Answer:
The population size after four days is calculated as 168.
Step-by-step explanation:
Let the population size be P
t be the time variable which is measured in hours
Therefore,
by the differential equation
= 0.8329P
So,by solving and expifying the equation on both sides, we get
P = Ae^0.8329t
Therefore,from the first equation we get
P(0) = 6,
A = 6.
Therefore the population size after four days is
P(4) =
= 168( rounded to nearest whole number)
Answer:
$3 discount
Step-by-step explanation:
If Fredo originally had the markdown as $0 (meaning no change), then he arrived at the store, seeing the markdown was $2, the current markdown is $2.
Now that he has an extra $1 off, he gets 2+1 = $3 off the bread.
Hope this helped!
Answer:

Step-by-step explanation:
i) The diameter of the circle is B,C.
Answer:
1231 ft
Step-by-step explanation:
Draw a right triangle. Label the height of the triangle. as 800 since the height of the triangle represents the height of the helicopter above the coast of the island. Label the base length of the triangle as d to represent the distance between the coast of the island and the coast of the mainland, P. The angle of depression from the helicopter to point P is 33° so draw a horizontal dotted line at the location of the helicopter and label the angle made by the horizontal line and the hypotenuse of the right triangle as 33°. The angle of elevation from P to the helicopter and the angle of depression from the helicopter to point P are congruent alternate interior angles so label the angle at P as 33°.
The side labeled 800 is opposite of P and the side labeled d is adjacent to P so you can use tangent to write an equation. Solve this equation for d and round to the nearest whole number.
The missing options that makes up the distance formula between two coordinates are; (x₂ - x₁)² and d²
How to find the distance between two coordinates?
The formula for distance between two coordinates is;
d = √[(y₂ - y₁)² + (x₂ - x₁)²]
where;
(x₁, y₁) is the coordinate of the first point
(x₂, y₂) is the coordinate of the second point
Now, this distance formula can also be rewritten when we square both sides to get;
(y₂ - y₁)² + (x₂ - x₁)² = d²
Thus, the missing options that makes up the distance formula between two coordinates are; (x₂ - x₁)² and d²
