Answer:
(5/2, 29/2), and this represents a maximum
Step-by-step explanation:
g(x) = -2x^2 + 10x + 2 is a quadratic function with coefficients {-2, 10, 2}.
The formula for the axis of symmetry (which passes through the vertex) is
x = -b/ [2a]. Here, a = -2; b = 10. Therefore, the axis of symmetry is
x = -10/ [2(-2)] = -10/(-4) = 5/2
Evaluate the function g(x) = -2x^2 + 10x + 2 at x = 5/2 to determine the y-coordinate of the vertex:
g(5/2) = -2(5/2)^2 + 10(5/2) + 2, or
g(5/2) = -2(25/4) + 25 + 2, or
g(5/2) = -25/2 + 27, or
g(5/2) = 14.5
The vertex is thus (5/2, 29/2), and this represents a maximum, because the coefficient of the x^2 term is negative (the curve opens downward).

Answer:
The answer is below
Step-by-step explanation:
A triangle is a polygon with three sides and three angles. Types of triangles are scalene, right angled, isosceles, equilateral.
A right angled triangle is a triangle with one angle equals to 90°.
Statement Reason
∠PQR = ∠RST Given. ∠PQR = ∠RST = 90° (definition for right
angle triangle.
PQ = ST Given
PR ≅ RT Since R is the midpoint of PT, hence PR = RT
ΔPQR ≅ ΔTSR Side-angle-side triangle congruence theorem.
the Side-angle-side triangle congruence theorem
states that if two sides and an included angle of
one triangle is equal to two sides and an included
angle of another triangle, then the two triangles
are congruent. PQ=ST, PR = RT and ∠PQR = ∠TSR
