1 answer:

5 0

X^2 + y^2 = r^2 is the equation f a circle with center at (0,0) and r = radius
x^2 + y^2 = 10^2
center (0,0) and radius = 10

What is the 23rd term of the arithmetic sequence where a1 = 8 and a9 = 48?

yKpoI14uk [10]

$a_1=8$
$a_2=a_1+d=8+d$
$a_3=a_2+d=(8+d)+d=8+2d$
$a_4=a_3+d=(8+d)+2d=8+3d$
...
$a_9=8+8d=48\implies d=5$
$a_{10}=8+9d$
...
$a_{23}=8+22d=118$

Do you think mold is somthing we need to worry about in school

Brrunno [24]

Personally, I think it is. Not only that mold is very unattractive and would not represent your school well, it can cause issues with your respiratory system. It can cause a lot of problems with children that have asthma and allergies or maybe they are sensitive to it. Even for the children who do not have those two, it can cause Illness and infections.

an airplane files 867 miles with a constant speed of 612 mph and then another 1984 miles with a constant speed of 744 mph what i

seraphim [82]

The average speed is the ratio of the total distance to the total time. Then the average speed of the airplane will be 698.19 miles per hour.

<h3>What is speed?</h3>

The distance covered by the particle or the body in an hour is called speed. It is a scalar quantity. It is the ratio of distance to time.

We know that the speed formula

Speed = Distance/Time

An airplane files 867 miles with a constant speed of 612 mph and then another 1984 miles with a constant speed of 744 mph.

Then time taken for the first trip will be

t₁ = 867 / 612

t₁ = 1.4167 hours

Then time taken for the second trip will be

t₂ = 1984 / 744

t₂ = 2.6667 hours

Then the average speed is the ratio of the total distance to the total time.

The total distance will be

Total distance = 867 + 1984

Total distance = 2851 miles

The total time will be

Total distance = 1.4167 + 2.6667

Total distance = 4.0834 hours

Then the average speed will be

Average speed = 2851 / 4.0834

Average speed = 698.19 mi/h
