Y=-3x^2+6x+c; (1,0) find C
kogti [31]
<span>Simplifying 3x2 + -6x + c = 0 Reorder the terms: c + -6x + 3x2 = 0 Solving c + -6x + 3x2 = 0 Solving for variable 'c'. Move all terms containing c to the left, all other terms to the right. Add '6x' to each side of the equation. c + -6x + 6x + 3x2 = 0 + 6x Combine like terms: -6x + 6x = 0 c + 0 + 3x2 = 0 + 6x c + 3x2 = 0 + 6x Remove the zero: c + 3x2 = 6x Add '-3x2' to each side of the equation. c + 3x2 + -3x2 = 6x + -3x2 Combine like terms: 3x2 + -3x2 = 0 c + 0 = 6x + -3x2 c = 6x + -3x2 Simplifying c = 6x + -3x<span>2</span></span>

7.For the given triangle find the exact value for tan(A). Assume angle C is a right angle.
Vsevolod [243]

tan A = 2/7 (option C)

Explanation:

Angle = A

opposite = side opposite the angle = BC

opposite = 2

adjacent = AC

AC = 7

hypotenuse not given

Since angle C is a right angle, we would apply trigonometry ratio SOHCAHTOA

We are looking for tan A, tan ratio (TOA):

\tan angle=\frac{opposite}{adjacent}\tan \text{ A = }\frac{2}{7}\text{ (}option\text{ C)}
