Answer:
Step-by-step explanation:
assuming that x2 = x², then the equation is y= x²-18
y= x²-18
y-18=x²
[tex]\sqrt{y-18}=\sqrt{x^{2} }[/tex]
[tex]\sqrt{y-18}= x\\[/tex]
so x = [tex]\sqrt{y-18\\}[/tex]

In the diagram below, XY and YZ are tangent to O. What is the measure of XZ?
The measure of arc xz is 106 degrees.
What is Major and Minor Arc ?A small arc is one with a measure of fewer than 180 degrees. A major arc is one with a measure greater than 180 degrees. A semicircle is an arc that divides a circle in half and has a measure of 180 degrees.
An arc is a continuous segment of a circle. There are two sections, one of which is larger than the other. The major arc is the larger one, and the minor arc is the smaller one.
Given:
From diagram, m ∠xz = 254 degrees.
We know that whole circle = 360 degrees
So, measure of arc XZ = 360 - 254
= 106
Hence, the measure of arc xz is 106 degrees.

Fido weighs 26 pounds more than Fifi. Fifi weighs 12 pounds less than Rover. If the sum of their weights is 71, how much does Fifi weigh?
By setting up a system of linear equations using the given relationships and solving for Fifi's weight, we find that Fifi weighs 11 pounds.
Explanation:The question involves solving a system of linear equations to find the weight of Fifi. We are given three pieces of information:
Fido weighs 26 pounds more than Fifi.Fifi weighs 12 pounds less than Rover.The sum of their weights is 71 pounds.Let's denote Fifi's weight as F, Rover's weight as R, and Fido's weight as D. Based on the information provided, we can write the following equations:
D = F + 26F = R - 12F + R + D = 71To find Fifi's weight, we need to substitute the first two equations into the third one:
Substitute D from equation (1) into equation (3): F + R + (F + 26) = 71Substitute R from equation (2) into the new equation: F + (F + 12) + (F + 26) = 71Combine like terms: 3F + 38 = 71Now, solve for F:
3F = 71 - 383F = 33F = 11Therefore, Fifi weighs 11 pounds.

True or False: If a pair of lines is not parallel, it must be perpendicular.
Answer:
False
Step-by-step explanation:
Parallel lines are lines that never intersect. If the line changes slightly, the lines will intersect. This doesn't mean that it's perpendicular
Perpendicular lines are lines that intersect in such a way that the lines form 90 degree angles.
The statement is false. Non-parallel lines are not necessarily perpendicular; they can intersect at any angle other than right angles.
The statement 'If a pair of lines is not parallel, it must be perpendicular' is False. Not all non-parallel lines are perpendicular. Perpendicular lines are a specific case of non-parallel lines where they meet at right angles (90 degrees). Non-parallel lines that are not perpendicular to each other may intersect at any other angle, which could be acute or obtuse but not 90 degrees.
Theorem 10 supports this by stating that 'If two lines cut a third at the same angle, that is, so that corresponding angles are equal, a line can be drawn that is perpendicular to both'. Theorem 14 also relates as it informs 'If a line is perpendicular to two intersecting lines at their intersection, it is perpendicular to all lines of their plane passing through this point'. However, non-parallel lines that do not satisfy these conditions are simply intersecting lines at some angle other than 90 degrees.

