The interest rate paid by Scott is 4.25% for the 72 months.
We can determine the simple interest of the given problem by the simple interest formula which is given as :
I=PRT
Where,
I=Interest
P=principal
R=rate in decimal
T=time in years
Converting the given 72 months into years we get time t :
1 year = 12months
72 months / 12months = 6 years
t=6
From the given data
I=8925
P=35000
R=r
T=6
Substituting the above values in the simple interest equation we get:
8925 = 35000*r*6
8925 = 210000*r
divide both sides by 210000
R = 0.0425

slope of YZ Select Choice 1, 0, or -1slope of ZX Select Choice -1, 1, or 0because Select Choice 1(1) = 1, 1(-1) = -1, 1(0) = 0, or 0(-1) =0XY Select Choice is or is not
perpendicular to YZ. Therefore, triangle XYZ Select Choice is not or is a right triangle.
Answer: slope of XY is not perpendicular to YZ. Therefore, triangle XYZ is a right triangle.
Step-by-step explanation:
The slope of a line passing through two points (x1, y1) and (x2, y2) is given by (y2 - y1) / (x2 - x1).
Using this formula, we can find the slopes of the three sides of triangle XYZ:
Slope of XY = (2h - 0) / (2h - 0) = 1
Slope of YZ = (0 - 2h) / (4h - 2h) = -h / h = -1
Slope of ZX = (0 - 0) / (4h - 0) = 0
Therefore, the slope of XY is 1, the slope of YZ is -1, and the slope of ZX is 0.
Since the product of the slopes of two perpendicular lines is -1, we can see that the slope of XY and the slope of YZ are negative reciprocals of each other, which means that they are perpendicular. Therefore, triangle XYZ is a right triangle.

The quadratic equation on the graph can be written as:
y = x² + 6x + 8
Which function is represented byy the graph?Remember that a quadratic equation whose vertex is (h,k) and the leading coefficient is a, can be written as:
y = a*(x - h)² + k
Here we can see that the vertex is at (-3, -1), replacing that we will get:
y = a*(x + 3)² - 1
Now we can also see that it passes through the point (-2, 0), replacing these values we will get:
0 = a*(-2 + 3)² - 1
0 = a - 1
1 = a
Then the quadratic is:
y = (x + 3)² - 1

B.√5∠116.6°
C.[5√∠63.4°]
D.5√∠(63.4°)
1 + 2i in polar form is 5√2∠63.4°.
What is a polar form ?
In mathematics, the polar form is a way of representing complex numbers using their magnitude and angle. A complex number can be represented in the form r(cos θ + i sin θ), where r is the magnitude (or modulus) of the complex number, and θ is its argument (or phase angle). Alternatively, the polar form can be represented in terms of magnitude and angle as r ∠θ, where r is the magnitude and θ is the angle in radians. This form is also known as the exponential form of a complex number. The polar form is useful in calculations involving complex numbers, especially in multiplication and division, where it is often easier to work with the polar form rather than the rectangular form (a + bi).
D. 5√2∠63.4°
To convert a complex number from rectangular form to polar form, we use the following formulas:
r = √(a^2 + b^2)
θ = tan^-1 (b/a)
Where a and b are the real and imaginary parts of the complex number, respectively.
In this case, a = 1 and b = 2, so:
r = √(1^2 + 2^2) = √5
θ = tan^-1 (2/1) = 63.4°
Therefore, 1 + 2i in polar form is 5√2∠63.4°.

D) what is the domain and range of the graphed function?
E) Isabel’s competition, who sells books and no other products, charges a shipping fee of $1.99 per book plus a fixed fee of $3 for each order.

F) graph the function in part e
G) is your graph discrete or continuous? Explain.
The function that expresses f(x) is f(x) = 1.99x + 3, and its graph is continuous.
What is a Continuous Function?A continuous function is one that doesn't have any sudden or unexpected changes in value. It means that if we make small enough changes to its input, the output will also change by a small amount.
We can express the total cost of an order as a function of the number of books sold, x, using the formula:
f(x) = 1.99x + 3
This function takes the number of books sold, multiplies it by the cost per book ($1.99), and adds a fixed fee of $3.
For example, if we sold 3 books, we can use the function to find the total cost:
f(3) = 1.99(3) + 3 = 9.97
This means that selling 3 books would cost $9.97 in total.
The graph of this function is continuous, which means that as we move along the x-axis, the y-values change smoothly and without any sudden jumps.
The term "continuous" refers to a function that can take on any value between two given points and can be broken down into infinitely many fractions and decimals.
In contrast, a discrete function can only take on specific values, usually whole numbers or integers.

