Right Triangles

Right triangles have one of its interior angles with a measure of 90°.

In right triangles the Pythagora's Theorem is satisfied.

Being c the longest side (hypotenuse), a and b the shorter sides (the legs), then:

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

We have modified the image to include some known data. Both triangles are congruent since they share one side, have a right angle, and have the same base length.

This means the value of x can be calculated as the hypotenuse of the triangle 3-6-x:

[tex]x^2=3^2+6^2=9+36=45[/tex]

[tex]x=\sqrt{45}=\sqrt{9*5}[/tex]

If f(x) = x2 + 2x + 1 and g(x) = 3(x + 1)2, which is an
equivalent form of f(x) + g(x)?
O x2 + 4x + 2
O 4x2 + 2x + 4
O 4x2 + 8x + 4
o 10x2 + 20x + 1

Answers

the answer should be C

The equivalent form of f(x) + g(x), if  f(x) = x² + 2x + 1 and g(x) = 3(x + 1)² is

4x² + 8x + 4, so option C is correct.

What is a function?

In the case of a function from one set to the other, each element of X receives exactly one element of Y. The function's domain and co-domain are respectively referred to as the sets X and Y as a whole.

Given:

f(x) = x² + 2x + 1 and g(x) = 3(x + 1)²

Calculate the equivalent form as shown below,

f(x) + g(x) = x² + 2x + 1 + 3(x + 1)²

Simplify the above equation,

f(x) + g(x) = x² + 2x + 1 + 3(x² + 2x + 1)

f(x) + g(x) = x² + 2x + 1 + 3x² + 6x + 3

f(x) + g(x) = 4x² + 8x + 4

Find the cost of 80 Orange at 5 for 30 naria

Answers

By selling 80 oranges a man gains a cost price of 20 oranges. What is the gain percentage?
To solve this tricky question, let the cost price (CP) of an orange is 1 Rs.

Now CP of 80 oranges = 80 Rs………..(1)

And we know that

Profit= SP (selling price) - CP (cost price)

Here;

Profit = SP of 80 oranges - CP of 80 oranges…….(2)

{Here profit is already given that is CP of 20 oranges }

By (2);

CP of 20 oranges = SP of 80 oranges - CP of 80 oranges

Or

CP of 100 oranges = SP of 80 oranges

Or

SP of 80 oranges = 100 Rs…………(3)

{ cp of 1 orange is 1 Rs.}

Here we have

CP = 80 rs.

SP = 100 rs.

% profit = (SP - CP)*100/CP

% profit = (100–80)*100/80 = 20*100/80 = 25%

So %profit is 25%

At Emmy's Swimwear, there are 28 bikini styles and 42 other types of swimsuit. What percentage of the swimsuit styles are bikinis?

Answers

Answer:

Approximately 66.66% of swimsuit styles are bikinis.

Step-by-step explanation:

Given

Bikini styles Swimwear = 28Other types of Swimsuit = 42

Let 'x' be the percentage of the swimsuit styles are bikinis.

so

x% of 42 = 28

[tex]\frac{x}{100}\times \:42=28[/tex]

[tex]42x = 100 \times 28[/tex]

[tex]42x = 2800[/tex]

divide both sides by 42

[tex]\frac{42x}{42}=\frac{2800}{42}[/tex]

simplify

[tex]\:\:x\:\approx \:66.66\:\%[/tex]

Therefore, Approximately 66.66% of swimsuit styles are bikinis.
