Answer: f(x) = x9h(x)
h(-1) = 2
h'(-1) = 5
We need to find h(x) first. Once we have h(x), we can find the derivative of f(x). Then evaluate the derivate when x = -1.
We know that derivative is the slope of the tangent line. In this case, the slope of the line tangent to h(x) at x=-1 is 5.
h(-1) = 2 has a coordinate point of (-1, 2).
2 = 5(-1) + b
2 = -5 + b
7 = b
h(x) = 5x + 7 -----> equation of the tangent line
f(x) = x9(5x + 7)
f(x) = 5x10 + 7x9
Take the derivative of f(x).
f'(x) = 50x9 + 63x8
f'(-1) = 50(-1)9 + 63(-1)8
f'(-1) = -50 + 63
f'(-1) = 13

Its between the first or the third but i think its the third
Answer:
Step-by-step explanation:
1. Angular speed
The angular speed ω is the angle θ swept out by the satellite in a given time t.
2. Linear speed
The formula for the linear speed v is
v = rω, where
r = the distance from the centre of the Earth = 6378 km + 1250 km = 7628 km
Step-by-step explanation:
We are given two Triangles and we need to prove them congruent . In ∆AOC and ∆BOD , we have
Therefore by AAS congruent condition we can say that ,
Hence Proved!
Answer:
<h2>The answer is 112°</h2>
Step-by-step explanation:
Let the third interior angle be x
Since it's a triangle , all it's interior angles sum up to 180°
To find the third interior angle , add up the two of the equivalent angles that's 34 and subtract it from 180
We have
x + 34 + 34 = 180
x + 68 = 180
x = 180 - 68
We have the final answer as
<h3>112°</h3>
Hope this helps you
