What is the value of the fourth term in the geometric sequence

ivanzaharov [21]

Answer:

a(4) = 15/4

Step-by-step explanation:

Here we're told that the first term is a(1) = 30 and that the common factor r = 1/2.

Thus, the geometric sequence formula specific to this case is

a(n) = 30(1/:2)^(n-1).

What is the fourth term? Let n = 4,

a(4) = 30(1/2)^(4-1), or a(4) = 30(1/2)^(3), or a(4) = 30(1/8) = 30/8, or, in reduced form,

a(4) = 15/4.

A triangle has a side lengths of 3 and 8. The diagonal has a length of 11. Can this be a right triangle? Show your work to prove

If the triangle is a right triangle, the pythagorean theorem would work
since it doesn’t, the triangle is NOT A RIGHT TRIANGLE

Solve for x please describe the steps 50 points

LuckyWell [14K]

Answer:

x = 6

explanation:

USE: $\boxed{\frac{side-length }{base -length} = \frac{side-length}{base -length} }$

solve:

$\frac{21}{15} = \frac{7}{x-1}$

$21(x-1) = 7(15)$

$21x-21 = 105$

$21x = 105+21$

$21x = 126$

$x = \frac{126}{21}$

$x = 6$
