TLDR: The answer is -2.
What you have here is a function with a point on the graph. It is understood that “x” represents the input and “y” represents the output, so we’re looking for the right “x” that will give y = 1/100.
To start, we can substitute the y-value into the function like this:
y = 10^x
1/100 = 10^x
From here, we can take two different pathways; one requires conceptual knowledge while the other relies on the knowledge of logarithms.
Conceptual
For the conceptual, we know that 100 = 10^2, so 1/100 is the same as 1/10^2. We also know that the inverse of a fraction is the same as the number to the negative of its power (for example, 1/2 is equal to 2^-1), so we know that 1/10^2 is the same as 10^-2. So far, we have learned that:
1/100 = 10^x
1/10^2 = 10^x
10^-2 = 10^x
So, to satisfy this, “x” must equal -2.
Logarithms
For logarithms, we can use powers and math to actually calculate the value of “x”. We know that:
1/100 = 10^x
To solve this, we need “x” to be by itself on one side of the equation. To do this, we can perform the inverse function of an exponent, which is a logarithm. In this case, the base of 10^x is 10, so we need a “base 10” logarithm to solve this function. Apply this function to both sides and simplify:
1/100 = 10^x
log10(1/100) = log10(10^x)
log10(1/100) = x
The log10 function is the inverse of 10^x, so they cancel out to leave “x”. Plug log10(1/100) into a calculator, and you find that x = -2.
Hope this helps!

Jayne stopped to get gas before going on a road trip. The tank already had 4 gallons of gas in it. Which best describes why the graph relating the total amount of gasoline in the tank, y, to the number of gallons that she added to it, x, will be continuous or discrete?
The graph will be continuous because the amount of gas that she added to the tank does not need to be an integer amount.
The graph will be continuous because we are not told a maximum value for the amount of gas.
The graph will be discrete because there are already exactly 4 gallons of gas in the tank, so to fill it up will take a whole number of gallons of gas.
The graph will be discrete because there is an end to the amount of gas she can use, as the tank will be completely full at some point.

A plane is to be loaded with bottles of water and medical supplies to be sent to victims of an earthquake. Each bottle of water serves 10 people and each medical kit aids six people. The goal is to maximize z, the total number of people helped, where z = 10x + 6y, and x is the number of bottles and y is the number of medical kits. Using the constraints of the situation (plane weight and volume capacities) the shaded region is in the graph is obtained. Which vertex of the region represents the solution to the maximization problem?
Answer:
The vertex that maximize the problem is (2,000,4,000)
Step-by-step explanation:

The vertex of the shaded region are
A(0,0), B(4,000,0),C(2,000,4,000), D(0,6,000)
Substitute the value of x and the value of y of each vertex in the z equation to find the solution
case A) A(0,0)
[tex]z=10(0)+6(0)=0[/tex]
case B) B(4,000,0)
[tex]z=10(4,000)+6(0)=40,000[/tex]
case C) C(2,000,4,000)
[tex]z=10(2,000)+6(4,000)=44,000[/tex]
case D) D(0,6,000)
[tex]z=10(0)+6(6,000)=36,000[/tex]
therefore

it's possible for a table to display yes/no and numberic data at the same time
Answer:
yea it can
Step-by-step explanation:
Final answer:
A table can simultaneously display yes/no (Boolean) and numeric data. Yes/No fields in databases are often checkboxes representing binary choices, while other columns can store numeric data. The data types assigned to these fields determine how they are sorted and displayed in the table.
Explanation:
Yes, it is entirely possible for a table to display both yes/no and numeric data at the same time. The yes/no data is often referred to as binary, Boolean, or Yes/No datatype, and in databases, it commonly appears as a checkbox. These Yes/No fields contain only two possible values, such as Yes/No, True/False, or On/Off. On the other hand, the numeric data represents quantitative information that can be measured and written down with numbers.
Tables are quite versatile and can conveniently organize complex numerical information, alongside qualitative categories, in a structured format using rows and columns. For example, a table can be used to compare different models of a product using criteria represented by both text and numbers, such as product features ('Yes' for having a feature and 'No' for not having it) and specifications like price or weight (numeric data).
It's important to keep in mind that when designing a database, every field is assigned a datatype based on what type of data it holds. For fields containing text, a 'text' datatype is used; whereas for fields containing numeric values, a 'number' datatype is chosen. The datatype affects how the data is sorted and processed within the table.

