The function g(x) represents f(x) = 9 cosine (x minus StartFraction pi Over 2 EndFraction) + 3 after translating StartFraction pi Over 6 EndFraction units left and 4 units up.Which equation represents g(x)?

Answers

The equation that represents the function g(x) is $g(x)=9cos(x-(\pi )/(3) )+7$ .

What is function?

Function, in mathematics, an expression, rule, or law that defines a relationship between one variable (the independent variable) and another variable (the dependent variable).

What is translation?

Translation means the displacement of a figure or a shape from one place to another. In translation, a figure can move upward, downward, right, left or anywhere in the coordinate system. In translation, only the position of the object changes, its size remains the same.

The function is given as

$f(x)=9cos(x-(\pi )/(2) )+3$

The function f(x) is first translated $(\pi )/(6)$ units left.

The rule of translation is:

$(x,y)=(x+(\pi )/(6),y)$

So, we have:

$f'(x)=9cos(x+(\pi )/(6) -(\pi )/(2) )+3$

Take LCM

$f'(x)=9cos(x+(\pi-3\pi )/(6) )+3$

$f'(x)=9cos(x-(2\pi )/(6) )+3$

$f'(x)=9cos(x-(\pi )/(3) )+3$

Next, translate f'(x) 4 units up.

The rule of this translation is:

$(x,y)=(x,y+4)$

So, we have:

$g(x)=9cos(x-(\pi )/(3) )+3+4$

$g(x)=9cos(x-(\pi )/(3) )+7$

Hence, the equation that represents the function g(x) is $g(x)=9cos(x-(\pi )/(3) )+7$ .

Change 11 5/8 to a improper fraction

Answers

Simple,

You have 11 $(5)/(8)$

to change it into an improper fraction multiply the whole number (11) by the denominator (8)

11*8=88

Then, add the numerator to what you have multiplied..

88+5=93

Finally, use the original denominator....

Making your answer...

$(93)/(8)$

Thus, your answer.

Final answer:

To convert 11 5/8 to an improper fraction, multiply the whole number by the denominator and add the numerator. The result is 93/8.

Explanation:

The process to change 11 5/8 to an improper fraction involves two main steps. Firstly, you multiply the whole number (11 in this case) by the denominator of the fraction (8). The result is 88. Secondly, add the numerator of the fraction (5) to this result. Therefore, 88 + 5 = 93. Hence, the improper fraction form of 11 5/8 is 93/8. It is called an improper fraction because the numerator is greater than the denominator.

What is the diagonal of a rectangle with length 48 inches and width 40 inches?

Answers

Use the Pythagorean Theorem: $a^2 + b^2 = c^2$
You can do this because when you cut the rectangle in half with the diagonal, it forms a right triangle, making the diagonal the hypotenuse (c).

$40^2 + 48^2 = c^2$

$1600 + 2304 = c^2$

$3904 = c^2$

$√(3904) = √(c^2)$

$62.48 = c$

Diagonal: 62.48 inches

i think its D=w2+l2=402+482≈ 62.482in
