Taylor took out a 1,500$ discounted loan calculated using a simple interest rate of 2.5% for a period of 4 years. How much money does Taylor receive initially?

Answers

The initial amount that Taylor receive initially is $1500.

How to calculate the value?

Based on the information given, the following can be illustrated:

Interest = 1500

Time = 4 years

Rate = 2.5%

Principal = Unknown

Interest = PRT/100

1500 = (P × 4 × 2.5)/100

150000 = 10P

Divide

P = 150000/100

P = 1500

The initial amount is $1500.

It takes you 53 seconds to walk from the first​ (ground) floor of a building to the third floor. How long will it take you to walk from the first floor to the sixth floor​ (at the same​ pace, assuming all floors have the same​ height)?

Answers

The time it takes to walk from the first floor to the sixth floor​ is 132.5 seconds.

What is a division?

The division is a process of splitting a specific amount into equal parts.

We have,

To walk from the first floor to the third floor it takes 53 seconds.

From the first floor to the third floor there are two floors.

So we can say that the number of seconds it takes to walk to one floor is 53/2 assuming that each floor has the same height.

We have,

= 53 / 2

= 26.5 seconds

There are 5 floors from the first floor to the sixth floor.

So the time it takes to walk from the first floor to the sixth floor is:

= 26.5 x 5

= 132.5 seconds

We can also say that,

132.5 seconds = 2.20 minutes = 2 minutes 12 seconds

Thus the time it takes to walk from the first floor to the sixth floor​ is132.5 seconds.

Compute the derivatives of the Michaelis Menten kinetics

Answers

We get the derivative of the function V = K x / k n + x as d v / d x = k / k n + 1.

We are given a function:

V = K x / k n + x

where K and k n are constants.

We need to find its derivative with respect to x

Derivative refers the rate of change of a function with respect to a variable.

Now differentiating with respect to x , we get that:

d V / d x = k / k n ( 1 ) + ( 1 )

d v / d x = k / k n + 1

Therefore, we get the derivative of the function V = K x / k n + x as d v / d x = k / k n + 1.

A right triangle is one that has an interior angle of 90 degrees. The hypotenuse, which is also the side of the right triangle that faces the right angle, is its longest side. The height and base make up the two arms of the right angle.

In a 45-45-90 right triangle the hypotenuse is always equal to the measure of one of the legs times √2 call "n" the measure of one of the legs

n√2=5

Plot the intercepts to graph the equation.
9x−4y=−36
Graph it

Answers

For the line 9x−4y=−36 we have:

x-intercept (-4, 0)

y-intercept (0, 9)

The graph of the line can be seen below.

How to graph the linear equation?

Here we have the linear equation:

9x - 4y = -36

First, the x-intercept is what we get when y = 0, then:

9x - 4*0 = -36

9x = - 36

x = -36/9 = -4

Then we have the point (-4, 0)

And the y-intercept is what we get when evaluate the variable x = 0, so:

9*0 - 4*y = -36

y = -36/-4 = 9

Then we have the point (0, 9)

Now just graph these two points, and connect them with a line, you will get the graph below.

Answers

The computation shows that the hours that they both have to work to have the same amount of money saved is 16 hours.

How to calculate the function?

Based on the information given, let the number of hours be represented by h

Therefore, the first function for Michael will be:

96 + 12h

The second function for Greg will be:

= 128 + 10h

Therefore, we'll equate both equations. This will be:

96 + 12h = 128 + 10h

12h - 10h = 128 - 96.

2h = 32.

h = 32/2

h = 16 hours.

The table shows how long it takes for Building
Brothers to build and renovate homes. If the
company has been renovating homes for
16 years, how many homes has it renovated? Renovate a house: 8 months

Answers

Since Building Brothers have been renovating homes for 16 years, the number of homes renovated is 24.

How is the number of homes determined?

We can use mathematical operations of addition, subtraction, division, and/or multiplication to determine the missing value.

The first effort is converting 16 years into months.  The product is divided by 8 months to arrive at the quotient of 24 homes that were renovated within 16 years.

Data and Calculations:

Time period = 16 years

Time spent to renovate a house = 8 months

12 months = 1 year

Total number of months spent = 192 months (16 x 12)

The number of renovations = 24 (192/8)

Thus, Building Brothers have renovated 24 homes within 16 years.

Using translation concepts, the graph of g(x) is given at the end of the answer.

What is a translation?

A translation is represented by a change in the function graph, according to operations such as multiplication or sum/subtraction either in it’s definition or in it’s domain. Examples are shift left/right or bottom/up, vertical or horizontal stretching or compression, and reflections over the x-axis or the y-axis.

Function f(x) is a concave up parabola with vertex at (1, -5). For the translation g(x) = f(x + 2), we have that the function is shifted two units left, as:

g(x) = f(x + 2) = (x + 2 - 1)² - 5 = (x + 1)² - 5.
