Seth is using the figure shown below to prove Pythagorean Theorem using triangle similarity:


In the given triangle ABC, angle A is 90° and segment AD is perpendicular to segment BC.


The figure shows triangle ABC with right angle at A and segment AD. Point D is on side BC.


Which of these could be a step to prove that BC2 = AB2 + AC2?

possible answers -
By the cross product property, AB2 = BC multiplied by BD.
By the cross product property, AC2 = BC multiplied by BD.
By the cross product property, AC2 = BC multiplied by AD.
By the cross product property, AB2 = BC multiplied by AD.

Answers

Answer 1

The correct step to prove that [tex]BC^2 = AB^2 + AC^2[/tex] is:

By the cross product property, [tex]AC^2 = BC \cdot AD[/tex].

To prove that [tex]BC^2 = AB^2 + AC^2[/tex], we can use the triangle similarity and the Pythagorean theorem. Here's a step-by-step explanation:

Given triangle ABC with right angle at A and segment AD perpendicular to segment BC.

By triangle similarity, triangle ABD is similar to triangle ABC. This is because angle A is common, and angle BDA is a right angle (as AD is perpendicular to BC).

Using the proportionality of similar triangles, we can write the following ratio:

[tex]$\frac{AB}{BC} = \frac{AD}{AB}$[/tex]

Cross-multiplying, we get:

[tex]$AB^2 = BC \cdot AD$[/tex]

Similarly, using triangle similarity, triangle ACD is also similar to triangle ABC. This gives us:

[tex]$\frac{AC}{BC} = \frac{AD}{AC}$[/tex]

Cross-multiplying, we have:

[tex]$AC^2 = BC \cdot AD$[/tex]

Now, we can substitute the derived expressions into the original equation:

[tex]$BC^2 = AB^2 + AC^2$\\$BC^2 = (BC \cdot AD) + (BC \cdot AD)$\\$BC^2 = 2 \cdot BC \cdot AD$[/tex]

It was made possible by cross-product property.

Therefore, the correct step to prove that [tex]BC^2 = AB^2 + AC^2[/tex] is:

By the cross product property, [tex]AC^2 = BC \cdot AD[/tex].

A car travels 136 miles using 7 gallons of gas. At that rate, how far can the car travel using 42 gallons of gas?

Answers

Answer:

in 136 miles=7 gallons

?=42 gallon

= 136=7

?=42

cross multiply

136×42=5,712

=5,712÷7=816

Answer:

816 miles

Step-by-step explanation:

136miles/7 g =19.43

19.43 x 42 ≅ 816.06

or

136/7 = X/42

solve for X

42/7 =6, then 136 x6= 816

x = 816 miles

A piece of paper has an area of 93.5 square inches. How many times does it need to be folded in half before the area is less than 1 square inch? Explain how you know.

Answers

Answer:

7 times.

Step-by-step explanation:

Keep dividing 93.5 by 2 until it becomes less than 1.

The sheet needs to be folded in half 7 times.

Since the area of the piece of paper is 93.5 square inches, and we need to fold the sheet in half it 'n' times  to get an area less than 1 square inch. This is written mathematically as 93.5(1/2)ⁿ ≤ 1.

So, dividing through by 93.5, we have

(1/2)ⁿ ≤ 1/93.5

(1/2)ⁿ ≤ 0.0107

taking natural logarithm of both sides, we have

㏑(1/2)ⁿ ≤ ㏑0.0107

n㏑(1/2) ≤ ㏑(0.0107)

n ≤ ㏑(0.0107)/㏑(1/2)

n ≤ -4.538/-0.693

n ≤ 6.55

Rounding up to the nearest whole number,

n ≅ 7

So, the sheet needs to be folded in half 7 times.

The principle of superposition is a useful technique in developing solutions to differential equations after an initial solution is derived. In developing such solutions it is often convenient to consider separately the response of a system to initial conditions with all forcing function inputs equal to zero, and, secondly, the response to the forcing function with all initial conditions equal to zero. Consider the following differential equation:

dy/dt + ay= bus(t)

with y(c)=0

a. Determine the solution y_i(t) to the equation for nonzero, finite values of a and c, and for b = 0.

in gallons, how much water is needed in order to make three gallons of cranberry juice? Express your answer as a

common fraction.

Answers

4 1/2 cups of water

Answer:

2 2/5

Step-by-step explanation:

We need to find out how many gallons of water so,

16/20 = water

3 gallons * 16/20 = 48/20 = 2 8/20 = 2 2/5

this works because then cranberries would be:

2 2/5/16 = 15/100

and for sugar that means

15/100 * 3 = 45/100

so in total

2 40/100 + 45/100 + 15/100 = 3 gallons

and if we simpilfy 2 40/200 we get 2 2/5

5. Cuando abrió sus puertas, una tienda de café ofrecía 6 tipos diferentes de
bocadillos. Desde entonces, agregó dos nuevos bocadillos cada semana.
Si la tienda ofrece ahora 28 bocadillos diferentes, ¿cuántas semanas (s) han
transcurrido desde su inauguración?
?

Answers

Answer:

11 weeks have passed.

Step-by-step explanation:

We can create a linear function that represents the number of bocadillos offered as a function of the number of weeks (s) that went by since the beginning (when the number of bocadillos was 6):

f(s) = 6 + 2 * s

Since now the number of bocadillos is 28, we can solve for s in the equation

28 = 6 + 2 * s

subtract 6 from both sides

28 - 6 = 2 * s

22 = 2 * s

divide both sides by 2

11 = s

Therefore, 11 weeks have passed.
