Diameter is 2r, or 18.8 ft
Circumference is 2*pi*r, or 59.1 ft
Answer:
432
Step-by-step explanation:
60 minutes is one hour
60 times 4=240
=240+192=432
Please use " ^ " to indicate exponentiation: x^2 + 3x - 4 = 0
Here, a = 1, b = 3 and c = -4.
The formula for the discriminant is b^2 - 4(a)(c).
Substituting the given values of a, b and c, we get:
(3)^2 - 4(1)(-4)
Evaluating this, we get 9 + 16 = 25.
The discriminant is 25.
-3 plus or minus √25
Taking this further, x = ------------------------------------
2
-3 plus or minus 5
or: x = -------------------------------- => {-4, 1} (solutions)
2
Ten and negative 2 will be in q1 and negative 3 and 8 will be in q2
He would have $4131 left from $5400 with a decrease with 23.5%
