State if each triangle is a right triangle: *

13 in
2 in
12 in

Answers

Answer:

It would be a obtuse triangle instead

Step-by-step explanation:

By using pythagorean and theorem (a^2 + b^2 = c^2)

So it would be 13^2___2^2 + 12^2

When you square them, you get 169___4 + 144

144 + 4 = 148, which is less than 169

SO it would be 169>148

So no, not a right triangle

Answers

Hope that helped! The answer is t is less than or equal to 6

The value of t will be  t ≥ 6 or t ∈ [ 6 , α ) .

Given,

-2t + 5 ≥ -7

Now,

Solving the inequality,

-2t + 5 ≥ -7

Take 5 from LHS of inequality to RHS of inequality .

-2t ≥ -12

The negative signs from both sides are eliminated .

2t ≥ 12

t≥ 12/2

t≥ 6 .

Thus the value of inequality will be t ≥ 6 .

Part 1: Simplify √250


Part 2: Classify the number above as rational or irrational


Level 3 (Proficient: 85%)


Part 1: Simplify √150x*5


Part 2: Is the follow expression rational or irrational and why? 2√4+7


Level 4 (Distinguished: 100%)


Part 1: Simplify 13√750x*5 y*8


Part 2: Create two unique expressions each involving 1 square root and at least 1 operation (adding, subtracting, multiplying, dividing). Make 1 results in a rational number and the other result in an irrational number. Explain your reasoning for both.

Answers

Explanation:

Level 2

Part 1: √250 would be simplified to 5√10, because you need to find two factors that equal 250. 25 multiplied by 10 are two factors that you can utilize. Because 25 is a perfect square, it could be reduced to 5. Because 10 isn't a perfect square, you leave it as a radical.

Part 2: √250 is an irrational number because it's a non-terminating decimal and you cannot convert it into a fraction, so it wouldn't be rational.

Level 3

Part 1: √150x^5 would be simplified to 5x^2√6x. Again, find two factors that equal the product, 150. 25 multiplied by 6 are two factors that are useable. Just like the first question, 25 is a perfect square, so it can be reduced to 5. 6 is not a perfect square, so you would leave as a radical. Now, moving onto x^5. You can factor out x^4, because it's a perfect square. x^4 can become x^2. Move x^2 next to 5 and x would be left in the radical with 6.

Part 2: It's rational because 2√4 is simply just 2 x 2 because √4 is a perfect square. 4+7=11. 11 can be converted into a fraction, so it wouldn't be irrational.

Level 4

Part 1: 13√750x*5 y*8 would be simplified to 65x^2y^4√30x. Find two factors that equal 750, which are 25 and 30. You know the drill, 25 is reduced to 5 and 30 stays as a radical. Multiply 13 and 5 to get 65. Factor out x^4 out of x^5 to get x^2. x^8 is a perfect square that can be reduced to x^4.

Part 2: Two unique expressions are 4√16+3 and 5√8 x 34. √16 is a perfect square, so it can become 4. 4 x 4 is 16 and 16 + 3 = 19. 19 is a rational number. 5√8 is irrational, so right off the bat, you'll know it's an irrational expression.

A plumber charges a one-time service fee of $20 in addition to his hourly rate of $25 per hour. If the plumber went to your house to work on your bathtub and toilet and the bill came to $282.50, how many hours did it take him to complete the job?

A- 25 + 20x = 282.50; x = 10.5 hours

B- 20 + 25x = 282.50; x = 10.5 hours

C- 20 + 25x = 282.50; x = 12.1 hours

D- 45x = 282.50; x = 6.3 hours

Answers

Answer: B

Step-by-step explanation:

The number of hours it took him to complete the job is; Choice B: 20 + 25x = 282.50; x = 10.5 hours

According to the question;

The one-time service fee of the plumber is; $20

The plumber's hourly rate is; $25 per hour.

The total bill after working on toilet and bathroom came to; $282.50

The expression which represents the plumber's charge is therefore;

20 + 25x = 282.50

where, x = number of hours to complete the job.

Therefore, to find x;

25x = 282.50 - 20

25x = 262.50

x = 262.50/25

x = 10.5 hours.

The total number of hours it took him to complete the job is; 10.5 hours.

Simplify (4i) (5i) - The “i” is the imaginary number for negative 1

Answers

Answer:

-20

Step-by-step explanation:

The simplified form of the given complex number (4i)(5i) is -20.

To simplify the expression (4i)(5i), we can use the properties of complex numbers.

The imaginary unit i is defined as the square root of -1. So, i² = -1.

Now let's simplify the given expression:

(4i)(5i) = 20i²the simplified form of (4i)(5i) is -20.

Since i² equals -1, we can substitute -1 for i²:

20i² = 20(-1)

Multiplying -1 by 20, we get:

20(-1) = -20

Therefore, the simplified form of (4i)(5i) is -20.

Over which interval of the domain is function m negative?

Answers

Answer:

The interval of the domain over which the function m is negative

Step-by-step explanation:

We have to determine the interval of the domain over which the function m is negative.

The x-intercept of the graph is:

at y = 0, x = 6

(0, 6) is the x-intercept.

From the graph, it is clear that at the x-intercept x=6, the graph tends to continue downward towards infinity i.e. (6, ∞) where the graph would be negative as it is heading downwards.

Thus, the interval of the domain over which the function m is negative will be: (6, ∞)
