The distance between (-2, 3) and (-5, 1) is √13.

or, the distance between (-2, 3) and (1, 1) is √13.

We know that the length of the line segment connecting any two points represents the distance between them. There is just one line that connects the two points. Therefore, by measuring the length of the line segment that connects the two points, the distance between them can be determined. If (a, b) and (c, d) be two points, then the distance between them is \sqrt[]{(b - a)^{2} +(d- c)^{2} }.

Here, one point is (-2, 3).

Let the other point be (x, 1).

Given that the distance is √13.

Now, \sqrt[]{(x - (-2))^{2} +(1 - 3)^{2} } = \sqrt{13}  

i.e. \sqrt[]{(x + 2)^{2} +( - 2)^{2} } =\sqrt{13}

i.e. \sqrt[]{x^{2}+4x +4 +4 }=\sqrt{13}

i.e. x^{2}+4x +8 =13

i.e. x^{2}+4x + 8- 13=0

i.e.x^{2}+4x -5=0

i.e. x^{2} +5x - x -5=0

i.e. x(x+5)-1(x+5)=0

i.e. (x+5)(x-1)=0

i.e. x=-5,1

So, the point is either (-5, 1) or (1, 1).

Therefore, the required point is either (-5, 1) or (1, 1).

i.e. the distance between (-2, 3) and (-5, 1) is √13.

or, the distance between (-2, 3) and (1, 1) is √13.

Which trigonometric function has the same value as sin 75?
Sonbull [250]
The answer would be tan (44).

For sin (75)
The answer will be computed this way:
sin 75º = sin (30)º + 45º= sin 30 cos 45+cos 30 sin 45= 1/2*√2/2+√3/2*√2/2=√2/4+√6/4=(√2+√6)/4Check with calculator:sin 75º ≈ 0.9659

For tan (44): checking with the calculator the answer is also: ≈ 0.9659

what is 2/a = a/50. These are factions if you already didn't know. I need to know what the answer is. it is a proportion.
Natalija [7]
2/a= a/50

Cross multiply:
a* a= 2*50
⇒ a^2= 100
⇒ a= √100 or a= -√100
⇒ a= 10 or a= -10

Final answer: a= 10 or a= -10~

For f(x) = x^2, find f(4 - sqrt(2))
ryzh [129]
\bf f(x)=x^2\qquad f(4-\sqrt{2})\implies x=4-\sqrt{2}&#10;\\\\\\&#10;f(4-\sqrt{2})=\left( 4-\sqrt{2} \right)^2\implies f(4-\sqrt{2})=\left( 4-\sqrt{2} \right)\left( 4-\sqrt{2} \right)

do a FOIL on it to get the product, or just use the binomial theorem to expand the binomial and simplify
