The number of the trees that will be left after 10 years will be 2.3 billions.

A rate of change is negative when the output decreases as the input increases or when the output increases as the input decreases.

Given that, the number of trees in a rainforest decreases each month by 0.5%. The forest currently has 2.5 billion trees.

The expression will be:

A = P(1-r)ⁿ

A = final amount

P = initial amount

r = rate

n = time

Therefore,

A = 2500000000(1-00.5)¹⁰

A = 2500000000(0.995)¹⁰

A = 2300000000

Hence, the number of the trees that will be left after 10 years will be 2.3 billions.

The probability that the numbers on the broken calculators are at least 16 will be 0.9997.

Its basic premise is that something will almost certainly happen. The percentage of favorable events to the total number of occurrences.

There are 30 calculators numbered 1-30 in a case. If 4 of the calculators are broken.

Then the probability that the numbers on the broken calculators are at least 16 will be

Number of ways to get a sum less than 16 = 1234, 1235, 1236, 1237, 1238, 1239, 2345, 2346 = 8

Probability = 1 – 8 / (³⁰C₄) =  1 – 8/27405 = 0.99970808246

y=5+5/1

5/1= rise/run

Answer:

Yes

Step-by-step explanation:

when you go over one (x), you go up five (y), on the chart. That's the definition of a slope - rise/run.

Explanation: In this expression, +2w, +4w, and +8w are called terms and the numbers in front of the variables, +2, +4, and +8 are called coefficients.

Because the variables are identical,

the three terms in this problem are called like terms.

They can be added together by adding their coefficients.

Since 2 + 4 + 8 is 14, 2w + 4w + 8w is 14w.

Apply l'Hopital's rule:

[tex]\displaystyle\lim_{x\to\pi}\frac{\displaystyle\int_\pi^x (1+\tan(t))\,\mathrm dt}{\pi\sin(x)}=\lim_{x\to\pi}\frac{1+\tan(x)}{\pi\cos(x)}=\frac{1+\tan(\pi)}{\pi\cos(\pi)}=\boxed{-\frac1\pi}[/tex]

where

[tex]\displaystyle\frac{\mathrm d}{\mathrm dx}\left[\int_\pi^x(1+\tan(t))\,\mathrm dt\right]=1+\tan(x)[/tex]

follows from the fundamental theorem of calculus.

Step-by-step explanation:

Answer:

[tex]\mathrm{A.} \: \frac{5}{14}\cdot \frac{4}{13}\\[/tex]

Step-by-step explanation:

There are 14 marbles in total, of which 5 of them are red. Therefore, the probability that the first marble she chooses is red is [tex]\frac{5}{14}[/tex].

Since she does not replace the marble, there are now 13 marbles in total, of which 4 are red (she drew one of the red marbles on her first draw). Therefore the probability of her drawing a red marble on her second draw is [tex]\frac{4}{13}[/tex], assuming she draws a red marble on the first draw.

Thus, the probability she draws a red marble on both draws is [tex]\fbox{$\mathrm{A.} \: \frac{5}{14}\cdot \frac{4}{13}$}[/tex].

Step-by-step explanation:

f (x) = 2x3 + 3x2 + 18x + 27

Set 2x^3 + 3x^2 + 18x + 27 equal to 0.

2x^3 + 3x^2 + 18x + 27 = 0

Solve for x.

Factor the left side of the equation.

Factor out the greatest common factor from each group.

x^2 (2x + 3) + 9 (2x + 3) = 0

Factor the polynomial by factoring out the greatest common factor, 2x + 3. (2x + 3) (x^2 + 9) = 0

If any individual factor on the left side of the equation is equal to 0, the entire expression will be equal to 0.

2x + 3 = 0

x^2 + 9 = 0

Set 2x + 3 equal to 0 and solve for x.

Set 2x + 3 equal to 0. 2x + 3 = 0

Solve 2x + 3 = 0 for x. Tap for more steps...  

3 x = − 2

Set x2 + 9 equal to 0 and solve for x.

Set x2 + 9 equal to 0. x2 + 9 = 0

Solve x2 + 9 = 0 for x.

x = 3i, −3i

The final solution is all the values that make (2x + 3) (x2 + 9) = 0 true.

Answer:

The best course grade your friend can earn is 0.867 = 86.7%.

The minimum score would your friend would need on the final to earn a 75% for the course is of 0.61 = 61%.

Step-by-step explanation:

This is a weighed average problem, in which we multiply each grade by its weight.

We have that:

In 70% of the course, the friend has a grade of 81%.

In the other 30%, he will have x.

What is the best course grade your friend can earn?

This will happen if he earns 100% = 1 on the final test. So

[tex]G = 0.7*0.81 + 0.3*1 = 0.867[/tex]

The best course grade your friend can earn is 0.867 = 86.7%.

What is the minimum score would your friend would need on the final to earn a 75% for the course?

This is x, when the grade is 0.75. So

[tex]0.75 = 0.7*0.81 + 0.3x[/tex]

[tex]0.3x = 0.75 - 0.7*0.81[/tex]

[tex]x = \frac{(0.75 - 0.7*0.81)}{0.3}[/tex]

[tex]x = 0.61[/tex]

The minimum score would your friend would need on the final to earn a 75% for the course is of 0.61 = 61%.
