Answer:2.4km/hr
Step-by-step explanation:
Speed = distance/time
Speed =4.6/2
Speed=2.3km/hr
The derivative of a function can be viewed geometrically through the slope of the graph of the function or through the slope of the tangent line at a point.
<h3>What is Function?</h3>
This is referred to as a mathematical term which is used to describe the relationship between two variables which are referred to as the independent and the dependent variable.
The derivative of a function is denoted as the rate of change of the variables and can be viewed geometrically through calculation of the slope of the graph of the function or through the slope of the tangent line at a point.
This is therefore the reason why it was chosen as the most appropriate choice.

Answer:
9) QR = 4.0
10) AC = 4.1
Step-by-step explanation:
Tan = Opps. / Adj.
9)
Tan(60) = 7 / QR
QR = 7 / Tan(60)
QR = 7 / 1.732
QR = 4.0415
QR = 4.0
10)
Tan (27) = AC / 8
AC = Tan(27) * 8
AC = 0.5095 * 8
AC = 4.076
AC = 4.1

Answers:
x = 51
y = 39
===========================================================
Explanation:
The angles 39 and x form a right angle, aka 90 degree angle. This is shown by the small square angle marker.
One equation to solve is x+39 = 90. Doing so leads to x = 51 after subtracting 39 from both sides.
Similarly, another equation to solve is x+y = 90. Plug in x = 51 and isolate y
x+y = 90
51+y = 90
y = 90-51
y = 39
