Domain is the set of all values of x of a function. basically just look to see the left and right ends of the function. If it’s a dark circle, put [ or ]. If it’s an open circle, put ( or ). That’s basically how to find the domain. This is an important part of math so make sure you understand this.

Answer:

The length of x is 4

Step-by-step explanation:

The scale factor is Large/small where 10/8 which is DF/AC.

THE SCALE factor is 5/4.

To find the length of X is in AB we use the scale factor 5/4 and the corresponding DE.

5/4 = DE/AB

5/4 = 5/X

X = 4

To find Y in EF will use the corresponding BC which is 6.

5/4 = EF/BC

5/4 = Y/6

Y= 7.5

info: use CORRESPONDING ABC AND DEF .

Write an equation for a polynomial with all the following features a. The degree is 5 b. The polynomial has 4 terms c. The graph

ladessa [460]

Answer:

f(x) = ax^5 + bx^3 + cx^2 + 12.

Step-by-step explanation:

the degree is 5 so we will have a term like:

ax^5

it crosses the vertical axis at y = 12 so we will have a constant term equal to 12

the polynomial has 4 terms, and we already have two so we can make up two more but the exponent must be between 1 and 4

f(x) = ax^5 + bx^3 + cx^2 + 12.

it has 4 terms, f(0) = 12, then it intersects the y-axis at y = 12, and the maximum exponent is 5, then the degree of f(x) is 5

In a music stadium, <em>35th </em>row has <em>120</em> seats

and explicit formula is <em> $a_{n}=3n+15$ </em>is explicit formula for given sequence.

Step-by-step explanation:

In music stadium, there are 18 seats in first row and 21 seats in second row and it is continuously increasing by 3

Here, Arithmetic sequence is 18,21,24,27.....120

There Arithmetic sequence is given as a,a+d,a+d......a+(n-1)d

Where, a = First term = 18 and d = Increment = 3

Q (a) Write an explicit rule to model the sequence formed by the number of seats in each row.

Now, Create an explicit formula

$a_{n}=a+(n-1)d$

$a_{n}=18+(n-1)(3)$

$a_{n}=18+(3n-3)$

<em> $a_{n}=3n+15$ is explicit formula for given sequence.</em>

Q (b) Use the rule to determine which row has 120 seats.

Given $a_{n}=120$

To determine which row has 120 seats.

$a_{n}=3n+15$

$120=3n+15$

$105=3n$

$n=35$

Therefore, 35th row has 120 seats
