−36+x<8 whats is the x
Answer:
Therefore, the possible values of x are all numbers less than 8.
Step-by-step explanation:
To find the value of x, we need to isolate the variable on one side of the inequality.
To do this, we can subtract 36 from both sides of the inequality to get -36 + x < 8 - 36.
This simplifies to -36 + x < -28.
Next, we can add 36 to both sides to get x < -28 + 36, which simplifies to x < 8.
Therefore, the possible values of x are all numbers less than 8.

Find the coordinates of the circumcenter of the triangle with the given vertices.
H(-10,7), J(-6,3), K(-2,3)
find the circumvented
The coordinates of the circumcenter of the triangle with the vertices H(-10, 7), J(-6, 3) and K(-2, 3) is (-4, 9).
What is a triangle?A triangle is a geometric figure with three edges, three angles and three vertices. It is a basic figure in geometry.
The sum of the angles of a triangle is always 180°
The given points are H(-10, 7), J(-6, 3) and K(-2, 3)
Since, Circumcenter of triangle is equidistant from vertices,
Therefore, H(-10, 7), J(-6, 3) and K(-2, 3) are equidistant from circumcenter O,
Let the coordinate of O be (x,y).
OH = OJ
(x + 10)² + (y - 7)² = (x + 6)² + (y - 3)²
x² + 100 + 20x + y² + 49 - 14y = x² + 36 + 12x + y² + 9 -6y
8x - 8y + 104 = 0
x - y + 13 = 0 (1)
Also, OH = OK
(x + 10)² + (y - 7)² = (x + 2)² + (y - 3)²
x² + 100 + 20x + y² + 49 - 14y = x² + 4 + 4x + y² + 9 - 6y
16x - 8y + 136 = 0
2x - y + 17 = 0 (2)
By solving equation (1) and (2),
x = -4
y = 9
The coordinate of the circumcenter is (-4, 9).
Hence, this is the required answer.

Find all solutions of the equation
|x^2 - 30x - 1| + |x^2 - 30x + 29| = 30
Answer:
[15-√226, 1] ∪ [29, 15+√226]
Step-by-step explanation:
You want all solutions to |x^2 - 30x - 1| + |x^2 - 30x + 29| = 30.
DomainsThe equation resolves to a piecewise equation whose domains are delimited by the points where the absolute value arguments are zero.
Left argumentThe argument of the left absolute value function will be zero where ...
x^2 - 30x - 1 = 0
x = (-(-30) ±√((-30)² -4(1)(-1)))/(2(1) = 15 ± √226 ≈ {-0.0332964, 30.0332964}
Right argumentThe argument of the right absolute value function will be zero where ...
x^2 -30x +29 = 0
(x -29)(x -1) = 0
x = {1, 29}
Piece-wise equations-∞ < x < 15-√226In this domain, both absolute value arguments are positive, so the equation is ...

-(x^2 -30x -1) +(x^2 -30x +29) = 30
30 = 30
All values of x in this domain (15-√226 ≤ x ≤ 1) are in the solution set.

Compare the investment below to an investment of the same principal at the same rate compounded annually.
principal: $6,000, annual interest: 6%, interest periods: 6, number of years: 18
The investment compounded annually has a higher final value than the investment you described because the annual compound interest rate is higher.
What is compound interest?
Compound interest is a type of interest that is calculated on the initial principal of an investment as well as any accumulated interest. In other words, compound interest is interest that is earned on both the original principal and on the accumulated interest from previous periods.
To compare the investment you described to an investment of the same principal at the same rate compounded annually, we need to calculate the final value of each investment after 18 years.
For the investment you described, the final value can be calculated using the formula:
FV = P(1 + r/n)^(nt)
Where FV is the final value, P is the principal, r is the annual interest rate, n is the number of interest periods per year, and t is the number of years.
Plugging in the values given in the problem, we get:
FV = $6,000(1 + 0.06/6)^(6*18) = $6,000(1.01)^108 = $12,688.80
For the investment compounded annually, the final value can be calculated using the same formula, but with n = 1:
FV = $6,000(1 + 0.06/1)^(1*18) = $6,000(1.06)^18 = $15,848.75
Hence, the investment compounded annually has a higher final value than the investment you described because the annual compound interest rate is higher. The difference in final value between the two investments is $15,848.75 - $12,688.80 = $3,159.95.

