If John solved the equation x? - 10x + 8 = 0 by completing the
square, one of the steps in his process would be
(1) (x-5)^2 = -8
(2) (x-5)^2 = 17
(3) (x+ 4)^2 = 10x
(4) (x + 4)^2 = 10x + 16

Answer:

0.50

Step-by-step explanation:

Because decimals are correlated with fractions, and fractions are correlated with percentage.

Essentially, everything is out of a hundred. For example, 100% is max capacity(aka the votes in this question).

In decimals, 0.50 is half of 1.00 which is essentially also max capacity. Following this logic, if you convert 50% into decimal form, it will be 0.50, and 0.50 is one half of 1.00. The other half must be 0.50 then, because if you subtract it, that's what you get, and you can check by adding it together.

Hope this helps.

Step-by-step explanation:

Chord BC is a diameter of the circle as passes from the center O of the circle and its end points B,C lies on the circle so the statement is true.

A circle is a shape consisting of all points in a plane that are at a given distance from a given point, the centre.

O is the center of the Circle

Chord BC is the line segment passing from the center of circle

Chord is a line segment whose end points lies on the circle.

Diameter is defined as a line segment passing from the center of the circle whose end point lies on the circle.

A chord that passes through the centre of a circle is called a diameter, and it is the longest chord.

Hence, chord BC is a diameter of the circle as passes from the center O of the circle and its end points B,C lies on the circle so the statement is true.

Answer:

84 possible paths

Step-by-step explanation:

Given

[tex]N =3[/tex] --- 3 blocks north

[tex]E = 6[/tex] --- 6 blocks east

Required

Number of distinct path

To solve this question, we make use of the following formula

[tex]^{m+n}C_n \ =\ ^{m+n}C_m[/tex]

The above formula implies that;

On a single path, there is a total of m + n steps to get to a particular position, where each path is either in m direction or n direction.

In this case:

[tex]m = 3[/tex]

[tex]n = 6[/tex]

So, we have:

[tex]^{m + n}C_n = ^{3+6}C_6[/tex]

[tex]^{m + n}C_n = ^9C_6[/tex]

Apply combination formula

[tex]^{m + n}C_n = \frac{9!}{(9-6)!6!}[/tex]

[tex]^{m + n}C_n = \frac{9!}{3!*6!}[/tex]

Expand the numerator

[tex]^{m + n}C_n = \frac{9*8*7*6!}{3!*6!}[/tex]

[tex]^{m + n}C_n = \frac{9*8*7}{3!}[/tex]

Expand the denominator

[tex]^{m + n}C_n = \frac{9*8*7}{3*2*1}[/tex]

[tex]^{m + n}C_n = \frac{504}{6}[/tex]

[tex]^{m + n}C_n = 84[/tex]

Hence, there are 84 possible paths

[tex]^{m + n}C_m[/tex] will also give the same result

Answer:

Answer:

a)

We know that:

a, b > 0

a < b

With this, we want to prove that a^2 < b^2

Well, we start with:

a < b

If we multiply both sides by a, we get:

a*a < b*a

a^2 < b*a

now let's go back to the initial inequality.

a < b

if we now multiply both sides by b, we get:

a*b < b*b

a*b < b^2

Then we have the two inequalities:

a^2 < b*a

a*b < b^2

a*b = b*a

Then we can rewrite this as:

a^2 < b*a < b^2

This means that:

a^2 < b^2

b) Now we know that a.b > 0, and a^2 < b^2

With this, we want to prove that a < b

So let's start with:

a^2 < b^2

only with this, we can know that a*b will be between these two numbers.

Then:

a^2 < a*b < b^2

Now just divide all the sides by a or b.

if we divide all of them by a, we get:

a^2/a < a*b/a < b^2/a

a < b < b^2/a

In the first part, we have a < b, this is what we wanted to get.

Another way can be:

a^2 < b^2

divide both sides by a^2

1 < b^2/a^2

Let's apply the square root in both sides:

√1 < √( b^2/a^2)

1 < b/a

Now we multiply both sides by a:

a < b
