A) Iker started running 24 laps on the track each week. This is mentioned in the question.
B) Iker ran 11 more laps each week.
C) The equation for this situation would be: y = 11x + 24
Determine the number of lapsTo find out how many more laps he ran each week, we can subtract the number of laps he ran on the first week from the number of laps he ran on the second week: 35 - 24 = 11 So, Iker ran 11 more laps each week.
To write an equation that models this type of growth, we can use the following formula: y = mx + b
Where y is the number of laps he runs, m is the number of additional laps he runs each week, x is the number of weeks, and b is the number of laps he started running.
In this case, m = 11 (the number of additional laps he runs each week) and b = 24 (the number of laps he started running).
So the equation for this situation would be: y = 11x + 24 This equation shows that the number of laps Iker runs each week (y) is equal to 11 times the number of weeks (x) plus the number of laps he started running (24).

A coffee shop sells its coffee for $2.50 per cup.
In April they had total sales of $31,250.
In May they sold 10,150 cups of coffee.
Their total sales in June was the average of what they sold in April and May.
How many cups of coffee were sold in April?
What was the total sales ($$$) for May?
How many cups of coffee were sold and what was the total dollars in sales for the month of June?
Answer:
Step-by-step explanation:
Let's call the number of cups sold in April "x".
The total sales in April were $31,250, so we can set up an equation to find x:
2.50 * x = 31,250
Dividing both sides by 2.50, we get:
x = 12,500
So in April, 12,500 cups of coffee were sold.
The total sales in May were 10,150 cups * $2.50 per cup = $25,375.
The average of the sales in April and May was $31,250 + $25,375 / 2 = $28,312.50.
So in June, they sold $28,312.50 / $2.50 per cup = 11,250 cups of coffee.
Answer: There were 12,500 cups sold in April. In May they made $25,375. They sold 11,325 cups and made $28,312.50 in June.
Step-by-step explanation:
To find the cups of coffee sold in April, we will divide the total sales by price per cup.
$31,250 / $2.50 = 12,500 cups
To find the total sales for May, we will multiply the cups sold by the price per cup.
10,150 * $2.50 = $25,375
If they sold the average of April and May in June, we will find the average of April and May.
12,500 cups in April + 10,150 cups in May = 22,650
22,650 / 2 = 11,325 cups sold in June
Then, to find the dollar sales, we will multiply by the price per cup again.
11,325 * $2.50 = $28,312.50

B. Multiply the top equation by 3 and the bottom equation by-2.
C. Multiply the bottom equation by 2.
D. Multiply the top equation by -3.
SUBMIT
Answer: C
Step-by-step explanation:
The two variables need to be eliminated. You can do this by multiplication or subtraction.
Multiply by -3 to the top equation will eliminate the x variable in the system
-3(2x - 4y = 5)
6x - 3y = 10
==> -6x + 12y = -15
6x - 3y = 10
adding a top with a bottom will eliminate the x
==> -6x + 6x = 0, 12y + (-3y) = 9y, -15 + 10 = -5
If the sky is clear then we can see the stars at night
Yes, that is correct; If the sky is clear, we are able to see the stars at night.
A star is a celestial body that maintains its shape thanks to its own gravity. Also, a star has the ability to generate its own light, an example of a star is the Sun.
The stars are always there, but during the day, the brightness of the sun makes it impossible for us to see them. However, at night when the sun is no longer visible, the stars become visible to us. This is why we can see the stars in the sky at night when there are no clouds obstructing our view.

What would the inverse function tell us?
O The minimum number of visitis
O The visits for a cost of $60
O The cost in terms of visits "m"
O The number of visits made for a costs of "C"
Option (4): The inverse of the function tells us the number of visits m that can be made for a cost of c.
What is meant by the inverse of a function?
A function takes in values, applies specific operations to them, and produces an output. The inverse function acts, agrees with the outcome, and returns to the initial function.
A function that can reverse into another function is known as an inverse function. In other words, the inverse of a function "f" will take y to x if any function "f" takes x to y. When a function is written as "f" or "F," its inverse is written as " f ⁻¹ " or " F ⁻¹."
Given a function,
c(m) = 60 + 10m
where c = cost of visiting the gym
m = number of visits
Then the Inverse function is:
c(m) - 60 = 10m
m = (c(m) - 60) / 10
Therefore the inverse of the function tells us the number of visits m that can be made for a cost of c.

what is unit vector notation ?
Unit vector notation is a way of representing vectors in which magnitude of vector is equal to 1. A vector is mathematical object that has both magnitude (length) and direction, and can be represented as an arrow.
In unit vector notation, a vector is represented as a combination of a scalar (a numerical value) and a unit vector (a vector with a magnitude of 1 in the same direction).
The most common notation for unit vectors is to use a hat symbol (^) to indicate that a vector is a unit vector. For example, if we have a vector v, then its corresponding unit vector in the same direction would be represented as v. The unit vector in the x-direction is typically denoted as i, and the unit vector in the y-direction is denoted as j.
Unit vector notation is useful in many applications, including physics and engineering, where it is used to describe the direction of forces, velocities, and accelerations. It is also commonly used in computer graphics and game development, where it is used to represent the direction of movement or rotation of objects in a 3D space.

What does the size of stiffness matrix depend on?
the size of the stiffness matrix depends on the number of degrees of freedom and the type of elements used in the analysis. It is an important tool in structural mechanics and engineering for analyzing the behavior and performance of structures under different loading conditions.
In structural mechanics and engineering, the stiffness matrix is a mathematical representation of the stiffness of a structure, which relates the forces and displacements of the structure. The size of the stiffness matrix depends on several factors, including the number of degrees of freedom and the type of elements used in the analysis. The number of degrees of freedom (DOF) in the system determines the size of the stiffness matrix. DOF refers to the number of independent displacements or rotations that a structure can undergo in response to external forces. For example, a simple beam structure might have two DOF (vertical displacement and rotation), while a more complex structure such as a truss or frame might have many more DOF. The size of the stiffness matrix also depends on the type of elements used in the analysis. Different types of elements have different degrees of freedom and stiffness properties, which affect the size and shape of the stiffness matrix. For example, a truss element has two DOF and a constant axial stiffness, while a beam element has four or six DOF and variable stiffness properties that depend on its geometry and material properties.
In summary, the size of the stiffness matrix depends on the number of degrees of freedom and the type of elements used in the analysis. It is an important tool in structural mechanics and engineering for analyzing the behavior and performance of structures under different loading conditions.