Steps for solving t|u prove mt=mu
We may conclude after answering the presented question that As a equation result, we have demonstrated that mt = mu when t | u.
How to solve the problem?Make a note of the definition of t | u. It denotes the existence of an integer k such that u = tk.
To get mt = m, substitute u = tk into mt = mu (tk).
Rewrite m(tk) as (mt)k using the associative property of multiplication.
To get mt = (mt)k, substitute (mt)k for m(tk) in the equation mt = mu.
Multiply both sides by mt. If mt is greater than zero, we obtain 1 = k. If mt is zero, we must also have mu = 0, hence the equation holds.
Since 1 Equals k, we get u = tk = t(1) = t.
We get mt = mt by substituting u = t into the original equation mt = mu.
As a result, we have demonstrated that mt = mu when t | u.

What is the length of side x?
Given:-
A right angled triangle with two angles 60° and 30° is given to us.Length of two shorter sides is x and √10 .To find:-
The value of x .Answer:-
Here since the given triangle is a right angled triangle, we may use the trigonometric ratios . We can see that perpendicular and base are involved in this question whose measures are "x" and "√10" respectively with respect to 60° angle. So here we may use the ratio of tangent as , in any right angled triangle,
[tex]\implies\tan\theta =\dfrac{p}{b} \\[/tex]
and here p = x , and b = √10 . So on substituting the respective values, we have;
[tex]\implies \tan\theta = \dfrac{x}{\sqrt{10}} \\[/tex]
Also the angle here is 60° , so that;
[tex]\implies\tan60^o =\dfrac{x}{\sqrt10} \\[/tex]
The value tan60° is √3 , so we have;
[tex]\implies \sqrt3 =\dfrac{x}{\sqrt10}\\[/tex]
[tex]\implies x =\sqrt{10}\cdot \sqrt{3}\\[/tex]
[tex]\implies x =\sqrt{10\cdot 3} \\[/tex]
[tex]\implies x =\sqrt{30} \\[/tex]
The value of √30 is approximately 5.48 , so that;
[tex]\implies \underline{\underline{\red{\quad x = 5.48\quad }}} \\[/tex]
Therefore the value of x is approximately 5.48 .
Answer:
The length of side x in simplest radical form is [tex]\sqrt{30}[/tex].
Step-by-step explanation:
From inspection of the given right triangle, we can see that the interior angles are 30°, 60° and 90°. Therefore, this triangle is a 30-60-90 triangle.
A 30-60-90 triangle is a special right triangle where the measures of its sides are in the ratio 1 : √3 : 2. Therefore, the formula for the ratio of the sides is b: b√3 : 2b where:
b is the shortest side opposite the 30° angle.b√3 is the side opposite the 60° angle.2b is the longest side (hypotenuse) opposite the right angle.We have been given the side opposite the 30° angle, so:
[tex]\implies b=\sqrt{10}[/tex]
The side labelled "x" is the side opposite the 60° angle, so:
[tex]\implies x=b\sqrt{3}[/tex]
Substitute the found value of b into the equation for x:
[tex]\implies x=\sqrt{10}\sqrt{3}[/tex]
[tex]\textsf{Apply the radical rule:} \quad \sqrt{a}\sqrt{b}=\sqrt{ab}[/tex]
[tex]\implies x=\sqrt{10 \cdot3}[/tex]
[tex]\implies x=\sqrt{30}[/tex]
Therefore, the length of side x in simplest radical form is [tex]\sqrt{30}[/tex].
[tex]\hrulefill[/tex]
We can also calculate the length of side x using the tangent trigonometric ratio:
[tex]\boxed{\tan \theta=\sf \dfrac{O}{A}}[/tex]
where:
θ is the angle.O is the side opposite the angle.A is the side adjacent the angle.From inspection of the given right triangle:
θ = 30°O = √(10)A = xSubstitute these values into the formula:
[tex]\implies \tan 30^{\circ}=\dfrac{\sqrt{10}}{x}[/tex]
[tex]\implies \dfrac{\sqrt{3}}{3}=\dfrac{\sqrt{10}}{x}[/tex]
[tex]\implies x\sqrt{3}=3\sqrt{10}[/tex]
[tex]\implies x=\dfrac{3\sqrt{10}}{\sqrt{3}}[/tex]
Rationalise the denominator by multiplying the numerator and denominator by √3:
[tex]\implies x=\dfrac{3\sqrt{10}}{\sqrt{3}}\cdot \dfrac{\sqrt{3}}{\sqrt{3}}[/tex]
[tex]\implies x=\dfrac{3\sqrt{10}\sqrt{3}}{3}[/tex]
[tex]\implies x=\sqrt{10}\sqrt{3}[/tex]
[tex]\implies x=\sqrt{10\cdot3}[/tex]
[tex]\implies x=\sqrt{30}[/tex]
Therefore, the length of side x in simplest radical form is [tex]\sqrt{30}[/tex].

