Answer:
m<R = 31°
Step-by-step explanation:
Arc QT = 39°
Arc PV = 101°
m<R = ½(arc PV - arc QT) => secant-secant exterior angle measure theorem
m<R = ½(101 - 39)
m<R = ½(62°)
m<R = 31°
The number y, decreased by 12
Step-by-step explanation:
22x13, 10x9, then both answers from the previous equations multiplied. Any questions?
Hey there!
To find the discriminant of an equation, you first need to identify the A, B, and C of your equation. You can do this by comparing your equation to the standard form.
Standard Form: ax² + bx + c
Equation: 3x² – 10x + 2
If you add 2 to both sides, you can get everything on one side and you can assure that all of your numbers are accurate.
A will be equal to 3, B will be –10, and C will be 2.
Now, you need to plug in those numbers into the discriminant equation:
b² – 4ac
If your discriminant is 0, there is one rational solution. If it's a positive perfect square, there are 2 rational solutions. If it's a positive non–perfect square, there will be 2 irrational solutions, and if it's a negative number, there will be 2 complex solutions.
Hope this helped you out! :-)
Well, it says that 34 kids like physics and since there is 100 students, we know 34% of the kids like physics. This means 66% like biology.
