Answer:
Step-by-step explanation:
Given that,
The arc length is four times the radius
Let he radius be 'r'
Then, the arc length be 's'
The arc of a sector can be calculated using
s=θ/360 × 2πr
Then, given that s=4r
So, 4r = θ × 2πr / 360
Divide both side r
4 = θ × 2π/360
Then, make θ subject of formula
θ × 2π = 360 × 4
θ = 360 × 4 / 2π
θ = 720 / π
So, area of the sector can be determine using
A = θ / 360 × πr²
Since r = ¼s
Then,
A = (θ/360) × π × (¼s)²
A = (θ/360) × π × (s²/16)
A = θ × π × s² / 360 × 16
Since θ = 720 / π
A = (720/π) × π × s² / 360 × 16
A = 720 × π × s² / 360 × 16 × π
A = s² / 8
Then,
s² = 8A
Then,
s= √(8A)
s = 2 √2•A
Answer:
$654.98
Around 7.7 years
Step-by-step explanation:
Value = P × e^(rt)
= 500 × e^(0.09×3)
= 500 × e^(0.27)
= 654.9822254
Double: 500 × 2 = 1000
1000 = 500 × e^(0.09t)
e^(0.09t) = 2
Use ln both sides
0.09t × lne = ln2
t = ln2 ÷ 0.09
t = 7.70163543

A Cosine ratio is the hypotenuse in a right triangle is always larger than the adjacent side, so for angles greater than zero but less than 90º the cosine ratio will be less than . and the Secant ratio<span> there are three other trigonometric functions you need to know for the Math IIC: cosecant,</span>secant<span>, and cotangent.</span>
