State the amplitude and period of f(t) = -0.3sin t/3

OLga [1]

Answer:

Amplitude is 0.3; period is 6π

Step-by-step explanation:

The amplitude is |-0.3| = 0.3.

The period and frequency are related through

2π

period = ----------

b

where b is the coefficient of the independent variable; here that coefficient is 1/3.

Thus, the period here is found using b = 1/3:

period = 2π/b, or 2π/(1/3), or 6π

Helllllpppppppppp! me plz

Taya2010 [7]

use Pythagoras theorem,

a² + b² = c²

x² + 12² = 14²

x = √(14² - 12²)

x = 7.2111

x = 7.21 units.

Gi sells televisions he earns a fixed amount for each television and an additional $20 if the buyer gets an extended warranty if

Ulleksa [173]

Multiply tvs sold by cost of the warranty:

17 x 20 = $340

Subtract the total warranty from total made and divide by number of TVs.

1360 - 340 = 1020

1020/17 = 60

He earns $60 per tv

What is the value of (5.3 times 10 Superscript 4 Baseline) (4.2 times 10 Superscript 3) in scientific notation?

katovenus [111]

Answer:

$2.226X 10^8$

Step-by-step explanation:

We are to determine the value of $(5.3 X 10^4) (4.2 X 10 ^ 3)$ in scientific notation.

Given:

$(5.3 X 10^4) (4.2 X 10 ^ 3)$

STEP 1: Remove the brackets.

$(5.3 X 10^4) (4.2 X 10 ^ 3)=5.3 X 10^4X4.2 X 10 ^ 3$

STEP 2: Separate the numbers and index of 10.

$=5.3 X4.2X 10^4 X 10 ^ 3$

STEP 3: Multiply the Numbers and Index of 10

$=22.26X 10^{4+3}$

STEP 4: Simplify and write in Scientific notation

$22.26=2.226X10\\Therefore:\\22.26X 10^{4+3}=2.226X10X 10^{4+3}=2.226X10X 10^7=2.226X 10^8$

Thus:

$(5.3 X 10^4) (4.2 X 10 ^ 3)=2.226X 10^8$ in scientific notation
