The figure shown in the image provided is called a sphere. Note that a sphere can be thought of as a round ball. In geometric terms, a sphere is defined as a set of points that are a given distance from a given point. The given point is called the center of the sphere and the given distance from the center of the sphere to the set of points that form the sphere is called the radius of the sphere.

The volume of a sphere can be calculated by the formula that is shown in the second image that is provided below.

Answer:

Part a) The rule of the sequence is $A(n)=50(0.52^{n-1})$

Part b) The height of the ball will be $13.52\ cm$

Step-by-step explanation:

Part a) Write a rule for the sequence using centimeters. The initial height is given by the term n = 1.

we know that

In a <u>Geometric Sequence</u> each term is found by multiplying the previous term by a constant called the common ratio (r)

In this problem we have a geometric sequence

Let

n-----> the number of path

a1 ----> is the initial height

r -----> the common ratio

we have

$a1=0.5\ m=0.5*100=50\ cm$

$r=52\%=52/100=0.52$

The rule for the sequence is equal to

$A(n)=a1(r^{n-1})$

substitute

$A(n)=50(0.52^{n-1})$

Part b) What height will the ball be at the top of the third path?

For n=3

substitute in the equation

$A(3)=50(0.52^{3-1})$

$A(3)=50(0.52^{2})$

$A(3)=13.52\ cm$

Janet and her brother John went out to eat. Both paid the same amount. Janet got three burgers and left a $10 tip. John bought 4

lianna [129]

Answer:

Cost for 1 burger = 5 $

Amount spent by Janet = 25$

Amount spent by John = 25$

Explanation:

Let the cost for burger be p.

Janet got three burgers and left a $10 tip

Amount spent by Janet = 3 p + 10

John bought 4 burgers, but only left a $5 tip

Amount spent by John = 4 p + 5

Both paid the same amount.

So, we have 3 p + 10 = 4 p + 5

=> p = 5 $

So, cost for 1 burger = 5 $

Amount spent by Janet = 3 x 5 + 10 = 25$

Amount spent by John = 4 x 5 + 5 = 25$

Answer:

4 units

Step-by-step explanation:

Distance like magnitude is simply a positive value

----------------------------

Since the y coordinate is the same

the distance is just the difference in the x coordinates

from -5 to -1 is a distance of 4
