I think you have to sketch the graph
Answer:
x = 8.39
y = 55.2
Step-by-step explanation:
9² + 1² - 2(9)(1)cos(50) = x²
x = 8.39
9/sin(y) = x/sin(50)
sin(y) = 0.8215200692
y = 55.23724927
Answer:
Part A: Triangles GCB and PBE
Part B: They're similar because they have the same internal angles.
Part C:
250/400 = BE/450
112500/400 = BE
BE = 281.25 ft
250/400 = PE/350
87500/400 = PE
PE = 218.75 ft
To
answer this set of questions, all we have to do is just to substitute the value
of x in F(x) to the given f(x) equation.
By
substitution and following PEMDAS rule:<span>
F(-1)=2(-1)³-3(-1)²+7=5</span>
F(1)=2(1)³-3(1)²+7=6
F(2)=2(2)³-3(2)²+7=11
Therefore the answers
are 5, 6 and 11.
