V125BC [204]3 years ago
7 0

Answer:

B and E

Step-by-step explanation:

A. 8x = 2

8(4) = 2

32 = 2

B. 19 + x = 23

19 + 4 = 23

23 = 23

C. 40/x = 5

40/4 = 5

10 = 5

D. -3x = 12

-3(4) = 12

-12 = 12

E. x - x - x - x = -8

4 - 4 - 4 - 4 = -8

0 - 4 - 4 = -8

-4 - 4 = -8

-4 + (-4) = -8

-8 = -8

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

If f(x) = |x| + 9 and g(x) = –6, which describes the value of (f + g)(x)?
Kryger [21]
(f+g) (x)= f(x) + g(f)

= IxI + 9 + (-6) 

= IxI + 9 - 6

= IxI + 3

(f + g)(x) = IxI + 3

tresset_1 [31]

Answer:

Number of year in which population will be 180,000 = 6 year (Approx.)

Step-by-step explanation:

Given:

Population in 2007 = 168,979

Rate of increase in population = 1% = 0.01

Future population = 180,000

Find:

Number of year in which population will be 180,000

Computation:

A = P[1+r]ⁿ

Future population = Population in 2007[1+Rate of increase in population]ⁿ

180,000 = 168,979[1+0.01]ⁿ

180,000 = 168,979[1.01]ⁿ

1.06522 = [1.01]ⁿ

n = 6 (Approx.)

Number of year in which population will be 180,000 = 6 year (Approx.)
