6 because 5-2=3 and 3+3 is 6
Answer:
The answer is b or d since the radius is the square root of 4
Step-by-step explanation:
Answer:
y = 2x + 1 --> linear
y = -4x + 7 --> non-linear
Not a solution for linear system.
Step-by-step explanation:
for (a), y = 2x+1, substitute the x and y values. keep in mind, that in a linear pair, (x, y). So, for the first equation you get:
7 = 2x3 + 1. This is correct, because 6 + 1 is 7. Therefore, (a) is linear.
for (b), we have to substitute our values again. You get:
7 = -4x3 + 7, which is
7 = -12+7, which is not true. So, (b) is not linear.
This means that for the linear pair (3, 7), it does not satisfy both equations, which means that it is not a solution for the linear system.
The correct answer for the giving question it number 4
Answer:
Both volumes are the same
Step-by-step explanation:
Volume of cylinder = 

r = radius
h = height
Since area of the circle is given on top,
Area of a circle = 

We know the area is 12
12 = 
(we need to find r)
r = 
r = 1.954
Now we can find the cylinder's volume:
Volume of cylinder = 
(6)
Volume of cylinder = 72
To find the volume of the cuboid, we use
Volume of cuboid = lwh
l = length
w = width
h = height
Volume of cuboid = 6 x 4 x 3
Volume of cuboid = 72
This proves that both the volumes are the same.
