Which equation is quadratic in form?2(x + 5)2 + 8x + 5 + 6 = 0
x6 + 6x4 + 8 = 0
7x6 + 36x3 + 5 = 0
4x9 + 20x3 + 25 = 0

Answers

Answer: Option 1 is correct.

Step-by-step explanation:

As we know that the quadratic form needs the highest degree to be '2' only.

So,

In Option 1, we have ,

2(x+5)^2+8x+5+6=0\n\n2(x^2+10x+25)+8x+11=0\n\n2x^2+20x+50+8x+11=0\n\n2x^2+28x+61=0\n\n\text{ Hence , it is the required quadratic form. }

Hence, Option 1 is correct.

Answer:

Option 1 is correct.

Step-by-step explanation:

Given the equations we have to choose the equation which is in quadratic form.

Quadratic form of equation is of the the form

ax^2+bx+c=0

The quadratic form needs the degree to be '2' only.

Option 1:

2(x+5)^2+8x+5+6=0

(a+b)^2=a^2+b^2+2ab

2(x+5)^2+8x+5+6=0\n\n2(x^2+10x+25)+8x+11=0\n\n2x^2+20x+50+8x+11=0\n\n2x^2+28x+61=0\n\n\text{which is of degree 2.}

\text{Hence , it is the required quadratic form. }

Hence, Option 1 is correct.  

Rest three equations are not of degree 2 therefore not in quadratic form.

To best estimate the quotient in scientific notation. what number should replace m?6.33x 10

1.79x 103

3 x 10"

Answers

Answer:

m = 4

Step-by-step explanation:

The complete question is:

Given:

6.33 x 10⁹ / 1.79 x 10⁵ ≈ 3 x 10^(m)

To find:

To best estimate the quotient in scientific notation. what number should replace m?

Solution:

The equation is:

6.33 x 10⁹ / 1.79 x 10⁵ = 3 x 10^(m)

Let x = 9 and y = 5 then the above equation becomes:

6.33 x 10^(x) / 1.79 x 10^(y) = 3 x 10^(m)

Since we know that the exponent property is:

quotient quotient (z^(x) )/(z^(y) ) = quotient z^(x-y)

Now converting the given equation in the form above we get:

6.33 / 1.79 x 10^(x-y)  

6.33 / 1.79 x 10^(9-5)

Now the quotient is 6.33/1.79 ≈  3.536313

quotient x 10^(9-5)

3.536313 x 10^(9-5)

Since 9-5 = 4 So

3.536313 x 10^(4)

3.536 x 10^(4)

Hence

6.33 x 10⁹ / 1.79 x 10⁵ ≈ 3.5 x 10^(4)

Hence m = 4

If u(x) = x5 – x4 + x2 and v(x) = –x2, which expression is equivalent to (U/V) (x)?a) x3 – x2
b)–x3 + x2
c)–x3 + x2 – 1
d)x3 – x2 + 1

Answers

Answer: C. -x^3+x^2-1

Step-by-step explanation:

Given Functions :u(x) = x^5 - x^4 + x^2

v(x) = -x^2

The expression equivalent to (u/v) (x) will be equivalent to (u(x))/(v(x)) , since polynomials allows division.

\text{Now, }(u/v)(x)=(u(x))/(v(x))\n\n=(x^5 - x^4 + x^2)/( -x^2)\n\n=(x^5)/( -x^2)-(x^4)/( -x^2)+(x^2)/( -x^2)...........\text{Division law of exponents}\n\n=-x^(5-2)+x^(4-2)-x^(2-2)\n\n=-x^3+x^2-x^0\n\n=-x^3+x^2-1

Hence,(u/v)(x)=-x^3+x^2-1

Which of the following values are solutions to the inequality -5 ≤ x + 5? A) -7 B) -10 C) -3

Answers

Answer:

x ≥ -10

Step-by-step explanation:

We can solve the given inequality for the variable x by subtracting 5 from both sides:

-5 ≤ x + 5

- 5        - 5

-10 ≤ x

Optionally, we can swap the sides and flip the sign:

x ≥ -10

Further Note

The '≥' sign means "greater than or equal to", which means that the variable being compared can be either the exact value of the constant or anything greater than it.
