Lisa puts 8,000 in an account that earns 12%simple annual interest. if she leaves her money in the account for 4 years how much interest will she earn

She earns $3840

Step-by-step explanation:

I = interest amount

p = principal ($8000)

r = interest rate (12%)

t = number of yrs (4yrs)

I = (8000×12×4)÷100

= 384000÷100

= 3840

x=-2

infinite number of lines, so there is an infinite number of equations.

step-by-step explanation:

there are an infinite number of line that passes through the point (-2,5)

x=-2   is one line that passes through the point

y = 5 is another line that passes through the point

(these two lines are perpendicular to each other).

since the number of   numbers are infinite and the slope is the ratio of two numbers,(change in y over change in x) we can have an infinite number of slopes.     our only condition is that it passes through the point (-2,5)

the equation cos(35) =a/25 can be used to find the length of bc what is the length of bc? round to the nearest tenth
