Find the value of x. If your answer is not an integer, express it in simplest radical form.

DedPeter [7]

Answer:

x = 8√5

Step-by-step explanation:

for right triangle

c^2 = a^2 + b^2

with c is the hypotenuse; a & b are the other sides

(4 + 16)^2 = (4√5)^2 + x^2

400 = 80 + x^2

x^2 = 320

x^2 = 64(5)

√x^2 = √64(√5)

x = 8√5

What is the eighth term in the arithmetic sequence defined by the explicit formula

RideAnS [48]

Answer:

Find out the what is the eighth term in the arithmetic sequence defined by the explicit formula.

$a_{n} = 2n + 7$

To prove

As given the explicit formula for the arithmetic sequence .

$a_{n} = 2n + 7$

Put n = 8

$a_{8} = 2\times 8 + 7$

$a_{8} = 16 + 7$

$a_{8} = 23$

Therefore the eighth term in the arithmetic sequence is 23 .
