(2) 50°, 100°, 30°
(4) 70°, 70°, 60°
Answer:
Step-by-step explanation:
The sum of three angles in a triangle is equal to 180°.
(1) 40°, 90°, 60°
40 + 90 + 60 = 190. Therefore, it could not be the measures of the three angles if a triangle.
(3) 120°, 30°, 20°
120 + 30 + 20 = 170. Therefore, it could not be the measures of the three angles if a triangle.
(2) 50°, 100°, 30°
50 + 100 + 30 = 180. Therefore, it could be the measures of the three angles if a triangle.

Concert the polar equation of a conic section to a rectangular equation: r(1+3 sinθ) =4
This is the equation of a hyperbola, since it has a constant difference between the distances from any point on the curve to two fixed points (known as the foci). In this case, the foci are located at (-2, 0) and (2, 0).
To convert the given polar equation, r(1+3sinθ) = 4, to a rectangular equation, we can use the following equations:
x = rcos(θ)
y = rsin(θ)
Substituting r(1+3sinθ) = 4, we get:
x = r*cos(θ) = (4/(1+3sinθ))cos(θ)
y = rsin(θ) = (4/(1+3sinθ))*sin(θ)
Simplifying further, we can use the identity sin^2(θ) + cos^2(θ) = 1 to get:
x = 4cos(θ)/(1+3sinθ)
y = 4sin(θ)/(1+3sinθ)
Therefore, the rectangular equation of the conic section in terms of x and y is:
x = 4cos(θ)/(1+3sinθ)
y = 4sin(θ)/(1+3sinθ).

years. If the income is reinvested in a business earning interest at the rate of 8% per
year, compounded continuously, find the Accumulated Total Value of this income
stream at the end of 6 years.
Which of the following is NOT a good method for solving the problem?
The correct option number that is NOT a good method for solving the problem is: Option C: 20.48.[c-0.08.6-c0] (45000. ((0.08)(6)=0.08. t)at 45000-(00:48) Il 6 -0.08- 1) at -562500- 20.48.[c-0.08.6-c0]
The problem requires finding the Accumulated Total Value of the income stream generated by Hank's Auto Wash over six years, assuming the income is reinvested at an interest rate of 8% per year, compounded continuously. To solve the problem, we need to use the formula for continuous compounding:
A = P[tex]e^{(rt)[/tex]
Where A is the accumulated total value, P is the initial principal (in this case, the annual revenue of $45,000), e is the mathematical constant e (approximately 2.71828), r is the interest rate (0.08), and t is the time period (6 years).
Plugging in the values, we get:
A = 45000[tex]e^{(0.086)[/tex]
A = 45000[tex]e^{0.48[/tex]
A = 450001.6186
A = $72,838.50
Therefore, the accumulated total value of the income stream at the end of 6 years is $72,838.50.

Answer:
[tex]g(x) = f(x) - 4[/tex]
Step-by-step explanation:
We have been given a graph for f(x) and a table for g(x) and we have to find the transformation to map f(x) to g(x)
Let's find the function values for f(x) and g(x) at specific (easily distinguishable) x values for both
x f(x) from graph g(x) from table
0 4 0
1 3 -1
2 4 0
The function values for f(x) for x = -1 and x = 3 are a bit difficult to read since they do not cross at a grid intersection
From the above table we see that for a specific x, g(x) value is 4 less than the f(x) value
Therefore the transformation is
g(x) = f(x) - 4
Therefore g(x) is shifted downward by 4 points
I have plotted both f(x) and g(x) using the transformation; You can see the points fit
[tex]-------------------------------[/tex]
Ignore this part if you wish
The equation for f(x) is
f(x) = (x - 1)² + 3 in vertex form
or
f(x) = x² − 2x + 4 in polynomial form
g(x) will then be
x² - 2x + 4 - 4 = x² -2x

Use the sum from Part (c) and show your work.
The standard deviation of the data set is 11.75.
To calculate the standard deviation of the data set, we first need to find the variance, which is the average of the sum of squares of the differences between each data value and the mean. We already calculated the sum of squares of the differences in Part (c), which is 828.
The formula for variance is:
variance = sum of squares of differences / number of data values
Since we have six data values, the variance is:
variance = 828 / 6
variance = 138
Now we can calculate the standard deviation, which is the square root of the variance:
standard deviation = sqrt(variance)
standard deviation = sqrt(138)
standard deviation = 11.75 (rounded to two decimal places)
Therefore, the standard deviation of the data set is 11.75.

