Answer:
Step-by-step explanation:
<h3>Part i</h3>
<u>Jennifer's account:</u>
<u>William's account can be expressed as:</u>
Because the rate of change is 14 and y-intercept is 30
<u>They will be same after x years, f(x) = g(x)</u>
- 10x + 50 = 14x + 30
- 14x - 10x = 50 - 30
- 4x = 20
- x = 5
The accounts will be same after 5 weeks
<h3>Part ii</h3>
<u>The amount in the accounts after 5 weeks:</u>
- f(5) = g(5) = 10*5 + 50 = $100
we can sue formula
where
P(t) is population after t years
P0 is initial population
k is growth rate
t is time in years since 1985
Let's assume
h(t)=P(t) is million
h_0=P_0 in million
we can replace it
and we get
..............Answer
The length of the lake as represented in the triangle ABC is 271.3 meters.
<h3>What is an equation?</h3>
An equation is an expression that shows the relationship between two or more numbers and variables.
Sine rule is used to show the relationship between the sides and angles of a triangle.
∠A + ∠B + ∠C = 180° (angles in a triangle)
60 + 43 + ∠C = 180
∠C = 77°
Using sine rule:
519/sin(77) = BC / sin(60)
BC = 461.3 m
x = 461.3 - 190 = 271.3
The length of the lake as represented in the triangle ABC is 271.3 meters.

Answer:
-4, -3, -2, -1, 0
Step-by-step explanation:
They are greater than -5 and less than 1
29.23 times 3 = 87.69
100 - 87.69 =$12.31
