How should the number 1.230 x 103 be properly expressed as a decimal?

1 answer:

4 0

Answer: 1,230
Usage of 10^x form is called scientific form and it helps much in science where the calculation unit can vary from very big into very small.
In this case, you are given the number 1.230 x 10^3 and asked to express it in decimal form. Then you just simply need to multiply the number with the 10^3. The calculation would be: 1.230 x 10^3= 1.230 x 1000= 1230

Find the missing side of the triangle. Round your answers to the nearest tenth if necessary.

Alik [6]

Given:

In a right angle triangle, the measures of two legs are 5 ft and 5.6 ft. The measure of the hypotenuse is x.

To find:

The value of x.

Solution:

Pythagoras theorem: In a right angle triangle,

$(Hypotenuse)^2=(Base)^2+(Perpendicular)^2$

Using Pythagoras theorem, we get

$(x)^2=(5)^2+(5.6)^2$

$x^2=25+31.36$

$x^2=56.36$

Taking square root on both sides, we get

$x=\sqrt{56.36}$

$x=7.50733$

$x\approx 7.5$

The measure of missing side is 7.5 ft. Therefore, the correct option is D.

Please help with the attached! Thanks!!

Kisachek [45]

Rate of change of [1,3] is $\frac{15.882-11.38}{3-1} = \frac{4.502}{2} =22.51$
Rate of change of [-4, -2] is $\frac{.0971-.0018}{-3--4} = \frac{.0953}{1}=.0953$
The difference between them is 22.51-.0953=22.4147

Hope that helps
