Answer: - 49
Step-by-step explanation:
f(x) = -2x - 1
g(x) = - 1
fg(x) = f ( - 1) , we just put in the value of g(x) , the next thing is to substitute - 1 for the value of x in f(x) , that is
fg(x) = -2( - 1) - 1
fg(x) = -2 + 2 - 1
fg(x) = -2 + 1
Therefore : fg(-5) means we will substitute -5 for x in fg(x) , that is
fg(-5) = -2 ( + 1
fg(-5) = -2(25) + 1
fg(-5) = -50 + 1
fg(-5) = -49
Answer:
Option (b).
Step-by-step explanation:
It is given that Adrian built a structure out of 10 congruent cubes.
Volume of each cube = 8 cubic centimetres.
We need to find the total volume of the structure.
Total volume = No. of cubes × Volume of each cube
Therefore, the total volume of the structure is 80 cubic centimetres.
Hence, option (b) is correct.
Answer:
6 questions
Step-by-step explanation:
30 x 0.2 = 6
3 rows x 5 chocolates= 15 pieces per layer
15 pieces x 5 layers= 75 chocolates
Volume of cone : (1/3) * pi * r^2 * h
<span>35 = (1/3) * 3.14 * 2.4^2 * h </span>
<span>h = 35 / ((1/3) * 3.14 * 2.4^2) </span>
<span>h ≈ 5.805 in </span>
<span>h = 5.81 in
