What is the explicit rule for the geometric sequence? 600, 300, 150, 75, ...

pochemuha

Answer:

Step-by-step explanation:

Hello, this is a geometric sequence so we are looking for a multiplicative factor.

$a_0=600\\\\a_1=a_0 \cdot \boxed{\dfrac{1}{2}} = 300 = 600 \cdot \boxed{\dfrac{1}{2}}\\\\a_2=a_1 \cdot \boxed{\dfrac{1}{2}} = 150= 300 \cdot \boxed{\dfrac{1}{2}}\\\\a_3=a_2 \cdot \boxed{\dfrac{1}{2}} = 75 = 150 \cdot \boxed{\dfrac{1}{2}}$

So, the explicit formula is for n

$\boxed{a_n=a_0\cdot \left(\dfrac{1}{2}\right)^n=600\cdot \left(\dfrac{1}{2}\right)^n}}$

Hope this helps.

Do not hesitate if you need further explanation.

Thank you

Use a special right triangle to express sin 45 degrees as a fraction

Alekssandra [29.7K]

Answer:

Step-by-step explanation:

in a right angled triangle angles given are 45,90

Then third angle is also 45 °

as two angles are 45° each.

Then sides are also equal.

Let the equal sides be each =x

then hypotenuse=√(x²+x²)=√(2x²)=x√2

sin 45°=x/(x√2)=1/√2
