Find the distance between the points (7,23) and (3,-3), rounded to the hundredths place​

Mathematics
1 answer:
Molodets [167]3 years ago
5 0

Answer:

26.31

Step-by-step explanation:

Use distance formula

d = \sqrt{(x_{2}-x_{1)^{2} + (y_{2}-y_ ^{1)^2} }  }

substitute in points and solve

d =  \sqrt{(7-3)^2 + (23-(-3))^{2} }

d = \sqrt{4^{2}+26^{2}  }

d = \sqrt{16 + 676}

d = \sqrt{692}

d = 26.30589288

d = 26.31 rounded

Given an int variable n that has already been declared and initialized to a positive value, and another int variable j that has
Inessa05 [86]

Answer:

for(j = n; j > 0; j--)

System.out.print(\"*\");

Step-by-step explanation:

-A for loop is a repetition control structure.

-It allows the efficiency to write a loop that would otherwise be written a couple of times.

-The output is a single line comprising n asterisks,

-The number of asterisks printed will be equivalent to the n-value declared.

F(x) = square root 3x+7 , g(x) = square root 3x-7<br><br> Find (f + g)(x).
Veseljchak [2.6K]
Your basically building a new equation with the two functions given to you.
(sqrt(3x + 7)) + (sqrt(3x - 7)) = 0

Then just open up the brackets and simplify further.
sqrt(3x + 7) + sqrt(3x - 7)= 0

Nothing to special really happened there, just removed the brackets. Now you move one of the radicals to the other side so you can square the whole equation.
sqrt(3x + 7) = - sqrt(3x - 7)

Then go ahead and square both sides to remove the radical.
3x + 7 = 3x - 7

Now if you kept trying to isolate x, you find that both sides will just cancel each other out and you are left with,
7 = -7

Since that statement isn't true your answer will be that there is no solution to this equation.
