The expression that represents the total cost of buying and shipping the baseball cards,

= 6(1.75) + 5(9.5) + 2(20.5) + 4

Combining objects and counting them as one big group is done through addition. In arithmetic, addition is the process of adding two or more integers together. Addends are the numbers that are added, and the sum refers to the outcome of the operation.

Given:

Jake is buying baseball cards for his brother in college.

The price of a card is based on its condition.

The table shows the total cost of x number of cards for each condition.

He buys 6 that are in fair condition, 5 that are in good condition, and 2 that are in excellent condition.

The shipping cost for the baseball cards is $4.00.

The expression that represents the total cost of buying and shipping the baseball cards,

= 6(1.75) + 5(9.5) + 2(20.5) + 4

= 10.5 + 47.5 + 41 + 4

= 103

Therefore, the total cost is $103.

The axis of symmetry for a parabola in the form of f(x) = a(x - h)^2 + k is x = h.

For f(x) = 4x^2 - 1, the axis of symmetry is x = 0.

For g(x) = x^2 - 8x + 5, the axis of symmetry is x = 4.

For h(x) = -3x^2 - 12x + 1, the axis of symmetry is x = -4/3

So, the ranking from least to greatest based on their axis of symmetry would be:

h(x) = -3x^2 - 12x + 1 with x = -4/3

g(x) = x^2 - 8x + 5 with x = 4

f(x) = 4x^2 - 1 with x = 0

Answer: 8.46 years

Step-by-step explanation:

To find out how long it will take for the account value to reach $25,300, you would need to use the formula:

A = P(1 + r/n)^(nt)

Where:

A is the final amount (25,300)

P is the initial amount (3,100)

r is the annual interest rate (7.25%)

n is the number of times the interest is compounded per year

t is the number of years

In this case, we can assume that the interest is compounded annually, so n=1.

We can then plug in the values and solve for t:

25,300 = 3,100(1 + 0.0725)^t

t = (ln(25,300/3,100)) / (ln(1 + 0.0725))

t ≈ 8.46 years

So it would take approximately 8.46 years, rounded to the nearest year.

An example of Equivalent Expressions in math is

2(x² -1 ) - 1 and 2x² - 3 , because the value both remains same for any value of x.

Equivalent expressions are defined as the expressions that work the same even though they look different. Two expressions are equivalent when they can be simplified to the same third expression or if one of the expressions can be written like the other. In other words we can say that two algebraic expressions are equivalent, then the two expressions have the same value when we plug in the same value(p) for the variable(x). Let's consider an example for better understanding, let 2( x² - 1) - 1 be an algebraic expression and we want to determine its equivalent expression.

Simplify, the expression, 2( x² - 1) - 1 --(1)

=> 2x² - 2 -1

=> 2x² - 3 --(2)

if x= 1 , 2( x² - 1) - 1 = 2( 1² - 1) - 1 = -1 and 2x² - 3 = 2(1)² - 3 = -1

Now, expression (1) and (2) looks different but we get same value when substitute the same value of variable(x). By using definition, both expressions are equivalent.

The equation of the circle in the form of x^2 + y^2 + Px + qy + c = 0

The standard form of the equation of a circle is (x - h)^2 + (y - k)^2 = r^2, where (h, k) is the center of the circle, and r is the radius.

Given the center of the circle is (-2,3) and the radius is 3cm.

Emilia and her brother used the computer for 1.5 hours.

When Emilia and her brother need to use the family computer for their homework, they have agreed to share the computer equally. On this particular evening, they both needed the computer for 3 hours. To understand how much time each of them used the computer, we need to divide the total time by the number of users.

Dividing the total time of 3 hours by the number of users which is 2, we get 3 hours / 2 = 1.5 hours. This means each person, Emilia, and her brother, use the computer for 1.5 hours each.

Prospective observational studies involve collecting data from participants before an event or outcome occurs, while retrospective observational studies collect data after the event has already taken place.

A prospective observational study is a type of observational study that involves collecting data from participants before an event or outcome occurs. This type of study is used to predict and measure outcomes in the future.

In this type of study, the researcher can control the variables, such as when and how the data is collected, and can also observe the effects of any changes in the environment.

On the other hand, a retrospective observational study is a type of observational study that involves collecting data after an event or outcome has already taken place. This type of study is used to study the causes of a given outcome.

In this type of study, the researcher looks back in time and collects data from the past. This type of study is more limited than a prospective observational study, since the researcher cannot control the variables of the study or observe any changes in the environment.

If, Δ ≠ 0, then we can say that the system of equations is consistent and will give us a unique solution.

However, we are concerned with the case when Δ = 0.

If Δ = 0, then we need to find the values of Δ₁, Δ₂, and Δ₃.

If at least one of the three Δ₁, Δ₂, and Δ₃ is not equal to 0 then we say that the equation is consistent.

Now if,

Δ₁ = Δ₂ = Δ₃ = 0, then we need to do the following:-

We need to take any 2 equations and get the values of x and y in terms of z.

Now we need to substitute the value of x and y for these values in the third equation.

The speed of a point on the wheel rim is 35000π cm/s (2500 rev/min and 14cm diameter).

what is circumference ?

Circumference is the distance around the edge of a circle. It can be calculated using the formula: C = 2πr, where C is the circumference and r is the radius of the circle.

To express the speed of a point on the rim of the wheel in centimeters per second, we first need to find the circumference of the wheel using the diameter. The circumference can be found using the formula: C = 2πr, where C is the circumference and r is the radius of the wheel.

Since the diameter is 14cm, the radius of the wheel is 14/2 = 7cm.

Therefore, the circumference of the wheel is: C = 2π(7) = 14π cm

Next, we need to find the distance traveled by a point on the rim of the wheel in one revolution. This distance is equal to the circumference of the wheel.

So, the distance traveled by a point on the rim of the wheel in one revolution is: 14π cm

To find the speed in centimeters per second, we need to multiply the distance traveled in one revolution by the number of revolutions per minute.

The wheel rotate 2500 revolution per minute.

The speed of a point on the wheel rim is 35000π cm/s (2500 rev/min and 14cm diameter).
