Answer:
we get Rate of change = -3
Step-by-step explanation:
We need to calculate the rate of change for the following data:
x y
-1 7
2 -2
7 -17
10 -26
The rate of change can be calculated using slope formula:
From the table, we can take any 2 points
Suppose we take (-1,7) and (2,-2)
We have:
Putting values in formula and finding rate of change
So, we get Rate of change = -3
Answer:
Step-by-step explanation:
<u>Use midpoint formula to calculate x or y- coordinates.</u>
- A(x₁, y₁), B(x₂, y₂)
- M = ((x₁ + x₂)/2, (y₁ + y₂)/2)
Answer:
see explanation
Step-by-step explanation:
(1)
Volume (V) of prism = area of triangular end face × length
V = × 4.2 × 4.7 × 6.4 ≈ 63.17 mi³
(2)
Volume of a cuboid = lbh
where l is the length, b the breadth and h the height
l = x, b = 4, h = 9 and V = 972, thus
x × 4 × 9 = 972
36x = 972 ( divide both sides by 36 )
x = 27
(3)
V = area of triangular end × length, thus
× 6 × x × 9 = 234.9
27x = 234.9 ( divide both sides by 27 )
x = 8.7
4x^2y(x+2)-x(xy2-3)
(4x^2y)^(x)+(4x^2y)(2)-x^2y^2+3x
4x^3y+8x^2y-x^2y^2+3x
4x^3y-x^2y^2+8x^2y+3x
This was very confusing to solve so sorry if I’m wrong.Also sorry if it’s too hard to write it.
