Answer:
Height of the taller building is 63.5ft
Step-by-step explanation:
Kindly find attached rough sketch of the problem for your reference.
Let the small building be A and the taller building be B
From the sketch the two buildings form a right angle triangle
We can solve for x which is the height of the taller building relative to the small building using
SOH CAH TOA
Applying TOA we have
Tan θ= opposite/adjacent
Tan 42°= x/35
x= Tan 42*35
x= 0.9*35
x= 31.5ft
Hence the height of the taller building is = x+height of small building = 31.5+32= 63.5ft
Answer:
The reason is because we assume that each week have the same weight and replacing we got:
And the best option would be:
D. 221.25
Step-by-step explanation:
For this case we have the following data given
Week 1 2 3 4
Minutes 190 163 327 205
For this case we can find the mean with the following formula:
The reason is because we assume that each week have the same weight and replacing we got:
And the best option would be:
D. 221.25
Answer:
1) Let's consider the first case with the number 0 the oppose is also 0 and we have that 0-0=0 so then applies
2) Now let's consider any real number a no matter positive or negative we will have that:
Or in the other case:
So then we can conclude that the expression is a general rule and is true
Step-by-step explanation:
For this case we can verify if the following expression is true or false:
The sum of x and it’s opposite is always zero?
If we want to proof this we need to show that for any number is true.
