Angles C and D are supplementary, or they add up to 180.
b = 180 - 75 - (180 - 127)
Hope this helps!
In the 9th century, Arab writers usually called one of the equal factors of a number jadhr (“root”), and their medieval European translator used the Latin word radix (from which derives the adjective radical). Radix is the Latin for root, and radical is the name of the square root symbol.
Answer:
simple
Step-by-step explanation:
-12r+8-2r+2
-14r-10
The decay factor for the annual rate of change of - 55 % is 0.45.
A quantity must vary by a specific percentage each time period in order for growth or decay to be exponential.
With the function displayed to the right, you may represent exponential growth or decay.
A(x) = a( 1 + r)ˣ
Where A is the amount after x time periods, a is the initial amount, x is the number of time periods, and r is the rate of change.
Now, we have the annual rate of change as:
r = - 55 % = - 55 / 100 = - 0.55
From the function A(x) = a( 1 + r)ˣ , the corresponding factor is 1 + r.
So, let B = 1 + r
B = 1 + r
B = 1 + (- 0.55)
B = 1 - 0.55
B = 0.45
Now, the value of B is less than 1 therefore, the corresponding decay factor is 0.45.
