If y varies directly with x, and y = 18 when x = 4, what is the constant of proportionality?

1 answer:

3 0

Y is directly proportional to x and therefore takes the form y=kx where k is the constant of proportionality.

Dividing both sides by x for the given values, k becomes 18/4 = 4.5

Factor the perfect-square trinomial in y = (x2 + 2x + 1) − 1− 1.<br> y = (x + <br> )2 − 1 −1

♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️

$y = ( {x}^{2} + 2x + 1) - 1$

$y = ({x + 1})^{2} - 1$

$y = ({x + 1})^{2} - ({1})^{2}$

We're done now but I have something to tell...

##############################

Hint :

${a}^{2} - {b}^{2} = (a + b)(a - b)$

##############################

$y = ( \: (x + 1) + 1)( \: (x + 1) - 1) \\$

$y = (x + 2)(x)$

Determine whether the Mean Value Theorem applies to the function f(x)=2x^1/5 on the interval [-32, 32]

Anettt [7]

Answer

given,

$f(x) = 2 x^{1/5}$

interval = [-32, 32]

differentiating the given equation

$f'(x) = \dfrac{d}{dx}(2 x^{1/5})$

$f'(x) = \dfrac{2}{5x^{4/5}}$

hence, the above solution is not defined at x = 0

and x = 0 lie in the given interval i.e. [-32, 32]

so, at x = 0 the function is not differentiable.

Hence, mean value theorem does not apply to the given function.

Answer:

It's 70.4 because i subtracted the 2 numbers and it gave me 9.6 just like 80-9.6. I don't know if i'm right, please correct me if i'm wrong. I'm still not sure...

Step-by-step explanation:

43-123= -80

80-9.6=70.4

80-70.4= 9.6
