Answer:

14√6.

Step-by-step explanation:

√54 = √9√6 = 3√6

√486 = √81 √6 = 9√6.

√24 = √4√6 = 2√6.

So √54 + √486 + √24

= 3√6 + 9√6 + 2√6

= 14√6.

Answer: 2d³+11d²+19d+10

Step-by-step explanation:

Use the FOIl method to simplify this

First
Outer
Inner
Last

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

(5+2d)(2+3d+d²)

=10+15d+5d²+4d+6d²+2d³ ⇔ Expand using FOIL

=2d³+(5d²+6d²)+(4d+15d)+10 ⇔ Put like terms together

=2d³+11d²+19d+10 ⇔ Combine like terms

Hope this helps!! :)

The functions f and g are differentiable for all real numbers x. The table below gives values for the functions and their first

sertanlavr [38]

Answer:

13/9

y =-22x+32

Step-by-step explanation:

Given that the functions f and g are differentiable for all real numbers x. The table below gives values for the functions and their first derivatives at selected values of x.

x f(x) f'(x) g(x) g'(x)

1 4 -3 5 2

2 -3 -1 4 6

3 π 8 -1 4

4 -5 unknown 0 3

a) $h(x) = \frac{f(x)}{g(x)} \\h'(x) = \frac{g(x)f'(x)-f(x)g'(x)}{(g(x))^2}$

(using quotient rule)

Substitute 1 for x

$h'(1) = \frac{g(1)f'(1)-f(1)g'(1)}{(g(1))^2}\\=\frac{9-(-4)}{9} \\=\frac{13}{9}$

b) $r(x) = f(x) g(x)\\r'(x) = f(x) g'(x)+g(x)f'(x)$

when $x =2, r(x) = r(2) = f(2) g(2) = -12$

point of contact is (2,-12)

Slope of tangent = $r'(2) = f(2) g'(2)+g(2)f'(2)\\=-18+(-4) \\=-22$

Using point slope form, tangent is

$y+12 = -22(x-2)\\y = -22x +32$
