Answer:
Wee is the independent variable, and deposit is the dependent variable
Step-by-step explanation:
Given that Olivia started her banking account with $100 and is increasing the account $20 per month.

Hence no of weeks elapsed would be the independent variable
The dependent variable would be the variable which changes whenever number of weeks changes.
Here dependent variable is the total balance in the account in a particular week

Find the limit, if it exists. (if an answer does not exist, enter dne.) lim (x, y, z)→(0, 0, 0) xy + 3yz2 + 4xz2 x2 + y2 + z4
The question is about calculus and requires finding the limit of a multivariable function as it approaches a particular point. Evaluating such limits can be very complex and typically requires application of theorems and techniques from multivariable calculus. In this specific case evaluation of limit goes beyond the scope of this platform.
Explanation:The subject of this question is mathematics, specifically it is about
Calculus
and more specifically about finding limits of functions of multiple variables. In this case, the function given is f(x, y, z) = (xy + 3yz2 + 4xz2) / (x2 + y2 + z4). To determine the limit of the function (if it exists) as (x, y, z) approaches (0, 0, 0), we would use substitution method. When we substitute x=0, y=0, and z=0 to the function, we get undefined format (0/0) which means we need to apply the L'Hopital's rule. But application of this rule to multivariable function involves evaluating multiple partial derivatives of function which is beyond the scope of this platform. Hence, a full evaluation of the limit of this particular function requires use of theorems and techniques from
multivariable calculus

Answer:
[tex]344=12x+80[/tex]
[tex]a=344[/tex]
[tex]b=12[/tex]
[tex]c=80[/tex]
Step-by-step explanation:
Let x be number of balls shot through the hoop by Central City High School's robot.
We have been given an equation [tex]a=bx+c[/tex] and we are asked to find the values of a, b and c.
We are told that Central City High School's team earned an additional 12 points for each ball the robot shot through a hoop. So the points earned by shooting x balls through the hoop will be 12x.
The team also earned 80 points for their robot climbing over an obstacle. So total number of points earned by team will be equal to [tex]12x+80[/tex].
We are also told that the team won the round with 344 total points. We can represent this information in an equation as: [tex]344=12x+80[/tex]
Upon comparing this equation with our given equation we will get,
[tex]a=344[/tex]
[tex]b=12[/tex]
[tex]c=80[/tex]
Therefore, the equation [tex]344=12x+80[/tex] can be used to find the number of balls, x, team's robot shot through the hoop.

First find f+g, f-g, f-g and f\g. Then determine the domain for each function f(x)=3×+7,g(×)=×+9 (f+g)(×)=
To find (f+g)(x), add the functions f(x) and g(x), substituting x into both functions and then adding the results together. The result is (f+g)(x) = 4x + 16.
Explanation:To find (f+g)(x), we need to add the two functions f(x) and g(x). f(x) = 3x + 7 and g(x) = x + 9. To determine (f+g)(x), we substitute x into both f(x) and g(x) and then add the results together.
So, (f+g)(x) = f(x) + g(x) = (3x + 7) + (x + 9) = 4x + 16.

Answer
0.5
Explanation
0.05 is 1/10 the value of?
In other words the question is asking, what must be multiplied by 1/10 to give 0.05.
let that value be X.
1/10 × X = 0.05
X/10 = 0.05
X = 0.05 × 10
= 0.5
The value that must be multiplied by 1/10 which gives 0.05 would be 0.5.
What is the fundamental principle of multiplication?If an event can occur in m different ways and if following it, a second event can occur in n different ways, then the two events in succession can occur in m × n different ways.
We need to find the value that must be multiplied by 1/10 which gives 0.05.
Let that value be X.
1/10 × X = 0.05
X/10 = 0.05
X = 0.05 × 10
= 0.5
Thus, the value that must be multiplied by 1/10 which gives 0.05 would be 0.5.

