Answer:
12.75
Step-by-step explanation:
The computation of the geometric mean of sqrt 77 and sqrt 343 is given below:
As we know that
Geometric mean = \(\sqrt{ab}\)
where
a is the first number = \(\sqrt{77}\)
And, the b is the second number = \(\sqrt{343}\)
Now first we have to convert into a number
For a it, is = 8.78
And, for b, it is = 18.52
Now the geometric mean is
\(= \sqrt{8.78 \times 18.52}\)
= 12.75

what is the vertex of this quadratic function
Answer:
(-4,-9)
Step-by-step explanation:
vertex form: y=a(x-h)^2+k
hk=vertex of x and y
inside parentheses=horizontal (opposite signs)
that’s why it’s -4 instead of 4 for h (x) while -9 stays the same since it’s not inside the parentheses

Write the equation of a line perpendicular to the line: y=−5/2x+4 that goes through the point (-6, 0).
Step-by-step explanation:
the line given slope = x coefficient = -5/2
Perpendicular slopes must be opposite reciprocals of each other: m1 * m2 = –1
new slope = 2/5
line equation formula = y = mx+ b
m = slope
y= 2/5x + b
from the point given (-6,0)
x = -6
y = 0
0= -12/5 + b
b = +12/5
line equation =
\(y = \frac{2}{5} x + \frac{12}{5} \)

Enter
The value of the piecewise function for f(3) is 4
How to evaluate the piece-wise function for f(3)From the question, we have the following parameters that can be used in our computation:
f(x) = 2x if x < 1
f(x) = 1/2x + 5/2 if x >= 1
The function f(3) implies that we make use of the function
f(x) = 1/2x + 5/2
This is because it is valid for x >= 1
substitute the known values in the above equation, so, we have the following representation
f(3) = 1/2 * 3 + 5/2
Evaluate
f(3) = 4
Hence, the piecewise function for f(3) is 4

The given equation is rearranged to obtain 9x - 1 - (41 - 5x) = 0. By simplifying and solving the equation, we get x = 3.
To solve this equation, we first simplify it by subtracting what is to the right of the equal sign from both sides of the equation. This gives us 9x - 1 - 41 + 5x = 0, which simplifies to 14x - 42 = 0. We then pull out the like factor of 14 to obtain 14(x - 3) = 0.
Next, we use the zero product property to find the values of x that make the equation true. We know that 14 can never equal 0, so we focus on the expression inside the parentheses. Setting x - 3 equal to 0, we get x = 3.
Therefore, the solution to the given equation is x = 3.

find the circumference of circle with radius rcm
Step-by-step explanation:
By definition, pi is equal to c/d, where c is the circumference and d is the diameter.
This means that C = pi(d).
However, since diameter is twice the radius, if we let the radius be r cm, d=2r.
This gives that C=2pi(r).
can the method of undetermined coefficients with superposition be used to solve the de? a. no, since the coefficients of the de are not constant b. no, because the right side of the equation is not the correct type of function c. no, because the de is not linear d. yes
The option is (d) yes. The method of undetermined coefficients with superposition can be used to solve linear non-homogeneous differential equations with constant coefficients.
The method of undetermined coefficients with superposition can be used to solve linear differential equations with constant coefficients and non-homogeneous terms that are either polynomials, exponential functions, sines, cosines, or a combination of these functions. The method involves assuming a particular solution based on the form of the non-homogeneous term, and then adding the complementary solution to satisfy the homogeneous equation. The coefficients in the particular solution are determined by substituting it back into the original differential equation and solving for the unknowns. Superposition is then used to obtain the general solution by summing the particular and complementary solutions, each multiplied by their respective arbitrary constants.

