Please help, will mark brainliest!
Ugo [173]

Answer:

-1/6 and 1 1/6

I included an image showing the points to select, in red and the point we start at, in blue.

Step-by-step explanation:

We need to get the numbers they tell us (2/3 & 1/2) to have the same denominators as the numbers on the number line before we can start.

1/2 is just the simplified form of 3/6 and 2/3 is just the simplified form of 4/6.

So 1/2 is actually 3/6 on the number line.

Now we need to find the numbers that are 2/3 (or 4/6) unit away from 3/6.

Count 4 units to the right and 4 to the left of 3/6 to get the numbers we are looking for.

These numbers are -1/6 and 1 1/6

I hope this helps!!

Lmk if u have any questions! :)

A chestnut falls out of a tree 45 feet above the ground. Use the vertical motion model, H=-16t^2+vt+s s to find how long it take
valentinak56 [21]

Answer:

1.7 seconds

Step-by-step explanation:

we have

H=-16t^2+vt+s

where

v is the initial velocity (in feet per second)

s represents the initial height (in feet)

In this problem we have

v=0 ---> because the object is dropped

s=45\ ft

substitute

H=-16t^2+45

Remember that

When the chestnut hit the ground the value of H is equal to zero

so

For H=0

-16t^2+45=0

solve for t

16t^2=45\\t^2=2.8125\\t=\pm1.7\ sec

therefore

The solution is t=1.7 sec
