For which intervals is the function decreasing?
lilavasa [31]

Answer:

The function is decreasing in the following intervals

A. (0, 1)

C. (2, pi)

Step-by-step explanation:

To answer this question, imagine that you draw lines of slope m parallel to the function shown at each point.

-If the slope of this line parallel to the function is negative for those points then the function is decreasing.

-If the slope of this line parallel to the function is positive for those points then the function is increasing.

Observe in the lines drawn in the attached image. You can see that they have slope less than zero in the following interval:

(0, 1) U (2, pi)

Therefore the correct option is:

A. (0, 1)

C. (2, pi)

A consumer group claims that the average annual consumption of high fructose corn syrup by a person in the U.S. is 48.8 pounds.
LenaWriter [7]

Answer:

6.7159

Step-by-step explanation:

\mu=48.8\\n=35\\\bar{x}=53.8\\\sigma=4.4\\\alpha=1\%=0.01

Null and alternative hypothesis :

H_0:\mu=48.8\\H_a:\mu>48.8

Test statistic,

t=\frac{\bar{x}-\mu}{\frac{\sigma}{\sqrt{n}}}

\Rightarrow t=\frac{53.8-48.8}{\frac{4.4}{\sqrt{35}}}

\Rightarrow t=\frac{5\times 5.91}{4.4}

\Rightarrow t=6.715

Test statistic t=6.715

P-value =P(t>6.715)

P- value =0.0001  by the p- table

Significance level 0.01

         p-value

  We reject H_0

A beehive has a population of 300. The population is increasing at a rate of 10% per year. How can you write an exponential grow
kobusy [5.1K]

Answer:

300 × (1 + 0.10)^n

Step-by-step explanation:

The computation is shown below:

Given that

The population is 300

And, the population would be increased at a rate of 10% each year

So, the exponential growth function to calculate the daily growth rate is

= 300 × (1 + 0.10)^n

Here n represent the number of years or the time period

So, the above show the exponential growth function
