The shape of the cross section is a triangle. Therefore, the answer is the second option: Triangle.
A rectangular pyramid is a pyramid that has a rectangle as its base. Therefore, its base has four sides. The rectangular pyramid also has four triangles that coming together in its apex. So, if the rectangular pyramid is<span> sliced so the cross section is perpendicular to its base and passes through its vertex, the cross section obtained is a triangle.</span>

69.12
Step-by-step explanation:
2sqrt(41) because 8^2+10^2=x^2 and solve for x
Answer:
11.4 x 10 ^ 6
Step-by-step explanation:
- First, you have to convert 3.8 x 10^5 out of scientific notation. To do that, multiply 3.8 * 10^5, you'll get 380,000. This is the weight of each whale.
- Now multiply the weight of each whale times 30. 380,000 * 30 = 11,400,000
- Convert back to scientific notation. 11.4 x 10^6
Answer: Option A is correct that is 
Explanation:
we will substitute the values of n in given expression
when substituting n=1 we get in =
when n=2 we get 
when n =3 we get 
;3 factorial that is 3! = 3 *2*1 = 6
when n=4 we get 
;4! = 4*3*2*1 = 24
Note: factorial means the product of the terms getting multiplied till 1
suppose n! will be equal to n(n-1)(n-2)(n-3).......1
