sry if my answer is wrong but I think it is the square root of nine
Answer:
rate of change = -32 feet/second
Step-by-step explanation:
h(t) = 64 – 16t2
t = time (seconds)
Look at the start of time where t = 0
h(t) = 64 - 16 * (0) * 2 = 64 feet
Then look at the specified time where t = 1.25 seconds
h(t) = 64 - 16 * (1.25sec) * 2 = 24 feet
rate of change = rate of change y / rate of change x
x = time, y = height
rate of change = (24 - 64) / (1.25 - 0) = -32 feet/second
hours did it take for oil to cover the area = 592
The correct option is B.
<h3>What is geometrical figure?</h3>
Geometrical shapes are the shapes that depict the shapes of various items. Various figures have two dimensions, while others have three. Only the x and y axes are used for two-dimensional figures, whereas the x, y, and z axes are used for three-dimensional shapes.
<h3>According to the given information:</h3>
Given,
Area = 11000m²
Radius = .10m/h
We know the area of the circle:
Area = πr²
The relation between parameter:
Area = πr²
11000 = 3.14 * (0.10t)²
Dividing both side by 3.14
11000/3.14 = (3.14 * (0.10t)²)/3.14
by solving this we get:
(.10t)² = 3503.184
.10t = 59.187
dividing both side by 0.10
t = 59.187/.10
t = 591.877
t = 592
hours did it take for oil to cover the area = 592

Answer:
a = -7 and b = 1. The constant term is 4
Step-by-step explanation:
In standard form, this equation is -7x^2 + x + 4 = 0
The coefficients are a = -7 and b = 1. The constant term is 4.
