Since we have given that

Surface area of sphere = 576 pi cm. sq.

As we know the formula,

Surface area of sphere is given by

So, the volume of a sphere would be

Hence, the required volume is 7241.14 cm³.

Given g(x)=3x+6 on what interval is the function negative

iris [78.8K]

Step-by-step explanation:

A number that is negative is less than 0, so

$3x + 6 < 0$

$3x < - 6$

$x < - 2$

So this function is negative, when x is less than -2

Answer:

standard error of the mean = 1.6960

Step-by-step explanation:

Given -

Mean $(\overline{X})$ = 53 minutes

Standard deviation ( s ) = 53.9 minutes

n = 1010

standard error of the mean =

$\sigma _{\overline{X}}$ = $\frac{s}{\sqrt{n}}$

= $\frac{53.9}{\sqrt{1010}}$

= 1.6960

What is - 4i ^ 19, simplify

german

Answer:

$"i"$

Step-by-step explanation:

$i =\sqrt{-1} \\i^{2}= -1\\\\i^{3}= -i\\\\i^{4}= 1\\\\i^{5}= i\\$

the cycle repeats every 4

19/4 = 4.75

16 is divisible by 4 plus three more

thus $i^{19} = -i$ but you problem has a minus in front so "i"
