Answer:
Calculate 93% of 29.96.
Your final answer is approximately 27.86
A. yes...it is a function because there is no repeating x values.
B. (5,2)(6,5)...slope = (5 - 2) / (6 - 5) = 3
y = mx + b
slope(m) = 3
(5,2)...x = 5 and y = 2
now we sub
2 = 3(5) + b
2 = 15 + b
2 - 15 = b
-13 = b
so the equation is : y = 3x - 13
when x = 7
y = 3(7) - 13....y = 21 - 13....y = 8
f(x) = 2x + 13...when x = 7
f(7) = 2(7) + 13...f(7) = 14 + 13.....f(7) = 27
the function has a greater value
C. f(x) = 2x + 13....when f(x) = 75
75 = 2x + 13
75 - 13 = 2x
62 = 2x
62/2 = x
31 = x
Answer:
20/(9π) m/min ≈ 0.707 m/min
Step-by-step explanation:
The rate of change of height is the rate of change of volume divided by the surface area. Of course, the surface area is given by πr², where r = d/2 = 3 m.
dh/dt = (dV/dt)/A = (20 m³/min)/(π(3 m²))
dh/dt = 20/(9π) m/min ≈ 0.707 m/min
It is equivalent to this= 36 x 54 k
Divide that number by 12 for the answer
