Answer:
6.76
Step-by-step explanation:
applying pythogorem theorem
a^2+b^2=c^2
5^2+b^2=13^2
25+b^2=169
b^2=169/25
b^2=6.76^2
b=6.76
Answer:
angle of depression ≈ 53.8°
Step-by-step explanation:
the angle of depression is the measure of the angle from the horizontal downwards from the top of the flag pole.
this angle is alternate to ∠ A and is congruent to ∠ A
using the sine ratio in the right triangle
sin A = 
= 
, then
∠ A = 
( ) ≈ 53.8° ( to 1 d.p )
Angle of depression ≈ 53.8°

Answer:
$594.03
Step-by-step explanation:
Using the exponential function;
A = Pe^-rt
Principal = $960
Rate r = 12% = 0.12
Time t = 4years
Substitute
A = 960e^-(0.12*)*4
A = 960e^-0.48
A = 960(0.61878)
A = 594.03
HEnce the worth after 4years will be $594.03
Answer:
The current price index number is $604.2.
Step-by-step explanation:
The index value is the ratio between the current value and the reference value, multiplied by 100.
In this problem, we have that:
Current value = $3.48
Reference value: $0.576
Index price = (3.48/0.576)*100 = $604.2.
The current price index number is $604.2.
