Answer:

Step-by-step explanation:

Given equation is,

a). y = $\frac{6}{x}$

x 0.5 1 2 3 4 5 6

y $\frac{6}{0.5}=12$ $\frac{6}{1}=6$ $\frac{6}{2}=3$ $\frac{6}{3}=2$ $\frac{6}{4}=1.5$ $\frac{6}{5}=1.2$ $\frac{6}{6}=1$

b). By plotting the input-output values on the graph we get the curve as shown in option C.

Therefore, Option C will be the answer.

Verify that the function satisfies the three hypotheses of Rolle's Theorem on the given interval. Then find all numbers c that s

WINSTONCH [101]

Answer: $\bold{c=\dfrac{1+\sqrt{19}}{3}\approx1.8}$

<u>Step-by-step explanation:</u>

There are 3 conditions that must be satisfied:

f(x) is continuous on the given interval
f(x) is differentiable
f(a) = f(b)

If ALL of those conditions are satisfied, then there exists a value "c" such that c lies between a and b and f'(c) = 0.

f(x) = x³ - x² - 6x + 2 [0, 3]

1. There are no restrictions on x so the function is continuous $\checkmark$

2. f'(x) = 3x² - 2x - 6 so the function is differentiable $\checkmark$

3. f(0) = 0³ - 0² - 6(0) + 2 = 2

f(3) = 3³ - 3² - 6(3) + 2 = 2

f(0) = f(3) $\checkmark$

f'(x) = 3x² - 2x - 6 = 0

This is not factorable so you need to use the quadratic formula:

$x=\dfrac{-(-2)\pm \sqrt{(-2)^2-4(3)(-6)}}{2(3)}\\\\\\.\quad =\dfrac{2\pm \sqrt{4+72}}{2(3)}\\\\\\.\quad =\dfrac{2\pm \sqrt{76}}{2(3)}\\\\\\.\quad =\dfrac{2\pm 2\sqrt{19}}{2(3)}\\\\\\.\quad =\dfrac{1\pm \sqrt{19}}{3}\\\\\\.\quad \approx\dfrac{1+4.4}{3}\quad and\quad \dfrac{1-4.4}{3}\\\\\\.\quad \approx1.8\qquad and\quad -1.1$

Only one of these values (1.8) is between 0 and 3.

1. Jin bought 3 small candles and 1 medium candle for $3.85. Trish bought 4 small candles and 5 medium candles for $10.45. Write

Ivanshal [37]

Hi, thank you for posting your question here at Brainly.

Jin: 3 small candles and 1 medium candle
3s + 1m = 3.85 <-- equation 1

Trish: 4 small candles and 5 medium candles
4s + 5m = 10.45 <-- equation 2

Solving the system of equations,

s = $0.8/small candle
m = $1.45/medium candle
