Answer:
5
Step-by-step explanation:
4.5*10^-8/ 9*10^-9
1) Reduce the fraction, express 9 as a product of multiplying 4.5*2
4.5*10^-8/4.5*2*10^-9
2) Then notice the common factor of numerator and denominator( 4.5) , get rid of it in both numerator and dnominator
3) 10^-8/ 2*10^-9= 1/2*(10^-8/10^-9)= 0.5* (10^-8/10^-9)
10^-8/10^-9= 10^(-8-(-9))= 10^1=10.
so 0.5*10=5 (it is the answer written in scientific form)
The last option: In his recursive formula, he should have the term an−1 instead of −4 to get an=an−1−3.
Answer:
She drew the graph too steep, if she is going down at a constant rate of 300 ft per hour, at 1 hour she would be at 2,700 ft. it would take her about 10 hours to get down the mountain.
Answer:
its b i took the test
Step-by-step explanation:
f(x) = -3x2(x - 3)(x + 4)3(x2 + 5)
If (x - a) if a factor of polynomial P(x), then a is a zero of P(x).
x = 0
x = 3
x = -4, three times
x = ±√5