Of the last 20 trains to arrive at Danville Station, 15 were on time. What is the experimental probability that the next train to arrive will be on time?
Write your answer as a fraction or whole number.
P(on time)=
The experimental probability that the next train to arrive at Danville Station will be on time is 3/4 or 0.75.
What is probability?
Probability is a way to gauge how likely something is to happen. Many things are difficult to forecast with absolute confidence. Using it, we can only make predictions about the likelihood of an event happening, or how likely it is. Probability can range from 0 to 1, with 0 denoting an impossibility and 1 denoting a certainty.
The experimental probability of the next train to arrive at Danville Station being on time is given by the number of on-time trains divided by the total number of trains that arrived -
experimental probability = number of on-time trains / total number of trains
From the information given, we know that out of the last 20 trains to arrive, 15 were on time. Therefore -
number of on-time trains = 15
total number of trains = 20
Substituting these values into the equation, we get -
experimental probability = 15 / 20
Simplifying the fraction, we get -
experimental probability = 3/4
Therefore, the experimental probability value is obtained to be 3/4 or 0.75.

Sally opens a savings account with $9,000 that earns 7% interest per year, not compounded How much interest, to the nearest penny, will Sally earn in 7 years?
Answer: Sally will earn $4,830.00 in interest over 7 years.
Step-by-step explanation:
If the interest is not compounded, then Sally will earn simple interest, which can be calculated using the formula:
I = P * r * t
where:
I = the interest earned
P = the principal amount (initial investment)
r = the annual interest rate (as a decimal)
t = the time period, in years
In this case, we have:
P = $9,000 (the initial deposit)
r = 7% = 0.07 (the annual interest rate)
t = 7 (the number of years)
So, plugging in the values:
I = $9,000 * 0.07 * 7
I = $4,830.00
Therefore, Sally will earn $4,830.00 in interest over 7 years.

Therefore, this group cannot form a triangle.
Given side lengths: 2, 7, 6
⇒ 2 + 7 > 6

A cone has a radius of 6 centimeters and a height of 10 centimeters. What is the volume of the cone in cubic centimeters?
centimeters?
A 480π cm³
B 120π cm³
C 360π cm³
D 60π cm³
The volume of the cone in cubic centimeters in terms of π = 120π cm³. That is option B.
How to calculate the volume of a cone?To calculate the volume of a cone, the formula that is to be used;
Volume = 1/3 πr²h
Where;
Height = 10 centimetres
Radius = 6 centimetres
Volume = 1/3 × π × 6²× 10
= 360π/3
= 120π cm³
Therefore the volume of the cone whose dimensions are given = 120π cm³.

What's the easiest way to define distance?The entire movement of an item, independent of direction, is called distance. Regardless of an object's beginning or finishing position, distance may be defined as the amount of ground it has travelled.
Describe a distance example.As a result, distance is indeed a scalar quantity. The whole path an item has taken can be used to define the distance from it. Think about it this way. If a car drives 5 km east, then turns to head north for 8 km, the final distance driven by the automobile must be 13 km.
The circumference of a semicircle with diameter d is [tex](pi/2)d[/tex]. Therefore, the length of each semicircular section is [tex](pi/2) * 36 = 18pi[/tex].
The total distance around the track is the sum of the lengths of the two straight sections and the two semicircular sections.
Distance around track [tex]= 2(100 yards) + 2(18pi yards)[/tex]
[tex]= 200 yards + 36pi yards[/tex]
[tex]= 312.57 yards[/tex] (rounded to two decimal places)
Therefore, the distance around the entire track is approximately [tex]312.57[/tex]yards.
