What you need to know for this case is that the calculator is using the scientific notation in two different ways:

Way 1:

a * 10 ^ b

Way 2:

aeb

Where, in both cases:

a, b: they are real numbers.

Therefore, for the following number:

 1.89*10^{-12}

We have an equivalent way is:

1.89e-12

Answer:

1.89e-12

The e refers to the exponent to which the base 10 is elevated.

Answer:

1.89\times 10^{-12}=1.89e-12

Step-by-step explanation:

Given : A graphing calculator displays 1.89\times 10^{12} as 1.89e12.

To find : How do you think it would display 1.89\times 10^{-12}? What does the e stand for?

Solution :

In a graphing calculator 'e' stand for exponent of 10.

1.89\times 10^{12}=1.89e12

In 1.89\times 10^{-12} there is only negative sign difference.

So, 1.89\times 10^{-12}=1.89e-12

PLEASE HELP!!!! The two points shown below (-2,-4) (3,-4)are reflected across the x-axis. Then, the four points are connected to
Allisa [31]

Answer:

26 units

Step-by-step explanation:

Transformation is the movement of a point from its initial location to a new location. Types of transformation are reflection, rotation, dilation and reflection.

If a point A(x, y) is reflected across the y axis, the new point is A'(x, -y).

The reflection of the point (-2,-4) across the x axis gives (-2, 4) while the reflection of (3, -4) gives (3, 4)

The distance between (-2, -4) and (-2, 4) is the length while from (-2, -4) to (3, -4) is the breath. Hence:

Lengthth=\sqrt{(-2-(-2))^2+(-4-4)^2}=\sqrt{64}=8\\  \\Breadth=\sqrt{(-2-3)^2+(-4-(-4))^2}=\sqrt{25}=5

Perimeter of rectangle = 2(length + breath) = 2(8 + 5) = 2(13) = 26 units

A submarine rises a vertical distance of 200 m to the surface. The distance measured along the submarine's path is 500 m.
postnew [5]

Answer:

24°

Step-by-step explanation:

Oh, okay. So this is like (kinda?) the opposite of what I did in the last one. This time, instead of finding the side length of the imaginary triangle, you are trying to find the angle of elevation (that's what I call it)

sin θ = 200/500

θ = sin^-1 (200/500)

θ = 23.578...

Rounded:

θ = 24°
