To use the mean value theorem, we know that there exists a c between 1 and -6 such that f'(c) = (f(1) - f(-6))/(1 - (-6)) = (f(1) - f(-6))/7. Since 4 < f'(x) < 8 for all values of x, we know that 4 < f'(c) < 8.
To find the minimum possible value for f(1) - f(-6), we use the smallest possible value for f'(c), which is 4. Therefore, we have:
f'(c) = (f(1) - f(-6))/7
4 = (f(1) - f(-6))/7
28 = f(1) - f(-6)
So the minimum possible value for f(1) - f(-6) is 28.
To find the maximum possible value for f(1) - f(-6), we use the largest possible value for f'(c), which is 8. Therefore, we have:
f'(c) = (f(1) - f(-6))/7
8 = (f(1) - f(-6))/7
56 = f(1) - f(-6)
So the maximum possible value for f(1) - f(-6) is 56.
Therefore, the possible range of values for f(1) - f(-6) is from 28 to 56.
Using the Mean Value Theorem, there exists a value c in the interval (-6, 1) such that f'(c) = (f(1) - f(-6))/(1 - (-6)). Given that 4 < f'(x) < 8 for all values of x, we can apply these bounds to f'(c).
4 < (f(1) - f(-6))/7 < 8
To find the minimum and maximum possible values for f(1) - f(-6), we can solve for this expression in the inequalities:
Minimum possible value:
4 < (f(1) - f(-6))/7
f(1) - f(-6) > 4 * 7
f(1) - f(-6) > 28
Maximum possible value:
(f(1) - f(-6))/7 < 8
f(1) - f(-6) < 8 * 7
f(1) - f(-6) < 56
So, the minimum possible value for f(1) - f(-6) is 28, and the maximum possible value for f(1) - f(-6) is 56.

A company pays $5,000 for equipment. Annual depreciation on the equipment is $500. What is the book value of the equipment at the end of Year 2?
a. $4,000
b. $5,000
c. $6,000
d. $3,000
A company pays $5,000 for equipment. The book value of the equipment at the end of Year 2 will be $4,000.
The book value of an asset can be calculated by subtracting the accumulated depreciation from the initial cost of the asset.
Given:
Initial cost of the equipment = $5,000
Annual depreciation = $500
After Year 1, the accumulated depreciation would be $500.
So, the book value at the end of Year 1 would be:
Book value at the end of Year 1 = Initial cost - Accumulated depreciation
Book value at the end of Year 1 = $5,000 - $500 = $4,500
After Year 2, the accumulated depreciation would be $500 + $500 = $1,000 (since depreciation is $500 per year).
So, the book value at the end of Year 2 would be:
Book value at the end of Year 2 = Initial cost - Accumulated depreciation
Book value at the end of Year 2 = $5,000 - $1,000 = $4,000
Therefore, the book value of the equipment at the end of Year 2 is $4,000. Hence, the correct answer is option a. $4,000.

* You have a dog that can run 5 km/hr. How fast can she run in mi/hr? (i.e. convert the rate to miles per hour) (1.6 km=1mi) DO NOT JUST TYPE THIS INTO A CONVERTER ONLINE. YOU WILL NOT GET THE ANSWER RIGHT. Express your answer as decimal, rounded to the nearest thousandth (three decimal places) in mi/hr - no spaces EXAMPLE: 78.345mi/hr
The dog's running speed of 5 km/hr can be converted to approximately 3.125 mi/hr by multiplying it by the conversion factor of 1 mi/1.6 km. Rounding to the nearest thousandth, the dog can run at about 3.125 mi/hr.
To convert the dog's running speed from kilometers per hour (km/hr) to miles per hour (mi/hr), we need to use the conversion factor of 1.6 km = 1 mi.First, we can convert the dog's speed from km/hr to mi/hr by multiplying it by the conversion factor: 5 km/hr * (1 mi/1.6 km) = 3.125 mi/hr.
However, we need to round the answer to the nearest thousandth (three decimal places). Since the digit after the thousandth place is 5, we round up the thousandth place to obtain the final answer.
Therefore, the dog can run at approximately 3.125 mi/hr.

Step-by-step explanation:

