Answer:
See below
Step-by-step explanation:
(0,16) - y axis
(2, -12) - IV
(-1, 2) - II
(3, 0) - x axis
(36.7, 3.9) quadrant I
(-5/8, -5 1/3) - III
Answer:
$972.8
Step-by-step explanation:
$12.80 x 76 = $972.8
Jason worked forty minutes every day and worked three hours and twenty mins (200 mins in total)
Answer:
a) Sinusoidal functions are y = a sin [b(x-h)] + k (or)
y = a cos [b(x-h)] + k
Where a is amplitude a= (max-min)/2=(16-2)/2=7
period p= 2π/b
b=2π/30
Horizontal transformation to 10 units right h=10
k= (max+min)/2=(16+2)/2=9
h = 7 cos [π/15(t-10)]+ 9
b) t=10min=600 sec
substitue in the above equation
h=5.5m
You wan't to get it into a format of (x+a)(x+b)=0
where a+b = 3 (the one from the 3x)
and where a*b= -4 (from the last -4)
(x+4)(x-1)=0
See how 4+(-1) = 3 and (4)(-1) = -4
now find what values of x would make the equation equal 0
x=-4
(-4+4)(-4-1) = (0)(-5) = 0
x=1
(1+4)(1-1) = (5)(0) = 0
