Plug it into a graphing calculator and see where the function crosses the x-axis. Since it’s a quadratic it will cross it two times but one of the answers is negative—obviously it wouldn’t take negative second to hit the ground. It should take 9 seconds for the object to hit the ground.

HELP NEEDED ASAP WILL GIVE 5 STAR RATING AND BRAINLIEST!
stealth61 [152]

Answer:

The answer to your question is: ∠K   = 138°

Step-by-step explanation:

m∠N = 42°

m∠K = ?

The sum of all the internal angles in a quadrangle equals 360°

then

        ∠N + ∠L + ∠M + ∠K = 360°

        ∠N = ∠ L   and ∠M = ∠K

So, 2 ∠N + 2 ∠K = 360

Substitution

       2 (42) + 2 ∠K = 360

       84  + 2 ∠K = 360

       2 ∠K = 360 - 84

       2 ∠K = 276

      ∠K  = 276 / 2

     ∠K   = 138°

What is 6.213 as a mixed number
Ira Lisetskai [31]
6.213 as a mixed number would be 6 and 213/1000.

all you do to convert it to a mixed number is look at how many numbers are after the decimal.

since theres 3 numbers, that means it would be in the thousands place

How are fractions and decimals related?
Savatey [412]
Fractions and decimals are related in a very close way. Ways such as they are both representing a whole number. 

for example 

1/2 , 0.5 , 50% 

all three numbers have the same value but are expressed in a different format. all three represent the same whole number. 

another example would be

1/4 , 0.25 , 25% 

hopefully this helped. and or makes sense. 

LET ME KNOW :p

Find the length and width of a rectangle that has the given perimeter and a maximum area. perimeter: 244 meters
MissTica
We know that

[perimeter of rectangle]=2*(<span>length+width)
</span>
Let
x-----------> length
y-----------> width
so
P=2*(x+y)-----------> 244=2*(x+y)-----> x+y=122-------> y=122-x

Area=x*y-------> x*(122-x)----> 122x-x²

find the derivative function and equals to zero

122-2x=0-----> 122=2x----------> x=61 m
y=122-x------> y=122-61---------> y=61 m

<span>the maximum area is given by a square
</span>
the answer is
is a square of side 61 m
