One property of a rhombus is that the diagonals are perpendicular. This means that the diagonals intersect at 90 degree angles (right angles).

So we know that angle JNK is 90 degrees

angle JNK = 90 degrees
5x - 15 = 90
5x - 15 + 15 = 90+15
5x = 105
5x/5 = 105/5
x = 21

Answer: x = 21

The radius of a clock face is 8.5 centimeters. what is circumfe0rence of clock?
kondor19780726 [428]

Answer:

The circumference of clock is, 53.38 cm

Step-by-step explanation:

Circumference(C) of the circle is given by:

C = 2 \pi r          ....[1]

where, r is the radius of the circle.

As per the statement:

the radius of a clock face is 8.5 centimeters

⇒r = 8.5 cm

Use\pi = 3.14

Substitute the given values in [1] we have;

C = 2 \cdot 3.14 \cdot 8.5

Simplify:

C = 53.38 cm

Therefore,  the circumference of clock is, 53.38 cm

The parent function f(x) = log4x has been transformed by reflecting it over the x-axis, stretching it vertically by a factor of
Snezhnost [94]
The reflection over the x-axis is given by the transformation:
f₁(x) = - f(x)
Therefore, the first step is:
f₁(x) = - log(4x)

Stretching by a factor n along the y-axis is given by the transformation:
f₂(x) = n · f₁(x)
Therefore we get:
f₂(x) = -3 · log(4x)

Shifting a function down of a quantity n is given by:
f₃(x) = f₂(x) - n
Therefore:
f₃(x) = -3·log(4x) - 2

Hence, the correct answer is C) g(x) = <span>-3·log(4x) - 2</span>
