The nth term of the sequence is n^2 + 20
How many terms in the sequence are less than 50

Answers

Answer:

5 terms

Step-by-step explanation:

nth term of the sequence =n^2 + 20

an= n^2 + 20

1st term when n= 1

1^2 + 20= 20

2nd term n= 2

2^2 + 20=24

3rd term when n= 3

3^2 + 20= 29

4th term when n= 4

4^2 + 20= 36

5th term when n= 5

5^2 + 20 =45

6th term when n= 6

6^2 + 20=56

Hence, terms in the sequence are less than 50 are first 5 terms

Given the function below, evaluate h(c) for c = 5
h(c) = 6c² - 76 - 2

Answers

Answer:

72

Step-by-step explanation:

Substitute c = 5 into h(c) , that is

h(5) = 6(5)² - 76 - 2 = 6(25) - 78 = 150 - 78 = 72

Plug in five to the equation, for example: h(5)=6(5) squared -76-2 5 squared is 25 6x25=150 ... 150-76-2=72.... h(5)=72 divid both sides by 5 to find the value of “h” (h=14.4)

4) True

Image 2: -4

Step-by-step explanation:

y = 50x + 40

y = 60x + 20

y = 50(6) + 40 = 340

y = 60(6) + 20 = 380

140 = 50x + 40

50x = 100

x = 2

140 = 60x + 20

60x = 120

x = 2

) Your father uses text messaging to communicate with his employees. If he sends an average of 19 text messages each day, how many more text messages does he send than you? Write an equation and solve for the unknown value. (2 points)

Answers

Answer:

father sends 7 more

Step-by-step explanation:

19-12=7

The equation representing the situation is x = 19 - 12 and the value of x is 7.

What is an Equation?

An equation is the statement of two expressions located on two sides connected with an equal to sign. The two sides of an equation is usually called as left hand side and right hand side.

Given that,

Number of text messages that your father sends a day = 19

Number of text messages that you sends a day = 12

The equation that represents how many more text messages father sends than you is,

x = 19 - 12

where, x represents the number of text messages that your father sends more.

Solving this, we get,

x = 7

Hence father send 7 more messages than you.

Answer:

[tex]y = \frac{-3}{4}[/tex]

Step-by-step explanation:

[tex]\frac{y}{2} + \frac{1}{4} = \frac{y}{6}[/tex]

Lets take all the variable terms in L.H.S & all the constant terms in R.H.S.

(While taking a term from one side to another side , it's sign changes )

⇒ [tex]\frac{y}{2} - \frac{y}{6} = -\frac{1}{4}[/tex]

Now in L.H.S. , lets solve the fractions and reduce its numerator and denominator .

⇒  [tex]\frac{3y - y}{6} = -\frac{1}{4}[/tex]

⇒  [tex]\frac{2y}{6} = -\frac{1}{4}[/tex]

⇒  [tex]\frac{y}{3} = -\frac{1}{4}[/tex]

Lets multiplying 3 on both the sides .

⇒  [tex]\frac{y}{3} \times 3 = -\frac{1}{4} \times 3[/tex]

⇒  [tex]y = \frac{-3}{4}[/tex]
