Answer:
To find the maximum of a function in ax^2 + bx + c form, you can use the formula: maximum = c - (b^2 / 4a).
In this question, a = -16, b = 180, and c = 63.
Maximum = 63 - (180^2/4(-16))
Maximum = 569.25
Finally, rounding this to the nearest tenth of a foot, the final answer is 569.3 ft.

Answer:
y = -2/3x + 4
Step-by-step explanation:
2x + 3y = 12
3y = -2x+12
y = -2/3x + 12/3
y= -2/3x + 4
5÷(4-3)×9-2
= 5÷1×9-2
= 5 × 9 - 2
= 43
You must solve the bracket first.After that,solve the multiplication and division,followed by addition and substraction if any.That's the theory to solve the right step
Answer:

Step-by-step explanation:
Given:
Number of feathers = 
Number of caps = 
Number of feathers in each cap = 3
Now, solving by setting up a proportion.
1 cap has 3 feathers. 'c' caps has 'f' feathers.
This gives,

Solving by cross multiplication, we get:

Therefore, the equation representing the number of feathers 'f' Erica needs to make 'c' caps is given as:

Answer:
x < 4
Step-by-step explanation:
Step 1: Simplify both sides of the inequality.
Step 2: Subtract x from both sides.
Step 3: Subtract 6 from both sides.
Step 4: Multiply both sides by 4/(-1).
