Estimation is useful to quickly compute a value without needing a calculator. This way you can get a sense of scale of a project. Of course, when it comes time to doing the actual project, you should compute more accurate values to avoid rounding error.

---------------

For example:

2.3*5.7 estimates to 2*5 = 10

The actual value is 2.3*5.7 = 13.11; we see the estimate 10 is an underestimate. The estimate isn't too far off, so we get a sense of the size/scale of this product.

Find the GCF<br> 50x^4, -10x^5, 2x^6
shtirl [24]

Answer:

2 x^4

Step-by-step explanation:

Recall that the GCF is the greatest of the product of factors that are common to all these three expressions

then for the pure numerical part, the factor common to 50, -10 , and 2 is "2"

and for the variable part x^4 is the largest common to all three expressions.

Therefore the GCF is: 2 x^4

F (x) = |x + 3| -1 . Find the average rate of change from x = -6 to x = 8
Elenna [48]
Average rate of change is (f(8) - f(-6))/(8 - (-6)) = ((<span>|8 + 3| -1) - (</span><span>|-6 + 3| -1))/(8 + 6) = ((</span><span>|11| -1) - (</span><span>|-3| -1))/14 = ((11 - 1) - (3 - 1))/14 = (10 - 2)/14 = 8/14 = 4/7</span>

Cross-multiplication is helpful in: a. quadratic equations c. linear equations b. solving proportions d. word problems
Romashka [77]

Answer:

Cross multiplying fractions helps us to see if numbers are equal, and if not, which is bigger and which is smaller. But that is not its only use. Cross multiplying fractions can help us to solve for unknown variables in fractions.

Suppose ray AT bisects Angle CAR. If the measure of Angle CAT is 5x, and
Tema [17]

Answer:

x=7

Step-by-step explanation:

since the ray bisects we know <CAT and <TAR are equal

so we can set up the equation like this: <CAT + <CAT = <CAR

(5x)+(5x)=(9x+7)

calculate equation and you'll get x=7
