Find out what half of 39° (angle ABD) Then subtract that from 180° (angle ABE). When the plain flus faster angle (ABD) gets smaller and angle (ABE) gets bigger. Hope that helps.
Answer:
The % growth rate is 15.8%.
Step-by-step explanation:
Let the function is given by 
, where f(w) is the number of a specific product produced after w weeks.
Now, given for w = 0, f(0) = 190 = a
So, the function becomes 
............. (1)
Now, it is also give that at w = 1, f(1) = 220.
So, from equation (1) we get,
⇒ b = 1.15789.
Now, b = 1 + r
⇒ 1.15789 = 1 + r
⇒ r = 0.15789
Therefore, the % growth rate is 0.15789 × 100% = 15.8% (Approx.)
The percentage discount will be 9%.
<h3>How to calculate the value?</h3>
From the information given, the item he wants to buy is priced at $13, before discount and tax and after the discount, and before tax, the price is $11.83.
The percentage discount will be:
= (13 - 11.83)/13 × 100
= 1.17/13 × 100
= 9%
Therefore, the percentage discount will be 9%.

Answer:
r = -1
Step-by-step explanation:
(y2-y1)/(x2-x1)=m
(r,7)=(x1,y1) and (3,4)=(x2-y2) and m=-3/5
so plug in...
(4-7)/(4-r)=-3/5
then solve for r which will get that r = -1
numerator: 4-7=-3
denominator: 4-r=5 -> 4-5=0+r -> -1=r
