Answer:

Foci: ((sqrt5),0),((-sqrt5),0)

Asymptotes: y=((1/2)x), y=((-1/2)x)

Step-by-step explanation:

Same rule with x before y as I mentioned in the other problem to identify the graph.

The ratio pages read to minutes for hang is 5 : 8. Who has the greater ratio of pages read to minutes than hang?

Georgia [21]

Answer:

Option B, C, and D

Step-by-step explanation:

This is the complete question below;

The ratio of pages read to minutes for Hang is 5 : 8. Who has a greater ratio of pages read to minutes than Hang? Select all that apply. A. Kira:2 pages read every 4 minutes B. Joe:6 pages read every 9 minutes C. Quon:5 pages read every 7 minutes D. Lulu:10 pages read every 13 minutes E.

EXPLANATION:

We are given, The ratio of pages read to minutes for Hang as 5 : 8. Which means 5/8= 0.625, then we can say he read 0.625 of a page per minute.

Let us do this for each of the given options;

A. Kira:2 pages read every 4 minutes

Kira's rate= 2/4= 0.5page per minute.

B. Joe:6 pages read every 9 minute

Then Joe's rate = 0.667page per minute.

C. Quon:5 pages read every 7 minute

Quon's rate = 5/7 = 0.7143page per minute.

D. Lulu:10 pages read every 13 minutes

Lulu's rate= 10/13= 0.76923page per minute.

Those that that has a greater ratio of pages read to minutes than Hang are

Joe(0.667page per minute)

Quon( 0.7143page per minute)

and Lulu (0.76923page per minute.)

Because their rate is higher than HANG(0.625 of a page per minute.)

Answer this volume based Question. I will make uh brainliest + 50 points

Harlamova29_29 [7]

Answer:

$\huge{\purple {r= 2\times\sqrt[3]3}}$

$\huge 2\times \sqrt [3]3 = 2.88$

Step-by-step explanation:

For solid iron sphere:
radius (r) = 2 cm (Given)

Formula for $V_{sphere}$ is given as:

$V_{sphere} =\frac{4}{3}\pi r^3$

$\implies V_{sphere} =\frac{4}{3}\pi (2)^3$

$\implies V_{sphere} =\frac{32}{3}\pi \:cm^3$

For cone:
r : h = 3 : 4 (Given)
Let r = 3x & h = 4x

Formula for $V_{cone}$ is given as:

$V_{cone} =\frac{1}{3}\pi r^2h$

$\implies V_{cone} =\frac{1}{3}\pi (3x)^2(4x)$

$\implies V_{cone} =\frac{1}{3}\pi (36x^3)$

$\implies V_{cone} =12\pi x^3\: cm^3$

It is given that: iron sphere is melted and recasted in a solid right circular cone of same volume
$\implies V_{cone} = V_{sphere}$

$\implies 12\cancel{\pi} x^3= \frac{32}{3}\cancel{\pi}$

$\implies 12x^3= \frac{32}{3}$

$\implies x^3= \frac{32}{36}$

$\implies x^3= \frac{8}{9}$

$\implies x= \sqrt[3]{\frac{8}{3^2}}$

$\implies x={\frac{2}{ \sqrt[3]{3^2}}}$

$\because r = 3x$

$\implies r=3\times {\frac{2}{ \sqrt[3]{3^2}}}$

$\implies r=3\times 2(3)^{-\frac{2}{3}}$

$\implies r= 2\times (3)^{1-\frac{2}{3}}$

$\implies r= 2\times (3)^{\frac{1}{3}}$

$\implies \huge{\purple {r= 2\times\sqrt[3]3}}$
Assuming log on both sides, we find:

$log r = log (2\times \sqrt [3]3)$

$log r = log (2\times 3^{\frac{1}{3}})$

$log r = log 2+ log 3^{\frac{1}{3}}$

$log r = log 2+ \frac{1}{3}log 3$

$log r = 0.4600704139$

Taking antilog on both sides, we find:

$antilog(log r )= antilog(0.4600704139)$

$\implies r = 2.8844991406$

$\implies \huge \red{r = 2.88\: cm}$

$\implies 2\times \sqrt [3]3 = 2.88$

In a sample of 7500 new iphones, 18 were found to be defective. at this rate, how many defective iphones would be expected in a

viva [34]

In 7500 iPhones, 18 were found defective.
18 of 7500 is 0.24%
0.24% of iPhones were defective.

Using the information above:
In a sample of 60000 new iPhones, 144 would be found defective.
144 of 60000 is 0.24%

Answer: 144 defective iPhones would be expected in a sample of 60,000.

Hope this helps! Good luck. :-)
