D - Add, Subtract, Multiply, and Divide Integer A submarine Is at a depth of 350 feet below sea level. It makes the following mo

Westkost [7]

We have the next information

A submarine Is at a depth of 350 feet below sea level means -350

First, it goes down 150 feet. means -150

Next, it goes up 132 feet. means +132

Then, it goes down 179 feet. means -179

Finally, it goes down 145 feet means -145

then we have the next operations

-350+(-150)+132+(-179)+(-145)=-692

The sing minus means that It is below the sea level

therefore the correct choice is

A It is 692 feet below sea level, because -350 + (-150) + 132 + (-179) + (-145) = -692.

The Quadratic Formula 7:Solving Quadratic Equations

Margaret [11]

Answer:

B. 1.14, -0.77

Step-by-step explanation:

As you know the quadratic formula gives you the solution to

ax² + bx + c = 0

as ...

$x=\dfrac{-b\pm\sqrt{b^2-4ac}}{2a}$

Here, we have a=8, b=-3, c=-7, so the formula tells us the solution is ...

$x=\dfrac{-(-3)\pm\sqrt{(-3)^2-4(8)(-7)}}{2(8)}=\dfrac{3\pm\sqrt{233}}{16}\\\\x\approx \{-0.7665,1.1415\} \qquad\text{matches choice B}$
