The graph represents a functional relationship. Which value is an input of the function? 8 -14 6 -2 4 2. f 0 . 4 8 10 12 14 16 18 х -2 -10 -12 -14

question 1: step-by-step explanation:

1/4 of 84 = 84÷4= 21

46

step-by-step explanation:

given

height = 168 cm

formula

height =2.47*f+54.13

solution

168 = 2.47f + 54.13             subtract 54.13 from both sides

168 - 54.13   = 2.47f             combine

113.87 = 2.47f                     divide by 2.47

113.87 / 2.47 = f                   combine

46.1 = f  

answer: 46 cm

can someone me: the midsegment through the legs of an isosceles triangle is 4 in. find the sides of the triangle if its perimeter is 20 in. ,   and point g is the centroid of the right △abc with hypotenuse ab=18 in. find cg.
