What is the product of a+3 and −2a2+15a+6b2?

Lady bird [3.3K]

Answer:

c. 2a3+9a2+45a+6ab2+18b2

Step-by-step explanation:

(a+3) + (−2a2+15a+6b2)

Using distributed p. with and a and 3

a(−2a2) + a(15a) +a(6b2) and 3(−2a2) + 3(15a) + 3(6b2)

= -−2a3 + 15a2 + 6ab2 = -6a2 + 45a + 18b2

Now add like terms and put in standard form.

15a2+(-6a2) = 9a2

And equals

-2a3 + 9a2+45a+6ab2+18b2

Trust me I took the test and got 100%

In a large population, 57 % of the people have been vaccinated. If 3 people are randomly selected, what is the probability that

ollegr [7]

Answer:0.92

Step-by-step explanation:

Given

$57\%$ of Population is vaccinated

So, Probability of a person being vaccinated is $P=0.57$

and simultaneously , probability of not vaccinated is $1-P$

$=1-0.57=0.43$

Now, Probability that atleast one of them has been vaccinated is given by

$=1-P(\text{None of them is vaccinated})$

$=1-0.43\times 0.43\times 0.43$

$=1-0.0795$

$=0.92$

Y=25000(1-0.63)^2<br> Find the decay rate.

Anestetic [448]

If I'm not mistaken.. the half-life should be 40,750 years.. so

y = 40,750

I got this by multiplying 25,000 by 1.63 and then if you divide by 2.. you get

20,375.. so one of those should be correct
