Below is an excerpt from a home loan contract.

“The sum of the principal of the loan and all applicable interest will be divided into 360 monthly payments according to the amortization schedule.

The Buyer shall make each monthly payment by the first day of the month it is due. A payment not received by the first day of the month it is due will be considered delinquent. A payment not received by the fifteenth day of the month it is due will be subject to a late charge of $75.00. If a payment is not received by the last day of the month it is due, the Buyer and transaction shall be reported to the appropriate credit agencies.

In the event of delinquency, the Buyer may divide any payment not received into not more than three equal installments to be included on the next consecutive monthly payments. Notification of the Buyer’s intent to do so must be made by written letter or phone call to the phone number and address listed below within one business week of delinquency.”

According to the contract, which of the following is not a responsibility of the buyer?
a.
Pay the monthly payment on time.
b.
Notify the bank if a payment is going to be late.
c.
Pay an additional $75.00 with a payment made after the 15th day of the month it was due.
d.
Notify the bank of his or her intent to split a late payment into three partial payments.

Are you sure that one of the variables is v and not y?

Answer:

C. 3 times

Step-by-step explanation:

If cube a has an edge length of 2 and cube b has an edge length of 6,the volume of cube b than cube a is 3 times greater.

For this case we have that by definition, the volume of a cube is given by:

[tex]V = l ^ 3[/tex]

Where:

l: It's the side of the cube

Cube A:

[tex]l = 2\\V = 2 ^ 3 = 8 \ units ^ 3[/tex]

Cube B:

[tex]l = 6\\V = 6 ^ 3 = 216 \ units ^ 3[/tex]

We divide:

[tex]\frac {216} {8} = 27[/tex]

Thus, the volume of cube B is 27 times larger than that of cube A.

Answer:

All real numbers [tex](-\infty, \infty)[/tex]

Step-by-step explanation:

First we solve the following inequality

[tex]6b < 36[/tex]

Divide by 6 both sides of the inequality

[tex]b<\frac{36}{6}\\\\b<6[/tex]

The set of solutions is:

[tex](-\infty, 6)[/tex]

Now we solve the following inequality

[tex]2b + 12 > 6[/tex]

Subtract 12 on both sides of the inequality

[tex]2b + 12-12 > 6-12[/tex]

[tex]2b> -6[/tex]

Divide by 2 on both sides of the inequality

[tex]\frac{2}{2}b> -\frac{6}{2}[/tex]

[tex]b> -3[/tex]

The set of solutions is:

[tex](-3, \infty)[/tex]

Finally, the set of solutions for composite inequality is:

[tex](-\infty, 6)[/tex]  ∪ [tex](-3, \infty)[/tex]

This is: All real numbers [tex](-\infty, \infty)[/tex]

Answer:

Option B, C and D are correct choices.

Step-by-step explanation:

We have been given an equation [tex]3.5+1.2(6.3-7x)=9.38[/tex]. We are asked to choose the steps that are involved in solving the equation.

Let us solve the equation.

Using distributive property [tex]a(b+c)=ab+ac[/tex], we will distribute 1.2 to 6.3 and [tex]-7x[/tex].

[tex]3.5+1.2*6.3-1.2*7x=9.38[/tex]

[tex]3.5+7.56-8.4x=9.38[/tex]

Therefore, option B is the correct choice.

Now, we will combine like terms.

[tex]11.06-8.4x=9.38[/tex]

Therefore, option C is the correct choice.

Now, we will subtract 11.06 from both sides of our equation.

[tex]11.06-11.06-8.4x=9.38-11.06[/tex]

[tex]-8.4x=-1.68[/tex]

Therefore, option D is the correct choice.

Now, to solve for x, we need to divide both sides of our equation by [tex]-8.4[/tex]

[tex]\frac{-8.4x}{-8.4}=\frac{-1.68}{-8.4}[/tex]

[tex]x=0.2[/tex]

Answer:

Distribute 1.2 to 6.3 and –7x;

Combine 3.5 and 7.56.

Subtract 11.06 from both sides.

