The square root of
(1-(-7))^2 + (-8-(-2))^2
= the square root of
(64)+(36)
= the square root of 100 or
100^(1/2)
= 10

Therefore, the distance between those two points is 10.

Determine whether the given lengths can be sides of a right triangle. Explain. 10 in., 24 in., 26 in.
notsponge [240]
10 in, 24 in, and 26 in. By the Converse of the Pythagorean Theorem, the lengths must satisfy the equation c² = a² + b². Let 26 = hypotenuse and 10 and 24 the legs of the triangle.
26² = 10² + 24²
676 = 100 + 576
676 = 676.
Yes, they can be lengths of a right triangle.

a rectangle has an area of 30 square meter and a perimeter of 34 meters. what are the dimensions of rectangle?
kow [346]
A=lw
P=2l+2w

30=lw
34=2l+2w

30=lw --> w= \frac{30}{l}

34=2l+2( \frac{30}{l}) \\ 34=2l+ \frac{60}{l}  \\ 34l=2l^2+60 \\ 2l^2-34l+60=0 \\ 2(l-2)(l-15)=0 \\ l=2, 15

30=(2)w
15=w

30=(15)w
2=w

The dimensions can either be 15 x 2 or 2 x 15.

The graph of the function f(x)=10/x+2 is shown below. What is the vertical asymptote of the function? x = –10 x = –2 x = 0 x = 2
White raven [17]
Red line.
Answer: x = -2

f(x)=\dfrac{10}{x+2}\\\\x+2\neq0\to x\neq-2
Therefore, the vertical asymptote of function f(x) is x = -2.
