Final answer:
To find the coordinates of point P2 when given the midpoint M(-1, 5) and point P1(-4, 6), we use the midpoint formulas, resulting in P2 having the coordinates (2, 4).
Explanation:
The midpoint of a line segment is the point that is exactly halfway between the endpoints of the line segment. By definition, the midpoint M(x, y) can be found using the endpoints P1(x1, y1) and P2(x2, y2) with the formulas:
x = (x1 + x2)/2y = (y1 + y2)/2To find P2, we solve for x2 and y2 using the midpoint M(-1, 5) and the given point P1(-4, 6):
x2 = 2x - x1 = 2(-1) - (-4) = -2 + 4 = 2y2 = 2y - y1 = 2(5) - 6 = 10 - 6 = 4Therefore, the coordinates of point P2 are (2, 4).
Final answer:
The coordinates of P2 are (6, 4).
Explanation:
The midpoint of a line segment can be found by taking the average of the x-coordinates and the average of the y-coordinates of the two endpoints. In this case, the midpoint is (-1, 5), and one endpoint is (-4, 6). To find the other endpoint, we can use the formula:
x-coordinate of P2 = 2 * (x-coordinate of midpoint) - x-coordinate of P1 = 2 * (-1) - (-4) = 2 + 4 = 6
y-coordinate of P2 = 2 * (y-coordinate of midpoint) - y-coordinate of P1 = 2 * (5) - 6 = 10 - 6 = 4
Therefore, the coordinates of P2 are (6, 4).

A parabola has a vertex at (0,0). The focus of the parabola is located on the positive x-axis. Which part of the graph will the directrix pass through? the origin the negative part of the x-axis the positive part of the x-axis the negative part of the y-axis
Answer with explanation:
→→Information given about Parabola
Vertex of the Parabola = (0,0)
Focus is located on the positive x- axis.
Definition of Parabola: A parabola is locus of all the points such that distance from a fixed point known as focus to distance from a fixed line called, Directrix is always constant.
Let focus of the parabola be (k,0), where , k>0.
Distance between vertex (0,0) and focus(k,0) = Distance between vertex (0,0) and point on negative x-axis (-k,0).
Directrix will pass through point (-k,0).
So, equation of Directrix will be, x= -k
Directrix will pass through
Option B: The Negative part of the x -axis.

Can every even number be written as a sum of two primes?
Final answer:
No, not every even number can be written as a sum of two primes. This is known as the Goldbach Conjecture, which states that every even number greater than 2 can be expressed as the sum of two prime numbers.
Explanation:
No, not every even number can be written as a sum of two primes. This is known as the Goldbach Conjecture, which states that every even number greater than 2 can be expressed as the sum of two prime numbers. So far, this conjecture has been tested for even numbers up to at least 4, and no counterexamples have been found. However, it has not been proven to be true for all even numbers.
For example, the number 4 can be expressed as the sum of two primes (2 + 2), but the number 6 cannot be expressed as the sum of two primes. On the other hand, the number 8 can be expressed as the sum of two primes (3 + 5). This pattern continues, with some even numbers being expressible as the sum of two primes and others not.

In the neighborhood park there is a circular grassy picnic area, but half of the grass has died. The city wants to replant the grads, but needs to know the square footage of the damaged area. If the circular picnic are is 150 feet across what is the square footage of the damaged area
Answer: The damaged area is equal to 8831.25ft^2
Step-by-step explanation:
We know that we have a circular area, where half of the grass has died. We know that the circular picnic is "150 feet across" I guess this means that if you walk in a straight line from the edge of the circular area, through the middle, and to the next edge, the distance is 150ft.
This would mean that the diameter is equal to 150ft.
With this we can calculate the total area of the circle; this is:
A = pi*r^2
where r is the radius, that is half the diameter, so we have r = 150ft/2 = 75ft
and pi = 3.14
so we have:
A = 3.14*(75ft^)^2 = 17662.5ft^2
And we know that half of that area has the grass damaged, so the amount of square feet of grass needed is equal to A/2 = (17662.5ft^2)/2 = 8831.25ft^2

