Answer:
D f(n) = 7n-12
Step-by-step explanation:
The first term is -5
The second term is -5+7 =2
The common difference is 7
an = a1 +d(n-1) where d is the common difference
= -5 +7(n-1)
Distribute the 7
= -5 +7n -7
7n -12
Answer:
Jasmine ran last week 37.2 miles
Step-by-step explanation:
Let
x ----> number of miles Rob ran last week
y ----> number of miles Jasmine ran last week
we know that
x=y-27.2 ----> equation A
x=10 ----> equation B
Substitute equation B in equation A and solve for y
10=y-27.2
y=10+27.2
y=37.2 miles

Answer:
972π in³
Step-by-step explanation:
The volume (V) of a sphere is calculated as
V = 
πr³ ← r is the radius
Here r = 9, thus
V = π × 9³ = π × 729 ( divide 3 and 729 by 3 )
= 4π × 243
= 972π in³
