depth at point B = 5 m
Step-by-step explanation:
y = -(2/5)x - 1
Point C is located 10 m from the origin O which means that x = 10. Using this value in our equation,
y = -(2/5)(10) - 1
= -4 - 1
= -5
Answer: Hello mate!
you know that the equation is (or at least i think this is):
p(t) = 800 + 9t/90 + t^2
You want to know the "rate of change" after 6 hours.
We know that the rate of change is the derivative of P(t) with respect to t; this is

now we want the rate of change when t = 6, then we replace t by 6 in the derivate equation:

so the rate of change after 6 hours is 12.9
where 
If the equation is wrong ( because you write P(t) = 800 1 + 9t 90 + t2, and i don really know how to iterprete it) tellme and we can do the derivate again :D
Answer:
Angle 4
Step-by-step explanation:
theyre alternate interior angles
please mark me brainliest if I’m right!,
Answer:
40°, 95°, 105°, and 160°
Step-by-step explanation:
Let the smallest angle be x.
Measures of the 3 angles can be expressed as:



The sum of all angles in a quadrilateral = 360°.
Therefore, 
Solve for x






The smallest angle = 40°
Plug in the value of x in the earlier stated expressions to find the measure of the other angles:
