Answer:

x = - \sqrt{2}, \:  \: x =   \sqrt{2}

Step-by-step explanation:

6x^2 - 12 = 4x^2-8 \\  \\ 6 {x}^{2}  - 4 {x}^{2}  = 12 - 8 \\  \\ 2 {x}^{2}  = 4 \\  \\  {x}^{2}  =  \frac{4}{2}  \\  \\  {x}^{2}  = 2 \\  \\ x =  \pm \sqrt{2}  \\  \\ x =  - \sqrt{2}, \:  \: x =   \sqrt{2}

you earn 10 points for every coin you collect in a video game. then you find a star that triples your score. write and simplify
Tomtit [17]

Answer:

The required expression for total number of points you earn is P=10c+3p.

Step-by-step explanation:

Consider the provided information.

Let c represents the coin and p represents the points before getting star.

You earn 10 points for every coin you collect in a video game.

p=10c......(1)

You find a star that triples your score.

star=3p

Now the total number of points you earn is(P):

P=10c+3p

Substitute the value of p from equation 1.

P=10c+3(10c)

P=40c

Given that sin∅ = 1/4, 0 < ∅ < π/2, what is the exact value of cos∅?
Artemon [7]

Answer:

b

Step-by-step explanation:

Using the trigonometric identity

• sin²x + cos²x = 1 , hence

cosx = ± \sqrt{1-sin^2x}

cosΦ > 0 for 0 < Φ < \frac{\pi }{2}

cosΦ = \sqrt{1-(\frac{1}{4})^2 } = \sqrt{1-\frac{1}{16} } = \sqrt{\frac{15}{16} } = \frac{\sqrt{15} }{4} → b

I need the answer for 4. and 5.
Gwar [14]

Exercise 4

A grow from 13.1 millions to 14.4 millions means to grow

14.4-13.1 = 1.3

millions. So, the question is: which percentage of 13.1 is 1.3? Well, we have to find a number x such that

\dfrac{x}{100}\cdot 13.3 = 1.3

Solving for x, you have

x = \dfrac{1.3 \cdot 100}{13.3} \approx 9.92

Exercise 5

27% is a bit more than 25%, which is a quarter. So, we expect to find a pie chart with one slice occupying roughly one quarter of the pie. The example that best suits this requirement is B (A is almost half, and C is less than one quarter).
