Arrange the summation expressions in increasing order of their values

Svetradugi [14.3K]

Sum of n terms = a1 (r^n-1/ (r-1)

Sum of first one = 3 * (4^5 - 1) / 3 = 1023
.. 2nd = 5 * (6^2 - 1) / 5 = 35
.. 3rd = 5 ^4 - 1 / 4 = 156
.. 4th = 4 * (5^4 - 1) / 4 = 624

So in increasing order its 2nd, 3rd, 4th and first.

In a triangle the measure of the first angle is twice the measure of the second angle. the measure of the third angle is 8 degre

Rufina [12.5K]

Let's call the missing angles Q, R, and S. We know that Q = 2R and S = R - 8 and we also know that Q + R + S = 180. So that really just means that 180 = 4R - 8 Add 8 on both sides of the equal sign
188 = 4R So we divide on both sides of the equal sign by 4
47 = R And that means that Q = 2 * 47 So Q = 94 and S = 47 - 8 So S = 39
39 + 94 + 47 = 180
The missing angles are 39 degrees 94 degrees and 47 degrees.

Monthly rent at Lake View Apartments has increased annually and is modeled by the exponential equation y = 2,400(1.04)x. What is

AfilCa [17]

Answer:

The percent increase per year is 4%

Step-by-step explanation:

we have

$y=2,400(1.04^x)$

This is a exponential function of the form

$y=a(b^x)$

where

y represent the monthly rent at Lake View Apartments

x represent the number of years

a is the initial value (y-intercept)

b is the base

r is the rate or percent increase

$b=(1+r)$

The percent increase per year is the base of the exponential function decreased by 1.

so

$r=b-1$

In this problem we have

$a=\$2,400$ ---> initial value

$b=1.04\\r=1.04-1=0.04=4\%$

Therefore

The percent increase per year is 4%
