Answer:

  (b)  15 cm, 20 cm, 25 cm

Step-by-step explanation:

Because you know that the triple (3, 4, 5) is a Pythagorean triple, you know that every multiple of it will also give side lengths of a right triangle. Multiplying that triple by 5 gives (15, 20, 25), matching the 2nd choice on the list.

__

Comments on other choices

You also know that (3, 4, 5) is the only Pythagorean triple that has constant differences, so 15, 16, 17 cannot be a right triangle. (It is very nearly an equilateral triangle.)

A right triangle with same-length sides will have a hypotenuse that is √2 times that length, so no right triangle will have two equal integer legs and an integer hypotenuse.

The lengths 15, 18, 33 form a straight line, not even a triangle.

  15^2 +20^2 = 225 +400 = 625 = 25^2 . . . 15, 20, 25 will form a right triangle

Answer:

cccccc

Step-by-step explanation:

Given two functions f and g, we want to see which statement is always true.

The only true statement is the third one:

"If a is in the domain of f + g. then I must be in the domain of f and it must be in the domain of g"

So what we can do, is try to find counterexamples for the given statements, if we can't, then the statements are true.

Note that the statements are really badly written, so I will complete them in a way that makes sense.

a) "If z is in the domain of f. then must be in the domain of f - g"

False, if z is not in the domain of g, then we can't define:

(f - g)(z)

This would happen if:

g = 1/(x - z)

b) "lf 2 is in the domain of f and 22 is in the domain of g, then the product, 222, must be in the domain of fg"

False, lets replace:

2  = z

22 = k

And let's say that:

f(x) = 1/(x - z*k)

g(x) = x

Then we have:

f*g(x) = x/(x - z*k)

Clearly, z*k (or 222 as you wrote it) is not on the domain.

c) "If a is in the domain of f + g. then I must be in the domain of f and it must be in the domain of g"

True, it only can be on the domain of the sum of the two functions if it belongs to the domain of each one.

d) "if a is not in the domain of (f + g) then a is not in the domain of g"

This is false, because a could be in the domain of g and not be in the domain of f.

Then the only true statement is the third one.

Answer:

  y = 1/4x -2

Step-by-step explanation:

The line rises one unit from -2 to -1 as x changes from 0 to 4. The slope is ...

  m = rise/run = 1/4

The y-intercept (b) is where the line crosses the y-axis, at y = -2.

The equation in slope-intercept form is ...

  y = mx + b

  y = 1/4x -2

Answer:

[tex]b=24\ cm[/tex]

Step-by-step explanation:

Right Triangles

In a right triangle, the relationship between the hypotenuse and the two legs is known as the Pythagora's theorem. If c is the hypotenuse and a and b are the legs, then:

[tex]c^2=a^2+b^2[/tex]

Solving for b:

[tex]b=\sqrt{c^2-a^2}[/tex]

We are given the values c=40 cm, a=32 cm. Calculating b:

[tex]b=\sqrt{40^2-32^2}[/tex]

[tex]b=\sqrt{1600-1024}=\sqrt{576}[/tex]

Answer:

She walked neighbor's dog 4 times.

Step-by-step explanation:

It is given that:

Peri earned $27 for walking the dogs 3 times.

Unit rate = [tex]\frac{27}{3}[/tex]

Unit rate = $9 per dog

Now,

Peri worked at the same rate and earned $36.

Unit rate = [tex]\frac{Total\ earning}{Dogs\ walked}[/tex]

[tex]9 = \frac{36}{d}[/tex]

d= 36/9

d = 4

Therefore,

She walked neighbor's dog 4 times.

Answer: Alycia only established some of the necessary conditions for a congruence criterion.

Step-by-step explanation: Two triangles are congruent if their corresponding sides or/and corresponding angles are the same.

There are 5 ways to find out if the triangles are congruent.

The one Alycia used seems to be the one called Side-Angle-Side, which states that if two sides and its included angle is equal to the corresponding sides and angle of the other triangle, they are congruent.

For triangles ΔOPQ and ΔSTR to be congruent, using that theorem:

1) ∠O = ∠S

2) OP = TS

And

3) RS = OQ

So, Alycia's error is that she didn't prove RS = OQ, which would definitively  conclude that both triangles are congruent.

Answer:

Alycia used a criterion that does not guarantee congruence.

Step-by-step explanation:

A proof is a formal description of how we can know that something is true based on the information from a mathematical scenario.

Each step of the proof is a transformation, a construction, or a statement about what we can conclude from earlier steps.

For a two-column proof we give a reason to justify each statement. Common reasons include geometric theorems, algebraic properties, and information given in diagrams.

Let's check the reason for each step and whether Alycia established the conditions for it.

Step 1

The diagram does support the claim that OP=ST=4

Step 1 is correct

Step 2

The diagram does support the claim that OP is parallel to ST because they both have an arrow mark.

Step 2 is correct.

Step 3

<O is indeed congruent to ∠S because they are alternate interior angles between parallel lines.

Step 3 is correct.

Step 4

In this step, Alycia claims that the triangles are congruent using a "side-angle" criterion. She did establish the conditions for claiming that the figures has one pair of congruent corresponding sides and one pair of congruent corresponding angles.

~From Step 1, we know OP is congruent to ST

~From step 2, we know O is congruent to S

(Segments and angles are congruent if and only if they have equal measures.)

However, side-angle congruence is not a valid reason for claiming that two triangles are congruent, so Alycia's reason is inappropriate.

Alycia used a criterion that does not guarantee congruence.

Step-by-step explanation:

Please let me know if you want me to add an explanation as to why this is the answer. I can definitely do that, I just wouldn’t want to write it if you don’t want me to :)

Answer:

The first column is 5 and the second will be 18 and 2 .

Step-by-step explanation:

You only have to substitute the values into the equation :

let x = 9,

y = 2(9)

y = 18

let y = 10,

10 = 2(x)

x = 5

let x = 1,

y = 2(1)

y = 2

Answer:

Kelly is incorrect because she added the two numbers on the number line that made no since.

If Kelly had worked through the problem

P would have equaled 1.2

3.6+(-2.4) = 1.2 which is what p equals

The value of P is 1.2

The value of p is 1.2.

Absolute value of a number is the distance value from zero without considering sign of a number. It is also represented as |x|, where x is any number.

Given that the expression, 3.6 + (-2.4) = p

To find the value of p,

3.6 + (-2.4) = p

p = 1.2

Relation of p in number line with -2.4 and 3.6 ;

p = 1.2 in the number line is right side of -2.4 and left side of 3.6.

Whenever we add the positive numbers we get the sum of the number in the right side of both the positive number.

And whenever we add the negative numbers we get the sum of the number in left side of both of the negative number.

And when we add the positive and negative number then if

1) positive number > absolute value of negative number then sum of the numbers will be in the middle of the both number.

And 2) if positive number < absolute value of negative number then the sum of the numbers will be in the middle of both of the number.

Therefore the value of p is 1.2.
