Multiply this 15 mph by the conversion factor derived from 1.6 km = 1 mi:
15 mph 1.6 km
------------ * ---------- = 24 km/hr
1 1 mi
The cyclist's speed in km/hr is 24 km/hr.
In 3 hrs the cyclist can cover (24 km/hr)(3 hr) = 72 km.
Is this simultaneous equations?
if yes then the first step is
make one of the unknown as the subject
To get this, you need to divide 15/16 by 1/16. To do it, multiply 15/16 by 16 and you get 15 as your answer.
Answer:
y=6
Step-by-step explanation:
Differentiate the equation
dy/dx=2x-8
Find the value of x in equation form
2x-8=0
x=8/2=4
Now x=4 is the line of symmetry or the parabola of the quadratic equation.
Plug back x=4 into the equation to find the turning point(minimum value)
y=(4)²-8(4)+22
y=16-32+22
y=6
No, a lone variable has an invisible one in front of it, So 4z (can’t put the top number sorry) So 4z - z would equal 3z
