Find the value of sin100.sin120.sin140.sin160

NARA [144]

The value of $sin100.sin120.sin140.sin160$ is $0.1875$

Step-by-step explanation:

To find the value of $sin100.sin120.sin140.sin160$ , let us find the value of each angle.

The value of $sin100=0.9848$

The value of $sin120=\frac{\sqrt{3} }{2}$

The value of $sin140=0.6428$

The value of $sin160=0.3420$

Substituting the values of sin, we get,

$sin100.sin120.sin140.sin160=0.9848*\frac{\sqrt{3} }{2} *0.6428*0.3420$

Multiplying the values of sin, we get,

$sin100.sin120.sin140.sin160=0.1875$

Thus, the value of $sin100.sin120.sin140.sin160$ is $0.1875$

The population of a town can be modeled by the regression equation y = 20,000(1.03x). Which is the best prediction for the popul

bixtya [17]

Answer:

The best prediction for the population in year 25 is $41,876\ people$

Step-by-step explanation:

we have a exponential function of the form

$y=a(b^{x})$

where

a is the initial value

b is the base

In this problem

$a=20,000\ people$

$b=1.03$

$b=1+r$

$r=b-1=1.03-1=0.03$

$r=3\%$

so

$y=20,000(1.03^{x})$

For $x=25\ years$

substitute

$y=20,000(1.03^{25})$

$y=41,875.56\ people$

Round up

$y=41,876\ people$

the chef is making 10.5 batches of dinner rolls. For each batch, he kneaded dough for 0.7 and let the dough rest for 1.6 hours.

Sergeeva-Olga [200]

Answer: 2.7 hours

Step-by-step explanation:

Hi, to answer this question we simply have to calculate the amount of time that takes making one batch of dinner rolls, by adding the individual times of, kneading, resting and baking.

Mathematically speaking

0.7 hours +1.6 hours +0.4 hours = 2.7 hours

It takes 2.7 hours to make each batch of dinner rolls.

You have just timed a person doing a hair cut for the first time. It took 50 minutes. What unit improvement factor learning curv

Sladkaya [172]

Answer: C. 70 percent

Step-by-step explanation:

Given, Time for the first unit = 50 minutes

Time for the second unit = 35 minutes

The unit improvement factor learning curve = (The time for the second unit) ÷ (time for the first unit) x 100.

So, The unit improvement factor learning curve = 35÷ 50 × 100 = 70 percent.

Hence, the correct option is "C. 70 percent".
