If the volume of a cube increases at rate of 3 cm^3/sec what is the rate of increase of the length of its side ?
Greetings from Brasil...
We know that
V = L³ ⇒ L = ∛V
and
dV/dt = 3cm³/s (volume rate as a function of time)
Let
dL/dV = L' = 1/(3∛V²)
We need dL/dt (side rate as a function of time), so
(dV/dt) . (dL/dV) = dL/dt
then
dL/dt = 3 . [1/(3∛V²)]
dL/dt = 1/∛V²please help me
Here are two expressions whose sum is a new expression, A.
(2x2+5)+(6x□−7)=A
Select all the values that we can put in the box so that A is a polynomial.
Answer:
D, F and G
Step-by-step explanation:
A polynomial must have a negative exponent for the variable term. So we can eliminate A, B and C
Also no fractional exponents so eliminate E
F & G are positive exponents so acceptable
D has the exponent 0 so the term becomes (2x² + 5) + (6x⁰ + 7)
x⁰ = 1 so the expression becomes 2x² + 5 + 6 + 7 = 2x² + 18 which is a polynomial.
If point A is located at (5, –3) and point B is located at (–4, –6). Find AB A B rounded to the nearest tenth.
The distance between the point A and point B is 9.5 units
Distance between two pointsThe formula for calculating the distance between two points is expressed according to the formula shown below;
AB = √(x₂-x₁)²+(y₂-y₁)²
Using the given coordinates points A(5, -3) and B (-4, -6)
Substitute to have:
AB = √(5-(-4))²+(-3-(-6))²
AB = √(5+4)²+(-3+6))²
AB = √81+9
AB = √90
AB = 9.5 units
Hence the distance between the point A and point B is 9.5 units

A Rate is a special kind of ratio that is used to show the comparison of two different units of measurments. a ratio compares the same units
A rate is a ratio because it compares two numbers yet a ratio cannot be a rate because it only compares the same unit.
one common type of rate is per unit time
1 mile has 1600 meters.
distance= 55×1600= 88000m
Time= 1 hour= 3600 second.
speed is euqal to distance upon time.
88000÷ 3600 = 24.4m/s

Under what conditions for the constants a, b, k, and l is (ax by) dx (kx ly) dy = 0 exact? solve the exact ode.
∫dF=F(x,y)=12ax2+bxy+12ℓy2+c=0 is the exact ode.
What is the exact equation?Specifically, an exact equation is a differential equation that can be solved instantly without the aid of any specialized methods. If the result of a straightforward differentiation, a first-order differential equation (of one variable) is referred to as an exact differential or exact differential. The equation
P(x, y)dy/dx + Q(x, y) = 0,
or in the equivalent alternate notation
P(x, y)dy + Q(x, y)dx = 0,
is exact if
∂P(x, y)/∂x = ∂Q(x, y)/∂y
In this instance, a function R(x, y) will exist whose partial x-derivative is Q and partial y-derivative is P, and whose equation R(x, y) = c (where c is constant) will implicitly establish a function y that will satisfy the initial differential equation.
An exact ODE is one where the equation can be written as dF=0 for some F(x,y). Expanding using chain rule, this means an equation of the form
∂1Fdx+∂2Fdy=0
Now if the second partials of F exist and are continuous, they must be equal due to Clairaut. So, given an equation
Mdx+Ndy=0
if we have
∂2M=∂1N
then there is an F such that
M=∂1F, N=∂2F
and hence that equation is exact, and the solution is simply
∫dF=0
We have
M=ax+by⇒∂2M=b
N=kx+ℓy⇒∂1N=k
so to be exact, we must have that b=k .
Then, integrating M and N , we have
F(x,y)=∫Mdx=12ax2+bxy+g(y)
F(x,y)=∫Ndy=bxy+12ℓy2+h(x)
and comparing these two, we can see that
∫dF=F(x,y)=12ax2+bxy+12ℓy2+c=0
is a solution to the equation for any a,b,c,ℓ . You can solve for y by quadratic methods.

A alvin makes 3,200 and spends 701 each month leaving 2,499.
What are average?The average can be calculated by dividing the sum of observations by the number of observations.
Average = Sum of observations/the number of observations
It is Given that alvin has done research and found that he spends an average of $123 on his phone/internet/cable service, $213 on his electric bill, and $270 on his health insurance premium.
Subtract expenditures from earnings;
= 3200 - (178 + 203 + 320)
= 3200 - 701
= 2499
Thus, Grant will have $2,499 after paying these bills each month

The accurately captures a system's gravitational potential energy:
ME = KE + GPE.
What is gravitational potential energy?Gravitational potential energy is the energy that an object possesses or acquires as a result of a change in its position when it is in a gravitational field. In layman's terms, gravitational potential energy is energy that is tied to gravitational force or gravity.
What is the difference between gravitational kinetic energy and potential energy?The energy held in an object due to its height above the ground is known as gravitational potential energy. It is determined by the object's mass, the gravitational acceleration caused by the Earth, and the object's height. Kinetic energy is the energy that an object possesses as a result of its motion.
According to the given data:An object's mechanical energy is equal to the sum of its kinetic energy and potential energy. If ME is mechanical energy and KE is kinetic energy, then PE is its potential energy.
ME = PE + KE
KE = (1/2) mv^2
PE = ME - KE
PE = ME - 1/2(mv²)
PE = ME - 1/2(mv²)

You need to buy a 20-foot length of 15-wide carpet that costs $29.50 per square yard. How much will this cost?
Please include steps!!
The cost of the carpet will be $983.33
Calculating costFrom the question, we are to calculate how much the carpet will cost
From the given information,
The carpet has a length of 20 feet
and a width of 15 feet
First, we will covert the dimension to yard
NOTE: 1 foot = 1/3 yards
Thus,
20 feet = 20/3 yards
and
15 feet = 15/5 yards = 5 yards
Now, we will calculate the area of the carpet
Using the formula,
Area = Length × Width
Area of the carpet = 20/3 × 5 square yard
Area of the carpet = 33.33 square yard
Now, we have that
The carpet costs $29.50 per square yard
∴ The cost of the carpet = 20/3 × 5 × $29.50
The cost of the carpet = $ 983.33
Hence, the cost of the carpet will be $983.33

y(x) = a³ + cos(x) differentiate function using chain rule
Answer: -sinx
the derivative of f(x)f(x) with respect to x is the function f′(x)f′(x) and is defined as,
f’(x) = lim h tends to 0 [ f(x + h) – f(x) / h ]
A function f(x)f(x) is called differentiable at x=ax=a if f′(a)f′(a) exists and f(x)f(x) is called differentiable on an interval if the derivative exists for each point in that interval.
y = cos(x) + a^3
differentiating both sides with respect to x
dy / dx = d/dx (cosx) + d/dx (a^3)
by basic differentiation we know that
d/dx of cosx = -sinx
and differentiation of a constant is 0
therefore,
dy / dx = -sinx + 0
