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
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

It follows that the distance formula is given as
d

=
(
x

−
x

)

(
y

−
y

)

→
d
=
√
(
x

−
x

)
2
+
(
y

−
y

)

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
(
x

, the distance between two points is given by

Step-by-step explanation:
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
Okay I tried to work it without a picture of the triangle BUT
the answer should be <span>sinB = 0.97752</span>
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.
