Answer:
1 d know
Step-by-step explanation:
the correct use of the distance formula is the equation :
√((27 - 12)² + (y₂ - 15)²).
What are coordinates?A pair of numbers called coordinates are used to locate a point or a form in a two-dimensional plane. The x-coordinate and the y-coordinate are two numbers that define a point's location on a 2D plane.
Given a diagram of a line for that distance, the line needs to find
the general formula for distance
d = √((x₂ - x₁)² + (y₂ - y₁)²)
Thus, for the given coordinates formula for distance
d = √((27 - 12)² + (y₂ - 15)²)
therefore, the equation √((27 - 12)² + (y₂ - 15)²) is the correct use of the distance formula.

−2k+7x+33
Step-by-step explanation:
Write a rule in function notation to describe the transformation that is a reflection across the x-axis.
Answer:
R(x, y) = (x, -y)
Step-by-step explanation:
When we have a reflection across some line, the distance between the original point and the reflected point to the line is invariant.
For a reflection around the x-axis, the x-value is invariant, then the only value that can change is the y-value.
So if we have a point like (4, 7)
Which is at a distance of 7 units to the x-axis, the only other point that is also at a distance of 7 units to the x-axis that has the same x-value is (4, -7)
Here we already can see the rule.
If we have a point (x, y), the reflection across the x-axis gives us the point (x. -y)
Then we can write this reflection as a function in the next way:
R(x, y) = (x, -y)
This means that if the input is the point (x, y), the output is the point (x, -y)

3. A circle with center (0,0) has a y-intercept at (3,0).
Find the equation of the circle.
Answer:
x^2 + y^2 = 9
Step-by-step explanation:
The standard equation of a circle with center at (h, k) and radius r is
(x - h)^2 + (y - k)^2 = r^2. Here h = 0, k = 0, x = 3 and y = 0:
(3 - 0)^2 + (0 - 0)^2 = r^2, or
9 = r^2. Thus, the radius is 3.
The equation of this circle is (x - 0)^2 + (y - 0)^2 = 9, or
x^2 + y^2 = 9

There are 4.9 x 10³ times greater is the mass of a gold atom than the mass of a helium-4 atom.
What is Division method?Division method is used to distributing a group of things into equal parts. Division is just opposite of multiplications.
For example, dividing 20 by 2 means splitting 20 into 2 equal groups of 10.
We have to given that;
The mass of a gold atom is 3.29 x 10⁻²² grams.
And, The mass of a helium-4 atom is, 6.65 x 10⁻²⁴ grams.
Hence, The amount of greater is the mass of a gold atom than the mass of a helium-4 atom is,
⇒ 3.29 x 10⁻²² / 6.65 x 10⁻²⁴
⇒ 0.49 x 10²
⇒ 4.9 x 10³
Thus, There are 4.9 x 10³ times greater is the mass of a gold atom than the mass of a helium-4 atom.

Lilly sells 4 boxes of cookies in 60 minutes, at this rate how long will it take her to sell 10 boxes?
Answer:
150 minutes ! 60/4 multiplied by 10!
Step-by-step explanation:
Answer:
Step-by-step explanation:To find out how long it takes her to sell one box you see how many times 4 can go into 60 to get how long it takes to sell one box. So in this case it takes 15 minutes to sell one box. So you take 15 and multiply it by 10. 15 * 10= 150
60/4=15
15*10=150
So it takes 150 minutes to sell 10 boxes of cookies.

Answer:
A. 201 cm³
Step-by-step explanation:
To find the volume, we need to know the length of the prism and the area of the triangular base.
We can find the area of the triangular base a couple of ways. Since we are given some angles, the convenient way will be to make use of those angles.
The triangular base is isosceles. For our purpose, we assume that means AB = BC. If we define point M as the midpoint of AC, then triangle BMC is a right triangle with a base of (9 cm/2) = 4.5 cm.
The side BC can be found from the trig relation ...
cos(∠BCA) = CM/BC
BC = CM/cos(∠BCA) = (4.5 cm)/cos(50°) ≈ 7.00
Then the area of the end triangle ABC is ...
base area = (1/2)(AC)(BC)sin(50°)
base area = (1/2)(9 cm)(7 cm)sin(50°) ≈ 24.133 cm²
__
The length CF can be found from the relation ...
tan(40°) = EF/CF
CF = EF/tan(40°) = (7.00 cm)/tan(40°) ≈ 8.343 cm
Then the volume of the prism is ...
V = Bh
V = (24.133 cm²)(8.343 cm) ≈ 201 cm³
The volume of this isosceles triangular prism is about 201 cm³.
Answer:
A. 201 cm³ is the answer.

Find the equation of the straight line having a slope root 3 and passing through the point(-1,5)
Given:
Slope of a straight line is [tex]\sqrt{3}[/tex].
The line passing through the point (-1,5).
To find:
The equation of the straight line.
Solution:
The point slope form of a line is:
[tex]y-y_1=m(x-x_1)[/tex]
Where, m is the slope and [tex](x_1,y_1)[/tex] is the point.
The line passing through the point (-1,5) with slope [tex]\sqrt{3}[/tex]. So, the equation of the line is:
[tex]y-5=\sqrt{3}(x-(-1))[/tex]
[tex]y-5=\sqrt{3}(x+1)[/tex]
[tex]y=\sqrt{3}x+\sqrt{3}+5[/tex]
Therefore, the equation of the straight line is [tex]y=\sqrt{3}x+\sqrt{3}+5[/tex].

Sheila is twice as old as Rita. In two years, Sheila will be four times as old as Rita was nine years ago. How old is each now?
Answer: (Sorry for not wording it correctly I had to reword it)
Step-by-step explanation: Let R be the current age of Rita. Let S be the current age of her son.
Rita is twice as old as her son.
=> R = 2S
In 4 years, R will be 4 times as old as S was 9 years ago
=> R + 4 = 4 (S - 9)
Solve for R, and S:
=> R + 4 = 4 (S - 9)
=> (2S) + 4 = 4(S - 9)
=> 2S + 4 = 4S - 36
=> 2S - 4S = -36 - 4
=> -2S = -40
=> S = 20
Find R:
=> R = 2S
=> R = 2(20)
=> R = 40
Therefore, Rita is 40, her son is 20.
