Answer:

A i believe

Step-by-step explanation:

Although nicotine is addictive, most of the severe health effects of tobacco use comes from other chemicals. Tobacco smoking can lead to lung cancer, chronic bronchitis, and emphysema. It increases the risk of heart disease, which can lead to stroke or heart attack.People who smoke cigarettes are 15 to 30 times more likely to get lung cancer or die from lung cancer than people who do not smoke. Even smoking a few cigarettes a day or smoking occasionally increases the risk of lung cancer.

The current value of a baseball card is 50 times its original value v (in dollars). The baseball card is worth $62. Write and so

ehidna [41]

If the current value of the baseball car is 50 times its original value, its original value will be its current value divided by 50.

Let $v$ represent the current value of the baseball card. We know form our problem that $62 is 50 times the original value, $v$ , of the baseball card, so translating this statement to an equation we get:
$62=50v$
$v= \frac{62}{50}$
$v=1.24$

We can conclude that the original value of the baseball card was $1.24.

Solve Tan^2x/2-2 cos x = 1 for 0 < or equal to theta < greater or equal to 1.

mixer [17]

Answer:

x = theta = 0°

Step-by-step explanation:

Given the trigonometry function

Tan²x/2-2 cos x = 1

Tan²x-4cosx = 2 ... 1

From trigonometry identity

Sec²x = tan²x+1

tan²x = sec²x-1 ... 2

Substituting 2 into 1, we have:

sec²x-1 -4cosx = 2

Note that secx = 1/cosx

1/cos²x - 1 - 4cosx = 2

Let cosx. = P

1/P² - 1 - 4P = 2

1-P²-4P³ = 2P²

4P³+2P²+P²-1 = 0

4P³+3P² = 1

P²(4P+3) = 1

P² = 1 and 4P+3 = 1

P = ±1 and P = -3/4

Since cosx = P

If P = 1

Cosx = 1

x = arccos1

x = 0°

If x = -1

cosx = -1

x = arccos(-1)

x = 180°

Since our angle must be between 0 and 1 therefore x = 0°

If -12-4(-2x)= 4 then what is x?

11111nata11111 [884]

Answer:

$\boxed{\boxed{\sf x=2}}$

Step-by-step explanation:

$\sf -12-4\left(-2x\right)=\:4$

First, let's remove parentheses:

$\sf -12-4\times -2x=4$

Simplify, multiply, 4 * -2x = -8x:

$\sf -12-(-8x)=4$

** Apply rule: - ( -a )= a

$\sf 12+8x=4$

Now, let's regroup terms

$\sf 8x-12=4$

Add 12 to both sides:

$\sf -12+8x+12=4+12$

Simplify, 4 + 12= 16

$\sf 8x=16$

Divide both sides by 8:

$\sf \cfrac{8x}{8}=\cfrac{16}{8}$

$\sf x=2$

Yes, it is possible because there are 4 different directions you can travel on a coordinate plane: up, down, left and right. So the answer is (1,9) (1,1) (5,5) and (-3,5)