A single card is drawn from a deck. find the probability of selecting a heart or a 8.
Answer with Step-by-step explanation:
Let
A:selecting a heart
Total cards=52
number of hearts=13
P(A)=13/52
B:selecting a 8
number of 8=4
P(B)=4/52
A∩B:selecting a heart with 8 on it
number of hearts with 8 on it=1
P(A∩B)=1/52
A∪B:selecting a heart or a 8
We have to find P(A∪B)
P(A∪B)=P(A)+P(B)-P(A∩B)
= [tex]\dfrac{13}{52}+\dfrac{4}{52}-\dfrac{1}{52}[/tex]
=[tex]\dfrac{13+4-1}{52}[/tex]
= 16/52
= 4/13
Hence, the probability of selecting a heart or a 8 is:

d) The image of the point (-6,-6) under a reflection across the y=x is (-6,-6).
e) The image of the point (2,4) under a reflection across the y-axis followed by a reflection across y=xis (-2,-2).
f) Point K (3,-1)is reflected across the x-axis to creak point K'.The line x+3y=6 passes through point K'.
Answer: The answer in order are false, false, true, true, false and (3,1)
Step-by-step explanation:
We know that image of a point (x,y) under the y-axis
is (-x,y) i.e. the sign of x coordinate changes
Similarly in case of x-axis sign of y coordinate changes
i.e (x,y) is reflected to (x,-y)
Also the reflection of (x,y) under the line y=x is (y,x)
and the reflection of (x,y) under the line y=-x is(-y,-x)
So
a) Given image of (-3,-5) under x-axis is (3,-5).
Hence statement is false
b) Given image of (1,9) under y-axis is (1,-9)
Hence the statement is false
c) Given image of (8,7) under y=-x is (-7,-8)
i.e. the statement is true
d) Given image of (-6,-6) under y=x is (-6,-6)
i.e the statement is true
e) Given image of (2,4) under y axis followed by x-axis is (-2,-2)
Hence the statement is false
f) (3,-1) is reflected in x-axis to (3,1)
Hence the point k is (3,1)

a local post office sells stamps in packs of 4, 6 and 7. andy bought several packs of 4. erin bought several packs of 6. jarred bought several packs of 7. each of the three friends ended up with the same number of stamps that each person could have purchased?
The number of stamps each could have purchased is 84
How to determine the number of stamps each purchased
From the question, we have the following parameters that can be used in our computation:
Andy = packs of 4
Erin = packs of 6
Jarred = packs of 7
Expand 4, 6 and 7
So, we have
4 = 2 * 2
6 = 2 * 3
7 = 7
The LCM of 4, 6 and 7 is then calculated as
LCM = 2 * 2 * 3 * 7
Evaluate
LCM = 84
Hence, the number of stamps each could have purchased is 84

Bill needs to find the area of the ground covered by a conical tent. The tent is 12 feet tall and makes a 70° angle with the ground. Which expression can be used to find the area?
a) π · (12 · tan 70°)2
b) 36 · π
c) π · (12tan 70°12tan 70°)2
d) π · (tan 70°12tan 70°12)2
a) π · (12 · tan 70°)2. To find the area of the ground covered by the conical tent, use the formula for the surface area of a cone, A = πr(r+√(r^2+h^2)).
Explanation:To find the area of the ground covered by the conical tent, we can use the formula for the surface area of a cone. The formula is A = πr(r+√(r^2+h^2)), where r is the radius and h is the height of the cone.
In this case, the height of the cone is 12 feet and the angle it makes with the ground is 70°. To find the radius, we can use trigonometry. The radius is given by r = h tanθ, where θ is the angle with the ground. Plugging in the values, we get r = 12 tan(70°).
Now, substituting the value of r into the formula for the surface area of the cone, we get A = π(12 tan(70°))(12 tan(70°)+√((12 tan(70°))^2 + 12^2)). This simplifies to option a) π · (12 · tan 70°)2.

What is a Fraction?A fraction is a way to describe a part of a whole. such as the fraction 1/4 can be described as 0.25
If we look at each of the shapes, we can observe that the whole of the shape is shaded therefore, the shaded part of the shape is equal to the shape which is represented by 1.
Now, in the image, there are two shapes given each of which is completely shaded, and the whole shape is represented by 1. therefore, these two shapes will be represented by 2.
The shaded shape can be written as,
[tex]2 = \dfrac{2}{1}[/tex]
Hence, the fraction is represented by the shaded part of the model is [tex]\dfrac{2}{1}[/tex].
