Use the information to answer the following questions.

1 answer:

5 0

70/3

6x > 220 - 80
220 - 80 = 140

6x > 140

Divide 6 on all terms & simplify.

6x/6 > 140/6

Divide x by 1 and cancel common factor 140/6

x > 140/6

Factor 2 out of 140

x > 2(70) / 6

Cancel common factors
Factor 2 out of 6

x > 2 • 70 / 2 • 3

Cross out both of the 2’s and rewrite expression

x > 70/3 or (70/3 , ♾ )

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

Two students from a group of eight boys and 12 girls are sent to represent the school in a parade.

harkovskaia [24]

The answer is 62/95. You determine this by calculating the probability of both students being girls.

Probability first student is girl: 12/20
Probability second student is girl: 11/19
Multiply 12/20 * 11/19 = 132/380 or 0.347
Probability of both students not being girls: 1 - 0.347 = 0.653 or 62/95
