The radius of a circle is 17 centimeters. What is the circle's circumference?
Answer:
The circle's circumference is approximately 106.81 centimeters.
Explanation:
The formula for the circumference of a circle is C = 2πr, where C is the circumference, π is pi (approximately 3.14), and r is the radius of the circle.
So, for a circle with a radius of 17 centimeters, its circumference can be found by:
C = 2πr
C = 2 x 3.14 x 17
C ≈ 106.81 cm
Therefore, the circumference of the circle is approximately 106.81 centimeters.

Calculate the geometric center of the grapg under the function
The geometric center of the graph under the function is 5/3
How to determine the geometric center of the graph under the function?The equation of the function is given as:
f(x) = 3 - |x - 2|
The interval is given as:
x ∈ [0, 3]
The geometric center (gc) of the graph under the function is calculated using
gc = ∫x f(x) dx/∫f(x) dx
Substitute the known values in the above equation
gc = ∫x * (3 - |x - 2|) dx/∫3 - |x - 2| dx
Integrate the numerator and the denominator of the above equation
gc = [-1/6(x - 2)((2|x -2| - 9)x + 2|x - 2| - 18)]/[3x - 1/2[|x - 2|(x - 2)]]
Recall that the interval is given as x ∈ [0, 3]
Substitute the interval values in the above equation.
The equation is then simplified using a graphing calculator.
So, we have
gc = (65/6)/(13/2)
Express the quotient expression as a product
gc = (65/6) * (2/13)
Divide 65 by 13
gc = 5/6 * 2
Divide 2 by 6
gc = 5/3
Hence, the geometric center of the graph under the function is 5/3

Denise bikes 3 miles to her friend's house, and then she bikes home. The average rate biking to her friend's house is twice the average rate coming home. Write and simplify an expression for the time it takes Denise to make a round-trip in terms of the average rate coming home x.
Hint : Use d = rt.
The total time for the trip is:
T = 3mi*( 3/2x).
Where x is the rate at which she comes home.
How to find the time for the total trip?
Remember the relation:
distance = rate*time.
We know that the distance is 3 miles (done twice).
First, the rate is 2x and then the rate is x, then the time it took the first half is:
t = 3mi/2x
And for the coming back:
t = 3mi/x
Then the total time for the trip is:
T = 3mi/2x + 3mi/x = 3mi( 1/2x + 1/x) = 3mi*( 3/2x).

suppose we have a card with apr of 30% the mininum payment is 8% of the balance suppose we have a balance of 400 on the credit card we decide to stop charging and pay it off by making the monthly payment each month
The total amount paid in the first month would be $32 for the minimum payment plus $9.20 for the interest, totaling $41.20.
If you have a credit card with an annual percentage rate (APR) of 30% and a minimum payment requirement of 8% of the balance, and you have a balance of $400 on the credit card, you decide to stop charging and pay it off by making the minimum monthly payment each month, here's how it would work:
The minimum monthly payment would be 8% of the balance, which is 0.08 x $400 = $32.
Each month, you would make a payment of $32 towards your credit card balance. However, keep in mind that the interest will continue to accrue on the remaining balance.
Since the APR is 30%, the monthly interest rate would be 30% / 12 = 2.5%.
To calculate the interest charged each month, you multiply the remaining balance by the monthly interest rate. For example, after the first payment, the remaining balance is $400 - $32 = $368. The interest charged for that month would be 2.5% x $368 = $9.20.
Therefore, the total amount paid in the first month would be $32 for the minimum payment plus $9.20 for the interest, totaling $41.20.
Each month, you would continue making the minimum payment, and the interest charged would be based on the remaining balance. The process would continue until the balance is paid off in full.

