The first option 0.65 might be right
Suppose time Olive is traveling is x hours.
distance=speed×time
Olive's speed=30 miles per hour
time= x hours
Therefore, Olive's distance at time x will be given by:
distance=30×x= 30x
The right equation is:
Miles=30x
Answer:
At a point on the ground 50 feet from the foot of a tree, the angle of elevation to the top of the tree is 53°. Find the height of the tree to the nearest foot.
I got 50xtan53 = 66.35 nearest foot ? would I use tan or sin since I'm finding the foot of the tree

<u>ANSWER</u>
<u>EXPLANATION</u>
When a quadratic equation is in the vertex form,
the equation of axis of symmetry is simply
The given quadratic equation is
We can rewrite this as
We now compare to
We have
Therefore equation of axis of symmetry is:
Assuming you mean for x=3
f(3)=2(3)^2-3(3)+4
f(3)=2(9)-9+4
f(3)=18-5
f(3)=13
it is 13
