When labeling a pre-image and it's image, we use a small tick mark. It's called a(n):
IgorLugansk [536]

Answer:

Prime

Step-by-step explanation:

If we have a point on a pre-image, we can have it labelled as A(x,y)

Now, we can write this as the image

To write this as the image, we simply have to add a mark on the A

This mark is at the upper right

We have it as A’ (x,y)

The part added is called a prime

What is the average rate of change of the function f(x)=20(14)xf(x)=20(14)x from x = 1 to x = 2? Enter your answer, as a decimal
notsponge [240]
\bf slope = m = \cfrac{rise}{run} \implies 
\cfrac{ f(x_2) - f(x_1)}{ x_2 - x_1}\impliedby 
\begin{array}{llll}
average~rate\\
of~change
\end{array}\\\\
-------------------------------\\\\
f(x)= 20(14)^x  \qquad 
\begin{cases}
x_1=1\\
x_2=2
\end{cases}\implies \cfrac{f(2)-f(1)}{2-1}
\\\\\\
\cfrac{[20(14)^2]~~-~~[20(14)^1]}{1}\implies \cfrac{20\cdot 196~~-~~20\cdot 14}{1}
\\\\\\
\cfrac{3920~~-~~280}{1}\implies \cfrac{3640}{1}\implies 3640

What is the value of d? Assume that the line is tangent to the circle.
I am Lyosha [343]

Answer:

121°

Step-by-step explanation:

  • We have been given a chord and tangent to a circle, and also a minor arc measure that is equal to 118°
  • We know that; An angle formed by a secant and tangent of circle is half of the measure of intercepted arc.

Therefore; ∠ x = 1/2 mABC

  • We can find intercepted arc by subtracting minor arc measure from 360 degrees because minor and major arcs add up to 360 degrees.

Thus;<em> 360° - 118° = 242°</em>

<em>Using the formula; ∠ x = 1/2 mABC</em>

<em>Then; d = 242/2</em>

            = 121°
