Answer: C. p = p

<u>Step-by-step explanation:</u>

A tautology is a statement that is always true.

A. p = q

This is not always true. Counterexample: p = 1 & q = 2

B. p = q

This is the same as A (above)

C. p = p

This is ALWAYS true!

D. q = p

This is the same as A but in reverse order.

An Impressionist painting increases in value
jok3333 [9.3K]

Answer:

A = $8406.6

Step-by-step explanation:

Given:

Average rate r=9\%

Initial cost of painting a = \$1500

Time t = 20\ years

We need to find the final amount of painting at the end of a 20-year.

Solution:

Using Exponential Growth rate formula as:

A = a(1+r)^t  ----------(1)

Where:

A = Final amount

a = Initial amount.

r = Rate as a decimal.

t = Time.

Now, we substitute all given values in equation 1.

A = 1500(1+0.09)^{20}

A = 1500(1.09)^{20}

Substitute 1.09^{20} = 5.60 in above equation.

A = 1500\times 5.60

A = $8406.62

Therefore, value of the  painting at the end of  a 20-year A = $8406.6

wanting some extra help with factoring while knowing what method it would be like gcf or grouping etc
Ksju [112]

d) You have a <u>difference of squares</u>:

49y² - 9 = (7y)² - 3²

Recall the identity,

a² - b² = (a - b) (a + b)

So,

49y² - 9 = (7y - 3) (7y + 3)

e) Pull out the common factor 3 from each term:

3x² - 3x - 90 = 3 (x² - x - 30)

Now use the <u>sum-product method</u>. Notice that we can write 30 = 5 • 6, and 5 - 6 = 1, so

3x² - 3x - 90 = 3 (x + 5) (x - 6)

f) Same as in (e), use the <u>sum-product method</u>. Notice that 42 = 7 • 6, and -7 - 6 = -13, so

x² - 13x + 42 = (x - 7) (x - 6)
