Expand the logarithm. log4 (3xyz)^2
Answer:
Answer is (2log2 + 2log3 + 2logx + 2logy + 2logz)
Step-by-step explanation:
log4(3xyz)²
= log4 + log(3xyz)²
= log4 + 2log(3xyz)
= log(2)² + 2[log3 + logx + logy + logz]
= 2log2 + 2log3 + 2logx + 2logy + 2logz

Tangent is a straight line that touches the circle at any point on the curve. The measure of ∠DQM in ΔDQM is 40º.
What is a tangent?A tangent is a straight line that touches the circle at any point on the curve. And the angle made by the tangent with radius is always 90°.
We know that line AD is the tangent to circle M, and line MD is the radius of the circle, therefore, the measure of ∠ADM is 90°.
Now, In ΔDQM, the measure of ∠DMQ is 50º, while the measure of ∠MDQ is 90º. therefore, the sum of all the angles of the ΔDQM can be written as,
[tex]\angle DQM + \angle MDQ + \angle DMQ = 180^o\\\\\angle DQM + 90^o + 50^o = 180^o\\\\\angle DQM = 180^o -90^o -50^o\\\\\angle DQM = 40^o[/tex]
Hence, the measure of ∠DQM is 40º.

The number of visitors to a park is expected to follow the function v(x) = 7(x − 1), where x is the number of days since opening. On the first day, there will be a ceremony with 39 people in attendance. What is the function that shows total visitors, including the ceremony?
c(x) = 7(x − 1) − 39
c(x) = 39x − 7
c(x) = 39 − 7(x − 1)
c(x) = 39 + 7(x − 1)
The answer is D. c(x) = 39 + 7(x - 1)

What is the value of x?
The value of x can signify diverse number based on the context it is applied in. For instance, it can be a certain range of values, part of a chemical equation, or the result of a mathematical equation. Therefore, the value of x is determined by the given conditions.
Explanation:The value of x can be discovered through various mathematical processes depending on the context. In the examples given, x was used to denote different values across multiple scenarios.
One situation presented x as a value that ranged from 1.5 to 4.5, indicated by 1.5 ≤ x ≤ 4.5. In another instance, x was determined by the concentration of hydroxide ions in a chemical equation, which resulted in x = 4.0 × 10-³ M. Furthermore, x was also inferred from a quadratic equation where it implied the hydronium concentration.
In summary, the value of x varies based on the mathematical or scientific context it is applied to, and its value must be determined through specified conditions or equations.

Kareem wants to wallpaper the back wall of his bedroom. The wall is in the shape of a rectangle. Its length is
13 feet and its width is 12
feet. The wallpaper costs $8
for each square foot. How much will wallpaper cost for the wall?
The first step in solving this problem is to compute for the area of the rectangular wall. The formula in computing the area of a rectangle is:
A = LW
Substituting the given measurements in the problem to the formula:
A = 13 (12)
A = 156
Therefore, the area of the wall is 156 square feet. To compute the wallpaper cost of the wall, you have to multiply the cost per square foot to the total area.
$8 per square foot x 156 square feet = $1,248
Therefore, the wallpaper cost for the wall is $1,248

Quadrilateral ABCD is inscribed in circle O.
What is m∠B ?
Enter your answer in the box.
The measure of angle B is 125 degrees in the given quadrilateral inscribed in circle O.
In a quadrilateral inscribed in a circle, opposite angles are supplementary.
Therefore, we can set up the equation:
∠A + ∠C = 180 degrees
Substituting the given values:
(2x-7) + (x+4) = 180
Combining like terms:
3x - 3 = 180
Adding 3 to both sides:
3x = 183
Dividing both sides by 3:
x = 61
Now we can find ∠B:
∠B = 2x + 3
∠B = 2(61) + 3
∠B = 122 + 3
∠B = 125
Therefore, m∠B is equal to 125 degrees.
