Find the distance between the points (2,3) (-3,-6)

Valentin [98]

Answer:

10.3

Step-by-step explanation:

As we move from (-3,-6) to (2,3), x increases by 5 (this is the horizontal distance between (2,3) and (-3,-6) ) and y decreases by 9 (vertical distance).

We apply the Pythagorean Theorem here:

d^2 = x^2 + y^2, or

d^2 = (5)^2 + (-9)^2 = 25 + 81 = 106

Thus, the distance between (2,3) and (-3,-6) is d = sqrt(106), or approx.

Point Q is located at (-4, 6). Point R is located at (8, 6).

Bess [88]

Step-by-step explanation:

Hi there!

Given;

Point Q is located at (-4, 6). Point R is located at (8, 6).

Note: Use distance formula.

Now;

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

Keep all values;

$(d) = \sqrt{ {(8 + 4)}^{2} + ( {6 - 6)}^{2} }$

Simplify;

$(d) = \sqrt{( {12)}^{2} }$

Therefore, the distance is 12 units.

Hope it helps!

SIMPLIFY 7/10+1/4-1/5=

Strike441 [17]

Answer:

3/4

Step-by-step explanation:

Q = $\frac{7}{10} +\frac{1}{4} -\frac{1}{5}$

{the smallest common multiple of 10, 4 and 5 is 5×2×2 = 20 (denominator)}

Q = $\frac{7×2}{10×2} +\frac{1×5}{4×5} -\frac{1×4}{5×4}$

= $\frac{14}{20} +\frac{5}{20} -\frac{4}{20}$

= $\frac{14+5-4}{20}$

= $\frac{15}{20}$

= $\frac{3×5}{4×5}$

= $\frac{3}{4}$
