The equation y = kx represents a proportional relationship between x and y, where k is the constant of proportionality. For a mo

ving object, the equation d = st represents a proportional relationship between distance (d) and speed (s) or between distance (d) and time (t). Explain the different ways that you can define the constant of proportionality for this equation. Then describe some other equations that represent proportional relationships in the real world and explain why they’re useful

Answer:

Step-by-step explanation:

for this equation

  d=st

we can represent s as d/t

we can represent t as d/s

and in real world we have a lot of this type of equations

some of them are,

 d=m/v  ( density = mass / volume )

 C = m.c  ( heat capacity = mass x specific heat )

Find an equation of the tangent line to the hyperbola y = 3/x at the point (3, 1).
Vesna [10]
Let's find the derivative of that hyperbola in order to find a slope formula to help us with this equation.  We already have an x and y value.  The derivative is found this way:  y'= \frac{x(0)-3(1)}{x^2} so  y'=- \frac{3}{x^2}.  The derivative supplies us with the slope formula we need to write the equation.  Sub in the x value of 3 to find what the slope is: y'=- \frac{3}{3^2}=- \frac{3}{9}=- \frac{1}{3}.  So in our slope-intercept equation, x = 3, y = 1, and m = -1/3.  Use these values to solve for b.  1=- \frac{1}{3}(3)+b  so b = 2.  The equation, then, for the line tangent to that hyperbola at that given point is y=- \frac{1}{3}x+2

Complete the square f(x) = x^2 + 4x - 8 <br><br><br> PLZ help me ;c
Semenov [28]
Ok, first group x terms
f(x)=(x²+4x)-8
factor out quadratic coefient (no need but that's the step)
f(x)=1(x²+4x)-8
take 1/2 of the linear coefient and square it
4/2=2, (2)²=4
add positive and negative of it insides the parenthasees
f(x)=1(x²+4x+4-4)-8
factor perfect square
f(x)=1((x+2)²-4)-8
distribute
f(x)=1(x+2)²-4-8
f(x)=1(x+2)²-12
and, now if we wanted to find the x intercepts where f(x)=0 then
0=1(x+2)²-12
12=(x+2)²
+/-2√3=x+2
-2+/-2√3=x

x=-2+2√3 or -2-2√3
that is where the x intercept are

and completed square form is
f(x)=(x+2)²-12
