To convert an angle from units of radians to the units of degrees, we need a conversion factor to multiply. From what I've learned, we just have to multiply the value 180°/<span>π. We convert as follows:

</span>a.) π/9 (180°/π) = 20°<span>


b.)−2π/3</span>(180°/π)  = -120°

Which of the quadratic functions has the narrowest graph?
topjm [15]

A quadratic function's graph being wide or narrow is determined or depended on a-term:

\large{y = a {x}^{2}  + bx + c}

If |a| has a lot of value, for example a = 2 or a = 100. The graph will get narrower if increasing the value of |a|. On the other hand, If |a| has small value, for example a = 1/2 or a = 1/10000. The graph would be wide.

Also it does not matter if a-term is negative or not since a-term being positive or negative determines if a parabola is upward or downward. Only |a| determines how narrow/wide the graph is.

From the question, it is clear that the parabola y = 2x^2 is the narrowest graph since it has the highest |a| value out of all choices.

Answer

  • y = 2x^2

AB=10, AD=24. What is the value of AC+AD?<br><br>​
Rainbow [258]

Answer:

52

Step-by-step explanation:

Given:

AB = 10, AD =24

Required:

Value of AC + BD

SOLUTION:

AC = BD (both are diagonals of the rectangle)

Use pythagorean theorem to find AC.

Thus:

AB² + AD² = BD²

Plug in the values

10² + 24² = BD²

676 = BD²

√676 = BD

26 = BD

BD = AC = 26

Therefore,

AC + BD = 26 + 26 = 52

1. A boat is 18 ft away from a point perpendicular to the shoreline. A person stands at a point down the shoreline so that a 68°
slega [8]

Answer:

19.4 feet

Step-by-step explanation:

When calculating distances using perpendicular angles, we use trig functions such as Sin, Cos, and Tan.

  • Sine is defined in a perpendicular triangle as the ratio of the opposite side to the angle over the hypotenuse.
  • Cosine is defined in a perpendicular triangle as the ratio of the adjacent side to the angle over the hypotenuse.
  • Tangent is defined in a perpendicular triangle as the ratio of the opposite side over the adjacent side.

Because our angle and know side value are across from each other and we need to know the hypotenuse, we chose to use Sine.

We set up the equation sin (68) = \frac{18}{h}.

We isolate h by multiplying h across the equal sign and dividing sin (68) across as well. sin (68) = \frac{18}{h}\\hsin (68) = \frac{18}{h}*h\\hsin (68) = 18\\\frac{hsin (68)}{sin (68)} =\frac{18}{sin (68)} \\

And finally we have h=\frac{18}{sin (68)}. We input to calculator.

h=\frac{18}{0.92718} \\h=19.4 feet

See the attached picture below showing the shore with the boat out at sea and the position of the person.
