Answer:
5.5 Meters below sea level
Step-by-step explanation:
Since sea level is at 0 meters, the girl is already 1 meter below sea level. When she dives down another 4.5 meters, you just add
1 + 4.5 = 5.5
and that's your answer
:)
60x0.25=15
60x0.10=6
51x0.25=12.75
13.35-12.75
D-6
Q-51
Unit rate is feet per 1 second
117/6.5=18/1=18ft per second
Answer: 28x-2
Step-by-step explanation:
First, you get rid of the parentheses. Since the symbol is +, nothing really changes: 12x - 3 + 16x +1
Then, you combine like terms to get your answer: 28x-2
First we need to convert the given equation to standard form, then we can write the center and radius directly from it.
![x^{2} -16x+ y^{2} -36=0 \\ \\ x^{2} -2(x)(8)+ y^{2} = 36 \\ \\ x^{2} -2(x)(8)+ 8^{2}+ y^{2} =36 +8^{2} \\ \\ (x-8)^{2}+y^{2}=100](https://tex.z-dn.net/?f=%20x%5E%7B2%7D%20-16x%2B%20y%5E%7B2%7D%20-36%3D0%20%5C%5C%20%20%5C%5C%20%0A%20x%5E%7B2%7D%20-2%28x%29%288%29%2B%20y%5E%7B2%7D%20%3D%2036%20%5C%5C%20%20%5C%5C%20%0A%20x%5E%7B2%7D%20-2%28x%29%288%29%2B%208%5E%7B2%7D%2B%20%20y%5E%7B2%7D%20%3D36%20%2B8%5E%7B2%7D%20%5C%5C%20%20%5C%5C%20%0A%28x-8%29%5E%7B2%7D%2By%5E%7B2%7D%3D100%20%20)
Thus, we can say now:
Center of the circle is (8,0) and its radius is 10.
