Solve For R To Find The Missing Term In Geometric Sequencehi Can Someone Please Answer My Question. Thank

Answers

Answer 1

Step-by-step explanation:

given :

120, 60, 30, _, _, _

find r!

solution :

r = 60/120 = ½.

=> 120,60,30, 15, 15/2 , 15/4 , ...

Answer 2

Step-by-step explanation:

Calcute the ratio :

r = Un/Un-1

r = 60/120

r = ½

Calculate 4th term :

Un = ar^n-1

U4 = 120 × ½^4-1

U4 = 120 × ½³

U4 = 120 × 0.125

U4 = 15

Calculate 5th term :

Un = ar^n-1

U5 = 120 × ½^5-1

U5 = 120 × ½⁴

U5 = 120 × 0.0625

U5 = 7.5

Calculate 6th term :

Un = ar^n-1

U6 = 120 × ½^6-1

U6 = 120 × ½⁵

U6 = 120 × 0.03125

U6 = 3.75

Heather invest $3377 in a retirement account with a fixed annual interest rate of 8% compounded two times per year .how long will it take for the countdowns to reach $14,989.87?
round to the nearest whole year.

Answers

It will take 19 years for the countdowns to reach $ 14,989.87

Given that Heather invest $ 3377 in a retirement account with a fixed annual interest rate of 8% compounded two times per year, to determine how long will it take for the countdowns to reach $ 14,989.87 the following calculation must be performed:

Initial value x (1 + interest rate / compounding times) ^ (years x compounding times) = Compound interest

3377 x (1 + 0.08 / 2) ^ 2X = 14,989.87 3377 x 1.04 ^ 2X = 14,989.87 3512.08 ^ 2X = 14,989.87 X = 19

Therefore, it will take 19 years for the countdowns to reach $ 14,989.87.

Answers

Answer:

x=5

Step-by-step explanation:

Since these angles are vertical angles formed by two parallel lines being intersected by another vertical line, you can set the 18x and 17x+5 equal to each other. Then you solve using algebra. I hope this helps!

Answer:

x=5

Step-by-step explanation:

Because they both equal 90°, you can use the equations, 18x=90 and 17x+5=90 to solve.

First, 18x= 90: (Divide by 18)

x=5

Now, 17x+5=90: (Subtract 5 from both sides)

17x= 85

Then divide by 17:

x= 5

Hope this helps!

Calcula la suma de las longitudes de los catetos, si la hipotenusa mide 15 u y la altura relativa a ella mide 6 u.
UwU

Answers

Answer:

9 sqrt(5)

Step-by-step explanation:

La altura relativa a la hipotenusa corta la hipotenusa en dos segmentos.

Defina x como

x = la longitud de uno de esos segmentos

Entonces, la longitud del otro segmento = 15 - x.

Entonces, por el teorema, tenemos que (15-x) (x) = 36, de modo que

15x - x ^ 2 = 36

x ^ 2 - 15x + 36 = 0

(x-3) (x-12) = 0

Entonces, x = 3 o x = 12.

Sin pérdida de generalidad. sea ​​x = 3.

Entonces, la suma de las dos piernas es

raíz cuadrada (6 ^ 2 + 3 ^ 2) + raíz cuadrada (12 ^ 2 + 6 ^ 2) =

raíz cuadrada (36 + 9) + raíz cuadrada (144 + 36) =

raíz cuadrada (45) + raíz cuadrada (180) =

raíz cuadrada (9 * 5) + raíz cuadrada (36 * 5) =

3 raíz cuadrada (5) + 6 raíz cuadrada (5) =
