3 3/5 + 9 3/5 answer with a mixed number in simplest form

Romashka [77]

Both fractions have the same denominator so it's going to be easy. First set up your equation:

$3 \frac{3}{5} + 9 \frac{3}{5}$

Add the whole numbers:

$3 + 9 = 12$

Now add the fractions:

$\frac{3}{5} + \frac{3}{5} = \frac{6}{5}$

add both together:

$12 + \frac{6}{5} = 12 \frac{6}{5}$

$\frac{6}{5}$ is an improper fraction so change it:

$12 \frac{6}{5} = 13 \frac{1}{5}$

Since 6 is one more than 5, add 1 to the whole number and subtract the numerator and denominator(6 - 5 = 1) and make the remaining the new numerator. That leaves you with $13 \frac{1}{5}$

Your answer is $13 \frac{1}{5}$

Determine the amplitude (A), period (P), and phase shift (PS) of the function f(x)= 3sin(x-4)+9

Tpy6a [65]

ANSWER

D.
$A=3,P=2\pi,PS=(4,9)$

EXPLANATION

The given function is

$f(x) = 3 \sin(x - 4) + 9$

Comparing to the general form of a trigonometric sine function,

$f(x) = A \sin(Bx-C)+D$

$A=3$
The amplitude is absolute value of A

$|A| = |3| = 3$

$B=1$

The period is given by

$p = \frac{2\pi}{ B}$

$p = \frac{2\pi}{ 1} = 2\pi$

$C=4$

is a shift to the right of 4 units.

and

$D=9$

is an upward shift of 9 units

Therefore the phase shift is (4,9).

The correct answer is D
