Here is the answer to you question.
Answer:
The answer is (60,90)
Step-by-step explanation: Because if u think white is added by 12 like 24+12 is 36 same as for Pink 18+18 is 36 adding up
For this case we have the following equation:
h (t) = - 12t2 + 36t
When the object hits the ground we have:
- 12t2 + 36t = 0
We look for the roots of the polynomial:
t1 = 0
t2 = 3
Therefore, the time it takes the object to hit the ground is:
t = 3 s
Answer:
the time when the object hits the ground is:
t = 3 s
Account B will cost less because
Account A will cost 0.2*20= $4
Account B will cost
0.1*20 +1.5= 2+1.5= $3.5
This is a trapezoid and the trapezoid formula is b1 plus b2/ 2 times height.
17 plus 5 is 22. Divided by 2 is 11.
Now, we have to multiply 11 by the height : 5.
11 times 5 is 55 and that is your area. 55 units squared.
