A circle has a radius of 12 cm. If the radius of the circle is increased by a factor of 7, how many times larger will the circle
-Dominant- [34]

Answer:

The circumference is also 7 times larger

12 cm radius :2*pi*12= 75.43

12*7=84

84cm radius: 2*pi*84= 528

To check if its indeed 7 times larger: 528/75.43 and you'll get 7

If youre looking for the difference between the two: 528-75.43= 452.57

Why is it important to calculate the distance between two points on a cartesian coordinate plane?
Gwar [14]

Answer:

Derived from the Pythagorean Theorem, the distance formula is used to find the distance between two points in the plane. The Pythagorean Theorem,

a

2

+

b

2

=

c

2

, is based on a right triangle where a and b are the lengths of the legs adjacent to the right angle, and c is the length of the hypotenuse. The relationship of sides

|

x

2

−

x

1

|

and

|

y

2

−

y

1

|

to side d is the same as that of sides a and b to side c. We use the absolute value symbol to indicate that the length is a positive number because the absolute value of any number is positive. (For example,

|

−

3

|

=

3

. ) The symbols

|

x

2

−

x

1

|

and

|

y

2

−

y

1

|

indicate that the lengths of the sides of the triangle are positive. To find the length c, take the square root of both sides of the Pythagorean Theorem.

c

a

b

c

√

a

b

It follows that the distance formula is given as

d

=

√

(

x

−

x

)

2

+

(

y

−

)

2

We do not have to use the absolute value symbols in this definition because any number squared is positive.

A GENERAL NOTE: THE DISTANCE FORMULA

Given endpoints

(

x

,

y

)

and

(

,

)

, the distance between two points is given by

You buy a used car for $10,000. The value of the car decreases by22% each year. Approximately how much is the car worth in 3 yea
IRINA_888 [86]

Answer:

The value will be $3,400 after 3 years

Step-by-step explanation:

Convert the percentage into the cash decrease each year, multiply that by 3 and then subtract $10,000 by the sum.

.22 x 10,000 = 2,200

2,200 x 3 = 6,600

10,000 - 6,600 = 3,400

A sample of n = 25 n=25 diners at a local restaurant had a mean lunch bill of $16 with a standard deviation of σ = $ 4 σ=$4 . We
Jobisdone [24]

Answer:

None of the answer options are correct.

Step-by-step explanation:

A confidence interval of the mean is a range within is expected to find the population mean, with a certain degree of confidence.

In this case, the population mean is the average price for a lunch for a n=25 sample.

The interpretation of a 95% confidence interval of (14.43,17.57) should be that there is a 95% of confidence that the population mean (average price for a lunch out of a sample of 25 lunches) is within this interval.
