Answer:
No, because he needs to make a 18 by 12 base. Not enough wood, (area)..... square inches
F(x)= x² + 5, is just a parabola shfited upwards by 5 units, so, is a smooth graph and no abrupt edges, so from 0 to 3, is indeed differentiable and continuous. So Rolle's theorem applies, let's check for "c" by simply setting its variable to 0, bear in mind that, looking for "c" in this context, is really just looking for a critical point, since we're just looking where f'(c) = 0, and is a horizontal tangent line.
300 represents the initial amount of the substance, the amount present at t=0.
0.5 is the fraction of substance remaining at the end of each year. The fact that this number is 1/2 indicates the half-life of the substance is 1 year.
Answer:
y = 20x + 5
Step-by-step explanation:
X = Y/20 - 1/4
In this type of expression you will first of all find the LCM of the right hand side
x = y - 5/ 20
the next thing to do is to cross multiply
we have,
20x = y - 5
dont forget we are to solve for y in the equation, so to solve for y we have
20x + 5 = y
therefore y will be expressed in terms of x as written below
y = 20x + 5
Let c represent candy and s soda.
2c+s=8
c+s=5.5
Solving the pair of simultaneous equations by eliminating s,
c=2.5
Representing the value of c in equation 1;
5+s=8
s=3
So, a box of Candy costs 2.5 and a soda costs 3
