Explanation:
Solving (4): 0.84554 as a fraction
The above number is to 5 decimal places, so the fraction equivalent is:
Divide numerator and denominator by 2
Solving (5):
The midpoint, M is calculated as follows:
Where
The distance, D is calculated using:
Solving (1): The expression for f(x) is not clear. So, I'll make use of:
Substitute each value of the domain in
The range is:
Solving (2):
Shape: Open Cylinder
The surface area is calculated as:
Solving (3):
The value of a is not clear. So, I'll assume that a is a
Given that
Find
Substitute 3a for b
Absolute value of 4a is 4a. So,
Solving (9):
Given
--- Principal
--- Rate
--- Time in years
The amount (A) is calculated as follows:
Hence, the amount at the end of 2 years is:
Line the outside of the cup with the tinfoil. Then put the cotton balls inside. Finally, line the cotton balls with the tinfoil and smush it all together.
Answer: 12Mg/h
Explanation:
Let the spring is compressed by a distance x,before the lift stops,then
Mg(h+x)= 1/2 kx^2 ............... 1
Kx - Mg = M ( 5g ) ............ 2
Make x the subject in equation 2
Kx = 5Mg + Mg
Kx = 6Mg
x = 6Mg/k ............ 3
Put equation 3 into 1
Mg ( h + x ) = 1/2 kx^2
Mgh + Mgx = 1/2kx^2
Mgh + Mg × 6Mg/k = 1/2k × ( 6Mg/k )^2
Mgh + Mg× 6Mg/k = 1/2k 36M^2g^2/ k^2
h =18Mg/k - 6Mg/h
K = 12Mg/h
