Vertex is highest point
ok so the t value of the vertex of a function in the form
f(x)=at^2+bt+c is
-b/2a
find t value
h(x)=-16t^2+50t+6
a=-16
b=50
-50/(2*-16)=1.5625
round
1.6 seconds
max height
input 1.6 for t and evaluate (for more precice, input 1.5625 for t)
max height is 45 feet
seems to be
b=initial velocity
c=intial height
a=-16
eqation is
h(t)=-16t^2+70t+5
vertex is -70/(2*-16)=2.1875
input for t to get max height
82 feet
answers are
1.6 seconds
45 feet
82 feet

Step-by-step explanation:
Answer:

Step-by-step explanation:
Given
Represent travel guide with T and Fictions with F


Required
Determine the probability that one of both was selected
This implies that (1 travel guide and 1 fiction) or (1 fiction and 1 travel guide)
The probability is is calculated as thus:

In probability, the above formula can be translated to







Answer:
A) .9071 kilograms
Step-by-step explanation:
there is 1000 grams per kg
there is 907.1 grams so thats less then a kg
so its A) .9071 kilograms
Answer:
Step-by-step explanation:
the function opens down and has a negative value.
