Congruent segments are simply line segments that are equal in length. Congruent means equal. Congruent line segments are usually indicated by drawing the same amount of little tic lines in the middle of the segments, perpendicular to the segments
Step-by-step explanation:
I'm assuming the given function is f(x) = 15x^2 + 10x.
If so, then,
f(x) = 15x^2 + 10x
f(x) = 15*(x)^2 + 10*(x)
f(-1) = 15*(-1)^2 + 10*(-1) ... note how x is replaced with -1
f(-1) = 15*(1) + 10*(-1)
f(-1) = 15 - 10
f(-1) = 5
Therefore the answer is 5
Answer:
5 minutes
Step-by-step explanation:
To get the response to this question, it would be required to convert both times to seconds alone.
For the first, the time It takes to flash is 1 minute 15 seconds which is same as 75 seconds
For the second, it takes 1 minute 40 seconds which is same as 100 seconds.
Now to get the time they would flash together, we need to know their lowest common multiples. The values involved are 75 and 100. Thus, the lowest common multiple of both is 300.
This is equivalent to 300 seconds which is 5 minutes time
