Greatest whole number lying between -16 and 2​
Lostsunrise [7]

Answer:

<em>The threatest whole number in the interval is 2</em>

Step-by-step explanation:

<u>Numbers and intervals</u>

We are given the interval of numbers between -16 and 2. Since it's not specified, both endpoints of the interval are not included.

If we consider the interval as real numbers, then there are infinitely many numbers there, like -15, -12.56, -8, -2pi, 0.02, 1.99.

If we are restricted to only whole numbers, then we get a limited set of the numbers: {-15, -14, -13, -12,....,1}

Note the greatest number at the right endpoint of the interval is 1, since we are not including 2.

The threatest whole number in the interval is 2

What is the volume of this hemisphere
Goryan [66]

Answer: 294.34 m^3

Step-by-step explanation: The formula for the volume of a hemisphere is 2/3 * 3.14 * radius cubed (r^3). Plugging in the values, we have 2/3 * 3.14 * 5.2^3, and we get roughly 294.339 m^3, or rounded to the nearest hundredth, 294.34 m^3.

Hope this helped!

The point (- square-root 2/2, square-root2/2 is the point at which the terminal ray of angle theta intersects the unit circle. W
Rufina [12.5K]

Answer: The value of cosine is \frac{-\sqrt{2}} {2} and the value of cotangent is -1.

Explanation:

The given point is (\frac{-\sqrt{2}} {2}},\frac{\sqrt{2}} {2}).

Since the x coordinate is negative and y coordinate is positive so the point must be lies in second quadrant.

The distance of the point from the origin is,

r=\sqrt{(\frac{-\sqrt{2}} {2}-0)^2+(\frac{\sqrt{2}} {2}-0)^2}

r=\sqrt{ \frac{2}{4}+\frac{2}{4}}

r=1

The given point is in the form of (a,b). So we get,

a=\frac{-\sqrt{2}} {2}

b=\frac{\sqrt{2}} {2}

The formula for cosine,

\cos \theta =\frac{a}{r}

\cos \theta =\frac{\frac{-\sqrt{2}} {2}}{1}}

\cos \theta =\frac{-\sqrt{2}} {2}}

The formula for cotangent,

\cot \theta =\frac{a}{b}

\cos \theta=\frac{\frac{-\sqrt{2}} {2}}{\frac{\sqrt{2}} {2}}

\cos \theta=-1

Therefore, the value of cosine is \frac{-\sqrt{2}} {2} and the value of cotangent is -1.

______ of symmetry- ALine that divides an object into two congruent halves.
kirza4 [7]

Answer:

"A line"

Step-by-step explanation:

A line of symmetry is a line that divides an object into two congruent halves.

_____

However, not every line that does so is a line of symmetry. The vertical line in the attached diagram divides both figures into congruent halves. It is only a line of symmetry for the green figure.