(c) A non-uniform but spherically symmetric charge distribution has a charge density: rho(r)=rho 0
(1−r/R)
rho(r)=0
for r≤R
for r>R
where rho 0
=3Q/πR 3
is a positive constant. Show that the total charge contained in this charge distribution is Q. [4] Show that the electric field in the region r>R is identical to that created by a point charge Q at r=0 [2] Derive an expression for the electric field in the region r≤R. [5]
To show that the total charge contained in the charge distribution is Q, we integrate the charge density over the entire volume. The charge density is given by:
ρ(r) = ρ₀(1 - r/R) for r ≤ R,
ρ(r) = 0 for r > R,
where ρ₀ = 3Q/πR³.
To find the total charge, we integrate ρ(r) over the volume:
Q = ∫ρ(r) dV,
where dV represents the volume element.
Since the charge density is spherically symmetric, we can express dV as dV = 4πr² dr, where r is the radial distance.
The integral becomes:
Q = ∫₀ᴿ ρ₀(1 - r/R) * 4πr² dr.
Evaluating this integral gives:
Q = ρ₀ * 4π * [r³/3 - r⁴/(4R)] from 0 to R.
Simplifying further, we get:
Q = ρ₀ * 4π * [(R³/3) - (R⁴/4R)].
Simplifying the expression inside the parentheses:
Q = ρ₀ * 4π * [(4R³/12) - (R³/4)].
Simplifying once more:
Q = ρ₀ * π * (R³ - R³/3),
Q = ρ₀ * π * (2R³/3),
Q = (3Q/πR³) * π * (2R³/3),
Q = 2Q.
Therefore, the total charge contained in the charge distribution is Q.
To show that the electric field in the region r > R is identical to that created by a point charge Q at r = 0, we can use Gauss's law. Since the charge distribution is spherically symmetric, the electric field outside the distribution can be obtained by considering a Gaussian surface of radius r > R.
By Gauss's law, the electric field through a closed surface is given by:
∮E · dA = (1/ε₀) * Qenc,
where ε₀ is the permittivity of free space, Qenc is the enclosed charge, and the integral is taken over the closed surface.
Since the charge distribution is spherically symmetric, the enclosed charge within the Gaussian surface of radius r is Qenc = Q.
For the Gaussian surface outside the distribution, the electric field is radially directed, and its magnitude is constant on the surface. Hence, E · dA = E * 4πr².
Plugging these values into Gauss's law:
E * 4πr² = (1/ε₀) * Q,
Simplifying:
E = Q / (4πε₀r²).
This is the same expression as the electric field created by a point charge Q at the origin (r = 0).
To derive an expression for the electric field in the region r ≤ R, we can again use Gauss's law. This time we consider a Gaussian surface inside the charge distribution, such that the entire charge Q is enclosed.
The enclosed charge within the Gaussian surface of radius r ≤ R is Qenc = Q.
By Gauss's law, we have:
∮E · dA = (1/ε₀) * Qenc.
Since the charge distribution is spherically symmetric, the electric field is radially directed, and its magnitude is constant on the Gaussian surface. Hence, E · dA = E * 4πr².
Plugging these values into Gauss's law:
E * 4πr² = (1/ε₀) * Q.
Simplifying:
E = Q / (4πε₀r²).

What is the width of a rectangle with a length of 5/6
feet and an area of 2 square feet? Write an equation to show your work.
helpppp PLEASE
The width of the rectangle is 12/5 feet or 2.4 feet.
Let's denote the width of the rectangle as 'w'.
We know that the length of the rectangle is 5/6 feet and the area is 2 square feet.
The formula for the area of a rectangle is:
Area = Length × Width
Plugging in the given values, we have:
2 = (5/6) × w
To find the width, we can solve this equation for 'w'.
Multiplying both sides of the equation by 6/5 (the reciprocal of 5/6), we get:
2 × (6/5) = (5/6) × w × (6/5)
12/5 = w
So, the equation representing the solution is:
w = 12/5

Answer:
( x + 4 )^2 + ( y - 15 )^2 = 1; Option A
Step-by-step explanation:
~ Let us apply the standard circle equation ( x - a )^2 + ( y - b )^2 = r^2, provided r ⇒ radius when centered at point ( a, b ) ~
1. If the center is provided to be ( -4, 15 ) we could substitute this value into the circle equation with variables x and y remaining such:
( x - ( - 4 ) )^2 + ( y - 15)^2 = r^2
2. Simplifying this equation, we have: ( x + 4)^2 + ( y - 15 )^2 = r^2
3. Now by point on the circle, it would be a point on the circumference, to be clear in more mathematical terms. So far we have eliminated two options, with two remain - and each of them has either a radius of 1 or 2. If the point on the circle is ( -4, 16 ) that would mean 1 more than 15, which means that with a radius of 1 ⇒ this point will be on the circle.
Answer: ( x + 4 )^2 + ( y - 15 )^2 = 1
Kite PQRS at the right is concave. If we have PQ = QR = 20, PS= SR= 15, and QS = 7, then what is the area of kite PQRS?
The area of Kite PQRS at the right is concave. If we have PQ = QR = 20, PS= SR= 15, and QS = 7 is 220 square units
How to find the area of kite PQRSFirst, we can find the length of the diagonal PR using the Pythagorean theorem:
PR² = PQ² + QR² = 20² + 20² = 800
PR = sqrt(800) ≈ 28.28
Similarly, we can find the length of the diagonal QS:
QS² = QR² + RS² = 20² + 15² = 625
QS = sqrt(625) = 25
Now, we can split the kite into two triangles, PQS and QRS, and use the formula for the area of a triangle:
area of PQS = (1/2) * PQ * QS = (1/2) * 20 * 7 = 70
area of QRS = (1/2) * QR * RS = (1/2) * 20 * 15 = 150
So the total area of the kite is:
area of PQRS = area of PQS + area of QRS = 70 + 150 = 220

in the expression, you can only subtract 4x - 2x because they have like terms/the same variable.
you cannot add x^2 to 4x because x^2 and x are NOT like terms/the same variable. (If 4x was 4x^2, then you would be able to add them together.

Answer:
angle AED = 70 degrees
angle x = 10 degrees
Step-by-step explanation:
since angle ABD = 110 degrees, major arc AED = 2(110) = 220 degrees
since angle ADB = 40 degrees, minor arc AB = 2(40) = 80 degrees
minor arc BD = 360 - 220 - 80 = 60 degrees
arc AB + arc BD = arc ABD
arc ABD = 80 + 60 = 140 degrees
angle AED = 1/2 (140) = 70 degrees
angle EAD = angle AED because isosceles
arc ED = 2(70) = 140 degrees
arc AE = arc AED - arc ED = 80 degrees
angle x = 1/2(arc AE - arc BD) = 1/2(80 -60) = 10 degrees
