You were supposed to find the area of the darkened area
Answer:
28 units
Step-by-step explanation:
ABCD is a rectangle. AC and BD are diagonals intersecting at point E.
Diagonals of a rectangle bisect each other.
(diagonals of a are equal in measure)
![\therefore AC = 28\: units](https://tex.z-dn.net/?f=%20%5Ctherefore%20AC%20%3D%2028%5C%3A%20units%20)
Answer:
Nathan weighs 12 more pounds than Marty.
Step-by-step explanation:
If Marty weighs 64 pounds and Nathan weighs 76 pounds, we can subtract the weight of Marty from Nathan to get our answer.
![76-64=12](https://tex.z-dn.net/?f=76-64%3D12)
In case Nathan was actually 476 pounds, the answer would be 412.
Answer:
5.4 hours
Step-by-step explanation:
As the number of hours of daylight y is modeled as a function of sin, and sin has the minimum value of -1. Therefore
![sin(2\pi 365x-1.4) \geq -1](https://tex.z-dn.net/?f=sin%282%5Cpi%20365x-1.4%29%20%5Cgeq%20-1)
![7sin(2\pi 365x-1.4) \geq -7](https://tex.z-dn.net/?f=7sin%282%5Cpi%20365x-1.4%29%20%5Cgeq%20-7)
![7.0sin(2\pi 365x-1.4)+12.4 \geq 5.4](https://tex.z-dn.net/?f=7.0sin%282%5Cpi%20365x-1.4%29%2B12.4%20%5Cgeq%205.4)
![y \geq 5.4](https://tex.z-dn.net/?f=y%20%5Cgeq%205.4)
So the minimum number of hours of daylight in Anchorage is 5.4 hours
