Answer:

The slope from point O to point A is 3 times the slope of the line from point A to point B.

Step-by-step explanation:

The slope of the entire line is 1. The slope from point A to point B is also 1. 1 multiplied by 3 is still 1, which means that the slope from point O to point A is also 1.

Which shape has the greatest volume
Tresset [83]

Hey mate ,

In this particular question we have to find<u> the volume of given objects and compare to find which has the greatest volume. </u>

<u>Lets </u><u>Solve</u><u> </u><u>,</u><u> </u>

  • Cone =

Volume of cone :- 1/3πr²h

<u>putting</u><u> the</u><u> known</u><u> values</u><u> </u><u>,</u><u> </u>

Volume = 1/3×3.14×5²×7 cubic ft.

<u>Volume</u><u> </u><u>:</u><u>-</u><u> </u><u>1</u><u>8</u><u>3</u><u>.</u><u>1</u><u> </u><u>cubic </u><u>ft.</u>

  • Sphere

Volume of Sphere = 4/3πr³

<u>putting</u><u> the</u><u> known</u><u> values</u><u> </u><u>,</u><u> </u>

Volume = 4/3×3.14×5³ cubic ft.

<u>Volume</u><u> </u><u>=</u><u> </u><u>5</u><u>2</u><u>3</u><u>.</u><u>3</u><u>3</u><u> </u><u>cubic </u><u>ft.</u>

  • Cylinder

Volume of Cylinder = πr²h

<u>putting</u><u> the</u><u> known</u><u> values</u><u> </u><u>,</u><u> </u>

Volume = 3.14×5²×7 cubic ft.

<u>Volume</u><u> </u><u>=</u><u> </u><u>5</u><u>4</u><u>9</u><u>.</u><u>5</u><u> </u><u>cubic</u><u> </u><u>ft.</u>

  • Hemisphere

Volume of hemisphere = 2/3πr³

<u>Putting</u><u> the</u><u> known</u><u> values</u><u> </u><u>,</u><u> </u>

Volume = 2/3×3.14×5³ cubic ft

<u>Volume</u><u> </u><u>=</u><u> </u><u>2</u><u>6</u><u>1</u><u>.</u><u>6</u><u>6</u><u> </u><u>cubic</u><u> ft</u><u>.</u><u> </u>

Comparing the volume of each object , we can find that the <u>Cylinder</u> has the greatest volume

Tasya [4]

Answer:

<h2>x = 5</h2>

Step-by-step explanation:

3x+5=20\qquad\text{subtract 5 from both sides}\\\\3x+5-5=20-5\\\\3x=15\qquad\text{divide both sides by 3}\\\\\dfrac{3x}{3}=\dfrac{15}{3}\\\\x=5

Sin∅=√3-1/2 find approximate value of sec∅(sec∅+tan∅)/1+tan²∅​
Neko [114]

Answer:

The approximate value of f(\theta) = \frac{\sec \theta \cdot (\sec \theta+\tan \theta)}{1+\tan^{2}\theta} is 1.366.

Step-by-step explanation:

Let f(\theta) = \frac{\sec \theta \cdot (\sec \theta+\tan \theta)}{1+\tan^{2}\theta}, we proceed to simplify the formula until a form based exclusively in sines and cosines is found. From Trigonometry, we shall use the following identities:

\sec \theta = \frac{1}{\cos \theta} (1)

\tan\theta = \frac{\sin\theta}{\cos \theta} (2)

\cos^{2}+\sin^{2} = 1 (3)

Then, we simplify the given formula:

f(\theta) = \frac{\left(\frac{1}{\cos \theta} \right)\cdot \left(\frac{1}{\cos \theta}+\frac{\sin \theta}{\cos \theta}\right) }{1+\frac{\sin^{2}\theta}{\cos^{2}\theta} }

f(\theta) = \frac{\left(\frac{1}{\cos^{2} \theta} \right)\cdot (1+\sin \theta)}{\frac{\sin^{2}\theta + \cos^2{\theta}}{\cos^{2}\theta} }

f(\theta) = \frac{\left(\frac{1}{\cos^{2}\theta}\right)\cdot (1+\sin \theta)}{\frac{1}{\cos^{2}\theta} }

f(\theta) = 1+\sin \theta

If we know that \sin \theta =\frac{\sqrt{3}-1}{2}, then the approximate value of the given function is:

f(\theta) = 1 +\frac{\sqrt{3}-1}{2}

f(\theta) = \frac{\sqrt{3}+1}{2}

f(\theta) \approx 1.366
