Answer» Step-by-step explanation: Each of these objects is an example of a perfect CUBE. A cube is a unique 3-dimensional shape that has squares for all six of its sides. So, how do we find out how big a cube is? The answer to this question utilizes the OBJECT's volume. The volume of any cube can be DETERMINED as the amount of space the cube takes up or as the amount of space INSIDE of the cube. Which DEFINITION applies to our examples? The volume of children's blocks or dice would both be described as the amount of space the cube takes up. hope it help u mark as brainlist

18060.	plz help me to factorise this polynomial.I will follow u mark as brainliest
Answer» Step-by-step explanation: a2" was replaced by "a^2". 1 more similar replacement(s). (((5 • (a3)) + 11a2) + 4a) - 2 ((5a3 + 11a2) + 4a) - 2 5a3+11a2+4a-2 is not a perfect cube The FACTOR Theorem states that if P/Q is root of a polynomial then this polynomial can be DIVIDED by qx-p Note that q and p originate from P/Q reduced to its lowest terms In our case this means that 5a3+11a2+4a-2 can be divided with a+1 Polynomial Long Division Dividing : 5a3+11a2+4a-2 ("DIVIDEND") By : a+1 ("Divisor") dividend 5a3 + 11a2 + 4a - 2 - divisor 5a2 5a3 + 5a2 remainder 6a2 + 4a - 2 - divisor * 6a1 6a2 + 6a remainder - 2a - 2 - divisor * -2a0 - 2a - 2 remainder 0 Quotient : 5a2+6a-2 Remainder: 0 (5a2 + 6a - 2) • (a + 1) is ur answer

18060.

plz help me to factorise this polynomial.I will follow u mark as brainliest

Answer»

Step-by-step explanation:

a2" was replaced by "a^2". 1 more similar replacement(s).

(((5 • (a3)) + 11a2) + 4a) - 2

((5a3 + 11a2) + 4a) - 2

5a3+11a2+4a-2 is not a perfect cube

The FACTOR Theorem states that if P/Q is root of a polynomial then this polynomial can be DIVIDED by q*x-p Note that q and p originate from P/Q reduced to its lowest terms

In our case this means that

5a3+11a2+4a-2

can be divided with a+1

Polynomial Long Division

Dividing : 5a3+11a2+4a-2

("DIVIDEND")

By : a+1 ("Divisor")

dividend 5a3 + 11a2 + 4a - 2

- divisor * 5a2 5a3 + 5a2

remainder 6a2 + 4a - 2

- divisor * 6a1 6a2 + 6a

remainder - 2a - 2

- divisor * -2a0 - 2a - 2

remainder 0

Quotient : 5a2+6a-2 Remainder: 0

(5a2 + 6a - 2) • (a + 1) is ur answer

18061.

If∆abc~∆pqr and m angle a=45°, m angle q=87°, then m angle c= -----.

Answer»

$given$

angle A = 45°

angle B = 87°

$to \: find$

find angle C

$solution$

As we KNOW SUM of all angle of a TRIANGLE is 360°.

therefore,

a+b+c = 360°

45°+87°+c = 360°

132°+c = 360°

c = 360°-132°

c = 228°

Answer» Answer: 1.1 Factoring y2-6y-40 The first term is, y2 its COEFFICIENT is 1 . The middle term is, -6y its coefficient is -6 . The last term, "the constant", is -40 Step-1 : Multiply the coefficient of the first term by the constant 1 • -40 = -40 Step-2 : Find two factors of -40 WHOSE sum equals the coefficient of the middle term, which is -6 . -40 + 1 = -39 -20 + 2 = -18 -10 + 4 = -6 That's it Step-3 : REWRITE the polynomial splitting the middle term using the two factors found in step 2 above, -10 and 4 y2 - 10y + 4y - 40 Step-4 : Add up the first 2 terms, pulling out like factors : y • (y-10) Add up the last 2 terms, pulling out common factors : 4 • (y-10) Step-5 : Add up the four terms of step 4 : (y+4) • (y-10) Which is the desired factorization Equation at the end of step 1 : (y + 4) • (y - 10) = 0

18064.

Factorise Y²+40Y+39

Answer»

Answer:

1.1 Factoring y2-6y-40

The first term is, y2 its COEFFICIENT is 1 .

The middle term is, -6y its coefficient is -6 .

The last term, "the constant", is -40

Step-1 : Multiply the coefficient of the first term by the constant 1 • -40 = -40

Step-2 : Find two factors of -40 WHOSE sum equals the coefficient of the middle term, which is -6 .

