The expression [tex]3log_b(8) - log_b(7)[/tex] written as a single logarithm is [tex]log_b(\frac{512}{7})[/tex].
How to turn expressions into a single logarithm?Given the logarithmetic expression in the question:
[tex]3log_b(8) - log_b(7)[/tex]
To rewrite the expression [tex]3log_b(8) - log_b(7)[/tex] as a single logarithm, we can use the properties of logarithms.
Using the quotient rule property, which states that:
logₙ(a) - logₙ(b) = logₙ(a/b)
Applying the quotient rule:
First, rewrite [tex]3log_b(8) - log_b(7)[/tex] as:
[tex]log_b(8^3) - log_b(7)[/tex]
Now, since the base of the logarithm is the same (b), we can combine the two logarithms using the power rule, which states that logₙ(aᵇ) = b × logₙ(a).
[tex]log_b(\frac{8^3}{7})[/tex]
Simplify
[tex]log_b(\frac{512}{7})[/tex]
Therefore, the single logarithm is [tex]log_b(\frac{512}{7})[/tex].

7. 14476.46 mm³
8. 3744 ft³
9. 473.6mm³
10. 18816.57cm³
How to determine the volume
To determine the values, we need to know the following;
Area of circle = π r ²Circumference = π X D (D = diameter = 2 X radius)Volume of sphere = (4/3) X π X r ³Volume of prism = area of cross-section X lengthVolume of cylinder (questions 6 and 7 are cylinders) = π r ² hIn a right-angled triangle, a ² + b ² = c ²
Now. for each of the shapes, substitute the values, we have;
6) π (16) ² X 14
Multiply the values
= 11259.47 in³
7) Diameter² = 40² - 32²
Diameter = √(40² - 32²) = 24, Radius = 12.
Substitute the values
Volume = π (12)² X 32 = 14476.46 mm³
8) volume = 8 X 12 X 39
Multiply the values
= 3744 ft³
9) cross-section (triangle) = 1/2 X 5.4 X 11 = 29.7
Volume = 29.7 X 16 = 473.6mm³

Find The perimeter of an equilateral triangle Of edge 4.24 cm
The required perimeter of the equilateral triangle is 12.72 cm.
An equilateral triangle has all three sides equal in length. Therefore, if the edge of an equilateral triangle is 4.24 cm, then all three sides are 4.24 cm.
To find the perimeter of the equilateral triangle, we need to add the length of all three sides together:
Perimeter = 4.24 cm + 4.24 cm + 4.24 cm
Perimeter = 12.72 cm
Therefore, the perimeter of the equilateral triangle is 12.72 cm.

The value of the missing side length x in the right triangle is 15 inches.
What is the value of x?Pythagorean theorem states that the "square on the hypotenuse of a right-angled triangle is equal in area to the sum of the squares on the other two sides.
It is expressed as;
( hypotenuse )² = ( leg 1 )² + ( leg 2 )²
The image in the diagram is a right triangle:
Hypotenuse = 17 inches
Leg 1 = 8 inches
Leg 2 = x
To solve for x, we use the pythagorean theorem.
( hypotenuse )² = ( leg 1 )² + ( leg 2 )²
( leg 2 )² = ( hypotenuse )² - ( leg 1 )²
( leg 2 )² = ( 17 )² - ( 8 )²
( leg 2 )² = 289 - 64
( leg 2 )² = 225
Take the square roots
Leg 2 = √225
Leg 2 = 15 inches.

What is the measure of the angles of the polygon?
The measure of the angles of the polygon is calculated as follows;
The following angles were given;
angle 3 = 60⁰
angle 8 = 135⁰
The following angles can be determined as follows;
angle 5 = 180 - 60⁰ ( sum of angles on a straight line )
angle 5 = 120⁰
angle 7 = angle 3 = 60⁰ (corresponding angles )
angle 5 = angle 1 = 120⁰ (corresponding angles )
The value of angle 6 is calculated as;
∠5 + ∠6 + ∠7 + ∠8 = 360 (sum of angles in quadrilateral)
120 + ∠6 + 60 + 135 = 360

(b) The graph of is shown. Translate it to get the graph of .
look at picture
The graph of the translations are attached
The red is the preimage while the blue is the image
How to complete the translation
The absolute value graph has equation f(x) = |2x| and the translation we want to obtain is y = f(x) + 4 and this is a translation 4 units up
This results to a graph of equation y = f(x) + 4 = |2x| + 4
For the parabolic graph, the equation is written as
y = a(x - 2)² - 3
solving for a using (0, -5)
-5 = a(0 - 2)² - 3
-2 = 4a
a = -1/2, then the equation is g(x) = -1/2 (x - 2)² - 3
Applying the translation, the equation will be
y = g(x + 2) = -1/2 (x - 2 + 2)² - 3 = -1/2 (x)² - 3

