Use this information to answer questions 13-16: On a windy morning, a hot air balloon starts rising and flying away from the top of a hill. The altitude, h, in feet,
of the balloon x hours after starting its ascent from the hill, can be modeled by the function
h(x) = -16x+ 64x + 80. use desmos calculator
There is a positive and negative x intercept for this function. What is the positive x-intercept? Explain what this
X-intercept represents in the given situation.

for this case we have by definition, if two lines are perpendicular, then the product of their slopes is -1.

then, given the following line:

so,

we are looking for m_ {2}:

then, the line is given by:

we find "b" replacing the given point:

finally, the equation is:

option c

i can you with this answer

step-by-step explanation:

the answer would be d.

step-by-step explanation:

move all variables to the left side and all constants to the right side

(x−3)^2+(y−1)^2=16

this is the form of a circle. use this form to determine the center and radius of the circle.

( x − h ) 2 + ( y − k ) 2 = r 2

match the values in this circle to those of the standard form. the variable   r   represents the radius of the circle,   h   represents the x-offset from the origin, and   k   represents the y-offset from origin.

r = 4

h = 3

k = 1

the center of the circle is found at   ( h , k ) .

center:   ( 3 , 1 )

these values represent the important values for graphing and analyzing a circle.

center:   ( 3 , 1 ).

radius:   4

the answer for this is 0.25 km. : )
