Step-by-step explanation:
the length and the width of a rectangle create a right-angled triangle, with the diagonal being the Hypotenuse of that triangle (the baseline, opposite of the 90° angle).
so, we can use Pythagoras
c² = a² + b²
with c being the Hypotenuse.
so, we have here
diagonal² = 40² + 9² = 1600 + 81 = 1681
diagonal = sqrt(1681) = 41 in
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)
Therefore, the weight loss after 16 days will be 17.6 pounds and after 6 weeks will be 46.2.

Let f(x) = 6x^2 - 4x + 2. Find a constant c between 1 and 9 such that the average value of the function f(x) on the interval (1,9] is equal to fc).
A. 4.8735
B. 5.5402
C. 5.5721
D. -4.8735
E. 164
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]
Thus, 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.

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

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.

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](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]

We know that...

So that means

And with that info, 5 1/6 becomes

_______________________________________________________
Solve by improper fractions ➗
We know from the last problem that...
[tex]5\frac{1}{6} = 5 + \frac{1}{6}[/tex]
Converting 5 as a whole number to a fraction, it becomes
[tex]5 = \frac{5}{1}[/tex]
Now it becomes...
[tex]\frac{5}{1} + \frac{1}{6}[/tex]
Since the fractions will not change, first find the whole, then multiply your improper fraction by the whole, and add the part
[tex]\frac{6}{6}\\\\ = (\frac{5}{1} * \frac{6}{6} ) + \frac{1}{6}[/tex]
Converting to improper fraction

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

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
