Oil is spilled onto a kitchen floor. The area covered by the oil at time t is given by the function A, where A(t) is measured in square centimeters and t
is measured in seconds. Which of the following gives the rate at which the area covered by the oil is changing at time t=10?
Answer:
did you ever fine out the answer to this lol
Step-by-step explanation:
Oil is spilled onto a kitchen floor. The area covered by the oil at time t is given by the function A, where A(t) is measured in square centimeters and t
is measured in seconds. The rate at which the area covered by the oil is changing at time t = 10 is A'(10).
Given that:
The area covered by the oil at time t = A(t)To determine the rate at which the area covered by the oil is changing with time, we need to differentiate A(t) with respect to time t.
∴
By differentiation:
[tex]\mathbf{\dfrac{dA}{dt} =A'(t)}[/tex]
The rate at which the area covered with oil is changing is t = 10∴
[tex]\mathbf{\dfrac{dA}{dt} \Big| _{t=10}=A'(t)\Big|_{t=10}}[/tex]
[tex]\mathbf{\dfrac{dA}{dt} =A'(10)}[/tex]
Therefore, we can conclude that the rate at which the area covered by the oil is changing at time t=10 is A'(10).

What is the equation of the line in point slope form given a slope of -3 and a point of (-2,-5)?
Answer:
y = -3x - 11
Step-by-step explanation:
Use the given slope and point in the point-slope equation. Solving this will give us the y-intercept equation.
Point-slope formula: y - y = m(x - x)
Plug in the slope and point
y - (-5) = -3(x - (-2))
Subtracting negatives will make them positive. Multiply out the -3 to what is in the parentheses.
y + 5 = -3x - 6
Subtract the 5 from both sides
y = -3x - 11
The equation of the line is y = -3x - 11

What is Trigonometry?Trigonometry is a branch of mathematics that studies relationships between side lengths and angles of triangles.
Given,
Jay walks 3 blocks north and then 4 blocks east from his home if he walks straight back home.
We have to use pythagorean theorem in finding distance
As given in the attachment, Let AB= 3
BC=4

To find AC we use pythagorean theorem
AC²=AB²+BC²
AC²=3²+4²
AC²=9+16
AC²=25
Take square root on both sides.

Answer:
569
Step-by-step explanation:
Raia’s monthly car payments is $8160.
What is simple interest?Simple Interest (S.I.) is the method of calculating the interest amount for a particular principal amount of money at some rate of interest.
Given that, Raia purchases a new car for $32,000 and finances it with a 6-year simple interest loan at a rate of 4.25%
We need to find;
What are Raia’s monthly car payments?
So, SI = PRT / 100
P = Principal amount
r = rate
T = time
So,
SI = 32000 x 4.25 x 6 / 100
= 8160
Hence, Raia’s monthly car payments is $8160.

9514 1404 393
Answer:
an infinite number of ways
Step-by-step explanation:
The transformation involves a series of reflections, rotations, and translations. Any reflection and translation can be described an infinite number of ways, depending on what you choose for the line of reflection (and how many reflections you choose), and how far you do each translation. Similarly, any rotation can described an infinite number of ways, depending on the amount of rotation and the chosen center point.
So, the answer to the question asked is, "You can describe the movement of the furniture an infinite number of ways."
__
One way to describe it is this:
The upper chair was translated to the right, then reflected* across the horizontal centerline. The couch was rotated 90° about the center of the room and translated upward. The coffee table was rotated -90° about its center and translated to the right.
__
* As a practical matter, a piece of furniture cannot be reflected. It can only be rotated or translated. However, the pillows in the upper chair are moved from the left arm to the right arm, so the appearance is that of a reflection. One might say the chair was rotated 180°, and the pillows were translated.

Answer:
h = 18( I might be wrong though)
Step-by-step explanation:
If BE and ED are perpendicular, that means this angle is supplementary.
BEF = 3h-12
FED = 2h - 23
BEF + FED = 90
3h-12 + 2h - 23 = 90
5h - 35 = 90
5h = 90

An expression that has a value of 31
The arithmetic operation can be defined as the operation in which we do the addition of numbers, subtraction, multiplication, and division. It has a basic four operators that is +, -, ×, and ÷.
A) 3√25 + 7-5
= 3(5) + 7 - 5
= 15 + 7 - 5
= 17
B) (3√25) +7-5
= (3x5) +7-5
= 15 +7-5
= 17
C) 3√25+ (7-5)
= 3x5 +2
= 17
D) 3(√25 + 7) - 5
= 3(5+7) - 5
= 36 - 5
