Answer:

q=1

Step-by-step explanation:

(I will use the cross multiplication method)

Step 1: multiply 20 x 4 (80)

Step 2: divide 80 by 40 (2)

Step 3: subtract 1 from the 2

4/1 = 40/20

If you want to check multiply 40 x 2 and 20 x 4

if they have the same answer then your answer is right.

40 x 2= 80

20 x 4=80

80=80

Answer:

q=1

Step-by-step explanation:

$\frac{4}{q+1} =\frac{40}{20} \\\\\frac{4}{q+1} =\frac{4}{2} \\\\\frac{4}{q+1} =\frac{4}{2} \\\\\frac{4}{q+1} =\frac{2}{1} \\\\\frac{2}{q+1} =\frac{1}{1} \\\\q+1=2\\q=1$

What is the transformation of f(x)= x^3:

mariarad [96]

Answer:

7. Down 5

8. Horizontal reflection

9. Vertical stretch by a factor of 5

Step-by-step explanation:

Transformations of Graphs (functions) is the process by which a function is moved or resized to produce a variation of the original (parent) function.

Transformations

For a > 0

$f(x+a) \implies f(x) \: \textsf{translated}\:a\:\textsf{units left}$

$f(x-a) \implies f(x) \: \textsf{translated}\:a\:\textsf{units right}$

$f(x)+a \implies f(x) \: \textsf{translated}\:a\:\textsf{units up}$

$f(x)-a \implies f(x) \: \textsf{translated}\:a\:\textsf{units down}$

$y=a\:f(x) \implies f(x) \: \textsf{stretched parallel to the y-axis (vertically) by a factor of}\:a$

$y=f(ax) \implies f(x) \: \textsf{stretched parallel to the x-axis (horizontally) by a factor of} \: \dfrac{1}{a}$

$y=-f(x) \implies f(x) \: \textsf{reflected in the} \: x \textsf{-axis}$

$y=f(-x) \implies f(x) \: \textsf{reflected in the} \: y \textsf{-axis}$

Identify the transformations that take the parent function to the given function.

Question 7

$\textsf{Parent function}: \quad f(x)=x^3$

$\textsf{Given function}: \quad f(x)=x^3-5$

Comparing the parent function with the given function, we can see that 5 has been subtracted from the parent function.

Therefore, the transformation is:

$f(x)-5 \implies f(x) \: \textsf{translated}\:5\:\textsf{units down}$

Question 8

$\textsf{Parent function}: \quad f(x)=x^3$

$\textsf{Given function}: \quad f(x)=-x^3$

Comparing the parent function with the given function, we can see that the parent function has been multiplied by -1.

Therefore, the transformation is:

$y=-f(x) \implies f(x) \: \textsf{reflected in the} \: x \textsf{-axis}$

Question 9

$\textsf{Parent function}: \quad f(x)=x^3$

$\textsf{Given function}: \quad f(x)=5x^3$

Comparing the parent function with the given function, we can see that the parent function has been multiplied by 5.

Therefore, the transformation is:

$y=5\:f(x) \implies f(x) \: \textsf{stretched parallel to the y-axis (vertically) by a factor of}\:5$

Leon verified that the side lengths 21, 28, 35 form a Pythagorean triple using this procedure. Step 1: Find the greatest common

PSYCHO15rus [73]

Answer:

Yes, multiplying every length of a Pythagorean triple by the same whole number results in a Pythagorean triple.

Step-by-step explanation:

The missing options are:

Yes, multiplying every length of a Pythagorean triple by the same whole number results in a Pythagorean triple.

Yes, any set of lengths with a common factor is a Pythagorean triple.

No, the lengths of Pythagorean triples cannot have any common factors.

No, the given side lengths can form a Pythagorean triple even if the lengths found in step 2 do not.

A Pythagorean triple is a group of three integers (a, b and c) that satisfies the next equation:

c² = a² + b²

Multiplying the three integers by the same positive integer, you would get another Pythagorean triple.

(kc)² = (ka)² + (kb)²

k²c² = k²a² + k²b²

k²c² = k²(a² + b²)

c² = a² + b²

The procedure followed by Leon is the opposite. He found the greatest common factor and divided the given lengths by the greatest common factor, obtaining the simplest Pythagorean triple, which is (3,4,5)
