Y is 85% of 60
Equation: Y = P% * X
Solving our equation for Y
Y = P% * X
Y = 85% * 60
Converting percent to decimal:
p = 85%/100 = 0.85
Y = 0.85 * 60
Y = 51
Answer:
7-8i
Step-by-step explanation:
to find as complex conjugate, simply change the sign of the imaginary pert (the part with the i). this means that is either goes from positive to negetive or from negetive to positive
as as general rule,the complex conjugate of a +bi is a-bi
Answer: 20,000
Step-by-step explanation:
We can estimate the product of 5 and 4,257 by multiplying 5 by 4,000
5 * 4,000 = 20,000
The product of 5 and 4,257 is about 20,000
The real answer (not an estimate)
21,285
That is around 20,000 so we are correct
Y=1/16x^2
multiplying both sides by 16 we get:
16y=x^2
The general form of a parabola is:
(x-h)^2=4p(y-k)
thus
4p=16
p=4
The parabola opens upwrd:
Focus: (h,k-p)
(0,0-4)
=(0,-4)
Directrix: y=-4