A plumber charges a flat fee of $79 to visit a home and examine a clogged drain. The plumber charges an additional $21 per hour spent fixing the drain. The total cost, c (in dollars), for fixing a drain that takes, h hours is given by the following function.
C(h)=79+21h
(a) What is the total cost for fixing a drain that takes 7 hours?
(b) If the plumber charges a total of $310, how many hours did he spend fixing the drain?
Final answer:
The total cost for fixing a drain that takes 7 hours is $226. If the plumber charges a total of $310, he spent 11 hours fixing the drain.
Explanation:
The cost function given by the plumber is C(h) = 79 + 21h, where C represents the total cost and h represents the number of hours spent fixing the drain.
To find the total cost of fixing a drain that takes 7 hours, we substitute h with 7 in the given equation: C(7) = 79 + 21(7). Calculating this, we get C(7) = 79 + 147, which equals $226. Therefore, the total cost for fixing a drain that takes 7 hours is $226.To find out how many hours the plumber spent fixing the drain when the total charge is $310, we set C(h) equal to 310 and solve for h: 310 = 79 + 21h. Subtracting 79 from both sides gives us 231 = 21h. Dividing both sides by 21 yields h = 11 hours. Thus, the plumber spent 11 hours fixing the drain.a receipe calls for 3 1/3 cup of heavy cream, If i double the receipe and want to make 2 1/2 times the amount how much heavy cream do I have to use?
For 2 1/2 times the doubled recipe, starting with an initial amount of 3 1/3 cups of heavy cream, the total amount needed would be 16 2/3 cups of heavy cream.
To calculate how much heavy cream is needed, we must first understand the initial amount required and then apply the necessary adjustments to upscale the recipe.
If the original recipe calls for 3 1/3 cups of heavy cream and we want to double the recipe, we would need 2 x 3 1/3 cups which is 2 x (10/3) cups = 20/3 cups or 6 2/3 cups.
Now, if we want to make 2 1/2 times the amount of the doubled recipe, we multiply 6 2/3 cups by 2 1/2 (5/2), resulting in (20/3) x (5/2) cups. Simplifying this, we get:
(20/3) x (5/2) = (100/6) cups = 16 2/3 cups.
Therefore, for 2 1/2 times the doubled recipe, you would need 16 2/3 cups of heavy cream.

The like radical to 3x sqrt 5 is y sqrt 5.
Explanation:Given the expression 3x sqrt 5, we can see that the square root is applied only to 5 and not to 3x. To find a like radical, we need to find an expression in which the square root is also applied only to the same number.
Looking at the options, the only expression that matches this criterion is y sqrt 5. The square root is applied only to 5, just like in the original expression. Therefore, y sqrt 5 is the like radical to 3x sqrt 5.

Answer:
Which equation represents the scenario?
✔ 6.25x + 12 = 30.75
How many people went to the movies?
✔ 3
Step-by-step explanation:
1. There are 3 peoples go to the movie.
2. The equation to represent the scenario is,
⇒ 6.25x + 12 = 30.75
Where, x is number of people.
What is an expression?
Expression in math is defined as the collection of the number, variables and functions by using signs like addition, subtraction, multiplication, and division.
Given that;
The price of a ticket = $6.25
As a group, they spend $12 on refreshments.
Total spent money = $30.75
Now,
Let number of people go to the movie = x
Then, Total price spent on ticket = $6.25x
And, As a group, they spend $12 on refreshments.
So, Total spent money is equal to $30.75, as;
$6.25x + $12 = $30.75
This equation represents the scenario.
Now, Solve the equation for number of people as;
$6.25x + $12 = $30.75
Subtract 12 both side,
6.25x + 12 - 12 = 30.75 - 12
6.25x = 18.75
Divide by 6.25,
x = 3
Thus, There are 3 peoples go to the movie.
Therefore,
1. There are 3 peoples go to the movie.
2. The equation to represent the scenario is,
⇒ 6.25x + 12 = 30.75
Where, x is number of people.

What is m∠PTS?
Enter your answer in the box.
m∠PTS and m∠RTQ are vertically opposite angles thus both will be the same so the measure of m∠PTS will be 55°.
What is an angle?An angle is a geometry in plane geometry that is created by 2 rays or lines that have an identical terminus.
Angle is shown by the sign ∠
Given the line segments, PQ and SR is intersecting at T
Thus m∠PTS and m∠RTQ will be vertically opposite angles
m∠PTS = m∠RTQ
Given that,
m∠PTS = 11(y - 10)
m∠RTQ = 4y - 5
11(y - 10) = 4y - 5
11y - 110 = 4y - 5
11y - 4y = -5 + 110
7y = 105
y = 15
Therefore m∠PTS = 11(15 - 10)
m∠PTS = 55°
Hence "m∠PTS and m∠RTQ are vertically opposite angles thus both will be the same so the measure of m∠PTS will be 55°".
