Evaluate geometric series
Answer:
7.50 (nearest hundredth)
Step-by-step explanation:
General form of geometric progression: \(a_n=ar^{n-1}\)
(where \(a\) is the initial term and \(r\) is the common ratio)
Given progression:
\(5\left(\dfrac13\right)^{n-1}\)
Therefore:
\(a=5\)\(r=\dfrac13\)Sum of a geometric series:
\(S_n=\dfrac{a(1-r^n)}{(1-r)}\)
Substituting a = 5, r = 1/3 and n = 10 to find the sum to n = 10:
\(\implies S_{10}=\dfrac{5(1-\frac13^{10})}{(1-\frac13)}\)
\(\implies S_{10}=7.499873987...\)
\(\implies S_{10}=7.50 \textsf{ (nearest hundredth)}\)

Segments MS and QS are therefore congruent by the definition of bisector. Therefore, the correct answer option is: D. MS and QS.
What is a perpendicular bisector?In Mathematics and Geometry, a perpendicular bisector is a line, segment, or ray that bisects or divides a line segment exactly into two (2) equal halves and forms an angle that has a magnitude of 90 degrees at the point of intersection.
This ultimately implies that, a perpendicular bisector bisects a line segment exactly into two (2) equal halves, in order to form a right angle that has a magnitude of 90 degrees at the point of intersection.
Since line segment NS is a perpendicular bisector of isosceles triangle MNQ, we can logically deduce the following congruent relationships;

Complete Question:
The proof that ΔMNS ≅ ΔQNS is shown. Given: ΔMNQ is isosceles with base MQ, and NR and MQ bisect each other at S. Prove: ΔMNS ≅ ΔQNS
We know that ΔMNQ is isosceles with base MQ. So, MN ≅ QN by the definition of isosceles triangle. The base angles of the isosceles triangle, ∠NMS and ∠NQS, are congruent by the isosceles triangle theorem. It is also given that NR and MQ bisect each other at S. Segments _____ are therefore congruent by the definition of bisector. Thus, ΔMNS ≅ ΔQNS by SAS.

if h(x) =x+2/x-2, then dy/dx= ?
Answer: To find the derivative of the function h(x), we can use the quotient rule, which states that if f(x) = u(x) / v(x), then f'(x) = [v(x)u'(x) - u(x)v'(x)] / [v(x)]^2.
Using this rule, we can find the derivative of h(x) as follows:
h(x) = (x + 2) / (x - 2)
h'(x) = [(x - 2)(1) - (x + 2)(1)] / (x - 2)^2 // apply the quotient rule and differentiate numerator and denominator
h'(x) = (-2 - 2x) / (x - 2)^2
Therefore, the derivative of h(x) is h'(x) = (-2 - 2x) / (x - 2)^2.
Step-by-step explanation:
Find the average rate of change of g(x) with respect to x over the intervals [1, 2], [1, 1.5] and [1,1 + h).
The average rate of change of g(x) with respect to x over the intervals [1, 2], [1, 1.5], and [1, 1+h) are 3, 2, and 3 - 2/h, respectively.
To find the average rate of change of g(x) with respect to x over the given intervals, we can use the formula:
average rate of change = (change in output)/(change in input)
where "change in output" is the difference between the output values at the endpoints of the interval, and "change in input" is the difference between the input values at the endpoints of the interval.
For the function g(x), let's assume we have the following values:
g(1) = 3
g(1.5) = 4
g(2) = 6
g(1+h) = 3h + 1
Then we can calculate the average rate of change over the intervals as follows:
[1, 2]:
change in output = g(2) - g(1) = 6 - 3 = 3
change in input = 2 - 1 = 1
average rate of change = (change in output)/(change in input) = 3/1 = 3
[1, 1.5]:
change in output = g(1.5) - g(1) = 4 - 3 = 1
change in input = 1.5 - 1 = 0.5
average rate of change = (change in output)/(change in input) = 1/0.5 = 2
[1, 1+h):
change in output = g(1+h) - g(1) = (3h + 1) - 3 = 3h - 2
change in input = 1+h - 1 = h
average rate of change = (change in output)/(change in input) = (3h-2)/h = 3 - 2/h

