You can simplify the given expression by taking out those factors who are perfect squares.

The simplified form  of the given expression will be  \dfrac{\sqrt{3}}{2}

<h3>How to simplify values which are under the root?</h3>

If possible, try to defactor what is inside the root.

For example, if 8 is under square root, then you can defactor 8 as made up of 2 times 2 times 2. Since 2 times 2 is perfect square, thus this can come out of the root.

Simply, some more such methods can be used to simplify these type of values.

<h3>Using the simplification method on given expression</h3>

\dfrac{3\sqrt{8}}{4\sqrt{6}} = \dfrac{3\sqrt{2 \times 2 \times 2}}{4\sqrt{6}}\\\\&#10;\dfrac{3\sqrt{8}}{4\sqrt{6}} = \dfrac{3 \times 2\sqrt{2}}{4\sqrt{6}}\\&#10;&#10;\\&#10;\dfrac{3\sqrt{8}}{4\sqrt{6}}  = \dfrac{6\sqrt{2}}{4\sqrt{6}} = \dfrac{\sqrt{6}\sqrt{2}}{4}\\\\&#10;\dfrac{3\sqrt{8}}{4\sqrt{6}}  = \dfrac{\sqrt{12}}{4} = \dfrac{\sqrt{4 \times 3}}{4} = \dfrac{\sqrt{3}}{2}

Thus, after getting simplified, the expression becomes \dfrac{\sqrt{3}}{2}

If f(x) = 3x^2+ 3x^(1/2) + 3x, then f(-9) is equal to
ivanzaharov [21]

Since

f(x)=3x^2+3\sqrt{x}+3x

the domain of f(x) is the set of non-negative integers, because we can't feed a square root with negative inputs. So, you couldn't comput f(-9)

Unless you're allowed to use complex numbers, in that case we have

f(-9)=3\cdot (-9)^2+3\sqrt{-9}+3\cdot (-9)=3\cdot 81+3\cdot (9i)-27

Which evaluates to

243+27i-27=216+9i

RideAnS [48]

Answer:

Step-by-step explanation:

1). y = - 4x + 7

Reflected across what????

if x-axis, then y ⇒ - y

So the answer would be <em>y = 4x - 7</em>

2). <em>y = 2x - 14</em>

3). <em>y = 2x - 8</em>

4). <em>y = 12x + 9</em>

Zepler [3.9K]

Answer:

1000

Step-by-step explanation:

You are solving for the hundreds place. Find the tens place. It is a 5. Note that when the digit is 5 & up, round up. If 4 and down, round down.

954 rounded to the nearest hundreds place is 1000.

F(1)=-12, f(n)=2f(n-1) <br> find first 4 terms
amid [387]
<h3>First four terms are:   -12, -24, -48, -96</h3>

============================================

Explanation:

The notation f(1) = -12 tells us that the first term is -12.

The equation f(n) = 2*f(n-1) indicates that we're multiplying the (n-1)th term by 2 to get the nth term. Basically we multiply each term by 2 to get the next term.

-12*2 = -24

-24*2 = -48

-48*2 = -96

So the first four terms are -12, -24, -48, -96.

-----------------------------------

Alternative Approach

f(1) = -12 .... first term

f(n) = 2*f(n-1) ... nth term recursive formula

f(2) = 2*f(2-1) ... plug in n = 2

f(2) = 2*f(1)

f(2) = 2*(-12) ... plug in f(1) = -12

f(2) = -24 ... second term

f(n) = 2*f(n-1) .... resetting for the next computation

f(3) = 2*f(3-1) ... plug in n = 3

f(3) = 2*f(2)

f(3) = 2*(-24)  ... plug in f(2) = -24

f(3) = -48 .... third term

f(n) = 2*f(n-1) ... one more reset

f(4) = 2*f(4-1) .... plug in n = 4

f(4) = 2*f(3)

f(4) = 2*(-48) ... plug in f(3) = -48

f(4) = -96 ... fourth term

We get the first four terms to be -12, -24, -48, -96, which was the same as earlier.

Kate has 48 softballs. She wants to divide them evenly among b softball bags. Which expression represents how many softballs she
SOVA2 [1]

Answer:

Softballs = (48/b)

Step-by-step explanation:

Given that,

Total number of softballs = 48

She wants to divide them evenly among b softball bags.

We need to find an expression that represents how many softballs she should put into each bag.

As it is dividing among b softball, it means we divide 48 and b. So,

s=\dfrac{48}{b}

Hence, the required expression is (48/b).
