Answer:
t = 2
Step-by-step explanation:
Notice that this expression for the projectile's path is that of a quadratic function with negative leading term. The graph of it therefore consists of a parabola with the branches pointing down (due to he negative leading coefficient). Therefore, the maximum of such parabola will reside at its vertex.
Recall that the formula for the position of the vertex in a general parabolic function of the form: 
, is given by the expression: 
In our case, the variable "x" is in fact "t", the leading coefficient (
) is -5, and the coefficient for the linear term (
) is 20.
Therefore, the maximum of the path will be when 
Answer:
x=25
Step-by-step explanation:
2x+40=90
90-40=50
50 divided by 2 is 25
x=25
Answer: $61.48
Step-by-step explanation:
First, let’s find her cost before tax by adding everything she bought together.
50+5+3=58
Then, find the cost of sales tax.
Convert 6% to a decimal
6/100=0.06
Multiply the total cost by the decimal
58*0.06=3.48
Add the tax and total cost together
58+3.48=61.48
So the total cost with tax is $61.48
Hope this helped!
As you probably know, the term <em>divided </em>designates to the mathematical operation division. So, to express such expression, simply divide p by 6:
p/6
So, first you need to think 'what is the highest degree?'
Then you need to figure out how many terms you have
polynomial- four or more terms
trinomial- three terms
binomial- two terms