Determine the measures of the marked angles in the figure shown.
The measures of the marked angles in the figure are:
x = 0.8°
6x + 8° = 12.8°
x + 12° = 12.8°
How do we calculate?We have that:
x + 12° and 6x + 8°.
We equate the expression: 6x + 8° = x + 12°
We then solve for x:
6x - x = 12° - 8°
5x = 4°
We then divide both sides by 5:
x = 4° / 5
x = 0.8°
We get the measure of the marked angle for
6x + 8°:
6(0.8°) + 8° = 4.8° + 8° = 12.8°
We also get the measure of the marked angle as:

How many edges on a cylinder?
A cylinder has two types of edges: the curved edges and the top and bottom edges.
A cylinder is a three-dimensional geometric shape that consists of two circular bases and a curved surface connecting the bases. The circular bases have a certain number of edges, depending on the number of sides each base has.
Since a circle has no straight edges, the circular bases of a cylinder do not contribute any edges.
The curved surface of a cylinder has no straight edges either, as it consists of a smooth, continuous surface.
Therefore, the curved surface does not contribute any edges to the cylinder.
The only remaining edges are the top and bottom edges of the cylinder. Each base of the cylinder has a single edge that runs along the circumference of the circular base.
Hence, the cylinder has two edges from its top and bottom bases.

After 1 day, you notice that your 2 magical beans have turned into 4 magical beans. After 2 days you look and there are 8 magical beans. On the third day you notice there are now 16 beans. Since you are a brilliant mathematician, you decide to estimate how many beans you will have after 15 days.

C

D

(c)
Part C
Estimate how many days you would need to have doubled your beans for the trade to make sense.
Part A: After 15 days will have 32,768 magical beans.
Part B: As the value of the magical beans is less than the value of the car the trade does not make sense at least not from a financial perspective. B NO.
Part C: We would need at least 17 days for the number of magical beans to exceed the value of the car. C MAYBE?.
Based on the given information can observe that the number of beans doubles every day.
So, after 15 days will have 2¹⁵ = 32,768 magical beans.
The value of the 32,768 magical beans would be:
32,768 beans × $0.50/bean
= $16,384
Part C:
Let us assume that after 'n' days, the number of beans would be equal to or greater than the value of the car.
Value of the car in terms of magical beans = $65,000/$0.5 per bean
= 130,000 beans
Now, we can set up an equation based on the doubling of beans:
2ⁿ >= 130,000
Taking the logarithm base 2 on both sides, we get:
n × log2(2) >= log2(130,000)
n >= log2(130,000)
n >= 16.98
We would need at least 17 days for the number of magical beans to exceed the value of the car.

By substituting the values of A, C, and D the equation modelling the function is;g(x) = 3·sin(x - π/2) - 4
Step-by-step explanation:
From the given information, we have;The vertical stretch of the sine function = 3 × The parent function∴ A = 3Given that the horizontal shift left = π/2 units, (from an online source with similar question)The vertical shift down = 4 unitsThe given function, g is g(x) = A·sin(x + C) + DWhere;A = The amplitude = The maximum displacement from the rest or equilibrium position = 3C = The horizontal shift = -π/2 (The negative sign is for the shifting to the left)D = The vertical shift = -4 (The negative sign is for a shift in the downward direction)Therefore, the equation modelling the function is;g(x) = 3·sin(x - π/2) - 4
Use the laws of exponents to write an equivalent expression.
Using the laws of exponents, the equivalent expression would be 1 / 64.
How to find the equivalent expression?To find the equivalent expression of ( 4 / 7 ) ⁻ ³ . 7 ⁻³, we can use the law of exponents.
Using this law, we get:
( 4 / 7 ) ⁻ ³ = ( 1 / ( 4 / 7 )) ³
( 1 / ( 4 / 7 )) ³ = ( 7 / 4 ) ³
( 7 / 4) ³ x 7 ⁻³
( 7 / 4) ³ x ( 1 /7 ³ )
(( 7 ³ ) /( 4 ³ ) ) x ( 1/ 7 ³ )
( ( 7 ³ ) / ( 4 ³ ) ) x ( 1 / 7 ³ ) = 1 / (4 ³ )
1 / (4 ³ ) = 1 / 64
In conclusion, the equivalent expression is 1 / 64.
