Answer: 20°, 50° and 90°
Step-by-step explanation:
From the question, we are informed that the measures of the three angles whose sum is 160 are in the extended ratio 2:5:9.
The exact angle measures will then be:
= 2/(2+5+9) × 160°
= 2/16 × 160°
= 20°
= 5/(2+5+9) × 160°
= 5/16 × 160°
= 50°
= 9/(2+5+9) × 160°
= 9/16 × 160°
= 90°
Amount of Interest (I) = P * R * T /100
I = 720 * 5 * 4 /100
I = 144
Balance = Initial amount + Interest amount
B = 720 + 144 = 864
In short, Your Answer would be <span>£864

Answer:
y = -2·(1/2)^x
Step-by-step explanation:
The general form of the equation can be written as ...
y = a·b^x
where 'a' is the value of the y-intercept, and 'b' is the ratio of y-values for x-values that differ by 1.
From your table and graph, a = -2. From the table, ...
b = -1/-2 = 1/2
Then the exponential equation is ...
y = -2·(1/2)^x
