Answer:
6.42 dollar
Step-by-step explanation:
(3.5+2.5)x0.07+(3.5+2.5)
=(3.5+2.5)x(1+0.07)
=6x1.07
6.42
B.(7.5, –3.5) and (7.5, 3.5)
C.(7.5, 1.2) and (7.5, 2.3)
D.(7.5, –3.5) and (7.5, 7)
The points between whom the distance is 3.5 units apart are (7.5, 1.2) and (7.5, -2.3).
Given is to find the points between whom the distance is 3.5 units apart.
Using the distance formula for the points (7.5, 1.2) and (7.5, -2.3), we get-
d² = (- 2.3 - 1.2)² + (7.5 - 7.5)²
d² = (3.5)²
d = 3.5 units
Therefore, the points between whom the distance is 3.5 units apart are (7.5, 1.2) and (7.5, -2.3).
