Se ha construido un cuadrado sobre cada lado del triángulo rectángulo, Pitágoras dice que el cuadrado de área 25 cm2, es igual a sumar las áreas de los otros dos cuadrados, es decir, 16 cm2 y 9 cm2. Escribir la expresión algebraica que mejor represente la relación entre las áreas en la figura.

Answer:

4

Step-by-step explanation:

Answer:

63 degrees

Step-by-step explanation:

Since this is an isosceles triangle, the two bottom angles must be equal, while the top angle (in the way this specific triangle is oriented) must be different. Therefore, angle CDB is 63 degrees.

Answer:

∠CDB = 63°

Step-by-step explanation:

∠CBD and ∠CDB opposite side lengths are congruent (indicated by the little markings)

Because their opposite sides are congruent they are too congruent

So ∠CBD = ∠CDB

because ∠CBD = 63° ∠CDB also equal 63°

Answer:

The expression that represents the approximate area of the circle in square inches is;

9.42 times 3

Step-by-step explanation:

From the question, we have;

The shape of the figure which Kyra is finding the area for = A circle;

The number of equal pieces Kyra cuts the shape into = 8 equal sectors

The shape the sectors are arranged into = A parallelogram

The base of the parallelogram = 9.42 inches

The height of the parallelogram = 3 inches

Therefore, the area of the approximate parallelogram formed ≈  The area of the circle

The area of a parallelogram = The base × The height

∴ The area of the approximate parallelogram formed = 9.42 × 3 ≈ The area of the circle

The approximate area of the circle = 9.42 × 3 square inches.

Answer:

B

Step-by-step explanation:

Just to simplify the top answer :)

Answer:

Angle 1: 40

Angle 2: 40

Step-by-step explanation:

A triangle's angles will ALWAYS add up to 180 degrees total, therefore you can subtract 100 from 180 to find what the measure of A and B are combined.

180 - 100 = 80

So now we know Angles A and B add to 80 degrees, but individually, each is half of that, so both are 40 degrees.

Answer:

[tex]y=2(x+6)^2+7[/tex]

[tex](-6,7)[/tex]

Step-by-step explanation:

[tex]y=2x^2+24x+79[/tex]

Completing the square is a process of converting a quadratic equation in standard form into vertex form.

The first step in completing the square is grouping the quadratic and linear terms of the quadratic equation.

[tex]y=(2x^2+24x)+79[/tex]

Factor out the coefficient of the quadratic term,

[tex]y=2(x^2+12x)+79[/tex]

Now complete the square, add a term to make the grouped part of the equation a complete square, then balance the equation.

[tex]y=2(x^2+12x+36-36)+79[/tex]

Simplify,

[tex]y=2(x^2+12x+36)+79+(2)(-36)[/tex]

[tex]y=2(x+6)^2+79-72[/tex]

[tex]y=2(x+6)^2+7[/tex]

The x-coordinate of the vertex of the equation is equal to (-1) times the numerical part of the quadratic term, and the y-coordinate is equal to the constant.

[tex](-6,7)[/tex]

Answer:

y = -3/11x + 4/11

Step-by-step explanation:

y2 - y1/ x2 - x1

-1 - 2/ 5 - (-6)

-3 / 11

y = -3/11x + b

-1 = -3/11(5) + b

-1 = -15/11 + b

4/11 = b

Answer:

[tex]B = 50.5^\circ[/tex]

Step-by-step explanation:

Given

[tex]AB = 11[/tex]

[tex]BC = 7[/tex]

See attachment

Required

Determine [tex]\angle ABC[/tex]

[tex]\angle ABC[/tex] implies that we calculate the angle at B.

Given that:

[tex]AB = 11[/tex] --- Hypotenuse

[tex]BC = 7[/tex] --- Adjacent of B

We apply cosine formula

[tex]\cos(B) = \frac{Adjacent}{Hypotenuse}[/tex]

[tex]\cos(B) = \frac{BC}{AB}[/tex]

[tex]\cos(B) = \frac{7}{11}[/tex]

[tex]\cos(B) = 0.6364[/tex]

Take arccos of both sides

[tex]B = cos^{-1}(0.6364)[/tex]

[tex]B = 50.5^\circ[/tex]

Answer:

9.

Step-by-step explanation:

It's further away from the other numbers by a significant amount.

Answer:

B. x=6

move all terms to the left that don't contain x to the right side and solve.

It might be 0.432 because add all the mornings numbers, 19,2,6,16.

19+2+6+16 = 43.

How many Freshman? 19 so 19/43 and then you divide 19 and 43

19/43 and you get 0.4418604651 about and it looks to be close to 0.432.

Answer: x > -8

Step-by-step explanation: the line is going to 8 then 9, 10, etc. so greater than ; the circle on #8 isn't filled in so there won't be a line by the sign

Answer:

[tex]x=21.6[/tex]

Step-by-step explanation:

Use the Pythagorean theorem to solve this problem. The Pythagorean theorem states the following,

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

Where (a) and (b) are the legs or the sides adjacent to the right angle, and (c) is the hypotenuse or the side opposite the right angle.

Use the Pythagorean theorem in the right triangle with legs (15) and (18),

[tex](15)^2+(18)^2=c^2\\\\225 + 324=c^2\\\\549=c^2\\\\\sqrt{549}=c[/tex]

Use the Pythagorean theorem again in the right triangle with the legs (18) and (x)

[tex](x)^2+(18)^2=c^2\\\\\sqrt{x^2+324}=c[/tex]

Use the Pythagorean theorem one final time in the larger triangle,

[tex](\sqrt{x^2+324})^2+(\sqrt{549})^2=(x+15)^2\\[/tex]

Simplify, remember that anything to the power (2) is equal to the base (number under the exponent) times itself,

[tex]x^2+324+549=x^2+30x+225[/tex]

[tex]x^2+873=x^2+30x+225[/tex]

Inverse operations,

[tex]x^2+873=x^2+30x+225\\-x^2\\\\873=30x+225\\-225\\\\648=30x\\/30\\\\\frac{648}{30}=x\\\\21.6=x[/tex]

Answer:

mode = 2

Step-by-step explanation:

mode is the most frequently seen number.

median is the average so 5+4+2+2+2+2+1+1+3+2+2+3+3+2+1/15= 2 1/3

Answer:

Median is 2, Mode is 2

Step-by-step explanation:

1,1,1,2,2,2,2,2,2,2,3,3,3,4,5 to get the median you put the number from smallest to large then you x one out on each side until there is only one number left which would be 2

The mode is 2 because it is the most common number (aka it appears the most in the list)
