<span>When converting a number with meters per second to a value with kilometers per second they best way to perform this operation is by using dimensional analysis or the factor label method. You would set up the equation starting with 5120 m/s times 1 km / 1000 m times 3600 s / 1 hr. It would look like this:
(5120 m/ 1 s) x (1 km / 1000 m) x (3600 s / 1 hr)
Your next step would be multiplying all the top numbers (numerators) together 5120 x 1 x 3600 = 18,432,000
Now multiple on the bottom numbers (denominators) together
1 x 1000 x 1 = 1000
Now you can divide the top product by the bottom product. 18,432,000 / 1000 = 18,432 km/hr is your final answer.</span>
Solve for d: by simplifying both sides of the equation, then isolating the variable.
C. d>0
Standard form: Ax + by =C
so
y+ 1 = 3/4(x - 16)
4(y + 1) = 3(x - 16)
4y + 4 = 3x - 48
3x - 4y = 52
Answer is D. last option
3x - 4y = 52
Step-by-step explanation:
Remember when expanding radicals,
When expanding radicals into two radicals, we don't let our radicand have two negative answers.
We don't do this
The slope of the parallel line is -6/7
the slope of the perpendicular line is 7/6
the slope of the line = -6/7
the gradient of two parallel lines are equal
the product of the gradient of two perpendicular lines is -1
: the gradient m1*m2 = -1
m2= -1(-6/7)
m2= 7/6
