Point Q has coordinates (5,6). If you rotate Q 90° about the origin, (0,0), what are the coordinates of Q′
Answers
The coordinates of the image after 90° about the origin is (6, -5)
What is a 90 degrees rotation?A 90 degrees rotation denoted by R(90, 0) is a rotation that has the same effect as the 270 degrees counterclockwise of a figure.
How to determine the image of the rotation?The coordinate of the point is given as
(5, 6)
The rotation is given as 90° about the origin
So, we have
(x, y) => (y, -x)
Substitute (5, 6) in (x, y) => (y, -x)
So, we have
(5, 6) => (6, -5)
Hence, the coordinates of the image is (6, -5)

Which tables have a lower unit rate than the rate represented in the equation? y=3/5xThe pictures are the answer choices.
Answers
The unit rate represented in the equation y = 3/5x is the value multiplying x, that is, the unit rate is 3/5.
In order to find the unit rate of each table, we just need to divide the y-values by the x-values.
So, the unit rate of the first table is:
[tex]\frac{y}{x}=\frac{4}{3}[/tex]The value 4/3 is greater than the value 3/5.
In the second table we have that:
[tex]\frac{y}{x}=\frac{4}{5}[/tex]The value 4/5 is greater than the value 3/5;
In the third table, we have that:
[tex]\frac{y}{x}=\frac{18}{31}[/tex]In order to compare this fraction with 3/5, we need to make them be in the same denominator, so we have to calculate the least common multiple of the denominators.
Since 5 and 31 are prime numbers, the LCM is the product of both numbers.
So we have that:
[tex]\begin{gathered} \frac{18}{31}=\frac{18\cdot5}{31\cdot5}=\frac{90}{155} \\ \\ \frac{3}{5}=\frac{3\cdot31}{5\cdot31}=\frac{93}{155} \end{gathered}[/tex]The number 90/155 is lesser than 93/155, therefore 18/31 is lesser than 3/5, so the answer is the third table.
What is the diameter of a circle whose area is 28.3 cm^2
I don't understand this question can someone help me with the answer
Answers
The approximate diameter of the circle is 5.77 cm
Given that :
area of circle = 28.3 cm²
How is Area of circle is calculated ?
Area of circle is calculated using formula :
A= πr²
where "π" represents 3.14 and r is radius. So now, according to given information,
Where Pi = 3.14
Hence,
A= πr²
Substitution the value of A in above formula :
28.3 = πr²
28.3 = 3.14r²
r² =28.3/3.14
r² =8.323
√r²=√8.323
r = 2.885
r = 2.885 cm Approximately.
d = 2r
d = 5.77 Approximately.
Therefore, the diameter of the circle is 5.77 cm

Bellrose Bank charges a monthly maintenance fee of $17 and a check-writing fee of $0.05 per
check. Last year, Patricia wrote 445 checks from her account at Bellrose. What was the total of all
fees she paid on that account last year?
Answers
The amount Patricia paid as fees on on the account last year was $226.25
What makes up the total cost for Patricia?
Patricia pays a fixed monthly maintenance fee of $17 for every month last year, which means that the total annual maintenance fee last year is the monthly maintenance fee multiplied by 12 months, whereas, the annual check-writing fee is the check-writing fee per check multiplied by the number of checks issued last year.
total annual maintenance fee=monthly maintenance fee *12
monthly maintenance fee=$17
total annual maintenance fee=$17*12
total annual maintenance fee=$204.00
annual check-writing fee= check-writing fee per check*number of checks
annual check-writing fee=$0.05*445
annual check-writing fee=$22.25
total fees paid by Patricia last year=$204.00+$22.25

Write an expression to
describe the sequence below. Use n to represent the position of a term
in the sequence, where n = 1 for the first term.
5, 6, 7, 8, ...
Answers
Answer:
n + 4
Step-by-step explanation:
n is being used to describe the position of a term.
We can see that the sequence is increasing linearly by 1.
Since the position of the next term is increasing linearly by 1, all we have to do is look at the first term and subtract 1 from it to get our constant (4).
An equation to think about this better would be
n + C = S
C is the constant we are solving for.
We know n = 1.
S is the number corresponding in the sequence with n.
1 + C = 5
Subtract 1 from both sides to isolate C.
C = 4
1 + 4 = 5 Checks out
