X² + 16x + 64 = 0
x² + 2 * x * 8 + 8² = 0
Now, sing the formula (a + b)² = a² + 2ab + b² , we get,
(x + 8)² = 0
Square rooting on both sides, we get,
x + 8 = √0
x + 8 = 0
x = - 8 <== that's your answer!!!
Answer: Choice C) 10.5
The distance from A to C is 7 units (count out the spaces between the two points, or subtract y coordinates 4-(-3) = 4+3 = 7)
Let AC = 7 be the base of the triangle. You might want to rotate the image so that AC is laying horizontally rather than being vertical.
Now move to point P. Walk 3 spaces to the right until you land on segment AC. This shows that the height of the triangle is 3 when the base is AC = 7.
base = 7, height = 3
area of triangle = (1/2)*base*height
area of triangle = 0.5*7*3
area of triangle = 10.5 square units
Answer:
The amount after 8 years is $ 16,031.579
Step-by-step explanation:
Given as :
The Principal invested = $ 16000
The rate of interest compounded daily = 9 %
The time period = 8 years
Let The amount after 8 years = $ A
<u>From Compounded method </u>
Amount = Principal invested × 
Or, Amount = 16000 × 
Or, Amount = 16000 × 
∴ Amount = $ 16,031.579
Hence The amount after 8 years is $ 16,031.579 Answer
