-7. When you look at the graph it is divided into x and f(x). f(x) is the same as y so the question is basically asking you what is x when y is -3. So you just go to the -3 under f(x) and look over to find that the answer is -7
Answer:
x = +-sqrt(3) and they are the actual solutions
Step-by-step explanation:
x^2/ (2x-6) = 9/(6x-18)
get a common denominator of 6x-18
x^2/ (2x-6) * 3/3 = 9/(6x-18)
3x^2/ (6x-18) = 9/(6x-18)
since the denominators are the same, the numerators must be the same
3x^2 = 9
divide by 3 on each side
x^2 = 3
take the square root of each side
sqrt(x^2) = +-sqrt(3)
x = +-sqrt(3)
To calculate time at t= 2 minutes. We substitute at t = 2.
h = 10.5 + 6.5 sin(850t)
h = 10.5 + 6.5 sin (850 * 2)
h = 10.5 - 6.4012 = 4.1 feet
Hence at time t = 2, height = 4.1 feet.
Answer:
154.8
Step-by-step explanation:
20% is equal to 20/100= 0.20. So, 0.20 multiplied by 129 will give you 20% of 129 which is 25.8. If Alan ran 20% more then you add 25.8 to 129 which gives you an answer of 154.8.
Equation: 20/100= 0.2
0.2* 129= 25.8
25.8+129= 154.8
Alan ran 154.8 laps.
