What is domain?
The range of values that we are permitted to enter into our function is known as the domain of a function. The x values for a function like f make up this set (x). A function's range is the collection of values it may take as input. After we enter an x value, the function outputs this sequence of values.
The domain of a function is the set of input or argument values for which the function is real and defined
The function has no undefined points nor domain constraints. Therefore, the domain is [tex]$$-\infty < x < \infty$$[/tex].

3. What is the relationship between angles M and R?
The relationship between angles R and R is: B. m∠M > m∠R.
What is the Relationship of the Angles of Two Triangles?The size of the angles in a triangle is related to the length of the side they are opposite to. That is, the largest angle is opposite the longest side and vice versa. This is the basis of the relationship of the corresponding angles of two triangles with two equal sides, and a third unequal sides.
In the image given, we see that two corresponding sides of the two triangles are equal to each other, MN = RS, and MP = RT.
Since the side that is opposite to the third angle in triangle MNP is greater than the side that is opposite to the third angle in triangle RST, NP > ST, therefore, it follows that the size of angle M that is opposite to side NP would be greater than the size of angle R that is opposite to side ST.
In conclusion, we can state that the relationship is, B. m∠M > m∠R.

A theater group made appearances in two cities. The hotel charge before tax in the second city was $1500 lower than in the first. The tax in the first city was 9.5% , and the tax in the second city was 10% . The total hotel tax paid for the two cities was 971.25
. How much was the hotel charge in each city before tax?
Answer: Let x = the charge in 1st city before taxes
Let y = the charge in 2nd city before taxes
Set up equation before taxes.
y = x - 1500 eq1
Set up equation for total tax paid.
0.065x + 0.06y = 378.75 eq2
Substitute eq1 into eq2.
0.065x + 0.06(x - 1500) = 378.75
0.065x + 0.06x - 90 = 378.75
0.125x - 90 = 378.75
0.125x = 468.75
x = 3750
Substitute this value of x into eq1.

Find the measure of ∠ 1
a 92°
b 58°
c 122°
d 30°
The value of ∠1 is 58 degree. So the option be is correct.
In the given question we have to find the measure of angle 1.
The given options are:
(a) 92 degree
(b) 58 degree
(c) 122 degree
(d) 30 degree
As we know that the triangle have three sides and three angles. The sum of all angles is 180 degree.
From the given question we can see that the
Angle two ∠2 = 92 degree
Angle three ∠3 = 30 degree
So ∠1+∠2+∠3 = 180
Now putting the value
∠1+92+30 = 180
∠1+122 = 180
Subtract 122 on both side, we get
∠1 = 58
Hence, the value of ∠1 is 58 degree. So the option be is correct.

What range of temperature will a plane be exposed to if it takes off and reaches a maximum height of 6 km?
Write answer in interval notation. The range is
The formula for the function T(x) is T(x) = 18 - x/100
The temperature at a height of 6 km is 17.94°CThe range in interval notation is (-oo, oo)The formula for the functionFrom the question, we have the following parameters that can be used in our computation:
Rate = 1°C for every 100 m rise
Ground temperature = 18°C
This means that the function can be represented as
T = Ground temperature (G) - Rate * Height (x)
Where
T is temperatureG is the temperature at ground level.x is the height above ground level measured in metersSo, we have
T(x) = 18 - x/100
The temperature at a height of 6 kmThis means that
x = 6
Recall that
T(x) = 18 - x/100
So, we have
T(6) = 18 - 6/100
Evaluate
T(6) = 17.94
The range in interval notationIn (a), we have
T(x) = 18 - x/100
This is a linear function

7.5 cups of tomato paste can be made from 25 pounds and 14 cups can make 46.67 pounds.
What is unitary method?The unitary approach is a strategy for problem-solving that involves first determining the value of a single unit, then multiplying that value to determine the required value.
Given, it takes 10 pounds to make 3 cups of tomato paste.
Thus, with 1 pound, number of cups can be made is equal to (3/10) cups
Thus, using 25 pounds, number of cups can be made is equal to
(3/10)*25

Find the unknown value in the
proportion (2x+1)=2 (x+2] :5
Answer:
To find the unknown value in the proportion (2x + 1) / 2 = (x + 2) / 5, we can cross-multiply the terms on the left-hand side and the right-hand side to eliminate the fractions. This gives us the equation 2(2x + 1) = 5(x + 2), which simplifies to 4x + 2 = 5x + 10. Subtracting 4x from both sides of the equation, we get 2 = x + 10, which can be rewritten as x = -8. Therefore, the unknown value in the proportion is x = -8.

account c has a 3.9 % apr compounded daily ( 365 times per year). determine the account value's growth factor and percent change per compounding period.
Answer:
Step-by-step explanation:
The compound interest period rate is P = Po(1±r/t)n(t)
Here,
r = .039
t = 365
The daily rate in this situation is = .039/365
The factor for 1 compounding period for a year = (1+(.039/365))365 = 1.039768317
The growth factor is = 3.9768317%
The accounts value's growth factor is 1.0000107227, and the percent change per compounding period is 0.107227%.
What is the growth factor?
The account value's growth factor is the factor by which the account value increases each compounding period. It is given by the formula:
[tex]$growth factor$ = (1 + APR /{$compounding frequency$}) ^ {($compounding frequency$ / $period$)}[/tex]
In this case, the APR is 3.9%, the compounding frequency is 365 times per year (daily), and the period is one year. Plugging these values into the formula, we get:
growth factor = (1 + 0.039 / 365) ^ (365 / 1) = 1.0000107227
The percent change per compounding period is the amount by which the account value increases each compounding period, expressed as a percentage. It is given by the formula:
percent change = (growth factor - 1) * 100
Plugging the value of the growth factor that we calculated earlier into this formula, we get:
percent change = (1.0000107227 - 1) * 100 = 0.107227%
Therefore, the account value's growth factor is 1.0000107227, and the percent change per compounding period is 0.107227%.
