Ans1:  Heart shaped graph

Ans2:  option:C

Ans3:   option:D

Ans4:    option:A

Ans5:     option:D

Step-by-step explanation:

Ans1:  Heart shaped graph is not a function.

" since for a graph to be a function: any line passing through the domain and parallel to the co-domain should intersect the graph exactly once ".

also we can see from some examples in a figure attached to the answer.

Ans2:  we are given a sequence as:   -5,-15,-25,-35

as the given sequence is an Arithmetic Progression(A.P.) with a common difference

Hence the next three terms of the sequence are:   -45,-55,-65

Ans3: we are asked to find the 30th term of a sequence

Hence, the 30th term of the given sequence is 57.

Ans4: The vertical line test is used to determine if the graph is a function.

Ans5:   we are given a function f(x)=3x-5

with domain={2,4,6}

range of f(x):

when x=2  f(x)=3×2-5=6-5=1

when x=4   f(x)=3×4-5=12-5=7

when x=6   f(x)=3×6-5=18-5=13

Hence, range of f(x)={1,7,13}.

Ans6:   the given set of ordered pair is: {(4,-2),(-1,-1),(0,0),(1,-1),(4,2)}

As from the given set we could see that '4' has two images.

As '4' is mapped to '-2' and '2'{ since, the given ordered pair is (4,-2) and(4,2)}

Hence, f can't be a function.

answer: the angel abc is 30°,and the abc is a triangle where the angel bac is 90°

so ac is the half of 24=12ft,and from the pythagorean theorem we find ba

ba=√bc^2-ac^2=√576-144=√432=12√3ft

so bac is 12+12√3=12(1+√3)ft

believe it or not anna is correct good job anna give me a fist bump there u go gal
