Pi typically looks like a cursive "r" or a bench of some sort, so I believe this is the pi symbol. Hope that helps :)

The solution of the logarithmic equation provided using the log rule is,

[tex]x=-3[/tex]

When the base of the logarithm in an equality expression is same, then the number are directly compared to each other.

The given logarithmic equation in the problem is,

[tex]\log_7(x -4) = \log_7(4x +5)\\[/tex]

Compare the number for the same base as,

[tex](x-4)=(4x+5)[/tex]

Solve the equation further as,

[tex]4x-x=-4-5\\3x=-9\\x=\dfrac{-9}{3}\\x=-3[/tex]

Thus, the solution of the logarithmic equation provided using the log rule is,

[tex]x=-3[/tex]

Step-by-step explanation:

52 weeks in a year then multiply 15.40

Answer:

$803

Step-by-step explanation:

cost of electricity for 1 week = 15.40

⇒ cost of electricity for 1 day = 15.40 ÷ 7 = 2.20

⇒ cost of electricity for 365 days = 2.20 x 365 = 803

Answer:

p = 4

Step-by-step explanation:

3p + 8 = 20

3p = 20 - 8

3p = 12

p = 12/3

p = 4

Answer:

see below

Step-by-step explanation:

2p + 8 = 20 - p

add p to both sides

2p + p + 8 = 20 - p + p

combine like terms

3p + 8 = 20

subtract 8 from both sides

3p + 8 - 8 = 20 - 8

combine like terms

3p = 12

divide both sides by 3

3p / 3 = p

12/3 = 4

we're left with p = 4

Answer:

CDA≈27,6°

Step-by-step explanation:

First we solve the x using pythagorean theorem

a^2+b^2=c^2

x^2+6^2=6.5^2

x^2+36=42.25      ||-36

x^2=42.25-36

x^2=6.25               ||√

√x^2=√6.25

x=2.5cm

now we can solve y

y = 23cm-9cm-2.5cm

y=11.5cm

now we can solve CDA angle with tanα

tanα=[tex]\frac{a}{b} \\[/tex]

tanα=6cm/11.5cm

α≈27,6°

Step-by-step explanation:

Answer:

19w + 3

Explanation:

perimeter: length measure of all sides

perimeter for this shape:

→ 4w + 4 + 6w + 5 + 7w + 3 + 2w - 9

group terms like this ↓

→ 4w + 6w + 7w + 2w + 4 + 5 + 3 -9

add basic numbers ↓

→ 4w +6w +7w +2w +3

final answer ↓

→ 19w + 3

Perimeter is the sum of all the sides.

2w-9 + 4w + 4 + 6w + 5 + 7w + 3

Combine like terms:

19w + 3

Degree of a polynomial gives the highest power of its terms. Yes there is a difference between the degrees of sum and difference of the polynomials.

Degree of a polynomial is the highest power that its terms pertain(for multi-variables, the power of term is addition of power of variables in that term).

Thus, in [tex]x^3 + 3x^2 + 5[/tex], the degree of the polynomial is 3 as the highest power in its terms is 3.

(power and exponent are same thing)

Those terms which have same variables raised with same powers.

For example, [tex]x^3[/tex] and [tex]3x^3[/tex]  are like terms since variable is same, and it is raised to same power 3.

For example [tex]4x^2[/tex] and [tex]x^3[/tex] are not like terms as the variables are same but powers aren't same.

The given polynomials are:

[tex]c(x) = x^7 + 3x^5 + 3x + 1\\\\p(x) = x^7 + 5x + 10[/tex]

Their sum is

[tex]c(x) + p(x) = x^7 + 3x^5 + 3x + 1 + x^7 + 5x + 10 = (1+1)x^7 + 3x^5 + (3+5)x + 11\\\\c(x) + p(x) = 2x^7 + 3x^5 + 8x + 11[/tex]

(only like terms' coefficients can be added (or subtracted) for addition or subtraction of them )

The sum's degree is 7

Their difference is:

[tex]c(x) - p(x) = x^7 + 3x^5 + 3x + 1 - x^7 -5x - 10 = (1-1)x^7 + 3x^5 +(3-5)x -9\\\\c(x) - p(x) = 3x^5 - 2x - 9[/tex]

Difference's degree is 5

Thus, both's degrees are not same.

Thus, Yes there is a difference between the degrees of sum and difference of the polynomials.

Answer: 12 yearly admissions and 38 single admissions

Step-by-step explanation:

Let x be yearly membership

Let y be single admission

x+y=50 --> # of tickets sold

35.25x+6.25y=660.50 --> $ of tickets

Use elimination method to solve (multiply equation 1 by -3525 and equation 2 by 100)

-3525x-3525y=-176250

+  3525+625y=66050

-----------------------------------

-2900y=-110200

y=38

Substitute y=38 into equation 1

x+38=50

x=12

Therefore, 12 yearly admissions and 38 single admissions were sold
