Answer:

Step-by-step explanation:

This in standard form (Ax + By = C.) In order to make this slope-intercept form, you need to isolate y.

y = -1.5x + 2.75

y=mx + b is slope intercept, where m is the slope and b is the y-intercept.

In this case, -1.5 is the slope and 2.75 is the y-intercept.

Using trigonometric relations we will see that:

a =  5*√3

b = 5

The correct option is the one you marked.

For a right triangle with a known hypotenuse H and a known angle x, we can use the trigonometric relations:

cos(x)= (adjacent cathetus)/h

sin(x) = (opposite cathetus)/h

Here the hypotenuse measures 10 units, and the known angle is x = 30°.

The adjacent cathetus to that angle is a, so we can write:

cos(30°) = a/10

a = cos(30°)*10  = 10*√3/2 = 5*√3

And b is the opposite cathetus:

sin(30°) = b/10

b = 10*sin(30°) = 5

Then the correct option is the one you marked.

What is factorization and compound interest?

Factorization is the reduction of an algebraic expression into two or more algebraic expressions of smaller degree

If the interest on a certain principal at a certain rate over a certain period of time increases exponentially rather than linearly, the interest earned is called compound interest.

1) a) f(x) = x³+7 x²-36

      f(2) =  2³+7(2)²-36

      f(2) = 36 - 36 = 0

  b) Since f(2) = 0, (x - 2) is a factor of f(x)

      f(x) =  x²(x - 2) + 9x(x - 2) + 18(x - 2)

      f(x) = (x - 2)(x² + 9x + 18)

      f(x) = (x - 2)(x² + 6x + 3x + 18)

      f(x) = (x - 2){x(x + 6) + 3(x + 6)}

Step-by-step explanation:

2x-5>13

2x>13+5

2x>18

x>18/2

x>9

Answer:

x > 9

Step-by-step explanation:

To find the solution to this inequality we need to follow these steps:

2x - 5 > 13

2x > 18 (-5 will be eliminated by +5 on the left side while 13 will be 18 when 5 added to it)

x > 9

It's a right angle as 13² is the addition of 5² and 12².

A right triangle or right-angled triangle, or more formally an orthogonal triangle, formerly known as a rectangled triangle, is a triangle with one right angle, i.e. two perpendicular sides. Trigonometry is founded on the relationship between the sides and other angles of a right triangle.

In this case, the values given are 5, 12 and 13. This will be illustrated thus:

5² + 12² = 13²

25 + 144 = 169

169 = 169

This was done based on Pythagoras theorem.

Therefore, it's a right angle.

Answer:

(23x+4.2)

Step-by-step explanation:

The expression that is a factor of the polynomial x³ + 2x² - 9x - 18 is (x + 2).

Factoring of a polynomial is the method of breaking the polynomial into a product of its factors.

For example x² - 4 can be broken as (x - 2) and (x + 2).

Therefore, the expression that factor the polynomial x³ + 2x² - 9x - 18 is as follows:

Therefore,

x³ + 2x² - 9x - 18 = (x - 3)(x² + 5x + 6)

Let's break (x² + 5x + 6) down

x² + 5x + 6

x² + 2x + 3x + 6

x(x + 2) + 3(x + 2)

(x + 3)(x + 2)

Therefore, the factors are (x + 3)(x + 2) and (x - 3)

Answer:

The answer is C, (x+2).

If P is the minimum number of tests to achieve full statement coverage for f(x) and Q is the minimum number of tests to achieve full branch coverage for f(x), then (P,Q) =(3, 4)

Branch coverage: During program testing, every branch in a statement must be run at least once.

Coverage of the statement:

This means that during testing, every statement in the computer code must be run at least once.

All of the statements must be executed in order to obtain complete statement coverage.

Statement coverage is calculated as (statement executions divided by total statement executions).

To obtain complete statement coverage in the code above, two test cases are necessary.

Case 1: If the if condition is satisfied,

{

int res=0;

if(m<0) {res=n-m;}

return res;

}

These commands will be carried out.

Case 2: All remaining statements will also be put into effect when the other two cases of else do. Full statement coverage is attained after three tests.

Hi,

An angle is coterminal with another angle if it has the same terminal side as the other angle, but may have a different degree measure. In other words, coterminal angles are angles that are measured around the same point on the unit circle, but may start at different points.

To find the angle between 0 and 2π in radians that is coterminal with the angle -25π/6, we can add or subtract multiples of 2π to -25π/6 until we get an angle between 0 and 2π.

For example, adding 2π to -25π/6 gives us:

-25π/6 + 2π = -π/6 + 2π = 7π/6

This angle is between 0 and 2π, so it is coterminal with -25π/6.

Alternatively, subtracting 4π from -25π/6 gives us:

-25π/6 - 4π = -29π/6 = -π/2

This angle is also between 0 and 2π, so it is coterminal with -25π/6.

Therefore, the angle between 0 and 2π in radians that is coterminal with -25π/6 is either 7π/6 or -π/2.

Answer:

The function f(x) = |x - 3| can be used to determine how far a number x is away from the number 3 on the number line. To find the function value for a given x, we first need to subtract 3 from x and then take the absolute value of the result. For example, if x = 5, then the function value would be f(5) = |5 - 3| = |2| = 2.

The domain of the function is the set of all possible values of x that we can plug into the function to get a real number result. In this case, the function will work for any real number value of x, so the domain of the function is the set of all real numbers, which can be written as:

Domain: (-∞, ∞)

In other words, the function f(x) = |x - 3| can be used to determine how far any real number x is away from the number 3 on the number line.

a. Using linear equations in one variable we get the number of songs at which both companies would charge the same amount is 100 songs.

b. Company B would be a better choice as the total charges for 150 songs would be $127.5.

Explain linear equations in one variable.

A straight line with only one variable is a linear equation. the single variable's power is 1. Simple algebraic methods are used to solve these equations, which have the form ax+b=0.

a) Assume the number of songs downloaded is 'x'.

Now according to the question,

Total charges by company A is 15+0.75x

Total charges by company B is 0.90x

For equal charges, both must be equal,

Hence equating the 2 expressions we get,

15+0.75x=0.90x

15=0.15x

x=100

Hence total number of songs to reach the charge of the same amount is 100.

b)Let us take 150 songs from company A, we get the total charge to be

15+0.75*150=$127.5

Taking for company B, we get

0.90*150=$135.

We see that for 150 songs, the charges of company A is less compared to company B. Therefore I would choose company B over company A.

An expression or mathematical expression is a finite arrangement of symbols that are well-formed in line with context-dependent criteria. To help define the logical grammar and order of operations, mathematical symbols can be used to represent variables, operations, functions, brackets, punctuation, and grouping.

A formula and an expression are often distinguished by authors, with the former designating a mathematical entity and the latter a statement about such a thing.

But in contemporary mathematics, and particularly in computer algebra, formulas are seen as expressions that can be evaluated as true or false, depending on the values given to the variables present in the expressions.

Given expression is  [tex](64)^{1/4}[/tex]

The number 64 can be written as 2 × 2 × 2 × 2 × 2× 2 =2⁶
