Answer:

4.6 = x the side opposite C would be 6.1

Step-by-step explanation:

you can use law of sine

you know you have a right triangle so the missing angle B = 49

4/sin41=x/sin49

Let A = {a, b, c, d}, B = {a, c, d, e}. Let f : A → R and g : B → R such that f = {(a, 1),(b, 2),(c, 2),(d, 4)} and g = {(a, 0),(c, 4),(d, 8),(e, 0)}. State the domain and find: f/g​

Answers

Answers:

Domain = {c, d}f/g = { (c, 1/2),  (d,  1/2) }

============================================================

Explanation:

The domain of f:  {a,b,c,d} which is drawn from set A.

The domain of g:  {a,c,d,e} which is drawn from set B

So far, we can see the possible inputs are: a,b,c,d,e

Let's go through each lowercase letter of the given sets

If 'a' is plugged into f/g, then we'll have 0 in the denominator due to the ordered pair (a,0) in function g. This causes a division by zero error so the input 'a' is not allowed in the domain of f/g.If we tried b, then it would work for function f, but it doesn't work for function g. If we tried to compute g(b), then the result is undefined. This is because the lowercase b input is not found in set uppercase B which is where function g selects its inputs from. So b is eliminated.The input c does work however. f(c) = 2 because of the ordered pair (c,2) in the function f. Similarly, g(c) = 4. This means f/g = 2/4 = 1/2 when the input is c. This shows that c is a valid input in the domain of f/g.The input d is pretty much the same story as input c. Moreover, the input d leads to the same output as c does. This time we have f/g = 4/8 = 1/2 when the input is d. Therefore, d is another valid input in the domain of f/g.The input e is not valid because (e,0) will lead to a division by zero error, as it's part of the g(x) function. So we must eliminate 'e' as a valid option in the domain. Even if we didn't have a division by zero error, we still have the fact that 'e' is not in the domain of the first function f. This is another reason why f/g is not defined when the input is 'e'.

To summarize, only inputs c and d are valid in the domain.

The domain is the set {c, d}

Both inputs in the domain lead to the output 1/2. This means the range of f/g is {1/2}. Despite having just one element inside, we must use curly braces to indicate we have a set.

The function f/g is { (c, 1/2),  (d, 1/2) }

We simply list all of the (x,y) ordered pairs to describe the function. In this case, there are only two such pairs.

For what values of k will the equation 4x² + 8x + k = 0 have two complex solutions?

Answers

Answer:

k = -4x² - 8x

Step-by-step explanation:

Subtract 4x²  from both sides of the equation.

8x + k = -4x²

Subtract  8x  from both sides of the equation.

k = -4x² - 8x

Answer:

k > 4

Step-by-step explanation:

Using the discriminant to determine the nature of the solutions

• If b² - 4ac < 0 then the solutions are not real, that is they are complex

Given

4x² + 8x + k = 0

with a = 4, b = 8, c = k , then

8² - (4 × 4 × k) < 0

64 - 16k < 0 ( subtract 64 from both sides )

- 16k < - 64

Divide both sides by - 16, reversing the symbol as a result of dividing by a negative quantity.

k > 4

Any value of k greater than 4 will mean the equation has 2 complex solutions

What is fraction?

A fraction shows part of a whole. This whole can be a region or a collection. The word fraction is derived from the Latin word "fractio" which means 'to break'. The Egyptians, being the earliest civilization to study fractions, used fractions to resolve their mathematical problems, which included the division of food, supplies, and the absence of a bullion currency.

All fractions consist of a numerator and a denominator and they are separated by a horizontal bar known as the fractional bar.

The denominator indicates the number of parts in which the whole has been divided into. It is placed in the lower part of the fraction below the fractional bar.The numerator indicates how many sections of the fraction are represented or selected. It is placed in the upper part of the fraction above the fractional bar.

Given number:

1 3/4 = 7/4

On dividing

7/4 = 1.75

Hence, the number is closer to 2.
