Answer:
yes since it grows at a constant rate at 7.5 feet/5 days so it should be proportional if you treat it as an algebraic equation and solve for the rate of 1 day's growth but that gives an assumption that no factors would affect the growth and it'll always grow at that exact rate

Answer:
(0,5)
Step-by-step explanation:
We know that x will equal 0
because y=5 is a horizontal line running through 5 on the y axis, we know that the y intercept will be (0,5)
Answer:
17 cm
Step-by-step explanation:
By Pythagoras Theorem
Answer:
a = 1
b = - 1
Explanation:
To know the values of a and b, we need to solve the following equation:
So, replacing cos(-π/4) by √2/2 and sin(-π/4) by -√2/2, we get:
Applying the distributive property:
Therefore, we can complete the equation as:
It means that a = 1 and b = - 1.