The following is a graph of the function f(x) = 2^x. The graph was transformation to h(x) = 1/7×2^x. How does this change the graph?
Answer:
The graph of h(x) = 1/7×2^x will be shifted to the left and compressed compared to the graph of f(x). The y-intercept of h(x) will be 1/7, whereas the y-intercept of f(x) is 1. The graph of h(x) will also have a much smaller range than the graph of f(x).
Step-by-step explanation:
The equation of a graph is given by y=f(x). After transformation, the equation changes to y=h(x).
h(x) = 1/7×2^x
h(x) = 1/7 × (2^x)
h(x) = 1/7 * 2^x
h(x) = (1/7)2^x
=> y = (1/7)2^x
=> y = 1/7 (2^x)
Therefore, the graph of h(x) = 1/7×2^x will be shifted to the left and compressed compared to the graph of f(x). The y-intercept of h(x) will be 1/7, whereas the y-intercept of f(x) is 1. The graph of h(x) will also have a much smaller range than the graph of f(x).
Answer:
The graph of h(x) = 1/7×2^x would be the same as the graph of f(x) = 2^x, but it would be vertically scaled down by a factor of 1/7. This means that all the points on the graph of h(x) would have the same x-coordinates as the corresponding points on the graph of f(x), but their y-coordinates would be 1/7 times smaller. For example, the point (1,2) on the graph of f(x) would be located at (1,1/7) on the graph of h(x).

A) Write and solve a linear equation to find the equipment rental fee.
B) How much would it cost for 6 hours of training?
(High school)
a) The linear function used to find the equipment rental fee is of: y = 9x + 20.
b) The cost for 6 hours of training is of: $74.
How to define the linear function?The linear function is defined considering it's slope-intercept format, given as follows:
y = mx + b.
The coefficients of the function are given as follows:
m is the slope, representing the cost per hour.b is the intercept, representing the flat fee.A soccer training camp charges $9.50 per hour for training, hence the slope is of:
m = 9.
The total fee for 12 hours of training was $128, hence the intercept b is obtained as follows:
128 = 9(12) + b
b = 128 - 108
b = 20.
Hence the function is defined as follows:
y = 9x + 20.
The cost for six hours of training is obtained as follows:
y = 9(6) + 20 = $54.

Step-by-step explanation:
latus rectum is equal to hald of its mojor axis and which passes through the point (√6,1)
Answer:
The latus rectum of an ellipse is a line segment that is perpendicular to the major axis of the ellipse and passes through one of its foci. If the ellipse has a major axis of length 2a, then the latus rectum will have a length of a. Therefore, if the latus rectum is equal to half of the major axis, then the major axis must have a length of 2a, and the latus rectum will have a length of a.
The point (√6, 1) can be the end point of the latus rectum if it lies on the ellipse. To determine if this is the case, you can substitute the coordinates of the point into the standard equation of an ellipse. If the point satisfies the equation, then it lies on the ellipse and can be the end point of the latus rectum.
The standard equation of an ellipse with major axis of length 2a and minor axis of length 2b is:
(x - h)^2 / a^2 + (y - k)^2 / b^2 = 1
Where (h, k) is the center of the ellipse. In this case, we don't know the values of a, b, h, and k, so we can't determine if the point (√6, 1) lies on the ellipse. However, we can use the fact that the latus rectum has a length of a to find the center of the ellipse.
Since the latus rectum is perpendicular to the major axis and passes through the focus, it must also pass through the center of the ellipse. Therefore, the midpoint of the line segment defined by the coordinates (√6, 1) and the center of the ellipse must be the center of the ellipse. The coordinates of the center can be found by taking the average of the x-coordinates and the average of the y-coordinates. In this case, the center of the ellipse will have coordinates:
(x, y) = ((√6 + h) / 2, (1 + k) / 2)
Once you know the center of the ellipse, you can use the standard equation of an ellipse to find the values of a, b, h, and k. Once you have those values, you can determine if the point (√6, 1) lies on the ellipse and can be the end point of the latus rectum.

We only need to multiply by 10 to determine the length because we know the length is 10 meters longer than our width is 38.75 meters for L.
What is the explanation?The formula for a rectangle's perimeter is
2w + 2L = P where w stands for width and l for length.
The length is 10 meters longer than the breadth, according to this dilemma. So:
L = 10 + w
In our perimeter equation, we may replace L with 10 + w and also 80 in place of P, our perimeter, to solve:
2W + 2(10 + W) = 100
2W + 20 + 2W = 100
4W + 20 = 100
-25. -20
