Answer:
It’s 10n+12
They put the 2 n’s as an exponent
Step-by-step explanation:
The answer would be -2! :)
answer is 250 which is D Because 250 of 24%=60, so subtract 60 from 250 it will give you 190
Answer:
Choice D is correct
Step-by-step explanation:
The first step is to write the polar equation of the conic section in standard form by dividing both the numerator and the denominator by 2;

The eccentricity of this conic section is thus 1, the coefficient of cos θ. Thus, this conic section is a parabola since its eccentricity is 1.
The value of the directrix is determined as;
d = k/e = 3/1 = 3
The denominator of the polar equation of this conic section contains (-cos θ) which implies that this parabola opens towards the right and thus the equation of its directrix is;
x = -3
Thus, the polar equation represents a parabola that opens towards the right with a directrix located at x = -3. Choice D fits this criteria
Answer: -3z+8
Step-by-step explanation: add -4z and z because they are like terms and then leave the 8 alone because it’s a term.
