Answer:
27.0 feet
Step-by-step explanation:
Length of an arc (s) = 2πrθ/360................. Equation 1
Where r = radius of the circle, θ = angle in degree substends by the arc at the center of the circle.
From the question,
Given: r = 9 feet, θ = 3 radian = 3 (57.2950) = 171.89°
Constant: π = 3.14
Substitute these values into equation 1
s = 2(3.14)(9)(171.89)/360
s = 9715.2228/360
s = 26.99 feet
s ≈ 27.0 feet
Answer: 1st unique 2nd nothing 3rd more than 1
Step-by-step explanation:
7w*(<span>5-6/w)=((w-28)/7w)*7w
35w-(42w/w)=w-28
35w-42=w-28
34w=14
w=14/34
w=7/17</span>
Answer:
OPTION A
OPTION C
Step-by-step explanation:
A relation becomes a function when it satisfies the following two conditions:
(i) Any element from the domain can only be mapped to only element in the co-domain.
(ii) No element in the domain should be left unmapped.
Note that an element in the co-domain need not have a pre - image.
OPTION A: Every element has an image and no element is mapped to two different elements on the co - domain. so, it is a function.
OPTION B: The element 9 is mapped to both 4 and 6. Condition (1) is not satisfied. So, it is not a function.
OPTION C: Both the conditions of a function are satisfied. So, OPTION C is a function. Note that the element 8 in the co - domain does not have a pre - image but it is still a function.
OPTION D: Element 1 in the domain is mapped to two elements. Violation of Condition (i). So, it is not a function.
