Answer:
The angle of depression is the angle below straight ahead -- horizontal -- that an observer must look in order to see something below the observer.
Answer:
step 1
find the equation of f(x)
points
(2,1) and (0,-3)
m=(y2-y1)/(x2-x1)----------> m=(-3-1)/(0-2)---------> m=2
y-y1=m(x-x1)-----> y+3=2*(x-0)------> y=2x-3
f(x)=2x-3
step 2
find the equation of g(x)
points
(0,6) and (2,-2)
m=(y2-y1)/(x2-x1)----------> m=(-2-6)/(2-0)---------> m=-4
y-y1=m(x-x1)-----> y-6=-4*(x-0)------> y=-4x+6
g(x)=-4x+6
step 3
find the value of k
If g(x) = k* f(x)
so
-4x+6=k*[2x-3]-------> -4x+6=2kx-3k
-4x=2kx--------> k=-2
6=-3k------------> k=-2
the answer is
k=-2

U should use a website called math.way, its much faster than brainly :P

This can be found by finding the vertex of the parabola. You can find the t value using -b/2a and then plug that in to find the h value.
We are given
Mala is y years old
So, Mala =y
her sister is 4 years older than Mala
So, Sister =y+4
now, we can find sum
Sum = Mala +Sister
Sum = y +y+4
Sum = 2y+4...............Answer
