The standard form of a hyperbola is <span><span><span>x2/</span><span>a2 </span></span>− y<span><span>2/ </span><span>b2 = 1
the tangent line is the first derivative of the function</span></span></span><span>y′ = <span>b^2x/ a^2 y
hence the slope is </span></span><span>m = <span>b^2 x0 / <span>a^2 <span>x1
</span></span></span></span>Therefore the equation of the tangent line isy−x1 = b^2 x0 / a^2 x1* (x−x0)
Answer:
C. 1.2x
Step-by-step explanation:
He pays 1 x for his haircut, and an additional 20% on top of that, or an additional 0.2x. If you write that as an expression, you can simplify it like this:
You can also work it out by multiplying by 1.2 as stated in answer C. If his haircut costs $10, adding a 20% tip of $2 is the same as multiplying by 1.2.
We have that This equation simply state that P as a Function of A is equal to 0.97
From the question we are told that
P(A) = 0.97.
Generally
This equation simply state that P as a Function of A is equal to 0.97
i.e P is a Constant equation and A is a variable that changes P to 0.97

If you would like to simplify 21/78, you can do this using the following step:
21/78 = 7/26
<span><span>The result is </span>7/26 <span>(this is not a mixed number, because mixed
numbers can be made from numbers greater than 1 and 7/26 is less than 1).</span></span>
