If T(n)=3n-1,what is the 3rd term?

exis [7]

Plug in 3 for n, since you're looking for the third term.
T(1) = 3(1) - 1 = 2
T(2) = 3(2) - 1 = 5
T(3) = 3(3) - 1 = 8
It would be 8.

What is the value of n? n–2= 10n+ 4/2 Enter your answer in the box.

pentagon [3]

Answer:

-4 / 9

Step-by-step explanation:

n - 2 = 10n + 4/2

n - 10n = 4/2 + 2

-9n = 4/2 + 4/2 ( taking LCM of 4/2 and 2)

-9n = 8/2

-9n = 4

n = 4 / -9

therefore n = -4 /9 ( since the minus sign doesn't make a difference whether placed at numerator or denominator) .

The value of Bulls Eye stock has decreased 8% each year for the past several years. If in 2010 the stock was worth

Ivenika [448]

Answer:

$ 32.95

Step-by-step explanation:

Cost of Stock at 2010= $ 50

Declining rate each year= 8%

We have to find cost of stock at 2015

Cost of stock after 5 years= $ 50 $(1-\frac{8}{100} )^{5}$

Value of stock after 5 years= $ 50 $(\frac{100-8}{100} )^{5}$

Value of stock after 5 years= $ 50 $(\frac{92}{100} )^{5}$

Value of stock after 5 years= $ 32.95

Hence, the correct answer is $ 32.95
