find to the nearest cm the length of a shadow of a 4m flag pole when the elevation of the sun is 58°​

5cm

Step-by-step explanation:

Given

Height of the pole = 4m = opposite

Angle of elevation = 58 degrees

Required

length of shadow(hypotenuse)

Using the trig identity

Sin theta = opp/hyp

Sin 58 = 4/x

x = 4/sin58

x = 4/0.8480

x = 4.71cm

x ≈ 5cm

Hence the length of the shadow is 5cm to the nearest cm

correct choice is b

step-by-step explanation:

when you calculate the average rate of change of a function, you are finding the slope of the secant line between the two points. for the function the average rate of change from point to point can be calculated as

to find the average rate of change from day 2 to day 10, note that at day 2, 8 houses were sold, so a(2,8) and at day 10, 2 houses were sold, so b(10,2). thus,
