Answer:
PR = 180 cm
Step-by-step explanation:
Given PQ : QR = 7 : 3 = 7x : 3x ( x is a multiplier )
PQ - QR = 72, substitute values
7x - 3x = 72
4x = 72 ( divide both sides by 4 )
x = 18
Thus
PR = PQ + QR = 7x + 3x = 10x = 10 × 18 = 180 cm
Answer:
(a,c) ∪ (f, g)
Step-by-step explanation:
The function is:
- concave down in the intervals: (a,c) and (f, g)
- concave up in the intervals: (c, f) and (h, g)
Draw the slope of the tangent lines of several points on the curve,
- if the slope increases, the segment is concave up
- if the slope decreases, the segment is concave down.
Answer:
Area = 77 yd²
Step-by-step explanation:
Width = w
Length = w+4
Perimeter =36
Perimeter = L + L + w + w
36 = w+4+w+4+w+w
4w+8 =36
Subtract 8 from both sides
4w = 36 - 8
4w =28
Divide both sides by 4
W= 28/4
W= 7yd
Therefore length = w+4 = 7+4 = 11 yd
Area = length x width
Area = 11× 7
Area = 77 yd²
