Answer:
Step-by-step explanation 10 + 2.50d = 850
David starts with $10 and each day he earns $2.50. The d represents a variable and can be any number.
To find d you must solve the equation.
10 + 2.50d = 850
2.50d = 840 (subtract 10 from 850)
d = 336 (divide 840 by 2.50)
It will take David 336 days to save $850.
Answer:
The change in elevation is -134 ft
Step-by-step explanation:
Given;
initial depth of the submarine, d₁ = 235 ft
final depth of the submarine, d₂ = 101 ft
The change in the elevation of the submarine is given by;
Δd = d₂ - d₁
Δd = 101 ft - 235 ft
Δd = -134 ft
The change in elevation is negative because the submarine is moving closer to the surface.
Therefore, the change in elevation is -134 ft
Answer:
a) P = (-3, 4, 3)
b) P = (7, 4, 1)
Step-by-step explanation:
a) You want Q-P = (5, 4, -1) where Q = (2, 0, 2). Solving for P, we get ...
P = Q - (5, 4, -1) = (2-5, 4-0, 2-(-1))
P = (-3, 4, 3)
__
b) The vector in the opposite direction of the one given is the given one multiplied by -1.
P = Q - (-1)(5, 4, -1) = (2+5, 0+4, 2-1)
P = (7, 4, 1)
