Take a look at it.  We know it's a cone, right?  So that answers your 3rd question. The base (or the part that it sits on if you put it down), is a circle.  The other parts it can't sit on without rolling, so it has to be that circular side.  And if that's a circle, that means that any line from the center to the outside 'circumference' is the radius.  This means that the answer is A.

Simplify 3-(4x-5)+6.
Leviafan [203]
3 + -4x = 5(x +6)

Re-order the terms:

3 + -4x = 5(6 + x)
3 + -4x = (6 . 5 + x . 5)
3 + -4x = (30 + 5x)

Solving:

3 + -4x = 30 + 5x

Solving for variable "x"

Move all terms containing "x" to the left, all the other terms to the right.

Add "-5x" to each side of the equation.
3 + -4x + -5x = 30 + 5x + -5x

Combine like terms: 
-4x + -5x = -9x
3 + -9x = 30 +5x + -5x

Combine like terms: 
5x + -5x = 0
0 + -9x = 30 +0
3 + -9x = 30

Add "-3" to each side of the equation.
3 + -3 + -9x = 30 + 3

Combine like terms: 
3 + -3 = 0
0 + -9x = 30 + -3
-9x = 30 + -3

Combine like terms: 
30 + -3 = 27
-9x = 27

Divide each side by "-9".
x = -3

Simplifying:
x = -3

Answer: (compiled from google)

One radian is the measure of the central angle of a circle such that the length of the arc is equal to the radius of the circle.

A full revolution of a circle ( 360 ∘ ) equals  2 π   r a di a n s. This means that  1  radian = 180 ∘ π .  

The formula used to convert between radians and degrees is  angle in degrees = angle in radians ⋅ 180∘ π .

The radian measure of an angle is the ratio of the length of the arc to the radius of the circle  ( θ = sr ) . In other words, if  s  is the length of an arc of a circle, and  r  is the radius of the circle, then the central angle containing that arc measures radians.

Key Terms

arc: A continuous part of the circumference of a circle.

circumference: The length of a line that bounds a circle.

radian: The standard unit used to measure angles in mathematics. The measure of a central angle of a circle that intercepts an arc equal in length to the radius of that circle.

The  x – and  y -coordinates at a point on the unit circle given by an angle  

t  are defined by the functions  x = cos t  and  y = sin t .

Although the tangent function is not indicated by the unit circle, we can apply the formula  

tan  t = sin  t  cos  t  to find the tangent of any angle identified.

Using the unit circle, we are able to apply trigonometric functions to any angle, including those greater than  90 ∘ .

The unit circle demonstrates the periodicity of trigonometric functions by showing that they result in a repeated set of values at regular intervals.

Key Terms

periodicity: The quality of a function with a repeated set of values at regular intervals.

unit circle: A circle centered at the origin with radius 1.

quadrants: The four quarters of a coordinate plane, formed by the  x – and y -axes.

What's the answer??????????
IRISSAK [1]

Answer:

32

Step-by-step explanation:

first simplify the exponent

4^2 = 16

so u would get

2 + 16 / 2 • 5 - 10

then divide and multiply to get

2 + 8 • 5 - 10

2 + 40 - 10

then add and subtract

42 - 10 = 32

Answer:

<em>First term of the given series = 4</em>

<em>The last term of the given series = 11</em>

Step-by-step explanation:

<u><em>Explanation</em></u>

<em>Given that the sum of the series</em>

<em>                   ∑⁸ₙ₋₁  (n+3)</em>

The n^{th} term of the given sequence

           aₙ = (n+3)

Put n=1

         a₁ = 1+3 = 4

Put n=2

        a₂ = 2+3 =5

Put n=3

       a₃ = 3+3 = 6

Put n=4

     a₄ = 4+3 =7

Put n=5

    a₅ = 5+3 =8

Put n=6

   a₆ = 6+3 =9

Put n=7

  a₇ = 7+3 = 10

Put n=8

  a₈ = 8+3 =11

The sequence of the given series

          4,5,6,7,8,9,10,11

<u><em>Final answer:-</em></u>

<em>First term of the given series = 4</em>

<em>The last term of the given series = 11</em>

<em>             </em>
