Answer:

14.9

Step-by-step explanation:

Formula= $\sqrt{(x2-x1)^{2} +(y2-y1)^{2}$

x1=11; y1=-12; x2=6; y2=2

Putting these values in the formula, the result will be 14.866≡14.9

How do we find the factors of x2 – 64

sweet-ann [11.9K]

Answer:

The factors of x²-64 is equal to (x-8)(x+8).

Step-by-step explanation:

The given expression is:

x²-64

we know that, 8² = 64

So,

(x²-8²) = (x-8)(x+8) [As (a-b)(a+b) = a²-b²]

So, the factors of x²-64 i equal to (x-8)(x+8).

Which function represents a reflection of f(x) = Three-sevenths(2)x over the x-axis?

NemiM [27]

<u>Given:</u>

The given function is $f(x)=\frac{3}{7}(2)^{x}$

We need to determine the reflection of f(x) over the x - axis

<u>Reflection over x - axis:</u>

The translation rule to reflect over the x - axis is given by

$(x, y) \rightarrow(x,-y)$

Reflecting the function over the x - axis, we get;

$-y=\frac{3}{7}(2)^{x}$

Multiplying -1 to both sides of the equation, we have;

$y=-\frac{3}{7}(2)^{x}$

This can be written as

$g(x)=-\frac{3}{7}(2)^{x}$

Hence, the reflection of the function over the x - axis is $g(x)=-\frac{3}{7}(2)^{x}$

Thus, Option A is the correct answer.
