10. What makes an equation a quadratic?
CaHeK987 [17]

Answer:

D. The equation has a variable multiplied by itself. A squared variable.

Step-by-step explanation:

A quadratic equation will always start with a term being squared. For example, 8x^{2} + 5x + 7 = 44. Another example would be 4x^{2} + 2x - 10 = 12. These are just random numbers, but the equation will always look the same! Hope this helps!

Is the relation shown in the arrow diagram a function?
Irina-Kira [14]

Answer:

Yes. Every unique input has a unique output.

Step-by-step explanation:

Since every input has a different output, therefore it's a function. It's not a function when the input have more than 1 output. When graphing, make sure you take the vertical line test to see whether or not the graph is a function.

DOES ANYONE KNOW THE ANSWERS TO THESE PROBLEM, PLZ HELP!
Virty [35]

Answer:

Q.1.

Sum of angles of a triangle = 180°

∠A + ∠B + ∠c = 180

(3x - 9) + (4x + 15) + 90 = 180

3x - 9 + 4x + 15 + 90 = 180

7x + 96 = 180

7x = 84

x = 12

∠A = 3x - 9 = 3(12) - 9 = 36 - 9 = 27°

∠B = 4x + 15 = 4(12) + 15 = 48 + 15 = 63°

∠A = 27°

∠B = 63°

Q.2.

using \ pythagoras \ theorem \\x^2 = 7^2 + (7\sqrt{3} )^{2} = 49  + 49(3) = 196\\x = \sqrt{196}  = 14

sin y = \frac{opposite}{hypotenuse} = \frac{7\sqrt{3} }{14}   = \frac{\sqrt{3} }{2} \\\\y = sin^{-1} (\frac{\sqrt{3} }{2} ) = 60

x = 14

y = 60°
