Answer:

B

Step-by-step explanation:

Well since it is arthimetic sequence we know the formula

We know d is difference between second term and first so it will be -5- (-12)= -5+12= 7

a_{n}= a _{1}+ d (n-1) \\a_{n}= -12+7(n-1)\\a_{n} = -12+7n-7\\a_{n}= 7n-19

the domain of this is 1,2,3,4.......

range is -12,-5,2,9.......

Therefore answer is B.

Please answer! If you don’t mind, can you explain
stich3 [128]

Answer:

see explanation

Step-by-step explanation:

Using the given formula for area : A = \frac{1}{2} bh

(a) given b = 8 and h = 5, then

A = \frac{1}{2} × 8 × 5 = \frac{1}{2} × 40 = 20 units²

(b) given A = 18 and b = 4, then

18 = \frac{1}{2} × 4 × h = 2h ( divide both sides by 2 )

h = 9 units

(c) given A = 14 and h = 7, then

14 = \frac{1}{2} × 7 × b = 3.5b ( divide both sides by 3.5 )

b = 4 units

lesya [120]

Answer:

F

Step-by-step explanation:

First, converting R percent to r a decimal

r = R/100 = 6%/100 = 0.06 per year,

then, solving our equation

I = 5500 × 0.06 × 2.5 = 825

I = $ 825.00

The simple interest accumulated

on a principal of $ 5,500.00

at a rate of 6% per year

for 2.5 years is $ 825.00.
