Answer:
aₙ= 4n+11
Step-by-step explanation:
the sequence 15, 19, 23, 27
is AP with the first term 15 and
the common difference 19-15=23-19=27-23= 4
aₙ= a₁+(n-1)d
aₙ= 15+(n-1)*4= 15+4n- 4= 4n+11
aₙ= 4n+11
Answer:
y = 0.5x + 50.95
Step-by-step explanation:
Given y is total cost while x is total miles
Slope: m = (y2-y1)/(x2-x1)
m = (75.95-65.95)/(50-30) = 10/20 = 0.5
y = mx + b
y = 0.5x + b
75.95 = 0.5(50) + b
b = 50.95
Slope intercept form: y = 0.5x + 50.95
Answer: B
Step-by-step explanation:
The answer is 1/4 because she used 3/4 of the paint on 3 out of 4 walls.
125 cubic meters
V=lwh
125= 5 • 5 • 5
