Answer:

  x ≈ −0.30685281944

Step-by-step explanation:

We assume your equation is intended to be ...

  3+4e^{x+1}=11

Subtracting 3 and dividing by 4, we have ...

  e^(x+1) = 2

  x +1 = ln(2)

  x = ln(2) -1 ≈ -0.30685281944

Item 2 An account earns simple interest. $1500 at 4% for 5 years a. Find the interest earned. b. Find the balance of the account
Verdich [7]
The account is starting off with 1500, so that will be the start value. Since it is simple interest, it will always be gaining 4 percent of 1500. Let's find 4 percent of 1500.
1500×.04= 60
The account will be growing by $60 every year.
1500+60x=y
X is the number of years. We can find the interest earned by multiplying 5, since that is the number of years we are trying to find, and 60, since that is the interest.
60×5= 300
The interest earned is $300 over 5 years.
Now let's find the balance of the account after 5 years.
1500+ 60(5)=y
1500+300=y
1800=y
The balance of the account will be $1,800 after 5 years.

one positive number is 28 less than another number. if the reciprocal of the smaller number is added to four times the reciproca
marishachu [46]
Let x represent the larger number.
  1/(x -28) +4/x = 1/6
Multiplying by the product of denominators, we have
  6x +24(x -28) = x(x -28)
In standard form, this is
  x^2 -58x +672 = 0
  (x -42)(x -16) = 0

The two numbers are (-12 and 16) or (14 and 42).
