Answer:
B. (x, y) ⇒ (x, -y)
Step-by-step explanation:
When a point is reflected over the x-axis, it is moved along a vertical line to the same distance on the other side of the x-axis.
The x-coordinate of a point identifies its distance from the y-axis--the vertical line it is on. The y-coordinate identifies its distance from the x-axis. Changing the sign of the y-coordinate moves the point to the same distance on the other side of the x-axis--reflecting it over the x-axis.
__
The given points ABC and A'B'C' all match the pattern ...
(x, y) ⇒ (x, -y)
A(-1, 7) ⇒ A'(-1, -7)
B(6, 5) ⇒ B'(6, -5)
C(-2, 2) ⇒ C'(-2, -2)
so the image points represent a reflection over the x-axis of the original points.

The solution is, D. They grow heavy and fall to the ground., is part of the process in the formation of hail pellets.
What is hail pellets?Graupel is also called snow pellets or soft hail, as the graupel particles are particularly fragile and generally disintegrate when handled. Sleet are small ice particles that form from the freezing of liquid water drops, such as raindrops.
here we have,
Hail is a form of precipitation when droplets of water freeze together in the cold upper reaches of the thunderstorms.
Thee chunks of that range from 5 to 15 cm can be round and jagged. Hail fall on the ground in a solid form they are often associated with tornadoes and certain parts of the world receive more hail than other parts do.
These frozen droplets of water when fall from the clouds get uplifted by wind and that adds another layer to them. The freezing occurs below the zero degrees at an altitude of 11,000 feet.
Mostly found in North America Nebraska, colorado and Wyoming states. and African regions in winter and South America in summer.

The difference of two numbers is 9 if the larger number is one more than twice the smaller number find the larger number
Answers
Answer:
17
Step-by-step explanation:
let the two numbers be X and Y
let larger number = Y
from the first statement
Y - X = 9 equation (1)
from the second statement
Y = 1+ 2X equation (2)
substitute equation (2) into (1)
1+2X-X = 9
1+X= 9
X = 9-1 = 8
X= 8
put X = 8 into equation (2)
Y= 1+2X
Y= 1+2(8)
Y= 1+16 = 17
larger number = 17.
If the chance of getting a disease is 20 out of 100, this would be the same as having a ______ % chance
Answers
Answer:
20
Step-by-step explanation:
To calculate percent from a fraction, you can multiply the value of the fraction by 100. 20/100*100 is 20, so there is a 20% chance.
The required blank space could be filled with 20% as, If the chance of getting a disease is 20 out of 100, this would be the same as having a 20% chance.
Given that,
If the chance of getting a disease is 20 out of 100, this would be the same as having a ______ % chance, to determine what value can be put.
The percentage is the ratio of the composition of matter to the overall composition of matter multiplied by 100.
Here,
According to the question,
percentage of get affected by disease = 20 / 100 = 0.20 or 20%
Thus, the required blank space could be filled with 20% as, If the chance of getting a disease is 20 out of 100, this would be the same as having a 20% chance.

Answers
Answer:
x = 1.5 or 3/2
Step-by-step explanation:
First, expand the equation.
(2x - 3)² = 0
(2x - 3)(2x - 3) = 0
In similar equations, we would solve for both pairs of parenthesis. However, since the equations inside both are the same, we only need to solve for ONE of them, bringing one correct answer.
2x - 3 = 0
Add 3 to both sides.
2x = 3
Divide both sides by 2.
x = 3/2 or 1.5.

Explanation:
The tickmarks tell us that sides HG and FG are the same length. The triangle is isosceles. Directly from this, we know that the opposite angles F and H are congruent. Both are 4y-7 degrees.
Angle G is 90 degrees because of Thales' Theorem. This is because HF is the diameter of the circle. It's also the hypotenuse of the right triangle.
For any triangle, the three interior angles always add to 180 degrees.
F+G+H = 180
(4y-7) + (90) + (4y-7) = 180
8y + 76 = 180
8y = 180-76
8y = 104
y = 104/8
y = 13

Rationalising the denominator of the given fraction means we need to multiply both the numerator and the denominator of the fraction by the conjugate of the expression in the denominator. For example:
[tex]\;\longrightarrow\dfrac{1}{a+b}[/tex]
Here the conjugate of denominator of the expression is a - b. So we need to multiply both the numerator and denominator with the fraction.
[tex]\;\longrightarrow \dfrac{1}{a+b} \times \dfrac{a-b}{a-b}[/tex]
Hence, this is what the rationalization means.
Elucidation:We have been given and equation and we have been asked to rationalise the equation.
The conjugate of the denominator of the given equation is √(x² + y²) - x. Therefore;
[tex]\implies \dfrac{y^2}{\sqrt{x^2+y^2}+x} \times \dfrac{\sqrt{x^2+y^2}-x}{\sqrt{x^2+y^2}-x}[/tex]
[tex]\implies \dfrac{y^2(\sqrt{x^2+y^2}-x)}{(\sqrt{x^2+y^2}+x)(\sqrt{x^2+y^2}-x)}[/tex]
[tex]\implies \dfrac{y^2(\sqrt{x^2+y^2}-x)}{(\sqrt{x^2+y^2})^2-x^2}[/tex]
[tex]\implies \dfrac{y^2(\sqrt{x^2+y^2}-x)}{x^2+y^2-x^2}[/tex]
[tex]\implies \dfrac{y^2(\sqrt{x^2+y^2}-x)}{y^2}[/tex]
[tex]\implies \boxed{\sqrt{x^2+y^2}}[/tex]
Hence, this is our required solution for this question.

Answers
Answer:
[tex]\boxed{\sf{r=-\dfrac{2}{3} }}[/tex]Step-by-step explanation:
Isolate the term of r, from one side of the equation.
3/2r=-1First, multiply by 2 from both sides.
2*3/2r=2(-1)
Solve.
3r=-2
Then, you divide by 3 from both sides.
3r/3=-2/3
Solve.
Divide the numbers from left to right.
r=-2/3

Step-by-step explanation:
Given equation:

To determine the solution (x) of the equation, we need to isolate it. To do this, we can subtract 2 both sides of the equation.
[tex]\implies 5 - 2 = \dfrac{x}{3} + 2 - 2[/tex]
[tex]\implies 3 = \dfrac{x}{3}[/tex]
To further isolate "x", we can use cross multiplication.

SolveSo, we know that tantheta is 0.75, or 3 quarters, but we have to find the value of sintheta. If there are 4 angles on a triangle, we can label them as BC and AB.[tex]because~of~the~angles\\BC = 3k\\AB = 4k[/tex]
Now, we must find the value of AC using the pythagoras theorem.⇒ (AB)² + (BC)² = (AC)²
in which because of AB and BC's values, goes into...
⇒ (4k)² + (3k)² = (AC)²
because of that ↑ you get the values of what is below.
⇒ (AC)² = 16 k² + 9 k²
add 16k and 9k for the result below.
⇒ (AC)² = 25 k²
⇒ AC = ±5k
Hmm. An angle cannot be negative, so turn 5k to positive 5k. Last but- not least, we have to find the sintheta.the sin is the side opposite to the angle, so find the hypotenuse and opposite angle.
[tex]Side~opposite~to~angletheta\\= BC(3k)\\\\Hypotenuse\\= AC(5k)[/tex]
That said → [tex]sintheta = \frac{BC}{AC} = \frac{3k}{5k} = \frac{3}{5}[/tex]
