What is the triangle?A triangle is a three-sided polygon with three angles. The angles of the triangle add up to 180 degrees.
In a triangle, if the angle is small then the opposite side will be short, and if the angle increases then the side also increases.
The sides of the triangle are in ascending order, then we have
WY < YZ < WX < XY < XZ
Then the sequence of the angles is given as,
∠WXY < ∠YXZ < ∠WYX < ∠XZY < ∠XYZ
The sequence of the angles from least to biggest is ∠WXY < ∠YXZ < ∠WYX < ∠XZY < ∠XYZ.

Find the values of x and y. State which theorem(s) you used.
The required simplified value of x and y is 32 and 84 respectively.
Given that,
To find the values of x and y. State which theorem(s) you used.
The process in mathematics to operate and interpret the function to make the function or expression simple or more understandable is called simplifying and the process is called simplification.
Vertical opposite angles
3x = 5x - 64
2x = 64
x = 32
Now,
5x - 64 = 5*32 - 64
= 160 - 64
= 96°
Now complementary angle y
y = 180 - 96°
y = 84°
Thus, the required simplified value of x and y is 32 and 84 respectively.

Find the center and the radius of each circle. x²+y²-4 y-16=0
The center and radius of the circle given by the equation x^2 + y^2 - 4y - 16 = 0 is (0 , 2) and 2√5, respectively.
The standard form of the equation of circle is given by
(x - h)^2 + (y - k)^2 = r^2
where (h , k) is the location of the center and r is the radius of the circle.
On the other hand, the general form of the equation of circle is given by
x^2 + y^2 + Dx + Ey + F = 0
where D = -2h, E = -2k, and F = h^2 + k^2 -r^2.
If the equation of the circle in general form is x^2 + y^2 - 4y - 16 = 0, then the coefficients are:
D = 0
E = -4
F = -16
If D = -2h and D = 0, then
0 = -2h
h = 0
If E = -2k and E = -4, then
-4 = -2k
k = 2
If F = h^2 + k^2 -r^2 and F = -16, then
-16 = 0^2 + 2^2 - r^2
r^2 = 0 + 4 + 16
r^2 = 20
r = 2√5

Connor has a biased dice. The
probability of it landing on a
three is 0.8. Connor is going to
throw the dice 120 times.
Work out an estimate for the
number of times the dice will
land on a three.
Step-by-step explanation:
120×0.8
120/10)×8
=12×8
=96
The estimated number of times the dice will land on a three in 120 throws is 96 times.
We have,
To estimate the number of times the biased dice will land on a three, we can use the probability of getting a three in a single throw and multiply it by the total number of throws.
Probability of landing on a three in a single throw = 0.8
Total number of throws = 120
Estimated number of times the dice will land on a three
= Probability of landing on a three × Total number of throws
Estimated number of times = 0.8 × 120
Estimated number of times = 96
So, based on the biased dice with a probability of 0.8 for landing on a three, the estimated number of times the dice will land on a three in 120 throws is 96 times.
Thus,
The estimated number of times the dice will land on a three in 120 throws is 96 times.

FITNESS A fitness instructor is starting a new aerobics class using fitness hoops. She, wants to confirm that all of the hoops are the same size. What measure(s) can she use to prove that all of the hoops are congruent? Explain your reasoning.
The instructor can use Mathematical coincidence to prove that all of the hoops are congruent.
What do we mean by Mathematical coincidence?The term "coincide" refers to something happening at the same time. In mathematics, coincident lines are lines that lie on top of each other so that when we look at them, they appear to be a single line rather than double or multiple lines. Two lines as well as shapes that are exactly on top of one another.For instance, these two lines are coincidental, but they appear to be one line because they are on top of each other.So, the fitness instructor should use Mathematical coincidence and should keep the hoops on one another to check the congruency.
Therefore, the instructor can use Mathematical coincidence to prove that all of the hoops are congruent.

