What is the e at the end of a scientific number?

1 answer:

6 0

Scientific notation is another way to write a number. In scientific notation, the letter E is used to mean "10 to the power of." For example, 1.314E+1 means 1.314 * 101 which is 13.14 .

Answer:

? = 9

Step-by-step explanation:

The segments of each of the transversals are proportional. On the left side, the bottom transversal segment will be 10 -6 = 4 units in length.

Now we can write a proportion relating right-side transversal segments to left-side transversal segments:

?/6 = 6/4

? = 6(6/4) = 36/4 = 9

The missing length is 9 units.

50 POINTS!! Please please help find height and volume of pyramid!!!

masya89 [10]

Answer:

$v=4468.8m^{3}$

$h=17.1$

Step-by-step explanation:

$B=28^{2}$

$B=784$

$h=\sqrt{(22.1)^{2} -(14)^{2} } \\$

$h=17.1$

$v=1/3Bh$

$1/3(784)(17.1)$

$v=4468.8m^{3}$

$-----------$

hope it helps..

have a great day!!

A student said that x = 4 was not a solution to the question 3(x -6) = -8

Morgarella [4.7K]

Answer:

Step-by-step explanation:

3 (4 -6) = -8 is correct. The next step is to combine 4 and -6, obtaining

3(-2)

and this 3(-2) should equal -6, which is not the same as -8.

3(4 - 6) = 12 - 18, which differs from the student's solution. This is the reason for the wrong answer.

LAST ATTEMPT MARKING AS BRAINLIEST!! ( graph the image of the figure using the dilation given)

Natali5045456 [20]

<h3>Answers:</h3>

$W(-2,-1) \to \\W \ ' \ (-4,4)\\\\X(0,2) \to \\X \ ' \ (0,4)\\\\Y(3,-1) \to \\Y \ ' \ (6,-2)\\\\V(-2,-1) \to \\V \ ' \ (-4,-2)\\\\$

=====================================================

Explanation:

The scale factor is 2, which means we double each coordinate of each point. The general rule is $(x,y) \to (kx,ky)$ with k = 2. So we can say the more specific dilation rule is $(x,y) \to (2x,2y)$

Something like W(-2,2) moves to W ' (-4, 4) after multiplying each coordinate by 2. Do the same for the other points as well.

The given preimage points

V = (-2, -1)
W = (-2, 2)
X = (0, 2)
Y = (3, -1)

will dilate to the corresponding image points

V ' = (-4, -2)
W ' = (-4, 4)
X ' = (0, 4)
Y ' = (6, -2)

as shown below. This causes the image to be larger compared to the preimage (since the scale factor is larger than 1). Any given point is twice as far from the origin as compared to before, which in turn means the distance between any two points is twice as much.
