3tan(x) = 2sin(2x) from [0,2 pi)
(Please explain steps)
Answer:
The answer is "[tex]\bold{\frac{\pi}{6}}[/tex]"
Step-by-step explanation:
[tex]\to 3 \tan(x) = 2 \sin(2x) \\\\[/tex]
[tex]\to 3 \frac{\sin x}{\cos x} = 2 2\sin x \cos x \\\\\to 3 \frac{\sin x}{\cos x} = 4\sin x \cos x \\\\\to \frac{\sin x}{\cos x \sin x \cos x } = \frac{4}{3} \\\\\to \frac{1}{\cos^2 x } = \frac{4}{3} \\\\\to \sec^2 x = \frac{4}{3} \\\\\to \sec x = \frac{2}{\sqrt{3}} \\\\\to \sec x= \sec \frac{\pi}{6} \\\\ \to x= \frac{\pi}{6}[/tex]

1. Is ABCD a translation, rotation, or reflection of ABCD? Explain how you can tell.
Answer:
1. Reflection
2. rotation and reflection
3. b', b''
4. 26.3
Step-by-step explanation:
1. It is like looking in a mirror. Its is being reflected across the y axis
2. It is rotated 90 degrees to the right. Then reflected over the x axis.
3. they are the same
4. It is the same as A" B" C" D" so the lengths are the same and you just add them.

Step-by-step explanation:
Is a triangle with sides 4, 6, and 8 a right triangle? Explain your thinking.
Answer:
No it's not
Step-by-step explanation:
In a right triangle the longest side is always the Hypotnuse. With legs a and b and Hypotnuse c, all right triangle follow the Pythagoream Theorem (a^2+b^2=c^2)
If this is a right triangle then it should also follow this rule.
8^2=4^2+6^2
64=16+36
64≠52
So this isn't a right triangle
We can find the solution to the answer by using the Pythagorean Theorem.
a² + b² = c²
4² + 6² = 8²
16 + 36 = 52
8² = 64
52 ≠ 64.
Since 4² + 6² does not equal 8², a triangle with the sides 4, 6, and 8, are not a right triangle.
Simplify: 70x/2x.

Marty paid $45 for a jacket that had been marked down 25%. What is the original price of the jacket?
Answer:
$60
Step-by-step explanation:
Since the jacket is marked down 25%, it is now at the value of 75%.
75% of the value is $45.
100% of the value is=45×100/75=$60
Therefore, the original price of the jacket is $60.

Dana bought 12 pizzas for a Math Club party. Some were pepperoni pizzas that $11.00 each,
and the rest were mushroom pizzas that cost $9.50 each. She paid $124.50 for the pizzas. How
many pepperoni pizzas did she buy
Answer:
7 pepperoni pizzas
Step-by-step explanation:
First, you take the biggest number and subtract it by 9.5 until you get a number that can be divided into 11 which is 77.
Answer:
7 pepperoni pizzas
Step-by-step explanation:
Where p = # of pepperoni pizzas and m = # of mushroom pizzas
124.50 = 11p + 9.5m
Now you need to guess and check:
Use this equation: (124.5 - 11 * p) / 9.5 and replace p with whole numbers until you get a whole number as the output
I got p=7 and m=5
So she bought 7 pepperoni pizzas
