Round 1.0649 to the nearest thousandth
ira [324]
1.0649 to the nearest thousandths is 1.065

You could get this by finding where the thousandths place is, which is the third number.
Now, look at the number to the right. 
If it's 5 or higher, round up. 
If it's 4 or lower, round down.

Since it is 9, we round up.
The 4 turns into a 5.

So, 1.065

Hope I helped!

On a coordinate plane, a point is at (negative 4, negative 4) and (negative 4, negative 10).
Valentin [98]

Answer:

Option C.

Step-by-step explanation:

Hey there!

The points are; (-4,-4) and (-4,-10).

<u>Use </u><u>distance</u><u> formula</u><u>.</u>

d =  \sqrt{ {(x2 - x1)}^{2} +  {(y2 - y1)}^{2}  }

~ Put all values.

d =  \sqrt{ {( - 4 + 4)}^{2}  + (  { - 10  + 4)}^{2} }

~ Simplify it.

d =  \sqrt{ {0}^{2} + ( { - 6)}^{2}  }

d =  \sqrt{36}

Therefore, distance between the points is 6 units.

An airplane climbs 100 feet during the first second after takeoff. In each succeeding second it climbs 100 feet more than it cli
tigry1 [53]

Answer:

15 seconds.

Step-by-step explanation:

∵ The distance covered by plane in first second = 100 ft,

Also, in each succeeding second it climbs 100 feet more than it climbed during the previous second,

So, distance covered in second second = 200,

In third second = 300,

In fourth second = 400,

............, so on....

Thus, the total distance covered by plane in n seconds = 100 + 200 + 300 +400......... upto n seconds

=\frac{n}{2}(2\times 100 + (n-1)100)  ( Sum of AP )

=\frac{n}{2}(200+100n-100)

=\frac{n}{2}(100+100n)

=50n+50n^2

Suppose the distance covered in n seconds is 12,000 feet,

\implies 50n+50n^2=12000

n+n^2=240

n^2+n-240=0

n^2+16n-15n-240=0

n(n+16)-15(n+16)=0

(n-15)(n+16)=0

\implies n=15\text{ or }n=-16

∵ n can not be negative,

Hence, after 15 seconds the plane will reach an altitude of 12,000 feet above its takeoff height.
