In this case, we are given with the expression <span>sin(cos 8θ)/sec 5θ and is asked to evaluate the expression with limit as theta approaches 0. In this case, we just substitute 0 to theta. cos 0 is equal to 1 hence sec 0 is also equal to 1. sin theta is equal to 0.0175. Answer os 0.0175.</span>

Answer:

The answer is 0.01745

Step-by-step explanation:

Given the limit of the trigonometry function

lim θ→0 sin(cos 8θ)/sec 5θ

To evaluate the limit;

Step 1: substitute the value of θ =0 in the trigonometry function given to have;

lim θ→0 sin(cos 8θ)/sec 5θ

= sin(cos8(0))/sec5(0)

= sin(cos0)/sec0

Since cos 0= 1, the function becomes;

sin1/sec0

Step2: write the secant function as a function of cosine function where

Secθ = 1/cosθ

The resulting equation will become;

Sin1/(1/cos0)

Since cos0 = 1, the equation becomes;

Sin1/(1/1)

= sin1

= 0.01745

Katen [24]
-2x+4y=4 Equation 1
x-2y=6 Equation 2
Solving by substitution method.
Isolate x from equation 2.
x=2y+6 
Substitute value of x in equation 1
-2(2y+6)+4y=4
-4y-12+4y=4
-12=4
-16=0
Which is false.

If I paid $205.50 for a phone that was 70% off, then what was the original price of the phone
slega [8]

Answer:

£349.35

Step-by-step explanation:

okay so firstly add the % to 100 = 170

then do 170 divided by 100 and multiply by the total ($205.50)

this would give you $349.35 <----- this is your orignal price (before the sale 70% off)

A researcher is interested in knowing the average height of the men in a village. To the researcher, the population of interest
Anna11 [10]

Answer:

The population mean height of men in the village is 5.78 feet.

The sample mean height of men in the village is 7.8 feet.

Step-by-step explanation:

It is provided that the researcher's interest is in knowing the average height of the men in a village.

To the researcher, the population of interest is the <em><u>men</u></em><em> </em>in the village, the relevant population data are the <em><u>height of men</u></em> in the village, and the population parameter of interest is the <em><u>mean height of men</u></em>.

It is also provided that there are 590 men in the village, and the sum of their heights is 3,410.2 feet.

Compute the average height as follows:

\bar X_{H}=\frac{3410.2}{590}=5.78\ \text{feet}

Thus, the population mean height of men in the village is 5.78 feet.

It is given that the researcher measured the heights of 18 village men and calculated the average to estimate the average height of all the village men.

The sample for his estimation is <em><u>18 men</u></em>, the relevant sample data are the <em><u>heights of the 18 men</u></em>, and the sample statistic is the <em><u>sample mean height</u></em>.

It is also given that the  sum of the heights of the 18 village men is 104.4 feet.

Compute the average height of the 18 men as follows:

\bar x_{H}=\frac{104.4}{18}=7.8\ \text{feet}

Thus, the sample mean height of men in the village is 7.8 feet.
