The difference between the depths in February and July is 19 feet.
To find the difference between the depths in February and July, we need to subtract the depth in February from the depth in July.
The depth in February is given as |−6|, which is 6 feet, and the depth in July is given as |−25|, which is 25 feet.
Difference = Depth in July - Depth in February
Difference = 25 feet - 6 feet
Difference = 19 feet
Therefore, the difference between the depths in February and July is 19 feet.In February, the depth of the lake is given as |−6|, which represents the absolute value of -6. The absolute value of a number disregards its sign, so |−6| is equal to 6 feet.
In July, the depth of the lake is given as |−25|, which represents the absolute value of -25. Again, disregarding the sign, |−25| is equal to 25 feet.
To find the difference between the depths in February and July, we subtract the depth in February from the depth in July:
Difference = Depth in July - Depth in February
Difference = 25 feet - 6 feet
Difference = 19 feet
Therefore, the difference between the depths in February and July is 19 feet. This means that the lake experienced a change of 19 feet in depth between those two time points.

Which expression simplifies to 2√/15?
The simplification of the number 2√15 is 7.74.
What is defined as taking square root?Squaring a number would be the inverse operation of square rooting it.
The square of a number is really the value obtained by multiplying the number by itself, whereas the square root of such a number is obtained by locating a number that, when squared, yields the original number. If 'a' has been the square root of 'b,' then a × a = b.A number's square root is the value of power 1/2 of such a number. In all the other phrases, it is the number for whom product yields the original number on its own. It is represented by the symbol '√ '. The square root sign is known as a radical, and the number beneath it is known as a radicand.The given expression is;
= 2√15
For finding the value of √15; use long division method.
√15 = 3.87
Put the value;
= 2 × 3.87
= 7.74.
Thus, the value of the expression is found as 7.74.

Suppose that people who study very hard for the bar exam have an odds of 1.22 of passing the bar exam. what is the probability someone who studies very hard for the bar passe?
0.45 is the probability someone who studies very hard for the bar passe.
What is probability?
The probability is the measure of the likelihood of an event to happen. It measures the certainty of the event. The formula for probability is given by; P(E) = Number of Favourable Outcomes/Number of total outcomes.Odds of passing = 1.22 = p ( passing)/ P(not passing)
P(Pass)/P( fail) = 1.22
p (pass) = 1.22 p (fail)
P(pass) + P(fail) = 1
1.22 p (fail) + p(fail) = 1
2.22 p(fail) = 1
P (fail) = 0.4505 ≅ 0.45

What is Trig Identities?Trig identities come in handy when we need to express one trig function in terms of another. The most famous trig identity is derived straight from the Pythagorean Theorem:
sin² t + cos² t = 1
According to the given data:For an angle t in Quadrant IV, we know sin t is positive.
From the trig identity sin² t + cos² t = 1
we can also write as:
sin t + cos t:
Now,
sin² t + cos² t = 1
sin² t = 1 - cos² t
sin t = ±√( 1 - cos² t)
As noted above,
sin t is positive for t in the Quadrant IV, and so we have
sin t = √( 1 - cos² t)
We know that

software. Suppose a graph of the curve showing the number of sales over time can be
modeled with a parabola and that the company plans on the "life span" of its product to be
6 months, with maximum sales reaching 1.5 million units. Write an equation that models
this situation.
The equation of the parabola that models the given situation is y=-1/6 (x-3)^2 +1.5.
Define parabola and its types.
A parabola is a roughly U-shaped mirror-symmetrical plane curve. It corresponds to a number of seemingly unrelated mathematical descriptions that all define the same curves.
To represent a parabola algebraically in the coordinate plane, the standard equation of a parabola is used. The general equation of the parabola is given by [tex]$\mathrm{y}=a(x-h)^2+\mathrm{k}$[/tex]or [tex]$\mathrm{x}=a(y-k)^2+\mathrm{h}$[/tex], where [tex]$(\mathrm{h}, \mathrm{k})$[/tex] denotes the vertex. A regular parabola's standard equation is y^2= 4ax
Now, the equation of parabola for the given situation is calculated as:
y=a(x-3)^2 +1.5
Now, put the value of x=0 and y=0.
0=a(0-3)^2+1.5
0=9 a+1.5
-9 a=1.5
a=-1.5 / 9
a=-1 / 6

How to determine the point?The coordinates are given as:

m : n = 1 : 4
The location of the point is then calculated as:
P = 1/5 * (mx2 + nx1, my2 + ny1)

P = 1/5 * (1 * 1 + 4 * -3, 1 * 1 + 4 * -2)
Evaluate
P = 1/5 * (-11, -7)

Triangle FUN has vertices with coordinates F(-6, 4), U(2, 2), and N(-2, -8). Dilate using the Scale factor of 2. What are the coordinates of the dilated image F’U’N’?
explain
Answer:
F ' (-12, 8)
U ' (4, 4)
N ' (-4, -16)
===================================================
Explanation:
I'm assuming the center of dilation is the origin.
Multiply each coordinate by the scale factor 2.
For point F, the x coordinate goes from -6 to 2*(-6) = -12. The y coordinate goes from 4 to 2*4 = 8
So F(-6,4) moves to F ' (-12, 8)
Use this idea for the other points.
If the center of dilation wasn't the origin, then we can't use this shortcut (not until translating the center to the origin).

The likelihood of an occasion is a number somewhere in the range of 0 and 1, where, generally talking, 0 shows difficulty of the occasion and 1 demonstrates conviction. The higher the likelihood of an occasion, the almost certain it is that the occasion will happen. A straightforward model is the throwing of a fair coin. Since the coin is fair, the two results are both similarly likely; the likelihood of "heads" approaches the likelihood of "tails"; and since no different results are conceivable, the likelihood of by the same token "heads" or "tails" is 1/2.

a rectangular prism w a square base with side length(x) and a height of length(y) has a surface area of 100 square feet
The the rectangular solid with maximum volume for given surface area is, in fact, a cube with side 4.5.
Which formula represents the volume of a rectangular prism?
The formula for the volume of a prism is V=Bh , where B is the base area and h is the height. The base of the prism is a rectangle. The length of the rectangle is 9 cm and the width is 7 cm. The area A of a rectangle with length l and width w is A=lw .Let x = the side of the square base and y = height
Let V = volume = x2y
The surface area = 2x2 + 4xy = 121.5
Solve the surface area equation for y = (121.5 - 2x2)/4x and substitute this into the volume equation
V = x2(121.5 - 2x2)/4x = x(121.5 - 2x2)/4
the derivative of V with respect to x = (x/4)(-2x) + (1/4)(121.5 - 2x2) = 0 at the maximum
(1/4)(-4x2 + 121.5 - 2x2) = 0'
6x2 = 121.5
x2 = 20.25
x = 4.5
y = (121.5 - 40.5)/(4 * 4.5) =81/18 = 4.5
