Answer:
Step-by-step explanation:
Population t years after 2000 = 736,000 × 1.0149^t
736,000 × 1.0149^t = 1,000,000
1.0149^t = 1,000,000/736,000 = 125/92
Take log base 1.0149 of both sides
t ≈ 20.7
Population exceeds a million in 2021
Answer:
12
Step-by-step explanation:
if h=5
then <u>h+7</u> = <u>5+7</u> = <u>12</u>
Answer:
10.44 m
Step-by-step explanation:
Solve this as a triange. The base is 3m and the perpendicular is 10m. The angle between the base and wall is 90° so it will be a right angled triangle.
Solve this by Pythagoras theorm:
let length of ladder is c
base is b
And perpendicular is a
Acc to Pythagoras theorem:
C² = a² + b²
C² = 10² + 3²
C² = 100 + 9
C² = 109
√C² = √109
C = 10.44m
