What is the sum of the polynomials?<br> (7x^3– 4x^2) + (2x^3 +3x)

DaniilM [7]

Answer:

sum of the polynomials is $9 x^{3} - 4 x^{2} +3x$

Step-by-step explanation:

Given polynomial is (7 x^3– 4 x^2) + (2 x^3 +3 x)

adding x^3 terms, now we get

$(7+2)x^3-4 x^2+3 x$

$9 x^{3} - 4 x^2 +3 x$

Therefore the sum of given polynomial is

$9 x^3-4 x^2+3 x$

If tanA+cotA=2 then find the value of cosA

aniked [119]

Answer:

cos A=

$\frac{1}{ \sqrt{2} }$

Step-by-step explanation:

We know,

cotA=

$\frac{1}{ \tan(a) }$

Substituting the value of cot A in the given equation, we get

$\tan( a) + \frac{1}{ \tan(a) } = 2$

$\frac{{ \tan }^{2} a + 1}{ \: \tan(a) } = 2$

${ \tan }^{2 \: } a \: + 1 = 2 tan \: a$

${ \tan }^{2} a - 2 \tan \: a + 1 = 0$

$( \tan \: a - 1) {}^{2 } = 0$

$\tan \: a - 1 = \sqrt{0}$

$\tan \: a = 1$

$\tan \: a \: = \tan \: 45$

$a = 45$

$\cos \: a = \cos \: 45$

$\cos \: a = \frac{1}{ \sqrt{2} }$

A cone has a volume of 6 cubic inches. What is the volume of a cylinder that the cone fits exactly inside of?

solmaris [256]

Formula for calculating volume of a cone is:

V = B*H/3

Formula for calculating volume of cylinder is:
V2 = B2*H2

because our cone fits exactly inside cylinder that means that their bases are the same and heights are the same. From this we can conclude (observing formulas for each volume) that cone has 3x less volume than our cylinder.

Cylinder volume is 6*3 = 18 in^3
