Answer:

$\boxed{a = 16}$

Step-by-step explanation:

$if \: the \: question \: is \to \: 6= \frac{a}{4} +2 \\ 6(4) = \frac{a}{4} (4) + 2(4) \\ 24 = a + 8 \\ 24 - 8 = a \\ \boxed{a = 16}$

Which best describes the transformation that occurs from

Virty [35]

Answer:

left 3, up 4

Step-by-step explanation:

If the function $y=f(x)$ s translated

$a$ units to the right, then its equation is $y=f(x-a);$
$a$ units to the left, then its equation is $y=f(x+a);$
$a$ units up, then its equation is $y=f(x)+a;$
$a$ units down, then its equation is $y=f(x)-a.$

In your case, the function $g(x)=(x+3)^2+4$ can be obtained from the function $f(x)=x^2$ by translation 3 units to the left and 4 units up.

If F (7) 22, Then F(f-1(22))

jeka57 [31]

Answer:

$\boxed{\boxed{f(f^{-1}(22))=22}}$

Step-by-step explanation:

$\text{If we have}\ f(x)\ \text{and}\ f^{-1}(x),\ \text{then}\\\\\text{if}\ f(a)=b,\ \text{then}\ f^{-1}(b)=a.\\\\\text{Therefore, if}\ f(7)=22,\ \text{then}\ f^{-1}(22)=7.\\\\f(\underbrace{f^{-1}(22)}_{=7})=f(7)=22$

<h2>○=> <u>Correct option</u> :</h2><h2> $\color{plum}\tt\bold{(B)}$ </h2><h3>○=> <u>Steps to derive correct option</u> :</h3>

We know that :

$\color{hotpink} \tt \: circumference \: of \: a \: circle\color{plum} = 2\pi r$

So, let the diameter of this circle be x.

Which means :

$=\tt2 \times \pi \times r$

$=\tt 2 \times x \times \pi = 12\pi$

$=\tt 2x\pi = 12\pi$

$=\tt x = \frac{12}{2}$

$= \tt \: x = 6 \: m$

Thus, the radius of the circle Robert drew = 6 m

Since the circle in option B has a radius of 6 m, it is the circle Robert drew.

▪︎<em>Therefore, the correct option is (B)</em>
