Answer:

a(7)=3645

Step-by-step explanation:

you have :

f(1) =a= 5

and from recursive rule: f(n) = r · f(n − 1) and f(n) = 3 · f(n − 1)

So r=3

then

a(n)=a*r^(n-1)

a(7)=5*3^(7-1)

a(7)=5*3^6=3645

hope this helps

What is the slope of (3,5) and (1,3)

Maksim231197 [3]

(3,5)....x1 = 3 and y1 = 5
(1,3)....x2 = 1 and y2 = 3

slope formula : (y2 - y1) / (x2 - x1)
slope = (3 - 5) / (1 - 3) = -2/-2 = 1 <== slope is 1

Bart wants to deposit his piggy bank savings into a savings account. If he deposits $325. 76, how many whole years will it take,

vladimir1956 [14]

Answer:

Step-by-step explanation:

Compounding interest :

Future value of money = Present value * (1+ r)^N

r - interest rate

n - number of period

In our example, Present value = 325.76, FV = 400, r = 2%, and we need to find N

by solving that we can find it that N is equal to 10.3675

Simple interest :

400 - 325.76 = 74.26$ we need to increase

325.76*2% = 6.5152$ each year

74.26 / 6.5152 = 11.3949

as a whole year = 12years

A central angle of a circle measures 42 degrees. What else can be shown to measure 42 degrees?

Slav-nsk [51]

Answer:

Vertically opposite angles

Step-by-step explanation:

Given

$\theta = 42^\circ$

Required

What else can measure $\theta = 42^\circ$

The question has missing options. So, I will give a general explanation.

Using the attached image as a point of reference.

Given that:

$\theta = 42^\circ$

The value of b is calculated as:

$b = \theta$

Because b and $\theta$ are vertically opposite angles

This gives:

$b = 42^\circ$

So, one possible answer to the question is a vertically opposite angle
