Answer:

(i) To calculate the present value of 6 months of rent for the first apartment, we can use the formula PV = FV / (1 + r)^n, where PV is the present value, FV is the future value (6 months of rent, or $900 x 6 = $5400), r is the interest rate (8% converted to a monthly rate, or 0.08/12 = 0.0067), and n is the number of periods (6 months). So, PV = $5400 / (1 + 0.0067)^6 = $4911.46

(ii) To find the range of rent for the new apartment such that Lee would switch, we need to find the monthly rent that would result in a present value equal to or greater than $4911.46. Using the same formula, we can solve for the monthly rent (R) by setting PV equal to $4911.46 and n equal to 6. So, $4911.46 = R*(1+0.0067)^6. Solving for R, we get that the monthly rent must be between $732.32 and $766.58 in order to be more favorable than the first apartment.

Answer:

The area of the first lawn is 64 = 24 square meters.

The area of the second lawn is 6 times bigger, so it is 246 = 144 square meters.

As the second lawn has the same width as the first one, 4 meters, we can calculate the length of the second lawn by dividing the area of the second lawn by its width.

So, the length of the second lawn is 144/4 = 36 meters.

Answer:

Greg borrowed $20,000.

Step-by-step explanation:

To calculate the principal (the amount borrowed), we can use the formula for simple interest:

I = Prt

where I is the interest, P is the principal, r is the annual interest rate, and t is the time in years.

Given that:

I = 1400

r = 7% (expressed as 0.07)

t = 4

P = I / (r * t) = 1400 / (0.07 * 4) = $20,000

Therefore, Greg borrowed $20,000.

Using the definition of the derivative, the derivative of the function is f'(t) = 5t + 6. The domain of the function and its derivative are both the set of all real numbers.

The derivative is a concept in calculus that represents the rate of change or the slope of a function at a specific point. It is defined as the limit of the difference quotient of the function as the interval between the two points approaches zero. Mathematically, the derivative of a function f(x) at a point x is represented as f'(x) and can be expressed as:

f'(x) = lim h -> 0 [f(x + h) - f(x)]/h

where h is the interval between the two points.

The derivative is a fundamental tool for analyzing and understanding the behavior of functions, including their local maxima, minima, and inflection points, as well as for solving problems in physics and engineering.

The derivative of the function f(t) = 2.5t² + 6t can be found using the definition of the derivative:

f'(t) = limit as h -> 0 of [f(t + h) - f(t)]/h

= limit as h -> 0 of [2.5(t + h)² + 6(t + h) - (2.5t² + 6t)]/h

= limit as h -> 0 of [2.5t² + 5ht + 2.5h² + 6t + 6h - 2.5t² - 6t]/h

= limit as h -> 0 of [5ht + 2.5h² + 6h]/h

= limit as h -> 0 of [5t + 2.5h + 6]

= 5t + 6

The domain of the function f(t) = 2.5t^2 + 6t is all real numbers. The domain of its derivative f'(t) = 5t + 6 is also all real numbers.

Answer:

To find out how many of the first 76 slices sold during lunch tomorrow should be pepperoni pizza, we can use the information provided about the proportion of pepperoni pizza slices sold today. We can use the following formula to calculate the expected proportion:

(number of pepperoni slices / total number of slices) * 100

Plugging in the numbers we have:

(44 / (44 + 15 + 29)) * 100 = 44 / 88 * 100 = 50%.

So we can expect 50% of the first 76 slices sold during lunch tomorrow to be pepperoni pizza slices, which is equivalent to:

76 slices * 50% = 38 slices

Therefore, we expect 38 of the first 76 slices sold during lunch tomorrow should be slices of pepperoni pizza.

The height of the rectangular prism is 2x^3

The volume of a rectangular prism is given by the product of its length, width, and height.

We know that the volume is 48x^8, so we can write an equation:

48x^8 = (4x^2)(6x^3)(h)

We can simplify the left side:

48x^8 = 24x^5 * h

And divide both sides by 24x^5 to find the height:

h = 48x^8 / 24x^5 = 2x^3

So the height of the rectangular prism is 2x^3

Simply draw vertical lines down the graph, or you don't have to if you can imagine it. None of the vertical lines can pass through any points twice. So in this case, look at (6, 4) and (6, 6). Draw a vertical line down at x=6. It fails the vertical line test because the vertical line passes through the two points.

Rotation of a quarter circle to form an hemisphere, by integration is presented as follows;

The volume of the cone carrying the hemisphere = (1/3)×π×1²×4 = (4/3)·π

The volume of the ice cream = The volume of the cone + The volume of the hemisphere

Therefore;

Volume of the ice cream = (2/3)·π + (4/3)·π = (6/3)·π = 2·π  ≈ 6.3

Answer:

C

Step-by-step explanation:

How do we get from 4 to 20? Multiply 4 * 5 = 20.

How do we get from 20 to 100? Multiply 20 * 100.

Thus the answer is C where you multiply 5 by the previous function output.

I saw this pattern from experience, however you could also solve another way:

Simply plug in to the given functions in each answer choice.

For example, A:

f(1) = 4

f(n) = 16 * f(n - 1), for n >= 2

Now test values of n and check if they match the table.

f(1) = 4. This matches the table

f(2) = 16 * f(2 - 1) = 16 * f(1) = 16 * 4 = 64. This does not match the table.

You continue this process with the rest of the answer choices until you find a function, f(n), that gives the correct output of the table.

Let's start by converting this word problem into math equations... This will make it much easier to choose an approach to the problem!

Write equations for both Dave and Angie. We will use the variables P for slices of pizza, and W for bottles of water bought.  

(1) Dave: [tex]3P+2B=12.75[/tex]

(2) Angie: [tex]1P+3B=7.75[/tex]

Now that we have these equations, it's much easier to tell that this is a system of two equations (two equations, two unknowns). To solve this system, we can use a variety of different methods. For this problem, let's use the Elimination method (removing one variable from the equation.

Start by multiplying (scaling) Angie's equation by a factor of -3, so that we will be able to remove Pizza slices from the equation:

(3) [tex]-3(1P+3B=7.75) \equiv -3P-9B=-23.25[/tex]

Now, let's add Angie's new equation to Dave's original:

[tex]-7B=-10.5[/tex]

Notice that we now only have one variable in this simple equation. This is very easy to solve!

Simplify:

[tex]B=1.5[/tex]

Now that we have the price for a bottle of water, we can substitute this value into either (1) Dave's or (2) Angie's original equation to find the price for a slice of Pizza (P). I will substitute into (1) Dave's equation:

Substitute:

[tex]3P+2(1.5)=12.75[/tex]

Simplify:

[tex]3P=9.75[/tex]

Divide:

Finally, we have reached our conclusion... A slice of Pizza costs $3.25 and a bottle of water costs $1.5 at the concession stand! Let me know if you have any questions or want to learn other ways of solving this problem!

The distance between the two points is 13 units.

Distance between two points is the length of the line segment that connects the two points in a plane.

The formula to find the distance between the two points is usually given by d=√((x2 – x1)² + (y2 – y1)²)

point 1 (1, 4): x1 = 1 , y1 = 4

point 2 (6, 16): x2 = 6 , y2 = 16

Using the formula with the given values:

d=√((x2 – x1)² + (y2 – y1)²

d=√((6 – 1)² + (16 – 4)²)

d=√(5² + 12²)

d = √169

d = 13 units
