The figure is represented by the inequality y ≥ 5 · x² - 40 · x - 45. (Correct choice: C)
What inequality represents the figure
In accordance with the figure, we have an inequation of the form y ≥ f(x). Now we proceed to find the quadratic equation of the parabola:
f(x) = a · (x + 1) · (x - 9)
- 125 = a · (4 + 1) · (4 - 9)
- 125 = a · 5 · (- 5)
- 125 = - 25 · a
a = - 5
f(x) = 5 · (x + 1) · (x - 9)
f(x) = 5 · (x² - 8 · x - 9)
f(x) = 5 · x² - 40 · x - 45
The figure is represented by the inequality y ≥ 5 · x² - 40 · x - 45. (Correct choice: C)

Morgan cycled from Town A to Town B at an average speed of 15 km/h. She reached Town B at 6 P.M. If she increased her average speed to 20 km/h, she would arrive at 5 P.M. At what time would she arrive at Town B if she cycled at an average speed of 25 km/h?
Answer: Morgan will arrive at Town B at 5pm - 36 minutes = 4:24pm if she cycled at an average speed of 25km/h.
Step-by-step explanation: To solve this problem, we can use the formula: distance = speed x time.
We know that at 15km/h, Morgan reaches Town B at 6pm, and at 20km/h, she reaches Town B at 5pm.
We can use this information to find the distance between Town A and Town B and the time it takes to travel this distance at 25 km/h.
First, let's find the distance between Town A and Town B:
distance = speed x time
distance = 15 km/h x time
time = distance / 15 km/h
time = (distance / 15) hours
Since we know that when Morgan travel at 15km/h to reach town B at 6pm, we can use the time to calculate the distance:
time = 6pm - 5pm = 1hour
distance = 15 km/h x 1 hour = 15 km
Next, we can use this distance and the new speed 25km/h to calculate the arrival time:
time = distance / speed
time = 15 km / 25 km/h = 0.6 hours = 36 minutes
So, she will arrive at Town B at 5pm - 36 minutes = 4:24pm if she cycled at an average speed of 25km/h.
Please note that this calculation is assuming that the distance between Town A and Town B is a constant, and assuming that the time of arrival at 15km/h and 20km/h are accurate.

The area issue with the suggested remedy is that the playing field is 118 feet by 56 yards in size.
Define the area.To determine area, multiply length by width. L times B is the formula for calculating area. Area or Radius = r2(=3.14) These methods can also be used to calculate the areas of different quadrilaterals, which are polygonal shapes with four sides and an aspect lower than 90 degrees. Application. Since its inception, area has been the foundation of geometry.
Here,
Our calculation of w = 56 reveals that the parallelogram is 56 yards long.
We can simplify the calculation by altering w to 56 in order to obtain the length of the rectangle but since width is the same as 2w + 6 already.
The rectangle is depicted as having a length of 118 yards.
Accordingly, the playing field measures 118 yards by 56 yards.
Therefore, the size of the game field—118 yards x 56 yards—is the solution to the current problem.

1. Is it possible for the sequence t(n) = 5·2ⁿ to have a term with the value of 200? If so, which term is it? If not, justify why not.
2. Is it possible for the function f(x) = 5·2ˣ to have an output of 200? If so, what input gives this output? If not, justify why not.
Answer:
1) No,2) Yes, x ≈ 5.32-----------------------------
Part 1Given sequence:
t(n) = 5 · 2ⁿIf t(n) = 200, we can try to find the value of n:
5 · 2ⁿ = 2002ⁿ = 40There is no integer solution, since 32 < 40 < 64 or 2⁵ < 40 < 2⁶, the value of n should be between 5 and 6.
The sequence should include integer numbers, so there is no solution.
Part 2Given function:
f(x) = 5 · 2ˣSolve for x if f(x) is 200:
5 · 2ˣ = 2002ˣ = 40log 2ˣ = log 40x log 2 = log 40x = log 40 / log 2x = 5.32 (rounded)Answer:
1. No
[tex]\textsf{2.} \quad x=\dfrac{\ln 40}{\ln 2} \approx5.32\;(\sf 2\;d.p.)[/tex]
Step-by-step explanation:
Question 1Given sequence:
[tex]t(n)=5 \cdot 2^n[/tex]
To determine if the sequence has a term with a value of 200, substitute t(n)=200 into the equation and solve for n:
[tex]\implies 5 \cdot 2^n=200[/tex]
[tex]\implies 2^n=40[/tex]
[tex]\implies \ln 2^n=\ln 40[/tex]
[tex]\implies n\ln 2=\ln 40[/tex]
[tex]\implies n=\dfrac{\ln 40}{\ln 2}[/tex]
[tex]\implies n=5.3219280...[/tex]
In a sequence, n is a positive integer. Therefore, it is not possible for the sequence to have a term with the value of 200, as when t(n)=200, n is not a positive integer.
Question 2Given function:
[tex]f(x)=5 \cdot 2^x[/tex]
To determine if the function has an output of 200, substitute f(x)=200 into the function and solve for x:
[tex]\implies 5 \cdot 2^x=200[/tex]
[tex]\implies 2^x=40[/tex]
[tex]\implies \ln 2^x=\ln 40[/tex]
[tex]\implies x=\dfrac{\ln 40}{\ln 2}[/tex]
[tex]\implies x=5.3219280...[/tex]
Therefore, it is possible for the function to have an output of 200 when:
[tex]x=\dfrac{\ln 40}{\ln 2}[/tex]
Sophia is buying a car and needs to take out a loan for $21, 000. The bank is offering
a monthly interest rate of 0.4%, for a 4 year loan. Using the formula below, determine
her monthly payment, to the nearest dollar.
On solving the provided question, we can say that Principal = 21,000, interest = 0.4% and time = 4 yrs => SI = $336
what is interest ?Simple interest is calculated by dividing the principal by the interest rate, the passage of time, and other elements. The formula used in marketing is simple return = principal + interest + hours. Using this approach, interest may be calculated most easily. The most common way to calculate interest is as a percentage of the principal balance. If he borrows $100 from a friend and agrees to pay it back with 5% interest, for instance, he will only pay his proportion of the 100% interest. $100 (0.05) = $5. You must pay interest when you borrow money and charge interest when you lend it. The majority of the time, interest is calculated as an annual percentage of the loan balance. This proportion is referred to as the loan's interest rate.
here,
Principal = 21,000
interest = 0.4%
time = 4 yrs
SI = Principal X Interest X time / 100
SI = 21000*0.4*4/100 = $336