Step-by-step explanation:

To answer this expression. Let's follow P.E.M.D.A. order, the acronym for  PArenthesis, Exponents, Multiplication, Division and Addends.  So distributing the factor 1.2 to the parenthesis content:

[tex]3.5+1.2(6.3-7x)=9.38 \\3.5+7.56-8.4x=9.38[/tex]

Then adding the 3.5 to 7.56 to simplify it:

[tex]3.5+7.56-8.4x=9.38\\\11.06-8.4x=9.38[/tex]

The next step in order to isolate is to subtract 11.06 from both sides

[tex]11.06-8.4x-11.06=9.38-11.06[/tex]

Then it goes on

[tex]-8.4x=-1.68\:\:*(-1)\\8.4x=1.68\Rightarrow x=\frac{1.68}{8.4}\Rightarrow x=\frac{1}{5}\\S=\{ {\frac{1}{5}\}[/tex]

Answer:

First case The coefficient of the squared term is 4

Second case The coefficient of the squared term is 1/16

Step-by-step explanation:

I will analyze two cases

First case (vertical parabola open upward)

we know that

The equation of a vertical parabola in vertex form is equal to

[tex]y=a(x-h)^{2}+k[/tex]

where

a is the coefficient of the squared term

(h,k) is the vertex

we have

(h,k)=(-5,-2)

substitute

[tex]y=a(x+5)^{2}-2[/tex]

Find the value of a

Remember that

when the x-value is -4, the y-value is 2.

substitute

For x=-4, y=2

[tex]2=a(-4+5)^{2}-2[/tex]

[tex]2=a(1)-2[/tex]

[tex]a=2+2=4[/tex]

the equation is equal to

[tex]y=4(x+5)^{2}-2[/tex]

therefore

The coefficient of the squared term is 4

Second case (horizontal parabola open to the right)

we know that

The equation of a horizontal parabola in vertex form is equal to

[tex]x=a(y-k)^{2}+h[/tex]

where

a is the coefficient of the squared term

(h,k) is the vertex

we have

(h,k)=(-5,-2)

substitute

[tex]x=a(y+2)^{2}-5[/tex]

Find the value of a

Remember that

when the x-value is -4, the y-value is 2.

substitute

For x=-4, y=2

[tex]-4=a(2+2)^{2}-5[/tex]

[tex]-4=a(4)^{2}-5[/tex]

[tex]-4+5=a(16)[/tex]

[tex]a=1/16[/tex]

the equation is equal to

[tex]x=(1/16)(y+2)^{2}-5[/tex]

therefore

The coefficient of the squared term is 1/16

Answer:

The red point (-4 , -6)

Step-by-step explanation:

* Lets revise the complex number

- The complex number z = a + bi, where a is the real part and b is the

  imaginary part

- The real part represented by the x-axis and the imaginary part

  represented by the y-axis

- The value of i is √(-1)

- The complex conjugate of a complex number is the number with an

 equal real part and an imaginary part equal in magnitude but opposite

 in sign

- Ex: the conjugate of a + bi is a - bi

* Lets solve the problem

∵ A is an complex number

∵ The x-coordinate of A is -4 and the y-coordinate of it is 6

∵ The x-axis is the real axis and y-axis is the imaginary axis

∴ A = -4 + 6i

∵ The conjugate numbers are equal in real part and the imaginary

  part equal in magnitude and different in sign

∴ The conjugate of A = -4 - 6i

- From the graph The red point (-4 , -6) represents the complex

 conjugate of point A

Answer:

c = 6t + 19.60

Step-by-step explanation:

   Let t = the time in hours for which Beth rented the bike. Then  

       6t = the rental cost for the bike and

$19.60 = the up-front cost

The expression for the total cost (c) is

c = 6t + 19.60

The expression for the total cost is C = 19.60 + 6t. According to the given statements, time t is the variable term.

An expression is the combination of variables, coefficients, and constants. These are separated by operators like addition or subtraction. Each combination is called a term.

Given that,

Beth rented a bike from Julia's Bikes.

It cost $19.60 plus $6 per hour.

So, here the variable is time because as the time increases the cost also increases.

Consider time = t and the total cost = C

Then, the expression that represents the given statements is

C = 19.60 + 6t

∴ The expression is C = 19.60 + 6t.

1st and 2nd quadrants

Step-by-step explanation:

You have sine is positive since it is 4/5.

Sine is the y-coordinate.

On the coordinate plane y is positive in the 1st and 2nd quadrants.

The values of θ that could terminate when sin θ = 4/5 are in the first and second quadrants. In the first quadrant, both the sine and cosine values are positive, while in the second quadrant, only the sine value is positive.

