use equation A(t) = a(1+r)^t to solve. you want to find the starting so solve for A
1000 = a(1+.03)^5
1000 = 1.1592740743a
a = $862.61

Answer:
(-3,0)
Step-by-step explanation:
To find the x-intercept set y to 0,
x^2 + 6x + 9 = 0 Now you have a quadratic equation, so you can solve it
(x + 3)(x + 3 ) = 0
x + 3 = 0
x = -3
Answer:
Square foot need to be painted, if width is equal to
feet
Step-by-step explanation:
Complete question -
Maya wants to paint one wall in her room blue. The wall is 22,9 feet high, and have no doors or windows. How many square feet need to be painted?
Solution -
The square feet need to be painted will be equal to the product of height and width of the wall i.e surface area of the wall
Let the width of the wall be
feet
Surface area of the wall 
Where H is the height of the wall in feet
W is the width of the wall in feet
Substituting the given values in above equation, we get -

Square foot.
Thus,
Square foot need to be painted
For number 3, C is the answer.
#4. D
the coefficient of x² is negative, so the graph opens downward.
the two zeros are (3,0) and (5,0)
