Find the 10th term of the arithmetic sequence with the terms a1=15 and d=80

Alchen [17]

Answer:

The 10th term is 735

Step-by-step explanation:

The 10th term of an <em>Arithmetic Sequence </em>is given by:

$a_{10}=a_1+9d$

From the question, we were given that:

$a_{1}=15$

and

$d = 80$

We substitute these values into the above expresion to obtain:

$a_{10}=15+9 \times 80$

$a_{10}=15+720$

$a_{10} = 735$

Solve for x. Answer in Interval Notation using Grouping Symbols.<br> x^2+9x<-20

AURORKA [14]

Answer:

In interval notation:

(-5,-4)

Step-by-step explanation:

To solve the expression shown in the problem you must:

- Add 20 to both sides, then:

$x^{2}+9x+20$

- Now you must find two number whose sum is 9 and whose produt is 20. These would be 4 and 5. Then, you have:

$(x+4)(x+5)$

- Therefore the result is:

$-5$

In interval notation:

(-5,-4)
