Answer:
it goes up (x) goes by 5 and (y) by 7
Step-by-step explanation:
F(x) = cos x
f'(x) = -sin x
f''(x) = -cos x
f'''(x) = sin x
f''''(x) = cos x
90/4 = 22 Remainder 2
Therefore, 90th derivative of f(x) = cos x is -cos x.
You question isn't clear, but I assume that you are asking for the slop of a line parallel to y=-(5/4)(x)+7.
The line parallel would have a slop of -5/7 and the line perpendicular would have a slop of 5/7.
The difference between the two answers is the sign of the two slopes, one is positive the other is negative
1 2/5 + 3 1/2
= 7/5 + 7/2
= ((7x2)+(7x5))/(5x2)
=(14+35)/10
=49/10
=4 9/10
16 Feet x 12 inches. 16.75 x 12 is your equation.
