For the first point, remember this simple rule: every exponential function always returns
when evaluated at
. In fact,
for every possible base
.
So, we can see that the graph of the exponential passes through the point where
appears to be between 1 and 2. So, the only feasible option would be
, because it passes throught the point
because
.
The other functions are wrong because:
would pass through
, which would be between 0 and 1 on the y axis
would pass through
, which would be between 2 and 3 on the y axis
would pass through
, which would be between 0 and 1 on the y axis
As for the second question, you simply have to plug in the values: the function
means that you have to choose an input, x, and use it as exponent for 7. So, if you choose x=2, it means that you have to give exponent 2 to 7, i.e. you replace the x with the specific value, 2.
So, the expression becomes
Answer:
The question does not have value of height (in the image)
the barn in shape of a cuboid with a half cylinder.
volume of barn = volume of cuboid + volume of cylinder/2
here,
b=6 m
l=10 m
so, 2r=6. thus, r=3,
which approximately,
141.3+60h
for storing all of the hay
141.3+60h≥600
h≥7.644
so..
check if h is less than 7.644, he would not be able to store all of the barn.
