The square shown has a perimeter of 32 units. The square is rotated about line k. what is the circumfrence of the base

boyakko [2]

The circumference equal to 25 units

<h3>What is perimeter of square?</h3>

The perimeter of square is 4 times the side.

P= 4* side

The perimeter of the square,

4x = P

Now P is = 32 units then,

32 units = 4(x)

x = 8 inches

So, the diameter of the cylinder formed by the rotation of 8 inches

Now, the circumference of the base is

C = 2πr = πD

If r =8 inches

C = π(8 units) = 8π units

C = 8(3.14) = 25.12 units

Hence, the circumference equal to 25 units

A random sample of 56 lithium batteries has a mean life of 645 hours with a population standard deviation of 31 hours. Compute t

bearhunter [10]

Answer: A. (636.9, 653.1)

Step-by-step explanation:

Given : Sample size : n=56

Significance level : $\alpha: 1-0.95=0.05$

Critical value : $z_{0.05}=1.96$

Sample mean : $\overline{x}=645\text{ hours}$

Standard deviation : $\sigma= 31\text{ hours}$

The 95% confidence interval for population mean is given by :-

$\overline{x}\pm z_{\alpha/2}\dfrac{\sigma}{\sqrt{n}}\\\\=645\pm (1.96)\dfrac{31}{\sqrt{56}}\\\\=645\pm8.1\\\\=(636.9, 653.1)$

Hence, 95% confidence interval for population mean is (636.9, 653.1).

What type of transformations have occurred in the function shown below?

Liono4ka [1.6K]

Using shifting concepts, it is found that the correct option is:

Vertical stretch, horizontal shift left, vertical shift up.

The original function is:

$y = \sqrt{x}$

The original function was multiplied by 2, hence there was a <em>vertical stretch</em> by a factor of 2.

$x \rightarrow x + 1$ , hence, there was an horizontal shift left.

2 was added to the function, hence, there was a <em>vertical shift up.</em>
