Answer:

3.5 feet

Step-by-step explanation:

Diameter = 7 feet

Radius = Diameter × [tex]\frac{1}{2}[/tex]

Radius = [tex]\frac{7}{2}[/tex] = 3.5 feet

The domain of y = cosec(x) includes all real numbers except for the integer multiples of [tex]\pi[/tex], where the sine function equals zero and the cosecant function is undefined.

The domain of a function is the set of all possible input values (usually x values) for which the function is defined. In the case of y = cosec(x), the cosecant function is the reciprocal of the sine function, meaning cosec(x) = 1/sin(x). Since the sine of an angle can be zero and division by zero is undefined, the domain of y = cosec(x) must exclude any x values where sin(x) = 0.

The sine function is zero at integer multiples of [tex]\pi[/tex], so the domain of cosec(x) is all real numbers except for integer multiples of [tex]\pi[/tex]

Answer:

A. 1256

Step-by-step explanation:

You have to find the radius of the shaded circle

So you can add 12 + 8 = 20

Or you can find the diameter of the two circles. The diameter of the first circle is 12 + 12 = 24 and the second circle is 8 + 8 = 16 + 20 + 40 is the diameter of the shaded circle. Since radius is half of diameter 40 ÷  2  = 20

So now since you know the radius of the shaded circle you can find the area

A = πr²

A = 3.14 x 20²

A = 3.14 x 400

A = 1256

Answer: The signup fee at Jon's Gym is $100 more than the signup fee at Bella's Gym

Step-by-step explanation:

Hi, to answer this question we have to write an equation for the cost of Bella's Gym

Jon's Gym: f(x) = 30x + 150

Bella's Gym has a signup fee of $50 and charges $45 dollars per month.

So, we have to multiply the number of months (x) by the cost per month, and add the signup fee cost (50).

Bella's Gym: f(x) = 45x+ 50

Since Jon's signup fee is 150 and Bella's signup fee is 50 , the difference of both costs is 100 (150-50=100), and since Jon's gym has the more expensive fee:

The signup fee at Jon's Gym is $100 more than the signup fee at Bella's Gym

Final answer:

The statement that the signup fee at Jon's Gym is $100 more than the signup fee at Bella's Gym is true.

Jon's Gym charges $30 per month while Bella's Gym charges $45 per month; thus, Jon's Gym charges $15 less, not more.

Explanation:

Comparing the costs of gym memberships at Jon's Gym and Bella's Gym requires analysis of the initial signup fees and the monthly rates. The function for Jon's Gym, f(x) = 30x + 150, indicates a signup fee of $150 and a monthly rate of $30. Bella's Gym has a signup fee of $50 and a monthly rate of $45. To determine the true statement, we compare these numbers directly:

The other statements provided in the question can be dismissed as false:

Therefore, the correct statement is that The signup fee at Jon's Gym is $100 more than the signup fee at Bella's Gym.

Answer:

Ordered pair of YZ is (-5,-7) and magnitude of YZ is 8.602

Step-by-step explanation:

Given data:

Two pairs Y (5,4) and Z (0, -3)

To find: ordered pair of YZ

YZ = Z - Y = (0-5, -3-4)

                 = (-5, -7)

Hence ordered pair of YZ is (-5,-7)

To find: magnitude of YZ.

Here Y and Z are initial and final points of vector. Magnitude of YZ is distance between points Y and Z. Distance formula is

Distance = [tex]\sqrt{(x2-x1)^{2} + (y2-y1)^{2} }[/tex]

magnitude of YZ =  [tex]\sqrt{(0-5)^{2} + (-3-4)^{2} }[/tex]

                             = [tex]\sqrt{74}[/tex]

                             = 8.602

Another method:

magnitude of YZ = |YZ|

|YZ| = [tex]\sqrt{(-5)^{2} + (-7)^{2} }[/tex]  ...............(since |xy| = [tex]\sqrt{(x)^{2} + (y)^{2} }[/tex]

       = [tex]\sqrt{74}[/tex]

       = 8.602

magnitude of YZ = 8.602

the lowest number her is 68 and the highest is 99

99-68=31

Answer:

31 is the range

Step-by-step explanation:

the range is the number between the highest data and the lowest data. You take your largest number in the data and subtract it from the highest.

