If we use our trusty ti's this will be a breeze
domain is the numbers we can use
obviously we can't have negative time so therefor the domain is all positive integers (0,1,2,2.3, 3/2,3,pi...)
zeroes is when you set absolute max using ti is
remember vertex form which is
max height of something in
ax^2+bx+c form is -b/2a
-16t^2+60t+0
a=-16
b=60
-60/(2 times -16)
-60/-32=30/16=15/8=1 and 7/8 so subsitute for t
g(15/8)=-16(15/8)^2+60(15/8)=225/4=56.25=max height
zeroes is when the equation equals 0
so set it to zero
0=-16t^2+60t
factor
0=(-4t)(4x-15)
set each to zero
-4x=0
x=0
4x-15=0
add 15
4x=15
divid 4
x=15/4
so the zeros are t=0 and t=15/4
domain is all the nuumbers that can be used logically for time
logically, we cannot have negative time, so all real positive
[0,∞)
(that means from 0 to infinity includng 0 so 0<span><</span>t<∞))
range is the output
output=height
we find the min height and max height
min=0
max=56.25
so range=0 to 56.25 or
[0,56.25]
max height=56.25 ft (15/8 seconds)
zeroes=0 sec and 15/4 sec
domain=all real positive numbers including zero or [0, ∞)
range=[0,56.25]
Hello there!
Answer:
Triangle 2
Step-by-step explanation:
To determine which triangle has the bigger area, we would need to figure our the area of the triangles.
To solve for the area of the triangles, we would use the formula length × width × height or l × w × h
They gave us the information to the triangles in the question, so we would just solve.
Triangle 1: 
Triangle 2: 
When you finish solving, you would see that triangle 2 has the bigger area.
Triangle 2 would be the CORRECT answer because it has a bigger area than Triangle 1.

135
<u><em>Explanation:
</em></u>
Let's say that the amount of money in Bailey's checking account is
c dollars.
We also know that she took away $
135
From this variable and number, we can state the algebraic expression
c
−
135
