14.3 - (-4.3). the negative will turn into a plus sign since a minus a negative will be positive. so, 14.3 + 4.3 = 18.6!

The answer is 18.6. The double negative (minus a negative) equals a positive. So you add 14.3 + 4.3 = 18.6

First 100 terms of the following sequence 3 ,7 ,11

Sveta_85 [38]

Given that $a_1 = 3, d = 4$

<u>Find the nth term:
</u>
$a_n = 3 + 4(n - 1)$

$a_n = 3 + 4n - 4$

$a_n = 4n - 1$

<u>Find the 100th term:</u>

$a_{100} = 4(100) - 1 = 399$

<u>Find the Sum:</u>

$\text{Sum} = 100(\dfrac{a_1 + a_{100}}{2} )= 100 (\dfrac{3 + 399}{2}) = 20100$

Please show how to compute these values. Thank you.

alekssr [168]

Answer: ln ( 40) *100

Step-by-step explanation:

Substituting 140 in the equation,

140 = 100 + e^(.01q)

40 = e^(.01q)

Take the natural log of bot hsides

ln ( 40) = .01q

q= ln ( 40 ) * 100

The National Science Organization is monitoring the continuous exponential decline of an insect species due to deforestation. Th

kakasveta [241]

Answer:

$P\geq 26e^{-0.079t}$

$P\geq 2$

Step-by-step explanation:

We are given that there is an exponential decay.

Also, the decrease is of constant rate 7.9% i.e. 0.079 each year.

Since, the initial amount of the species is atleast 26 million.

Thus, the inequality for the corresponding model will be, $P\geq 26e^{-0.079t}$ ,

where t is the time period for the decay and P is the population.

Moreover, is is given that the population cannot be less than 2 million.

So, we get, $P\geq 2$ .

Hence, the inequalities to determine the possible number of insects over time are given by,

$P\geq 26e^{-0.079t}$

$P\geq 2$ .
