To solve this problem, we need to use the formula for the nth term of an arithmetic sequence:
an = a1 + (n-1)d  where a1 is the first term, d is the common difference, and n is the term number.  This means that the first term is 118, the common difference is -6, and each subsequent term is found by subtracting 6 from the previous term.

We know that the 4th term is 100, so we can substitute this into the formula:
a4 = a1 + (4-1)d
100 = a1 + 3d

Similarly, we know that the 13th term is 46:
a13 = a1 + (13-1)d
46 = a1 + 12d
Now we have two equations with two unknowns (a1 and d), which we can solve by elimination or substitution. I will use elimination:
100 = a1 + 3d
-46 = -a1 - 12d
------
54 = -9d
d = -6
Now we can substitute d back into one of the equations to solve for a1:
100 = a1 + 3(-6)
a1 = 118
Therefore, the expression for the general term of the arithmetic sequence is:
an = 118 - 6(n-1) or  an = 124 - 6n

Answer:

10 Quarters and 5 dimes

Step-by-step explanation:

10 Quarters = $2.50

5 dime = $0.50

Answer:

20 dimes and 4 quarters

Step-by-step explanation:

So, a dime is 10 cents and a quarter is 25

So, let's say you have x dimes and y quarters

X+Y=24 (total amount of coins)

Also,

10x+25y= 300 (cents)

I just put the 3 dollars into cents

Now, you have a system of equations and we should solve it:

X+y=24 ----x=24-y

10x+25y=300

So substitute x in the 2nd equation

10(24-y)+25y=300

240-10y+25y=300

240+15y=300

15y=60

y=4

Now that you know the amount of quarters, you can just say that you will have 20 dimes since 24-4=20

So, 4 quarters and 20 dimes

Check:

20 dimes=2 dollars

4 quarters= 1 dollar

Step-by-step explanation:

f(6) it means f(x=6) so substituting x=6 in your equation gives us

f(6)= -4*(6)²+5*(6)

= -4*36+30

= -144+30

= -114

Three-fifths is equivalent to 6/10.

We must build up the equation and solve for the unknown value to determine how many fifths are equal to 6/10.

Let's use "x" to stand in for the unknown value. One way to set out the equation is as follows:

x/5 = 6/10

We can multiply both sides of the equation by 10 to remove the denominators:

10 * (x/5) = 10 * (6/10)

Simplifying:

2x = 6

adding two and dividing both sides of the equation:

2x/2 = 6/2

x = 3

3 fifths are therefore comparable to 6/10.

Thus, There are three-fifths to make 6/10.

Various heuristics and approximation algorithms are used to find near-optimal solutions efficiently in practice.

One example of a decision problem known to be NP-Complete is the "Traveling Salesman Problem" (TSP).

The Traveling Salesman Problem (TSP):

The TSP is a classic problem in computer science and operations research. It involves a salesman who needs to visit a set of cities, each exactly once, and return to the starting city while minimizing the total distance traveled.

Criteria for NP-Completeness:

To be classified as NP-Complete, a decision problem must meet the following two criteria:

a. It must belong to the class of problems known as NP (nondeterministic polynomial time), meaning that a solution can be verified in polynomial time.

b. It must be at least as hard as any other problem in the class NP. In other words, if a polynomial-time algorithm is found for one NP-Complete problem, it would imply polynomial-time solutions for all other NP problems.

Solution to the Optimization Problem:

The corresponding optimization problem for the TSP is to find the shortest possible route that visits all cities exactly once and returns to the starting city. The outline of a solution to this problem is as follows:

a. Enumerate all possible permutations of the cities.

b. For each permutation, calculate the total distance traveled along the route.

c. Keep track of the permutation with the minimum total distance.

d. Output the permutation with the minimum distance as the optimal solution.

However, it's important to note that the TSP is an NP-Complete problem, which means that finding an optimal solution for large problem instances becomes computationally infeasible.

The rate of increase of the radius is 0.025 in/sec.

A three-dimensional object with a sphere-like shape. A sphere has no vertices or edges, unlike other three-dimensional shapes. The distances between each point on its surface and its center are equal.

In other words, the distance between any two points on the surface and the sphere's center is equal. The formula for the Volume of the sphere is given by

Volume of sphere = (4/3)πr³

Where, r = radius of the sphere

Here we have

A sphere is increasing in volume at the rate of 20 in³/s.  

Here we need to find at what rate the radius of the sphere increases when the radius is 4 in.

Let v = Volume of the sphere at time t

=> Change in Volume = dv/dt  = 20

r = Radius of the sphere at time t

As we know, the Volume of the sphere, v = (4/3)πr³

Differentiate the Volume of the sphere with respect to t

=> dv/dt = (4/3)3πr³⁻¹)(dr/dt)

=> dv/dt = 4πr² (dr/dt)

=>  20 = 4πr² (dr/dt)  

=>  5 = πr² (dr/dt)  

Given that radius, r = 4

=> 5 = π4² (dr/dt)  

=> 5 = (22/7) 64 (dr/dt)  

=> 5 = 3.14(64) (dr/dt)  

=> dr/dt = (5/3.14 × 64)  

=> dr/dt = 0.024880573

=> dr/dt = 0.025

Therefore,

The rate of increase of the radius is 0.025 in/sec.

