Answers

Answer 1
It is 8 because 47-15= 32 & 32/4 =8 (please give me brainliest)
Answer 2

Answer:

8 is the number

Step-by-step explanation:

I don't know why it took me so long to figure it out, 4 x 8 = 32 32 + 15 = 47

It probably took me a really long time because I am tired, and I am not using a calculator.

Step-by-step explanation:

S ∝ t, introduce constant, if value of S depends on t only. Let that constant be 'k'.

=> S = kt

When, S = 0.6 & t = 4:

Answer

=> 0.6 = k(4)

=> 0.6/4 = k

=> 0.15 = k

Therefore, when t = 0.2

=> S = kt

= (0.15)(0.2)

Using the logarithm, solve the following equation for x.
6400 = (8) (2^4x)

Answers

Answer:

x = 2.411

Step-by-step explanation:

6400 = (8) (2^(4x))

Divide both sides by 8 to get;

6400/8 = (2^(4x))

800 = (2^(4x))

Using logarithms, we can solve as;

Log 800 = 4xLog 2

4x = Log800/Log2

4x = 2.9031/0.3010

4x = 9.6449

x = 9.6449/4

x ≈ 2.411

Trigonometric Ratios

The ratios of the sides of a right triangle are called trigonometric ratios.

The longest side of the triangle is called the hypotenuse and the other two sides are the legs.

The sine ratio relates the opposite side of an angle of the triangle with the hypotenuse:

[tex]\displaystyle \sin B=\frac{\text{opposite leg}}{\text{hypotenuse}}[/tex]

Here, the opposite leg to angle B is the side CA=2, and the hypotenuse is the side AB=3, thus:

[tex]\displaystyle \sin \angle B=\frac{2}{3}=0.667[/tex]

Calculating the inverse sine function:

[tex]\angle B=\arcsin (0.667)[/tex]

Answers

Answer:

-1

Step-by-step explanation:

The value of the function when domain y = 30 is f ( 30 ) = -1

What are domain and range?

The domain of a function is the set of values that we are allowed to plug into our function. This set is the x values in a function such as f(x). The range of a function is the set of values that the function assumes. This set is the values that the function shoots out after we plug an x value in.

The range is the set of outputs of a relation or function. In other words, it's the set of possible y values. Recall that ordered pairs are of the form (x,y) so the y coordinate is listed after the x. The output is listed after the input.

Given data ,

Let the function be represented as f ( x )

Now , the value of f ( x ) is

f ( x ) = 14 - ( 0.5 )x   be equation (1)

Now , when the domain of the function x = 30 , we get

f ( 30 ) = 14 - ( 0.5 ) ( 30 )

f ( 30 ) = 14 - 15

On further simplification , we get

f ( 30 ) = -1

Hence , the function is f ( 30 ) = -1

The function rule is the relationship between the input or domain and the output or range. A relation is a function if and only if there exists one value in the range for every domain value.

A function is a relation from a set of inputs to a set of possible outputs where each input is related to exactly one output.

Given data ,

Let the function be represented as A
