Find the product of 3a+5 and 2a^(2)+4a-2

Answers

Answer 1
Answer: The answer is 6a3+22a2+14a10
My steps:
(3a+5)(2a^2+4a−2)=(3a+5)(2a^2+4a+−2)=(3a)(2a^2)+(3a)(4a)+(3a)(−2)+(5)(2a^2)+(5)(4a)+(5)(−2)=6a^3+12a^26a+10a^2+20a−10=6a^3+22a^2+14a10

The value of a boat, in dollars, x years after its purchase is represented by the function.f(x)=10,000(0.73)^x



What is the average decrease in value per year between years 1 and 2?

Answers

Given the function f(x) = 10000(0.73)^x

Where y is The value of a boat, in dollars, x years after its purchase 
at x = 1
f(1) = 10000(0.73)^1
f(1) = $7300  
at x = 2
f(2) = 10000(0.73)^2
f(2) = $ 5329  
so the decrease
D = $7300 - $ 5329
D = $ 1971

 

Answer:

The correct answer is $1971.

You have to find LCD (lowest common denominator) in this case it will be 5x:

(u)/(x)+(5u)/(x)- (u)/(5x)=(5*u)/(5x)+(5*5u)/(5*x)- (u)/(5x)=(5u+25u-u)/(5x)=(29u)/(5x)

The peak value of sinusoidal ac current of 4.78rms is a. 5.45 amp b. 6.76 amp c. 4.56 amp d. 4.78 amp​

Answers

Answer:

To find the peak value of a sinusoidal alternating current given its RMS (Root Mean Square) value, you can use the relationship between peak value and RMS value for a sinusoidal waveform.

The relationship is given by:

Peak Value = RMS Value * √2

In this case, the RMS value is 4.78 amp. Plugging this into the equation, we get:

Peak Value = 4.78 amp * √2 ≈ 6.76 amp

Therefore, the correct answer is option b) 6.76 amp.

The deposits Ginny makes at her bank each month form an arithmetic sequence. The deposit for month 3 is $150, and the deposit for month 5 is $180. Answer the questions below and show all work.

Answers

Answer:

d=$15,

Explicit formula:  a_n=120+(n-1)15

a_(12)=285

At 27 month Ginni make a deposit at least $500.

Step-by-step explanation:

Given that the deposits Ginny makes at her bank each month form an arithmetic sequence. The deposit for month 3 is $150, and the deposit for month 5 is $180.

we have to find the common difference i.e d

-- , -- , $150, x, $180 , -------

Let $x be the 4th deposit.

∴ x-150=180-x ⇒ 2x=330 ⇒ x=165

Common difference,d=165-150=$15

Let us find the first tem i.e the value of a

a_3=a+(3-1)15

150=a+30\thinspace gives\thinspace a=120

Explicit formula for arithmetic sequence is

a_n=a+(n-1)d

a_n=120+(n-1)15

Now, we have to find the amount of Ginni in 12th deposit i.e n=12

a_(12)=120+(12-1)15

⇒  a_(12)=120+165=285

Now, we have to find at what month Ginni make a deposit at least $500.

a_n=120+(n-1)15

500=120+(n-1)15

n-1=(380)/(15)

n=26.33\sim27

hence, at 27 month Ginni make a deposit at least $500.

1. 15 dollars
2. Deposit=15*month+105
3. Deposit=15*12+105=$285
4.
500=15*month+105
395=15*month
26.33=month
Round up to 27 for the nearest whole month, so month 27.

Hope this helps!
