3. 6/8/10 is twice the common Pythagorean Triple 3/4/5.

Answer: A. 10

4. 3/4/5 is a Pythagorean Triple because they're three natural numbers that satisfy a²+b²=c^2, here 3²+4²=5².

Answer: C

Non-zero whole numbers are called natural numbers.

Answer:

3 10

4 C yes it is a pythagorean triple 3^2 +4^2 = 5^2

Step-by-step explanation:

We can find the unknown side by using the Pythagorean theorem

a^2 +b^2 = c^2

6^2 +8^2 = c^2

36+64 =c^2

100 = c^2

Take the square root of each side

sqrt(100) = sqrt(c^2)

10 = c

4. a^2 +b^2 = c^2

3^2 +4^2 = 5^2

9+16= 5^2

25 = 25

Since the numbers fit the Pythagorean theorem, it is a Pythagorean triple

19-24-30,

7-24-25

Step-by-step explanation:

In a triangle with side lengths $a$ , $b$ , and $c$ , any two sides must have a sum larger than the third.

Using this rule, the possible side lengths out of these choices that could form a triangle are:

In the figure, triangle CAE is an enlargement of triangle CBD with scale factor of 4/3. The area of the smaller triangle is 9cm2

balandron [24]

Answer:

16 cm^2

Step-by-step explanation:

Given

$\triangle CAE$ -- Bigger Triangle

$\triangle CBD$ -- Smaller Triangle

$k = \frac{4}{3}$ --- Scale factor

Area of CBD = 9

Required

Determine the area of CAE

The area of triangle CBD is:

$A_1 = \frac{1}{2}bh$

$\frac{1}{2}bh = 9$

The area of CAE is:

$A_2 = \frac{1}{2}BH$

Where:

$B = \frac{4}{3}b$ and

$H = \frac{4}{3}h$

The above values is the dimension of the larger triangle (after dilation).

So, we have:

$A_2 = \frac{1}{2}*\frac{4}{3}b * \frac{4}{3} * h$

$A_2 = \frac{1}{2}*\frac{4}{3} * \frac{4}{3} *b* h$

$A_2 = \frac{1}{2}*\frac{16}{9} *b* h$

Re-order

$A_2 = \frac{16}{9}*\frac{1}{2}* b* h$

$A_2 = \frac{16}{9}*\frac{1}{2}bh$

Recall that:

$\frac{1}{2}bh = 9$

$A_2 = \frac{16}{9}*9$

$A_2 = 16$

Hence, the area is 16 cm^2

Which best describes the transformation that occurs from the graph of f(x) = x2 to g(x) = (x – 2)2 + 3?

Stels [109]

Right 2 up 3 because when the change happens within x the opposite result happens but for vertical it remains the same . So the answer is right 2, up 3

Polyhedron P is a cube with a corner removed and relocated to the top of P. Polyhedron Q is a cube. How do their surface areas c

tatiyna

Answer:

C. P’s surface area is greater than Q’s surface area.

Step-by-step explanation:

Refer to attached

With a corner removed, it doesn't change surface area of the cube as same area is exposed equal to the area of 3 small faces.

With the corner relocated to the top of the cube, it covers the area of one small face but adds up small 5 faces (4 sides and one top). In total the P has more surface area than the Q.

Correct answer choice is C.
