Answer:

1) (1/3)log_7(10); 3) log_8(u) - log_8(v); 5) 3ln(x)

Step-by-step explanation:

1)

log_7(^3sqrt(10))

log_7(10^1/3)

log_a(x^b) = b * log_a(x); when x >= 0.

(1/3)log_7(10)

About 0.39443...

3)

log_8(u/v)

log_c(a/b) = log_c(a) - log_c(b)

log_8(u) - log_8(v)

5)

ln(x^3)

log_a(x^b) = b * log_a(x); when x >= 0.

3ln(x)

Answer:

a-10 - 6/a+2

Step-by-step explanation:

The simplification of the expression (a²- 8a - 26) / (a + 2) is (a - 10) - 6/(a + 2).

The number system is a way to represent or express numbers.

A decimal number is a very common number that we use frequently.

Since the decimal number system employs ten digits from 0 to 9, it has a base of 10.

As per the given b,

(a²- 8a - 26) / (a + 2)

First quotient = a

Remainder = -10a - 26

Second quotient = -10

Remainder = -6

By quotient remainder theorem,

(a²- 8a - 26) = (a + 2)(a - 10) - 6

Thus,

[(a + 2)(a - 10) - 6]/(a + 2) = (a - 10) - 6/(a + 2)

Hence "The simplification of the expression (a²- 8a - 26) / (a + 2) is (a - 10) - 6/(a + 2)".

Answer:

Step-by-step explanation:

Perimeter of the deck = (d + 5) + (d + 5) + (d + 5) + (d + 5)

1). By grouping method,

    Perimeter = (d + d + d + d) + (5 + 5 + 5 + 5)

2). Perimeter = Number of sides × Length of a side

                       = 4(d + 5)

3). Expression from problem 1,

    Perimeter = (d + d + d + d) + (5 + 5 + 5 + 5)

                      = 4d + 20

                      = 4(d + 5)

    Expression from problem 2,

    Perimeter = 4(d + 5)

    Bot the expressions are same.

Answer:

distance = 10.6

Step-by-step explanation:

A's coords are (5, 6)

D's coords are (-2, -2)

So the total horizontal distance between A and D is:

5 + 2 = 7

...and the total vertical distance is:

6 + 2 = 8

Now use Pythagorean Theorem:

7^2 + 8^2 = distance^2

distance^2 = 49 + 64 = 113

distance = squareroot of 113

distance = 10.6

Answer:

X = 70, y = 21

Step-by-step explanation:

53 + 6y + 1 = 6y + 54

6y + 54 = 180

180 - 54 = 126

6y = 126

126 ÷ 6 = 21

Y = 21

21 × 6 + 1 = 127

127 = 2x - 13

127 + 13 = 140

140 ÷ 2 = 70

X = 70

Opposite angles are congruent and consecutive angles are supplementary.

Answer:

y < 14/3

Step-by-step explanation:

You can immediately negate the negative from both sides by canceling the -1.

Divide both sides by 3, when you divide a < or > by anything you have to switch the sign it faces. So in this case

-3y > -14

=> 3y < 14

y < 14/3

Step-by-step explanation:

The question is not complete.

Let us assume that the black square rotates in a circular part of radius 1 inch.

Therefore, in one full rotation the distance covered (θ) is the same as the perimeter of the circular part. Therefore:

θ = 2πr = 2π(1) = 6.28 inch

The time taken to complete one full rotation (t) is:

t = θ / v

t = 6.28 / 2

t = 3.14 seconds

Answer:

45 Degrees

Step-by-step explanation:

This would be a right angle. The other side would be 45 Degrees. Which when you add them equals 90.

Answer:

45 degrees

Step-by-step explanation:

The following figure shown is a square

All of the angles in a square are right angles meaning that they equal 90

If a diagonal line cuts through the middle then it splits the right angle into to 45 degree angles therefore your answer is 45 degrees

Answer:

4¹⁰

Step-by-step explanation:

You don do the figuring out want number is in each exponent you simply add because you have the same base and if its multiplication you actually do addition in which multiplication is repeated addition. same for division but subtraction instead because you are lowing the number :)

Answer:

2280

Step-by-step explanation:

As in understandable steps,

1512x12 = 18144

18144 / 7

= 2592

2592 - 312

= 2280

An equation is formed of two equal expressions. John's salary before the pay raise is $2280.

An equation is formed when two equal expressions are equated together with the help of an equal sign '='.

Let the pay of John before the raise be x.

As it is stated that John's pay was increased by $312. And he saves 7/12 of his pay which is equal to $1512. Therefore, the equation that can represent the current saving John has,

[tex]\dfrac{7}{12}(x+312)=1512\\\\(x+312) = \dfrac{1512 \times 12}{7}\\\\x+312= 2592\\\\x =2592-312\\\\x = 2280[/tex]

Hence, John's salary before the pay raise is $2280.
