Answer:
28
Step-by-step explanation:
because in this series the gap between number is gradually increasing from 1 and so this times its the turn of number 7 so 21+ 7 = 28
Answer:
12/16
Step-by-step explanation:
multiply 3/4 in the numerator and denomanator by 4 and you get 12/16
The perimeter of the triangle is 10. Hope this helps and Brainliest would be appreciated
Let X(t)=the position function with respect to time, t.
We're given:
X(0)=12 (from graph)
v(0)=0
X(2.5)=7
There is enough information to construct X(t).
In general,
X(t)=kt^2+v(0)(t)+x0
where initial velocity=v(0)=velocity at time 0 = 0 (given)
x0=initial position at time 0 = 12 (from graph)
Substituting values, the position equation is
X(t)=kt^2+12
Substituting given value X(2.5)=7 => 7=k(2.5^2) + 12
Solve for k to get k=(12-7)/6.25 = -4/5
The position equation now becomes
X(t)=-4t^2/5+12
For t=25,
X(25)=-4(25^2)/5+12=-500+12 = 488 m
Answer:
7 years
Step-by-step explanation:
Use the formula I=Prt
Convert 4% to a decimal. 4% = 0.04
1428 = 5100(.04)t
1428 = 204t
1428/204 = 204t/204
t = 7 years
