The total cost of 2 novels and 4 fiction books is $84. Each novel costs $6 more than each fiction book. What is the total cost o
zhuklara [117]

Answer:

$30

Step-by-step explanation:

Let,

  x - fiction book

  x + $6 - novel

EQUATION:

  4(x) + 2(x + $6) = $84

  6x + $12 = $84

  6x = $84 - $12

  6x = $72

  x = $12

SUBSTITUTE:

    novel = $12

    fiction = $18

TOTAL COST OF NOVEL AND FICTION

$18 + $12 = $30

The motion of a ship riding at anchor can be modeled by y=25-4 cos (pi/6)t, where y is the water depth in feet and t is the time
balandron [24]

Answer: 29 feet (deepest) at 6 am

              21 feet (shallowest) at Midnight & Noon

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

y = -4 cos (π/6)t +25

Amplitude (A) = 4    

-A means it is a reflection over the x-axis (starts at minimum)<em> </em>

Period = 2π/B   →  Period = 12

Phase shift = C/B   →  Phase Shift = 0

Midline (D) = 25

Midline (D) ± Amplitude (A) = Max & Min

Max: 25 + 4 = 29

Min: 25 - 4 = 21

Change the coordinates of y = cos (x) as follows:

  • x-value: Add C then divide by B
  • y-value: Multiply by A then add D

Note that the equation shows: A = -4, B = π/6, C = 0, D = 25

\begin{array}{c|ccc|cl}\underline{\quad x\quad}&\underline{\quad y\quad}&&\underline{\quad (x+C)/B\quad}&\underline{\quad Ay+D\quad}\\0&1&&0&21&minimum\\\pi&0&&3&25&midline\\\pi &-1&&6&29&maximum\\3\pi/2&0&&9&25&midline\\2\pi&1&&12&21&minimum\\\end{array}

Answer:

True

Step-by-step explanation:

That expression is called the "Quadratic formula" and basically the solution to any second degree equation can be find by using the quadratic formula.

Attached you can find the procedure to get to the quadratic formula from the general equation of a second degree polynomial.
