The function for the length of a row of bookshelves is [tex]\( f(x) = \frac{4}{5} \sqrt{x} \)[/tex]. graph below.

To find the length of a row of bookshelves, you can use the given relationship that the total length of each row of bookshelves will be [tex]\( \frac{4}{5} \)[/tex] of the length of the storage space. Let's denote the area of the space Isabel rents as [tex]\( x \).[/tex] Then, the length of the side of the square storage space is [tex]\( \sqrt{x} \).[/tex]

So, the length of a row of bookshelves,[tex]\( f(x) \)[/tex], would be:

[tex]\[ f(x) = \frac{4}{5} \times \sqrt{x} \][/tex]

For the function expressing [tex]\( f(x) \)[/tex], it would be:

Lisa owns a large warehouse nearby and can rent space to Isabel. The area of the warehouse is 8,100 square feet. Lisa is willing to rent Isabel as little as 100 square feet of the space or up to as much as the entire warehouse. Her only requirement is that all spaces must be square. The total length of each row of bookshelves will be 4/5 of the length of the storage space.1)

Let x be the area of the space that Isabel rents and f(x) represent the total length of a row of bookshelves. How would you find the length of a row of bookshelves?

The values of x and y are 80 and 70 respectively which make k parallel to j and m parallel to n.

Geometrically, parallel means two or more lines, line segments, or rays that never intersect or cross each other, it doesn't matter how far they are extended. Parallel lines always maintain the same distance between them and remain equidistant at every point.

The sum of two adjacent angles is [tex]180^o[/tex],

therefore,

[tex](x-30)^o+(x+50)^o= 180^o[/tex]

2x +20 = 180

2x = 180 - 20

2x = 160

[tex]\frac{2x}{2} = \frac{160}{2}[/tex]

x = 80.

Again, as the sum of two adjacent angles is [tex]180^o[/tex],

[tex](x-30)^o+y^o= 180^o[/tex]

x + y = 180 + 30

Substitute value of x,

80 + y = 150

y = 150 - 80

y = 70.

Thus, x = 80 and y = 70 are the values for which k is parallel to j and m is parallel to n.

The answer is A or 14.1!

Answer:

The new price of the guitar would be $464.00

Step-by-step explanation:

The original price of the guitar = $320

The music store increased the price of guitar by = 45%

First we calculate 45% of the 320 and then add it to the original price.

The new price of the guitar = 320 + ( 45% × 320 )

                                              = 320 + ( 0.45 × 320 )

                                              = 320 + 144

                                              = $464

The new price of the guitar would be $464.00

Step-by-step explanation:

2) Again, I'm not 100% sure, but I would say 1.05x10^28 because it's the only one with three digits while the other numbers have two digits
3 & 5) The way scientific notation works is that when you have a positive exponent (like 12 and 16) you move the decimal point to the right that amount of times. So for example, take 5.6E12 (E12 is the same thing as saying 5.6x10^12 btw) the exponent would be 12, so you move the decimal point over 12 times. If you want to double check that you have enough zeros, move the decimal point again, and if it ends up at the end of the number when you hit 12, then you're fine. If you hit 12 in the middle of the number, erase all zeros to the right of the decimal point, and if you hit the end too early, add more zeros until you get it right.
4) Now when you have a negative exponent (-10) you do the opposite of 3 & 5 and move the decimal point to the left that amount of times. In this case, you would move the decimal point 10 times to the left, and you can use the same trick as before to make sure you have enough zeros. I also don't know how nitpicky your teacher is, but I would make sure to add one more zero to the left of the decimal just to make sure (by this I mean getting a number like 0.0005 instead of .0005) because some teachers do want you to do that. I hope this explanation helped :)

Given:

Complex number: i − 2?

To add, expressing a number in the form a + bi, whereas the real numbers are b an a, while i is the imaginary unit (which satisfies the equation i2 = −1) is called a complex number. a is called the real part of the complex number, and b is called the imaginary part In the given expression.

The main difference between tangent and chord is that the tangent touches the curve at only one point whereas the chord touches the curve at two points.

Chord:

Tangent:

From above definitions of Chord and Tangent , we say that chord touches the curve at two points where as Tangent touches the curve at only one point .

For more details on chord and tangent follow the link:

A tangent is a line that touches a circle at only one point and is perpendicular to the radius at the point of contact, while a chord is a line segment with both endpoints on the circle.

A tangent and a chord are lines that relate to the curve of a circle, but they have distinct differences. A tangent is a line that touches a circle at exactly one point, and at this point of contact, it is perpendicular to the radius of the circle, which is called the axis in this context. In sharp contrast, a chord is a line segment whose endpoints both lie on the circle. When constructing the perpendicular from the midpoint of a chord, you are drawing an axis. For tangents, the perpendicular erected from the point of contact with the circle is also an axis.

This shows that the tangent is unique in that it has a "no-cut" property; it is the only line that will touch the circle at that single point without cutting through it. When looking at the slope of curves, the slope of the tangent line at the point of contact represents the exact slope of the curve at that point. The differentiation process in mathematics is used to find this slope of the tangent, which is important for understanding the rate of change at a specific point on a curve.

Final answer:

The algebraic expression with a variable 'x' in the numerator and '4' in the denominator translates to the verbal expression 'The quotient of some number and four', indicating a division of 'x' by 4.

Explanation:

The algebraic expression given is a fraction with variable x in the numerator and 4 in the denominator. This expression can be translated into a verbal expression as "The quotient of some number and four". It's important to understand each term used in this expression:

Quotient refers to the result of division.

Some number refers to an unspecified or unknown quantity, which is represented by x in this context.

The number 4 is the divisor in this expression.

Therefore, when we talk about the quotient of some number and four, we are referring to dividing an unknown quantity (x) by four (4).
