What type of triangle is formed by joining the points D(7, 3), E(8, 1), and F(4, -1)?

Answers

$D(7,3) \nE(8,1) \nF(4,-1)$

The lengths of the sides of the triangle:
$\overline{DE}=√((8-7)^2+(1-3)^2)=√(1^2+(-2)^2)=√(1+4)=√(5) \n \n\overline{DF}=√((4-7)^2+(-1-3)^2)=√((-3)^2+(-4)^2)=√(9+16)=√(25)=5 \n \n\overline{EF}=√((4-8)^2+(-1-1)^2)=√((-4)^2+(-2)^2)=√(16+4)=√(20)= \n=√(4 * 5)=2√(5)$

No sides are equal to each other, so it's a scalene triangle.

Check if the sides satisfy the Pythagorean theorem:
$(√(5))^2 + (2√(5))^2=5^2 \n5+20=25 \n25=25 \ntrue$
They do, so it's a right triangle.

The triangle is a right scalene triangle.

Have a nice day :)

4.5ft is what circumference of a circle

Answers

Formula for the circumference of a circle is
1). 2 • 3.14 (pi) • r
Or
2) d • 3.14
In this case I'm using #1
Plug in the numbers

2 • 3.14 • 4.5= 28.26

Assume each variable has a different value. Which relations below are functions? a. {(a, b), (a, c), (a, d), (a, e)} b. {(a, b), (b, b), (c, b), (d, b)} c. {(a, b), (c, d), (e, f), (g, h)} d. {(a, a), (b, c), (c, c), (d, e)}A. choice a only

B. choices b and c only

C. choice c only

D. choices b, c, d only

Answers

A function is a relation in which every input value x has at most one output value y.

Consider all options:

a. Relation {(a, b), (a, c), (a, d), (a, e)} is not a function, because input value a has four different output values b, c, d and e.

b. Relation {(a, b), (b, b), (c, b), (d, b)} is a function, because every input value a, b, c and d have at most one output value b.

c. Relation {(a, b), (c, d), (e, f), (g, h)} is a function, because every input value a, c, e and g have at most one output value b, d, f and g, respectively.

d. Relation {(a, a), (b, c), (c, c), (d, e)} is a function, because every input value a, b, c and d have at most one output value a, c, c and e, respectively.

Answer: correct choice is D

i think its D but im not 100% sure let me know if its right

Why are cubes and spheres called solid figures?

Answers

They are called solid figures, because they are both 3 dimensional. Squares and circles are only 2 dimensional so, that's why.
