The image shows a geometric representation of the function f(x) = x2 – 2x – 6 written in standard form. An algebra tile configur
Over [174]

Answer:

f(x)=(x-1)^2-7

Step-by-step explanation:

Standard form:

f(x)=x^2-2x-6

Vertex form:

y=(x-h)^2+k

(h, k) is the vertex

x is the coordinate of the vertex

To find x use the formula:

x=\frac{-h}{2a}

f(x)=x^2-2x-6

a=1

b=-2

c=-6

Substitute:

x=\frac{-(-2)}{2(1)}=1

Substitute x in equation:

f(x)=1^2-2(1)-6\\f(x)=1-2-6\\f(x)=-7

h=1

k=-7

Substitute h, and k into the vertex formula:

f(x)=(x-1)^2-7

Trigonometry
Alchen [17]

The area of the triangle PQR is 17.6 square units.

Explanation:

Given that the sides of the triangle are PQ = 12 and PR = 3 and m\angle P = 78^{\circ}

We need to determine the area of the triangle PQR

<u>Area of the triangle:</u>

The area of the triangle can be determined using the formula,

\text {Area}=\frac{1}{2} qr \sin P

Substituting the values, we get,

\text {Area}=\frac{1}{2}(12)(3) \sin 78

Simplifying, we have,

\text {Area}=\frac{1}{2}(36)(0.98)

Multiplying the terms, we have,

\text {Area}=\frac{35.28}{2}

Dividing, we get,

\text {Area}=17.64

Rounding off to the nearest tenth, we have,

Area=17.6

Thus, the area of the triangle PQR is 17.6 square units.
