The amount of fencing needed to surround the perimeter of the picnic area of the park is 107 yards. Hence, the second option is the right choice.
In the question, we are informed that the triangle KLM, represents a section of a park set aside for picnic tables. We are also informed that the picnic area will take up approximately 400 square yards of the park.
We are asked for the amount of fencing needed to surround the perimeter of the picnic area of the park.
We know the area of a triangle can be found using the trigonometric area formula, Area = (1/2)ab sin C.
Using this in the given triangle KLM, we get:
Area = (1/2)(KL)(KM)(sin K),
or, 400 = (1/2)(KL)(45)(sin 25°),
or, KL = (400*2)/(45*sin 25°) = 800/(45*0.42262) = 800/19.017822 = 42.0658 ≈ 42 yd.
Thus, we get KL = 42 yards.
Now, the perimeter of the picnic area = the perimeter of the triangle KLM = KL + LM + MK = 42 + 20 + 45 yards = 107 yards.
Thus, the amount of fencing needed to surround the perimeter of the picnic area of the park is 107 yards. Hence, the second option is the right choice.

Give the values of b, h, and k for the function
The value of b = 5 , h = -4 and k = -1 for the function f(x) = [tex]log_{5}[/tex](x - 4) - 1
What is a function ?
An expression, rule, or law in mathematics that specifies the relationship between an independent variable and a dependent variable (the dependent variable).
A relationship between a group of inputs and one output each is referred to as a function. In plain English, a function is an association between inputs in which each input is connected to precisely one output. A domain, codomain, or range exists for every function.
An input is connected to an output by a function. It resembles a device with an input and an output. In addition, the output is somehow connected to the input. The standard way to write a function is f(x) "f(x) =... "
Translated of logarithmic function:
f(x) = [tex]log_{b}[/tex] (x + h) + k
where b is base, h - horizontal shift, k - vertical shift

(For all numbers, put in the change. If there is no change, make sure you put .00. For example, if the amount was 27, make sure you put 27.00.
If there is no number in the pennies place, make sure you put a 0. For example, if your amount was 5.4, make sure you put 5.40)
The Subtotal for 25 flash drives is $250.00. You can save $62.50. The new Subtotal becomes $187.50. Sales tax of 4% will equal $7.50. The Total for the 25 flash drives will be $187.50 + $7.50 which gives $195.00
To find the solution, we must solve for the questions individually;
The Subtotal is 25 x $10 = $250.00
You save = 25% of $250
which is 25/100 x 250 = $62.50
The new Subtotal = $187.50
Sales tax of 4% = 4% of $187.50
which gives 4/100 x 187.5 = $7.50
The Total for the 25 flash drives will be $187.50 + $7.50 = $195.00

The interest rate for Rebeka's account is 5%.
What is the meaning of interest rate?
The amount that the lender charges the borrower over and beyond the principal amount is referred to as the interest rate. A person who deposits money in a bank or other financial institution also earns additional income in terms of the recipient, known as interest, taking into account the time value of money.
Given that, Rebeka deposits $1500. She earn $131.25 as interest after 21 months.
The formula of simple interest is
I = PRT
I = interest
P = Principal
R = Rate of interest
T = time
In the given question,
P = $1500
I = $131.25
T = 21 months = 21/12 years.
Putting P = $1500, I = $131.25, T = 21/12 years in I = PRT:
131.25 = 1500 × R × (21/12)
Divide both sides by 1500 × (21/12):
R = 131.25 /[1500 × (21/12)]
R = [131.25 × 12] /[1500 × 21]

The price that is the Second standard above the mean, if the mean is $10000 and the standard deviation is $500 is $18000.
What is mean?The central tendency along the median and mode of a probability distribution is measured by the mean. It is also known as "expected value."
Given:
The mean, m = $17000,
The standard deviation, σ = $500
Calculate the second standard deviation as shown below,
Second standard deviation = mean + 2 × standard deviation
Second standard deviation = 17000 + 2 × 500
Second standard deviation = 17000 + 1000
Second standard deviation = $18000

