Answer:
D: 1600cm^2
Step-by-step explanation:
Answer:
25000 mg.
Step-by-step explanation:
There are 1000 mg per gram. If we multiply 1000*25 we will get 25000 mg of sugar.
Let the initial price be 100. Price after 1 month is 101.9. common ratio is r = 101.9/100 = 1.019
After 12 months, the price will be:
A1 x r ^n-1
= 101.9 * (1.019)^12-1
= 101.9 * 1.019^11= 125.34
So the yearly increase would be: 125.34 – 100 = 25.34
Therefore, the yearly price rise percentage is 25.34/100 x 100 = 25.34%
Let's look at the picture, let's imagine that the gray line is the perimeter fence and that the red OR the blue is the one dividing it. We can see that the blue line is longer than the red one, so it will be advantageous, to have a bigger area, to have the dividing fence the smallest possible.
Let's say then that the width (W) is bigger (or equal) to the length (L), so we have:
The area is W*L, so we have
this function is a parabola facing down, its zeros are 0 and 80, therefore its maximum is when L=40
hence, L=40 and W=(240-120)/2=60
It will be a rectangle, measuring 60x40 and the divinding fence will be 40
Answer:
D. G(x) = 7x2
Step-by-step explanation:
Given a function f(x), the function kf(x) is stretched by a factor of k. In this case, if we stretch the function f(x) = x^2 by a factor of 7, the new function is going to be:
g(x) = 7x^2. Therefore, the correct option is option D.