Sin(3π/2+x)+sin(3π/2+x)=2
The solutions to the original equation are:
x = π - 3π/2 = -π/2
x = 3π/2 - 3π/2 = 0
So the values of x that satisfy the equation are -π/2 and 0.
To solve the given equation, we can use the following trigonometric identity:
sin(A) + sin(B) = 2*sin((A+B)/2)*cos((A-B)/2)
Applying this identity to sin(3π/2+x) + sin(3π/2+x), we get:
sin(3π/2+x) + sin(3π/2+x) = 2*sin((3π/2+x + 3π/2+x)/2)cos((3π/2+x - 3π/2+x)/2)
= 2sin(3π/2+x)cos(0)
= 2(-cos(x))
Therefore, the equation can be simplified to:
-2*cos(x) = 2
Dividing both sides by -2, we get:
cos(x) = -1
This means that x is either π or 3π/2, since those are the values where cos(x) = -1.

Find the equation of degree 3 polynomial function with real coefficients having zeros x = - 2 with multiplicity 2 and x = 3 with multiplicity 1. The function passes through the point (1, 54)
The equation of the polynomial is f ( x ) = -13.5 ( x + 2 )²( x - 3 )
Given data ,
The equation of degree 3 polynomial function with real coefficients
And , zeros x = - 2 with multiplicity 2 and x = 3 with multiplicity 1
where function passes through the point (1, 54)
If a polynomial function has a zero x = a with multiplicity k, then the factor (x - a)^k appears in its factored form.
Therefore, a degree 3 polynomial function with zeros x = -2 with multiplicity 2 and x = 3 with multiplicity 1 can be written in factored form as:
f(x) = a(x + 2)²(x - 3)
where a is a constant factor. To find the value of a, we use the fact that the function passes through the point (1, 54):
f(1) = a(1 + 2)²(1 - 3) = 54
a(-1)²(-2) = 54
-4a = 54
Divide by -4 on both sides , we get
a = -13.5
Hence , the equation of the degree 3 polynomial function with the given zeros and passing through the point (1, 54) is f ( x ) = -13.5 ( x + 2 )²( x - 3 )

Two burgers and one hotdog cost $4.82. At the same price, one burger and two hotdogs cost $3.70. How much does a hotdog cost?
Answer:
Hope this helps ^^
Step-by-step explanation:
Let's define the variables:
Let's call the cost of a burger "B" (in dollars).
Let's call the cost of a hotdog "H" (in dollars).
Now, we can set up a system of equations based on the given information:
Equation 1: 2B + H = 4.82 (Two burgers and one hotdog cost $4.82)
Equation 2: B + 2H = 3.70 (One burger and two hotdogs cost $3.70)
To solve this system of equations, we can use the method of substitution or elimination.
Using the method of elimination, we can multiply Equation 2 by 2 to eliminate the "B" term:
2(B + 2H) = 2(3.70)
2B + 4H = 7.40
Now, we can subtract Equation 1 from this new equation to eliminate the "2B" term:
(2B + 4H) - (2B + H) = 7.40 - 4.82
2H - H = 2.58
H = 2.58
Therefore, the cost of a hotdog is $2.58.
Labeling the answer: The cost of a hotdog is $2.58.

Find the quotient and remainder using synthetic division.
x^4-3x^3+9x+6/x+1
The quotient is
The remainder is
Answer:
Step-by-step explanation:
To use synthetic division, we need to set up the coefficients of the dividend polynomial in decreasing order of powers of x, including any missing terms with zero coefficients.
So we have:
Dividend: x^4 - 3x^3 + 9x + 6
Divisor: x + 1
We can represent the divisor as (x + 1) and set up the synthetic division table as follows:
-1 | 1 -3 9 0 6
| -1 4 -13 13
|___________________
| 1 -4 13 -13 19
The numbers on the first row of the table are the coefficients of the dividend polynomial in decreasing order of powers of x. The -1 on the left of the table is the opposite of the divisor, x + 1.
The first number in the second row is always 0, and we get it by bringing down the first coefficient, which is 1. To get the next number in the second row, we multiply the divisor, -1, by 1, and add the result to the second coefficient, which is -3. This gives us -1 x -3 = 3, which we write under -3 in the first row.
We repeat this process for the next numbers in the second row, always multiplying the divisor by the last number in the second row, and adding the result to the next coefficient in the first row. We continue until we reach the last coefficient in the first row.
The last number in the second row, 13, is the remainder of the division. The other numbers in the second row are the coefficients of the quotient polynomial in decreasing order of powers of x. So the quotient is:
x^3 - 4x^2 + 13x - 13
And the remainder is:
13
Therefore, the quotient is x^3 - 4x^2 + 13x - 13, and the remainder is 13.
