The statement suppose <span>that r varies directly with s and inversely with t is best represented as:
r </span>α s/t
To make it into equality, we insert a proportionality constant, k:
r = ks/t
Using the initial conditions, we solve for k.
r = ks/t
<span>r = 2 when s = 3 and t = 12
2 = k(3)/12
k = 8
Thus, when </span><span>s = 5 and t = 4,
</span>
r = 8(5)/4
r = 10 -----> OPTION C
Answer:
So M is the midpoint of RS lmbo
Step-by-step explanation:
What you have here are lengths of two equal segments, expressed as different algebraic expressions.
you just set those two expressions equal, and solve for x. Then plug that x into EITHER of the two expressions, to get the equal lengths of RM & MS.
divide 4480 by 40
And for the 1760 ft multiply that twice
-5+0.5x= 13
Add 5 to both sides
0.5x= 18
Multiply both sides by 2
x= 36
Final answer: x=36
1) You know the height of the bird from the observer is the same as the height of the plane to tower. We also know that the angle of depression is same as the angle of elevation.
So we will use the tangent function to find the value of x.
tan 23 = 5000 / x
x = 5000 / tan 23
x = 11779
You're answer will be 11779 feet
2) We will use the sine function.
sin 35 = 17,000 / x
x = 17,000 / sin 35
x = 29638.6
So the answer would be approximately 29639
