Answer:
Inequality Form: m > 7/12
Interval Notation: (7/12, ∞)
Answer:
Step-by-step explanation:
Find derivative of the function:
y' = -2·sin(2·x)
-2·sin(2·x) = 0
x1 = 0
x2 = 3.142
f(0) = 1
f(3.142) = 1
Answer
fmin = 1, fmax = 1
Answer:
Step-by-step explanation:
200ft (1mile/5,280ft) 60ft/1hr 200×60/5,280 = 2.27272727273
and round it to the2 decimal is 2.27
Answer:
C
Step-by-step explanation:
(x+3)/3 =(y+2)/2
x/3 +3/3 = y/2 +2/2
x/3 +1 = y/2 +1
x/3 = y/2
Answer:
x=8.499
y=0.167
Step-by-step explanation:
the equation says:x^2-9y^2=72....(1)
x+3y=9.......(2)
divide (2) from (1),it becomes:
x-3y=8
making x subject of formula,
x=8+3y....(3)
submitting (3) into (1),it becomes
(8+3y)^2-9y^2=72
64+48y=72
48y=72-64=8
y=8/48=0.167......(4)
submitting (4) into (2),it becomes
x+3(0.167)=9
x+0.501=9
x=9-0.501
x=8.499
