1.Given the two points :
(xi; yi) = (-3;2) and
(x2;y2) = (6;5)
We can find the slope m as follows :
M = (y2-yi)/(x2-xi)
= (5 -2) /( 6-(-3)
= (3)/(6+3 )
=3 /9
=1/3
This means that the slope m = 1/3
Which steps can be used to solve for the value of y?
2/3 (y+57)=178
A. Divide both sides by 2/3, then subtract 57 from both sides.
B. Subtract 57 from both sides, then divide both sides by 2/3.
C. Multiply both sides by 2/3, then subtract 57 from both sides.
D. Subtract 2/3 from both sides, then subtract 57 from both sides.
Answer:
A. Divide both sides by 2/3, then subtract 57 from both sides.
Step-by-step explanation:
You want to know the steps to solve 2/3(y +57) = 178 for y.
StepsThe variable has 57 added to it, and the sum is multiplied by 2/3. To solve for y, you need to undo these operations in reverse order.
First, you divide by 2/3.
y +57 = 267
Then you subtract 57.

find the volume of the solid formed by revolving the region bounded by the graphs of y = 4x - x^2 and f(x) = x^2 from [0,2] about the... a) x-axis.
Answer:
\(v = \frac{32\pi}{3}\)
or
\(v=33.52\)
Step-by-step explanation:
Given
\(f(x) = 4x - x^2\)
\(g(x) = x^2\)
\([a,b] = [0,2]\)
Required
The volume of the solid formed
Rotating about the x-axis.
Using the washer method to calculate the volume, we have:
\(\int dv = \int\limit^b_a \pi(f(x)^2 - g(x)^2) dx\)
Integrate
\(v = \int\limit^b_a \pi(f(x)^2 - g(x)^2)\ dx\)
\(v = \pi \int\limit^b_a (f(x)^2 - g(x)^2)\ dx\)
Substitute values for a, b, f(x) and g(x)
\(v = \pi \int\limit^2_0 ((4x - x^2)^2 - (x^2)^2)\ dx\)
Evaluate the exponents
\(v = \pi \int\limit^2_0 (16x^2 - 4x^3 - 4x^3 + x^4 - x^4)\ dx\)
Simplify like terms
\(v = \pi \int\limit^2_0 (16x^2 - 8x^3 )\ dx\)
Factor out 8
\(v = 8\pi \int\limit^2_0 (2x^2 - x^3 )\ dx\)
Integrate
\(v = 8\pi [ \frac{2x^{2+1}}{2+1} - \frac{x^{3+1}}{3+1} ]|\limit^2_0\)
\(v = 8\pi [ \frac{2x^{3}}{3} - \frac{x^{4}}{4} ]|\limit^2_0\)
Substitute 2 and 0 for x, respectively
\(v = 8\pi ([ \frac{2*2^{3}}{3} - \frac{2^{4}}{4} ] - [ \frac{2*0^{3}}{3} - \frac{0^{4}}{4} ])\)
\(v = 8\pi ([ \frac{2*2^{3}}{3} - \frac{2^{4}}{4} ] - [ 0 - 0])\)
\(v = 8\pi [ \frac{2*2^{3}}{3} - \frac{2^{4}}{4} ]\)
\(v = 8\pi [ \frac{16}{3} - \frac{16}{4} ]\)
Take LCM
\(v = 8\pi [ \frac{16*4- 16 * 3}{12}]\)
\(v = 8\pi [ \frac{64- 48}{12}]\)
\(v = 8\pi * \frac{16}{12}\)
Simplify
\(v = 8\pi * \frac{4}{3}\)
\(v = \frac{32\pi}{3}\)
or
\(v=\frac{32}{3} * \frac{22}{7}\)
\(v=\frac{32*22}{3*7}\)
\(v=\frac{704}{21}\)
\(v=33.52\)

The measure of an angle is 1°. Find the measure of the complement.
The measure of the complement of a 1-degree angle is 89 degrees.
The complement of an angle is defined as the angle that, when added to the given angle, results in a sum of 90 degrees. To find the measure of the complement of a 1-degree angle, we need to determine the angle that, when added to 1 degree, equals 90 degrees.
Let's denote the measure of the complement as x degrees. According to the definition, we can set up the equation:
1 degree + x degrees = 90 degrees.
To solve for x, we need to isolate it on one side of the equation. By subtracting 1 degree from both sides, we have:
x degrees = 90 degrees - 1 degree.
Simplifying the right side, we get:
x degrees = 89 degrees.
In summary, when an angle measures 1 degree, its complement measures 89 degrees. Complementary angles are pairs of angles that add up to 90 degrees. In this case, since the given angle measures only 1 degree, its complement is significantly larger, nearly forming a right angle. The concept of complementary angles is fundamental in geometry and can be applied to various problems involving angles and their relationships.

