Step-by-step explanation:
The volume of the right pyramid can be calculated using formula
You are given
Then
Answer:
Step-by-step explanation:
We have been given that the base area of a right pyramid with hexagonal base is 7.4 square units. The pyramid has a height of 6 units.
To find the volume of the given pyramid we will use formula:
Therefore, the volume of given hexagonal pyramid is 14.8 cubic units.
Answer:
2x-15
Step-by-step explanation:
x+2x-15=90
3x-15=90
3x=90+15
x=105/3
the other angle is 55
if f(x+5)=x^2 +kx+30, k= ?
find the smallest zero of f(x+5). x=?
Hope this helps :)

Answer:
k=13
x= -10
Step-by-step explanation:
f(x)=x²+3x-10
f(x+5)=
=(x+5)(x+5)+3(x+5)-10
=x²+10x+25+3x+15-10
=x²+13x+30
0=x²+13x+30
0=(x+3)(x+10)
x= -3 or -10
-10< -3
smallest zero is -10
