Show that the function f(x)= integral from x to 3x 1/t ft is constant on the interval (0, positive infinity)
jarptica [38.1K]
\int\limits^{3x}_x { \frac{1}{t} } \, dt
integrate to get
[ln|t|]^{3x}_x=ln|3x|-ln|x|=ln| \frac{3x}{x}| =ln |3|=ln(3)
this only is true when x>0
when x turns negative, we get -ln(3) because of math

Consider the linear equation, 2.5n + 5.2 = 35.2.
OverLord2011 [107]

Answer:

Subtraction Property of Equality

Step-by-step explanation:

When solving an equation for a variable (in this case n), we want to move all of the n-terms to 1 side and the non-n terms to the other side. To do this, we can subtract 5.2 from both sides to leave 2.5n by itself. The property we used to do this is the Subtraction Property of Equality which states that if you subtract a quantity from one side of an equation, you must also subtract that same quantity from the other side of the equation.

NEED HELP FAST WILL GIVE BRAINLIEST
Brrunno [24]

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
