Answer:

 The chance that positive response obtained for program 1 is 65.90

And  The chance that positive response obtained for program 2 is 87.50  

Step-by-step explanation:

Given data as :

The positive response for program of different cities in percentage

Now, The positive response is obtained from Chicago for program 1 is 65.90

The total positive response for program 1 in % = 68.80

So, The chance that positive response obtained = 65.90

Again ,

The positive response is obtained from Chicago for program 2 is 87.50

The total positive response for program 1 in % = 81.70

So, The chance that positive response obtained = 87.50

Hence   The chance that positive response obtained for program 1 is 65.90

And  The chance that positive response obtained for program 2 is 87.50  answer

Final answer:

After 60 years, with an initial deposit of $370 at a 2% interest rate compounded quarterly, the amount in the savings account would be approximately $996.26. This amount does not triple the initial savings, as it is less than $1110.

Explanation:

To calculate the amount of money in the savings account 60 years later with an initial deposit of $370, an interest rate of 2% compounded quarterly, we use the compound interest formula:
A = P(1 +  rac{r}[tex]{n})^{nt}[/tex]
Where:

A is the amount of money accumulated after n years, including interest.

P is the principal amount (the initial amount of money).

r is the annual interest rate (decimal).

n is the number of times that interest is compounded per year.

t is the time the money is invested for in years.

In this case:

P = $370

r = 0.02 (2% as a decimal)

n = 4 (since the interest is compounded quarterly)

t = 60

So, the equation becomes:

A = 370(1 +  rac{0.02}[tex]{4})^{4 imes 60}[/tex]
A = 370[tex](1 + 0.005)^{240}[/tex]
A = 370[tex](1.005)^{240}[/tex]
A = 370(2.69259) = $996.26 (rounded to two decimal places)

So, after 60 years, the amount in the account would be approximately $996.26. To check if the savings have tripled:

370 imes 3 = $1110

Since $996.26 is less than $1110, the savings have not tripled.

Step-by-step explanation:

Part 6)

a) How much edging is needed?

we know that

To find out how much edging is needed determine the circumference of the circular garden

The circumference of the circular garden is equal to

[tex]C=\pi D[/tex]

where

D is the diameter

we have

[tex]D=2.4\ m[/tex]

assume

[tex]\pi =3.14[/tex]

substitute

[tex]C=(3.14)(2.4)[/tex]

[tex]C=7.536\ m[/tex]

Part b) we know that

To find out the cost to edge the garden, multiply the length of edging plastic needed by the cost of $4.53 per meter

so

[tex](7.536\ m)(4.53\ \$/m)=\$34.14[/tex]

Answer:

37.5 miles

Step-by-step explanation:

4in = 25 miles

1in = 25/4

4 + 2 = 6

6 = 25 +(6.25*2)

6 = 37.5

To find the distance represented by a line segment on a scale drawing, set up a proportion and solve for x.

To determine the distance represented by a line segment on the scale drawing, we can set up a proportion using the given information. Since 4 inches represents 25 miles, we set up the proportion 4/25 = 6/x, where x represents the distance represented by the line segment. To find x, we can cross-multiply and solve for x: 4x = 150, and dividing both sides by 4 gives x = 37.5. Therefore, the line segment represents a distance of 37.5 miles.

The rule for determining the cost based on the number of tickets is Cost = 30 × Tickets. Using this rule, the cost for 10 tickets is calculated to be 300 dollars.

Explanation:

The question requires us to determine a rule for the output based on the given input of tickets and then use this rule to find the cost for 10 tickets. By examining the input and output values provided, we see a consistent pattern: the cost increases by 30 dollars with each additional ticket. Given this pattern, the rule can be formulated as an algebraic expression: Cost = 30 × Tickets.

Applying this rule to an input of x tickets, the expression becomes Cost = 30 × x. To find the cost for 10 tickets, we replace x with 10: Cost = 30 × 10 = 300 dollars.

Step-by-step explanation:

Let the total bill be "x"

Now,

Anna paid 40% (40/100 = 0.4) of the bill, that means

Cassie paid 100 - 40 = 60% of the bill, that is 60/100 = 0.6

Anna paid 0.4x  &  Cassie paid 0.6x

Cassie's amount is 8 dollar more, so we can write:

0.6x - 8 = 0.4x

Now, we solve for x:

0.6x - 0.4x = 8

0.2x = 8

x = 8/0.2

x = 40

THe total bill is $40

Answer:753

Step-by-step explanation:

The value of [tex]n^{th}[/tex] term can be calculated by,

[tex]T_{n} = a+(n-1)d\\[/tex]

where,

a = first number of the series

d = constant difference between the numbers

So, according to the question,

a = -6

d = 11

n = 70

hence, by substituting,

[tex]T_{n} = (-6)+(70-1)11\\T_{n} = 753[/tex]

Final answer:

The 70th term of the arithmetic sequence -6, 5, 16 is calculated using the formula for the nth term of an arithmetic sequence, resulting in the 70th term being 753.

