Volume of a rectangular prism is l*h*w
1.2*3*4.5= 16.2
The answer is 16.2 cubic inches
The required value of y is 2645 / 77 when x = 77.
Step-by-step explanation:
1. Let's check the information given to answer:
if y varies inversely as x, and y = 23 when x = 115. Find y when x=77
2. What is y when x = 77?
As the statement "y varies inversely as x" translates into y = k/x
If we let y = 23 and x = 115, the constant of variation becomes
23 = k ÷ 115
k = 23 × 115
k = 2645
Thus the specification equation is y = 2645 ÷ x . Now, letting x = 77, we obtain
y = 2645 ÷ x
y = 2645 ÷ 77
<u>So, The required value of y = 2645 / 77 when x = 77</u>

Answer:
Hopefully this is the answer but I got
6.25 or 6 ¼
Step-by-step explanation:
5 × 10⁴ = 5 × 10000= 50,000
8 ×10³ = 8 × 1000= 8000
50,000/8000 = 6.25 or 6 1/4
Large company (50k) is 6.25 times bigger than smaller(8k)
Answer:
The minimum y-value is
or 
Step-by-step explanation:
we have

This is the equation of a vertical parabola open up
The vertex is the minimum y-value on the graph
Convert the equation into vertex form
Group terms that contain the same variable, and move the constant to the opposite side of the equation

Factor the leading coefficient

Complete the square. Remember to balance the equation by adding the same constants to each side


Rewrite as perfect squares

------> equation in vertex form
The vertex is the point (-0.5,-7.75)
therefore
The minimum is the point (-0.5,-7.75)
The minimum y-value is
