Answer:
114.89 degrees
245.11 degrees
Step-by-step explanation:
cos is negative in the second and third quadrant ("pointing" on the x-axis to the left).
so, the first answer for the second quadrant is
114.89 degrees.
the answer for the third quadrant is then backwards the same angles from a full 360 degree rotation
360 - 114.89 = 245.11 degrees
You would get a decimal that could be rounded down to 11
We know that
surface area of cylinder=2*[area of the base]+perimeter of base*height
area of the base=pi*r²
r=3 m
area of the base=pi*3²----> 28.26 m²
perimeter of the base=2*pi*r
r=3 m
perimeter of the base=2*pi*3----> 18.84 m
surface area=226.08 m²
226.08=2*[28.26]+18.84*h----> 18.84*h=226.08-2*28.26
18.84*h=169.56-------> h=169.56/18.84-----> h=9 m
the answer is
9 m
35p + 25
A) 5(5 + 3p + 4p)
= 25 + 15p + 20p
= 35p + 25
B) 5(15p + 5 + 20p)
= 75p + 25 + 100p
= 175p + 25
C) 5(5 + 7p)
= 35p + 25
D) 5(4p + 3p + 5)
= 20p + 15p + 25
= 35p + 25
So, in conclusion, option B is incorrect because it does not equal to: 35p + 25 whereas all the other options do.
Answer:
3,5, Minimum
Step-by-step explanation:
y=x²-6x+14
y=(x²-2*3x +3²-3²)+14
y=(x²-2*3x+3²)+14-9
y=(x-3)²+5
a=1
p=3
q=5
a>0 ⇒ vertex is minimum
V(p,q) ⇒ V(3;5)
