explanation:

the equation to find circumference is [tex]2\pi (radius)[/tex]

the circumference of A is [tex]2\pi 8 = 50.27[/tex]

the circumference of B is [tex]2\pi 4 = 25.13[/tex]

50.27/25.13 = 2/1

Step-by-step explanation:

To graph an equation using the slope and y-intercept, 1) Write the equation in the form y = mx + b to find the slope m and the y-intercept (0, b). 2) Next, plot the y-intercept. 3) From the y-intercept, move up or down and left or right, depending on whether the slope is positive or negative.

Answer: Because the initial value is $26.40, the line must pass through this when x is 0. Thus, the answer is either the first or the second equation.

Next, we calculate the difference between the year 2019 and 1998 and substitute it into the value of x.

2019 - 1998 = 21.

Substituting this into the equation:

y = 1.006(21) + 26.40

y = $47.52

Thus, the first option is correct.

Answer:

the answer is A

The description and definition and values of the sequence are;

a. Each term of sequence A is produced from the previous term by multiplying the previous term by 2

b. Each term of sequence B is produced from the previous term by adding 10 to the previous term

c. [tex] A(n) = \frac{1}{2} \times 2^{(n-1)} [/tex]

d. B(n) = 2 + (n-1) × 10

e. B(9) > A(9)

A sequence is series of objects that follow each other in a particular order.

a. The terms of sequence A are;

1/4, 1/2, 1, 2, 4

Therefore, each term is produced from the previous term by multiplying the previous term by 2 as follows;

1/4 × 2 = 1/2,

1/2 × 2 = 1

1 × 2 = 2

2 × 2 = 4

b. The values in sequence B are;

2, 12, 22, 32, and 42

Therefore, each term is produced from the previous term by adding 10 to the previous term as follows;

c. The definition of the nth term of sequence A is found using the formula for a geometric progression as follows;

nth term of a GP is; A(n) = a•r^(n-1)

Where;

a = The first term = 1/4

r = The common ratio = 1/2/(1/4) = 2

The nth term of sequence A is therefore;

d. The definition of the nth term of sequence B is found using the formula for a arithmetic progression as follows;

nth term of a AP is; B(n) = a + (n-1)•d

Where;

a = The first term = 2

d = The common difference = 12 - 2 = 10

The nth term is therefore

B(n) = 2 + (n-1) × 10

e. The value of A(9) is therefore;

[tex] A(9) = \frac{1}{2} \times 2^{(9-1)} = 64 [/tex]

Which gives; A(9) = 64

The value of B(9) = 2 + (9-1) × 10 = 82

B(9) = 82

Which gives;

B(9) = 82 > A(9) = 64

From the given Alex and Joey  hats equation we got Alex has 24 hats Joey has 11 hats.

Given that,

Joey only has 2 times more hats than Alex, who has 2 more. The difference between the amount of hats Alex has and the 5 that Joey has is also 4 times the number of hats Alex has.

We have to discover how many hats each one of them has.

Let Alex has x hats Joey has y hats.

From the given

We get

x=2y+2 ------> equation (1)

x=4(y-5) --------> equation (2)

Equating equation (1) and equation (2)

2y+2=4(y-5)

2y+2=4y-20

2y-4y=-20-2

-2y=-22

y=-22/-2

y=11

Take y=11 in equation (1)

x=2(11)+2

x=22+2

x=24

Answer:

2/27

Step-by-step explanation:

i think this is the answer.

the correct option is:

"On a coordinate plane, an exponential function decreases from quadrant 2, through quadrant 3, into quadrant 4 and approaches y = negative 2. It crosses the y-axis at (0, negative 1)"

Here we have the exponential function:

g(x) = (2/3)^x - 2

Now, remember that for any real number different than zero, we have that:

x^0 = 1

So if we evaluate our function in x= 0 we will get:

g(0) = (2/3)^0 - 2 = 1 - 2 = -1

Then the function passes through the point (0, -1)

With this in mind, we conclude that the correct option is:

"On a coordinate plane, an exponential function decreases from quadrant 2, through quadrant 3, into quadrant 4 and approaches y = negative 2. It crosses the y-axis at (0, negative 1)"

Question :-  Daisy is making solid spikes for her Halloween costume. the spikes are shaped like right circular cones with base radius of 2 inches and height of 6 inches. if daisy has 360 cubic inches of material for making the spikes, what is the maximum number of spikes she can make ?

Answer:- She can only create a maximum of 14 spikes.

Step-by-step explanation:

Given that :-

To find :-

According to Question,

We have,

For finding the maximum number of spikes,

We have to divide the volume of the material by the volume of the cone, for producing a maximum number of spikes.

So,

        Maximum spikes = Volume of the material / volume of the cone

Now,

      Volume of the material = 360 cubic inches

       Volume of the cone  = [tex]\frac{1}{3}[/tex] πr²h

Where:

       r = radius = 2 in

      h = height = 6 in

      π = pi = 22/7

         =  [tex]\frac{1}{3}[/tex] × [tex]\frac{22}{7}[/tex] × [tex]2^{2}[/tex] ×6

         = 3.14 × 4 × 2

         = 25.12

So,

        Maximum spikes = Volume of the material / volume of the cone

                                      = [tex]\frac{360}{25.12}[/tex]

                                      = 14.33

∴ The number of spikes must be an integer.

∵          Maximum spikes = 14.

Answer:- She can only create a maximum of 14 spikes.

Given that,

To one decimal place, round.

The standard equation of the circle will be (x+5)²+(y+5)²= 145

The center of the circle, which is the midpoint between those two locations, may be found first since you know the diameter endpoints.

formula for the midpoint

= ((x1+x2)/2, (y1+y2)/2)

Given points are - (3, 4), (−13, −14)

The circle's center is at (-5,-5)

Therefore, the circle's equation will take the form (x+5)²+(y+5)²=R², where R is the circle's radius.

The distance between a point on the circle and the circle's center in order to get the radius.

Therefore, let's calculate the distance between (-5, -5) and (-13,-14)

Radius R = √((-13+5)²+(-14+5)²) using the distance formula.

= 12.04
