Answer:

63°

Step-by-step explanation:

$m\angle BKD =\frac{1}{2}(m\widehat {AE} +m\widehat {BD} )$

$\implies m\angle BKD =\frac{1}{2}(86\degree +40\degree)$

$\implies m\angle BKD =\frac{1}{2}(126\degree)$

$\implies m\angle BKD =63\degree$

Rewrite the function by completing the square.<br> f(x) = x2 – 10x + 44<br> +<br> f(x) = (x+

iVinArrow [24]

Answer:

$f(x)=(x-5)^{2}+19$

Step-by-step explanation:

we have

$f(x)=x^{2}-10x+44$

Group terms that contain the same variable, and move the constant to the opposite side of the equation

$f(x)-44=x^{2}-10x$

Complete the square. Remember to balance the equation by adding the same constants to each side.

$f(x)-44+25=x^{2}-10x+25$

$f(x)-19=x^{2}-10x+25$

Rewrite as perfect squares

$f(x)-19=(x-5)^{2}$

$f(x)=(x-5)^{2}+19$

If one class collected 65 cans for the food drive and another class collected 176 cans, how many cans did the two classes collec

kotegsom [21]

In this equation C means the total. In order to find the total you must add the two class together to get the total. The equation that represents this would be the fourth one. 65 + 176 = C
