Answer:
Step-by-step explanation:
Because that's the equation given.
To solve for x, isolate the variable and then divide by the coefficient.
Answer:
<h3>lt = lo/cos²θ</h3>
Step-by-step explanation:
Given the intensity of the transmitted light It and θ are related by the equation Cosθ= √ Io/It, we are to write lt as a function of lo
Given the equation
Cosθ= √ Io/It
Let us make lt the subject of the formula;
square both sides of the equation
(Cosθ)²= (√ Io/It)²
cos²θ = lo/lt
cross multiply
ltcos²θ = lo
divide both sides by cos²θ
ltcos²θ/ cos²θ= lo/cos²θ
lt = lo/cos²θ
Hence the expression of lt as a function of lo is lt = lo/cos²θ
<span>Alex is 1.6 m tall
and
Noah is 1.5 times as tall as Alex
= 1.6 m x 1.5 = 2.4m
1 m = 100 cm
2.4 m = 2.4 x 100 = 240 cm
answer
Noah is 240 cm</span>
