What is an equation for a sine curve with amplitude 2
Naya [18.7K]

ANSWER

y = 2 \:  \sin(x)

EXPLANATION

A basic sine curve has equation in the form:

y = a \:  \sin(x)

Where 'a' is the amplitude.

In this case a=2 because the amplitude is 2.

y = 2 \:  \sin(x)

For a transformed sine function, the general equation is:

y = a \:  \sin(bx + c)  + d

where a=2 is still the amplitude

y = 2 \:  \sin(3x + \pi)

This is also a sine function with an amplitude of 2.

Others include:

y = 2 \:  \sin(x + 1)

y = 2 \:  \sin(4x - \pi)

e.t.c

A piano has 88 keys. The ratio of white keys to black keys is 13.9. How many black keys does a piano have?
ladessa [460]
Black keys=b
white keys=w
b+w=88|·9
w:b=13/9⇒9w=13b
9b+9w=792
13b+9b=792
22b=792|:22
b=36 keys
w=88-36
w=52 keys
