1) tan 41°= 30cm divide by y cm
y= 30 divide by tan-1 41°
For calculating the mean, you want to add up all of the numbers then divide by how many numbers there are. So you'd do:
5+10+12+4+6+11+13+5 then divide that by 8
The answer to your question is: 8.25
So all you need to do if find the min of the function:
f(x)=0.04x^3-4x^2-176x
f'(x)=0.12x^2-8x-176
The only zero for this is x=84.105 <---first
Plug this into f(x) to get f(84.105)=-19300 <---second
Answer:
The number line on the top right
Step-by-step explanation:
Her solution should be
2x - 14 ≤ 8
x ≤ 22
x ≤ 11
'x' is less than or equal to 11.
