Answer:

5. the given ordered pair is not a solution 6. the given ordered pair is a solution 7. the given ordered pair is a solution

Step-by-step explanation:

5. 8 = -4(-2) => 8 = 8 (true)

8 = 1/2(-2) + 7 => 8 ≠ 6 (false)

the given ordered pair is not a solution

6. 3 + 5(1) = 8 => 8 = 8 (true)

4(3) - 5(1) = 7 => 7 = 7 (true)

the given ordered pair is a solution

7. -5 = 4 - 9 => -5 = -5 (true)

4 + (-5) = -1 => -1 = -1 (true)

the given ordered pair is a solution

Prove algebraically that the square of any number is always 1 more than a multiple of 8

Answers

Answer:

This is interesting but I don't think it's provable (unless it's just the square of odd numbers).

3² = 9, which is 1 more than a multiple of 8  (8)

4² = 16, which is not 1 more than a multiple of 8  (8)

5² = 25, which is 1 more than a multiple of 8  (24)

6² = 36, which is not 1 more than a multiple of 8  (32)

7² = 49, which is 1 more than a multiple of 8  (48)

8² = 64, which is not 1 more than a multiple of 8  (64)

9² = 81, which is 1 more than a multiple of 8  (80)

Which systems are also guaranteed to have a solution of (9,-5)? Select all that apply.

.......

Answers

A is gonna be the right one

Any system of equations that can be written in this form with real coefficients A, B, C, D, E, and F will have a solution of (9,-5).

What is a system of equation?

If the system of equations has a solution of (9,-5), then we can substitute x = 9 and y = -5 into the equations and verify that they are true:

A(9) + B(-5) = C

D(9) + E(-5) = F

Simplifying these equations, we get:

9A - 5B = C

9D - 5E = F

So, any system of equations that can be written in this form will also have a solution of (9,-5):

9A - 5B = C

9D - 5E = F

Therefore, any system of equations that can be written in this form with real coefficients A, B, C, D, E, and F will have a solution of (9,-5).

The right rectangular prisms are similar. The bigger prism has a length of 2.2, width of .8, and height of 3.2. The smaller prism has a length of 1.1, width of .4, and height of 1.6.


Which statements are correct? Check all that apply.


- The angles in the smaller prism measure 90 degrees.


- The perimeter of the rectangular bases changes by a factor of 2.


- The surface area changes by a factor of 8.


- The larger prism has twice the volume of the smaller prism.


- The area of the rectangular bases changes by a factor of 4.

Answers

Answer:

The angles in the smaller prism measure 90 degrees.

The perimeter of the rectangular bases changes by a factor of 2.

The area of the rectangular bases changes by a factor of 4.

Step-by-step explanation:

Two polygons are said to be similar if they have the same shape and angles. Also, the ratio of their corresponding sides are to be in the same proportion.

A) Since the two prism are similar, therefore they are to have the same angle measure. The bigger prism has angles with measure of 90°, hence the angles in the smaller prism will also measure 90.

 

B) Perimeter of bigger prism base = 2(2.2 + 0.8) = 6

Perimeter of smaller prism base = 2(1.1 + 0.4) = 3

Hence, The perimeter of the rectangular bases changes by a factor of 2 (6 / 3).

 

C) Surface area of bigger prism = 2(2.2*0.8 + 3.2*0.8 + 3.2*2.2) = 22.72

Surface area of smaller prism = 2(1.1*0.4 + 1.6*0.4 + 1.6*1.1) = 5.68

22.72 / 5.68 ≠ 8, hence the surface area does not change by a factor of 8

Option C is wrong

D) Volume of bigger prism = 3.2 * 2.2 * 0.8 = 5.632

Volume of smaller prism = 0.4 * 1.6 * 1.1 = 0.704

The volume of larger prism is not twice of the smaller prism (5.732 / 0.704 ≠ 2)

 

E) Area of bigger prism base = 2.2*0.8 = 1.76

Area of smaller prism base = 2.2*0.8 = 0.44

Since 1.76 / 0.44 = 4; The area of the rectangular bases changes by a factor of 4

If cosec theta-cot theta is equal to 1/M then what is the value of cosec theta +cot theta ​

Answers

Given:

[tex]\text{cosec}\theta -\cot \theta =\dfrac{1}{M}[/tex]

To find:

The value of [tex]\text{cosec}\theta +\cot \theta [/tex].

Solution:

We have,

[tex]\text{cosec}\theta -\cot \theta =\dfrac{1}{M}[/tex]

We know that,

[tex]\text{cosec}^2\theta -\cot^2 \theta=1[/tex]

It can be written as:

[tex](\text{cosec}\theta -\cot \theta)(\text{cosec}\theta +\cot \theta)=1[/tex]

[tex]\dfrac{1}{M}\times (\text{cosec}\theta +\cot \theta)=1[/tex]

[tex]\text{cosec}\theta +\cot \theta=1\times M[/tex]

[tex]\text{cosec}\theta +\cot \theta=M[/tex]

Therefore, the value of [tex]\text{cosec}\theta +\cot \theta [/tex] is [tex]M[/tex].

James is reading a book and noticed the page numbers are consecutive integers whose product is 1640. What is the value of the larger page number?

Answers

Answer:

41

Step-by-step explanation:

A pair of consecutive numbers is written as: N and N + 1

(where the larger page number is N + 1)

And we know that the product of these numbers is 1640.

Then:

(N)*(N + 1) = 1640

Solving for N, we get:

N^2 + N = 1640

N^2 + N - 1640 = 0

This is a quadratic equation, remember that for a general quadratic equation:

a*x^2 + b*x + c = 0

The solutions are:

[tex]x = \frac{-b\pm \sqrt{b^2 - 4*a*c} }{2*a}[/tex]

In our case, the solutions are:

[tex]N = \frac{-1 \pm \sqrt{(1)^2 - 4*1*(-1640)} }{2} = \frac{1 \pm 81}{2}[/tex]

Then the two solutions are:

N = (-1 + 81)/2 = 40

N = (-1 - 81)/2 = -41

Because N represents the number on a page, it only can be a positive value, then we take the positive solution.

Then the two consecutive numbers, N and N + 1

are:

N = 40

N + 1 = 41

The value of the larger page number is 41.

Many credit card companies charge a compound interest rate of 1.8% per month on a credit card balance. Nelson owes $950

Answers

Answer:

950, 1121.00, 1322.78, 1,560.88, 1,841.84

Step-by-step explanation:

Calculation to determine the sequences that describes his increasing monthly balance

Based on the information given in order for us to determine the sequence we have to multiply the amount owes by the interest rate and then add back the answer you got to the previous amount you multiplied the interest rate to.

First sequence will be the amount he owes on a credit which is $950

Second sequence

950 * .018 = 171.00

950 + 171.00 = 1121.00

Third sequence

1121.00 * .018 = 201.78

1121.00 + 201.78 = 1322.78

Fourth sequence

1322.78*0.18=238.10

1322.78+238.10=1,560.88

Last sequence

1,560.88*0.18=280.96

1,560.88+280.96=1,841.84

Therefore the sequences that describes his increasing monthly balance are:

950, 1121.00, 1322.78, 1,560.88, 1,841.84