The graph shows point F located at (0, 6) and line d given by the equation y = 0.
Drag each coordinate pair into a box to show whether that point is equidistant or not equidistant from point F and line d, or if equal distance cannot be determined.
Answer:
equidistant from point F and line d: (0, 3); (6, 6) and (-6, 6)
not equidistant from point F and line d: (3, 0); (3, 5) and (-2, 2)
Step-by-step explanation:
Point (0, 3)
Distance from point (0, 6) = 3
Distance from line d = 3
Point (6, 6)
Distance from point (0, 6) = 6
Distance from line d = 6
Point (3, 0)
Distance from point (0, 6) = √[(3 - 0)² + (0 - 6)²] = √45
Distance from line d = 0
Point (3, 5)
Distance from point (0, 6) = √[(3 - 0)² + (5 - 6)²] = √10
Distance from line d = 5
Point (-2, 2)
Distance from point (0, 6) = √[(-2 - 0)² + (2 - 6)²] = √20
Distance from line d = 2
Point (-6, 6)
Distance from point (0, 6) = 6
Distance from line d = 6
Find the perimeter of the square
With one side 2 1/2 yards
Answer:
12
Step-by-step explanation:
2.5*4=12
if each side of a square is the same length then yes my answer is correct
Final answer:
To find the perimeter of the square with a side length of [tex]2\frac{1}{2}[/tex] yards, the side length is converted to a decimal and multiplied by 4, resulting in a perimeter of 10 yards.
Explanation:
The student's question is about finding the perimeter of a square when given the length of one side, which is [tex]2\frac{1}{2}[/tex] yards.
Since a square has four equal sides, the perimeter (P) of a square is calculated by multiplying the length of one side (s) by 4, which can be expressed as P = 4s.
In this case, if we convert [tex]2\frac{1}{2}[/tex] yards to a decimal, we get 2.5 yards.
Therefore, the perimeter of the square is 4 × 2.5 yards, which equals 10 yards.

The city aquarium got a new tank for their dolphins. The tank is 16 feet high with a radius of 28 feet. Answer these
questions about the new dolphin tank.
Approximately how much water will it take to fill the tank?
The aquarium needs to purchase a plastic cover for the tank. What should the approximate size of the cover be?
Answer:
I know the answer to the last one. Its D
Step-by-step explanation:
Approximately, the quantity of water it will take to fill this tank is equal to 39,413 cubic feet.
Given the following data:
Radius of cylinder = 28 feet.
Height of cylinder = 16 feet.
How to calculate the volume of this cylinder?Mathematically, the volume of a cylinder is calculated by using this formula:
V = πr²h
Where:
h is the height.r is the radius.Substituting the given parameters into the formula, we have;
V = 3.142 × 28² × 16
V = 39,413.248 ≈ 39,413 cubic feet.
For the cover size, we have:
Area = πr²
Area = 3.142 × 28²
Area = 2,463.328 ≈ 2,463 ft².

Evaluate 5+ (-11) - (-11)
Answer:
5
Step-by-step explanation:
To solve a problem with negatives, we use the following rule.
If it is like
x+(-y), it is equivalent to x-y
If the equation is like
(-x)-(-y), it is equivalent to (-x)+y
So,
5+(-11)=5-11=-6
(-6)-(-11)=(-6)+11=5

Which expression is equivalent to 8g+2+4g-2-2g
Answer:
10g
Step-by-step explanation:
add 8g,4g and -2g to get 10g
add 2 and -2 to receive 0
the simplified expression would be 10g
The equivalent expression for 8g + 2 + 4g - 2 -2g after combining like terms is 10g.
The original expression given is 8g + 2 + 4g - 2 -2g. To find an equivalent expression, we need to combine like terms. We do this by adding or subtracting the coefficients of identical variables and also combining any constant terms.
In this case, we combine the coefficients of g:
8g + 4g - 2g = (8 + 4 - 2)g = 10g.
Next, we combine the constant terms: 2 - 2 = 0. Since adding or subtracting 0 does not change the value, we can ignore this part.
Thus, the equivalent expression is simply 10g.

Jasmine thinks that the images are the same because they are both isosceles triangles. Do you agree with Jasmine why or why not?
Answer:
No, images are not same as their dimensions are different although two sides in each of the two triangles are equal.
Step-by-step explanation:
Given: images of two isosceles triangles.
To check: if images are the same
Solution:
A triangle is a polygon made up of three sides.
An isosceles triangle is a triangle in which two sides are equal. Also, in an isosceles triangle, angles opposite to equal sides are equal.
The given images of two isosceles triangles A and B are not the same as their dimensions are different although two sides in each of the two triangles are equal.
