There are 21 people in the crew.

Step-by-step explanation:

Given,

Number of men in the crew = 14

Percent of men = $66\frac{2}{3}=\frac{200}{3}$ %

Let,

x be the number of people in crew.

According to given statement;

$\frac{200}{3}\% \ of\ x=14\\\\\frac{200}{3*100}x=14\\\\\frac{200}{300}x=14$

Multiplying both sides by $\frac{300}{200}$

$\frac{300}{200}*\frac{200}{300}x=14*\frac{300}{200}\\x=7*\frac{300}{100}\\x=7*3\\x=21$

There are 21 people in the crew.

The as x approaches 0 of tan^2x/x

uysha [10]

L=Lim tan(x)^2/x x->0

Since both numerator and denominator evaluate to zero, we could apply l'Hôpital rule by taking derivatives.

d(tan^2(x))/dx=2tan(x).d(tan(x))/dx = 2tan(x)sec^2(x)

d(x)/dx = 1

L=2tan(x)sec^2(x)/1 x->0

= (2(0)/1^2)/1

=0/1

Another way using series,

We know that tan(x) = x+x^3/3+2x^5/15+.....

then tan^2(x), using binomial expansion gives

x^2+2*x^4/3+.... (we only need two terms)

and again apply l'Hôpital's rule, we have

L=d(x^2+2x^4/3+...)/d(x) = (2x+8x^3/3+...)/1

=0 as x->0

A recursive rule for an arithmetic sequence is a1=4;an=an−1−3 . What is the explicit rule for this sequence? Enter your answer i

Westkost [7]

Answer:

The explicit rule for the arithmetic sequence is given by:

$a_n = a_1+(n-1)d$ ......[1]

where,

$a_1$ is the first term

n is the number of terms and

d is the common difference for two consecutive terms.

As per the statement:

A recursive rule for an arithmetic sequence is:

$a_1 = 4$

$a_n = a_{n-1}-3$

The recursive formula for the arithmetic sequence is given by:

$a_n = a_{n-1}+d$

then;

On comparing we get;

d = -3

Substitute the given values in [1] we have;

$a_n = 4+(n-1)(-3)$

⇒ $a_n = 4 -3n+3 = 7-3n$

Therefore, the explicit rule for this sequence is, $a_n = 7 -3n$

A 16-cup container of laundry detergent costs $13.60. What is the price per quart?

777dan777 [17]

Answer:

$0.21

Step-by-step explanation:

So, first let's find the cost of a single cup.

16/13.60 = 1/0.85

Now, we know that each cup is approximately $0.85. Next, we must convert cups into quarts. 1 cup = 0.25 quarts.

1/0.85 = 0.25/0.21

Julio's goal is to type an average of 50 words per minute on his five typing exams. His scores on the first four exams were 46,4

Svetllana [295]

Answer is 56 because on his 3rd exam he got 57 word per minute, since he got 57 he can take out 7 of those words and he would still have 50. Remember the extra 7 words we have. Then you would calculate how many more words he needs to get to fifty on his other exams which are 4,6,and 3. Add these 3 and you get 13. Remember we still have that extra 7. We pick 56 with the extra 7 it would be 63. You can take out 13 words to fill in the other exams and u would still be left with 50.
Therefor your answer is 56.
