Step-by-step explanation:

To obtain a solution for [tex]cos^{-1}[/tex] (x) , then

- 1 ≤ x ≤ 1

That is the value of x cannot be greater than 1 or less than - 1

here x = [tex]\frac{5}{4}[/tex] = 1.25 which is greater than 1 , thus calculator will return ' error'

The graph of the quadratic function [tex]y=ax^2+bx+c[/tex]

does not intersect the x-axis, when [tex]D=b^2-4ac < 0\\[/tex]

touches the x-axis at one point, when [tex]D=b^2-4ac =0[/tex]

intersects x-axis at two points, when [tex]D=b^2-4ac > 0\\[/tex]

For the function[tex]y=4x^2+20x+25[/tex]  the discriminant D is,

This means that the graph of the function touches the x-axis at one point.

[tex]D=20^2-4(4)(25)=200-200=0[/tex]

Since [tex]y=4x^2+20x+25=(2x+5)^2[/tex]then the tangent point has x-coordinate at x=-2.5  (value at which y=0).

Therefore the correct choice is B.

The graph of the function f(x) = 4x² + 20x + 25 passes through the  x-axis at  –2.5.

It is the method to separate the polynomial into parts and the parts will be in multiplication. And the value of the polynomial at this point will be zero.

The function is given as

f(x) = 4x² + 20x + 25

On factorization, we have

f(x) = 0

Then

           4x² + 20x + 25 = 0

   4x² + 10x + 10x + 25 = 0

2x (2x + 5) + 5 (2x + 5) = 0

           (2x + 5)(2x + 5) = 0

                      (2x + 5)² = 0

Then the graph of the function passes through the x-axis at –2.5.

solve for AB:

⇒ AB = AC - BC

⇒ AB = 2x - 7 - ( x - 3 )

⇒ AB = 2x - x - 7 + 3

⇒ AB = x - 4

solve for x:

⇒ x - 4 = 8

⇒ x = 8 + 4

⇒ x = 12

☆solve for AB:

→ AB = AC - BC

→ AB = 2x - 7-(x-3)

→ AB = 2x - x - 7+3

→ AB = x - 4

given, AB = 8

☆solve for x:

→ x - 4 = 8

→ x = 8 + 4

→ x = 12

Answer:

A

Step-by-step explanation:

The margin of error is 3.38.

Option B is the correct answer.

We have,

The margin of error can be calculated using the formula:

Margin of error = z x (s/√n)

where z is the z-score corresponding to the given confidence level.

For a 95% confidence level,

z = 1.96.

Substituting the given values, we get:

Margin of error

= 1.96 x (5.9/√12)

= 3.38

(rounded to two decimal places)

Therefore,

The margin of error is 3.38.

Answer:

Step-by-step explanation:

Step-by-step explanation

first you have 1764 so you need to reduce it so you can keep on going through the line so I divided 1764 by 2 and I got 882. 2 is a prime number so I don't have to worry about it anymore. now I reduce 882 and get 2 and 441. 2 is prime so we don't need to worry about it anymore. now since we can't divide 441 by 2 we will use the next number 3. 441 divided by 3 is 147. 3 is prime so we don't need to worry about it anymore. 147 can't be divided by 2 so we will try 3 again and that works so 147 divided by 3 is 49. 3 is prime so we don't have to worry about it anymore. now we have 49 and 49 is a normal multiplication fact so we know that 49 divided by 7 is 7. and seven is prime so now you have have all the prime factors of 1764

sqrt*1300=36.05551275464

Answer:

hypotenuse: 36.06 feet

using Pythagoras theorem:

a² + b² = c²

30² + 20² = c²

c² = 900 + 400

c² = 1300

c = √1300

c = 36.0555 feet

Polynomials are represented by graphs and equations

The equation of the polynomial is y = x^3 + 12x^2 + 29x - 42

From the graph, the zeros of the polynomial are:

x = {-7, -6, 1}

So, the equation of the polynomial is:

[tex]y = (x + 7) * (x + 6) * (x - 1)[/tex]

Expand

[tex]y = (x^2 + 13x + 42) * (x - 1)[/tex]

Further, expand

[tex]y = x^3 + 13x^2 - x^2 + 42x - 13x - 42[/tex]

This gives

[tex]y = x^3 + 12x^2 + 29x - 42[/tex]

Hence, the equation of the polynomial is y = x^3 + 12x^2 + 29x - 42

Answer:

I don't understand this question...

Step-by-step explanation:

But If you want a fraction greater than 100% than you have to find a percentage that is greater than 100% and convert it into a fraction

Answer: In a fraction, when the numerator is smaller than the denominator, the percent is either between 1% and 100 % or less than 1 %. To make sure that the given fraction is less than 1%, better convert the given fraction into decimal and then convert into percent. In decimal, when the given value is greater than 1, the percent is greater than 100%.

Step-by-step explanation: (1) Divide number by the other number, then (2) multiply by 100 to convert the result to a %. (3) If both numbers are positive, and the resulting percentage is greater than 100%, the numerator is larger than the denominator.
