In isosceles trapezoids, the diagonals are not perpendicular. They are congruent, the bases are parallel, and the non-parallel sides are congruent.
Explanation:An isosceles trapezoid is a type of quadrilateral that has a pair of parallel sides, known as the bases, and the other two sides, not parallel, are of equal length. The statement 'The diagonals are perpendicular' is NOT true for isosceles trapezoids. In isosceles trapezoids, the diagonals are congruent and not perpendicular. Just to put in context, the perpendicular diagonals are a characteristic of rhombuses and not of isosceles trapezoids.

The value of x in the triangle using the principle of Pythagoras is 2879.4 meters
Given the right angle triangle :
The angle of elevation = 10°Opposite side = 500 mx = hypotenusRecall :
SOHCAHTOAUsing the relation :
Sin θ = opposite / hypotenus
Sin 10° = 500 / x
Cross multiply :
x(sin 10°) = 500
0.1736481x = 500
x = 500 / 0.1736481
x = 2879.39 meters
Therefore, the value of x in the triangle is 2879.4 meters.

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

AD←→ is tangent to circle M at point D. The measure of ∠DMQ is 50º.
What is the measure of ∠DQM?
Answer:
Hello! I just completed the quiz :))
Step-by-step explanation:
This is for more confirmation (´｡• ᵕ •｡`) ♡ glad I could help!
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.

Lyle deposited a check for $75.26. He’ll use the check register to record his transaction. What will be his new balance?
$896.44
ExplanationRemember that to get the current balance, you subtract all the debits from balance and add all the deposits to it.
We know from our table that the first transaction is medical bill, which is debit, so we are going to subtract the medical bill from the balance to find the balance at that point in time.
Balance = $862.74 - $41.56 = $821.18
We also know that the second transaction is a check deposit for $75.26, so to find the current balance, we just need to add $75.26 to our previous balance.
Current balance = $821.18 + $75.26 = $896.44

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.

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 measure of angle P?
Enter your answer as a decimal in the box. Round only your final answer to the nearest hundredth.
Answer:
The measure of angle P is 61.93°
Step-by-step explanation:
We are given a right triangle with measures 8 cm, 15 cm and 17 cm.
For angle P, we see that,
Perpendicular = 15 cm
Hypotenuse = 17 cm
Using the trigonometric forms of the angles, we have,
[tex]\sin P=\frac{Perpendicular}{Hypotenuse}[/tex]
i.e. [tex]\sin P=\frac{15}{17}[/tex]
i.e. [tex]\sin P=0.88235[/tex]
i.e. [tex]P=\arcsin 0.88235[/tex]
i.e. P = 61.93°
Hence, the measure of angle P is 61.93°.
