Answer:
(D) is the right answer
Step-by-step explanation:
The cross section will be a quadrilateral when the intersecting plane forms a closed four sided polygon along with the pyramid.
A triangular pyramid has four faces. So, to form four straight lines and therefore a quadrilateral, the intersecting plane must intersect all four faces.
A. In this case the plane will only intersect one side of the pyramid so four sided polygon can't be formed.
B. It will only intersect the two sides of the pyramid but the cross section will not be a quadrilateral.
C. In this case the plane will intersect three sides of the pyramid so the cross section will be a triangle not a quadrilateral.
D. In this case the plane intersects all the four faces forming a closed polygon of 4 straight lines so the cross section will be a quadrilateral.
So, the Correct Option is (D) : When the plane intersects the base and all three lateral faces of the pyramid, the cross section of the triangular pyramid will be a quadrilateral.
Answer:
The total amount after five years = $7,000
Step-by-step explanation:
<u><em>Step(i):</em></u>-
Given Esther deposited $5,000 into an account
Principal amount 'P' = 5000
Given rate of interest (R) = 8%
r = R / 100 = 0.08 per year
<u><em>Step(ii):</em></u>-
The total amount after 5 years
<u><em>Final answer</em></u>:-
The total amount after five years = $7,000
