The point (2, 3) is on the terminal side of angle Θ, in standard position. What are the values of sine, cosine, and tangent of Θ

stira [4]

Answer:

sin Ф = 3/√13; cos Ф = 2/√13; and tan Ф = 3/2

Step-by-step explanation:

Let's assume we're limiting ourselves to Quadrant I.

Start with the tangent function. tan Ф = opp / adj.

In this case opp = 3 and adj = 2.

The length of the hypotenuse is found using the Pythagorean Theorem and is √(3² + 2²) = √13.

Then sin Ф = opp / hyp = 3/√13 or 3√13/13

and

cos Ф = adj / hyp = 2/√13 or 2√13/13

and (as before)

tan Ф = opp / adj = 3/2

Find the volume of the figure. Round your answer to the nearest tenth if necessary. Use 3.14 for T.

seraphim [82]

Answer:

$\boxed{ \rm \: Volume_{(Cylinder)} \approx \: 461.6 \: {m}^{3} } \rm (rounded \: to \: nearest \: tenth)$

Step-by-step explanation:

Given dimensions:

Radius of the cylinder = 7 metres
Height of the cylinder = 3 metres

Given value of π :

π = 3.14

To find:

The Volume of the cylinder

Solution:

Here, we'll need to use the formulae of the volume of cylinder,to find it's volume.Its actually like a savior while solving these type of questions.

$\pink{\star}\boxed{\rm \: Volume_{(Cylinder)} = \pi{r} {}^{2} h}\pink{\star}$

where,

π = 3.14
r² = (radius)²
h = height

Plug/substitute them onto the formulae,then simplify it using PEMDAS.

[We'll substitute the value of π later]

$\rm \: Volume_{(Cylinder)} = \pi(7) {}^{2} \times 3$

$\rm \: Volume_{(Cylinder)} = \pi(49)(3)$

$\rm \: Volume_{(Cylinder)} = 147\pi \:$

Now substitute the value of π.

$\rm \: Volume_{(Cylinder)} = 147 \times 3.14$

$\rm \: Volume_{(Cylinder)} = 461.58 \: {m}^{3}$

$\boxed{\rm \: Volume_{(Cylinder)} \approx \: 461.6 \: {m}^{3}} \rm (rounded \: to \: nearest \: tenth) \:$

<u>Hence, we can conclude that:</u>

The volume of the cylinder is approximately

461.6 m³.

Write the expression that is represented by the phrase. The product of a number plus 7 and 3.

tamaranim1 [39]

(x+7)•3
this is because the product means multiplication. and it says "of a number", which is x as we don't know the value, "plus 7" so it's x+7. then multiply that by 3.