triangle shows angles are 38°, (7x+1)°, (10x+9)°(outside of the triangle)
total angle of the triangle is 180°
then
38°+ (7x+1)°+ [180-(10x+9)°] = 180°
Simplifying
38 + (7x + 1) + [180 + -1(10x + 9)] = 180
Reorder the terms:
38 + (1 + 7x) + [180 + -1(10x + 9)] = 180
Remove parenthesis around (1 + 7x)
38 + 1 + 7x + [180 + -1(10x + 9)] = 180
Reorder the terms:
38 + 1 + 7x + [180 + -1(9 + 10x)] = 180
38 + 1 + 7x + [180 + (9 * -1 + 10x * -1)] = 180
38 + 1 + 7x + [180 + (-9 + -10x)] = 180
Combine like terms: 180 + -9 = 171
38 + 1 + 7x + [171 + -10x] = 180
Remove brackets around [171 + -10x]
38 + 1 + 7x + 171 + -10x = 180
Reorder the terms:
38 + 1 + 171 + 7x + -10x = 180
Combine like terms: 38 + 1 = 39
39 + 171 + 7x + -10x = 180
Combine like terms: 39 + 171 = 210
210 + 7x + -10x = 180
Combine like terms: 7x + -10x = -3x
210 + -3x = 180
Solving
210 + -3x = 180
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '-210' to each side of the equation.
210 + -210 + -3x = 180 + -210
Combine like terms: 210 + -210 = 0
0 + -3x = 180 + -210
-3x = 180 + -210
Combine like terms: 180 + -210 = -30

The factors of x² - 9 is +3 , -3.
What is factors ?
A factor is a number that completely divides another number. To put it another way, if adding two whole numbers results in a product, then the numbers we are adding are factors of the product because the product is divisible by them. Factors can be found using either division or multiplication.
A number or algebraic expression that evenly divides another number or expression—i.e., leaves no remainder—is referred to as a factor in mathematics.
The numbers that can divide a number exactly are called factors. There is therefore no residual after division. The numbers you multiply together to obtain another number are called factors. A factor is therefore another number's divisor.

An equation for a tangent to the graph of y = arcsin y/2 at the origin is
A. x-2y = 0 B. x-y = 0 C. x=0 D. y=0
Option A is the correct answer. An equation for a tangent to the graph of y=arcsiny/2 at the origin is x-2y = 0
The given equation is:
y=arcsiny/2---(1)
So to find the equation of the tangent line we required Fielding's first slope and we can find the slope by differentiating the equation of graft with respect to X.
The second thing we require is the point, also we have to find the slope accessible to zero
dy/dx=1/2/√1-x^/4
Also given that points meet at the origin means (0,0) the values of x, and y is 0 and substituted in the derivative equation, we get
y'(0)=1/2
y-0=1/2(x-0)
2y-0=x
x-2y=0
Therefore, An equation for a tangent to the graph of y = arcsin y/2 at the origin is x-2y=0

Which of the following decribes the domain and range of the function?
The domain is x < 2 or x ≥ 3 and the range y > - 3
What is the domain of a function?The domain of a function is the interval of valid inputs to the function.
What is the range of a function?The range of a function is the interval of valid outputs to the function.
How to find the domain and range for the function?Since we have the function
f(x) = -x/2 - 2 if x < 2 and f(x) = 2x - 4 if x ≥ 3.To find the domain of the function, we see that the values of x are between x < 2 or x ≥ 3.
So, the domain is x < 2 or x ≥ 3.
To find the range of the function, since
f(x) = -x/2 - 2 if x < 2 and f(x) = 2x - 4 if x ≥ 3.
Using the first function f(x) = -x/2 - 2 if x < 2 and substituing x = 2, we have that
f(2) = -2/2 - 2 = - 1 - 2 = -3
Since f(x) cannot be less than f(2), then
f(x) > - 3
So, y > - 3
Also, using the second function f(x) = 2x - 4 if x ≥ 3. and substituting x = 3 into the equation since this is the minimum value of x, then
f(3) = 2(3) - 4
= 6 - 4
= 2
Since this is the minimum value of f(3) = 2
So, y > 2
Since y > -3 and y > 2, combining both expressions, we have that
y > - 3
So, the range is y < -3
So, the domain is x < 2 or x ≥ 3 and the range y > - 3
