2v2 -5v +3 = 0 how did I do this?

Answers

Answer 1

Answer: $2v2 -5v +3 = 0 \n \n\Delta = b^(2)-4ac = (-5)^(2)-4*2*3= 25-24=1\n \nv_(1)=(-b-√(\Delta ))/(2a) =(5- √(1 ))/(2*2)=(5- 1)/(4)= (4)/(4)=1\n \nv_(2)=(-b+√(\Delta ))/(2a) =(5+ √(1 ))/(2*2)=(5+1)/(4)= (6)/(4)=(3)/(2)=1(1)/(2)$

What is the tenth term in the sequence 5,8,11,14...?

A. 29

B.32

C. 35

D. 38

Answers

cause 5+3+8, 8+3=11 11+3=14, so 14+3=17 17+3=20, 20+3=23 23+3=26 26+3=29 29+3=32
so its 5, 8, 11, 14, 17, 20, 23, 26, 29, 32
so the answer is 32

Since the sequence is adding 3 to each number, 5+3=8, 8+3=11, 11+3=14, 14+3=17, 17+3=20, 20+3=23, 23+3=26, 26+3=29, 29+3=32, 32 is the answer since it is the tenth term in sequence.

The function represents exponential growth (since the exponent is positive).

The percentage increase is, if I'm not mistaken, 181.3% (since 710 is just a constant, we don't need to worry about that - it won't affect the growth rate of the function)

5. the price of an ipod dropped from $299.99 to $180.55. what was the percent decrease in price? (round to nearest hundredth percent.)

Answers

If you would like to know what was the percent decrease in price, you can calculate this using the following steps:

x% of $299.99 is $180.55
x% * 299.99 = 180.55
x/100 * 299.99 = 180.55
x = 180.55 * 100 / 299.99
x = 60.19%

100% - 60.19% = 39.81%

The correct result would be 39.81%.
