Find the distance between the points (3 4) and (4 3)

Usimov [2.4K]

Answer:

$\sqrt{2}$ or 1.414213

Step-by-step explanation:

Use the distance formula to determine the distance between the two points.

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

d = distance

$(x_{1}, y_{1})$ = coordinates of the first point

$(x_{2}, y_{2})$ = coordinates of the second point

Evaluate the expression if b=44 14 b - 513 a.88 b.103 c.86 d.100 e.94 f.92

Nataliya [291]

Evaluating an expression consists of just replacing the letter by its value and do the calculus.
We have the expression 14b - 513. And by hypothesis, b = 44.
So just replace b by 44.

14b - 513 = 14*44 - 513 = 616 - 513 = 103.

So 14b - 513 = 103 (answer b) when b = 44.

Hope this helps! :)

5/6 , 7/18 , 11/24 , 19/36 in descending order

motikmotik

Answer: 5/6, 19/36, 11/24, 7/18

Step-by-step explanation:

Descending order is going from largest to smallest. We can do this by comparing the fractions. We make all the fractions have the same denominator. Then we will see which has the larger numerator.

$\frac{5}{6} , \frac{7}{18} , \frac{11}{24} , \frac{19}{36}$

A common denominator we can use is 72, since it is a common multiple.

$\frac{60}{72} ,\frac{28}{72}, \frac{33}{72}, \frac{38}{72}$

Now that all the numbers have the same denominator, we compare to see which number is largest to smallest.

$\frac{60}{72} ,\frac{38}{72} ,\frac{33}{72} ,\frac{28}{72}$

With our descending order, let's put it back into the original fractions.

$\frac{5}{6} ,\frac{19}{36} ,\frac{11}{24} ,\frac{7}{18}$
