Y=.012x-2 since this way the equation doesn’t go down and so it doesn’t start in the negatives

Solve and in standard form please. you must add. this is from khan academy

We are asked to sum the two trinomials $(-4f^3-5f+16)+(4f^2-f+9)$ . We can start by using the distributive property to remove the parenthesis, giving us $-4f^3-5f+16+4f^2-f+9$ . Next, when we combine like terms, we get $\boxed{-4f^3+4f^2-6f+25}$ . Hope this helped!

A pile of earth removed from an excavation is a cone measuring 6ft high and 30ft across its base. How many trips will it take to

nignag [31]

Answer: 14

Step-by-step explanation:

Given

Excavation cone measures

height $h=6\ ft$

Diameter $d=30\ ft$

Truck can dump $125\ ft^3$ at a time

The volume of a cone is

$V=\dfrac{1}{3}\pi r^2h$

Putting values

$\Rightarrow V=\dfrac{1}{3}\times \pi\times 15^2\times 6\\\Rightarrow V=1413.9\approx 1414\ ft^3$

No of trips(N) required to accumulate this much volume is given by

$\Rightarrow N=\dfrac{1414}{125}=13.3\approx 14$

Therefore, 14 trips are necessary to accumulate a cone of volume $1414\ ft^3$
