Answer:
7 degrees
Step-by-step explanation:
The temperature in Monday was 14 degrees
On tuesday the temperature decreased by 5 degrees
On Wednesday it decreased by 10 degrees
On thursday the temperature increased by 8 degrees
Therefore the temperature at the end of the day on Thursday can be calculated as follows
= 14 - 5 - 10 + 8
= 7
Hence the temperature at the end of the day on Thursday is 7 degrees
Answer:
The answer to your question is dAC = 10 units
Step-by-step explanation:
Data
From the graph, take the coordinates of the points A and C.
A (3, - 1)
C (-5, 5)
Process
Use the formula of the distance between two points to find the length
d = ![\sqrt{(x2 - x1)^{2} + (y2 - y1)^{2}}](https://tex.z-dn.net/?f=%5Csqrt%7B%28x2%20-%20x1%29%5E%7B2%7D%20%2B%20%28y2%20-%20y1%29%5E%7B2%7D%7D)
x1 = 3 y1 = -1
x2 = -5 y2 = 5
Substitution
dAC = ![\sqrt{(-5 - 3)^{2} + (5 + 1)^{2}}](https://tex.z-dn.net/?f=%5Csqrt%7B%28-5%20-%203%29%5E%7B2%7D%20%2B%20%285%20%20%2B%201%29%5E%7B2%7D%7D)
Simplification
dAC = ![\sqrt{(-8)^{2} + (6)^{2}}](https://tex.z-dn.net/?f=%5Csqrt%7B%28-8%29%5E%7B2%7D%20%2B%20%286%29%5E%7B2%7D%7D)
dAC = ![\sqrt{64 + 36}](https://tex.z-dn.net/?f=%5Csqrt%7B64%20%2B%2036%7D)
dAC = ![\sqrt{100}](https://tex.z-dn.net/?f=%5Csqrt%7B100%7D)
dAC = 10 units
