I think it is (0,b). Though I might be mistaken. After you plug in the numbers, it should be -3a+3a/2 and b+b/2. Once simplified that is 0/2 and 2b/2. 0/2 is just 0 and 2/2 is 1 leaving b. So the answer is (0,b).

HELP ME please!!!!!!!

Answer:

$n=20\ units$

Step-by-step explanation:

we know that

If two figures are similar, then the ratio o its corresponding sides is proportional, and this ratio is called the scale factor

In this problem the corresponding sides are

12 units and 15 units

16 units and n units

therefore

$\frac{12}{15}=\frac{16}{n}$

Solve for n

$n=\frac{15*16}{12}$

$n=20\ units$

Use a half-angle identity to find the exact value of sinPi/8

stellarik [79]

Answer:

sin(π/8) = (1/2)√(2-√2)

Step-by-step explanation:

Using the half-angle formula ...

$\sin{\dfrac{\theta}{2}}=\sqrt{\dfrac{1-\cos{\theta}}{2}}$

We can let θ = π/4 and simplify the result as follows:

$\sin{\dfrac{\pi}{8}}=\sqrt{\dfrac{1-\cos{(\pi/4)}}{2}}=\sqrt{\dfrac{1-\dfrac{\sqrt{2}}{2}}{2}}=\sqrt{\dfrac{2-\sqrt{2}}{4}}\\\\=\boxed{\dfrac{1}{2}\sqrt{2-\sqrt{2}}}}$
