Answer:

The answers amplitude is 2.3 the period is 8 and the phase shift is 0 since there is no C as shown below

Step-by-step explanation:

$y = a \cos(bx - c) + d$

$phase = |a| = |2.3| = 2.3$

$period = \frac{2\pi}{b} \: so$

$2\pi \div \frac{1}{4} \pi = 2\pi \div \frac{\pi}{4} = \frac{2\pi}{1} \times \frac{4}{\pi} = 8$

$phase \: shift = c = 0$

The hypotenuse of a right triangle is 15cm, and the shorter leg is 9cm. Find the length of the other leg

pishuonlain [190]

Hello!

If you add up the squares of the two legs, it will equal the square of the hypotenuse. As we already have the hypotenuse, we will subtract.

225-81=144

Now we find the square root.

√144=12

Therefore, the other leg is 12 cm long.

I hope this helps!

liberstina [14]

Answer:

Step-by-step explanation:

"12 more than the quiotent of a number n of and two decreased by 4"

$\left(\dfrac{n}{2}-4\right)+12$

Simplify:

$\left(\dfrac{n}{2}-4\right)+12=\dfrac{n}{2}-4+12=\dfrac{n}{2}+8$

Put n = 4 to the expresssion:

$\dfrac{4}{2}+8=2+8=10$
