Enter the amplitude of the function f(x) . f(x)=3/4cos(3x)+4
Alisiya [41]

Answer:

The amplitude is \frac{3}{4}

Step-by-step explanation:

Let f(x) be a sinusoid function that has the following format:

f(x) = bsin(wx + s) + h

Then b is the amplitude of the function

h is the vertical displacement of the wave

s is the phase angle

\frac{2\pi}{w} is the period.

In this problem f (x) = \frac{3}{4}cos(3x) +4

Then \frac{3}{4} = b

Therefore the amplitude of the function is \frac{3}{4}

The amplitude is a measure of the vertical size of the sinx wave

Sketch the following to help answer the question. Kite QRST has a short diagonal of QS and a long diagonal of RT. The diagonals
Natalija [7]
The two diagonals intersects at right-angle for a kite

the long diagonal also bisects the short diagonal so QP = PS = QS/2 = 6/2 = 3

QPR is a right-angle triangle with QR at 5 and QR at 3

RP = sqrt (5^2 - 3^) = 4m

Need help please, thanks!

Given:
1 inch : 18 kilometers

Let us use the ratio and proportion method:

a:b = c:d where ad = bc

0.8 inches is <u>14.4 kilometers</u>

1 : 18 = 0.8 : x
x = 0.8 * 18
x = 14.4 km

1.4 inches is <u>25.2 kilometers</u>

1: 18 = 1.4 : x
x = 18 * 1.4
x = 25.2 km

2.1 inches is <u>37.8 kilometers</u>

1 : 18 = 2.1 : x
x = 18 * 2.1
x = 37.8 km
