What is 5(4x+3)= simplified​

Mathematics
2 answers:
Natali [406]2 years ago
5 0

Answer:

The simplified answer is 20x + 15

Step-by-step explanation:

The first and only step we have to do here is distributive property.

Distributive property means to multiply the number outside the parentheses to all of the numbers inside the parentheses.

Such as 5 × 4x and 5 × 3

Then we keep the sign that was in the parentheses and plug in your answers

so 20x + 15

if you have any questions feel free to ask in the comments.

5(4x+3)=0

20x+15=0

20x = -15

x =  \frac{ - 15}{20}

x =  \frac{ - 3}{4}

Identify the domain and range for the table from problem #5 of your assignment. Also, determine if it represents a function.
Lana71 [14]

Answer:

Domain: {4,5,7,10}

Range: {2,4,8}

Not a function

Step-by-step explanation:

The domain is all the x-values.

The range is all the y-values.

However, this isn't a function because two different inputs have the same output. If it were a function, there would be one unique output for every input.

The graph of the function showing the path of a soccer ball thrown by a goalie in a video game, f(x) = –0.05x2 + 2.5x + 5.2, is
Tju [1.3M]

Answer:

The correct option is 4.

Step-by-step explanation:

The given function is

f(x)=-0.05x^2+2.5x+5.2

Where f(x) is height of the ball and x is the distance.

It is a polynomial function with degree 2. All polynomial functions are defined for all real numbers, therefore the mathematical domain of the function is all real numbers.

-\infty

Factorize the given function.

f(x)=-0.05(x^2-50x-104)

f(x)=-0.05(x^2-50x-104)

f(x)=-0.05(x^2-52x+2x-104)

f(x)=-0.05(x(x-52)+2(x-52))

f(x) = -0.05 (x - 52) (x + 2)

Put f(x)=0 to find the x intercepts.

0 = -0.05 (x - 52) (x + 2)

Equate each factor equal to 0.

x=52,-2

Therefore at x=52 and -2, the graph of f(x) intersects x-axis. Before x=-2 and after x=52 the values of f(x) is negative. Height cannot be negative, therefore reasonable domain is lie between -2 to 52.

Distance cannot be negative, therefore the reasonable domain must be positive.

0\leq x\leq 52

Therefore the reasonable domain is 0\leq x\leq 52 and option 4 is correct.