there was a total of 400 oranges and mangoes at a fruit stall.3/8 of these fruits were mangoes.each orange was priced at 40 cents,and each mango was priced at 60 cents.how much would mr.mead make if he sold 2/3 of the mangoes and 4/5 of the oranges?
Answer:
First find the number of Mango and oranges. 400 divided by 8 = 50. We use 8 because it is the whole part of the percentage. Since, there is 3/8 mangoes, multiply 50* 3= 150 mangoes and 50*5= 250 oranges.
2/3 of 150=100 mangoes. You would find this by dividing 150/3=50 then multiply by 2.
4/5 of 250= 200 oranges. You would find this by dividing 250/5=50 then multiply by 4.
$.40*100= $40.00 mangoes
$.60*200= $120.00 oranges
Mr. Mead would make $160.00

Help pls George is building a fence around a rectangular dog run. He is using his house as one side of the run. The area of the dog run will be 240 square feet. The length of the run is 30 feet, and the width is (30 minus x) feet. The diagram below shows his plan.
Recall the formulas for area and perimeter: A = lw and P = 2l + 2w.
The width of the dog run is 20 feet.
In the given problem, the length of the dog run is given as 30 feet.
The area of the dog run is also given as 240 square feet.
Using the formula for the area of a rectangle (A = lw), we can solve for the width (w).
Rearranging the formula, we have w = A / l.
Plugging in the values, we get w = 240 / 30 = 8 feet.
Since the width is given as (30 minus x) feet, we can set up an equation:
30 - x = 8. Solving for x, we find x = 22.
Therefore, the width of the dog run is 20 feet (30 - 22 = 8).
In this problem, the length and width of the dog run are defined by the dimensions of the fence being built around it.
The area of the dog run is given as 240 square feet.
By using the formula for the area of a rectangle, we can solve for the width. We are also given that the length is 30 feet.
Setting up an equation with the given width (30 minus x) and solving for x, we find that x is equal to 22.
This means that the width of the dog run is 8 feet. The main answer to the problem is that the width of the dog run is 20 feet (30 - 22 = 8).

The cost of operating the Marketing Department is allocated to four departments based on the floor space each occupies, in m2. Department A occupies 1400 m2, Department B occupies 820 m², Department C occupies 560 m2, and Department D occupies 390 m². If the cost of operating for March was $19 000. how much of the cost should each department of the Marketing Department take up?
The cost of each department A, B, C, and D of the Marketing Department would take up is $8,391.17, $4,914.83, $3,356.47, and $2,337.53, respectively.
What is a Fraction?A fraction is a way to describe a part of a whole. such as the fraction ¼ can be described as 0.25.
Given the cost of operating the marketing Department for March is $19,000. The total area of operation is,
Total Area = Department A + Department B + Department C + Department D
Total Area = 1400 m² + 820 m² + 560 m² + 390 m² = 3,170 m²
Now, the cost of operating a unit area can be determined as,
Cost of operating = $19,000/3,170m² = $5.99369 per m²
Further the cost of operating the different departments are,
Department A = 1400m²×$5.99 = $8,391.17
Department B = 820m²×$5.99 = $4,914.83
Department C = 560m²×$5.99 = $3,356.47
Department D = 390m² × $5.99 = $2,337.53
Hence, the cost of each department A, B, C, and D of the Marketing Department would take up is $8,391.17, $4,914.83, $3,356.47, and $2,337.53, respectively.

Answer:
Angle A = tan^-1(11/5)
Angle C = 90 - tan^-1(11/5)
AC = sqrt(146)
Step-by-step explanation:
As this is a right triangle, we can apply the Pythagorean theorem a^2 + b^2 = c^2, where c is the hypotenuse while a and b are the legs, to solve for AC.
11^2 + 5^2 = AC^2
121 + 25 = AC^2
146 = AC^2
sqrt(146) = AC^2
Next, to find angle A, we can use one of the trigonometric functions. Let’s use tangent for simplicity. Tangent of an angle is “opposite divided by adjacent”. If we set the angle to A, opposite is side BC and the adjacent is side AB. Thus, tan(A) = 11/5 and tan^-1(11/5) = A.
Since the sum of angles in a triangle is 180, we can find angle C by setting up this equation: C = 180 - 90 - tan^-1(11/5), which is 90 - tan^-1(11/5)
