What is the value of a1 of the geometric series? Sigma-Summation Underscript n = 1 Overscript infinity EndScripts 12 (negative o

worty [1.4K]

Answer:

Step-by-step explanation:

The given geometric series is

$\sum_{n = 1}^{ \infty} 12( { - \frac{1}{9} })^{n - 1}$

We want to determine the first term of this geometric series.

Recall that the explicit formula is

$a_{n} = 12( { - \frac{1}{9} })^{n - 1}$

To find the first term, we put n=1 to get:

$a_{1} = 12( { - \frac{1}{9} })^{1 - 1}$

This gives us:

$a_{1} = 12( { - \frac{1}{9} })^{0}$

$a_{1} = 12(1) = 12$

Therefore the first term is 12

Sedaia [141]

Answer:

The senior class will have 100 members in the 13th year.

Step-by-step explanation:

Use the compound interest equation with a negative interest rate:

A = P(1 + r/n)^(n)(t)

Let n be 1 since we're looking for a specific year.

100 = 250(1 - 0.07)^t

100/250 = (0.93)^t

0.4 = (0.93)^t

t = 13 years

Value of X. Please give step by step so I understand

otez555 [7]

Answer:

The value of x is 15.

Step-by-step explanation:

Since the base is 40 inches long, and the two triangles are congruent - both are right triangles and have sides x and their bases equal - you know that each base of a triangle is 20 inches long. Using the Pythagorean Theorem, you can get that $x^2+20^2=25^2$ . Solve for x by isolating the variable on one side: $x^{2} =25^{2} - 20^{2}$ ⇒ $x^{2} = 625 - 400$ ⇒ $x^{2} = 225$ ⇒ $x^{2} =225$ ⇒ $x=\sqrt{225}$ ⇒ $x=15$ inches.