A company is designing boxes to ship their product to stores. The design team decides that the width of the box should be five feet shorter than the length, and the height of the box should be three feet longer than the width. Due to shipping constraints, the length of the box can be no greater than six feet. The volume of the box, V(x), can be modeled by a polynomial function, where x is the length of the box. Which of the following correctly models the situation above and gives the correct domain?
Answer:
see below
Step-by-step explanation:
You can work this based only on the domain. You don't need to figure the volume, though you can if you want to check the answer further.
x represents the length of the box, which has a restriction that it can be no greater than 6 ft. This tells you x ≤ 6. However, the width is 5 ft shorter than the width, so its value is x-5. But we know the width must be greater than zero:
0 < x -5
5 < x
So, the constraints on the domain of x are ...
5 < x ≤ 6 . . . . . . only matches the last choice, (5, 6]
___
Checking the volume
The height is 3 more than the width, so the volume is ...
V = LWH = (x)(x -5)(x -5 +3) = x(x -5)(x -2) = x(x^2 -7x +10)
V = x^3 -7x^2 +10x

. assuming that the population data is normally distributed, what is the value hat you expect 67% of the data in the population to be smaller than?
Assuming that the population data is normally distributed, the value that you expect 67% of the data in the population to be smaller than is the first quartile (Q1).
Q1 is the value that divides the lower 25% of data from the higher 75%. It is also known as the 25th percentile. It is denoted by Q1.The normal distribution is symmetric, meaning that the area under the curve is equally distributed between the right and left of the mean. The 67% of the population data is located between the mean and the first quartile (Q1) since it is given that 67% of the data is smaller than the expected value.Therefore, the expected value that 67% of the data in the population to be smaller than is the first quartile (Q1).

A student plans to enroll at the university and plans to continue there until earning a PhD degree (a total time of 9 years). If the tuition for the first 4 years will be $7,200 per year and it increases by 5% per year for the next 5 years, what is the present worth of the tuition cost at an interest rate of 8% per year?
The present worth of the tuition cost for a student planning to enroll at the university for 9 years, with the first 4 years costing $7,200 per year and a 5% annual increase for the next 5 years, can be calculated at an interest rate of 8% per year. The present worth is $23,455.297.
To calculate the present worth of the tuition cost, we need to consider the time value of money, which accounts for the fact that money in the future is worth less than money in the present. We can use the concept of present value to determine the worth of future cash flows in today's dollars.
For the first 4 years, the tuition cost is constant at $7,200 per year. To find the present value of these cash flows, we can use the formula for the present value of a fixed cash flow series. Applying this formula, we find that the present value of the first 4 years' tuition cost is
\(7,200 + 7,200/(1+0.08) + 7,200/(1+0.08)^2 + 7,200/(1+0.08)^3.\)
For the next 5 years, the tuition cost increases by 5% per year. We can use the concept of future value to calculate the value of these cash flows in the last year of the 9-year period. Applying the formula for future value, we find that the tuition cost in the last year is \($7,200*(1+0.05)^5.\)
Finally, we can sum up the present value of the first 4 years' tuition cost and the future value of the tuition cost in the last year to obtain the total present worth of the tuition cost for the 9-year period.

If a figure is a square, its diagonals divide it into isosceles triangles.
p: A figure is a square.
q: A figure's diagonals divide into isosceles triangles.
Which represents the converse of this statement? Is the converse true?
The converse of the statement "If a figure is a square, its diagonals divide it into isosceles triangles" would be:
"If a figure's diagonals divide it into isosceles triangles, then the figure is a square."
The converse statement is not necessarily true. While it is true that in a square, the diagonals divide it into isosceles triangles, the converse does not hold. There are other shapes, such as rectangles and rhombuses, whose diagonals also divide them into isosceles triangles, but they are not squares. Therefore, the converse of the statement is not always true.
Therefore, the converse of the given statement is not true. The existence of diagonals dividing a figure into isosceles triangles does not guarantee that the figure is a square. It is possible for other shapes to exhibit this property as well.
In conclusion, the converse statement does not hold for all figures. It is important to note that the converse of a true statement is not always true, and separate analysis is required to determine the validity of the converse in specific cases.
