19) The question is, for which n is n^(4t) equal to 16^(2t)
n^4t = n^(2*2t) = (n^2)^2t
so n^2 must be 16, so n=4
20) Fill in what you know:
<span>f(1) = -2f(0)+3 = -4+3 = -1
</span><span>f(2) = -2f(1)+3 = 2 + 3 = 5
</span>
21) The average speed is the total displacement divided by the total time. In this case the total time is easy, it is 5 seconds (from 5 to 10). The displacement will be d(10)-d(5).
d(10) = 0.8*100 = 80
d(5) = 0.8*25 = 20
So average speed is (80-20)/5 = 12
The answer would be 74,000. hope this helps
(3.7 x 10 to the 4th power) x 2 as well = 74,000
Both formulas equal to y, so they are equivalent to one another.
3x-5 = -3x+4
+5. +5
3x = -3x+9
+3x. +3x
6x = 9
/6. /6
x = 1.5
3(1.5)-5 = y
4.5-5
y = -0.5
Answer:
-4m-17
Step-by-step explanation:
g(2m+7) = -2*(2m+7) -3
= -4m -14 -3
= -4m -17
