A grounds crew is marking out a circular logo at the center of a football field. The logo will
have a circumference of 141.3 feet. What will be the diameter length of the logo in yards?
Answer:
circumference of a circle formula is C=2*pi*r
Step-by-step explanation:
then
141.3 = 2*pi * r
solve for r
141.3/ (2*pi) = r
22.48859 feet
diameter is 2*r
2*22.48859= 44.9771 feet
divide by 3 because there are 3 feet in one yard
44.9771/3= 14.99239 yds.
it doesn't say to round off, but I would call this 15 yds.
Diameter is 15 yards ± .008 yds That's just about 1/4 of an inch

Your brother is 1/3 your age. Your sister is 4 years older than your brother. Your sister is 9 years old. Write and solve an equation to find your age a.
what is the equation helppppp
Answer:
Your age(a) is 15 in this case.
If your brother is 1/3 of your age, that means multiply your brother's age by 3
Your sister is 9, and is 4 years older than your brother. In that case, we now know that your brother is 5
With that information, we can put this into a valid equation.
------------------------------------------------------------------------------------------------------------
turn 1/3 into a flipped fraction, 3/1 which is equal to 3
your brother's age is 5, so the first value would be 5
5 times 3 is 15, so that means a is 15

x^2 + y^2 +2x+6y=26
what is the center
what is the radius
please show calculations/steps
Answer:
centre = (- 1, - 3 ) , radius = 6
Step-by-step explanation:
the equation of a circle in standard form is
(x - h)² + (y - k)² = r²
where (h, k ) are the coordinates of the centre and r is the radius
given
x² + y² + 2x + 6y = 26 ( collect x and y terms )
x² + 2x + y² + 6y = 26
using the method of completing the square
add ( half the coefficient of the x/ y terms )² to both sides
x² + 2(1)x + 1 + y² + 2(3)y + 9 = 26 + 1 + 9
(x + 1)² + (y + 3)² = 36 ← in standard form
with centre = (- 1, - 3 ) and r = [tex]\sqrt{36}[/tex] = 6
[tex](x {}^{2} + 2x + 1) - 1 = (x + 1) {}^{2} - 1[/tex]
[tex](y {}^{2} + 6y + 9) - 9 = (y + 3) {}^{2} - 9[/tex]
[tex](x + 1) {}^{2} - 1 + (y + 3) {}^{2} - 9 = 26[/tex]
[tex](x + 1) {}^{2} + (y + 3) {}^{2} = 26 + 10[/tex]
[tex](x + 1) {}^{2} + (y + 3) {}^{2} = 36[/tex]
General form:[tex](x - a) {}^{2} + (y - b) {}^{2} = r {}^{2} [/tex]
Center coordinates: I ( a , b ) I ( -1 , -3 )Radius:[tex]r {}^{2} = 36[/tex]

Verify that the function satisfies the hypotheses of the Mean Value Theorem on the given interval Then find all numbers c that satisfy the conclusion of the Mean Value Theorem: f(x) = 1/x on [1,3]
f(x) = 1/x and its derivative f '(x) = -1/x² are discontinuous only at x = 0; everywhere else it is defined and behaves nicely in the sense that f is
• continuous on the closed interval [1, 3], and
• differentiable on the open interval (1, 3)
and the MVT holds.
The theorem says there is some real number c between 1 and 3 such that
[tex]f'(c) = \dfrac{f(3) - f(1)}{3 - 1}[/tex]
Solve for this c :
[tex]-\dfrac1{c^2} = \dfrac{\frac13-\frac11}{3 - 1} \implies c^2 = 3 \implies \boxed{c = \sqrt3}[/tex]

To find :-
The base of a triangle glass window
Given :-
Height of the window = 48 inches
Area of glass = Area of traingle = 1728 square inches
There is a formula to find area of triangle
[tex]area = \frac{1}{2} \times base \times height \\ 1728 = \frac{1}{2} \times base \times 48 \\ 1728 = 24 \times base \\ \frac{1728}{24} = base \\ 72 \: inches = base[/tex]
Result :-
The base of triangle window of beach house is 72 inches.

