Answer:61.8°

Step-by-step explanation:

Length of arc=(theta)/360 x 2 x π x radius

9.7=(theta)/360 x 2 x 3.14 x 9

9.7=56.52(theta)/360

cross multiply

9.7 x 360=56.52(theta)

3492=56.52(theta)

Divide both sides by 56.52

3492/56.52=56.52(theta)/56.52

61.8=theta

theta=61.8°

Help me, please! I'll give a brainlist point! :)
Allisa [31]

Answer:

105

Step-by-step explanation:

Area of a trapezoid is given by the formula:

A = (a+b)÷2×h

(where h is the vertical height, and a and b are the parallel lines)

Substituting values given gives us:

A = (6+15)÷2×10

A = 21÷2×10

A = 10.5×10

A = 105

Units will be m² as this is area.

What are the transformations to this quadratic function y= (x+4) power of 2 - 8
I am Lyosha [343]

Answer:

Horizontal shift of 4 units to the left.

Vertical translation of 8 units downward.  

Step-by-step explanation:

Given the quadratic function, y = (x + 4)² - 8, which represents the horizontal and vertical translations of the parent graph, y = x²:

The vertex form of the quadratic function is y = a(x - h)² + k

Where:

The vertex is (h , k), which is either the <u>minimum</u> (upward facing graph) or <u>maximum</u> (downward-facing graph).

The axis of symmetry occurs at <em>x = h</em>.

<em>a</em> =  determines whether the graph opens up or down, and makes the graph wider or narrower.

<em>h</em> = determines how far left or right the parent function is translated.

<em>k</em> = determines how far up or down the parent function is translated.

Going back to your quadratic function,

          y = (x + 4)² - 8

  • The vertex occrs at (-4, -8)
  • a is assumed to have a value of 1.
  • Given the value of <em>h</em> = -4, then it means that the graph shifted horizontally by <u>4 units to the left</u>.  
  • Since k = -8, then it implies that the graph translated vertically at <u>8 units downward</u>.

What is the solution to the equation below? Round your answer to two decimal places.<br> e^x = 0.5
ASHA 777 [7]

Answer:

x = -0.69

Step-by-step explanation:

We can get this by writing the equation in the logarithmic form to base e

We have this as;

log e 0.5 = x

x = ln 0.5

x = -0.69315

To two decimal places, this is -0.69
