The line y=3x creates an acute angle theta when it crosses the x-axis, Find the exact value of sec theta

Answers

Answer:

Sec(θ) = 3

Step-by-step explanation:

First, we know that:

Sec(x) = 1/Cos(x)

Now we have an angle θ in the intersection between the line y = 3x and the x-axis.

Here we can think of this as a triangle rectangle, such that:

x is the adjacent cathetus to θ

y is the opposite cathetus to θ

y = 3*x is the hypotenuse.

Here we also need to remember the relation:

Cos(θ) = (adjacent cathetus)/(hypotenuse)

Then we will get:

Cos(θ) = x/(3*x) = 1/3

If we multiply both sides by 3, we get:

Cos(θ)*3 = (1/3)*3 = 1

Cos(θ)*3 = 1

Now we can divide both sides by Cos(θ)

[Cos(θ)*3]/Cos(θ) = 1/Cos(θ)

3 = 1/Cos(θ)

And 1/Cos(θ) = Sec(θ)

Then:

3 = Sec(θ)

The exact value of sec theta is 3.

Answers

Answer:

x=31

y=64

Step-by-step explanation:

the angle with the double mark is 85° so the angle on the same line which is marked (x) is 31°

since sum of angles in a triangle is 180° , therefore, y= 180-85-31 which is 64°

Because these two triangles are congruent, and the sum of ALL angles are 180°

So,
x = 31° ( as shown in the picture) —————————

So really you should be solving for y.

85° + 31° + y = 180°

116° + y = 180°

y = 64° ——————————

In a lottery, the top cash prize was $615 million, going to three lucky winners. Players pick four different numbers from 1 to 59 and one number from 1 to 49 . A player wins a minimum award of $225 by correctly matching three numbers drawn from the white balls (1 through 59 ) and matching the number on the gold ball (1 through 49 ). What is the probability of winning the minimum award?

Answers

Answer:

10063571 out of 593750689 or 1.69491525424%

Step-by-step explanation:

To find probability when all variables are known, you can just multiply the numbers you need. In this case we multiply 59 * 59 * 59 *49 since these are the balls we are picking from. We can find the chance of the top prize by multiplying all the numbers. 59 * 59 * 59 * 59 * 49

Can anybody help and explain this? (Part a and b)

Answers

Answer:

Step-by-step explanation:

Part A

Given equation of the circle is,

x² + y² - 4x + 2y = b

Standard equation of the circle is given by,

(x - h)² + (y - k)² = r²

Here, (h, k) is the center and r = radius of the circle

Now we will convert this equation into a standard equation of the circle,

x² - 4x + y² + 2y = b

x² - 2(2x) + 2² + y² + 2y + 1² = b + 2² + 1²

(x² - 2(2x) + 4) + (y² + 2y + 1) = b + 4 + 1

(x - 2)² + (y + 1)² = √(b + 5)²

Therefore, (2, -1) will be the center of the given circle.

y-coordinate of the circle = -1

Part B

Since, radius of the circle is 7 units,

Therefore, [tex]\sqrt{b+5}=7[/tex]

b + 5 = 49

b = 49 - 5

b = 44
