Answer
D=13
The equation is simple but I can do it.
F(x) = x^2
g(x) = f(3x) = (3x)^2 = 9x^2
Because the coefficient is 9 (greater than 1) it should be a narrow function like option A.
Answer:
10%
Step-by-step explanation:
Amount of salt in 90g of water = 10g
Total weight of solution (salt + water) = (10g + 90g) = 100g
=> Total weight of salt in 100g of solution = 10g
Hence, Percentage of salt in this solution is given by:
This corresponds to 10%
So the percentage of salt in the solution = 10%
Similarly, percentage of water in the solution = = 90%
Answer:
The smaller angle is 12 and the larger angle is 168
Step-by-step explanation:
Let call the measure of the random angle a. There is a angle that is 14 times of that and supplementary to that the random angle. So that is represented by
Supplementary Angles add up to 180 degrees so let set up an equation
which equal after you combine like with like
Divide 15 by both sides and a=12 and the so smaller angle is 12 and the larger angle is 168
