Answer:
Area: T = 18
a. The triangle area using Heron's formula: T= sqrt(s(s−a)(s−b)(s−c)
)
b. 2
c. h = 5.69
d. T = 18
Step-by-step explanation:
a. T= sqrt(s(s−a)(s−b)(s−c)
)
T=sqrt(
11.16(11.16−10)(11.16−6)(11.16−6.32)
)
T= sqrt(324
)
T =18
b. We compute the base from coordinates using the Pythagorean theorem
c= sqrt( ((−2−4)^2)+ ((1−3) ^2)
)
c= sqrt(40) = 2sqrt(10)
c. Calculate the heights of the triangle from its area
Given:
The two points are C(3,-5) and D(7,9).
To find:
The midpoint M of the given points.
Solution:
We know that,
Using the midpoint formula, the midpoint of C(3,-5) and D(7,9) is
Therefore, the midpoint M of two points C(3,-5) and D(7,9) is (5,2).
Y = -2.5x + 45
That's your equation. Your y-intercept would be 45 because that's what she started with. It would be a negative slope as well.
The answer to this question is: 300
