Please answer these with lots of detail. I want to be able to understand the topic and material well.

Answers

Answer 1

Step-by-step explanation:

(a) If 0 < |x − 1| < δ, then |f(x) − 2| < 2

What this means is, how far can x stray from the x=1 line such that f(x) stays within 2 units of the y=2 line (0 < f(x) < 4).

If we move 2 units left of x=1, we get f(x) = 4.

If we move about 3.5 units right of x=1, we get f(x) = 4.

Therefore, δ can't be more than 2.

(b) If 0 < |x| < δ, then |f(x) − 3| < 1

What this means is, how far can x stray from the x=0 line such that f(x) stays within 1 unit of the y=3 line (2 < f(x) < 4).

If we move 1 unit left of x=0, we get f(x) = 4.

If we move 1 unts right of x=0, we get f(x) = 2.

Therefore, δ can't be more than 1.

Since f(x) isn't continuous within this domain, we can't conclude that the limit exists.

(a) Yes. If δ = 0.25, then 0.75 < x < 1.25, and f(x) > 200.

(b) No. f(1) = 300, so even if δ = 0, f(x) will be less than 400.

Step-by-step explanation:

Question (9)

Let a number = x

45% increase in the given number will be = x + (45% of x)

= x + [tex]\frac{45x}{100}[/tex]

= x + 0.45x

= x(1 + 0.45)

= 1.45x

Therefore, there will be the two expressions,

A). 1.45x

B). x + 0.45x

Options (A) and (B) will be the correct options.

Factor the polynomial expression x4 + 18x2 + 81 to determine missing terms

X^4+18x^2+81=( )^2+2( )x^2+ ( )^4

Answers

Answer:

Step-by-step explanation:

Explanation:

Use the extended form of the perfect square trinomial identity:

a4 + 2a2b2 + b4 = (a2 + b2)2.

a2 = x2 and b2 = 32

x4 + 18x2 + 81 = (x2)2 + (2)(x2)(32) + (32)2

= (x2)2 + 2(32)x2 + (32)2

= (x2 + 32)2

= (x2 + 9)2

The missing terms are (x²)² + 2(9)x² + (3²)² and (x² + 9)² after factorization of the polynomial.

What is polynomial?

Polynomial is the combination of variables and constants systematically with "n" number of power in ascending or descending order.

[tex]\rm a_1x+a_2x^2+a_3x^3+a_4x^4..........a_nx^n[/tex]

We have a polynomial:

= x⁴ + 18x² + 81

Let u = x²

[tex]\rm =u^2+18u+81[/tex]

= (x²)² + 2(9)x² + (3²)²

= (u + 9)²

= (x² + 9)² or

= (x² + 9)(x² + 9)

Thus, the missing terms are (x²)² + 2(9)x² + (3²)² and (x² + 9)² after factorization of the polynomial.

What is a rectangular prism?

It is defined as the six-faced shape, a type of hexahedron in geometry.

It is a three-dimensional shape. It is also called a cuboid.

It is given that:

Two rectangular box are shown in the picture.

The volume of the rectangular box = length×width×height

The total volume of the two boxes = (x+3)(x+5)3x + 2x(3x+9)(4x-8)

After simplification:

= 3x³ + 24x² + 45x + 24x³ + 24x² - 144x

= 27x³ + 48x² - 99x

Thus, the total volume of the two boxes is 27x³ + 48x² - 99x option (C) 27x³ + 48x² - 99x is correct.
