Consider the function f(x)=x² + 7x. Form an expression for f(a). f(a)=​

Consider the function f(x)=x + 7x. Form an expression for f(a). f(a)=

Answers

The value of the expression f(a) is f(a) = a^2 + 7a, based on the given function f(x) = x^2 + 7x and the value x = a

How to form the expression for f(a)?

The given parameters in the question are:

f(x) = x^2 + 7x and

x = a as in f(a)

This means that the equation of the function f(x) is given as:

f(x) = x^2 + 7x

To calculate the value of the function f(a), we simply substitute a for x in the equation of the function f(x) = x^2 + 7x.

This means that we set x to a in the equation of the function f(x) = x^2 + 7x.

So, we have;

f(a) = a^2 + 7a

The above equation cannot be further simplified or expanded

So, we conclude that

Based on the given function f(x) = x^2 + 7x and the value x = a, the value of the expression f(a) is f(a) = a^2 + 7a

The storage capability of computers has been doubling every 5 years since the first computers were invented in the 1960s. If the first computer could store .5 megabytes, about how many megabytes can today's computers store? How long did it take for computers to store 100 megabytes?

Answers

It takes time of near about 35 year.

Given that,

Storage capability of computers has been doubling every 5 years

The date of 1st computer made = 1980

computer could store 5 megabytes,

Now,

We can use the following calculation to determine how long it took computers to store 100 megabytes:

Therefore,

Log₂ (final amount / beginning amount)

=  Log₂ (100 / 0.5)

= log₂ (200)

= 7.64 is the number of doublings.

If each doubling takes five years, then it would take computers just over seven doublings or almost 35 years to store 100 megabytes.

Answers

Using the Midpoint Rule, the area of the pool is of 452 m².

What is the Midpoint Rule?

The midpoint is a method of numerical integration to find areas of figures by the sum of areas of rectangles.

The area of a rectangle of length l and width w is given by the multiplication of the measures, as follows:

A = lw.

For this problem, n = 4 means that we should find the areas of 4 rectangles:

From before a1 to a2, with width 10 and length a1 + a2 = 6.2 + 7.2 = 13.4.From after a2 to a4, with width 10 and length a3 + a4 = 6.8 + 5.6 = 12.4.From after a4 to a6, with width 10 and length a5 + a6 = 5 + 4.8 = 9.8.From after a6 to a7, with width 10 and length a6 + a7 = 4.8 + 4.8 = 9.6.

The widths are of 10 because of the division of 5 meter intervals, and each rectangle being composed by two intervals.

The area is:

S = 10 x 13.4 + 10 x 12.4 + 10 x 9.8 + 10 x 9.6 = 452 m².

John has $28 more than Peter. 1/3 of John's money is equal to 4/5 of Peter's money. Find John's money.

Answers

Step-by-step explanation:

Let's start by setting up equations based on the information given in the problem:

Let's say John has x dollars, and Peter has y dollars.

We know that John has $28 more than Peter, so we can write:

x = y + 28

We also know that 1/3 of John's money is equal to 4/5 of Peter's money. In other words:

(1/3)x = (4/5)y

We can simplify this equation by multiplying both sides by 15, which gives:

5x = 12y

Now we have two equations:

x = y + 28

5x = 12y

We can use substitution to solve for x (John's money). We can rearrange the first equation to solve for y:

y = x - 28

Substituting this expression for y into the second equation, we get:

5x = 12(x - 28)

Simplifying this equation, we get:

5x = 12x - 336

7x = 336

x = 48

Therefore, John has $48.

Dilation by a scale factor of 3 with the origin (0, 0) as the center of dilation, followed by a translation of 1 unit up.

Step-by-step explanation:

If two triangles are said to be similar, their corresponding angles are congruent and their corresponding sides are in the same ratio.

Given vertices of triangle ABC:

A = (0, 0)B = (1, 4)C = (5, 2)

To maintain similarity (and thus keep the corresponding angles of both triangles the same) but not maintain congruence, dilate triangle ABC.

Given:

B' = (3, 13)

If ΔABC is dilated by a scale factor of 3, with the origin as the center of dilation, B' = (3, 12).  If the triangle is then translated 1 unit up, B' = (3, 13), which matches the given coordinate of point B'.

Therefore, the series of transformations is:

Dilation by a scale factor of 3 with the origin (0, 0) as the center of dilation.Translation of 1 unit up.

