5 0

Answer: 1.79

Step-by-step explanation: x2−6x−14=0

For this equation: a=1, b=-6, c=-14

1x2+−6x+−14=0

Step 1: Use quadratic formula with a=1, b=-6, c=-14.

x=

−b±√b2−4ac

2a

x=

−(−6)±√(−6)2−4(1)(−14)

2(1)

x=

6±√92

2

x=3+√23 or x=3−√23

Answer:

x=3+√23 or x=3−√23= 1.79

Novay_Z [31]

Answer:

  • Annabella will save $4950.11 after 2 years.

Step-by-step explanation:

<h3>Given</h3>

  • Periodic payment P = $200,
  • Period t = 2 years,
  • Number of compounds, monthly n = 12,
  • Interest rate, r = 3.2% = 0.032.

<h3>To find</h3>

  • Future value of saving, F

<h3>Solution</h3>

Use periodic compound formula:

F=P\cfrac{(1+r/n)^{nt}-1}{r/n}

Substitute the values and calculate:

F=200\cfrac{(1+0.032/12)^{12*2}-1}{0.032/12} =4950.12     rounded

Step-by-step explanation:

A case of paper cups costs $408 / 17 = $24.

5 more cases => 22 cases of paper cups total.

Hence the total cost will be 22 * $24 = $528.

Step-by-step explanation:

fg(x)=f[g(x)]

=f(-4x+7)

=3(-4x+7)+5

=-12x+26

When x=-4,

fg(-4)=-12(-4)+26

=74

Decide whether the pair of lines is parallel, perpendicular, or neither.
maw [93]

The lines are:  B) Perpendicular

Step-by-step explanation:

we have to convert both lines in slope-intercept form to find slopes

So,

3x - 6y = -13\\-6y = -3x-13\\\frac{-6y}{-6} = \frac{-3x-13}{-6}\\\frac{-6y}{-6} = \frac{-3x}{-6}+\frac{-13}{-6}\\y = \frac{1}{2} +\frac{13}{6}

Let m1 be the slope of first line

m_1 = \frac{1}{2}

For the second line:

18x + 9y = 5\\9y = -18x+5\\\frac{9y}{9} = \frac{-18x+5}{9}\\\frac{9y}{9} = \frac{-18}{9}x+\frac{5}{9}\\y = -2x+\frac{5}{9}

Let m2 be the slope of line 2

So,

If the lines are parallel, their slopes are equal

If the lines are perpendicular, product of their slopes is -1

We can see that

\frac{1}{2} * -2 = -1

Hence,

The lines are:  B) Perpendicular
