a + b = 60 (1)
b < a with 6 ⇒ b = a - 6 (2)
(1), (2) ⇒ a + a - 6 = 60 ⇒ a + a = 60 + 6 ⇒ 2a = 66 ⇒ a + 66:2 ⇒
⇒ a = 33 (3)
(2), (3) ⇒ b = 33 - 6 ⇒ b = 27
So, the numbers are : a = 33, b = 27
Answer:
y = x-3 is the equation
Step-by-step explanation:
If two lines are perpendicular, the product of their slopes is -1
The general equation form of a straight line is;
y = mx + b
Fro the equation;
y = -1x + 2
The slope is -1
So the equation of the perpendicular line is as follows;
-1 * m = -1
m = 1
so we can use the point-slope equation form
That would be:
y-y1 = m(x-x1)
y-3 = 1(x-6)
y-3 = x-6
y = x-6+3
y = x-3
The answer is 0.07

Answer:
16 seconds
Step-by-step explanation:
You want to find t such that h(t) = 0
h(t) = -16t^2 +4096 . . . equation for height
0 = -16t^2 +4096 . . . . .equation for height = 0
16t^2 = 4096 . . . . add 16t^2
t^2 = 256 . . . . . . . divide by 16
t = 16 . . . . . . . . . . . take the positive square root
It will take 16 seconds for the camera to hit the ground.
Circles don't have volume, but they do have area.
The area of any circle is ...
(pi) x (the circle's radius)² .
The circle's radius is 1/2 of its diameter.
So for the circle in the question,
Radius = 30-ft
Area = (pi) x (900 square ft) = <em>2,827 square feet</em> (rounded)