Which expression is equivalent to (3x^−4y^5) ^−2?
A: -9^8y^10
B: x^8/ 9y^10
C: -9x^8/ y^10
D: 1/ 9x^8y^10
(x's are variables not multiplication) (dashes resemble fractions) (^ resembles powers)
The equivalent expression to the given one is x^8/(9*y^10)
So the correct option is B.
Which expression is equivalent to (3x^−4y^5) ^−2?Here we just need to operate with the exponent properties that we know and love.
Remember that:
(a^n)^m = a^(n*m)
Then if we apply that to our case we will get:
(3x^−4y^5) ^−2 = (3^(-2)*x^(-4*-2)*y^(5*-2))
= (3^(-2)*x^8*y^(-10)
Now remember that negative exponents just "move" the number to the denominator position, this means that:
3^-2 = 1/3^2 = 1/9
Then we can rewrite our expression as:
(3^(-2)*x^8*y^(-10) = x^8/(9*y^10)
That is the equivalent expression to the given one.
The correct option is B.

For the geometric sequence 3,12,48,192, . . . . . , find the indicated term.17 th term
The 17th term of the given geometric sequence, 3, 12, 48, 192, . . . , is 1.288490189 x 10^10.
A geometric sequence refers to a sequence of numbers, which the next term is obtained by multiplying the previous term with a constant, called a ratio.
a(n) = a r^(n-1)
Where:
a(n) = nth term
r = ratio
Given the geometric sequence 3, 12, 48, 192, . . .
Find the ratio,
r = a(n)/a(n-1)
r = a(2)/a(1)
r = 12/3
r = 4
Notice that the ratio between two succeeding terms is always 4.
Use the formula to find the 17th term of the geometric sequence.
a(n) = a r^(n-1)
a(17) = 3[4^(17-1)]

As given in the question,
Let the possible outcomes of the given event is represented by S.
Formula used :
Probability of an event
= (Favorable outcomes) /(Total Number of possible outcomes)
When a dice is rolled, all possible outcomes are 1, 2, 3, 4, 5, 6.
Sample space, S =(1, 2, 3, 4, 5, 6)
Favorable outcomes = Only 1 is smaller than 2, remaining number is greater than 2

What is termed as logarithmic functions?A logarithmic term is a number expressed in logarithmic form. Some other name for it is a log term.
A number could also be the sum of two or more numbers. As a result, a term can be the product of two or even more quantities, at least one of which should be in logarithmic form. These same terms are recognised as log terms in such cases.A quantity can also be described as the variation between two quantities. However, if a term contains a quotient of quantities, or if at least one of the amounts can also be conveyed in log form, the term is referred to as a log term.Consider some formulas used in log.
Quotient Rule: ㏒(A/B) = ㏒A - ㏒BProduct Rule : ㏒A + ㏒B = ㏒(AB)Power Rule: n㏒A = ㏒AⁿBase Rule = ㏒ₐb = ㏒ₓb/㏒ₓaExponent Rule = e∧lnx = xNow, as per the given question,
The function is written as;
P = 42e∧(-0.005t).
The value of the power P is mentioned in the question; (P = 35 watt).
Thus, substitute the value of the P in teh equation;
35 = 42e∧(-0.005t).
Now, divide both sides by 42.
0.8333 = e∧(-0.005t)
Taking natural log on both side;
㏒0.8333 = ㏒e∧(-0.005t)
㏒0.8333 = -0.005t
Solve the value of the log by using calculator,
-0.182 = -0.005t
t = 36.5
Therefore, the the life for which the battery will run is 36.5 years.

What exactly do we mean by a triangle's congruency?Two triangles are said to be congruent if all three corresponding sides are equal and all three corresponding angles are equal in measure.These triangles can be moved, rotated, flipped, and turned to appear identical.If they are repositioned, they will coincide.If two triangles satisfy the five congruence conditions, they are congruent.They are side-side-side (SSS), side-angle-side (SAS), angle-side-angle (ASA), angle-angle-side (AAS), and right angle-hypotenuse-side (RHS).So,
Given:
LM ≅ NMMO bisects ∠L M NTo prove congruency:
MO = MO (Common line)LM = NM = Given∠LM0 = ∠NMO = equal angles (As MO bisects ∠LMN)Therefore, ΔM LO ≅ ΔMNO under SSA congruency.

Given equation,
→ C = 29.95 + 0.035x
Then the call duration will be,
→ C = 29.95 + 0.035x
→ 43.53 = 29.95 + 0.035x