The equation that can be used to find the length of side x is:

cos(25°) = x / 32.

The equation that can be used to find the length of side x is:

cos(25°) = x / 32

This equation is based on the trigonometric ratio tan, which is defined as

the opposite side over the adjacent side.

In this case, the opposite side is x and the adjacent side is 32.

We know the angle between these two sides is 25°, so we can use the

tan function to solve for x.

x = cos(25°) * 32

x = 14.65 cm

Therefore, the equation that can be used to find the length of side x is:

cos(25°) = x / 32

The answer is D: sin 11pi/6

<3

Step-by-step explanation:

The expression that is equivalent to the given expression is Sin(11π/6).

The given trigonometric expression is: [tex]Sin \frac{7\pi }{6}[/tex]

[tex]Sin\frac{7\pi }{6}[/tex] can be written as [tex]Sin(\pi +\frac{\pi }{6} )[/tex]

The value of [tex]Sin(\pi +\theta)[/tex] is [tex]-Sin\theta[/tex].

So, [tex]Sin(\pi +\frac{\pi }{6} )=-Sin\frac{\pi }{6}[/tex]

We know that

[tex]Sin(2\pi -\theta)=-Sin\theta[/tex]

Or, [tex]-Sin\theta=Sin(2\pi -\theta)[/tex]

So, [tex]-Sin\frac{\pi }{6} =Sin(2\pi -\frac{\pi }{6} )[/tex]

[tex]-Sin\frac{\pi }{6} =Sin\frac{11\pi }{6}[/tex]

So, the required expression is [tex]Sin\frac{11\pi }{6}[/tex].

Therefore, the expression that is equivalent to the given expression is Sin(11π/6).

Answer:

x = { 3, -2 }

Step-by-step explanation:

Let's actually find the solutions to | X+10 | = 3x - 2.  Because of the absolute value operator this breaks down into two simpler problems:

1) x + 10 = 3x - 2, or 12 = 4x.  Then x = 3

2) -(x + 10) = 3x - 2,  or -x - 10 = 3x - 2,  or  -8 = 4x.  Then x = -2

Answer:

17.96

Step-by-step explanation:

To find the hypotenuse we are will have to use Sine, since we are only given the degree and opposite leg. [tex]sin(degree)=\frac{Opposite}{Hypotenuse}[/tex]

[tex]sin(63)=\frac{16}{x}[/tex]

Let's cancel the x on the right side by multiplying both sides by x

sin(63)x = 16

Divide both sides by sin(63)  [Or 0.866, depending on the type of calculator you have]

sin(63)x ÷ sin(63) = 16 ÷ sin(63)

x = 17.9572198

Answer: hamburger $3.00

Coke $1.50

Step-by-step explanation:

2hamburgers & 3cokes= $10.50

4hamburgers & 4cokes= $18.00

Let hamburger represent H

And coke represent C

2H +3C= 10.50.......equation 1

4H+4C= 18.00.......equation 2

2H =10.50 -3C...........equation 3

The 4H can be rewriting as

2(2H) right

So substitute for the 4H

So we have,

2(2H) +4C= 18

Substitute for 2H

2(10.50 -3C) +4C =18

Open the bracket

21 -6C +4C= 18

21-2C= 18

-2C = 18-21

-2C = -3

Minus cancel minus

C= 3/2 = $1.5

Substitute for c in equation 1

2H+3C =10.50

2H+3(1.5)= 10.50

2H+4.5=10.5

2H= 10.5-4.5

2H =6

H= 6/2

H=$3

So

An hamburger cost $3.00

A coke cost $1.50

sqrt(36/100) = +-6/10

You find the square root of the numerator and the denominator.
