Answer: Our required answer is 0.08%.
Step-by-step explanation:
According to U.S., if anyone has consumed 0.08 % or above , then he will considered as legally impaired, and he would be administratively suspended.
If he has a breath or blood alcohol level of 0.08% or above or refuse to submit to a chemical test.
In U.S. it must be less than 0.08% in blood alcohol concentration.
Hence, our required answer is 0.08%.
Answer: 6.4 degrees
Step-by-step explanation:
a= 5 degrees temperature difference to the north gives the opposite of the triangle,
b = 4 degrees temperature difference to the west gives the adjacent,
c = temperature difference of 1 mile to the south east gives the hypotenuse.
Therefore,
Using Pythagoras equation,
c² = b² + a²
c = sqrt( 5² + 4²)
c = sqrt(41) = 6.4 degrees
Therefore, there will be 6.4 degrees temperature difference 1 mile to the south east
The initial deceleration is 4 m/s^2, so this means that considering the first line segment,
.
The total distance traveled is 4 km, which is equal to 4000 meters. This is equal to the area under the graph, so
.
![400(100-4T)-\frac{1}{2}(4T)(5T)=4000\\\\40000-1600T-10T^2=4000\\\\10T^2 +1600T-36000=0\\\\T^2 +160T-3600=0\\\\(T+180)(T-20)=0\\\\T=20 (T > 0)\\\\\therefore V=100-4(20)=20](https://tex.z-dn.net/?f=400%28100-4T%29-%5Cfrac%7B1%7D%7B2%7D%284T%29%285T%29%3D4000%5C%5C%5C%5C40000-1600T-10T%5E2%3D4000%5C%5C%5C%5C10T%5E2%20%2B1600T-36000%3D0%5C%5C%5C%5CT%5E2%20%2B160T-3600%3D0%5C%5C%5C%5C%28T%2B180%29%28T-20%29%3D0%5C%5C%5C%5CT%3D20%20%28T%20%3E%200%29%5C%5C%5C%5C%5Ctherefore%20V%3D100-4%2820%29%3D20)
F(-2) = 40
f(-1) = 16
f(0) = 6
f(1) = 10
f(2) = 28
Tang i think hope it is right