Calculate the circumference of a circle with a radius of 8 inches.

Answers

To calculate the circumference of a circle, you can use the formula:

\(\displaystyle C=2\pi r\)

Where \(\displaystyle C\) represents the circumference and \(\displaystyle r\) represents the radius of the circle.

Given that the radius \(\displaystyle r\) is 8 inches, we can substitute this value into the formula:

\(\displaystyle C=2\pi (8)\)

Simplifying the expression:

\(\displaystyle C=16\pi \)

Thus, the circumference of a circle with a radius of 8 inches is \(\displaystyle 16\pi \) inches.

Note: \(\displaystyle \pi \) represents the mathematical constant pi, which is approximately equal to 3.14159.

4.1.3 Bathu Sneakers have been looking into different shoebox sizes: a large box for male shoes and small box for female shoes. The cost of the cardboard to make the boxes is 0,502 cents/cm². Calculate the percentage savings Bathu Sneakers will make if the smaller box is used compared to the normal larger box. Larger Box Total Surface Area = 4 093 cm² 19 cm 26 cm 34,5 cm Smaller Box Total Surface Area = 3 034 cm² 25 cm 17 cm 26 cm (6)​

Answers

Answer:

Step-by-step explanation:To calculate the savings percentage, we first need to find out the cost of the cardboard required for each box.

For the larger box:

Total Surface Area = 2 * (1926 + 1934.5 + 26*34.5) = 2 * (494 + 655.5 + 897) = 4093 cm²

Cost of cardboard for larger box = 0.502 * 4093 = 2055.986 cents = 20.55986 dollars (rounded to 5 decimal places)

For the smaller box:

Total Surface Area = 2 * (2517 + 2526 + 1726) + 6 * (25-21)* (17-2*1) = 3034 cm²

Note that the additional term in the equation is the surface area of the six sides of the lid and base of the box.

Cost of cardboard for smaller box = 0.502 * 3034 = 1522.268 cents = 15.22268 dollars (rounded to 5 decimal places)

The difference in cost between the larger and smaller boxes is:

20.55986 - 15.22268 = 5.33718 dollars (rounded to 5 decimal places)

The percentage savings can be calculated as follows:

Percentage savings = (difference in cost / cost of larger box) * 100%

= (5.33718 / 20.55986) * 100%

= 25.98%

Therefore, using the smaller box will result in a savings of approximately 26% on cardboard costs for Bathu Sneakers compared to using the normal larger box.

x (x+2) = x+1 + 11

x² + 2x = x + 12

x² + x − 12 = 0

(x + 4) (x − 3) = 0

x = -4 or 3

Since x is positive, x = 3.  So the three integers are 3, 4, and 5.

In the class, Lucy's score is 6.

How to work out Lucy's score?

In statistics, the median is the middle value in a sorted, ascending or descending list of numbers. Thus, it represents the midpoint of the data.

The median is often compared with other descriptive statistics such as the mean (average), mode, and standard deviation.

Since Lucy is one of the 29 students in the class and her score was the same as the median score for her class.

Thus, the median score will be 15th score (i.e. the midpoint of 29). Using the frequency in of each score from the figure, let's keep adding the frequency until we reach 15 and we will then check the corresponding score at the 15th position:

2 + 2 + 4 + 7 = 15

Thus, the the corresponding score at the 15th position is 6.

Therefore, the median score is 6 and consequently Lucy's score is 6.

Answers

On Julie's door, the images will span 210 square inches.

As Julie printed six images, the total space that the images cover is:

6 x 35 square inches = 210 square inches

What is an inch?

Inches are measured as 1/36 of a yard in both British Imperial and American Customary measurement systems. According to some sources, the term "inch" comes from the Old English "ince" or "ynce," which in turn is said to have originated from the Roman "uncia" unit.

The name of another English unit, the ounce, is derived from the Roman word uncia. According to legend, King David I of Scotland defined the old English word "ynce" as the width of a man's thumb at the base of the nail in the year or thereabouts 1150 AD.

From the question:

Six images total, each measuring 5 by 7 inches, were printed by Julie. We must first calculate the area of each image in order to add up the overall area that these photographs cover.

One image's area is as follows:

5 inches x 7 inches = 35 square inches

As Julie printed six images, the total space that the images cover is:

6 x 35 square inches = 210 square inches

Consequently, 210 square inches of Julie's door will be covered by the images.