James is 1.63 meters tall. Write James’s height in word form. Explain how you Found your answer.
Answer:
James is 1 meter and 63 centimeters tall
Step-by-step explanation:
James is 1 meter and 63 centimeters tall. The first step will be to subtract 1 from his height;
1.63 - 1 = 0.63 meters
The 1 subtracted is equivalent to 1 meter. The next step is to convert the remaining height in meters to centimeters by multiplying by 100;
0.63 * 100 = 63 centimeters
We can thus say, James is 1 meter and 63 centimeters tall or equivalently 163 centimeters tall

HELP NEEDED ASAP!! What is the length of AC
Answer:
(144) is the homogeneous mixture
Answer:
Ac = 144
Step-by-step explanation:
From the figure we can see two similar triangles,Ratio of sides of similar triangles are equal.
To find the value of x
From the figure we can write,
7/84 = x/(156 - x)
1/12 = x/(156 - x)
156 - x = 12x
13x = 156
x = 156/13 = 12
To find the value of AC
AC = 156 - x
= 156 - 12
= 144
Therefore AC = 144

V = ( π / 4 ) ( d² ) L
V = ( π / 4 ) ( 10² ) 64 = 1600π cubic meters
The volume of the second figure:-
V = ( π / 4 ) ( d² ) L
V = ( π / 4 ) ( 32² ) 20 = 5120π cubic meters
The volume of the third figure:-
V = ( π / 4 ) ( d² ) L
V = ( π / 4 ) ( 10² ) 128 = 3200π cubic meters
We can see that the volume of the third figure is maximum.
Therefore Option 2 in the given figure will have a maximum volume of 5120π cubic meters.

Need this to graduate. Math 3- 10 points. Find the function!
The answer is:
The fourth option,
[tex](f-g)(x)=11x[/tex]
Why?To solve the problem, we must remember the following property of the functions:
Subtraction of functions:
We have that,
[tex](f-g)(x)=f(x)-g(x)[/tex]
We are given the functions:
[tex]f(x)=4x+3[/tex]
and
[tex]g(x)=3-7x[/tex]
So, calculating we have:
[tex](f-g)(x)=f(x)-g(x)[/tex]
[tex](f-g)(x)=(4x+3)-(3-7x)[/tex]
[tex](f-g)(x)=4x+3-3+7x[/tex]
[tex](f-g)(x)=4x+7x+3-3=11x[/tex]
Hence, the answer is the fourth option,
[tex](f-g)(x)=11x[/tex]
Have a nice day!
Answer:
(D) (f-g)(x) = 11x
Step-by-step explanation:
You have:
f(x) = 4x + 3
g(x) = 3 - 7x
You want to do f(x) - g(x)... you simply do the operation on their definition...
f(x) - g(x) = 4x + 3 - (3 - 7x) = 4x + 3 - 3 + 7x = 11 x + 0
So, (f-g)(x) = 11x
You can verify it by placing a value for x in both equations. Let's take x = 3
f(x) = 4x + 3 = 4(3) + 3 = 15
g(x) = 3 - 7x = 3 - 7(3) = -18
f(x) - g(x) = 15 - -18 = 33
(f - g)(x) = 11x = 11 (3) = 33
Yes, (f(x) - g(x)) = (f - g)(x) = 33
The simplest form of 3 cube root of 162 is a3 cube root b
Answer:
[tex]3 \sqrt[3]{162} = 3 \sqrt[3]{27} \sqrt[3]{6} = 3(3 \sqrt[3]{6} ) = 9 \sqrt[3]{6} [/tex]
Final answer:
The simplest form of 3 cube root of 162 is 9 cube root 2, with a=9 and b=2 after factoring out the perfect cube within 162.
Explanation:
The student has asked about simplifying the expression 3 cube root of 162 into the form a3 cube root b. The cube root of 162 can be simplified by factoring out cubes. The number 162 is equal to 2 * 81, where 81 is a perfect cube (3³). Thus, we can rewrite 162 as 2 * 3³. When taking the cube root, the cube root of 3³ is 3, and it comes out of the cube root symbol leaving us with 2 inside the cube root. Multiplying this by 3 outside the cube root, we get:
3 * 3 cube root 2 = 9 cube root 2
Therefore, the expression in its simplest form is 9 cube root 2, which follows the format a3 cube root b with a=9 and b=2.

Answer:
None of them.
Step-by-step explanation:
you want to find the least value of x for which f(x)>g(x). Then replacing both expressions we have
[tex]4x>5x+2\rightarrow -2>5x-4x=x[/tex] . This means that for f to be greater than g, x should be less than -2. Since we are considering x>0, given that it represents years (which are always positive), the question does not have a correct answer.
The point (-3,4) is reflected across the x-axis. What is the coordinates of its new location?
Semd a pic of a graph bc I dont have paper
The point (-3,4) when reflected across the x-axis results in new coordinates (-3, -4), changing the sign of the y-coordinate.
The question asks for the new coordinates of a point after being reflected across the x-axis. Reflecting a point across the x-axis changes the sign of the y-coordinate but leaves the x-coordinate unchanged. Therefore, if we have a point (-3, 4) and we reflect it across the x-axis, the x-coordinate remains -3, and the y-coordinate, which is 4, will become -4, resulting in the new coordinates (-3, -4).
