Answer:
Therefore the rate of growth of the tree is 33 cm/ yr.
Step-by-step explanation:
Given that,
The height of the tree is
H= 210 +33t
Here H represent the height of tree in cm and t is time in year.
The rate of growth is the first order derivative of the H with respect to time.
i.e The rate of growth
∴H= 210 +33t
Differentiating with respect to t
Therefore the rate of growth of the tree is 33 cm/ yr.
Answer:
x (Fancy Gold fish) = 3
y (Common goldfish) = 29
Step-by-step explanation:
Fancy goldfish x cost $3 each
common goldfish y cost $1 each
Graph: y = 20 + 3x (I'm hoping this is the correct line equation, please do leave a comment below if it's not)
Thus, we graph it by subtitude either the x or y values. (Or you can use just X = 1,2,3).
Now, to find how many of each type of goldfish Tasha can buy. We subtitude the line equation by either using x = 3 or y = 1
Using either values to solve the equation, we get:
x = 3
y = 29
Hope this helps!
