Y=-x squared - 6x -5 what is the vertex and x-intercepts

Alenkasestr [34]

$y=-x ^2 - 6x -5 \\ \\ standard \ form \\ \\y=ax+bx+c \\ \\V(p,q)\\ \\ p=\frac{-b}{2a}=\frac{-(-6)}{-2}=3\\ \\\Delta = b^{2}-4ac =14^{2}-4*1*(-51)=196+204=400 \\ \\q=\frac{-\Delta }{4a} =\frac{-400}{4}=100\\ \\V( 3,100)\\ \\x_{1}=\frac{-b-\sqrt{\Delta }}{2a} =\frac{-14- \sqrt{400}}{2}=\frac{-14-20}{2}= \frac{-34}{2}=-17\\ \\x_{2}=\frac{-b+\sqrt{\Delta }}{2a} =\frac{-14+ \sqrt{400}}{2}=\frac{-14+20}{2}= \frac{6}{2}=3$

What is the measure of angle A? What is the measure of angle B?

Anettt [7]

Answer:So, if there is a right angle and it is split into two unequal angles, then you may be able to determine its measurement since one angle is measured. The size of one aspect is thirty-two degrees. Therefore, ninety minus thirty-two is fifty-eight degrees. So, angle b is fifty-eight degrees.
