Answer:
Step-by-step explanation:
Assuming you were given the function and you were asked to find g(-2).
The we substitute x=-2 to get:
We evaluate to get:
We now multiply to get:
This finally simplifies to
Answer:
14) 21.136505024965 m
15) 43.076759215619 km
Step-by-step explanation:
14)
let h be the height of the lighthouse:
tan(41.3) = 18.7/h
Then
h = 18.7÷tan(41.5)
= 21.136505024965 m
………………………………………
15)
90-71.4 =18.6
Let s be the distance that the plane flew
towards the south:
tan(90 - 71.4) = s/128
Then
tan(18.6) = s/128
Then
s = tan(18.6)×128
= 43.076759215619 km
The answer is x=2, and y=10 now go and get that A+!
Answer:
2 intersections
Step-by-step explanation:
The greatest possible number of intersections of these graphs is 2 intersections. This is because a quadratic equation always appears on a graph as a parabola, either facing up or down. a Linear expression is a straight line, when placed in the same graph as a parabola only three things can happen. It can completely miss the parabola. It can pass through only one half of the parabola (thus intersecting at one point only), or lastly it can go through both halves of the parabola (intersecting at 2 points) as shown in the picture below.
