Find the formula for the nth term of the sequence: 0,7,18,33,52​

Answers

Answer:

t(n) = 2n² + n - 3

Step-by-step explanation:

Given sequence:

0, 7, 18, 33, 52

Find the formula for nth term t(n)

Solution

Sequence is neither arithmetic nor geometric, analyzing:

0, 7, 18, 33, 52

First level difference

7, 11, 15, 19

Second level difference

4, 4, 4

As there are two levels, the formula should be in the form of:

t(n) = an² + bn + c

Trying the formula with the known terms:

t(1) = 0 ⇒ a+b + c= 0t(2) = 4a + 2b + c = 7 ⇒ 3a + b = 7t(3) = 9a + 3b + c = 18 ⇒ 3(3a+b) + c = 18 ⇒ 21 + c = 18 ⇒ c = -3

Going back to previous equations to find remaining coefficients:

t(1) ⇒ a+ b = 3 ⇒ t(2) = 2a + (a+b) = 7 ⇒2a + 3 = 7 ⇒ a= 2 ⇒ b = 1

So the formula becomes:

t(n) = 2n² + n - 3

The definition of a triangle is a polynomial with 3 sides and interior angles adding up to 180.

Using the definition, we can create an equation.

[tex]180=42+31+x[/tex]

[tex]180=73+x[/tex]

[tex]x=107[/tex]

The measure of the third interior angle is 107 degrees.

Hope this helps.

頑張って!

Answer:

107

Step-by-step explanation:

triangle angles = 180

31 + 42 = 73

180 - 73 = 107

(f - g)(x) = (3x - 1) - (x +2)
Solve.

Answers

Answer:

Step-by-step explanation:

If you want the difference between functions f and g, combine the terms within parentheses as follows:

(f - g)(x) = (3x - 1) - (x +2)

             = 3x - 1 - x - 2

Evelyn has $524.96 in her checking account. She must maintain a $500 balance to avoid a fee. She wrote a check for $32.50 today. Write an inequality that would be used to solve for the least amount of money she needs to deposit to avoid a fee. 524.96 − 32.50 + x ≥ 500 524.96 − 32.50 + x ≤ 500 524.96 + 32.50 − x ≥ 500 524.96 + 32.50 − x ≤ 500

Answers

Answer:

524.96 − 32.50 + x ≥ 500

Amount need to deposit = $7.54

Step-by-step explanation:

Given:

Amount in checking account = $524.96

Maintain amount = $500

Amount of check = $32.50

Find:

Amount need to deposit

Computation:

Assume, amount need to deposit = x

So,

For avoiding fee

524.96 − 32.50 + x ≥ 500

x = 7.54

Amount need to deposit = $7.54

A quadrilateral has angle measures of 41 52 and 54 which is the measure of the last angle

Answers

Answer:

213 degrees

Step-by-step explanation:

A quadrilateral has an internal measurement of angles of 360 degrees.  Given that we have 3 measures of the angles, we simply need to find the 4th.  This can be accomplished with the following equation:

x + 52 + 54 + 41 = 360

x + 52 + 95 = 360

x + 147 = 360

x = 213

Hence, the measure of the final angle is 213 degrees.

x+6/4 + x-3/5 = 5x-4/8​

Answers

Answer:

x = 7/15

Step-by-step explanation:

x + 6/4 + x - 3/5 = 5x - 4/8

x + x - 5x = -4/8 - 6/4 + 3/5

-3x = -2/4 - 6/4 + 3/5

-3x = -8/4 + 3/5

-3x = -2 + 3/5

-3x = -10/5 + 3/5

-3x = -7/5

x = (-7/5)/-3

x = -7/(5*-3)

x = -7/-15

x = 7/15

Check:

7/15 + 6/4 + 7/15 - 3/5 = 5(7/15) - 4/8

14/15  + 6/4  - 3/5 = 35/15 - 2/4

56/60 + 90/60 - 36/60 = 140/60 - 30/60

146/60 - 36/60 = 110/60

An actor gains 20 pounds for a part and then loses 15 pounds during the filming of the movie to go along with the story. How many pounds is the actor above or below his original weight?

Answers

Answer:

5 pounds above his original weight

Step-by-step explanation:

An actor gains 20 pounds for a role in a movie

He loses 15 pounds during the movie to blend with the story line of the movie

Since he gained 20 pounds and loses 15 pounds

20 pounds -15 pounds

= 5 pounds

Hence the actor is 5 pounds above his original weight
