Step-by-step explanation:
the area of a triangle is always
baseline × height / 2
where baseline and height are perpendicular (with a 90° angle) to each other.
it does not matter, if the height is inside or outside of the triangle.
so, in our case the area is
4×5/2 = 2×5 = 10 units²
Answer:
The rock splashes down when h(t) = 0. Set h(t) = 0 and solve for t using quadratic formula.
0 = − 4.9t^2 + 178t + 325
t = 38.07, -1.74
(Throw away the negative answer, since time can't be negative.)
t = 38.07 sec

Isolate the variable(x) by dividing each side by factors (50) that do not contain the variable.
Answer:
2
Step-by-step explanation:
-13 x 2 = -26
-4 x 2 = -8
14 x 2 = 28
-26 + -8 + 28 +-9 = -15