To find the quadrants where θ could terminate when sin θ = 4/5, we need to examine the values of sin θ in each quadrant. The sine function is positive in the first and second quadrants so that θ could terminate in either of these quadrants. In the first quadrant, the sine and cosine values are positive, while in the second quadrant, only the sine value is positive.

Step-by-step explanation:

we know that

The approximate average rate of change is equal to

[tex]\frac{f(8)-f(3)}{8-3}[/tex]

[tex]\frac{f(8)-f(3)}{5}[/tex]

we have

[tex]f(x)=0.01(2^{x})[/tex]

Find f(8)

For x=8

[tex]f(8)=0.01(2^{8})=2.56[/tex]

Find f(3)

For x=3

[tex]f(8)=0.01(2^{3})=0.08[/tex]

Find the approximate average rate of change

[tex]\frac{f(8)-f(3)}{5}[/tex]

substitute

[tex]\frac{2.56-0.08}{5}=0.496[/tex]

Answer: A, 0.496

Step-by-step explanation:

To find the difference, you need to raise the base, 2, to each number since x represents the days.

Raise 2 to the power of 3:

2^3 = 8

multiply by 0.01

0.01 * 8 = 0.08

That is the growth of day three.

Now do the same with the 8

Raise 2 to the power of 8

2^8 = 256

Now multiply that by 0.01

0.01 * 256 = 2.56

Now use this formula: f(b) - f(a)/b - a

2.56 - 0.08/8 - 3

Subtract 0.08 from 2.56

2.56 - 0.08 = 2.48

Subtract 3 from 8

8 - 3 = 5

Now divide: 2.48/5 = 0.496

0.496 is the average rate of change between day 3 and day 8. Also I got 100 on the test so I know the answer :))

The value of the product (3 - 21) * (3 + 21) is -432, obtained by applying the distributive property.

To find the value of the product (3 - 21) * (3 + 21), we can use the distributive property or the difference of squares identity. Here's how it works:

(3 - 21) * (3 + 21) = (3 - 21) * [(3) + (21)]  (Apply the distributive property)

Now, let's calculate each part:

1. (3 - 21) = -18

2. (3 + 21) = 24

Now, we multiply these results together:

-18 * 24 = -432

Answer:

[tex]y-5=\frac{-1}{2}(x+2)[/tex] point-slope form

[tex]y=\frac{-1}{2}x+4[/tex]  slope-intercept form

Step-by-step explanation:

The slope-intercept form of a line is y=mx+b where m is the slope and b is the y-intercept.

The slopes of perpendicular lines are opposite reciprocals.

The slope of y=2x-5 is 2.

So we are looking for a line perpendicular to y=2x-5 which means we first to the take the opposite reciprocal of it's slope giving us:

opposite reciprocal of (2) is opposite (1/2)=-1/2.

So the slope of the line we are looking for is -1/2.

This means are equation for our line is in this form:

[tex]y=\frac{-1}{2}x+b[/tex]

To find b we will use a point (x,y) that is on our line.

We are given a point (x,y)=(-2,5).

Plug this into our equation:

[tex]5=\frac{-1}{2}(-2)+b[/tex]

[tex]5=1+b[/tex]

Subtract 1 on both sides:

[tex]4=b[/tex]

So the equation for our line that we are looking for is:

[tex]y=\frac{-1}{2}x+4[/tex]  (slope-intercept form).

You could also go for point-slope form [tex]y-y_1=m(x-x_1)[/tex] where m is the slope and [tex](x_1,y_1)[/tex] is a point on the line.

We have m=-1/2 and (x1,y1)=(-2,5) so our equation in point slope-form is:

 [tex]y-5=\frac{-1}{2}(x-(-2))[/tex]

Simplifying just a hair:

[tex]y-5=\frac{-1}{2}(x+2)[/tex].

Step-by-step explanation:

There are 30-17 = 13 boys in the class.

a.  Prob(First is a boy ) = 13/30 and Prob( second is a boy = 12/29).

As these 2 events are independent:

Prob( 2 boys being picked) = 13/30 * 12/29 =  26/145 or 0.179 to the nearest thousandth.

b. By a similar method to a:

Prob ( 2 girls being picked) =  17/30 * 16/29 = 136/435 = 0.313 to the nearest thousandth.

c.  Prob (First student is a boy and second is a girl) =  13/30 * 17/29 = 221/870.

