Answer:

1.5

Step-by-step explanation:

The formula for inverse variation is xy=k. So i did 3*5 which is 15 and then I did 15*1 which is 15 and 30*0.5 which is 15. So know i know that 10 times something has to equal 15 so i do 15/10 to get 1.5 which is my answer

Rationalise the denominator of 2sq3+3sq2/4sq3+sq2

Vinil7 [7]

Answer:

$\frac{9+5\sqrt6}{23}$

Step-by-step explanation:

We can rewrite the fraction as

$\frac{2\sqrt{3}+3\sqrt{2}}{4\sqrt{3}+\sqrt{2}}$

In order to rationalize the denominator of such a complex fraction, we must multiply the fraction by the conjugate of the denominator. In this case, the conjugate of the denominator would be $4\sqrt{3}-\sqrt{2}$ . Multiplying both sides of the fraction by the conjugate of the denominator would result in the fraction:

$\frac{9+5\sqrt6}{23}$

Answer:

x = 4

Step-by-step explanation:

By intersecting chords theorem:

$8(4x + 2) = 9(4x) \\ \\ 32x + 16 = 36x \\ \\ 32x - 36x = - 16 \\ \\ - 4x = - 16 \\ \\ x = \frac{ - 16}{ - 4} \\ \\ x = 4$

Multiplying a trinomial by a trinomial follows the same steps as multiplying a binomial by a trinomial. Determine the degree and

fenix001 [56]

Answer:

The degree of polynomial is equal to 4

The maximum number of terms is equal to 5.

Step-by-step explanation:

Given the trinomials we have to find the degree and maximum possible number of terms for the product of these trinomials.

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

By distributive property,

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

$(x^4-2x^3+3x^2)+(x^3-2x^2+3x)+(2x^2-4x+6)$

Grouping like terms

$x^4+(-2+1)x^3+(3-2+2)x^2+(3-4)x+6$

Adding terms of same power

$x^4-x^3+3x^2-x+6$

Hence, The degree of polynomial is equal to 4

The maximum number of terms is equal to 5.
