Answer:
Options B and D
Step-by-step explanation:
we have
-----> equation A
-----> equation B
Solve the system of equations by graphing
The solution of the system of equations is the intersection point both graphs
The solutions are the points (1.545,-0.687) and (2.956,-22.835)
see the attached figure
The approximate solutions are
(1.5,-0.7) and (2.9,-22.8)
If you multiply .8*.007=<span>0.0056</span>
A^2 + b^ = c^2
c is the longest side of the triangle
a and b are the other two sides
So the given are the hypotenuse leg, and one of the other legs
So
a= ?
b= 12
c= 14
a^2+12^2=14^2
a^2+144=196
-144 -144
a^2=52
So we find the square root of 52
Which is 7.211 which you can round to 7.21 or 7.2
D = m/v
v*d = v*(m/v) ... multiply both sides by v
v*d = m
(v*d)/d = m/d ... divide both sides by d
v = m/d
--------------------------------
After we solve for v (aka isolate v), we end up with this final answer
v = m/d
