I think after the 9th bounce it will lose 90% of its max height
times 40 by 0.9 which will give you 36
then take 36 away from 40 leaving you with 4.
answer = 4ft
Answer:
yes
Step-by-step explanation:
A relation is a function in which for each input there is only one output.
In a relation, y is a function of x.
Now we look at the mapping
For input 6, -1 is the output
for input -1, 2 is the output
for input 4, 3 is the output
for input 0, 3 is the output
For each input , there is an output. Input is not repeating. Input is occurring only once.
So this relation is a function.
Answer:
2 > 1
Step-by-step explanation:
-6 < -3 to -6/-3 > -3/-3 to 2 > 1
When dividing or multiplying by a negative, flip the inequality sign.
Answer:
The unit vector u is (-5/√29) i - (2/√29) j
Step-by-step explanation:
* Lets revise the meaning of unit vector
- The unit vector is the vector ÷ the magnitude of the vector
- If the vector w = xi + yj
- Its magnitude IwI = √(x² + y²) ⇒ the length of the vector w
- The unit vector u in the direction of w is u = w/IwI
- The unit vector u = (xi + yj)/√(x² + y²)
- The unit vector u = [x/√(x² + y²)] i + [y/√(x² + y²)] j
* Now lets solve the problem
∵ v = -5i - 2j
∴ IvI = √[(-5)² +(-2)²] = √[25 + 4] = √29
- The unit vector u = v/IvI
∴ u = (-5i - 2j)/√29 ⇒ spilt the terms
∴ u = (-5/√29) i - (2/√29) j
* The unit vector u is (-5/√29) i - (2/√29) j
A=p(1+r)^t
13400=10000(1+r)^6
Solve to find the interest rate
r=((13,400÷10,000)^(1÷6)−1)×100
r=4.99%=5%
