Answer:
2 y^2 (3 y^2 + 7 y - 5)
Step-by-step explanation:
Factor the following:
6 y^4 + 14 y^3 - 10 y^2
Factor 2 y^2 out of 6 y^4 + 14 y^3 - 10 y^2:
Answer: 2 y^2 (3 y^2 + 7 y - 5)
Answer:
Because they have never had to express one quantity in terms of another. The idea of such a relationship is completely new, as is the vocabulary for expressing such relationships.
Step-by-step explanation:
"Function" is a simple concept that says you can relate two quantities, and you can express that relationship in a number of ways. (ordered pairs, table, graph)
The closest experience most students have with functions is purchasing things at a restaurant or store, where the amount paid is a function of the various quantities ordered and the tax. Most students have never added or checked a bill by hand, so the final price is "magic", determined solely by the electronic cash register. The relationship between item prices and final price is completely lost. Hence the one really great opportunity to consider functions is lost.
Students rarely play board games or counting games (Monopoly, jump rope, jacks, hide&seek) that would give familiarity with number relationships. They likely have little or no experience with the business of running a lemonade stand or making and selling items. Without these experiences, they are at a significant disadvantage when it comes to applying math to their world.
Answer:
B
Step-by-step explanation:
-(-a)/b = a/b
Option A is not equal to a/b
But Option B is, after cancelling out the negative sign
To make a prediction as to how much you can climb in 5 hours we can find the line of regression (or line of best fit) for the data given, with time as the explanatory (or independent) variable and height as the response (or dependent) variable. Putting this data into the calculator we get:
Height (ft) = 33.153 + 2.333*Time (min)
Now if we want to predict the distance you are able to climb in 5 hours, we need to convert this to minutes first (as those are the units in the formula) - 5 hours = 300 minutes, thus:
Height (ft) = 33.153 + 2.333*300
= 733.053 ft
733.053 < 1000, therefor it is predicted that it will not be possible to climb a 1000 ft rock formation within 5 hours
Answer:
4
Step-by-step explanation:
To simplify
÷ 
Change division to multiplication and turn the second fraction upside down, that is
× 
Cancel the factor (x + 3) on the numerator/ denominator , leaving
= 4