To find the volume of the solid generated by rotating the region bounded by the curves y = cos(x) and the x-axis on the interval [0, π/2] about the x-axis, we can use the method of cylindrical shells.

The volume V is given by the integral:

V = ∫[a,b] 2πx f(x) dx

In this case, the interval [a,b] is [0, π/2], and the function f(x) is cos(x).

V = ∫[0,π/2] 2πx cos(x) dx

To evaluate this integral, we can use integration by parts. Let's consider u = x and dv = 2π cos(x) dx. Then du = dx and v = 2π sin(x).

Using the formula for integration by parts, the integral becomes:

V = [2πx sin(x)]|[0,π/2] - ∫[0,π/2] 2π sin(x) dx

Evaluating the definite integral and plugging in the limits, we have:

V = [2π(π/2) sin(π/2)] - [-2π(0) sin(0)] - ∫[0,π/2] 2π sin(x) dx

V = π^2

Therefore, the volume of the solid is π^2 cubic units.

The total cost of canvas required to make the tent at the rate of Rs. 15 per square meter is; Rs. 24,997

We are told that the bottom part of the tent house is a square cuboid up to a height of 10 m.

Thereafter, it is a pyramid.

Now, formula for volume of a cuboid is;

V = lwh

V = 20 * 20 * 10

V = 4000 m³

Formula for volume of a pyramid is;

V = lwh/3

V = (20 * 20 * h)/3

V = 400h/3

Total volume is 4800 of the entire tent house. Thus;

4000 + (400h/3) = 4800

400h/3 = 800

h = (800 * 3)/400

h = 6 m

Now, from online calculation, the surface area of the pyramid excluding the base is;

TSA_p = 466.48 m²

Answer:

In the circle, the measure of the arc AC is 21°.

Step-by-step explanation:

Concept: We can use the Inscribed Angle theorem to get the measure of AC.

Given that the inscribed angle ∠ABC is 3x-1.5 and the Intercepted arc AC is 3x+9.

Inscribed Angle Theorem states that the measure of an inscribed angle is half the measure of the intercepted arc.

So,

3x - 1.5 = 0.5(3x + 9)

6x - 3 = 3x + 9

3x = 12

x = 4

Since the intercepted arc AC is 3x + 9, putting the value of x = 4 we get,

intercepted arc AC is 21°.

Hence the intercepted arc AC is 21°.

Step-by-step explanation:

81-11 is 70. 70 divided by .14 is 500 so that's 500 miles she can bike.

Answer:

500 miles

Step-by-step explanation:

To find out how many miles Candice can hike at max, use the equation 11 + 0.14x = 81.

11 + 0.14x = 81

Subtract 11 from both sides. This undoes the +11.

0.14x = 81 - 11

Subtract 11 from 81 to get 70.

0.14x = 70

Divide both sides by 0.14. This undoes the multiplication by 0.14.

x = 70/0.14

I recommend converting 0.14 into a fraction. That would be 7/50.

x = 70/(7/50)

Find the reciprocal of 7/50 (50/7). Switch the sign from division to multiplication.

x = (70 * 50)/7

Multiply 70 by 50 to get 3500.

x = 3500/7

Divide 3500 by 7 to get 500.

x = 500

At max, Candice can hike 500 miles.

Step-by-step explanation:

If there is a positive correlation between x and y then in the regression equation, y = bx + a, the slope coefficient, b, is positive. When there is a positive correlation between x and y, it indicates that an increase in the value of x corresponds to an increase in the value of y.

Thus, the regression line has a positive slope. The slope coefficient of the regression line, b, is a measure of the change in y associated with a one-unit change in x.

When the correlation is positive, the slope coefficient, b, will be positive in the regression equation, y = bx + a. Therefore, y will increase as x increases.Besides, the intercept, a, in the regression equation represents the expected value of y when x = 0. It is also known as the y-intercept of the regression line.

Step-by-step explanation:

To find the percent change in price of the four new tires, we can use the formula:

percent change = (new value - old value) / old value * 100%

Here, the old value is $638 and the new value is $523.

percent change = ($523 - $638) / $638 * 100%

percent change = -$115 / $638 * 100%

percent change = -0.18 * 100%

percent change = -18%

The result is a decrease of 18%, so the answer is A. 18% decrease.

Okay, let's solve this step-by-step:

Original price of 4 tires: $638

New price of 4 tires: $523

To calculate the percent change, we use the formula:

Percent Change = (New Price - Original Price) / Original Price

So in this case:

Percent Change = ($523 - $638) / $638 = -$115 / $638 = -0.18 = 18%

Since the new price is less than the original price, this is a decrease.

Therefore, the answer is A: 18% decrease
