Use the quadratic formula to determine the exact solutions to the equation. 6x^2+4x-3=0

X=_____. Or x=_______

Answers

Answer 1
Answer:

X1=(-2-√22)/6

X2=(-2+√22)/6
Answer 2
Answer: for ax²+bx+c=0
x= (-b+/- √(b^2-4ac) )/(2a)

6x²+4x-3=0
a=6
b=4
c=-3

subsitute
x= (-4+/- √(4^2-4(6)(-3)) )/(2(6))
x= (-4+/- √(16+72) )/(12)
x= (-4+/- √(88) )/(12)
x= (-4+/- 2√(22) )/(12)
x= (-2+/- √(22) )/(6)

x= (-2+ √(22) )/(6) or x= (-2- √(22) )/(6)

aprox x=0.448403 or -1.11507

How do you get the answer 3a -5 from: -3a - (5-6a)?

Answers

The key here is to remember how to get rid of the parentheses.

The 'minus sign' ( - ) before the parentheses says that in order to
get rid of them, you have to change the sign of each term inside.

-3a - (5 - 6a) is the same as

-3a -5 + 6a

Add up the (-3a) and the (+6a) and you have +3a .

So the whole thing becomes 3a - 5 . 

-3a - (5-6a)=-3a-5+6a=3a-5

Write a program that calculates how many days it takes to accumulate at least $1,000,000 if someone deposits one penny on the first day, two pennies the second day, four pennies on the third day and continues to double each day. The output should display the number of days

Answers

Answer:

Step-by-step explanation:

Let's do this in Python

day = 1

balance = 0

deposit = 0.01  # first deposit is 1 penny

while balance < 1000000: # execute the loop as long as balance is less than a million dollar

    balance += deposit

    deposit = deposit * 2 # double the deposit for the next time

    day += 1 # add one to day for the next day

print(day) # print out result once loop ends
