Answer:
26.4 m
Step-by-step explanation:
The sine of an angle is the ratio between the opposite side of the angle and the hypotenuse. Hence,
sin 40° =
=
c =
<u> c = 26.4 m (3 sf)</u>
Make a graph on f(x)=−3/2(x+1)(x−5)
1 answer:
Answer:
explanation below
Step-by-step explanation:
f(x) = −3/2(x+1)(x−5) = -3/2 (x²-4x-5) = -3/2 (x²-4x+4-9) = -3/2 ((x-2)² - 9)
f(x) = -3/2 (x-2)² + (-3/2)*(-9) = -3/2 (x-2)² + 13.5
There are points to be referenced for the graph:
vertex (2 , 13.5) axis of symmetry: x = 2
roots: (-1 , 0) (5 , 0)
-3/2 : curve downward
