Answer:

he height of a triangle is 8m less than the base. The area is 10cm^2. Find the height and the base.

I have tried the equation 10=b(b-8)(1/2).

b(b-8) = 20

b^2 - 8b - 20 = 0

Factor:

b^2-10b + 2b-20 = 0

Quoteint of powers
(x^m)/(x^n)=x^(m-n)

we know that 8=x^3

so
(2^5)/8=2^2 can be rewritten as
(2^5)/(2^3)=2^2
and 5-3=2 so it's true

answer is
third one
by simplifieng 8 to 2^3 to make both powers base two, and subtraction the exponents

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 .
