A sequence is defined by the recursive formula f (n + 1) = f(n) – 2. If f(1) = 18, what is f(5)?
Step-by-step explanation:
f(2)=18-2=16
f(3)=16-2=14
f(4)=14-2=12
Then,
f(5)=12-2=10
the answer is 10

Answer:
Frequency = 8 Hz ; Period = 0.125 s
Step-by-step explanation:
The amplitude of a wave is simply regarded as the maximum displacement experienced by a vibrating both from its equlibrum position.
The Displacement marked A in th picture is tbe Amplitude of the wave
The wavelength refers to the a complete cycle moved by a wave, that is the distance from a crest to another (maximum upward Displacement) or a trough to another (maximum downward Displacement).
2.)
Given that :
Velocity (V) of wave = 20 m/s
Wavelength (λ) = 2.5 m
The frequency (f) of the wave ;
f = v /λ
f = (20 m/s) ÷ 2.5m
f = 8 Hz
The period T of the wave :
T = 1 /f
T = 1 / 8
T = 0.125 seconds
Find the value of x so that the function has the given value.
n(x) = -6x + 2; n(x) = 44
9514 1404 393
Answer:
x = -7
Step-by-step explanation:
Substitute the given value and solve for x
n(x) = -6x +2
44 = -6x + 2
42 = -6x . . . . . subtract 2
-7 = x . . . . . . . divide by -7
n(x) will have the value 44 for x = -7.
A firm has a cash conversion cycle of 80 days, an average collection period of 25 days, and an average age of inventory of 70 days. Its operating cycle is ________ days.
Answer: 95 days
Step-by-step explanation:
Cash conversion cycle = 80 days
Average collection period = 25 days
Average age of inventory = 70 days
Then, operating cycle will be:
= Average collection period + Average age of inventory
= 25 days + 70 days
= 95 days

find the determinant of the following matrix. [2 3] [1. 4]
Answer:
5
Step-by-step explanation:
[2 3]
[1 4]
The determinant of the above matrix can be obtained as follow :
|2 3|
|1 4|
= (2×4) – (1×3)
= 8 – 3
= 5
Thus, the determinant of the metrix is 5
You want to buy a shirt that costs $14. Identify an inequality that represents the amount of money, x (in dollars), you will have left if you buy the shirt
Complete question :
You can spend up to $35 on a shopping trip.
a. You want to buy a shirt that costs $14. Write and solve an inequality that represents the amount of money you will have left if you buy the shirt.
b. You notice that the shirt is on sale for %30 off. How does this change the inequality?
c. Do you have enough money to buy the shirt that is on sale and a pair of pants that cost $23? Explain.
Answer:
x ≤ 21
x ≤ 25.2
Yes
Step-by-step explanation:
Cost of shirt = $14
Total Amount to spend ≤ $35
After shirt purchase :
Let amount left = x
x + 14 ≤ 35
x ≤ 35 - 14
x ≤ $21
B.) discount on shirt sale = 30%
(100% - 30%) of $14 = 0.7 * $14 = $9.8
x ≤ 35 - 9.8
x ≤ 25.2
C.)
Cost of Jean = 23
25.2 > 23
Hence, there is enough money

shasta claimed that the equation x^2+25=0 can be solved by using its factored form of (x+5i)^2=0, and that -5i is the only zero for this function. which statement is true?
Answer:
The given equation will have two roots as +5i and -5i
Step-by-step explanation:
Shasta claimed that the equation x^2+25=0 can be solved by using its factored form of (x+5i)^2=0, and that -5i is the only zero for this function
The given equation is [tex]x^2+25 =0[/tex]
This clearly shows it will have complex roots, and since it is a quadratic equation it will have 2 complex roots
[tex]x^2 = -25 \\x = \sqrt{-25} \\x= \sqrt{-1}* \sqrt{25}\\[/tex]
[tex]x = i\sqrt{25}[/tex]
x = ± 5i
It will be false to say that -5i will be the only complex root to this equation.
The given equation will have +5i and -5i as its roots.
Lets verify
x = +5i
[tex](5i)^2 + 25 \\25i^2 + 25 \\25(-1) + 25\\-25 + 25 = 0[/tex]
x = -5i
[tex](-5i)^2 + 25 \\25i^2 + 25 \\25(-1) + 25 \\-25 + 25 \\ = 0[/tex]

Answer:
Marion is 24, Judy is 12
Step-by-step explanation:
Let j represent Judy's age now. 6 year ago, the relation was ...
3(j -6) = (2j) -6
3j -18 = 2j -6 . . . . . eliminate parentheses
j = 12 . . . . . . . . . . . add 18-2j
2j = 24 . . . . . . . . . Marion's age now
Judy is 12; Marion is 24.

Answer:
= − 7 /1 1 in fraction form
Step-by-step explanation:
STEP 1: Multiply by 1
1 + 1 0 + 2 5 = 1 8
+ 1 0 + 2 5 = 1 8 STEP 2: Combine like terms
+ 1 0 + 2 5 = 1 8
1 1 + 2 5 = 1 8 STEP 3: Subtract 2 5 from both sides of the equation
11x+25=18
1 1 + 2 5 − 2 5 = 1 8 − 2 5
STEP 4: Simplify by subtracting the numbers
1 1 + 2 5 − 2 5 = 1 8 − 2 5
11x+25−25=18−25 1 1 = 1 8 − 2 5 1 1 = -7
STEP 5: Divide both sides of the equation by the same term 1 1 = − 7 11x/ 11x = −7/ 1 1 (set up as a fraction) STEP 6: Cancel terms that are in both the numerator and denominator
= − 7 /1 1 SOLUTION
= − 7 /1 1