Step-by-step explanation:
the equation of a line in point- slope form is
y - b = m(x - a)
where m is the slope and (a, b ) a point on the line
here m = - 2 and (a, b ) = (10, - 9 ) , then
y - (- 9) = - 2(x - 10) , that is
y + 9 = - 2(x - 10)
NEED HELP ASAP The equation of line a is: -x + 4y = 32
How do theses equations compare to line a?
y=1/4x + 1
-4x+y=-8
4x+y=-3
y = 1/4x + 1 is parallel to line a
-4x + y = -8 is neither parallel nor perpendicular to line a
4x + y = -3 is perpendicular to line a
Parallel and Perpendicular linesFrom the question, we are to determine how the given equations compare to line a.
From the given information,
Line a is -x + 4y = 32
First, we will determine the slope of line a
To do this, we will compare the equation to the slope-intercept form of a line
The slope-intercept form of a line is
y = mx + b
Where m is the slope
and b is the y-intercept
Writing -x + 4y = 32 in the slope-intercept form
-x + 4y = 32
4y = x + 32
Divide through by
y = 1/4 x + 8
By comparison, the slope of line a is 1/4
NOTE: If two lines are parallel, their slopes will be equal
and
If two lines are perpendicular, their slopes will be the negative reciprocal of each other
Now, we will determine the slopes of each of the lines
For y = 1/4x + 1
By comparing with the slope-intercept form of a line, y = mx + b
The slope of the line is 1/4
Thus, the line is parallel to line a
For -4x+y=-8
Rewrite in the slope-intercept form of a line
-4x + y = -8
y = 4x - 8
By comparing with the slope-intercept form of a line, y = mx + b
The slope of the line is 4
4 is not equal to 1/4 and 4 is not the negative reciprocal of 1/4.
Thus, the line is neither parallel nor perpendicular to line a.
For 4x+y=-3
Rewrite in the slope-intercept form of a line
4x + y = -3
y = -4x - 3
By comparing with the slope-intercept of a line, y = mx + b
The slope of the line is -4
-4 is the negative reciprocal of 1/4.
Thus, the line is perpendicular to line a.

What is the y-intercept of y = x^2 - 3x + 2 by completed square form?
y-intercept(s): (0,−2)
Answer:
2
Step-by-step explanation:
The \(x^{2}\) and x terms are made to follow the sequence:
\([a-b]^{2} =a^{2} -2ab + b^{2}\)
Therefore the \(b^{2}\) term has to be added to complete the \([a -b]^{2}\) sequence, but at the same time the \(b^{2}\) term has to be balanced as it is not originally present in the equation:
\(y = x^{2} - 3x + 2 = [(x)^{2} - 2(x)(\frac{3}{2}) + (\frac{3}{2})^{2}] + 2 - (\frac{3}{2})^{2}\)
\(= [x - \frac{3}{2}]^{2} + 2 - \frac{9}{4}\)
= \([x - \frac{3}{2}]^{2} + \frac{8}{4} - \frac{9}{4}\)
= \([x- \frac{3}{2}]^{2} \frac{+ 8-9}{4}\)
= \([x-\frac{3}{2}]^{2} -\frac{1}{4}\)
y-intercept is the y-value obtained when x = 0 in the equation:
\(= [0 - \frac{3}{2}]^{2} -\frac{1}{4}\)
= \((-\frac{3}{2})^{2} -\frac{1}{4}\)
= \(\frac{9}{4} - \frac{1}{4}\)
= \(\frac{8}{4}\)

Calculate the missing angles a, b, c, and d in the diagram below, giving a reason for each answer
Answer:
see below and attachment
Step-by-step explanation:
a=30°
because, the marked angle of 30° is an alternate interior angle to angle a. Alternate interior angles are congruent, and we know they are congruent because the 2 horizontal lines are parallel.
b=50°
because the marked angle of 50° is a vertical angle to angle b. Vertical angles are congruent because 2 lines that intersect have opposite congruent angles, making them vertical angles to each other.
c=50°
because the marked angle of 50° is a corresponding angle (same side angle) to angle c. These corresponding angles are congruent because the 2 horizontal lines are parallel.
d=100°
because the 3 interior angles of a triangle must add up to 180°. We have 30°, 50°, so the last angle must be 100°. We can also figure this out because the bottom horizontal line is a straight line, meaning the angle is also 180°. We have angle a as 30°, angle c as 50°, so angle d must be 100°.

Mr brainiac has found the Treasure Chest help him to get the code to open the chest the last digit is the half of 18 the sum of the two middle digit is 10 the third of and the fourth digit is the same the first digit is double the second digit what's the answer
A contradiction in the given clues and it is not possible to find a valid code with the given information.
The code to open the treasure chest can be determined using a few simple steps.
Firstly, we know that the last digit is half of 18, which is 9.
This means that the code ends with the number 9.
Next, we are given the information that the sum of the two middle digits is 10.
This tells us that the two middle digits must be 4 and 6, as they add up to 10.
Thirdly, we know that the third and fourth digits are the same.
Since we already know that the last digit is 9, this means that the third digit must also be 9.
Finally, we are told that the first digit is double the second digit.
Since we know that the second digit is 4, we can determine that the first digit must be 8.
Therefore, the code to open the treasure chest is 8469.
Mr Brainiac can now use this code to unlock the chest and discover the treasures inside.
