Answer:
A
Step-by-step explanation:
If angle a is less then 90 then it’s acute
Answer:
15.7 years
Step-by-step explanation:
we know that
The deforestation is a exponential function of the form
where
y ----> the number of trees still remaining in the forest
x ----> the number of years
a is the initial value (a=500,000 threes)
b is the base
b=100%-4.7%=95.3%=95.3/100=0.953
substitute
The linear equation of planting threes in the region is equal to
using a graphing tool
Solve the system of equations
The intersection point is (15.7,235,110)
see the attached figure
therefore
For x=15.7 years
The number of trees they have planted will be equal to the number of trees still remaining in the forest
So you divide by 2 because there is 2 buildings. You get 760. Now, just take 200 away from one building, and 200 away from the other, and you get 560 for Building A, and 960 from Building B.
Of all it's sides and angles
To covert British thermal units in Joules you need to know that;
1 Joule is equal to 0.00095 British thermal units
Therefore ,
If 1 j is equal to 0.00095 Btu what about 1152Btu
that is
1J x1152 Btu/0.00095 Btu=1212631.579Joules
