Answer:
4
Step-by-step explanation:
4 is one term, 6c is one term, 14 is one term, and 1 is a term. total=4.
Answer : option d
4.4, 5.8, 7.2, 8.6, 10, …
First we find the common difference between two terms
5.8 - 4.4 = 1.4
7.2 - 5.8 = 1.4
8.6 - 7.2 = 1.4
10 - 8.6 = 1.4
So common difference is 1.4
To find recursive rule, we add the difference with previous term
Recursive rule is 
a1 is the first term so a1= 4.4
d is the difference = 1.4
So recursive rule is
, where a1 = 4.4
Answer:
y-9 = (-3/2)(x+8)
Step-by-step explanation:
point slope form: given (a,b) and slope m the equation is
y-b = m(x-a)
now just plug you given points in
y-9 = (-3/2)(x+8)
Answer:
Not sure if its right
Step-by-step explanation:
A+B=118°
(5x+8)°=118°
13x°=118°
13x/13=118/13
x=9.07
Answer:
15.3 miles.
Step-by-step explanation:
Area of trapezoid is given by = 1/2*( sum of parallel side) height
Given area of trapezoid = 221.85 sq. miles
Length of parallel sides = 19 miles and 10 miles.
Sum of parallel sides = 19 miles + 10 miles = 29 miles.
Plugging the above values in formula for area of trapezoid we have
Area of trapezoid is given by = 1/2*( sum of parallel sides) height
221.85 = 1/2 (29) height
=> 221.85* 2 = 29* height
=> 443.7 = 29* height
=> 443.7/29 = height
=> height = 15.3
Thus, height is 15.3 miles.
