2) 50 degrees
3) a- 58 degrees, b- 32 degrees
Step-by-step explanation:
78, 52, and the number inbetween = 180
if u find the inbetween number it will be vertically opposite to a
Answer:
2
Step-by-step explanation:
Substitute y=2x in the first equation into the second.
The second equation then becomes;
x = -(2x)+6
x = -2x+6
Collectiing like terms, more -2x to the left,
x+2x =6
3x=6
x=
x= 2
Answer:
The volume of the cylinder V = 942 cm³
Step-by-step explanation:
<u><em>Step(i):-</em></u>
Given that the graph
The height of the cylinder (h) = 12cm
The diameter of the cylinder d = 10cm
The radius of the cylinder
d = 2r
r = 
r = 5 cm
<u><em>Step(ii):-</em></u>
The Volume of the cylinder
V = π r² h
V = π (5)²(12)
V = 300π cubic centimeter
V = 300 × 3.14
V = 942 cm³
<u><em>Final answer:-</em></u>
Volume of the cylinder V = 942 cm³
<span>A(t) = −(t − 8)2 + 535
You would like to find the maximum of this function:</span> −(t − 8)^2<span>This part is always negative or zero as a number squared cannot be negative and you multiply by -1: Thus the maximum of this part MAX:</span>−(t − 8)^2=0
<span>The max will be when t=8 and its value is 535
