Answer:
The volume of the figure is approximately 1244 in³
Step-by-step explanation:
The figure is formed by a rectangular prism and a hemisphere, therefore its total volume is formed by the the sum of the volume of each of these forms. The volume of a rectangular prism can be found by using the expression:
While the volume of a hemisphere is given by:
The radius of the hemisphere is the difference between the total length of the figure and the length of the prism, therefore:
We can now find the volume of the figure:
Answer: x=-2 y=13
2(-2)+1=-3 check
-2-2=-4 check
Step-by-step explanation:
Horner's method:
2 1 -3
1 -2 -4
delta = det(
2 1
1 -2) = 2×-2 - 1 = -5
x = det(
-3 1
-4 -2)/-5 = (-2×-3-1×-4)/-5 = -2
y = det(
2 -3
1 -4)/-5 = (-8+3)/-5 = 1
Or by elimination
x = 2y - 4 from adding 2y=2y to second eqn
2(2y-4)+y=-3 by substituting for x in first.
4y-8+y=-3
5y=8-3=5
y=1
x=2y-4=2-4=-2
