Answer:

The domain of x for the given function, y = $\sqrt{x}$ + 4, in interval notation is [ 0, $\infty$ )

Step-by-step explanation:

The given function is y = $\sqrt{x}$ + 4

We cannot have square root of a negative number.

The minimum of x can be only 0.

The maximum of x can tend to $+\infty$ .

Therefore the domain of x in interval notation is [ 0, $\infty$ )

What is the equation in slope-intercept form of a line that passes through the point (4, 5) and has a slope of 12?

victus00 [196]

Answer:

y= 12x -43

Step-by-step explanation:

y-5 = 12(x-4)

y-5= 12x-48

+5 +5

y= 12x- 43

What is the volume of a hollow ball whose other radius is 200m and inner radius of 100m? What is the mass if it is iron?

kati45 [8]

Solution :

Volume of ball = Volume of outer ball - Volume of inner ball

$V = \dfrac{4\pi R^3}{3} - \dfrac{4 \pi r^3}{3}\\\\V = \dfrac{4\pi}{3}( R^3 - r^3 )\\\\V = \dfrac{4\pi}{3}( 200^3 - 100^3 )\\\\V = \dfrac{4\pi}{3}(2^3 - 1^3) \times 10^6\\\\V = 2.93 \times 10^7 \ m^3$

Now, density of iron is, d = 7300 kg/m³.

So, mass of iron ball is :

$m = d\times V\\\\m = 7300\times 2.93 \times 10^7 \ kg\\\\m = 2.14 \times 10^{11}\ kg$

Hence, this is the required solution.

Suppose you have a set of data points with a correlation of 0.85. What is the variance? A. Variance = √ r = 0.92195 B. Variance

TiliK225 [7]

Answer:

B. Variance = r2 = 0.7225

Step-by-step explanation:

Given the correlation coefficient, variance is obtained by squaring the correlation coefficient to obtain what is also know as coefficient of determination. Gives information on the predictive power of the model
