Logan just became a personal trainer and is finalizing his pricing plans. One plan is to charge $18 for the initial consultation and then $88 per session. Another plan is to charge $39 for the consultation and $87 per session. Logan realizes that the two plans have the same cost for a certain number of sessions. What is that cost? How many sessions is that?
Answer: The 2 Plan will have same cost of $2149 after 64 sessions.
Let the Two plan be Plan A and Plan B.
Also let the number of session be
According to given detail
Plan A =
Plan B =
We need to find the value of when both are equal.
Plan A = Plan B

X = 14
Hope this helps!
Step-by-step explanation:
The small red square means the angle is 90°.
( 2x + 22 ) + ( 3x - 2 ) = 90°
2x + 22 + 3x - 2 = 90
( 2x + 3x ) + ( 22 - 2 ) = 90
5x + 20 = 90
5x + 20 - 20 = 90 - 20
5x = 70
x = 14
Answer: x = 14
Step-by-step explanation:
When you have a right angle, they add up to 90 degrees
So you add up the two angles that you have that equal a total of 90 degrees
2x+22 + 3x-2 = 90
5x+20 = 90
5x = 70
x = 14

what is the notation used for a vector pointing into the page? what about a vector pointing out of the page?
The notation used for a vector pointing into the point is X.
A quantity with a magnitude and direction is called a vector. A vector quantity will be identified in these annotations by a bold letter (such as the electric field vector E). Vectors appear graphically as straight arrows. The magnitude of the vector is commonly represented by the length of the arrow, and both the arrow and the vector point in the same general direction.
Arrows are drawn on the page to represent vectors in the page's plane. Typically, circles with an X engraved on them are used to represent vectors that enter the screen's plane. A vector that deviates from the screen's plane is often represented by circles with dots in the center.

What is congruent polygons ?
A polygon is said to be congruent if it has the same shape as the polygon it is compared to, as well as the identical side lengths and interior angles. In order to meet the condition, congruent shapes must all have the same kind of shape. Because they are different shapes, a rectangle and a pentagon cannot be congruent.
Two squares or two hexagons can be considered congruent polygons since they both have equal-length sides and angles. However, it's crucial to keep in mind that the length of the sides must also be equal. A square is not congruent if it is larger than another square.

As stated in the preceding statement the point R is collinear with points A and B.
What is a collinear?An axis is a term used to describe a line upon whatever points are located, particularly if that line is connected to a triangle or other geometric shape. Since two factors determine a line, two points become trivially collinear.
How are collinear points discovered?Two lines may coincide if they have a same point and have the same slope. To put it another way, if A, B, as well as C are three points there in XY plane, they will all lie on a line, or three points will be collinear, but only if AB's slope and BC's slope are both equal.

Vertical asymptote of the function is, None.
What is domain and range?
The range of values that we are permitted to enter into our function is known as the domain of a function. The x values for a function like f make up this set (x).
A function's range is the collection of values it can take as input. After we enter an x value, the function outputs this sequence of values.
First to find the domain of the function,
Since, all input values shown on the x-axis make up a graph's domain.
We can see that values of x values are from 0 to ∞.
Hence, the domain is (0, ∞).
Now to find the range.
Since, the y-axis on a graph represents the possible output values, or range.
The y - axis having the values from -∞ to ∞.
Hence, the range of the function is, (-∞, ∞).
x - intercept is the point where function crosses the x - axis.
Here function crosses x - axis at (1, 0).
Hence, the x - intercept is (1, 0).
A graph's vertical asymptote is the vertical line at x = a where the graph trends toward positive or negative infinity as the inputs go closer to a.
So, the vertical asymptote is x = 0.

Find the equation of a line parallel to 5x+3y=−21 that passes through the point (-9,-3)
To find: Equation of line parallel to 5x + 3y = -21 and passes through the point (-9, -3)
Solving the given 5x + 3y = -21 for 3y yields 3y = -5x - 21.
Dividing all three terms by 3, we get:
y = (-5/3)x - 7, indicating that the given line has slope -5/3.
The slope of a line perpendicular to this y = (-5/3)x - 7 is 3/5, the negative reciprocal of -5/3.
Start with y = mx + b
Substitute -3 for y, -9 for x, and 3/5 for m
We get,
-3 = (3/5) (-9) + b
∴ b = 5/9
Thus, the equation is y = (3/5)x + 5/9 is the required equation of a line parallel to 5x+3y=−21 that passes through the point (-9,-3)

time needed:
Considering an exponential function, it is found that:
a) The half-life of the element is of 39.63 days.
b) The time needed is of 51.82 days.
What is an exponential function?A decaying exponential function is modeled by the equation presented as follows:
[tex]A(t) = A(0)(1 - r)^t[/tex]
In which the variables of the equation are:
A(0) is the initial value.r is the decay rate, as a decimal.In this problem, the parameters are given as follows, from the text:
A(0) = 120, A(11) = 99.
Hence the decay rate r is obtained as follows:
[tex]A(t) = A(0)(1 - r)^t[/tex]
[tex]120 = 99(1 - r)^{11}[/tex]
[tex](1 - r)^{11} = \frac{99}{120}[/tex]
[tex]1 - r = \sqrt[11]{\frac{99}{120}}[/tex]
[tex]1 - r = \left(\frac{99}{120}\right)^{\frac{1}{11}}[/tex]
1 - r = 0.98266367982
Hence the equation is:
[tex]A(t) = A(0)(0.98266367982)^t[/tex]
The half-life is the value of t for which:
A(t) = 0.5A(0).
Hence:
[tex]A(t) = A(0)(0.98266367982)^t[/tex]
[tex]0.5A(0) = A(0)(0.98266367982)^t[/tex]
[tex](0.98266367982)^t = 0.5[/tex]

[tex]t = \frac{\log{0.5}}{\log{(0.98266367982)}}[/tex]
t = 39.63 days.
For item b, the time is obtained as follows:
[tex]A(t) = 99(0.98266367982)^t[/tex]

When a cylinder "leans over," that is when its sides are not parallel to its bases, then the cylinder is said to be an oblique cylinder. The bases (ends) of an oblique cylinder stay parallel to one another, while the sides tilt outward at an angle that isn't quite 90°.
An oblique cylinder will have the same volume as a right cylinder with the same radius and height. As long as the radius and height are the same, the volume does not vary, but the height must equal the perpendicular height.

According to a report for veterinarians in the united states, 36. 5 percent of households in the united states own dogs and 30. 4 percent of households in the united states own cats. If one household in the united states is selected at random, what is the probability that the selected household will own a dog or a cat?.
The probability of the selected household will own a dog or a cat can't be determined because there is not enough information to determine the probability
How to calculate probility?Probability is counted by dividing the event number with the total number of outcomes. In this case, the probability of the selected household will own a dog or a cat will have a formula like this:
P(A ∨ B)=P(A)+P(B)+P(A ∧ B)
Annotation:
P(A ∨ B) = probability own a dog or a cat
P(A) = probability own a dog
