V=(4/3)pir^3
find smaller
V=(4/3)pi8^3
V=(4/3)pi512
V=(2048/3)pi

twice of that
Vbig=2*(2048/3)pi
Vbig=(4096/3)pi
find radius
(4096/3)pi=(4/3)pir^3
divide both sides by pi
(4096/3)=(4/3)r^3
times both sides by 3
4096=4r^3
divide both sides by 4
1024=r^3
cube root both sides
8∛2=r

Answer:

slope of n =⅔

Step-by-step explanation:

The product of the slope of two perpendicular lines(m1•m2) must equal -1.

This means that if you have the slope of one line,find it's negative reciprocal to obtain the slope of the other.

Thus,-1/(-3/2)=⅔

In Nebraska, the mean rain-fed corn yield of harvested fields are normally
NikAS [45]

Answer: 169.2 per acre are produced if a field is in the top 25%.

Step-by-step explanation:

Given:  The mean rain-fed corn yield of harvested fields are normally  distributed, produce 147.2 bushels per acre with a standard deviation of 33 bushels per acre.

Let X denote the mean rain-fed corn yield of harvested fields.

Let x denotes the number of bushels per acre are produced if a field is in the top 25%.

Top 25% on a density curve means , (100-25%)i.e. 75% area lies below x.

I.e.

P(X.

Z-score for p-value of 0.75 (one tailed)=0.67 [By z-table]

Then, \dfrac{x-147.2}{33}=0.6744

\Rightarrow\ {x-147.2}=33\times0.67\\\\\Rightarrow\ {x-147.2}=22.11\\\\\Rightarrow\ {x}=22.11+147.2=169.31

Here approx value is 169.2 (from options).

So, 169.2 per acre are produced if a field is in the top 25%.

What is 9/3 equal to?
maria [59]

3 wholes.

If you have a pie and you cut it into 3 equal slices, you have 3/3 because the pie is in 3s but you have the whole thing.

Now imagine buying two more pies and doing the same thing.

You have 9 slices, but only 3 pies.

3 wholes.

A line intersects the points (-5,1) and (-2,7). m=2 Write an equation in point slope form using the point (-5,1) y-[?] = ___(x-_
zalisa [80]

(\stackrel{x_1}{-5}~,~\stackrel{y_1}{1})\qquad (\stackrel{x_2}{-2}~,~\stackrel{y_2}{7}) \\\\\\ \stackrel{slope}{m}\implies \cfrac{\stackrel{rise} {\stackrel{y_2}{7}-\stackrel{y1}{1}}}{\underset{run} {\underset{x_2}{-2}-\underset{x_1}{(-5)}}} \implies \cfrac{7 -1}{-2 +5}\implies \cfrac{6}{3}\implies 2

\begin{array}{|c|ll} \cline{1-1} \textit{point-slope form}\\ \cline{1-1} \\ y-y_1=m(x-x_1) \\\\ \cline{1-1} \end{array}\implies y-\stackrel{y_1}{1}=\stackrel{m}{2}(x-\stackrel{x_1}{(-5)})\implies y-1=2(x+5)
