Elina [12.6K]

Answer:

Two solutions: -0.12 and 1.75.

Step-by-step explanation:

The quadratic formula is:

$\begin{array}{*{20}c} {\frac{{ - b \pm \sqrt {b^2 - 4ac} }}{{2a}}} \end{array}$ . Assuming that the x² term is a, the x term is b, and the constant is c, we can plug the values into the equation.

$\begin{array}{*{20}c}{\frac{{ - 8 \pm \sqrt {8^2 - 4\cdot-4.9\cdot1} }}{{2\cdot-4.9}}} \end{array}$

$\begin{array}{*{20}c}{\frac{{ - 8 \pm \sqrt {64 + 19.6} }}{{-9.8}}} \end{array}$

$\begin{array}{*{20}c}{\frac{{ - 8 \pm \sqrt {83.6} }}{{-9.8}}} \end{array}$

$\begin{array}{*{20}c}{\frac{{ - 8 \pm \sqrt {9.14} }}{{-9.8}}} \end{array}$

$\frac{-8 + 9.14}{-9.8} = -0.12$

$\frac{-8-9.14}{-9.8} =1.75$

Hope this helped!

What is the length of side EF in the triangle? Please give a step by step explanation, I'm having lots of trouble finding the so

wel

Answer:

EF = 8.8 cm

Step-by-step explanation:

In the given right angled ΔDEF, DE is the hypotenuse while EF and DF are adjacent sides. So that applying the Pythagoras theorem, we have;

$/hyp/^{2}$ = $/adj1/^{2}$ + $/adj2/^{2}$

$/DE/^{2}$ = $/EF/^{2}$ + $/DF/^{2}$

$/16.2/^{2}$ = $/EF/^{2}$ + $/13.6/^{2}$

262.44 = $/EF/^{2}$ + 184.96

$/EF/^{2}$ = 262.44 - 184.96

= 77.48

EF = $\sqrt{77.48}$

= 8.8023

EF = 8.8 cm

The length of side EF is 8.8 cm.