Prob ( first student is a girl and second is a boy)  = 17/30 * 13/29 = 221/870

These 2 events are not independent so they are added:

Prob( one of the students is a boy)  = 2 (221/870 =  221/435 = 0.508 to the nearest thousandth.

let's recall Cavalieri's Principle, solids with equal altitudes and cross-sectional areas at each height have the same volume, so even though this cylinder is slanted with a height = x and a radius = 8, the cross-sectional areas from the bottom to top are the same thickness and thus the same area, so its volume will be the same as a cylinder with the same height and radius that is not slanted.

The expression tan(2x)/tan(x) simplifies using the double-angle identity for tangent to 2/(1 - tan^2(x)), which corresponds to Option A.

To simplify the trigonometric expression tan(2x)/tan(x) using double-angle identities, we can use the double-angle identity for tangent:

tan(2x) = 2tan(x)/(1 - tan2(x)).

Now, if we divide tan(2x) by tan(x), we get:

tan(2x)/tan(x) = (2tan(x)/(1 - tan2(x)/tan(x).

With tan(x) in the numerator and denominator, it cancels out, leaving:

2/(1 - tan2(x)).

Therefore, the correct answer is Option A: 2/(1 - tan2(x)).

Answer:

34.24 cm²

Step-by-step explanation:

You first need to find the area of the circle.

4 is radius. r*r*3.14=50.24

Now the triangle is 4*4=16.

50.24-16= 34.24

Answer:

B.

Step-by-step explanation:

The area of the shaded region will be the area of the circle minus the area of the triangle inside the circle. Then:

The circle has radius 4 cm (distance from the center to the edge of the circle), so the area of the circle is

[tex]A=\pi r^2 = 3.14(4cm)^2 = 3.14(16cm^2) = 50.24 cm^2.[/tex]

Now, the area of the triangle is

[tex]A_2 = \frac{b*h}{2}[/tex].

The base of the triangle is the diameter of the circle (as you can see in the image) and the height is the radius of the circle. Then the are of the triangle is

[tex]A_2 = \frac{8*4}{2} = \frac{32}{2} = 16cm^2[/tex].

Finally, the shaded area is [tex]A-A_2 = 50.24-16 = 34.24 cm^2[/tex].

Answer:

Inverse of a function

Step-by-step explanation:

If the x- and y-values in each pair of a set of ordered pairs are interchanged, the resulting set of ordered pairs is known as the inverse of a function.

For example, given the following function:

y = 2x

If x=0 → y= 0

If x=1 → y= 2

If x=2 → y= 4

Now, if we find the inverse of the function:  

y = 2x → x = 2y → y = x/2

Now:

If x=0 → y= 0

If x=2 → y= 1

If x=4 → y= 2

Comparing both cases, you will notice that the ordered pairs are effectively interchanged.

The resulting set of ordered pairs formed by interchanging the x- and y-values in each pair is known as the inverse of the original set.

If the x- and y-values in each pair of a set of ordered pairs are interchanged, the resulting set of ordered pairs is known as the inverse of the original set. In mathematics, an ordered pair is a pair of objects written in a specific order, typically as (x,y). If you switch the positions of the elements to form (y,x), you create an ordered pair that represents the inverse relationship. This is particularly relevant in the context of functions and relations on a Cartesian coordinate system. The concept of ordered pairs is fundamental to understanding mappings and the domain and range of relations.

For example, if you have an ordered pair representing a function, such as (3,4), its inverse would be (4,3). This reflects a new relationship where the original output is now the input and vice versa. The set of all such inverted pairs from a function forms the inverse function, provided that each y value is associated with only one x value (the function is one-to-one).

A relation where the ordering of elements matters contrasts with a set where the order does not affect the identity of the set. Hence, achieving an inverse relationship by switching the ordered pairs is a useful tool in mathematical problem-solving and analysis.

Answer:

-7 + a = 37

Step-by-step explanation:

The value of 'a' is 44 and the equation for the statement "The sum of -7 and a is equal to 37" is -7 + a = 37

Let's start by writing the equation for the given statement:

-7 + a = 37

To find the value of 'a', we need to isolate 'a' on one side of the equation. We can do this by performing inverse operations. The inverse of subtracting 7 is adding 7. So, we will add 7 to both sides of the equation:

-7 + a + 7 = 37 + 7

On the left side, the -7 and +7 cancel out, leaving us with:

a = 44

Therefore, the value of 'a' that satisfies the given equation is 44.
