Answer: $\bold{(A)\ a_n=500,000(1.1)^{n-1}}$

<u>Step-by-step explanation:</u>

From the data provided, we know the sequence is {500,000; 550,000; 605,000; ... }. $So, a_1 = 500,000\ and\ r = \dfrac{550,000}{500,000}=1.1$

The explicit rule for a geometric sequence is: $a_n=a_1(r)^{n-1}$

So, the explicit rule for the sequence above is: $a_n=500,000(1.1)^{n-1}$

weeeeeb [17]

Answer: 106

Step-by-step explanation: you have a total of 180 degrees in there, so you only gotta find the unknown value of the other side so you do 180 - 64 which is 116. then you see that in order to get 116 you gotta add it times ten which you are gonna subtract by 10 which is 106, and 106 will be your answer.

PLEASE HURRY

Fynjy0 [20]

Answer:

t=18 years

Step-by-step explanation:

A year has two semesters, then

n = 2v(t)=p(1+r/2)2t

3875.79 = 1900∗(1+(0.04/2))^2t

2.0398895 = (1+0.042)^2t

Apply natural logarithm on both sides

ln(2.0398895) = ln[(1+0.042)^2t]

Then simplify,

0.712896 = 2t∗ln(1.02)

t = 0.712896 / (2∗ln(1.02))

t=18 years

Answer:

Step-by-step explanation:

$\text{x-intercept is for y = 0}.\\\\\text{We have the function:}\ y=x^2-7x+12.\\\\\text{Put y = 0 and calculate the value(s) of x.}\\\\x^2-7x+12=0\\\\x^2-3x-4x+12=0\\\\x(x-3)-4(x-3)=0\\\\(x-3)(x-4)=0\iff x-3=0\ \vee\ x-4=0\\\\x-3=0\qquad\text{add 3 to both sides}\\\boxed{x=3}\\\\x-4=0\qquad\text{add 4 to both sides}\\\boxed{x=4}$

Find the zeros of the polynomial function: <br> f(x) = 9x^3 - 27x^2 - 4x + 12.

hichkok12 [17]

Answer:

{-2/3, 2/3, 3}

Step-by-step explanation:

The equation can be factored by grouping.

f(x) = (9x^3 -27x^2) +(-4x +12)

f(x) = 9x^2(x -3) -4(x -3)

f(x) = (9x^2 -4)(x -3)

We recognize the first factor as the difference of squares, so know it can be further factored to give ...

f(x) = (3x -2)(3x +2)(x -3)

The zeros are the values of x that make these factors be zero:

3x -2 = 0 ⇒ x = 2/3

3x +2 = 0 ⇒ x = -2/3

x -3 = 0 ⇒ x = 3

The zeros of the polynomial are x = -2/3, 2/3, 3.
