mark is going to work for his father’s pool cleaning business during the summer. mark’s father will pay him $5 each pool he helps clean. write an algebraic expression to determine how much mark will earn if he cleans n pools. then evaluate the expression for 15, 25, 35, or 45 pools
Answer:
Algebraic Expression: 5n
a. 5(15) = 75$
b. 5(25) = 125$
c. 5(35) = 175$
d. 5(45) = 225$
Step-by-step explanation:
If n represents the amount of pools Mark has cleaned, and he earns $5 for each pool, then 5n will be the algebraic expression. As n represents the number of pools he has cleaned, we need to plug in the given numbers to get the answer, hence [5(15), 5(25), 5(35), 5(45)]. Multiply $5 by the given numbers to get the amount of money Mark would earn if he cleaned the amount of pools.

Find the unknown side length, x. Write your answer in simplest radical form.
A. 3
B. 34
C. 6.
D. 41
Answer:
√41
Step-by-step explanation:
Considering the sides with lengths 48 and 52 units, we would use Pythagoras theorem to find the third side. Let that side be t
52² = 48² + t²
t² = 52² - 48²
= 2704 - 2304
= 400
t = √400
= 20
Considering the next triangle with sides t (20 units) and 12 units, again using the theorem
20² = 12² + y²
where y is the third side
400 = 144 + y²
y² = 400 - 144
= 256
y = √256
= 16 units
Considering the triangle with two sides given as 5 and 13 units, the third side (which is part of the 16 units calculated earlier)
13² = 5² + u²
where u is the 3rd side
169 = 25 + u²
u² = 169 - 25
u² = 144
u = √144
u = 12
The other part of the side of that triangle
= 16 - 12
= 4
Considering the smallest triangle whose sides are x, 5 and 4,
x² = 5² + 4²
= 25 + 16
= 41
x = √41
The vertices of a triangle in space are (x1,y1,z1),(x2,y2,z2), and (x3,y3,z3). Explain how to find a vector perpendicular to the triangle.Two Points and a Direction:To determine the direction of a vector joining a pair of points: (x1,y1,z1),(x2,y2,z2), it is necessary to subtract the components of one point minus the other in any order.Formally we can write: (x1,y1,z1),(x2,y2,z2)→⟨x2−x1,y2−y1,z2−z1⟩.
Answer: To find a vector perpendicular to the triangle, you can use the cross product of two vectors formed by subtracting two of the triangle's vertices. Specifically, if two vectors v1 and v2 are formed by subtracting one vertex from the other two, then their cross product v1 × v2 will be perpendicular to both v1 and v2, and therefore perpendicular to the triangle they form.
Mathematically, the cross product of two vectors in three-dimensional space is defined as:
v1 × v2 = ⟨y1z2 − z1y2, z1x2 − x1z2, x1y2 − y1x2⟩
So, to find a vector perpendicular to the triangle with vertices (x1,y1,z1), (x2,y2,z2), and (x3,y3,z3), you can choose any two vertices and compute their difference to get two vectors, and then take their cross product. For example, you could choose:
v1 = ⟨x2−x1,y2−y1,z2−z1⟩
v2 = ⟨x3−x1,y3−y1,z3−z1⟩
And then compute their cross product:
v1 × v2 = ⟨(y2−y1)(z3−z1) − (z2−z1)(y3−y1), (z2−z1)(x3−x1) − (x2−x1)(z3−z1), (x2−x1)(y3−y1) − (y2−y1)(x3−x1)⟩
This will give you a vector that is perpendicular to the triangle.

Given the equation of the parabola - 36y = ?
The focus of the parabola is:
(0,9)
(-9,0)
(0,-9)
Correct question is ;
Given the equation of the parabola x² = -36y
The focus of the parabola is:
Answer:
Option C - Focus = (0,-9)
Step-by-step explanation:
The equation of the parabola is:
x² = -36y
Thus, y = - x²/36
Using the vertex form,
y = a(x − h)² + k, to determine the values of a, h, and k.
We will have;
y = (-1/36)(x − 0)² + 0
Thus,
a = - 1/36
h = 0
k = 0
The distance (p) from the vertex to a focus of the parabola is gotten by using the following formula.
p = 1/4a
So, p = 1/(4*(-1/36))
p = - 1/(1/9)
p = -9
Now, The focus of a parabola can be found by adding p to the y-coordinate k if the parabola opens up or down.
Focus is (h, k+p)
Plugging in the relevant values, we have;
Focus = (0, (0 + (-9))
Focus = (0,-9)

The two equations of a system that can be used to find the ages of both girls are y - x = 6 and 3x - y = 0.
What is system of equations?A group of two or more equations that must be solved all at once is known as a system of equations. The objective is to determine the values of the variables that make both equations true in a system of two equations with two variables. These numbers represent the system of equations' answer. There are several ways to solve a system of equations, including substitution, elimination, and graphing. They are used to simulate and resolve issues in many branches of mathematics, science, engineering, and other disciplines.
Let us suppose the age of Celine = x.
Let us suppose the age of Cindy = y.
Given that, Celine is 6 years younger than her sister Cindy.
x = y - 6
She is also one third as old as Cindy.
x = 1/3y or y = 3x.
Substitute the value of y in equation 1:
x = 3x - 6
6 = 2x
x = 3
Substitute the value of x:
y = 3(3) = 9
Hence, the two equations that can be used to find the ages of both girls are y - x = 6 and 3x - y = 0.

Isabella opened and deposited $1000 in a 5% quarterly compound interest savings account. She deposits $25 in the account each month. Use an online savings calculator to find how much money will be in the account at the end of 5 years?
Answer:
4,620.77
Step-by-step explanation:
To calculate the final amount in Isabella's savings account at the end of 5 years, we need to take into account the initial deposit, monthly deposits, and quarterly compound interest.
Using the given information, we can break down the calculation into multiple steps:
Calculate the total number of quarters in 5 years: 5 years * 4 quarters per year = 20 quarters.
Calculate the interest rate per quarter: 5% annual interest rate / 4 quarters = 1.25% quarterly interest rate (expressed as a decimal, 0.0125).
Calculate the total amount of monthly deposits over 5 years: $25 per month * 12 months per year * 5 years = $1500.
Use an online savings calculator or the compound interest formula to determine the final amount in the account. The formula for compound interest is given by:
Final Amount = Initial Deposit + Monthly Deposits + (Initial Deposit + Monthly Deposits) * (1 + Quarterly Interest Rate)^(Number of Quarters)
Plugging in the values:
Final Amount = $1000 + $1500 + ($1000 + $1500) * (1 + 0.0125)^(20)
Using an online savings calculator or performing the calculation, the final amount in Isabella's savings account at the end of 5 years will be approximately $4,620.77.

Option a shows the correct placement of the data points on a scatter plot, with the x-axis representing the months and the y-axis representing the average maximum monthly temperature. The points are clearly organized in a sequence from January to December, with an upward trend in temperature from the winter months to the summer months, followed by a gradual decrease in temperature in the fall and winter months.
Option b has the correct range of temperatures, but the points are not arranged in a logical sequence and are scattered randomly across the graph. Option c also has a similar issue with random placement of points and does not reflect the actual values in the data set. Option d only has three points and does not represent the complete data set.
