Right isosceles ΔA B C has hypotenuse length h . DE is a midsegment with length 4 x that is not parallel to the hypotenuse. What
Kruka [31]

The perimeter of right isosceles ΔABC with midsegment DE is 16 + 8√2.

If right isosceles ΔABC has hypotenuse length h, then the two other sides are congruent.

side a = side b

Using Pythagorean theorem, c^2 = a^2 + b^2

h^2 = a^2 + b^2      a = b

h^2 = 2a^2

a = h/√2

If DE is a midsegment not parallel to the hypotenuse, then it is a segment that connects the midpoints of one side of a triangle and the hypotenuse. See photo for reference.

ΔABC and ΔADE are similar triangles.

a : b : h = a/2 : 4 : h/2

If a/2 = a/2, then b/2 = 4.

b/2 = 4

b = 8

If a = b, then a = 8.

If a = h/√2, then

8 = h/√2

h = 8√2

Solving for the perimeter,

P = a + b + h

P = 8 + 8 + 8√2

P = 16 + 8√2

P = 27.3137085

What is the equation in slope-intercept form of the line that passes through the points (0, −4) and (2, 0)?
Nastasia [14]

Answer:

y = 2x -4

Step-by-step explanation:

Slope intercept form is  y = mx + b where <em>m </em>is the slope and <em>b </em>is the y-intercept.

Slope is \frac{rise}{run} or \frac{y_2 - y_1}{x_2-x_1} in this case = \frac{0 - (-4)}{2 - 0} = \frac{4}{2} = 2

Substitute one of the coordinates for x and y. I am going to use (0, -4) so:

-4 = 2(0) + b\\-4 = 0 + b\\-4 = b

since m = 2 and b = -4, we can conclude that the equation would be

y = 2x -4

The diameter of a circle is 20 feet. Using the formula A = r2, what is the area of the circle? Use 3.14 for pi.
sergey [27]
Area = PI * radius ^ 2
radius = 10 feet
Area = PI * 100
Area = 3.14 * 100
Area = 314 square feet
