The correct option is D they will have the same volume.
What is volume?
In math, volume can be defined as the 3-dimensional space enclosed by a boundary or occupied by an object.
They both have the same height, assuming that each coin has same volume, then how can coins in 1 stack have different volume than coins in another stack no matter how you stack them.

calculate the equation of straight line passing through (5,-10) and making equal but opposite intercept.
The equation of the straight line passing through (5,-10) and making equal but opposite intercept is y = -4x + 10.
To solve the problem, we need to know the equation of a straight line
Equation of a straight line in slope intercept formThe equation of a straight line in slope intercept form is given by y = mx + c where
m = slope and c = y- intercept.Given that the straight line passes through the point (5, -10) and making equal but opposite intercept, its intercept is at (-5, 10)
The gradient of the lineWe need to find the gradient, m by making m subject of the formula in y.
So, m = (y - c)/x
With
x = 5, y = -10 and c = 10, we havem = (y - c)/x
m = (-10 - 10)/5
m = -20/5
m = -4
Substiting m and c into y, we have
y = mx + c
y = -4x + 10
So, the equation of the straight line passing through (5,-10) and making equal but opposite intercept is y = -4x + 10.

[tex]\sqrt{25x^{2} } =-2x\sqrt{100x}[/tex]
I assume x is a real variable. Note that √(25x²) is a non-negative number for any real x.
Meanwhile, we observe that for -2x √(100x),
• it's only defined for x ≥ 0, and
• if x ≥ 0, then multiplying √(100x) by -2x makes the overall product non-positive, i.e. -2x √(100x) ≤ 0
In short, this eliminates any non-zero real solution, and we're left with x = 0.
We can arrive at the same result by working with the equation:
√(25x²) + 2x √(100x) = 0
5|x| + 20 x√x = 0
since √(x²) = |x| for all x.
Recall that |x| = x if x ≥ 0, and |x| = -x if x < 0.
• If x ≥ 0, the equation reduces to
5x + 20 x√x = 0
5x (1 + 4√x) = 0
5x = 0 or 1 + 4√x = 0
x = 0 or √x = -1/4
But √x ≥ 0 for x ≥ 0, so we throw out the second solution.
• If x < 0, the equation instead reduces to
-5x + 20 x√x = 0
-5x (1 - 4√x) = 0
-5x = 0 or 1 - 4√x = 0
x = 0 or √x = 1/4
x = 0 or x = 1/16
But we assumed x is negative, so we throw out both choices and get no solution for this case.
Which of the following could be the equation of the function below? on a coordinate plane, a curve crosses the y-axis at y = negative 3. it has a maximum at y = 1 and a minimum at y = negative 3. it goes through 1 cycle at pi. y = negative 2 cosine (4 (x pi)) minus 1 y = 2 cosine (x pi) 1 y = negative 2 cosine (2 (x pi)) minus 1 y = 2 cosine (4 (x pi)) 2

How to find the function which was used to make graph?There are many tools we can use to find the information of the relation which was used to form the graph.
A graph contains data of which input maps to which output.
Analysis of this leads to the relations which were used to make it.
For example, if the graph of a function is rising upwards after a certain value of x, then the function must be having increasingly output for inputs greater than that value of x.
If we know that the function crosses x axis at some point, then for some polynomial functions, we have those as roots of the polynomial.
What are some properties of a cosine function?Suppose that we've got:
[tex]f(x) = a \cos (bx - c) + d[/tex]
Then, this function has:
Period = [tex]\dfrac{2\pi}{b}[/tex]Phase shift = [tex]\dfrac{c}{b}[/tex]Maximum value: a + dMinimum value: -a + dFor this case, we're given that:
The function crosses y-axis at y = -3The maximum value of the function is y = 1The minimum value of the funciton is y = -3It goes through 1 cycle at pi.All the options are of cosine function, so let the function be:
[tex]f(x) = a \cos (bx - c) + d[/tex]
Then, as per the given data about max and min. values, we get:
d+a=1
d-a = -3
Adding both equations,
2d = -2 => d = -1
Thus, -1+a = 1, and therefore a = 2
Since it goes through 1 cycle at pi, so its period = π
Thus, we get:
[tex]Period = \pi = 2\pi/b\\\\or\\\\b = 2[/tex]
Now since there is only third option which has d= -1, and b =2 so assuming at least one option was true, we get the needed function as described by the option C.
Thus, the equation of the function which is graphed on the right is specified by: Option C: y = -2cos(2(x + π)) -1

Answer:
π/4 radiansπ/4 radiansStep-by-step explanation:
The relationship between angle measures in degrees and angle measures in radians does not depend on the radius of the circle. It is always ...
180° = π radians
__
Then an angle of 45° will be ...
45° × (π radians)/(180°) = π/4 radians
This value is the same for a radius of 5 cm or of 1 cm.
_____
Additional comment
We have made the conversion from degrees to radians using a conversion factor that has radians in the numerator and degrees in the denominator. When we mutiply by this factor, the units of degrees cancel, leaving units of radians. We use a conversion factor that has the same angle value in numerator and denominator, so it doesn't change the angle we're multiplying. It only changes the units.
The same relation can be expressed as a proportion:
(π radians)/180° = (x radians)/(45°)
When you multiply this equation by 45° on both sides, you get the equation we used above.
A store offers a 30% discount on a coat that originally sold for $120. The coat still does not sell, so the store offers another 30% o the sale price. What is the difference between this price and the price of the coat had it been marked down 60% all at once?A. $5. 80 B. $7. 40C. C. $10. 8 D. No difference; the resulting prices are the same
Answer:
C. $10.80
Step-by-step explanation:
Lets solve for first 30% discount
120/ 10 =12 (divided by 10 to get 10% of the whole)
12= 10% of 120
36= 30 % of 120 (multiplied by 3 to get 30%)
120-36= 84
Lets solve for second 30% discount
84/10 =8.4 (divided by 10 to get 10% of the whole)
8.4= 10% of 84
25.2 = 30% of 84 (multiplied by 3 to get 30%)
84-25.2=58.80 (subtracted the discount from the total to get the sale price)
Let's solve for what it would cost had they done 60% to begin with
120/10 = 12 (divided by 10 to get 10% of the whole)
12= 10% of 120
72= 60% of 120 (multiplied by 6 to get 60%)
120-72 = 48 (subtracted the discount from the total to get the sale price)
Let's solve for the difference between the two
58.80-48= 10.80
