Height of tree 3 years ago: 24 inches
Height of tree now: 54 inches
54-24 = 30
The tree grew 30 inches in 3 years.
So on average it grew 10 INCHES PER YEAR.
Let me know if this helps!
Answer:
A. 4(0*8)=x
B. x=0
C. I used the zero product property
Step-by-step explanation:
For part B, I did 0*8 which is 0
then 0*4=0
this means that x=0
A is the correct answer because he did not ask the whole class.
Answer:
A= 429
B= 50
Explanation:
A+B= 479 (take away)
A-B= 379
A-A+B+B= 479-379 (simplify)
2B= 100
I think you know how to do it now..
B=50
A=50+379 ---> 429
This is the substitution method, there are other ways of doing it- and I tried to make this simple. Hope this helped!
H(t) = -16t² + 144
When will the object hit the ground? This means that the height will equal to 0.
h(t) = 0
0 = -16t² + 144
16t² = 144
t² = 144/16
t² = 9
√t² = √9
t = 3
The object will hit the ground after 3 seconds.
