Answer:

For the first two problems, there is nothing that I should solve for, lmk and I will solve it again. For now, I just solved for the sector.

Step-by-step explanation:

1. s=(7pi)/2

2. s=14pi/5

3. 240

4. s=((pi)r(<APC))/180

the circumference of the circle is 20pi and ABC is 16pi so the minor arc AC is 4pi=s

4pi=(pi)(10)(x)/180

x=72

Hope that helps :)

Use the below formula of Arc length

L=Ø/180×πr

126/180(π(5))126π/367π/2

84/180π(6)84π/3014π/5

Ø=111+129=240°

240/180(π(6)240π/308π

L=Ø/180(πr)Ø=180L/πr

Ø=

180(16π)/π(10)18(16)288°

How does a quadratic function relate to volleyball and what aspects of quadratic functions are there?

Answers

Answer:

Volleyball players want to keep their serves as close to the net as possible, so the ball travels for a shorter period of time. Say a volleyball player serves the ball across the court. If we can model this situation with the function y=-0.006(x−21)2+9, where x is the distance from the player and y is the height, then we can determine if the ball clears the net and lands in bounds 61 feet away1. It may be helpful to analyze this situation graphically, and we consider how to do that in this section.

In a biology lab, 500 bacteria reproduce by splitting. Every hour, on the hour, each bacterium splits into two bacteria.

Answers

Answer:hour 1 500, hour 2 1000, hour 3 2000 , hour 4 4000

Step-by-step explanation:

After 1 hour 500 bacteria split into 500 bacteria.

After 2 hour 500 bacteria split into 1000 bacteria.

After 3 hour 500 bacteria split into 1500 bacteria.

After 4 hour 500 bacteria split into 2000 bacteria.

Given that,

In a biology lab, 500 bacteria reproduce by splitting.

Every hour, on the hour, each bacterium splits into two bacteria.

We have to find,

Find the number of bacteria after 4 hours.

According to the question,

Let us assume n = the number of bacteria at a given hour.

Total number of bacteria = 500

At the end of 1 hour each of the 500 bacteria after an hour is split in to 2 bacteria. So, at the end of 1 hour = n(1) = 1 × 500 = 500 After 1 hour 500 bacteria split into 500 bacteria.

At the end of the 2 hour, each of the 500 bacteria will split in to 2 more bacteria. So, n(2) = 2 x 500 = 1000 bacteria After 2 hour 500 bacteria split into 1000 bacteria.

At the end of the 3 hour, each of the 500 bacteria will split in to 2 more bacteria. So, n(3) = 500 x 3 = 1500 bacteria After 3 hour 500 bacteria split into 1500 bacteria.

At the end of 4 hours, each of the 500 bacteria spilt into 2 more bacteria.

So, n(4) = 4 × 500 = 2000 bacteria

After 4 hour 500 bacteria split into 2000 bacteria.

The population of bacteria can be modeled by the function below, where t represents the time since the population started decaying and f(t) represents the population of the remining bacteria at time t. What is the rate of decay for this population?

Answers

Answer:

See Explanation

Step-by-step explanation:

The question is incomplete. I will assume the function is:

[tex]f(t) = 15(0.86)^t[/tex]

Required

Determine the rate of decay

In an exponential function [tex]f(x) = ab^x[/tex],

The decay rate of the function is calculated as:

[tex]1 - r = b[/tex]

By comparison:

[tex]b = 0.86[/tex]

So, the equation becomes:

[tex]1 - r = 0.86[/tex]

Make r the subject

[tex]r = 1 - 0.86[/tex]

[tex]r = 0.14[/tex]

The rate of decay is 0.14

Glenn needs to cut pieces of ribbon that are each 1 meter long to make ribbon key chains. If he has 6 pieces of ribbon that are each 1 dekameter long, how many 1−meter pieces of ribbon can he cut?

Answers

Answer:

2/3

Step-by-step explanation:

Glenn needs to cut pieces of ribbon that are each 1 meter long to make ribbon key chains. If he has 6 pieces of ribbon that are each 1 dekameter long, how many 1−meter pieces of ribbon can he cut?

1 decametre = 10 metres

Hence,

10 meters = 6 pieces of ribbon

1 meter = x pieces

Cross Multiply

10x = 6

x = 6/10

x = 2/3 (1 meter pieces of ribbon)
