The area of a trapezoid is the average of the bases times the height, mathematically:
A=h(b1+b2)/2, in this case:
A=3(1.25ft(12in/ft)+14)/2
A=3(29)/2
A=43.5 in^2
144 - 12g^2.
Because we don't know the value of g, there's nothing else we can do.
Answer:
75
Step-by-step explanation:
f(1) = 7
f(n) = 3f(n-1) + 3
So what you are trying to do here is find the recursive value (that's what it is called) for f(n). Computers love this sort of thing, but we humans have to do it slowly and carefully.
So let's try f(2)
That means that f(2) = 3*f(n-1) + 3
but if f(2) is used it means that you have to know f(2-1) which is just f(1) and we know that.
so f(2) = 3*f(1)+3
f(2) = 3*7 + 3
f(2) = 21 + 3
f(2) = 24
Now do it again. We now know F(2), so we should be able to find f(3)
f(3) = 3*f(3 - 1) + 3
f(3) = 3*f(2) + 3 We know that f(2) = 24
f(3) = 3* 24 + 3
f(3) = 72 + 3
f(3) = 75
hii! i just wanted to say hope you're having a fantastic day and hope that things are going well (: stay strong and stay safe!
