$20x^5-8x^4$ polynomial of the 5th degree, with two terms.

Distribute 4x^2(–2x^2 + 5x^3) to get –8x^2 + 20x^5. Reorder in standard form 20x^5-8x^4. 5 is the highest exponent so it is the 5th degree, there are two terms because terms are separated by a plus or minus.

ΔABC is a right triangle
By the Pythagorean theorem:
AC = √(BC² - AB²) =√(5²-3²) = √(25-9) = √16 = 4

ΔBED is a right triangle
DE = 4
BE = AB + AE = 3 + 4 = 7
By the Pythagorean theorem:
BD = √(BE² + DE²) =√(7²+4²) = √(49+16) = √65

Answer: BD = √65

Last year, Felipe invested his money in two purchases. He purchased a certificate of deposit for $12,000 that paid 6% interest p

Alexus [3.1K]

Same as the other one

part A)

CD 12,000 at 6%, how much is that? (6/100) * 12000

CB 4000 at 5%, how much is that? (5/100) * 4000

part B)

total investment was 12000 + 4000 = 16000

the earned interest above are 720 and 200 respectively

total yield was, 720 + 200 = 920

if 16000 is the 100%, how much is 920 in percentage?

$\bf \begin{array}{ccllll}
amount&\%\\
\text{\textemdash\textemdash\textemdash}&\text{\textemdash\textemdash\textemdash}\\
16000&100\\
920&x
\end{array}\implies \cfrac{16000}{920}=\cfrac{100}{x}$

solve for "x"

Deanna borrowed $650 at 8% 0 simple interest. How much - 52 interest did she pay for 1 year?

Ronch [10]

Answer:

i = ($650)(0.08)(1) = $52

Step-by-step explanation:

The formula for simple interest is i = prt. Here p = $650, r = 0.08 and t = 1 (year). Then the simple interest Deanna paid for this one year loan was

i = ($650)(0.08)(1) = $52
