Solve the equation.
p2 - 10p + 21 = 0

Answer:

29, 26, 21, 14, 5

Step-by-step explanation:

To find the first 5 terms, substitute n = 1, 2, 3, 4, 5 into the n th term formula.

30 - 1² = 30 - 1 = 29

30 - 2² = 30 - 4 = 26

30 - 3² = 30 - 9 = 21

30 - 4² = 30 - 16 = 14

30 - 5² = 30 - 25 = 5

The first 5 terms are 29, 26, 21, 14, 5

Answer:

−28hw+9w+3

Step-by-step explanation:

5w(1-8h) = 5w-40wh

+12wh = -28hw

-28hw+5w+5w = -28hw+10w

-w = -28hw+9w

+3 = -28hw+9w+3

Answer:

0.42

Step-by-step explanation:

given:

P (penny) = 1/4

P (dime) = 1/3

since the only other possibility is to pick a nickel, hence

P (nickel)

= 1 - 1/4  - 1/3

= 5/12

= 0.4166667

= 0.42 (nearest hundredth)

Answer:

Equation of the ellipse = 3x² + 5y² = 32

The equation of an ellipse is given by,

[tex]\sf \dfrac{x^2}{a^2} +\dfrac{y^2}{b^2} =1[/tex]

Given that the ellipse passes through the point (-3, 1)

Hence,

[tex]\sf \dfrac{(-3)^2}{a^2} +\dfrac{1^2}{b^2} =1[/tex]

Cross multiplying we get,

Multiply by 4 on both sides,

Also by given the ellipse passes through the point (2, -2)

Substituting this,

[tex]\sf \dfrac{2^2}{a^2} +\dfrac{(-2)^2}{b^2} =1[/tex]

Cross multiply,

Subtracting equations 2 and 1,

Substituting in 2,

Substituting the values in the equation for ellipse,

[tex]\sf \dfrac{x^2}{32/3} +\dfrac{y^2}{32/5} =1[/tex]

[tex]\sf \dfrac{3x^2}{32} +\dfrac{5y^2}{32} =1[/tex]

Multiplying whole equation by 32 we get,

3x² + 5y² = 32

Answer:

Step-by-step explanation:

Add 6 to both sides.

3m−6+6=33+6

3m=39

Divide both sides by 3.

3m/ 3 = 39 /3

m=13

Answer:

Step-by-step explanation:

[tex]step - 1 : define[/tex]

[tex]3m-6=33[/tex]

[tex]step - 2 : \\ add \: 6 \: to \: both \: sides[/tex]

[tex]3x - 6 + 6 = 33 + 6[/tex]

[tex]3x = 39[/tex]

[tex]step - 3 : \\ divide \: both \: sides \: by \: 3[/tex]

[tex] \frac{3x}{3} = \frac{39}{3} [/tex]

[tex] \huge\therefore \: x = 13[/tex]

      5+3

B)

3b/7 - 1 = 5

Add 1 in both sides

3b/7 - 1 + 1 = 5 + 1

3b/7 = 6

Multiply both sides by 7 and then divide by 3.

3b/7 . 7/3 = 6 . 7/3

b = 2.7

Answer:

25%

Step-by-step explanation:

Divide 89.99 or 90 (since you are rounding) by 120, and you get .7499 or 75%.  You have 25% ($30) as the discount because 90 is 75% of $120.

Answer:

Please check the explanation.

Step-by-step explanation:

We know that a pentagon is a polygon with 5 sides and 5 angles.

Given the polygon with 5 angles.

A pentagon is a polygon with 5 sides and 5 angles.

The angles of the given pentagon are:

∠P = (4x + 2)°

∠Q = 132°

∠R = (4x - 10)°

∠S = (5x - 11)°

∠T = 128°

We know that the sum of the measures of the interior angles of a pentagon is 540 degrees.

Therefore,

∠P + ∠Q + ∠R + ∠S + ∠T = 540°

(4x + 2)° + 132° + (4x - 10)° + (5x - 11)° + 128° = 540°

group similar elements

4x + 4x + 5x + 2 + 132 - 10 - 11 + 128 = 540

simplify

13x + 241 = 540

subtract 241 from both sides

13x + 241 - 241 = 540 - 241

13x = 299

divide both sides by 13

13x/13 = 299/13

x = 23

Thus, the value of x = 23

Therefore, the measure of angle ∠S is:

m∠S = (5x - 11)°

        = (5(23) - 11)°

        = (115 - 11)°

        = 104°

Thus,

m∠S = 104°
