Which of the following is the graph of y = 1/x+2 +1
2 answers:
Answer:
The graph of the function has vertical asymptote at x=-2
and horizontal asymptote at y=-1.
Step-by-step explanation:
The graph of the given function:
has a vertical as well as horizontal asymptote at some points.
( An asymptote is a line or curve that approaches a given curve arbitrarily closely
for example 1/x, which has a vertical asymptote at x=0 and a horizontal asymptote at y=0 )
The vertical asymptote of a graph is at x=-2
and horizontal asymptote at y=-1

Answer:
1. 677 inches = 18.056 yards
677 inches = 56.416 feet
677 inches = 677 inches
2. QP = 23.5 cm
3. The perimeter = 53.5 cm
Step-by-step explanation:
1. To convert, 677 inches to yards, we have;
1 inch = 0.0277778 yards
677 inches = 677*0.0277778 = 18.056 yards
To convert, 677 inches to feet, we have;
1 inch = 0.083333 feet
677 inches = 677*0.083333 = 56.416 feet
To convert, 677 inches to inches, we have;
1 inch = 1 inch
677 inches = 677*1 = 677 inches
2. We have that ∠PRQ and ∠PRS are supplementary angles (angles on a straight line
Given that ∠PRS = 90°, ∠PRQ = 180° - 90° = 90°;
∠PRQ + ∠PQR + ∠RPQ = 180°, sum of angles in a triangle
∠PQR = 24° given
∠PRQ = 90°
∴ ∠RPQ = 180° - 90° - 24° = 66°
∴∠SPQ = ∠SPR + ∠RPQ = 36° + 66° = 102°
∠QSP + ∠SPQ + ∠PQS = 180° (sum of angles in a triangle)
∠QSP = 180° -∠SPQ - ∠PQS = 180° -102° - 24 = 54°
By sine rule, we have;
a/(sin(A)) = b/(sin(B))
Therefore, we have;
11.8/(sin(24)) = QP/(sin(54°))
QP = (11.8/(sin(24))) × (sin(54°)) = 23.5 cm
3. From trigonometric ratios, we have;
tan(43°) = BC/CA = BC/(16.2 cm)
BC = 16.2 cm × tan(43°) = 15.1
By Pythagoras theorem, we have;
AB = √(15.1² + 16.2²) = 22.2
The perimeter = 15.1 + 16.2 + 22.2 = 53.5 cm
