In the given question we can see that the information,Georgina ran a distance of 3/8 mile in 3 minutes is already provided.
So
In 3 minutes Georgina can run a distance of = 3/8 miles
Then In 1 minute Georgina can run a distance of = 3/(8 * 3) miles
= 3/24 miles
= 1/8 miles.
So it can be said now that in 1 minute the distance that Georgina can cover is 1/8 miles. If required it can be converted to decimal value as well.

First, you would divide the 3/8 by 3 to get how many miles in 1 minute.
3/8 by 3 is the same thing as 3/8 times 1/3. Which equals 1/8.

Answer:

The solution of the given trigonometric equation

$x = \frac{\pi }{6}$

Step-by-step explanation:

<u><em>Step(i):</em></u>-

Given

$cos( 3x - \frac{\pi }{3} ) = \frac{\sqrt{3} }{2}$

$cos( 3x - \frac{\pi }{3} ) = cos (\frac{\pi }{6} )$

$3x - \frac{\pi }{3} = \frac{\pi }{6}$

$3x - \frac{\pi }{3 } + \frac{\pi }{3} = \frac{\pi }{6} + \frac{\pi }{3}$

$3x = \frac{2\pi +\pi }{6} = \frac{3\pi }{6} = \frac{\pi }{2}$

$x = \frac{\pi }{6}$

<u><em>Step(ii)</em></u>:-

The solution of the given trigonometric equation

$x = \frac{\pi }{6}$

<u><em>verification </em></u>:-

$cos( 3x - \frac{\pi }{3} ) = \frac{\sqrt{3} }{2}$

put $x = \frac{\pi }{6}$

$cos( 3(\frac{\pi }{6}) - \frac{\pi }{3} ) = \frac{\sqrt{3} }{2}$

$cos (\frac{\pi }{6} ) = \frac{\sqrt{3} }{2} \\\\\frac{\sqrt{3} }{2} = \frac{\sqrt{3} }{2}$

Both are equal

∴The solution of the given trigonometric equation

$x = \frac{\pi }{6}$

Question 1: Which expression correctly shows 2x^5−54x^2 factored over the integers using the difference of cubes method?

lubasha [3.4K]

Answer:

Question 1: Option C, 2x^2(x - 3)(x^2 + 3x + 9)

Question 2: Options 1, 2, 5

Step-by-step explanation:

Question #3

Step 1: Factor

2x^5 − 54x^2

2x^2(x^3 - 27)

<em>2x^2(x - 3)(x^2 + 3x + 9)</em>

<em />

Answer: Option C, 2x^2(x - 3)(x^2 + 3x + 9)

Question #2

p(x) = 4x^6 + 32x^3

<u>Step 1: Factor</u>

4x^6 + 32x^3

4x^3(x^3 + 8)

<em>4x^3(x + 2)(x^2 - 2x + 4)</em>

<em />

Answer: Options 1, 2, 5

HELP!!! i already found x, can someone please help me find y asap?

tamaranim1 [39]

Answer:

Y = 166

Step-by-step explanation:

The missing angle measure in the small trapezoid is 93 degrees. So to solve for “y” you have to make the expression equal to 93.

y - 73 = 93

y = 166

Hope this helps! Pls give brainliest!