Step-by-step explanation:
The population of mosquitoes in a certain area increases at a rate proportional to the current population, and in the absence of other factors, the population doubles each week. There are 200,000 mosquitoes in the area initially, and predators (e.g. birds, bats) eat 20,000 mosquitoes/day. Determine the population of mosquitoes in the area at any given time.
So far, I have used the equation, P = P0 e^-kt The population of mosquitoes in a certain area inc where P0=200,000 and P(7)=400,000 (I figured time should be measured in days since you are given the number of mosquitoes eaten per day) to solve for k:
400,000 = 200,00 e^-k(7) >> K=-ln(2)/7=-.099
Using that, I figured I should put that into the differential equation (change in population = birthrate - deathrate)
dp/dt = kP - 20,00t ---> dp/dt = -099P - 20,000t
I thought I knew how to solve this and everything, but once I got an answer and plugged in different times, the model says the population decreases, which doesn't seem to make sense. So please check my reasoning up to this point and show the solution so I can check mine.
The equation you used is correct, but the differential equation does not include the growth rate. The growth rate is proportional to the current population, so the differential equation should look like this: dp/dt = kP - 20,000t
dp/dt = kP - 20,000t , Where k is the growth rate. To solve this equation, we can use the separation of variables: dp/P = kdt - 20,000tdt
Integrating both sides, we get:
ln|P| = kt - 20,000t^2/2 + C, Where C is the integration constant. To find C, we can use the initial population of 200,000:
ln|200,000| = -0.099t - 20,000t^2/2 + C
=>C = ln|200,000| + 0.099t + 20,000t^2/2 .Therefore, the population of mosquitoes at any given time t is:
P = 200,000e^(-0.099t - 20,000t^2/2 + ln|200,000| + 0.099t + 20,000t^2/2) = 200,000e^(ln|200,000|) = 200,000

Step-by-step explanation:
A quality control expert at LIFE batteries wants to test their new batteries. The design engineer claims they have a variance of 2916 with a mean life of 518 minutes.
If the claim is true, in a sample of 81 batteries, what is the probability that the mean battery life would be less than 526.4 minutes? Round your answer to four decimal places.
The probability that the mean battery life would be greater than 526.4 minutes if in a sample of 81 batteries having a variance of, 2916 and a mean life of 518 minutes is 0.0808.
What is probability?The ratio of good outcomes to all possible outcomes of an event is known as probability. A lot of successful results for an experimental with 'n' results can be represented by the symbol x.
Given:
The variance = 2916,
The mean life of a battery, m = 518 min,
The total number of samples, n = 81
Calculate the probability of a mean battery life of lower than 526.4 minutes by the following formula,
z = x - m / (σ / √ n)
Here, x is the expected value, σ is the deviation, and z is the probability.
Substitute the values,
z = 526.4 - 518 / (54 / √81) [σ = √ variance = √2916 = 54]
z = 1.4
Consult the cumulative standard normal table
P (z < 526.4) = 0.9192,
But we know that
P (z > 526.4) = 1 - P (z < 526.4)
P (z > 526.4) = 1 - 0.9192 = 0.0808
Therefore, The probability that the mean battery life would be greater than 526.4 minutes if in a sample of 81 batteries having a variance of, 2916 and a mean life of 518 minutes is 0.0808.

Step-by-step explanation:
\(3x + 2 < 4x - 3 \\ = 3x - 4x < - 3 - 2 \\ = - x < - 5 \\ = x > 5\)
Solve the equation
\(3 \csc ^{2} (x) = 5 - 5 \cot(x) \)
, given all values of x in the interval
\( - \pi \leqslant x \leqslant \pi\)
To solve the equation \(3 \csc ^{2} (x) = 5 - 5 \cot(x) \), we will start by rewriting the right-hand side of the equation using the identity \(\cot x = \frac{1}{\tan x}\):
\(3 \csc ^{2} (x) = 5 - 5 \frac{1}{\tan(x)}\)
Next, we will use the identity \(\csc^2 x = \frac{1}{\sin^2 x}\) to rewrite the left-hand side of the equation:
\(\frac{3}{\sin ^{2} (x)} = 5 - 5 \frac{1}{\tan(x)}\)
Now, we will use the identity \(\sin^2 x + \cos^2 x = 1\) to rewrite the denominator on the left-hand side:
\(\frac{3}{1 - \cos^2 x} = 5 - 5 \frac{1}{\tan(x)}\)
Next, we will use the identity \(\tan^2 x = \sec^2 x - 1\) to rewrite the fraction on the right-hand side:
\(\frac{3}{1 - \cos^2 x} = 5 - 5 (\sec^2 x - 1)\)
Now, we will distribute the negative sign on the right-hand side:
\(\frac{3}{1 - \cos^2 x} = 5 - 5 \sec^2 x + 5\)
Combining like terms on the right-hand side gives us:
\(\frac{3}{1 - \cos^2 x} = 10 - 5 \sec^2 x\)
Adding 5 to both sides and then dividing both sides by 10 gives us:
\(\frac{3 + 5}{10} = 1 - \frac{5}{10} \sec^2 x\)
Simplifying the left-hand side gives us:
\(\frac{8}{10} = 1 - \frac{5}{10} \sec^2 x\)
Multiplying both sides by 10 and rearranging terms gives us:
\(\sec^2 x = \frac{10 - 8}{5} = \frac{2}{5}\)
Taking the square root of both sides gives us:
\(\sec x = \pm \frac{\sqrt{2}}{\sqrt{5}}\)
To find the values of x that satisfy the equation, we need to find the values of x in the interval \(-\pi \leqslant x \leqslant \pi\) that give us a positive value for \(\sec x\). Since the secant function is positive for all values of x in the interval \(0 \leqslant x < \pi\), all values of x in this interval will satisfy the equation.
Therefore, the solution to the equation is \(x \in \left[ 0, \pi \right)\).

