The complex solutions come in pairs and the only difference between them is the sign between the real and imaginary part, so one of the other two solutions is 2+3i. The third solution can be easily found using the rational root theorem, and it's equal to -1.

If my heart beats 2790 times every three quarters of an hour, what is your heart rate per minute?
kodGreya [7K]

Your heart rate is the number of times each minute that your heart beats, which is normally between 60 and 100 times per minute for adults. Your pulse is a way you can feel each time your heart beats. Measuring your heart rate helps you monitor your own health and know if you’re exercising at the right level to get the most benefits to your health.

Your pulse is your heart rate, or the number of times your heart beats in one minute. Pulse rates vary from person to person. Your pulse is lower when you are at rest and increases when you exercise (more oxygen-rich blood is needed by the body when you exercise). Knowing how to take your pulse can help you evaluate your exercise program.

X: y = 1:5 Which is the correct equation? A y = 5x By= C y=x-4 D y=x+4
Ymorist [56]
The answer should be A. For example, if x = 1, and the ratio between x and y is y is 5 times greater than x, then y would equal 5, which is only true in A.

Or, use the number 5 as an example. If x = 5, and the ratio between x and y is y is 5 times greater than x, then y is 5.

And if you put that into A, y = 5x, it becomes 25 = 5(5)
Then 25 = 25, which is true!
