100 - 85 = 15%
15% = 6
1% = 0.4
100% = 0.4 x 100 = 40
Answer: There were 40 questions.
8x + 26 = 98
8x = 72
x = 9
8x + 26 + z = 180
8(9) + 26 + z = 180
72 + 26 + z = 180
98 + z = 180
z = 82

<span>You are given the function of y=arcsin 0.9659 and you are asked to find the general solution of the function. In order to do that, you have to derive the given function. the answer would be 1/sqrt(1.035^2 + x^2)</span>
TTese are all parabolas whose axis of symmetry is the y axis. The negative coefficient means they open downwards and the positive mean they open upwards. The higher the absolute value of the coefficient is the greater the slope, so 2x^2 will be steeper than x^2 and -4x^2 will be steeper than - 2x^2.
So h(x) and j(x) are the answers.
