Form an equation whose roots are 2 and -4/3

Answer:

Complementary angles means sum of angles must to 90 degrees.

Supplementary angles means sum of angles must be 180 degrees.

1.

10 degree + 65 degree = 75 degree

   10 degree + 65 degree ≠ 90 degree

So, 10-degree angle and a 65-degree angle are

not complementary angles.

2.

40 degree + 50 degree = 90 degree

So, 40-degree angle and a 50-degree angle are

complementary angles.

3.

140 degree + 40 degree = 180 degree

So, 140-degree angle and a 40-degree angle are

supplementary angles.

4.

120 degree + 60 degree = 180 degree

120 degree + 60 degree ≠ 90 degree

So,120-degree angle and a 60-degree angle are

not complementary angles

Answer:

10 ft to nearest foot.

Step-by-step explanation:

We use the Pythagoras theorem:

12^2 = 6^2 + h^2    where h is the height on the barn

h^2 = 12^2 - 6^2

h^2 = 144 - 36 = 102

h= √108 = 10.39

The cost per cookie, in dollars, for a sugar cookie is A; $0.54.

The mean is the average value which can be calculated by dividing the sum of observations by the number of observations

Mean = Sum of observations/the number of observations

WE know that Chocolate chip = $0.73

Double chocolate = $0.82

Oatmeal raisin = $0.70

Sugar = X

Butter pecan = $0.86

We need to find the  cost per cookie, in dollars, for a sugar cookie.

So, Mean = $0.73

Mean = 0.73 + 0.82 + 0.70+ X + 0.86 / 5

0.73 (5) =0.73 + 0.82 + 0.70+ X + 0.86

x = 0.54

Therefore, The cost per cookie, in dollars, for a sugar cookie is A; $0.54.

Step-by-step explanation:

Since it is a right-angled triangle, we will apply Pythagoras Theorem.

Given are:

Base = 16

Perpendicular = x

Hypotenuse = 18

Pythagoras Theorem:

[tex]\sf (Hypotenuse)^2=(Base)^2+(Perpendicular)^2[/tex]

(18)² = (16)² + (x)²

324 = 256 + x²

Subtract 256 to both sides

324 - 256 = x²

68 = x²

Take sqrt on both sides

Answer:

15° and 75°

Step-by-step explanation:

The sum of the measures of complementary angles is 90.

Angle 1 measures x.

Angle 2 measures x + 60.

Their sum is 90.

x + x + 60 = 90

2x + 60 = 90

2x = 30

x = 15

x + 60 = 75

Answer:

See Below

Step-by-step explanation:

Initial cost = $52

Markup for operating expenses = 34%

$52 + 34% = $52*1.34 = $69.68

Markup for profit = 6%

69.68 + 6% = 69.68*1.06 = 73.86 (rounded)

a) The selling price is $73.86

b) The reduced price is:

$73.86 - $25 = $48.86

c) The percent of markdown:

25/73.86*100% = 33.85% (rounded)

d) The absolute loss:

$69.68 - $48.86 = $20.82

Answer:

Step-by-step explanation:

Answer:

Below in bold

Step-by-step explanation:

The sequence is:

3, x, y, 18

If this is an A P then

x - 3 = y - x  

2x - y = 3      (A)  and

y - x = 18 - y

2y - x = 18      (B)

Multiply  (A) by 2:

4x - 2y = 6    (C)

Adding B and C:

3x = 24

x = 8.

and

2y - 8 = 18

2y = 26

y = 13.

So x = 8 and y = 13.

b)   ar + ar^2 = 6ar^3  where a = first term and r = common ratio

Divide by a:

r + r^2 = 6r^3

6r^3 - r^2 - r = 0

r(6r^2 - r - 1) = 0

r(3r  + 1)(2r  - 1) = 0

So the 2 possible values of r

= -1/3 and 1/2.

i) The common ratio is positive so it must be 1/2.

Second term ar = 8

1/2 a = 8

a = 16.

So the first 6 terms are:

16, 8, 4, 2, 1, 1/2.
