if cos(x) = -1/4 and tan(x) < 0, what is sin(2x)

Answers

Answer:

B is correct: (-sqrt15)/8

Step-by-step explanation:

The value of the x is 104.5° then the value of the sin 2x is -0.49. Then the correct option is B.

What is trigonometry?

Trigonometry deals with the relationship between the sides and angles of a right-angle triangle.

If cos(x) = -1/4 and tan(x) < 0

Then the value of the x will be

[tex]\begin{aligned} \cos x &= - \dfrac{1}{4}\\\\x &= \cos^{-1} \dfrac{-1}{4}\\\\x &= 104.5^o \end{aligned}[/tex]

Then the value of the sin 2x will be

[tex]\sin 2x = \sin 2*104.5^o\\\\\sin 2x = \sin 209^o\\\\\sin 2x = -0.4848 \approx 0.49[/tex]

Marissa has $4.70 in quarters and dimes. If she has 9 more quarters than dimes, how many of each coin does she have?
dimes
quarters

Answers

Answer:

22 dimes

10 quarters

Step-by-step explanation:

$4.70 = 0.25(q + 9) + 0.1d

4.7 = 0.25q + 0.25(9) + 0.1d

4.7 = 0.25q + 2.25 + 0.1d

2.45 = 0.25q + 0.1d

24.5 = 2.5 + d

22 = d = 22 dimes

$4.70 = 0.25(q + 9) + 0.1(22)

4.70 = 0.25q + 0.25(9) + 2.2

4.70 = 0.25q + 2.25 + 2.2

4.70 = 0.25q + 4.45

0.25 = 0.25q

1 = q

1 q + 9 q = 10 quarters

Check:

$4.70 = 0.25(q + 9) + 0.1(d)

$4.70 = 0.25(1 + 9) + 0.1(22)

$4.70 = 0.25(10) + 0.1(22)

$4.70 = 2.5 + 2.2

$4.70 = 4.7

Evaluate $\frac{33}{33\frac 13}$. Express your answer as a fraction in simplest form. (Thus the numerator and denominator should be integers whose greatest common divisor is $1$.)

Answers

Answer:

[tex]\dfrac{99}{100}[/tex]

Step-by-step explanation:

We need to evaluate [tex]\dfrac{33}{33\frac 13}[/tex]. Here, 33 is numerator and [tex]33\dfrac{1}{3}[/tex].

Firstly, we will solve the denominator.

[tex]33\dfrac{1}{3}=\dfrac{33\times 3+1}{3}\\\\=\dfrac{100}{3}[/tex]

The given expression becomes,

[tex]\dfrac{33}{33\frac 13}=\dfrac{33}{\dfrac{100}{3}}\\\\=\dfrac{33\times 3}{100}\\\\=\dfrac{99}{100}[/tex]

Hence, the required answer is 99/100.
