The lowest elevation in Lammefjord, Denmark, is 23 feet below sea level. The elevation of the Sea of Galilee in Israel is about

tatyana61 [14]

Answer:

$Sea\ of\ Galilee = -690ft$

Step-by-step explanation:

Given

$Lowest\ Elevation = 23ft$ below sea level

Sea of Galilee = 30 times Lowest in Lammefjord, Denmark

Required

Determine the elevation of the Sea of Galilee

We have that the lowest elevation in Lammefjord is:

$Lowest\ Elevation = -23ft$

It is negative because, the elevation is below sea level.

Calculating the elevation of Sea of Galilee, we have:

Sea of Galilee = 30 times Lowest in Lammefjord, Denmark

$Sea\ of\ Galilee = 30 * -23ft$

$Sea\ of\ Galilee = -690ft$

<em>Hence, the elevation of Sea of Galilee is -690ft or 690ft below sea level</em>

Vlad [161]

Answer:

The attached image shows the graph for the given function.

Step-by-step explanation:

We are given the following function in the question:

$y(x) = 2^{x-1}$

We have to graph the given function.

Properties of the given function are:

It is an exponential function of the form $y(x) = a^{x + b}$
Here, a = 2, b = -1
The y-intercept of the given function is (0,0.5)
There is no x-intercept.
The domain of the given function is all real numbers.
The range of given function is $(0,\infty)$

The attached image shows the graph for the given function.

When deriving the quadratic formula by completing the square, what expression can be added to both sides of the

liubo4ka [24]

Answer:

The element you add is $b^2 / 4a$

Step-by-step explanation:

The element you add is $b^2 / 4a$

Remember that

$a x^2 + bx +c \\= a ( x^2 +(b/a)x ) + c$

So, in order to complete the square you add $(b/2a)^2$

But when you multiply times $a$ you get

$b^2 / 4a$

Which correctly describes a cross section of the cube below? Check all that apply.

dmitriy555 [2]

Answer:

A cross section parallel to the base is a square measuring 4 cm by 4 cm.

A cross section perpendicular to the base through the midpoints of opposite sides is a square measuring 4 cm by 4 cm.

A cross section that passes through the entire bottom front edge and the entire top back edge is a rectangle measuring 4 cm by greater than 4 cm.

Step-by-step explanation:

Cross sections parallel and Perpendicular to the base are squares 4 × 4

The diagonal cross section will be a rectangle with base 4 and height

sqrt(4² + 4²) = 4sqrt(2) > 4