Explanation:

The student is asking for the 70th term of the arithmetic sequence -6, 5, 16. In an arithmetic sequence, the difference between consecutive terms is constant. This difference is referred to as the common difference "d". The formula for finding the nth term an of an arithmetic sequence is:

an = a1 + (n - 1)d

Using the provided sequence, we can find the common difference by subtracting the first term from the second term:

d = 5 - (-6) = 11

Now, apply the formula to find the 70th term:

a70 = a1 + (70 - 1)  imes d

a70 = -6 + 69  imes 11

a70 = -6 + 759

a70 = 753

Therefore, the 70th term of the given arithmetic sequence is 753.

Answer:

x = 3.576 and x = - 3.076

Step-by-step explanation:

Two functions are given to be, g(x) = 2x² + 3x + 10 and k(x) = 2x + 16.

Now, we have to solve the equation g(x) = 2k(x)  

⇒ 2x² + 3x + 10 = 4x + 32

⇒2x² - x - 22 = 0

The expression in the left hand side can not be factorized and therefore we have to use Sridhar Acharya formula which gives the solutions of the equation in the form ax² + bx + c = 0 are given by  

[tex]x = \frac{-b + \sqrt{b^{2} - 4ac} }{2a}[/tex] and [tex]x = \frac{-b - \sqrt{b^{2} - 4ac} }{2a}[/tex]

Therefore, the solutions of the given equation are  

[tex]x = \frac{-(- 1) + \sqrt{(- 1)^{2} - 4 (2)(-22)}  }{2(2)} = 3.576[/tex]

and [tex]x = \frac{-(- 1) - \sqrt{(- 1)^{2} - 4 (2)(-22)}  }{2(2)} = -3.076[/tex] (Answer)

Final answer:

To solve the equation g(x) = k(x) for x, we simplify it to 2x² + x - 6 = 0 and factor it, resulting in x = 1.5 or x = -2. The method used is factoring due to the simplicity of the equation.

Explanation:

To solve the equation g(x) = k(x) algebraically for x, we set the given functions equal to each other. Given the functions g(x) = 2x² + 3x + 10 and k(x) = 2x + 16, the equation becomes 2x² + 3x + 10 = 2x + 16. To solve for x, we must first simplify the equation by moving all terms to one side and then using the quadratic formula or factoring, if possible.

Step 1: Subtract 2x and 16 from both sides to obtain the quadratic equation 2x² + x - 6 = 0.

Step 2: Factor the quadratic equation if possible. In this case, it factors to (2x - 3)(x + 2) = 0, so the possible solutions for x are x = 1.5 or x = -2.

The chosen method for solving this quadratic equation is factoring because the equation simplifies nicely and the factors are easily observable.

Answer:

The apothem is also the radius of the incircle of the polygon. For a polygon of n sides, there are n possible apothems, all the same length of course. The word apothem can refer to the line itself, or the length of that line. So you can correctly say 'draw the apothem' and 'the apothem is 4cm'.

Final answer:

To find the apothem in geometry, one must utilize trigonometry, knowing the polygon's side length. In astronomy, calculating distances such as the semi-major axis involves understanding celestial mechanics and requires knowing the aphelion and perihelion distances. The problem content combines concepts from geometry and astronomy to discuss angles and distances.

Explanation:

Calculating the Measure of the Apothem

When attempting to find the measure of the apothem of a geometric figure, you're essentially looking for a segment that connects the center of the figure to the midpoint of one of its sides and is perpendicular to that side. This is especially common in regular polygons. However, this particular problem seems to blend geometry and astronomy, discussing the apparent width of the Moon and comparing it using similar triangles.

To calculate the apothem in a regular polygon, you can use trigonometry if you know the length of one of the sides and the number of sides. On the other hand, if the setting involves celestial bodies like the moon and planets, determining an apothem-like distance would involve understanding the object's orbit, size, and distance from the observer.

To compute the semi-major axis of an elliptical orbit, like that of a planet around a sun, you would use the sum of the aphelion and perihelion, divided by two. For instance, if we know the perihelion (rp) and aphelion (ra), we calculate the semi-major axis (a) as (ra + rp)/2.

Remember, an angle is used in astronomy to measure the apparent separation between celestial objects as seen from Earth. Astronomers use degrees to describe these angles, and knowing the angular size can help in estimating distances in space.

To find the aphelion or semi-major axis of an orbit, certain equations are used that involve these distances. Such calculations are essential for understanding celestial mechanics and the movement of objects in our solar system.

Answer:

Tommy and Manuel are 16 ft apart

Step-by-step explanation:

The locations of all three players are shown in the image below

They form a right triangle where the hypotenuse is 20 ft, and one of the legs is 12 ft. We must find the other leg.

We must use Pythagoras's theorem. Being a and b the legs of a right triangle and c its hypotenuse, then

[tex]c^2=a^2+b^2[/tex]

Knowing c and one of the legs, say b:

[tex]a^2=c^2-b^2[/tex]

Using the values c=20, b=12 we find

[tex]a^2=20^2-12^2=400-144=256[/tex]

[tex]a=\sqrt{256}=16[/tex]

So, Tommy and Manuel are 16 ft apart
