Consider the unit circle, which is the circle of
radius 1 centered at the origin. Which of the
following properties of the circle are
invariant (that is, does not change) under a
rotation?
Select one or more:
a. The radius of the circle
b. The measure of an angle with vertex
on the center of the circle
c. The area of the circle
d. The circumference of the circle
Answer:
It is between B and C but what I would choose is C.
The radius, area and circumference of the circle is invariant properties of the circle. Option a, c and d to be chosen.
Properties to be determine that would not change after the rotation of circle.
Circle is locus of the point whose distance from the fixed points i.e. center is fixed.
Here, circle has unit radius and center at origin. If the circle is rotated along the point any where in the space the propertied that would be fixed is its radius, area and circumference.
Thus, the radius, area and circumference of the circle is invariant properties of the circle.

Use a net to find the surface area of the open cylinder with only one base. Use 3.14
(round to the nearest tenth as needed)
Answer:
706.5 cm²
Step-by-step explanation:
Surface area of the open cylinder with only one base = surface area of cylinder - area of one of the base
= 2πr(h + r) - πr²
Where,
r = 9 cm
h = 8 cm
π = 3.14
Plug in the values into the equation
Area of the open cylinder with one base = 2*3.14*9(8 + 9) - 3.14*9²
= 56.52(17) - 254.34
= 960.84 - 254.34
= 706.5 cm²

A bank's loan officer rates applicants for credit. the ratings are normally distributed with a mean of 200 and a standard deviation of 50. if an applicant is randomly selected, find the probability of a rating that is between 200 and 275. your answer should be a decimal rounded to the fourth decimal place.
Answer:
the probability of a rating that is between 200 and 275 is 0.4332
Step-by-step explanation:
Given the data in the question;
if an applicant is randomly selected, the probability of a rating that is between 200 and 275
mean μ = 200
standard deviation σ = 50
P( 200 < X < 275 ) = P( X-μ / σ < x-μ / σ < X-μ / σ )
P( 200 < X < 275 ) = P( 200-200 / 50 < x-μ / σ < 275-200 / 50 )
= P( 0/50 < Z < 75/50 )
= P( 0.00 < Z < 1.50 )
P(Z < 1.50) - P(Z < 0.0)
from the standard normal table
P(Z < 1.50) = 0.9332
P(Z < 0.0) = 0.5000
so
P( 200 < X < 275 ) = 0.9332 - 0.5000
P( 200 < X < 275 ) = 0.4332
Therefore, the probability of a rating that is between 200 and 275 is 0.4332

Identify the correct table for the following equation: Y=3x + 7 ( look at the picture for answer choices )
Answer:
The first choice is the right answer.
Step-by-step explanation:
Y = 3x+7
First choice
y = 3(0) + 7 = 7
y = 3(1) + 7 = 10
y = 3(2) + 7 = 13
second choice
y = 3(7) + 7 = 28. output on table shows 0
third choice
y = 3(0) + 7 = 7
y = 3(1) + 7 = 10 doesn't work as y output in third choice says 8
fourth choice.
y = 3(7) + 7 = 28 output on table shows 0

question is given below:
(a) List all the possible outcomes
A dice has 6 sides, ranging from numbers 1 to 6.
As such, the possible outcome for 1 dice is 1, 2, 3, 4, 5 and 6.
Since 2 dice are used, the possible outcome increases, ranging from 2 to 12.
Working:
1 + 1 = 2 (MIN)
6 + 6 = 12 (MAX)
Therefore, the possible outcomes is from 2 to 12.
(b) Find the probability of getting an even number as a score
Total number of score = 11
Total number of even score = 6
P (even number) = 6 / 11
I believe this should be the correct answer... seems logical to me. HAHA. Anyway, do let me know if I am correct or have any queries :)

suppose you deposit $1000 in a savings account that pays 4.8% interest compounded monthly. Write an exponential function to model the amount of money in your savings account. How much will you have in your account after 2 years?
Answer:
The exponential function is [tex]A(t) = 1000(1.004)^{12t}[/tex].
You will have $1,100.55 in the account after 2 years.
Step-by-step explanation:
Compound interest:
The compound interest formula is given by:
[tex]A(t) = P(1 + \frac{r}{n})^{nt}[/tex]
Where A(t) is the amount of money after t years, P is the principal(the initial sum of money), r is the interest rate(as a decimal value), n is the number of times that interest is compounded per year and t is the time in years for which the money is invested or borrowed.
Deposit $1000 in a savings account that pays 4.8% interest compounded monthly.
This means that [tex]P = 1000, r = 0.048, n = 12[/tex]. So
[tex]A(t) = P(1 + \frac{r}{n})^{nt}[/tex]
[tex]A(t) = 1000(1 + \frac{0.048}{12})^{12t}[/tex]
[tex]A(t) = 1000(1 + 0.004)^{12t}[/tex]
[tex]A(t) = 1000(1.004)^{12t}[/tex]
This is the exponential function
How much will you have in your account after 2 years?
This is A(2). So
[tex]A(2) = 1000(1.004)^{24} = 1100.55[/tex]
You will have $1,100.55 in the account after 2 years.
