Convert the recursive equation that is below into an explicit equation where a is the initial value and the time elapsed is 1 ye
aleksley [76]

Answer:

  f(n) = a+200(n -1)

Step-by-step explanation:

The constant difference between terms indicates the sequence is an arithmetic one. The explicit formula for an arithmetic sequence is ...

 an = a1 + d(n -1)

where a1 is the first term and d is the common difference.

Your first term is "a", and your common difference is 200, so the n-th term of the sequence is ...

  an = a + 200(n -1)

Written as a function of n, this is ...

  f(n) = a + 200(n -1)

_____

Based on the problem description, we cannot tell how n relates to time, so we have created an f(n) that gives the same result as the recursive definition of f(n).

Giving a test to a group of students, the grades and gender are summarized below A B C Total Male 10 17 6 33 Female 11 15 13 39
Akimi4 [234]

Answer:

1 / 12

Step-by-step explanation:

Given the following data:

_______A___ B ___C ___Total

Male__ 10 __ 17 ___6___ 33

Female_ 11__ 15___ 13___ 39

Total___21__ 32__ 19___ 72

Find the probability that the student was male AND got a "C"

Number of males who got C = 6

Total number of student students = 72

P(student was male and got C) = (number of males who got C / total number of students)

= 6 / 72

= 1 / 12

Select all of the ratios that are equivalent to 6:16.
kipiarov [429]

Answer : B, D

Step - by - step explanation :

6/16 Divided by 2/2 --> 3/8 ( so it's not 2/8 )

6/16 Multiplied by 2/2 --> 12/32 ( so it's not 12/18 )

30/80 --> 3.75 6/16 --> 3.75

Circle T is shown. Line segment Q S is a diameters. Point R is opposite of point T. Lines are drawn from points Q and S to point
Juliette [100K]

The value of angle x of the given cyclic segment is; 49.5°

<h3>How to find the angle of an arc?</h3>

We are given the measure of the angle of  arc QS as (4x – 18)°

Now, to find the measure of arc QS, this angle is to be equal to 180° and as such;

Thus;

(4x – 18)° = 180°

4x - 18 = 180

4x = 180 + 18

4x = 198

x = 198/4

x = 49.5°

The angle subtended by the arc at the center of a circle with center C is the angle of the arc. It is denoted by. m AB, where A and B are the endpoints of the arc. With the help of the arc length formula, we can find the measure of arc angle.

The formula to measure the length of the arc is;

Arc Length Formula (if angle θ is in degrees); s = 2πr (θ/360°)

Arc Length Formula (if θ is in radians) s = ϴ × r.

Thus, the value of x of the given cyclic segment is; 49.5°
