Answers

Answer 1

Answer:

C. r = 3 - cos theta

Step-by-step explanation:

The other user who answered was correct.

Answer 2

The equation is belongs to the graph of the limacon curve is r = 3 - cos [tex]\theta[/tex]

The correct option is C.

At θ = 180°, the value of r is positive, but just a fraction of the value at

θ = 0°. This eliminates choices 'b' and 'd'.

As, the equation of a horizontal cardiod is r= a ± a cos θ.

Here, from the figure we have horizontal cardiod.

Then, the equation is belongs to limacon curve is r = 3 - cos [tex]\theta[/tex].

what is the smallest number of integer kilogram weights needed to weigh every whole kilogram between 1kg and 40kg?

Answers

9514 1404 393

Answer:

Step-by-step explanation:

We assume you are using a balance, and that weights can be put in either pan. In that case, weight values can be either added or subtracted, so there are 3 possibilities for the contribution each weight makes. In other words, we need to find how many digits are required to count to 40 in base 3.

The largest 3-digit number in base 3 is ...

3^2 +3^1 + 3^0 = 13 (base 10)

The largest 4-digit number adds 3^3 = 27 to this: 27 +13 = 40.

Hence, we can weigh values 0 to 40 using 4 weights, of sizes 1, 3, 9, 27.

Some example weights are ...

5 = 9 - 3 - 1

38 = 27 + 9 + 3 - 1

where the "negative" weights are placed in the same pan as the unknown.

Find the common difference of the arithmetic
sequence 13,9,5,

Answers

Answer: -4

Step-by-step explanation:

13 - 9 = 4

9 - 5 = 4

so, we can see that it is decreasing by 4 each time.

Answer:

common difference is -4

Step-by-step explanation:

The common difference is the amount we add between terms

13 + d = 9

Subtract 13 from each side

13+d-13 = 9-13

d = -4

Check

9+d = 5

9 + -4 = 5

5= 5

This is true so the common difference is -4

Common difference, d = -5

We need to find the fifth term of the sequence.

The nth term of the sequence is given by :

[tex]a_n=a+(n-1)d[/tex]

Put n = 5, a = 8 and d = -5 in the above formula

Find the future value if £1500 is invested for 5 years at 8.7% p.a.

Answers

Answer:

$2,152.50

Step-by-step explanation:

A = $2,152.50

I = A - P = $652.50

Equation:

A = P(1 + rt)

Calculation:

First, converting R percent to r a decimal

r = R/100 = 8.7%/100 = 0.087 per year.

Solving our equation:

A = 1500(1 + (0.087 × 5)) = 2152.5

A = $2,152.50

The total amount accrued, principal plus interest, from simple interest on a principal of $1,500.00 at a rate of 8.7% per year for 5 years is $2,152.50.

Answers

Answer:

Step-by-step explanation:

1) Number of children = c

Number of adults = a

Total ticket = 250

c + a = 250 -------------------(I)

Cost of 'c' children tickets = 200c

Cost of 'a' adult tickets = 450a

Total cost = 76000

200c + 450a = 76000 ------------------(II)

Multiply (I) by (-200) and then add

(I)*(-200) -200c - 200a = -50000

(II) 200c + 450a = 76000

250a = 26000

a = 26000/250

a = 104

Plug in a = 104 in equation (1)

c + 104 = 250

c = 250 - 104

c = 146

2)Number of children = 146

Number of adults = 104

They made a difference in people's lives and learned some important life lessons in the process. Organizations, including schools, are actively promoting service for all citizens as a way to be involved, help others, and improve themselves.Service is helping other people and being active in your community. For example, one group of teens planted a community garden with their friends. They grow a variety of vegetables. The garden requires regular care. The teens donate the produce to a local soup kitchen. Workers there use the produce to help feed people in the community. By tending the garden and donating their produce, the teens are actively helping make life a bit better for others in their community.Service is valuable in ways that cannot be measured in dollars. People volunteer or serve others without expecting money or gifts in return. Service is not about earning money. It is not just collecting money to give to a group. It is about action and contributing to the common good. The people who serve as well as those who receive help benefit in many ways that are more important than money or gifts. For example, a soup kitchen provides essential food to people who may otherwise go hungry. The soup kitchen is extremely valuable for those struggling to get enough to eat. Those serving learn about compassion and how helping others can improve life for all.Millions of Americans are making society better for themselves and for others.
