The distance between any two points is:
d^2=(x2-x1)^2+(y2-y1)^2 so in this case:
d^2=(7-4)^2+(-3-6)^2
d^2=3^2+9^2
d^2=90
d=√90
d=3√10 units
d≈9.49 units (to nearest hundredth of a unit)
7.8456 x 10^(-4)
this means you move the decimal place to the left 4 places to get the actual value
Answer:
0
Step-by-step explanation:
- 2×3= - 6
2×3=6
-6+6=0
Answer:
slope = - 32 , y- intercept = 5
Step-by-step explanation:
the equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
y = - 32x + 5 ← is in slope- intercept form
with slope m = - 32 and y- intercept c = 5
Answer:
Step-by-step explanation:
For this question, set u = arctan(x). This would be the easiest way because the derivative of arctan(x) is 
which is what we have. Before setting u, always look at the question and think about possible derivatives.
Next, plug in u and du.
(rearranging)
Substitute arctan(x) back in for u and add +C.
