The distance first from bottom of both the pole to the anchor point is approximately 56 feet smaller than the height of the pole, hence 44 feet cannot be the height of the pole. the height of both pole is 496 feet.

In mathematics, a quadratic equation is a second-degree equation of both the form ax2 + bx + c = 0. The coefficients are a and b, the constant term is c, and the variable is x. Because the variable x has a second degree, this quadratic equation has two roots or answers.

A telephone pole is said to have a cable attached to its top that is secured to the ground. The distance from the pole's bottom to the anchor point is 56 feet less than the pole's height. So the distance from the bottom of the pole to the anchor point is:

x - 56

The wire must be 8 feet longer than just the height of the pole, thus the wire length would be:

x + 8

We know that the length of the wire is the hypotenuse of a right triangle, thus we can apply Pythagoras' theorem as follows:

(x + 8)²  = x² + (x - 56)²

x² + 16x +64 = x² +  x² - 112x + 3136

x² + 16x +64 = 2x²  - 112x + 3136

2x² + 32x + 128 = x² - 56x + 1568

2x² + 32x + 128 - x² + 56x - 1568 = 0

x² - 88x + 1440 = 0

The value pf x will be:

x = 44

x = 496

The distance first from bottom of both the pole to the anchor point is approximately 56 feet smaller than the height of the pole, hence 44 feet cannot be the height of the pole. the height of both pole is 496 feet.

The explicit formula of the sequence is Tn = 30 - 20(n - 1)

The recursive formula of the sequence is given as

f(1) = 30, f(n) = 2 • f(n - 1) - 50

The above means that

f(n) = 2 • f(n - 1) - 50

f(1) = 30

Substitute 2 for n

So, we have

f(2) = 2 • f(2 - 1) - 50

Evaluate the difference

So, we have

f(2) = 2 • f(1) - 50

Substitute f(1) = 30 in f(2) = 2 • f(1) - 50

f(2) = 2 • 30 - 50

Evaluate

f(2) = 10

Substitute 3 for n

So, we have

f(3) = 2 • f(3 - 1) - 50

Evaluate the difference

So, we have

f(3) = 2 • f(2) - 50

Substitute f(2) = 10 in f(3) = 2 • f(2) - 50

f(3) = 2 • 10 - 50

Evaluate

f(3) = -30

So, we have the first three terms to be

30, 10, -10

The above represents an arithmetic sequence, where

First term, a = 30

Common difference = -20

The nth term of the sequence is

Tn = a + (n - 1)d

So, we have

Tn = 30 - 20(n - 1)

Hence, the explicit formula of the sequence is Tn = 30 - 20(n - 1)

Solve the inequality |x−2|≥9

Inequality is a Mathematical statement that shows the relation between two expressions using the inequality symbol. The expressions on both sides of an inequality sign are not equal. It means that the expression on the left-hand side should be greater than or less than the expression on the right-hand side or vice versa.

a) |x−2|≥9 = x-2≥ 9

Hence proved, x*0 = 0.

A statement that is assumed to be true is referred to as a postulate, axiom, or assumption. It is used as the foundation for further deductive reasoning and arguments.

Given many of the typical formulations of the Peano axioms, for example, this is the base case for the definition of multiplication, so it’s an axiom, not a theorem.

x*o = 0

By using an example as rings:

Therefore, By definition of negotiation

0 = x · 1 + ( - x) where 1 is the multiplicative identity,

Now,

= x · ( 0 + 1) + ( - x)

Therefore by distributive law,

= x · 0 + x · 1 + (-x)

Where 1 is the multiplicative identity.

By definition of negotiation,

If the width of the painting is w, then its length is 2w. Then, since the frame is 2 inches thick on each side of the painting, its width is w+4 and its length is 2w+4. So the area of the rectangle bounded by the frame (which includes both the area of the frame and the area of the painting) is (w+4)(2w+4).

The area of the painting is w×2w=2w2, and the area of the frame is 196 square inches, so the area of the two combined is 2w2+196. However, that is the same area as the other one I described, so we can then equate the two, i.e. (w+4)(2w+4)=2w2+196. You can then solve that equation for w, and hence find all of the relevant dimensions.

Now, we want to solve for  (f + g) (x). From operations of functions, we know that there are different operations which could  include addition, division, multiplication and subtraction. However, in this case;

(f + g) (x) simply means;

(f + g) (x) = f(x) + g(x)

A limit is given by the value of function f(x) as x tends to a value. For a standard function, we just calculate the numeric value of a function.

However, in this problem, an horizontal limit means that x goes to infinity, hence it we replace and calculate the numeric values we would have a fraction of infinity divided by infinity as a result, which is an undetermined limit.

Then, we use the algorithm to solve an infinity limit, in which we consider just the term with the highest exponent of both the numerator and of the denominator.

Step-by-step explanation

The sum of the three lengths is 9 + 12 +x =  21 + x

We know the sum ranges from 31 to 40

So we get the inequality

31 ≤ 21 + x ≤  40

Subtracting 21 from each part of this inequality give

31-21 ≤ x ≤40-21

10 ≤ x ≤ 19

The compound inequality to show the possible lengths of the third side is 10 ≤ x ≤ 19.

A statement of an order relationship-greater than, greater than or equal to, less than, less than or equal to- between two numbers or algebraic equations.

Now it is given as,

Range of sum of three lengths of a fence = 31 to 40 inches

Length of two sides = 9 and 12 inches

Length of third sides = x inches

So, length of sum of three lengths of a fence = 9 + 12 + x

⇒  length of sum of three lengths of a fence = 21 + x

∵ Range of sum of three lengths of a fence = 31 to 40 inches

31 ≤ length of sum of three lengths of a fence ≤ 40

⇒ 31 ≤ 21 + x ≤ 40

Subtracting 21 we get.

10 ≤ x ≤ 19

Thus, the compound inequality to show the possible lengths of the third side is 10 ≤ x ≤ 19.
