The right answer is C
Let me to explain. From the graph we know that the vertex of this parabola is . This is a<em> maximum y-value.</em> We also know that the parabola <em>opens downward, </em>so the leading coefficient is negative. Given that the function is even and the leading coefficient is negative, it follows that the graph falls to the left and right. In a mathematical language this is:

Answer ( if trying to find x ) :
x = 44
Step-by-step explanation:
5 x 7 = 35 ( area of picture )
120 -> ( area of the whole picture + frame )
120 - 35 = 85 ( area of just the frame )
factor's of 85 -> 1 ,5 ,17 ,85 ( can't be 1 by 85 inch's picture ,so you get 5 by 17 )
5 + 5 + 17 + 17 = 44 (perimeter of the frame ( perimeter formula= l + l + w + w ) )
44 inch's ( ? )
Answer:
a) The sequence of first three terms
5 , 8 , 13 ..
b) The of the sequence
a₁₀ = 104
<u><em></em></u>
Step-by-step explanation:
<u><em>Step(i):-</em></u>
Given term of the sequence
aₙ = n² + 4
put n=1
First term a₁ = 1² +4 = 1+5
put n =2
Second term a₂ = 2²+4 = 4+4 =8
Put n=3
Third term a₃ = 3² +4 = 9+4 =13
The sequence of first terms
5 , 8 , 13 ..
<u><em>Step(ii):-</em></u>
Given term of the sequence
aₙ = n² + 4
put n =10
a₁₀ = 10²+4 = 100+4 = 104
a₁₀ = 104
The of the sequence
a₁₀ = 104
<u><em></em></u>
the X is actual 7 thats it
120/5 becAuse when u multiply 1 3/5 by 8 u get 120/5 hope that helped
