Answer:
3) m = -3/2
4) m = 3/2
5) m = 5/3
6) m = 7/3
7) m = -3
8) m = 7/3
Step-by-step explanation:
Slope = rise/run or (y2 - y1) / (x2 - x1)
3/ ( -4, 0) ( -2, -3)
The y decrease by 3, and the x increase by 2, so the slope is
m = -3/2
4/ (2,0) (0, -3)
The y decrease by 3, and the x decrease by 2, so the slope is
m = -3/-2 = 3/2
5/ (-1,2) (-4, -3)
The y decrease by 5, and the x decrease by 3, so the slope is
m = -5/-3 = 5/3
6/ (4,3) (1, -4)
The y decrease by 7, and the x decrease by 3, so the slope is
m = -7/-3 = 7/3
7/ (1,2) (3, -4)
The y decrease by 6, and the x increase by 2, so the slope is
m = -6/2 = -3
8/ (0,3) (-3, -4)
The y decrease by 7, and the x decrease by 3, so the slope is
m = -7/-3 = 7/3
Given the recursive formula shown, what are the first 4 terms of the sequence?
The first 4 terms of the sequence by the given recursive formula is found as: 6 , 13, 20, 27.
Explain about the recursive formula?A straightforward illustration of either a recursive function is the factorial, which multiplies a number by itself while lowering it slowly. Recursive functions can refer to a wide variety of self-referential looping functions, such as those whereby n = n + 1 assuming an operational range.For the stated question:
f(n) :
f(1) = 6
f(n) = f(n - 1) + 7, if n > 1.
Thus,
First term, n = 1: f(1) = 6
Second term, n = 2:
f(2) = f(2 - 1) + 7
f(2) = f(1) + 7
f(2) = 6 + 7
f(2) = 13
Third term: n = 3.
f(3) = f(3 - 1) + 7
f(3) = f(2) + 7
f(3) = 13 + 7
f(3) = 20
Fourth term: n = 4.
f(4) = f(4 - 1) + 7
f(4) = f(3) + 7
f(4) = 20 + 7
f(4) = 27
Thus, the first 4 terms of the sequence by the given recursive formula is found as: 6 , 13, 20, 27.

A graph is defined by the equation y²(2 - x) = x³. find the x- or y-value of each point where the slope of the original equation is undefined.
The value of x and y for which the graph has undefined slope is y = 0 or x = 2
Given y²(2 - x) = x³
We are asked to determine the point on the curve which has an undefined slope.
Undefined slope means dy/dx = ∞
Now, y²(2 - x) = x³
Differentiating both sides
2y dy/dx (2-x) - y² = 3x²
dy/dx = (3x² + y²)/2y(2-x)
So, (3x² + y²)/2y(2-x) = ∞
For this 2y(2-x) = 0
We can see that the possible cases y = 0 or x = 2
Hence for y = 0 or x = 2, the slope of the graph is undefined.

solve the following initial value problems for y(t) by antidifferentiation or by aseparation of variables: dy dt = y t cos( ) y; y(0) = 2
y(t) = 2e^(sin(t) + t) is the antiderivative of the function dy/dt = y cos(t) + y, and satisfies the initial condition y(0) = 2.
This is a first-order linear differential equation, which can be solved by the separation of variables. To do so, we can start by writing:
dy/dt = y cos(t) + y
We can divide both sides by y:
dy/dt / y = cos(t) + 1
Now, we can integrate both sides with respect to t, using the property that d(ln y)/dt = 1/y:
∫(dy/dt / y) dt = ∫(cos(t) + 1) dt
ln|y| = sin(t) + t + C
Where C is the constant of integration. To find its value, we can use the initial condition y(0) = 2:
ln|2| = sin(0) + 0 + C
C = ln|2|
Therefore, the solution of the initial value problem is:
y(t) = 2e^(sin(t) + t)
This is the antiderivative of the function dy/dt = y cos(t) + y and satisfies the initial condition y(0) = 2.

which describes the pedestrian crossing sign shown?the sign is a trapezoid because exactly one pair of opposite sides is parallel.the sign is a parallelogram because both pairs of opposite sides are parallel.
The pedestrian crossing sign is a parallelogram because both pairs of opposite sides are parallel. The Second option is Correct.
A parallelogram is a quadrilateral that has two pairs of parallel sides, meaning that both sets of opposite sides are parallel. This is opposed to a trapezoid, which has only one pair of parallel sides. The pedestrian crossing sign is typically in the shape of a parallelogram, with the top and bottom sides being parallel, and the sides slanting towards each other to form a point at the top.
This design helps the sign to be easily visible from a distance and clearly recognizable as a pedestrian crossing sign. The parallel sides of the sign are an important characteristic that helps drivers and pedestrians to identify and understand the meaning of the sign.

