Answer:
slope = - 
Step-by-step explanation:
Calculate the slope m using the slope formula
m = (y₂ - y₁ ) / (x₂ - x₁ )
with (x₁, y₁ ) = (2, 5) and (x₂, y₂ ) = (8, 3)
m =
=
= - 
Money with Nathan in his savings account = $40
Rate of interest per annum = 5%
We know that :

In this case :
Principal = $40
Rate = 5%
Time = 1 year
Simple interest he will earn in 1 year :



Amount = Principal + Interest
Amount Nathan has to pay at the end of one year :


Thus, at the end of 1 year Nathan has to pay $42.
Therefore, simple interest Nathan will earn in 1 year = $2

Answer:
∠ CDB = 45°
Step-by-step explanation:
The measure of an inscribed angle is half the measure of its intercepted arc.
∠ CDB = 0.5 × BC = 0.5 × 90° = 45°
153 000 = 100 000 + 50 000 + 3 000
