Answer:
Therefore the latitude closest to the equator is 6.49°(approx).
Step-by-step explanation:
Given the path of a solar ellipse is modeled by
![f(t)=0.00223t^2-0.558t+41.395](https://tex.z-dn.net/?f=f%28t%29%3D0.00223t%5E2-0.558t%2B41.395)
where f(t) is the latitude in degrees south of the equator at t minutes.
We know that ,
The minimum or maximum value of a function y(t) =at²+bt+c
is when ![t=-\frac{b}{2a}](https://tex.z-dn.net/?f=t%3D-%5Cfrac%7Bb%7D%7B2a%7D)
In this case a= 0.00223, b= - 0.558 and c= 41.395.
The minimum value of f(t)
when
=125.11
Therefore the latitude closest to the equator is
f(125.11)=0.00223(125.11)²-0.558×125.11+41.395
≈6.49
be x the tax for sale, then
X = ($ 14,05* )*0,06 = $0,843
The price of the item is
$14,05+ x , $14,05 + 0.843 = $14,893
The correct answer will be 200 hope this helpsss
Answer:
m
Step-by-step explanation:
The formula to find the area of a rectangle:
, where
is the length and
is the breadth.
1) Substitute the values into the formula.
2) Change it to an improper fraction and solve for
.
![\frac{63}{5} = \frac{20}{3} * b](https://tex.z-dn.net/?f=%5Cfrac%7B63%7D%7B5%7D%20%3D%20%5Cfrac%7B20%7D%7B3%7D%20%2A%20b)
*
=
![\frac{189}{100} = b](https://tex.z-dn.net/?f=%5Cfrac%7B189%7D%7B100%7D%20%3D%20b)
3) Change it to a mixed fraction because the length is in a mixed fraction. To do it, do a long division.
= ![1\frac{89}{100}](https://tex.z-dn.net/?f=1%5Cfrac%7B89%7D%7B100%7D)