Mr Houston bought a new car for £18500 in July 2010.
Its value depreciated by 15% in the first year, 18% in the
second year and 25% in the third year.
By how much had its initial price fallen by July 2013?
The percentage decrease from first to third year is; 47.725%
How to calculate percentage decrease?To find the percentage decrease, work out the difference (decrease) between the two numbers you are comparing. Thereafter, divide the decrease by the original number and then multiply the answer by 100.
Amount of car in 2010 = £18500
It depreciated by 15% in the first year. Thus;
Amount after first year = (100% - 15%) * 18500
= £15725
It depreciated by 18% in the second year. Thus;
Amount after second year = (100% - 18%) * 15725
= £12,894.5
It depreciated by 25% in the third year. Thus;
Amount after third year = (100% - 25%) * 12,894.5
= £9,670.875
Thus;
Decrease from first to third year = (18500 - 9670.875)/18500 * 100%

Practice 7-3 Constructing Bisectors (PLEASE HELP)
Therefore , the solution of the given problem of angle bisector comes out to be each measurement will be equivalent to 30 degrees,
What is an Angle Bisector?A bisector exists for each angle. Additionally, it is the symmetry line that connects an angle's two arms, triangle whose construction facilitates the creation of smaller angles.
Here,
A 30° angle, for example, might be called for. A 60° angle can be made, and it can then be divided, to accomplish this.
The concept of an angle bisector is used to construct angles such as 90 degrees, 45 degrees, 15 degrees, and others.
Examples :
What is each angle's measurement if an angle bisector divides an angle of 80 degrees?
The answer is that 80 degrees is the measure of an angle.
It is common knowledge that the angle is divided into two equal pieces by the angle bisector.
Consequently, 80 degrees is divided into two equal portions, let's call x.
Hence,
x + x = 80°
2x = 80°
x = 80°/2
x = 40°.
The second option is ineffective since it would result in A' being positioned at (-5, 2) after translation A 3 up and 1 left (5, -2).
The third option: spinning A in a clockwise direction 90 degrees places it at (-1, 4), then reflecting it across the y-axis places it at (1, 4).
In the fourth option, A is rotated 90 degrees counterclockwise, putting it at (1, -4), and it is reflected across the x-axis, putting it at (1, 4).
The fifth option is to rotate A 180 degrees, which positions it at (-3, -4), after translating 3 down & 1 right (3, 4). B(-5, -5) (-5, -5) Translated results in (-4, -8), and rotated results in (4, 8). Translation of C(-3, -4) results in (-2, -7), and rotation results in (2, 7).

What is the absolute minimum value of y =-cos(x) - sin(x) on the closed interval [0,π/2]? Justify your answer
The absolute minimum value of y =-cos(x) - sin(x) on the closed interval [0, π/2] is [tex]-\sqrt{2}[/tex]
Consider equation,
y = -cos(x) - sin(x)
Let y = f(x)
Differentiate the function f(x) = -cos(x) - sin(x) with respect to x.
f'(x) = -(-sin(x)) - cos(x)
f'(x) = sin(x) - cos(x)
For f'(x) = 0,
sin(x) - cos(x) = 0
sin(x) = cos(x)
sin(x)/cos(x) = 1
tan(x) = 1 ..............(tan(θ) = sin(θ)/cos(θ))
x = π/4
For above value of x, the value of function would be,
f(π/4) = -cos(π/4) - sin(π/4)
f(π/4) = [tex]-\frac{1}{\sqrt{2} } -\frac{1}{\sqrt{2} }[/tex]
f(π/4) = [tex]-\sqrt{2}[/tex]
f(0) = -cos(0) - sin(0)
f(0) = -1

a triangle has an area of 16 in2, and two of the sides of the tri- angle have lengths 5 in. and 7 in. find the angle included by these two sides.
The angle included by these two sides is (c^2 - 74) / (-70).
What is triangle ?
A triangle is a polygon with three edges and three vertices. It is one of the basic shapes in geometry. A triangle with vertices A, B, and C is denoted triangle ABC.
The area of a triangle can be found using the formula:
Area = (1/2) * b * h,
where b is the length of the base and h is the height of the triangle.
Since two of the sides have lengths 5 in and 7 in, we can assume that they are the base and the height of the triangle, respectively. Setting b = 5 in and h = 7 in, we can find the area:
Area = (1/2) * 5 in * 7 in = (1/2) * 35 in^2 = 16 in^2.
This means that the height of the triangle is 7 in and the base is 5 in. To find the angle included by these two sides, we can use the Law of Cosines:
c^2 = a^2 + b^2 - 2ab * cos(C),
where a and b are the lengths of the sides and C is the angle included by these two sides.
Since a = 5 in and b = 7 in, we can find the angle C:
c^2 = a^2 + b^2 - 2ab * cos(C)
c^2 = 5^2 + 7^2 - 2 * 5 * 7 * cos(C)
c^2 = 25 + 49 - 70 * cos(C)
c^2 = 74 - 70 * cos(C)
So , The angle included by these two sides is (c^2 - 74) / (-70).

