Answer:
The budget in 2010 is $4453.10915 billion
Step-by-step explanation:
We are given exponential function as

where t is the time in years since 1950
now, we can find time in 2010
t=2010-1950=60
now, we can plug t=60
and we get

we get

So, the budget in 2010 is $4453.10915 billion
Answer:
160°
Step-by-step explanation:
Take notice that m∠1 and m∠2 are supplementary angles, meaning their angle measures will add up to 180°.
Since we know m∠2, we can find m∠1 easily.
180-20=160°
Hope this helped!
For number 19:
"at least 150" means either 150 ≤ ? or ? ≥ 150
plus 3 so +3x
The answer would be 150 ≤ 100 + 3x
Number 20:
A is at -2.5. The inverse is the opposite so 2.5
