Explanation

Given log(x) - 2log(y):

Using logarithmic properties:

log(x) - 2log(y) = log(x) - log(y^2) = log(x/y^2)

Explanation

Use identity: tan θ + sec θ = (sin θ/cos θ) + (1/cos θ) = (sin θ + 1)/cos θ

Therefore, tan θ + sec θ = (1 + sin θ)/cos θ.

Explanation

In polio, approximately 1 out of every 200 infections leads to irreversible paralysis, often in the legs.

Though most infections are mild or asymptomatic, this small percentage represents the severe impact of the disease.

Explanation

This step-by-step reinforcement is called shaping, commonly used in language learning and behavior training.

Explanation

Area of square = 225 m², side = √225 = 15 m.

Perimeter = 4 × side = 4 × 15 = 60 m.

Cost = Perimeter × Rate = 60 × 235 = 14100.

Explanation

To find the books sold in the 4th week:

Total books = 4320

Total angle in pie chart = 360°

Books sold in 4th week = 42/360 × 4320

= 4320 × 42/360

= 4320 × 7/60

= 504