The approximate energy requirement for the car when driven at 95 km/h is 789.47 kcal/km.
We have,
If a car averages 38 km/gal when driven at 95 km/h, we can calculate the fuel consumption in gallons per kilometer (gal/km).
Fuel consumption (gal/km) = 1 / (average fuel efficiency in km/gal)
Fuel consumption (gal/km) = 1 / 38
Now, to determine the energy requirement in kcal per kilometer (kcal/km), we multiply the fuel consumption by the energy released per gallon of gasoline:
Energy requirement (kcal/km) = Fuel consumption (gal/km) * Energy released per gallon (kcal/gal)
Energy requirement (kcal/km) = (1 / 38) * (3 x 10^4 kcal/gal)
Now,
Fuel consumption (gal/km) = 1 / 38
Energy requirement (kcal/km) = (1 / 38) * (3 x 10^4 kcal/gal)
Energy requirement (kcal/km) = (1 / 38) * (3 x 10^4 kcal/gal)

Alicia will have £2,238.93 in her account after 10 years if she invests £2130 in a 0.5% account.
What is percent?A % is a relative figure that represents the hundredth part of any amount. One percent (symbolized 1%) is one hundredth part; consequently, 100 percent denotes the complete amount and 200 percent defines twice the supplied amount. percentage. Mathematics percentile is a related topic. A percentage is a fraction of a whole represented as a number between 0 and 100. Nothing is zero percent, everything is 100 percent, half of everything is fifty percent, and nothing is zero percent. To calculate a percentage, divide the share of the total by the total and multiply by 100.
Here,
principal=£2,130.00
rate=0.5%
time=10 years
Compound interest earned=£108.93

A more detailed version of Theorem I says that, if the function f (x, y) is continuous near the point (a, b), then at least one solution of the differential equation y' = f(x, y) exist on some open interval I containing the point x = a and moreover, that if in addition the partial derivative partial differential f/partial differential y is continuous near (a, b), then this solution is unique on some (perhaps smaller) interval J. In Problems 11 through 20, determine whether existence of at least one solution of the given initial value problem is thereby guaranteed and, if so, whether uniqueness of that solution is guaranteed. dy/dx = 2x^2y^2: y(1) = -1 dy/dx = x ln y: y(1) = 1 dy/dx = cubicroot y: y(0) = 1 dy/dx = cubicroot y: y(0) = 0 dy/dx = Squareroot x- y: y(1) = 2 dy/dx = Squareroot x - y: y(2) = 2 dy/dx = Squareroot x - y: y(2) = 1 y dy/dx = x - 1: y(0) = 1 y dy/dx = x - 1: y(1) = 0 dy/dx = ln(1 + y^2): y(0) = 0 dy/dx = x^2 - y^2: y(0) = 1

Step-by-step explanation:
buckley farms decides to increase the mean weight of each bag of chips so that only 5% of the bags have weights that are less than 16 ounces. assuming that the standard deviation remains 0.12 ounce, what mean weight should buckley farms use?
Assuming that the standard deviation remains 0.12 ounces, so 16.251 ounces mean weight should Buckley Farms use.
The total weight of each bag follows an approximately normal distribution with a mean of 16.15 ounces and a standard deviation of 0.12 ounces.
Mean (μ) = 16.15
Standard deviation, (σ) = 0.12
n = 6
Buckley Farms decides to increase the mean weight of each bag of chips so that only 5%(0.05) of the bags have weights that are less than 16 ounces. So
P(X > x) = 0.05
P[(X - μ)/(σ/√n) > (x - μ)/(σ/√n)] = 0.05
1 - P(Z ≤ z) = 0.05
Subtract 1 on both side , we get
P(Z ≤ z) = 0.95
z = 1.96
(x' - μ)/(σ/√n) = 1.645
Now putting the value
(x' - 16.15)/(0.15/√6) = 1.645
(x' - 16.15)/(0.15/2.45) = 1.645
(x' - 16.15)/(0.0612) = 1.645
Multiply by 0.0612 on both side, we get
x' - 16.15 = 0.100674
Add 16.15 on both side, we get
x' = 16.251