-40 + 1 = -39

-20 + 2 = -18

-10 + 4 = -6 That's it

Step-3 : REWRITE the polynomial splitting the middle term using the two factors found in step 2 above, -10 and 4

y2 - 10y + 4y - 40

Step-4 : Add up the first 2 terms, pulling out like factors :

y • (y-10)

Add up the last 2 terms, pulling out common factors :

4 • (y-10)

Step-5 : Add up the four terms of step 4 :

(y+4) • (y-10)

Which is the desired factorization

Equation at the end of step

1

:

(y + 4) • (y - 10) = 0

18073.	Ifcos theta + sec theta= 2.find cos 70 + sec 70=?
Answer» Cos theta+sec theta =2 => cos ^2 theta +1 = 2 cos theta => cos^2 theta -2 cos theta +1=0 Solving the above quadratic equation in cos theta,we get cos theta =1 =>theta =cos INVERSE (1) =>theta=2 n pi Now we need to FIND the value of cos 100 theta+sec 100 theta Substitute the value of theta as theta=2 n pi: =>cos 100 theta + sec 100 theta = cos 100 (2 n pi) + sec 100 (2 n pi) =cos 2 (100n pi) + sec 2 (100n pi) Let 100n=k , some variable =>cos 100 theta + sec 100 theta = cos (2 k pi) + sec (2 k pi) = 1 + 1 = 2

18073.

Ifcos theta + sec theta= 2.find cos 70 + sec 70=?

Answer»

Cos theta+sec theta =2

=> cos ^2 theta +1 = 2 cos theta

=> cos^2 theta -2 cos theta +1=0

Solving the above quadratic equation in cos theta,we get

cos theta =1

=>theta =cos INVERSE (1)

=>theta=2 n pi

Now we need to FIND the value of

cos 100 theta+sec 100 theta

Substitute the value of theta as theta=2 n pi:

=>cos 100 theta + sec 100 theta = cos 100 (2 n pi) + sec 100 (2 n pi)

=cos 2 (100n pi) + sec 2 (100n pi)

Let 100n=k , some variable

=>cos 100 theta + sec 100 theta = cos (2 k pi) + sec (2 k pi) = 1 + 1 = 2

Answer:

3:4

Step-by-step explanation:

Given

Height of FIRST cylinder = 15

Height of second cylinder = 20

To find

Ratio of there area

$\sf \boxed{ \sf \: volume \: of \: cylinder = \pi {r}^{2} h}$

$\sf \: volume \: of \: first \: cylinder = \pi {r}^{2} 15$

$\sf volume \: of \: second \: cylinder = \pi {r}^{2} 20$

As we KNOW that area and base are same , we need not do any kinda further calculations by plugging extra number.

Now , arranging the obtained value in ratio form :

$\implies \huge \frac{ {\cancel{\pi {{r}^{2}}}}15 }{ \cancel{\pi {r}^{2} }20}$

$\sf \implies \: \frac{15}{20} = \frac{3}{4}$

Ratio = 3:4

What you need to know ?

Volume : 3-dimensional SPACE enclosed by a boundary or occupied by an object.

Ratio is COMPARISON between two known sets of values.

18090.	What is abscissa of (5,-8)
Answer» Answer : 5 Explanation: The X - coordinate of any point A(x,y) is CALLED the anscissa of the given point A . Here , the x - coordinate was 5 , so the anscissa of (5, -8 ) is 5 . The y - coordinate of any point A(x , y) is called its ordinate . If it was to ASK the ordinate of (5, -8 ) , the ordinate would be -8 . There are four quadrants in a graph : 1) (x,x) 2) (-x , +y) 3) (-x , -y) 4) (x , - y) This point (5 , -8) belongs to the fourth quadrant of the graph containing positive anscissa and negetive ordinate . The geometry of graphs and coordinate points is termed as coordinate geometry .

What is abscissa of (5,-8)

Answer»

Answer :

5

Explanation:

The X - coordinate of any point A(x,y) is CALLED the anscissa of the given point A . Here , the x - coordinate was 5 , so the anscissa of (5, -8 ) is 5 .

The y - coordinate of any point A(x , y) is called its ordinate . If it was to ASK the ordinate of (5, -8 ) , the ordinate would be -8 .

There are four quadrants in a graph :

1) (x,x)

2) (-x , +y)

3) (-x , -y)

4) (x , - y)

This point (5 , -8) belongs to the fourth quadrant of the graph containing positive anscissa and negetive ordinate .

The geometry of graphs and coordinate points is termed as coordinate geometry .