Find the coordinates of N so that the ratio of MN to NP is 5 to 4.
The coordinate of the point N that divides the line segment MP will be (9, -5).
What is the section of the line?Let A (x₁, y₁) and B (x₂, y₂) be a line segment. Then the point P (x, y) divides the line segment in the ratio of m:n. Then we have
x = (mx₂ + nx₁) / (m + n)
y = (my₂ + ny₁) / (m + n)

Since the coefficients of the expression of two logs are not the same, we need to adjust the exponents in order to combine them into one logarithm. Since the first logarithm has a coefficient of 1/4, we multiply the exponent of the second logarithm by 4/7 to get 4/7*4 which is equal to 4. We then add 4 to the exponent of the first logarithm to get 11. This gives us a combined logarithm of logbx^4y^11/28.

Graph the points (0.5,4.5) and (-0.5,-4.5)
Answer:
Step-by-step explanation:
To graph the points (0.5, 4.5) and (-0.5, -4.5) on a coordinate plane, you can use a ruler or a graph paper to plot the points.
To plot the point (0.5, 4.5), start by drawing the horizontal and vertical axes of the coordinate plane. The horizontal axis, or the x-axis, is the line that runs horizontally across the plane, and the vertical axis, or the y-axis, is the line that runs vertically. The intersection of the two axes is called the origin.
Next, locate the point (0.5, 4.5) on the coordinate plane. To do this, find the point that is 0.5 units to the right of the y-axis and 4.5 units above the x-axis. This point is the point (0.5, 4.5).
To plot the point (-0.5, -4.5), locate the point that is 0.5 units to the left of the y-axis and 4.5 units below the x-axis. This point is the point (-0.5, -4.5).
The resulting graph should look like this:

What is the value of x that would make like a parallel to line b
Answer:
x = 16
Step-by-step explanation:
If the lines were parallel then (12x - 50) and (8x + 14) are alternate angles and are congruent , then
12x - 50 = 8x + 14 ( subtract 8x from both sides )
4x - 50 = 14 ( add 50 to both sides )
4x = 64 ( divide both sides by 4 )
x = 16
For a and b to be parallel then x = 16
Show that the function f(x) = x + 5x + 1 has exactly one zero in the interval (-1,0). Which theorem can be used to determine whether a function f(x) has any zeros in a given interval?
The function f(x) = x + 5x + 1 has exactly one zero in the interval (-1, 0). To prove this, we can use the Intermediate Value Theorem.
This theorem states that if a function f(x) is continuous on an interval [a, b] and if its values at a and b have opposite signs, then there exists at least one root (zero) of the function in the interval (a, b). Therefore, since f(-1) = -6 and f(0) = 1, both of which have opposite signs, the Intermediate Value Theorem can be used to conclude that there exists at least one root of the function in the interval (-1, 0).
Furthermore, since the function is a quadratic function of the form f(x) = ax2 + bx + c, it is known that a quadratic equation can have at most two roots (zeros) (in a given interval). Therefore, since the Intermediate Value Theorem implies that the function f(x) has at least one zero in the interval (-1, 0), it follows that the function has exactly one zero in the interval (-1, 0).

interpretation in the context of the problem.
The linear function for D is defined as follows:
D(t) = -35t + 280.
The slope of 35 means that Nathan is traveling at a velocity of 35 miles/km per hour.
How to define the linear function?The linear function for this problem is defined in slope-intercept format, as follows:
y = mx + b.
The coefficients of the function are given as follows:
m is the slope, representing the rate of change of the output variable y relative to the input variable x.b is the y-intercept, representing the initial value of the output variable y.From the table, two points are given as follows:
(3, 175) and (5,105).
Given two points, the slope is calculated as the change in y divided by the change in x, hence:
m = (105 - 175)/(5 - 3) = -35.
This slope represents that Nathan is traveling at a velocity of 35 miles/km per hour.
Hence:
D(t) = -35t + b
When x = 3, y = 175, hence the intercept b is obtained as follows:
175 = -35(3) + b
b = 280.
Thus the function is of:
D(t) = -35t + 280.