Felicity’s dog eats no more than two cups of dog food per day. Felicity’s dog eats at least one-quarter cup more than one-half of the amount Martin’s dog eats. If the amount of food that Martin’s dog eats is represented by using m, which inequality represents the situation?
The inequality that represents the situation is (1/2)m + (1/4) ≤ F ≤ 2.
What are Linear Inequalities?
Linear inequalities are mathematical statements that involve two expressions connected by an inequality symbol (such as <, >, ≤, or ≥) and describe a relationship between these expressions that is not necessarily equal. They are often used to represent constraints or conditions in real-world problems involving variables.
Let's start by defining a variable to represent the amount of food that Martin's dog eats: m.
According to the problem, Felicity's dog eats at least one-quarter cup more than one-half of the amount Martin's dog eats. One-half of the amount Martin's dog eats is (1/2)m, and one-quarter cup more than that is (1/2)m + (1/4).
So, the amount of food that Felicity's dog eats can be represented by the inequality:
F ≤ (1/2)m + (1/4)
where F is the amount of food that Felicity's dog eats.
However, we also know that Felicity's dog eats no more than two cups of dog food per day. Therefore, we can add another constraint to the inequality:
F ≤ 2
Putting these two constraints together, we get:
(1/2)m + (1/4) ≤ F ≤ 2
or, in a simplified form:
(1/2)m + (1/4) ≤ F ≤ 2
So, the inequality that represents the situation is (1/2)m + (1/4) ≤ F ≤ 2.

So if we know the perimeter of the circle we can find it's radius using the formula for perimeter:
\(p = 2\pi(r)\)
So we can solve for radius:
\(r = \frac{10.71}{2\pi} \)
Then we can plug this radius into the formula for the area of a circle:
\(a = \pi {r}^{2} \)
\(a = \pi( \frac{10.71}{2\pi} ) ^{2} \)
Then it only wants a quarter of that area so we divide that value by 4 which upon simplification becomes the answer:

To find:
Area of quarter circle
Step-by-step explanation:
First we need to calculate the radius of quarter circle:
Let the radius of quarter circle be 'r'
\(Perimeter \: of \: quarter \: circle = \frac{\pi r}{2} + 2r\)
\( \implies 10.71 = \frac{\pi r}{2} + 2r \\ \\ \implies 10.71 = \frac{\pi r}{2} +2r \frac{2}{2} \\ \\ \implies 10.71 = \frac{\pi r}{2} + \frac{4r}{2} \\ \\ \implies 10.71 = \frac{\pi r + 4r}{2} \\ \\ \implies 10.71 \times 2 = \pi r + 4r \\ \\ \implies 21.42 = \pi r + 4r \\ \\ \implies 21.42 = (\pi + 4)r \\ \\ \implies 21.42 = (3.14 + 4)r \\ \\ \implies 21.42 = 7.14r \\ \\ \implies 7.14r = 21.42 \\ \\ \implies r = \frac{21.42}{7.14} \\ \\ \implies r = 3 \: ft\)

What is the scale factor of this dilation?
Answer:
5/3
Step-by-step explanation:
on both sides we can see that the orginal length of 3 increased to five
therfore if we multiply 3 by 3/5 we get five which means the scale factor is 5/3
Follow the guided instructions below to rotate the figure 90° counter-clockwise about
the origin.
Draw a circle centered at the center of rotation, such that one of the vertices
of the figure is on the circle.

When rotated 90 degrees, counterclockwise direction the new coordinates will result in the attached image.
What are the new coordinates?The old coordinate where were rotated are:
A(-5,8)
B (-1, 7)
C(-3, 5)
D(-4, 2)
To rotate a point counterclockwise about the origin, we switch the x and y coordinates and change the sign of the new x -coordinate.
The new coordinates are after 90 degrees, counterclockwise are
A' = (-8, -5)
B' = (-7, -1)
C' = (-5, -3)
D' = (-2, -4)
