The positive solution to the equation x^2- 4 = 6

VARVARA [1.3K]

Answer:

In the form of $a+\sqrt{b}$ ,

a = 3
b = 13

Explanation:

The equation can be rewritten as:

$x^{2} -6x-4=0$

Find the solutions using the quadratic formula:

a = 1
b = -6
c = -4

$x=\frac{-b+-\sqrt{b^{2}-4ac} }{2a} \\\\=\frac{-(-6)+-\sqrt{(-6)^{2} -4(1)(-4)} }{2(1)} \\\\=\frac{6+-\sqrt{36+16} }{2} \\\\=\frac{6+-\sqrt{52} }{2} \\\\=\frac{2(3)+-2\sqrt{13} }{2} \\\\=\left \{ {{x_{1}=3+\sqrt{13} } \atop {x_{2}=3-\sqrt{13} }} \right.$

Find the solution that's positive:

$\left \{ {{x_{1} = 3+\sqrt{13} = 6.605551275... } \atop {x_{2} = 3-\sqrt{13} = -0.605551275... }} \right$

Therefore, the solution would be $3+\sqrt{13}$ .

In the form of $a+\sqrt{b}$ ,

a = 3
b = 13

sammy [17]

Answer:

a) 92.30=26m+0.3t

b) 221 texts

Explanation:

If we plug in 1 for the month variable we get

92.30=26+0.3t

subtract 26 from both sides and we get 66.3=0.3t

Divide by 0.3 and we get t=221

Answer:

The amount of potassium chloride that can dissolve in water increases by 0.3 grams for every 1 degree Celsius increase in temperature.

Explanation:

Given

$A = 27 + 0.3C$

Required

Interpret 0.3

We make use of the following illustration to answer this question.

Let C = 1

$A = 27 + 0.3*1 = 27 + 0.3 = 27.3$

Let C =2

$A = 27 + 0.3*2 = 27 + 0.6 = 27.6$

Let C = 3

$A = 27 + 0.3*3 = 27 + 0.9 = 27.9$

Notice that when the values of C increases by 1(i.e. from 1 to 2 and 2 to 3), the values of A increases by 0.3

i.e.

$27.9 - 27.6 = 27.6 - 27.3 = 0.3$

Hence, option D is true
