20 points! I would really like some help! :) (Question attached below)
snow_lady [41]

Answer:

See below.

Step-by-step explanation:

(a)

To multiply two polynomials, multiply every term of the first polynomial by every term of the second polynomial. Then combine like terms.

(\dfrac{1}{2}x - \dfrac{1}{4})(5x^2 - 2x + 6) =

= \dfrac{1}{2}x \times 5x^2 - \dfrac{1}{2}x \times 2x + \dfrac{1}{2}x \times 6 - \dfrac{1}{4} \times 5x^2 + \dfrac{1}{4} \times 2x - \dfrac{1}{4} \times 6

= \dfrac{5}{2}x^3 - x^2 + 3x - \dfrac{5}{4}x^2 + \dfrac{1}{2}x - \dfrac{3}{2}

= \dfrac{5}{2}x^3 - \dfrac{9}{4}x^2 + \dfrac{7}{2}x - \dfrac{3}{2}

(b)

No. Since the binomials are different, the product of two different binomials and the same trinomial will give different results.

Karen Gaines invested $12,000 in a money market account with an interest rate of 2.25% compounded semiannually. Six years later,
deff fn [24]

Answer:

$13,724

Step-by-step explanation:

From the above question, we are given the following values:

Principal = P = $12,000

Interest = r = 2.25% = 0.0225

Compounded semi annually = n = 2

Time (t) = 6 years

From the question, we understand that we are to find the total (full) Amount Karen withdrew.

The formula to use to calculate the Total Amount of money given that this is a compound interest question is:

Total(full) Amount = P( 1 + r/n) ^n/t

= $12,000( 1 + 0.0225/2) ^2×6

= $12,000(1.01125)^12

= $13724.093289

Approximately to the nearest cent

≈ $13,724

Therefore, Karen withdrew $13,724 from the account.

Question 7: please help. I will give brainliest to correct answer.
liq [111]

Answer:

0.03

Step-by-step explanation:w

standard deviation = ( p(1-p) / n)1/2

p= sample proportion= 55%

n= sample size = 900

standard deviation = ( [55/100] [ 1- 55/100]) / 900)1/2

= (0.55*0.45 / 900)1/2

= 0.0165

margin of error = critical value*standard deviation

[ from graph critical value = 2]

margin of error = 2*0.0165=0.033

A piece of pipe is 303/4 inches long. If five pieces, each 41/3 inches long, are cut from the pipe, how many inches of pipe rema
galina1969 [7]
So, what is the total lenght of the pieces that wer cut off?

we multiply the lenght by the number:

4 \frac{1}{3}*5=20+\frac{5}{3}=21\frac{2}{3}

and we subtract this from the original pipe, that is

30\frac{3}{4}-21\frac{2}{3}

we need to bring the two fractions to the same denominator (by multiplying the fraction art in the first by 3 and 4 the second):

30\frac{9}{12}-21\frac{8}{12}=9 \frac{1}{12}

so the correct answer is D!
