Mathematics

Finger [1]3 years ago

Answer:

  40.6 units

Step-by-step explanation:

Arc length is given by the formula ...

  s = rθ

where θ is the measure of the central angle in radians.

There are 2π radians in a circle (360°), so π radians in 180°. That can be used to convert the central angle ADB to radians for use in the formula.

  ∠ADB = 360° -194° = 166°

  ∠ADB = 166° = (166/180)π radians = 83π/90 radians

Then the arc length AB is ...

  length AB = (14)(83π/90) ≈ 40.561 units

The length of arc AB is about 40.6 units.

If f(x) = x2, which of the following describes the graph of f(x - 1)? A. The graph of f(x - 1) is a horizontal shift of f(x) = x
pantera1 [17]

Answer:

A

Step-by-step explanation:

To understand this, we can look at the vertical & horizontal translations of a parabola of the form  f(x)=x^2

  • A vertically translated parabola has the form  f(x)=x^2+k, where k is the vertical shift upward when k is positive and vertical shift downward when k is negative.
  • A horizontally translated parabola has the form  f(x)=(x-a)^2, where a is the horizontal shift rightward when a is positive and horizontal shift leftward when a is negative.

When we replace x of the original function with (x-1), we have  f(x)=(x-1)^2. According to the rules, this means that the original function is shifted 1 unit right (horizontal shift).

Correct answer is A.

What is the measure of the central angle of a circle with radius 15ft that intercepts a 10ft arc
svetlana [45]
Radius = 15 feet
circumference = 2 * PI * 15 = <span> <span> <span> 94.25 </span></span></span>feet
the length of the arc is 10 feet
So the angle would equal (10 / 94.25) * 360 = <span> <span> <span> 0.1061007958 </span> </span> </span> * 360 =
=  <span> <span> <span> 38.196</span></span></span> degrees
