Answer:

Acute, Right and Obtuse

Step-by-step explanation:

The first triangle is Acute because all the angles are less the 90 degrees.

The second triangle is Right because there is a 90 degree angle in it. A Right Angle is marked with a square in the corner.

The last is Obtuse because there is one angle that is greater than 90 degrees.

The value of y varies directly with x, and y = 48 when x = 16. Find y when x = 176.

emmainna [20.7K]

Try to find what y is when x is equal to one.

48/16= 3

So, when x is 1, y is 3.

(1,3)

All you need to do is multiply 176 by 3 for the correct value of y.

176*3= 528

When x= 176, y= 528. (176,528)

I hope this helps!

Answer:

$\bold{x_1=-\dfrac{3+\sqrt{41}}{2}\approx-4.7\ ,\quad x_2=-\dfrac{3-\sqrt{41}}{2}\approx1.7}$

Step-by-step explanation:

$-2x^2-3x+4=0\\\\a=-2\,,\ b=-3\,,\ c=4\\\\\\x=\dfrac{-b-\sqrt{b^2\pm4ac}}{2a}=\dfrac{-(-3)\pm\sqrt{(-3)^2-4(-2)(4)}}{2(-1)}=\dfrac{3\pm\sqrt{9+32}}{-2}\\\\\\x_1=-\dfrac{3+\sqrt{41}}{2}\approx-4.7\ ,\qquad x_2=-\dfrac{3-\sqrt{41}}{2}\approx1.7$
