C is the answer i just did this answer and get it correct
100,000 equals 10 to the power of 5, hope helps.
now in a kite, the ∡x and the angle on the opposite side are twins.
the sum of all interior angles in a polygon are 180(n - 2), n = number of sides.
so a kite is a quadrilateral, 4 sides, so its interior angles add up to 180( 4 - 2) = 360°.
we know one side is 26°, and the opposite side is 90°, so the slack is 360 - 26 - 90 = 244°.
so the twins will take half each of that, namely each one takes 244/2 = 122° = ∡x.
f(x) = 2(x^2 + 14x + ) - 5 2 is taken out of first 2 terms.
f(x) = 2(x^2 + 14x + (14/2)^2 ) - 5 - 2(14/2)^2
<em><u>2 steps </u></em>
- Inside the brackets: Linear term's coefficient (14) divided by 2 and squared
- Outside the brackets: (14/2)^2 multiplied by 2 and subtract so that there is no change in the value of the quadratic.
f(x) = 2*(x + 7)^2 - 103
The graph is of the original quadratic.
