Solve for m. m/2 - squareroot 5 = 3
Answer:
We can start by isolating the variable term on one side of the equation and moving all other terms to the other side.
First, we'll add the square root of 5 to both sides of the equation:
m/2 - sqrt(5) + sqrt(5) = 3 + sqrt(5)
Simplifying:
m/2 = 3 + sqrt(5)
Next, we'll multiply both sides of the equation by 2:
m = 2(3 + sqrt(5))
Simplifying:
m = 6 + 2sqrt(5)
Therefore, the value of m is 6 + 2sqrt(5).

The slope of the polar curve at θ = π/4 is 24. Therefore, option D is correct.
To find the slope of the polar curve r = 6cos(2θ) - 5 at θ = π/4, we need to find the derivative of r with respect to θ, and then substitute θ = π/4 into the resulting expression.
Using the chain rule of differentiation, we have:
dr/dθ = dr/d(cos(2θ)) * d(cos(2θ))/dθ
To find the first derivative, we can use the power rule of differentiation:
dr/d(cos(2θ)) = -12sin(2θ)
To find the second derivative, we can use the chain rule again:
d(cos(2θ))/dθ = -2sin(2θ)
Substituting these into the expression for dr/dθ, we get:
dr/dθ = -12sin(2θ) * (-2sin(2θ)) = 24sin^2(2θ)
Now, substituting θ = π/4, we get:
dr/dθ|θ=π/4 = 24sin^2(π/2) = 24
The slope of the polar curve at θ = π/4 is therefore 24.

We have,
An axon is a long, tubelike structure that extends from a neuron's cell body.
It is a specialized fiber that carries electrical impulses, known as action potentials, away from the cell body and towards the axon terminals.
Axons are covered by a fatty substance called myelin, which insulates and protects the axon and helps to speed up the transmission of signals.
At the end of the axon, there are small branches called axon terminals, which release chemicals called neurotransmitters into the synapse, the small gap between the axon terminals and the dendrites of the next neuron in the circuit.
This allows the electrical signal to be converted into a chemical signal and transmitted to the next neuron, continuing the chain of communication in the nervous system.

use the equation 1/5 +s =32/40
The required solution to the equation 1/5 + s = 32/40 is s = 3/5.
To solve the equation 1/5 + s = 32/40 for s, we can begin by subtracting 1/5 from both sides to isolate s:
1/5 + s = 32/40
s = 32/40 - 1/5
We need a common denominator to combine the fractions on the right side of the equation. The least common multiple of 5 and 40 is 40, so we can convert both fractions to have a denominator of 40:
s = (32/40) - (8/40)
s = 24/40
Simplifying the fraction 24/40 by dividing both the numerator and denominator by their greatest common factor, which is 8, we get:
s = 3/5
Therefore, the solution to the equation 1/5 + s = 32/40 is s = 3/5.

two is superior, both waxes are applied to the floor surfaces in each of a sample of 25 homes. It is
known that the proportion of people that prefer A is 0.4 while the rest prefer brand B. Find the
probability that at least 8 homes would state a preference for brand B.
The probability of at least 8 homes would prefer brand B compare to compare A is given by 0.672.
Sample size 'n'= 25
Proportion of people prefer brand A = 0.4
This implies ,
Proportion of people prefer brand B 'p' = 1 - 0.4
= 0.6
Using the binomial distribution.
Let X be the number of homes that prefer brand B out of the 25 homes surveyed.
Then X follows a binomial distribution with parameters n = 25 and p = 0.6
Probability that at least 8 homes would state a preference for brand B. expressed as,
P(X ≥ 8) = 1 - P(X < 8)
Using the binomial distribution, compute P(X < 8) as follows,
P(X < 8) = Σ [²⁵Cₓ] × 0.6ˣ × 0.4²⁵⁻ˣ, for x = 0, 1, 2, ..., 7
where ²⁵Cₓ is the binomial coefficient which represents the number of ways to choose k homes out of 25.

You deposit $500 in an account that earns simple interest at an annual rate of 4%. How much money is in the account after 6 years?
Answer:
The formula for simple interest is:
I = P * r * t
Where:
I = Interest earned
P = Principal amount (initial amount deposited)
r = Annual interest rate (as a decimal)
t = Time in years
Using the given values, we have:
P = $500
r = 0.04 (4% expressed as a decimal)
t = 6 years
I = P * r * t
I = $500 * 0.04 * 6
I = $120
So the interest earned after 6 years is $120. To find the total amount of money in the account, we add the interest to the principal:
Total = P + I
Total = $500 + $120
Total = $620
Therefore, there will be $620 in the account after 6 years.

nearest hundredth when necessary.
22 in
17 in
19 in
35 in
20.3 in
The surface area of the figure = 2733.3 sq. in.
First we fine the surface area of the top surface of the figure.
The top surface is an rectangle with length = 19 in. and width = 17 in
Using the formula for the area of rectangle, the area of top face would be,
A₁ = 19 × 17
A₁ = 323 sq. in.
The slant face of the figure is a rectangle with length = 22 in. and width = 17 in
Using the formula for the area of rectangle, the area of slant surface of the figure would be,
A₂ = 22 × 17
A₂ = 374 sq. in.
There are two parallel trapezoidal surface of the figure with bases 35 in. and 19 in. respectively.
The height of the trapezoid = 20.3 in.
Using the formula for that area of trapezoid, the area of two trapezoidal surface of the figure would be,
A₃ = 2 × (sum of lengths two bases/2) × height
A₃ = 2 × (35 + 19/2) × 20.3
A₃ = 1096.2 sq. in.
The area of the bottom surface would be,
A₄ = 35 × 17
A₄ = 595 sq. in.
The area of right surface would be,
A₅ = 20.3 × 17
A₅ = 345.1 sq. in.
So, the total surface area would be,
A = A₁ + A₂ + A₃ + A₄ + A₅
A = 323 + 374 + 1096.2 + 595 + 345.1
A = 2733.3 sq. in.
Therefore, the surface area of the figure = 2733.3 sq. in.
