Answer: 360
Step-by-step explanation:
310 + 50 = 360
Answer:
See the graph and explanation below.
Step-by-step explanation:
For this case we have the following function:
We can calculate some points in order to see the tendency of the graph, we can select a set of points for example 
and we can calculate the values for f(x) like this
x=-2
x=-1.5
x=-1
x=0
This point correspond to the y intercept.
x=1
x=2
We don't have x intercepts for this case since the functionnever crosses the x axis.
And then we can see the plot on the figure attached.
Answer:
37.8metres
Step-by-step explanation:
The arc of the arrow can be modeled by the equation:
y=-0.02x²+0.65x+4
Where x is the horizontal distance (in meters) from Linda and y is the height (in meters) of the arrow.
The arrow hits the ground when its height (y) is zero.
Therefore, we determine the value(s) of x for which:
y=-0.02x²+0.65x+4=0
Using a calculator to solve the quadratic equation:
x=37.79 or -5.29
Since the distance cannot be a negative value, we ignore -5.29.
The distance from Linda when the arrow hits the ground is 37.8metres (to the nearest tenth)
yes, it does not matter if the y is at the beginning or at the end. However, most teachers usually prefer to have the y at the beginning as it is easier to read.
