<h3>Answer: 2.25</h3>

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

Explanation:

Multiply the values in the second and third columns. Do this row by row.

Row1: 3*20 = 60

Row2: 2*12 = 24

Row3: 1*6 = 6

Row4: 0*2 = 0

Add up the products to get 60+24+6+0 = 90

Then divide this by the total frequency 20+12+6+2 = 40 to get 90/40 = 2.25

Let f(x) = Square root of 6x and g(x) = x - 3. What's

atroni [7]

For this case we have the following equations:

$f (x) = \sqrt {6x}\\g (x) = x-3$

We must find $(f_ {o} g) (x):$

By definition of composition of functions we have to:

$(f_ {o} g) (x) = f (g (x))$

So:

$(f_ {o} g) (x) = \sqrt {6 (x-3)}$

We must find the domain of f (g (x)). The domain will be given by the values for which the function is defined. That is to say:

$6 (x-3) \geq0\\(x-3) \geq0\\x \geq3$

Then, the domain is given by [3, ∞)

Answer:

The smallest number that is the domain of the composite function is 3

PLEASEE HELPP

stiv31 [10]

Answer:

Step-by-step explanation:

From the given table, we have:

$y_{2}=4x^2$

⇒ $a=4(1)^2$

⇒ $a=4$

$y_{3}=4^x$

⇒ $b=4^1$

⇒ $b=4$

$y_{1}=4x$

⇒ $c=4(2)$

⇒ $c=8$

$y_{3}=4^x$

⇒ $d=4^2$

⇒ $d=16$

$y_{1}=4x$

⇒ $e=4(3)$

⇒ $e=12$

$y_{2}=4x^2$

⇒ $f=4(3)^2$

⇒ $f=36$ and

$y_{3}=4^x$

⇒ $g=4^3$

⇒ $g=64$

Therefore, the value of a,b,c,d,e,f and g is 4,4,8,16,12,36 and 64 respectively.

The value of k such that (x-5) divides the polynomial p(x)= x^3-6x^2+kx+30 exactly,is

mixas84 [53]

Answer:

k = - 1

Step-by-step explanation:

If (x - 5) is a factor of p(x) then p(5) = 0

p(5) = 5³ - 6(5)² + 5k + 30 = 0 , that is

125 - 150 + 5k + 30 = 0

5 + 5k = 0 ( subtract 5 from both sides )

5k = - 5 ( divide both sides by 5 )

k = - 1
