Answer:
y = -(1/3)x + 2
Step-by-step explanation:
Keeping in mind the equation of a line: y = mx + c
Notice three discernible points on the graph: (0,2), (3,1), (6,0).
The first and last points mentioned represent the intercept on y-axis and the intercept on x-axis respectively.
Therefore, when x = 0, y = 2. And 2 = m(0) + c
c = 2
Also, when y = 0, x = 6. And 0 = 6m + 2
6m = -2. And m = -(2/6) = -(1/3)
Therefore, y = -(1/3)x + 2
10:4 because you multiply both numbers by 2
The approximate volume of the remaining solid is
Step-by-step explanation:
we know that
The approximate volume is equal to the volume of the cube minus the volume of the cylinder
so
we have
-----> the radius is half the diameter
substitute the values
: Hope this helps :)
The reflection line is located at y = -x
For point J, x is -2, so y = -(-2), which equals 2.
When it is a reflection across Y, the X values remain the same.
Find the distance of the Y point to the reflection line,
The distance from -1 to 2 is 3 units.
The new point needs to be the same distance from the reflection line.
2 + 3 units = 5.
Point J' would be (-2,5)
Step-by-step explanation:
V=1/3hπr².
(h=3cm, r=5²cm
V= 1/3 x 3 x π x 5²
V= 25π
