex]y=3x+1[/tex]
For finding the inverse of this function, we will interchange x and y, then solve for y.
[tex]3y=x-1[/tex]
[tex]y=\frac{x-1}{3}[/tex]
Hence, option C is the correct answer : [tex]y=\frac{(x-1)}{3}[/tex]

The following set of coordinates represents which figure?
(3, -5), (5, -2), (10, -4), (8, -7)
A. parallelogram
B. rectangle
C. trapezoid
D. square
...?
Answer:
Option A is correct.
Step-by-step explanation:
Given:
Coordinates of the figure are ( 3 , -5 ) , ( 5 , -2 ) , ( 10 , 4 ) and ( 8 , -7 )
To find: Shape of the figure.
First we plot the given coordinates of the point on the graph then see which shape we obtained.
Graphing these points we get attached graph.
Clearly from graph it is a parallelogram because opposite sides are equal and parallel.
It is not a rectangle as clearly from graph angles at vertex are not right angle.
Therefore, Option A is correct.
To identify the geometric figure that the coordinates represent, plot the points, determine the slopes and lengths of the sides, and verify the properties of the geometric figures such as parallel sides and right angles.
Explanation:The student has provided the coordinates of a figure and asks which geometric figure they represent. To determine the figure, we need to consider the characteristics of the points given.
The coordinates provided are (3, -5), (5, -2), (10, -4), and (8, -7). By plotting these points on a Cartesian plane and connecting them in order, we could identify the figure based on the slopes of the sides and the lengths of the segments, which indicate parallel and perpendicular lines.
We need to calculate the distances between consecutive points and the slopes of the lines to confirm whether opposite sides are equal and parallel (a characteristic of a parallelogram) and whether all angles are right angles (a characteristic of a rectangle). These calculations can confirm the identity of the figure.

Solve the inequality 2x - 3 < x 2 ≤ 3x 5. show your work
Answer:
-3/2 ≤ x < 5
Step-by-step explanation:
2x - 3 < x + 2 ≤ 3x+5
Solve the inequality separately
2x-3 <x+2 and x+2≤ 3x+5
LEts solve one by one
2x-3 <x+2
Subtract x from both sides
x -3 < 2
add 3 on both sides
x< 5
x+2≤ 3x+5
Subtract 3x from both sides
-2x + 2 ≤ 5
Subtract 2 from both sides
-2x ≤ 3
Divide both sides by -2
x ≥ -3/2
we got x>= -3/2 and x<5
so x lies between -3/2 and 5
-3/2 ≤ x < 5
The solution to the given inequality is -3/2 ≤ x < 5.
To solve the given inequality: 2x - 3 < x + 2 ≤ 3x + 5, we can break it down into two separate inequalities and solve them individually.
2x - 3 < x + 2:
Subtracting x from both sides:
2x - x - 3 < x - x + 2
x - 3 < 2
Adding 3 to both sides:
x - 3 + 3 < 2 + 3
x < 5
Now x + 2 ≤ 3x + 5:
Subtracting x from both sides:
x - x + 2 ≤ 3x - x + 5
2 ≤ 2x + 5
Subtracting 5 from both sides:
2 - 5 ≤ 2x + 5 - 5
-3 ≤ 2x
Dividing both sides by 2:
-3/2 ≤ x
Combining the results from both inequalities:
-3/2 ≤ x < 5

Step-by-step explanation: The given equation is
[tex]2|7-7x|=2x+4.[/tex]
We are given to solve this equation and also find its extraneous solution.
The solution is as follows:
[tex]2|7-7x|=2x+4\\\\\Rightarrow |7-7x|=x+2\\\\\Rightarrow 7-7x=x+2,~~~~~-7+7x=x+2\\\\\Rightarrow 8x=5,~~~~~~~~~~~~~~~~\Rightarrow 6x=9\\\\\\\Rightarrow x=\dfrac{5}{8},~~~~~~~~~~~~~~~~~\Rightarrow x=\dfrac{3}{2}.[/tex]
now, for [tex]x=\dfrac{5}{8}[/tex], we have
[tex]L.H.S.=2|7-7\times \dfrac{5}{8}|=\dfrac{21}{4},\\\\R.H.S.=2\times\dfrac{5}{8}+4=\dfrac{21}{4}.[/tex]
So, this solution is not extraneous.
For [tex]x=\dfrac{3}{2}[/tex], we have
[tex]L.H.S.=2|7-7\times \dfrac{3}{2}|=7,\\\\R.H.S.=2\times\dfrac{3}{2}+4=7.[/tex]

A woman at a point A on the shore of a circular lake with radius r=4 wants to arrive at the point C diametrically opposite A on the other side of the lake in the shortest possible time. She can walk at the rate of 10mph and row a boat at 5mph. What is the shortest amount of time it would take her to reach point C?
I'm not sure where to start... :(
The shortest possible time for the woman to reach the point diametrically opposite on the other side of the lake is 0.8 hours, regardless if she chooses to walk around the lake or row across it.
Explanation:The subject of this problem is about distance and speed, and involves optimizing the total travel time. The woman has two main options: to walk around the lake or to row across it. The diameter of the lake is 2r=8, if she walked, it would take her 8/10=0.8 hours to reach point C.
However, if she rows straight across the lake, the distance is the radius of the lake, which is 4 miles. The time taken to row across the lake is therefore 4/5=0.8 hours.
So, both options take the exact same time of 0.8 hours. Therefore, the shortest amount of time it would take for her to reach point C is 0.8 hours whether she chooses to walk around the lake or row across it.
