Can anyone please help me IM not sure if the first one is correct
Answer:
you are correct keep up the good work.
Answer:
The 1st one is correct and the second one is (5, -3)
Step-by-step explanation:
For the 1st question this is what I did:
d=√(x^2−x^1)^2+(y^2−y^1)^2
d=(0−4)^2+(6−3)^2
√d=(−4)^2+(3)^2
√d=16+9
√d=25
√d=5
For the second question I did this:
(xM,yM)=(x1+x2/2,y1+y2/2)
M=(xM,yM)
M=(x1+x2/2,y1+y2/2)
M=(3+7/2,−1+−5/2)
M=(10/2,−6/2)
M=(5,−3)
Hope this helps!

A flower vase is in the shape of a cylinder and has a diameter of 5 inches and a height
of 7 inches. which equation could be used to determine the volume, in cubic inches,
of the vase?
Answer:
V = π(2.5)²(7)
Step-by-step explanation:
Given:
A flower vase is in the shape of a cylinder and has a diameter of 5 inches and a height of 7 inches.
To Find:
which equation could be used to determine the volume, in cubic inches, of the vase?
Solve:
Formula for cylinder volume: Volume = πr²h
Where,
h represents the height of the cylinder
r represents the radius of the cylinder.
π is a constant whose value is 3.14
Knowing that:
Diameter = 5 in
Height = 7 in
Radius = 2.5 {Radius is half of diameter so 5/2 = 2.5}
Thus, a equation could be use is:
V = π(2.5)²(7)

-5x + 2y = -29
5x - 2y = 24
Answer:
-10x + 4y = -53
Step-by-step explanation:
-5x+2y = -29
5x - 2y = 24
subtract both values from up to down
-5x - 5x = -10x
2y - (-2y) = 4y
-29 - 24 = -53
-10x + 4y = -53

Which pair of expressions has the same value?

B. (2)(7) and 4 + 18
C. (–2)(7) and 18 + (–4)
D. (2)(–7) and 4 – 18
Assuming that (-2)(-7) and 4 + (-18) are equal.
⇒ (-2)(-7) = 4 + (-18)Using the property [-x × -y = x × y = xy]:
⇒ (-2)(-7) = 4 + (-18) ⇒ (2)(7) = 4 + (-18)Using the property [x + (-a) = x - a]:
⇒ (2)(7) = 4 + (-18)⇒ (2)(7) = 4 - 18⇒ 14 = -14 (False)Option B)Assuming that (2)(7) and 4 + 18 are equal.
⇒ (2)(7) = 4 + 18⇒ 14 = 22 (False)Option C)
Assuming that (–2)(7) and 18 + (–4) are equal.
⇒ (-2)(7) = 18 + (-4)Using the property [-x × y = -xy]:
⇒ (-2)(7) = 18 + (-4)⇒ (-)(2)(7) = 18 + (-4)⇒ -14 = 18 + (-4)Using the property [x + (-a) = x - a]:
⇒ -14 = 18 + (-4)⇒ -14 = 18 - 4⇒ -14 = 14 (False)Option D)
Assuming that (2)(-7) and 4 - 18 are equal.
⇒ (2)(-7) = 4 - 18Using the property [-x × y = -xy]:
⇒ (-)(2)(7) = 4 - 18⇒ -14 = 4 - 18⇒ -14 = -14 (True)Therefore, Option D is correct.

A maple tree is 6 meters tall. Its shadow is 8 meters long. Close by, there is a streetlamp
that is 9 meters tall. How long is the streetlamp's shadow?
Write your answer as a whole number or a decimal. Do not round.
meters
Answer:
12 meters
Step-by-step explanation:
The assumption regarding shadow lengths is that they are proportional to height at any given place and time.
__
Here, the streetlamp is 9/6 = 3/2 times as tall as the tree, so we expect its shadow to be 3/2 times the length of the tree's shadow.
(3/2)(8 m) = 12 m
The streetlamp's shadow is 12 meters long.

How many yards are equivalent to 38 feet? 1 yard = 3 feet
Answer:
13 yards
Step-by-step explanation:
38/3 => 12.6667 yards which would be closest to 13 yards
The formula is to divide the lenght value by 3.
The number 38 feet is equal to 12.67 yards.
We have to give that,
To change 38 feet into yards.
Since we know that,
1 yard = 3 feet
1 feet = 1/3 yards
Hence, change 38 feet into yards as,
1 feet = 1/3 yards
38 feet = 38/3 yards
38 feet = 12.67 yards

Which of these intersections of a plane and a three dimensional figure result in a triangular cross section
Answer:
top right one
Step-by-step explanation:
Top left one makes a square
bottom left one makes a circle
top right one makes a triangle
bottom right one makes a circle
The intersection of a plane and a three-dimensional figure results in a triangular cross-section is a triangular pyramid.
What is a cross-section?A solid's cross-section is a plane figure formed when the solid intersects another plane. As a result, the cross-section of an object is an infinitesimal "slice" of a solid, and it can vary depending on how the slicing plane is oriented. A sphere's cross-section is always a disk, although a cube's cross-section can be square, hexagonal, or another shape.
In these types of three-dimensional geometrical problems imagination of the figures is very crucial.
Now, Think of the plane as a very very thin sheet cutting a triangular pyramid parallel to its base will have exactly the same cross-section as its base and we know a triangular pyramid has a triangular base.
