Answer:
Step-by-step explanation:
Since the value of the car decreases by a common factor each year, the decay is exponential.
An exponential decay function is of the form
Therefore, the function modeling the car's decay is:
We want to determine the car's value in two years.
When t=2
The value of the car in 2 years will be A(t)=$9109.10
<span> line passes through the points (p, a) and (p, –a)
where p and a are real numbers and p ≠ 0
(p, a) and (p, –a) m = Cannot divide by ZERO, there is no slope to this Line.
slope of the line: no slope (does not exist)
equation of the line: x = p Perpendicular Line
</span><span>slope of a line perpendicular to the given line: would be m = 0, horizontal Line y= 3
</span>y- intercept: none
The numbers are "x" and "y", therefore, we suggest this system of equations:
x-y=14
xy=1800
We can solve by substitution method.
x=14+y
(14+y)y=1800
14y+y²=1800
y²+14y-1800=0
Now, we solve this square equation:
y=[-14⁺₋√(196+7200)] / 2=(-14⁺₋86)/2
We have two solutions:
y₁=(-14-86)/2=-50 ⇒x=14+y=14-50=-36
y₂=(-14+86)/2=36 ⇒x=14+y=14+36=50
Answer: we have two solutions:
Solution1: The first number is -36 and the other number is -50
Soltuion2: The first number is 50 and the other number is 36

Answer:
Step-by-step explanation:
The area of a circular sector with a central angle θ and radius r is given by:
<em>Note</em>: The angle must be in radians.
We need to find both the radius and the angle in radians.
Diameter = 9.6 cm
Radius r=Diameter/2=4.8 cm
Angle in radians= Angle in degrees*π / 180
θ = 140*π / 180 = 2.4435 rad
Now we calculate the area:
