Option 2:
Step-by-step explanation:
Given:
From the triangle shown below;
A triangle QRS with angle QRS = 90°, ∠QSR = 30°.
Side QR = 5, SQ = 10 and RS = 5√3
Now, we know from trigonometric ratio that,
Here, opposite side of angle QSR is QR and Hypotenuse is the side opposite angle QRS which is SQ. Therefore,
Therefore, the value of sine of 30° is one-half. So, second option is correct.
Answer:
The function of capita GDP is given by
where G(t) is in dollar and t is years after 1950.
Step-by-step explanation:
Given that,
in 1950, the per capita GDP of Australia was $1800.
The capita GDP is increased by 6.7 % per year.
In 1951, the capita GDP was increased =6.7% of $1800
The capita GDP was= $1800+ 6.7% of $1800
=$1800(1+6.7%)
In 1952, the capita GDP was increased =$1800(1+6.7%)
The capita GDP was=$1800(1+6.7%)+ 6.7% of$1800(1+6.7%)
=$1800(1+6.7%)(1+6.7)
= $1800(1+6.7%)²
=$1800(1+0.067)²
In 1952, the capita GDP was increased =$1800(1+6.7%)²
The capita GDP was=$1800(1+6.7%)²+ 6.7% of$1800(1+6.7%)²
=$1800(1+6.7%)²(1+6.7)
= $1800(1+6.7%)³
=$1800(1+0.067)³
and so on.
The function of capita GDP is given by
where G(t) is in dollar and t is years after 1950.
