Answer:
It is the first choice.
Step-by-step explanation:
This is a sequence where
the next term is obtained by adding 6.
first term = -9 + 6(0) = -9
second term = -9 + 6(1) = -3
third term = -9 + 6(2) = 3
4th term = -9 + 6(3) = 9
and 81 = -9 + (6*15).
So the answer is Sigma (-9 + 6n) from n= 0 to n = 15.
This is easy all you have to do is use the formula of the volume which is v=l.h.w
(X+9)(x+4)(x+5)= v
(X+9)(x^2+9x+20)
X^3+18x^2+101x+180=v
Answer:
The answer would be c)85 FEET
Step-by-step explanation:You start with the deepest section(-135) and add the shallowest point(50). the result is an 85 foot difference.
Answer:
23.6 degrees
Step-by-step explanation:
Here, sin(<XZY) = 6/15 = 2/5
So, <XZY = arcsin(2/5) = 23.6
