a
The prediction was off 35%
b
The percent error of the prediction was about 55%.

Answer:

$ 74.80

Step-by-step explanation:

The subtotal cost of the meal was $91.22  including tax.

The 18% tip is added for six or more.

The tip added should reduce the meal subtotal by 18 %

Reduce $91.22 by 18%  to get ;

82/100 * 91.22 = $ 74.80

Answer:

1) The slope of the line segment AB is [tex]\frac{4}{3}[/tex].

2) The length of the line segment AB is 10.

3) The coordinates of the midpoint of the line segment AB is [tex]M(x,y) = (5,7)[/tex].

4) The slope of a line perpendicular to line segment AB is [tex]-\frac{3}{4}[/tex].

Step-by-step explanation:

1) Let [tex]A(x,y) = (2,3)[/tex] and [tex]B(x,y) = (8,11)[/tex]. From Analytical Geometry, we get that slope of AB ([tex]m_{AB}[/tex]), dimensionless, is determined by the following formula:

[tex]m_{AB} = \frac{y_{B}-y_{A}}{x_{B}-x_{A}}[/tex] (1)

If we know that [tex]x_{A} = 2[/tex], [tex]x_{B} = 8[/tex], [tex]y_{A} = 3[/tex] and [tex]y_{B} = 11[/tex], the slope of the line segment is:

[tex]m_{AB} = \frac{11-3}{8-2}[/tex]

[tex]m_{AB} = \frac{4}{3}[/tex]

The slope of the line segment AB is [tex]\frac{4}{3}[/tex].

2) The length of the line segment AB ([tex]l_{AB}[/tex]), dimensionless, can be calculated by the Pythagorean Theorem:

[tex]l_{AB} =\sqrt{(x_{B}-x_{A})^{2}+(y_{B}-y_{A})^{2}}[/tex] (2)

If we know that [tex]x_{A} = 2[/tex], [tex]x_{B} = 8[/tex], [tex]y_{A} = 3[/tex] and [tex]y_{B} = 11[/tex], the length of the line segment AB is:

[tex]l_{AB} = \sqrt{(8-2)^{2}+(11-3)^{2}}[/tex]

[tex]l_{AB} = 10[/tex]

The length of the line segment AB is 10.

3) The coordinates of the midpoint of the line segment AB are, respectively:

[tex]x_{M} = \frac{x_{A}+x_{B}}{2}[/tex] (3)

[tex]y_{M} = \frac{y_{A}+y_{B}}{2}[/tex] (4)

If we know that [tex]x_{A} = 2[/tex], [tex]x_{B} = 8[/tex], [tex]y_{A} = 3[/tex] and [tex]y_{B} = 11[/tex], the coordinates of the midpoint of the line segment AB are, respectively:

[tex]x_{M} = \frac{2+8}{2}[/tex]

[tex]x_{M} = 5[/tex]

[tex]y_{M} = \frac{3+11}{2}[/tex]

[tex]y_{M} = 7[/tex]

The coordinates of the midpoint of the line segment AB is [tex]M(x,y) = (5,7)[/tex].

4) From Analytical Geometry we can determine the slope of a line perpendicular to line segment AB as a function of the slope of the line segment:

[tex]m_{\perp} = -\frac{1}{m_{AB}}[/tex] (5)

If we know that [tex]m_{AB} = \frac{4}{3}[/tex], then the slope of a line perpendicular to AB is:

[tex]m_{\perp} = - \frac{1}{\frac{4}{3} }[/tex]

[tex]m_{\perp} = -\frac{3}{4}[/tex]

The slope of a line perpendicular to line segment AB is [tex]-\frac{3}{4}[/tex].

4

Step-by-step explanation:

so the slope equation is y2-y1 over x2-x1 so by that logic 11-7 =4 and 4-3= 1 therefore it would equal all to 4 over 1 and by dividing that you get 4.

Step-by-step explanation:

Angle ADB = Angle CBD = 90° (given)

Side AB = Side DC (given)

Common side DB / BD

By HL congruence, triangles ABD and CDB are congruent.

Therefore Angle ABD = Angle CDB

=> Line AB is parallel to Line DC (Z angles)

Answer:

  17 years

Step-by-step explanation:

The formula for the value of an account earning compound interest can be used to find the number of years. That formula is ...

  A = P(1 +r/n)^(nt)

where P is the principal invested at annual rate r compounded n times per year for t years.

__

Solving for t, we find ...

  A/P = (1 +r/n)^(nt) . . . . . . divide by P

  log(A/P) = nt·log(1 +r/n) . . . . take logarithms

  t = log(A/P)/(n·log(1 +r/n)) . . . . . divide by the coefficient of t

For the given values, the time required is ...

  t = log(1740/670)/(365·log(1 +0.055/365)) ≈ 17.353

It would take about 17 years for the account value to reach $1740.

Additional comment

The time-value-of-money (TVM) apps of your calculator or spreadsheet can be used to find the time period of interest. Here, setting P/Y = 1 gives N in years.

Step-by-step explanation:

8-3 = 5

5x5 = 25

25 / 25 = 1

1 - 1 = 0

and 81 / 9 x 4 = 9 x 4 = 36

Answer:

0 and 36

Step-by-step explanation:

16

25 ÷ (8 - 3)² - 1 ← evaluate parenthesis

= 25 ÷ 5² - 1 ← evaluate exponent

= 25 ÷ 25 - 1 ← evaluate division

= 1 - 1

= 0

Answer:

  rotated vertices are (1, 1), (-2, -1), (-4, 0)

Step-by-step explanation:

When the rotation direction is not specified, it is usually taken to be counterclockwise. Rotation 270° CCW is the same as rotation 90° CW. The transformation of coordinates is ...

  (x, y) ⇒ (y, -x)

Then your rotated points become ...

  A(-1, 1) ⇒ A'(1, 1)

  B(1, -2) ⇒ B'(-2, -1)

  C(0, -4) ⇒ C'(-4, 0)
