Answer:

50000 times

Step-by-step explanation:

Since these are given in scientific notation, we can convert them to have the same powers of 10. Converting 4*10^12 to something times 10^7, we can get 4*10^5*10^7. So we divide 400000 by 8 to see how many times larger it is than 8. So we get 50000 times as our answer.

-BARSIC- [3]

Answer:

x = .23

x = 1.43

Step-by-step explanation:

1. The root of a polynomial is when the y-value equals 0. So set the equation euqal to 0:

$3x^{2} -5x+1=0$

2. Solve with the quadratic formula and you get:

$\frac{5+\sqrt{13} }{6}$ and $\frac{5-\sqrt{13} }{6}$ which is x = .23 and x = 1.43.

What percent of 32 is 48? A.67 B.46 C.33 D.none of above

elena55 [62]

Just by giving the numbers an analisys, we are able to find the answer, specially because we have options to choose from.

32 is a big part of 48. It's more than half, which would be 24 and would correspond to 50%. Therefore, nor 46 nor 33 can be answers, because 32 is more than the half of 48, so the answer is A.

Hope it helped,

A scientist is studying bacteria and records the number of bacteria over time. The scientists determines that the function N(t)=

Cloud [144]

Answer:

(A) The number of bacteria is originally 300 and increases by 30% every hour

Step-by-step explanation:

I am assuming the function should actually read:

$N(t)=300\cdot 1.30^t$

(i.e., there should be a "t" in the exponent. if this is not the case please disregard my answer).

According to the above exponential function, the initial amount 300 grows as (1+0.3)*300=300+0.3*300. In other words it increases by 30% every hour (t).

Your answer choice (A) is likely a candidate, except I am missing "every hour" at the end (again, am assuming this was omitted by mistake)
