Step-by-step explanation:
40 + 10.5 + (7% of 40)
50.5 + (7/100 × 40)
50.5 + 2.8
53.3
Answer:
5 units
Step-by-step explanation:
Find the distance between the point - 3, 2 and 1 - 1
Given data
x1= -3
y1= 2
x2= 1
y2= -1
The expression for the distance between two points is
d=√((x_2-x_1)²+(y_2-y_1)²)
subtitute
d=√((1-(-3))²+(-1-(2))²)
d=√((1+3))²+(-1-2))²)
d=√((4)²+(-3))²)
d=√16+9
d=√25
d=5
Hence the distance between the points is 5 units
Find the product.3y^2 z(2y^2 z + 4yz - y + z)
3y^2 (2z^2y^2 + 4yz^2 - zy + z^2
6z^2y^4 + 12z^2y^3 - 3zy^3 + 3z^2y^2
