Height of window 0.6 feet less than 2.5 times it width height of window 4.9 feet
AURORKA [14]
Suggest you use some punctuation here:  "The h<span>eight of window is 0.6 feet less than 2.5 times it width.  The height of window  is 4.9 feet.  Find the width of the window."

height of window = 4.9 feet = 2.5(width) - 0.6 feet.

simplify this equation by adding 0.6 feet to both sides of the equation:

4.9 feet + 0.6 feet = 2.5 (width); find width:

5.5 feet = 2.5 (width)

Dividing both sides of this equation by 2.5 will result in an equation for the width of the window, in feet.</span>

Order from least to greatest 0.5, 1/5, 0.35, 12/25, 4/5
sdas [7]
First change them all into either fractions or decimals. Decimals are probably easier though. 1/5 = 0.2; 12/25 = 0.48; 4/5 = 0.8 
Order: 0.2, 0.35, 0.48, 0.5, 0.8
Then you change the decimals that you converted back into the fraction form
Answer: 1/5, 0.35, 12/25, 0.5, 4/5

Drag each real-world situation to the correct column to show whether it can be modeled by combining additive inverses to get 0.
Flauer [41]

Answer:

. An investment account earns 2.8% simple interest.

   Since investment amount increases every year linearly, therefore, the modeled situation represents a LINEAR FUNCTION.

B). The price of a stock varies by 2.8% each week.

   Since price of the stock may increase or decrease every week, therefore, this situation can't be modeled by any function.

Therefore, the answer is NEITHER.

C). An investment account earns 2.8% compound interest, compounded monthly.

Formula to get the value of the final amount in the account is,

Final value = Initial value ×

Here 't' = Duration of investment

It's an EXPONENTIAL FUNCTION.

Answer:

3a^{4} - 48

Step-by-step explanation:

Given

(a + 2)(3a² + 12)(a - 2)

= (a + 2)(a - 2)(3a² + 12) ← expand the first pair of parenthesis using FOIL

=(a² - 4)(3a² + 12) ← expand using FOIL

= 3a^{4} + 12a² - 12a² - 48 ← collect like terms

= 3a^{4} - 48
