Suppose two radii of a circle determine a 45° angle, and the length of both radii is 64 yards. What is the arc length formed by
Ilia_Sergeevich [38]

The arc length formed by the 2 radio is 15.24 yards

Step-by-step explanation:

Angle between the 2 radio = 45°

Radius = 64 yards

Arc length = (45/360) (2π) (64)

= (1/8) (2π) (64

= 16π

= 16(3.14)

=15.24 yards

The arc length formed by the 2 radio is 15.24 yards

Which of the following rules could represent the function shown in the table?
kvasek [131]
ANSWER

The rule is given by the relation,

y = 2x + 1


EXPLANATION

We need to check and see if there is a constant difference between the y-values.


1 -  - 1 = 2 = 3 - 1


We can see that, there is a constant difference of 2.

This means that the table represents a linear relationship.


Let the rule be of the form,
y = mx + c


Then the points in the table should satisfy the above rule.


So let us plug in


(0,1)


This implies that,


1 =m (0) + c


1 = 0 + c


c = 1



Our rule now becomes,


y = mx + 1 -  - (1)


We again plug in another point say, (-1,-1) in to equation (1) to get,



- 1 = m( - 1)   + 1

we solve for m now to obtain,

- m=-1-1


- m =  - 2


m = 2
We now substitute back in to equation (1) to get

y = 2x  + 1

What is x? Please help fast
Firdavs [7]

Answer:

x = 47°

Step-by-step explanation:

m∠DPB + ∠BPC = 180° (Definition of a straight line)

Plug in the corresponding numbers and variables to the corresponding places:

x + 133 = 180

Isolate the variable, x. Subtract 133 from both sides:

x + 133 (-133) = 180 (-133)

x = 180 - 133

x = 47

47° is your answer.
