Since 3 squared is 9 and 4 squared is 16, the square root of 13 will fall somewhere between 3 and 4
The answer to that will be 23
= 20
First, simplify
to
/ Your problem should look like:
= 20
Second, multiply both sides by 8. / Your problem should look like: -5c = 160
Third, divide both sides by -5. / Your problem should look like: c =
Fourth, simplify
to
/ Your problem should look like: c =
Fifth, simplify
to 32. / Your problem should look like: c = -32
Answer:
B) -32
the vertical component of the casting velocity will be reduce to zero at point h by the force of gravity.
If we use the kinematic equation
vf² = vi² +2as
and realize that the final vertical velocity is zero
and the initial vertical velocity is vsinθ
where θ is the angle of cast above the horizon
0 = vsin25 + 2(-9.8)h
h = 0.423v / 19.6
h = 0.02156v
so the missing potential heights and the associated answer velocities are
v = 19 m/s...h = 0.410 m
v = 8.3 m/s...h = 0.179 m
v = 6.9 m/s...h = 0.149 m
v = 8.4 m/s...h = 0.181 m
choose the one that fits the question
or use the method to find the correct velocity based on the actual height reference frame.
Answer:
(a)f(x)=0.8869x
(b)g(x)=143.1126x
(c)g(f(x))=126.9266x
(d)g(f(1000))=126926.6 Yen
Step-by-step explanation:
Given on a particular day
- One U.S. dollar could purchase 0.8869 Euros
- One Euro could purchase 143.1126 yen
(a)If x represents the number of Dollars
Since one can purchase 0.8869 Euro with 1 USD, the function f(x) is a direct relationship where x is dollars and f(x) is in Euros.
(b)If x represents the number of Euros
Since one can purchase 143.1126 yen with 1 Euros, the function g(x) is a direct relationship where x is Euros and g(x) is in Yen.
(c)Given:
g(f(x))=143.1126(0.8869x)
(d)g(f(1000))
- g(f(1000))=126.9266 X 1000 =126926.6 Yen
