How many significant figures will be in the answer when you multiply 3.4 x 4.56?

1 answer:

6 0

There are 2 before the decimal point because 3×4=12 and 12 has two digits.
There are 3 after the decimal point because we add together the number of digits after the decimal point in the operands, which is 1 plus 2=3. In all then there are 2+3=5 significant figures.

an engineer decides to use similar triangles to find the distance across the river she makes the diagram below which triangles t

sergiy2304 [10]

<h2>Explanation:</h2><h2 />

The missing diagram is shown below. Remember that shapes are similar if you can turn one into the other by moving, rotating, flipping, or scaling. So this means you can make the object bigger or smaller. So in this case, we know that ΔABC is similar to ΔDEF. If so, we can establish the following proportion:

$\frac{h}{56.7}=\frac{17.2}{52.4} \\ \\ h=56.7\times \frac{17.2}{52.4} \\ \\ h=18.61m$

Our goal is to find x. So by Pythagorean theorem:

$x=\sqrt{17.2^2+18.61^2} \\ \\ \boxed{x=25.34m}$

Conclusion:

<em>Distance across the river is 25.34m </em>

Monomial is one term, like #2 would be a monomial. binomial is two terms, like 3x - 2. trinomial is three terms, like #1,3,4. polynomial is four terms, like #5. standard form is just rewriting the equation in order from the term with the highest exponent to the lowest
