Find the measure of the arc or angle indicated. Part 1. NO LINKS.​
andreev551 [17]

Answer:

Step-by-step explanation:

1)

O = center of circle (origin)

we know that the angle at the center of the circle ∠ ROS will be

180= 2(31) + ∠x

180-62 = ∠x

118° = ∠x

The supplemental angle to the 118° will be 62°

62° is the interior angle to  arc QR , so

arc QR is also 62°

3)

b/c the intercepted arc YZ = 2* 68=136

then 136+125+? = 360

? = 99°

arc ZX = 99°

5)

O= center point

we are given the two arcs  120 and 70 for both of these we know that the

interior angles will be the same.  ∠JOX  has a central angle of 120 , then

b/c triangle JOX is an isosceles,  we know that the two angles J and X of

the triangle JOX will be 1/2 of  60 , or 30 each

also for    

also ∠XOY has an interior angle of 70 so the two angle at X and Y will be 1/2 of 110 , or 55°

now add 55+30 to find X for box XYZJ

85° = ∠X

Answer:

18 sides

Step-by-step explanation:

Each exterior angle of a regular polygon = 20 deg. So the polygon has 360/20 = 18 sides

One cell phone company charges a $76 sign-up fee and $40 per month. Another cell phone company charges $136 sign-up fee and $20
WARRIOR [948]

Answer:

The cost would be same after 3 months.

Step-by-step explanation:

Given that:

Charges of first company;

Sign up fee = $76

Per month charges = $40

Let,

x be the number of months

y be the total cost.

y = 40x + 76      Eqn 1

Charges of second company;

Sign up fee = $136

Per month charges = $20

y = 20x + 136     Eqn 2

For same cost,

Eqn 1 = Eqn 2

40x + 76 = 20x + 136

40x-20x = 136 - 76

20x = 60

Dividing both sides by 20

\frac{20x}{20}=\frac{60}{20}\\x=3

Hence,

The cost would be same after 3 months.

On a adventure trail, you biked 12 mi, walked 4 mi, ran 6 mi, and swam 2 mi. What fraction of the total distance did you bike? W
galben [10]
First you want to add all of those together.
12 + 4 + 6 + 2 = 24
So there are 24 miles in total.
Next, it says she biked 12 miles so you make a fraction.
12 / 24 which can be reduced to 1/2.
She spent one half of the total distance biking.
Hope this helps!

The inverse of the logarithmic function f(x) = log0. 5x is f−1(x) = 0. 5x. What values of a, b, and c complete the table for the
Elan Coil [88]

The value of a, b and c can be calculated using the inverse function.

The calculated the value of a= 2, b=1 and c= -2.

Given:

The function is  f(x)=\log_{0.5}x and its inverse is f^{-1}(x)=0.5^x .

<h3>What is an inverse function?</h3>
  • The inverse function of a function is defined if f is a function that undoes the operation of f.
  • The inverse of f exists if and only if f is bijective, and if it exists, is denoted by f^{-1}.

Substitute the value of x= -1 in a given inverse function and calculate the value of a.

f^{-1}(x)=0.5^x\\&#10;f^{-1}(-1)=0.5^{-1}\\&#10;f^{-1}(-1)=2

Substitute the value of x  is 0 in given inverse function.

f^{-1}(x)=0.5^x\\&#10;f^{-1}(0)=0.5^0\\&#10;f^{-1}(0)=1

Substitute the value of x  is 2 in given inverse function.

f^{-1}(x)=0.5^x\\f^{-1}(2)=0.5^2\\f^{-1}(2)=-2

Therefore, the value of a= 2, b=1 and c=-2.
