Answer:
There are a total of 2 hours and 50 min.
Step-by-step explanation:
1 hour = 60 min
60 x 2 = 120 min
60 x 3 = 180 min - too much
so take away 10 from 180 min to get 170
Of the provided graphs, the second would be the correct answer.
Functions occur when the input only has one possible output (though the output can be recieved through multiple inputs)
Answer:
3.14
Step-by-step explanation:
radius*pi
21/4=12\7:x
21 se simplifică cu 7 și o să ne dea 3
și 1
12 se simplifică cu 4 și o să ne dea
3 și 1
3\1=3\1:x
x=3x3
x=9
The x intrercepts is where the function crosses the x axis; In other words, it is where the output of the function is 0.
In a quadratic, you can start by factoring, if it’s unable to be factored then use the quadratic formula. Also, it is good to use the discriminate.
D= Discrimminate
D>0 2 real solutions
D=0 1 real solution
D<0 2 imaginary solutions.
The discrimminate is the equation/expression under the radical of the quadratic formula. With this formula, it’s not factorable. Using the discriminate it is also seen, as you’ll get a negative in the square root. This is imagenary because you cannot take the root of a negative value, which is why “i” is used to represent the square root of negative one.
