asambeis [7]3 years ago
4 0

Answer:

we have the expression as;

1/sin u cos u

Step-by-step explanation:

tan u = sin u/cos u

cot u = cos u/sin u

Thus;

sin u/cos u + cos u/sin u

The lcm is sin u cos u

Thus, we have that;

(sin^2 u + cos^2 u)/sin u cos u

But ; sin^2 u + cos^2 u = 1

so we have ;

1/sin u cos u

sertanlavr [38]

<u>Answer: </u>

Expression x + 2my + z represents cost of order where x, y, z are cost of small , medium and large drinks (in dollars) respectively.

<u>Solution: </u>

Given that  

Juan’s family ordered a small drink and m medium drinks.

Alex family ordered m medium drinks and a large drink.

Need to write an algebraic expression which shows total cost of both order in dollars.

Let’s assume cost of one small drink = x

And assume cost of one medium drink = y

And assume cost of one large drink = z

So now cost of order of Juan’s family is equal to cost of 1 small drink + cost of m medium drinks = 1 \times x + m \times y

= x + my

And cost of order of Alex family is equal to cost of m medium drinks + cost of one large drink

= m x y + 1 x z

=my + z

So total cost of both order in dollars = x + my + my + z = x + 2my + z

Hence expression x + 2my + z represents cost of order where x , y , z are cost of small , medium and large drinks (in dollars) respectively.

​Which values are solutions to the inequality? ​ ​5r≤6r−8​ ​ Select each correct answer. r = 7 r = 8 r = 9 r = 10
Ratling [72]

Answer:

r = 8,9,10

Step-by-step explanation:

The given inequality is :

​5r≤6r−8​  ...(1)

We need to find the value of r.

Subtracting 5r to both sides of the inequality .

​5r-5r≤6r-5r−8

0≤r−8

r ≥ 8

Hence, the values of r are 8,9,10.

sp2606 [1]

Answer: p-value \approx 0.01

Step-by-step explanation:

Hypothesis testing

\\\left\{\begin{matrix}H_0 : \mu_0 =0\\ H_1: \mu_0 \neq 0\end{matrix}\right.\\

For this problem, we need to use the t-student distribution to  make inference about the data. We calculate the t-statistics as below:

\bar{X} = 20\:\mu m\\S.E. = 60\:\mu m\\n=82\\t_{stat} = \frac{\bar{X}-\mu_0}{S.E/\sqrt{n}}=\frac{20-0}{60/\sqrt{82}}=3.0185

Using a t-statistics table, or using the function TDIST in Microsoft Excel with t_{stat} = 3.0185,\: df (degree\: of\: freedom) = 14 - 1 = 13 with two-tailed distribution, we obtain p-value \approx 0.01.
