Answer:
(-1,-2)
Step-by-step explanation:
The given coordinates are ,
G ( 4 , 10)
H ( -2 , -6)
Midpoint can be calculated by finding the mean of x coordinates and y coordinates . As ,
→ Midpoint = ( 4-2/2 , 10-6/2)
→ Midpoint = ( -2/2 , -4/2 )
→ Midpoint = ( - 1 , -2)
Hence the midpoint is (-1,-2)PART B:To find out the midpoint,here's the formula: ((x1+x2)÷2 , (y1+y2)÷2)
Thus,the midpoint of QS is
((4+(-2))÷2 , (10+3)÷2)
=(1 , 13/2)

How to find the surface area of a triangular prism
Answer:
See below.
Step-by-step explanation:
To find the surface area, find the area of the square base and add it to the area of each triangle face. Find the area of the base by multiplying base length by base length. Find the area of each triangle face by multiplying 1/2 * b*h.
Example:
For a base which is 12 by 12. The area is 12 x 12 = 144.
For the triangle face, the area is 1/2 * 12 * 15 = 90. Since there are 4 faces, the total area is 4 * 90 = 360.
Together the surface area is 360 + 144 = 504.

What expression is equivalent to 1-2 sin^2x?
I know the answer is 2cos^2x-1, but unsure how to solve it. Do I use the Pythagorean identity to start?
Thanks!
Answer:
1-2*sin^2 (x) = 2cos^2(x) -1
Step-by-step explanation:
1-2sin^2(x)
= 1-2(1-cos^2(x)) =2cos^2(x)-1; Pythagorean identity, sin^2(x)=1-cos^2(x)
=1-2+2cos^2(x)=2cos^2(x)-1; distribute
= -1+2cos^2(x)=2cos^2(x) -1; collect and rearrange terms
= 2cos^2(x)-1 = 2cos^2(x)-1
A large rectangular prism has a length of 2 and 1/2 inches, a width of 4 inches, and a height of 1 and 1/2 inches. A smaller cube has a length, width, and height of 1/2 of an inch. How many of the smaller cubes will fit into the larger rectangular prism?
Answer:
120 cubes
Step-by-step explanation:
Volume of prism and cube:We can find the number of smaller cubes that will fit into larger rectangular prism by dividing the volume of prism by the volume of cube.
Rectangular prism:
[tex]\sf l = 2\dfrac{1}{2} =\dfrac{5}{2} \ inches\\\\w = 4 \ inches\\\\h =1\dfrac{1}{2}=\dfrac{3}{2} \ inches\\[/tex]
[tex]\sf \boxed{\text{\bf Volume of rectangular prism= l * w * h}}[/tex]
[tex]\sf =\dfrac{5}{2}*4*\dfrac{3}{2}\\\\= 5*1*3\\\\= 15 \ in^3[/tex]
Cube:
[tex]\sf side = \dfrac{1}{2} \ inches\\[/tex]
[tex]\sf \boxed{\text{ \bf Volume of cube = side * side *side}}[/tex]
[tex]\sf =\dfrac{1}{2}*\dfrac{1}{2}*\dfrac{1}{2}\\\\ =\dfrac{1}{8} \ in^3[/tex]
Number of cubes = Volume of prism ÷ volume of a cube
[tex]\sf = 15 \div \ \dfrac{1}{8}\\\\=15 *\dfrac{8}{1}\\\\= 120[/tex]
120 cubes will fit
Write 10 3 8 as an improper fraction.
Answer (if the number is 10 3/8):
83/8
Step-by-step explanation:
to find out we multiply the whole number (10) by the denominator (x/8) as shown below
10 * 8 = 80
then we just add the product to the numerator (3/y)
3 + 80 = 83
usually we would simplify the new expresion given -wich is 83/8- by finding the least common denominator, however this improper fraction is already in simplest form

The value of y in y = 5x if the value of x doubles itself is y also doubles itself; option A
How to solve equation?y = 5x
if x = 2
y = 5(2)
y = 10
if the value of x doubles, for instance, if x = 4
y = 5(4)
y = 20
y = 5/x
if x = 0.5
y = 5/0.5
y = 10
if the value of x triples, for instance, if x = 0.125
y = 5/x
= 5/0.125
y = 40
The value of y in y = 5/x if the value of x triples itself is y also triples itself; option B

A 1-quart milk carton has a square base of 7 cm × 7 cm and a height of 19.3 cm. What is its volume in cubic centimeters?
Answer:
V = 945.7 cm^3
Step-by-step explanation:
I'm assuming the carton is a rectangular prism/has right angles. The volume formula for a rectangular prism is V = lwh, where l = length, w = width, h = height.
Substitute known values into this formula:
V = 7 × 7 × 19.3
V = 945.7 cm^3

What is line?A line is a one-dimensional figure, which has length but no width. A line is made of a set of points which is extended in opposite directions infinitely.
Given function: y = 2x + 7.
As the graph of function 1 is not given.
the rate of change of function 2 : y = 2x + 7.
As the the value of m or rate of change of above equation is 2
m=2.
as, the horizontal line passes, the rate of change is 0

Answer:
39 yd^2
Step-by-step explanation:
First, we must divide the shape into quadrilaterals. The best, and easiest, way to do this is to cut along the line in the middle, below the lower 2 yd mark. This will give us a 1 yard by 3 yard rectangle, 4 yard by 8 yard rectangle, and 2 yard by 2 yard square. The next thing to do is to find the area of each location of the backyard using the A = l x w equation. 1 x 3 = 3, 2 x 2 = 4, 4 x 8 = 32. The final step is to add these individual areas, giving us 39 square yards.
