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:
CS = 4
Step-by-step explanation:
From the figure below;
Triangle ABC is similar to triangle RSC
Therefore, the ratio of the corresponding sides in the two triangles is equal;
That is;
In this case, CR = 2 , RA = 3 and BC = 10 we are required to determine CS
But; 
AC=CR + RA
= 5
Assuming CS is y, then
Therefore, CS is 4
Answer:
4/5?
Step-by-step explanation:
Because If you have 5/5 and take away 1/5 from it then that leaves you with 4/5
Answer:
4
Step-by-step explanation:
As discussed in the section on galaxy classifications, Hubble found four distinct types of galaxies: elliptical, spiral, spiral barred and irregular. Although there are different types, we also learned that each galaxy contains the same elements, but these are arranged differently for each type.
Answer:
0.4375
Step-by-step explanation:
Number of shots attempted by Farah = 84
Number of shots made by Farah = 28
So,
Shots made out of shots attempted will be Equal to
= 0.4375
Thus,
Number of shots made out of number of shots attempted for farah in hockey match equals to 0.4375 .