The value of constant c between 1 and 9 such that the average value of the function f(x) on the interval [1,9] is equal to is 5.
What is mean value theorem?Mean value theorem is the theorem which is used to find the behavior of a function.
The function given as,
[tex]f(x) = 6x^2 - 4x + 2[/tex]
The value of function at 0,
[tex]f(0) = 6(0)^2 - 4(0) + 2\\f(0)=2[/tex]
Differentiate the given equation,
[tex]f(x)' = 6\times2x - 4\times1 + 0\\f(x)' = 12x - 4\\f(x)' = 12x -4[/tex]
If the constant c between 1 and 9 such that the average value of the function f(x) on the interval (1,9], then,
[tex]f(c)'=12c-4[/tex]
Using Lagrange's mean value theorem,
[tex]f(c)'=\dfrac{f(9)-f(1)}{9-1}\\12c-4=\dfrac{452-4}{9-1}\\12c=54+4\\c=\dfrac{60}{12}\\c=5[/tex]

Answer:
5.5402
Step-by-step explanation:
First you need to find the average value of the function, you can use a calculator to do that, which you will find is 164.
The questions asks you to find a number between 1 and 9 so that f(c) (which is just f(x)) equals the average value of the function.
Since you already know the average value (164), you can set the equation equal to 164 and solve for x, which should give you 5.5402.
If you want more information: the function equals the average value, which is 164=6x^2-4x+2, is the equation you want to set up and solve for x.
You may get two answers and I can't explain why because I don't understand it that well, just use the one that is in the 1 to 9 range.
The second answer should be negative which is out of the 1 to 9 range, which leaves you with the other number that rounds up to 5.5402

54. Find [tex]y^{\prime}[/tex] if [tex]x^y=y^x\text{.}[/tex]
Step-by-step explanation:
Take the natural log of both sides:
[tex]ln ({x}^{y} ) = ln ({y}^{x} )[/tex]
Logarithm rules allow you to bring down the exponents:
[tex]yln(x) = xln(y)[/tex]
Now differentiate. We will have to implicitly differentiate 'y' since it is a function of 'x'. Both sides require the product rule:
[tex] \frac{dy}{dx} ln(x) + \frac{y}{x} = ln(y) + \frac{x}{y} \frac{dy}{dx} [/tex]
Isolate the terms that have y' since that is what we want:
[tex] \frac{dy}{dx} ln(x) - \frac{x}{y} \frac{dy}{dx}= ln(y) - \frac{y}{x} [/tex]
Factor out y' to get:
[tex] \frac{dy}{dx}( ln(x) - \frac{x}{y})= ln(y) - \frac{y}{x} [/tex]
Therefore:
[tex] \frac{dy}{dx} = \frac{ln(y) - \frac{y}{x} }{ln(x) - \frac{x}{y} } [/tex]

During a 6-week weight-loss regimen, Tony lost weight at a rate of 1.1 pounds per day. How much did he lose after 16 days? After weeks?
Answer:
After 16 days: 17.6 pounds
After 6 weeks: 46.2
Step-by-step explanation:
1.1 x 16 = 17.60
42 x 1.1 = 46.2 (6 weeks x 7 days a week = 42)
The weight loss after 16 days will be 17.6 pounds and after 6 weeks will be 46.2.
What is an expression?The mathematical expression combines numerical variables and operations denoted by addition, subtraction, multiplication, and division signs.
Mathematical symbols can be used to represent numbers (constants), variables, operations, functions, brackets, punctuation, and grouping. They can also denote the logical syntax's operation order and other properties.
Given that during a 6-week weight-loss regimen, Tony lost weight at a rate of 1.1 pounds per day.
The weight loss after 16 days will be calculated as,
1.1 x 16 = 17.60 pounds
The weight loss after 6 weeks will be calculated as,
42 x 1.1 = 46.2 (6 weeks x 7 days a week = 42)

A polygon is translated and then stretched vertically. Which statement is correct?
A.
The translation does not preserve side lengths and angles, but the vertical stretch preserves side lengths and angles of the preimage.
B.
Neither the translation nor the vertical stretch preserves side lengths and angles of the preimage.
C.
The translation preserves side lengths and angles, but the vertical stretch does not preserve side lengths and angles of the preimage.
D.
Both the translation and the vertical stretch preserve side lengths and angles of the preimage.
C: The translation preserves side lengths and angles, but the vertical stretch does not preserve side lengths and angles of the preimage.
How to explain translation of a polygon?When we talk about the concept of translation in transformations, it means that the side lengths remain the same. This means the object is just moved from one place to another and the lengths are preserved.
However, when we stretch the polygon, it means we are increasing or decreasing at least one side length.
Thus, we can conclude that The translation preserves side lengths and angles, but the vertical stretch does not preserve side lengths and angles of the preimage.
