1.	What is the additive inverse of 0/7
Answer» The additive inverse of 0/7 is 0. Step-by-step explanation: The additive inverse of any NUMBER means changing the sign of that particular number such that ADDING both the numbers GIVES the result as 0. Suppose a positive number 7, so it's additive inverse would be -7. If there is a FRACTION $\frac{-2}{9}$ , so it's additive inverse would be $\frac{2}{9}$ . Now, the fraction given in the QUESTION is (0/7); So, the additive inverse of $\frac{0}{7}$ = $-(\frac{0}{7} )$ = 0 Also, it must be noted that the additive inverse of 0 is the 0 itself.

What is the additive inverse of 0/7

Answer»

The additive inverse of 0/7 is 0.

Step-by-step explanation:

The additive inverse of any NUMBER means changing the sign of that particular number such that ADDING both the numbers GIVES the result as 0.

Suppose a positive number 7, so it's additive inverse would be -7.

If there is a FRACTION $\frac{-2}{9}$ , so it's additive inverse would be $\frac{2}{9}$ .

Now, the fraction given in the QUESTION is (0/7);

So, the additive inverse of $\frac{0}{7}$ = $-(\frac{0}{7} )$ = 0

Also, it must be noted that the additive inverse of 0 is the 0 itself.

What term should be added to expression to make it a perfect square

Answer»

in this term we can see

49a⁴ + 50a²b² + 16b⁴

= (7a²)²+(4b²)² + 50a²b² ....(1)

We can MAKE this term as a PERFECT square of

(7a²+4b²)²

= 49a⁴+ 16b⁴+ 56a²b² ...(2)

From (1) and (2) we can see that

to make 49a⁴ + 50a²b² + 16b⁴ a perfect square [= (7a²+4b²)²] we MUST add 6a²b² to it

Using Quadratic FORMULA $x = \frac{ - b ± \sqrt{D} }{2a} \\ x = \frac{5 ± \sqrt{13} }{2 \times 1} \\ x = \frac{5 ± \sqrt{13} }{2} \\ x = \frac{5 + \sqrt{13} }{2} ,\frac{5 - \sqrt{13} }{2}$

Find the zero of the polinomial x2-5x+3

Answer»

Comparing the given polynomial with ax² + bx + c = 0

a=1, b=-5 and c=3

D= b²-4ac

=(-5)²-4(1)(3)

=25-12

=13

Here, D>0

Therefore, the given polynomial has two distinct REAL roots.

Using Quadratic FORMULA

$x = \frac{ - b ± \sqrt{D} }{2a} \\ x = \frac{5 ± \sqrt{13} }{2 \times 1} \\ x = \frac{5 ± \sqrt{13} }{2} \\ x = \frac{5 + \sqrt{13} }{2} ,\frac{5 - \sqrt{13} }{2}$

Answer» Step-by-step explanation: LET the TOTAL no. of students be X. Now, A/Q, No. of students received A's grade Be = 1/5 of X = X/5 No. of students RECEIVED B's grade be = 1/4 of X= X/4 No. of students received C's grade be = 1/2 of X= X/2 No. of students received D's grade be = 10 (given) Now, Total no. of students in class will be =X = X/5+X/4+X/ 2+10 = 5x/20 + 4x/20 + 10x/20 +200/20 X = 19x/20 + 200/20 20x = 19x + 200 20x - 19x = 200 X = 200.

Of the final grade recieved by the students in a certain math course, 1/5 are a's, 1/4 are b's, 1/2 are c's and the remaining 10 grades are d's. what is the number of students in the course

Answer»

Step-by-step explanation:

LET the TOTAL no. of students be X.

Now,

A/Q,

No. of students received A's grade Be = 1/5 of X = X/5

No. of students RECEIVED B's grade be = 1/4 of X= X/4

No. of students received C's grade be = 1/2 of X= X/2

No. of students received D's grade be = 10 (given)

Now,

Total no. of students in class will be =X = X/5+X/4+X/ 2+10

= 5x/20 + 4x/20 + 10x/20 +200/20

X = 19x/20 + 200/20

20x = 19x + 200

20x - 19x = 200

X = 200.

Hence,

The total no. of students in class is 200.

$\sf{Here}\begin{cases}\sf{x_1 \:=\: 3} \\ \sf{x_2\:=\: 6} \\ \sf{y_1\:=\; 1}\\ \sf{y_2\:=\: 4}\end{cases}$

$\longrightarrow\sf\: \sqrt{(x_2\:-\:x_1)^2\:+\:(y_2\:-\:y_1)^2}$

$\longrightarrow\sf\: \sqrt{(8-3)^2\:+\:(6-1)^2}$

Hence, AB = 3√2 , BC = 2√2 & AC = 5√2

$\longrightarrow\sf\: AB + BC = AC$

$\longrightarrow\sf\: 3\sqrt{2} \:+\: 2\sqrt{2}$

$\longrightarrow\sf\: 5\sqrt{2}$

Here, we can see that points are collinear.

9z=81, Solve the given EQUATION without transposing and check your result.

To find:

The value of z.

Solution :

9z=81

Divide 9 on both sides

9z/9 = 81/9

z = 9 .

CHECKING :-

9z=81

Substitute the value of z :-

9z=81

9(9) = 81.

9 X 9 = 81

81 = 81.

LHS = RHS

Hence, VERIFIED.

Find p (0),p (1),p (2) if p (x) is 5x square -3x + 7

Answer»

<P>Step-by-step EXPLANATION:

The polynomial is

P(X) =5x^2-3x+7
Substitute p(0) inthe polynomial of x variable
P(0)=5(0)^2-3(0)+7=5×0-0+7=7
Another values also substitute in x variable
P(1)=5(1)^2-3(1)+7=5×1-3+7=5-3+7=2+7=9
P(2)=5(2)^2-3(2)+7=5(4)-6+7=20-6+7=14+7=21
