Answer:
y = x^2 +6x +8
Step-by-step explanation:
The vertex is located at (-3, -1) and the graph rises 1 unit vertically for 1 unit away from the vertex. This means the scale factor is 1 and the vertex form equation can be written as ...
y = a(x -h)^2 +k . . . . . vertex form with scale factor a, vertex (h, k)
__
y = (x -(-3))^3 +(-1) . . . fill in the values we know
y = (x +3)^2 -1 . . . . . simplify signs
y = x^2 +6x +9 -1 . . . eliminate parentheses
y = x^2 +6x +8 . . . . . your equation in standard form

Answer:
The width of the bathroom is 10ft.
Step-by-step explanation:
To find the area of a rectangle, we use the formula
<em> </em><em> </em><em> </em><em> </em><em> </em><em> </em><em> </em><em>area</em><em> </em><em>=</em><em> </em><em>width x length</em>
So we know that length is equal to 7 ft, and we also know the total area which is 70 sq.ft.
70 = ? x 7
multiplication and division are inverse operations, so we will divide instead
70 divided by 7 = 10
And we are done!!

<em>Since we are given with the three sides of the triangle and asked to determine the angle, we can use the cosine law.</em>
<em> b² = a² + c² - 2ac(cosB)</em>
<em>Substituting the known values,</em>
<em> (1.8)² = (2.4)² + (1.6)² - 2(2.4)(1.6)(cosB)</em>
<em>The value of B from the equation is 48.6°. </em>
