Answer:
a) 12
b) 13
Step-by-step explanation:
f(x) = x^2 + 3
g(x) = 2x - 1
a) f(g(2)) = ?
g(2) = 2(2) - 1
= 4 - 1
= 3
f(g(2)) = f(3) = 3^2 + 3
= 9 + 3
= 12
b) g(f(2)) = ?
f(2) = 2^2 + 3
= 4 + 3
= 7
g(f(2)) = g(7) = 2(7) - 1
= 14 - 1
= 13
Answer: the answer is x<-4 so the correct answer choice would be D

Solving a quadratic equation:
Given a second order polynomial expressed by the following equation:
.
This polynomial has roots such that , given by the following formulas:
In this question:
So
Sincce is negative, there are no solutions, which means that those graphs do not intersect.
Answer:
41.16 m³
Step-by-step explanation:
Volume = area triangle x height
1/2(2.8x4.2) = 1/2( 11.76) = 5.88
5.88 x 7 = 41.16
