Which sequence can be defined by the recursive formula f (1) = 4, f (n 1) = f (n) – 1.25 for n ≥ 1?

F(1) = 4; f(n+1) = f(n) - 1.25

f(1) = 4

f(2) = f(1) - 1.25 = 4 - 1.25 = 2.75

f(3) = f(2) - 1.25 = 2.75 - 1.25 = 1.50

f(4) = 1.50 - 1.25 = 0.25

f(5) = 0.25 - 1.25 = -1

f(6) = -1 -1.25 = -2.25

Sequence: 4, 2.75, 1.50, 0.25, -1, -2.25, ...

<span> B the smallest piece of cloth that she can make two squares from is one that is two squares wide. So if twice the width of the square is the width of the cloth.The right side of the equation could be clearly written as 2(x^2) to keep it from being confused with (2x)^2.

Tju [1.3M]

Answer:

Step-by-step explanation:

given that an electrical engineer has on hand two boxes of resistors, with five resistors in each box. The resistors in the first box are labeled 10 ohms, but in fact their resistances are 9, 10, 11, 12, and 13 ohms. The resistors in the second box are labeled 20 ohms, but in fact their resistances are 18, 19, 20, 21, and 22 ohms. The EE chooses one resistor from each box and determines the resistance of each

Sample space for selecting one resistor from first box

= {9, 10, 11, 12, 13}

A = {11,12,13} (because >10)

Sample space for selecting one resistor from second box

={18,19,20,21,22}

B={18}

Sample space for sum would be

{27, 28, 29, 30, 31, 32, 33, 34, 35}

C = {(9,19) , (10,18)}

Part A: Find a rational number that is between 7.7 and 7.9. Explain why it is rational. (2 points)

cluponka [151]

Part A.
7.8 is a rational number between 7.7 and 7.9.
It is rational because it can be written as a fraction of integers, such as 78/10.

Part B.
sqrt(60) = 7.75
sqrt(60) cannot be written as a fraction of integers. It is a decimal number that never ends and never repeats.

Two friends went rowing on the river. They first traveled with current for 3 hours. The way back took them 4 hours and 48 minute

kaheart [24]

Answer:

1.5 mph

Step-by-step explanation:

Let speed of boat be x

let speed of current be c

Also, note D = RT

D is distance

R is rate

T is time

Now, for first leg, we can write:

(x+c)3 = D

And for second leg , we can write:

(x-c)4.8 = D [note 4 hour 48 minutes is 4.8 hours]

We can equate both D's to get:

(x+c)3 = (x-c)4.8

3x + 3c = 4.8x - 4.8c

7.8c = 1.8x

We know x = 6.5 [given], plugging it in and solving for c:

7.8c = 1.8(6.5)

c = 1.5

Speed of Current = 1.5 miles per hour
