Please Help - Suppose f(t)=6t−8−−−−√.

Gnoma [55]

$(a)\\\\\\\text{Given that,}~~\\\\ f(t) =\dfrac 6{\sqrt{t-8}}\\\\\\\\\implies f'(t) = 6\left[\dfrac{\left(\sqrt{t-8}\right) \cdot 0 - \dfrac 1{2\sqrt{t-8 }}}{\left(\sqrt{t-8}\right)^2}\right]\\\\\\\\\implies f'(t) = -6\left(\dfrac {\dfrac 1{2\sqrt{t-8}}}{t-8}\right)\\\\\\\implies f'(t) = -6\left(\dfrac{1}{2\sqrt{t-8} (t-8)}\right)\\\\\\\implies f'(t) =-\dfrac 3{(t-8)^{\tfrac 32}}$

(b)

$\text{Given that,}\\\\y=f(t)\\\\\text{Slope of y,} ~~ f'(t) =-\dfrac 3{(t-8)^{\tfrac 32}}\\\\\text{At point (33, 6/5)}\\\\\\f'(t) = -\dfrac 3{(33-8)^{\tfrac 32}} = - \dfrac 3{ (25)^{ \tfrac 32}} = - \dfrac 3{5^3} = -\dfrac 3{125}\\\\\\\text{Equation with given points,}\\\\y - \dfrac 65 = -\dfrac 3{125} ( t - 33)\\\\\\\implies y =-\dfrac 3{125} t +\dfrac{99}{125} + \dfrac 65\\\\\\\implies y = -\dfrac 3{125} t +\dfrac{249}{125}$

What’s the explanation

Viktor [21]

Answer:

x³ + 2x² - 19x - 20

Step-by-step explanation:

x + 1 = 0

x = -1

Substitute x = (-1) in the polynomial

x³ + 2x² - 19x - 20 = (-1)³ + 2*(-1)² - 19 *(-1) - 20

= -1 + 2 +19 - 20

= -1 - 20 + 2 + 19

= -21 + 21 = 0

So, (x + 10 ix a factor of x³ + 2x² -19x - 20

Answer:

por favor, verifique a explicação

Step-by-step explanation:

Queremos escrever cada um dos números como uma multiplicação de seus fatores; Procedemos da seguinte maneira;

a. 51 = 3 * 17

b. 56 = 2 * 2 * 2 * 7

c. 65 = 5 * 13

d. 77 = 7 * 11

e. 48 = 2 * 2 * 2 * 2 * 3

f. 50 = 2 * 5 * 5

g. 80 = 2 * 2 * 2 * 2 * 5

h. 99 = 3 * 3 * 11

i. 108 = 2 * 2 * 3 * 3 * 3

j. 132 = 2 * 2 * 3 * 11

k. 210 = 2 * 3 * 5 * 7

l. 180 = 2 * 2 * 3 * 3 * 5

m. 234 = 2 * 3 * 3 * 13
