3 0

Answer:

(- 3, 0 ), (- 1, 0 )

Step-by-step explanation:

Given

x² + 4x + 3 = 0

Consider the factors of the constant term (+ 3) which sum to give the coefficient of the x- term (+ 4)

The factors are + 3 and + 1, since

3 × 1 = 3 and 3 + 1 = 4, thus

(x + 3)(x + 1) = 0

Equate each factor to zero and solve for x

x + 3 = 0 ⇒ x = - 3

x + 1 = 0 ⇒ x = - 1

Coordinates of roots are (- 3, 0 ) and (- 1, 0 )

A geometric sequence is shown below.
mestny [16]

Answer:

An explicit representation for the nth term of the sequence:

f_n=-\frac{1}{2}\cdot \:4^{n-1}

It means, option (B) should be true.

Step-by-step explanation:

Given the geometric sequence

-\frac{1}{2},\:-2,\:-8,\:-32,...

A geometric sequence has a constant ratio, denoted by 'r', and is defined by

f_n=f_1\cdot r^{n-1}

Determining the common ratios of all the adjacent terms

\frac{-2}{-\frac{1}{2}}=4,\:\quad \frac{-8}{-2}=4,\:\quad \frac{-32}{-8}=4

As the ratio is the same, so

r = 4

Given that f₁ = -1/2

substituting r = 4, and f₁ = -1/2 in the nth term

f_n=f_1\cdot r^{n-1}

f_n=-\frac{1}{2}\cdot \:4^{n-1}

Thus, an explicit representation for the nth term of the sequence:

f_n=-\frac{1}{2}\cdot \:4^{n-1}

It means, option (B) should be true.

The school printer has purchased a new color printer that can produce 75 pages in 5 minutes. If the printer were to print only 1
lawyer [7]

Answer:

15 pages

Step-by-step explanation:

This is a fairly simple problem meaning it has very few steps. If it makes 75 pages in 5 minutes you need to find out what the PPM or Page Per Minute is.

To find that you simply divide 75 by 5 and get 15 and in one minute the printer prints 15 pages.

Which angles are complementary<br> to &lt;2. Select all that apply.
KiRa [710]

Answer:

∠1 only

Step-by-step explanation:

Complementary angles:

  • sum to 90°
  • form a right angle

The only angle (that's an answer choice) that helps form a right angle with angle 2 is angle 1, thus making it the correct answer.

Have a lovely rest of your day/night, and good luck with your assignments! ♡
