Solutions

⇒15 Cookie to 40 brownies can be written as 15:40

⇒15:40 is the ratio we have to simplify

The GCF of 15 and 40 is 5 so we divide them by 5

15 ÷ 5 = 3
40 ÷ 5 = 8

3:8 is in simplest form

The curve with equation y=e^2x/4+3e^x has one stationary point.find the exact value of the coordinates of this point

Softa [21]

$y=\dfrac{e^{2x}}{4+3e^x}$
$\implies y'=\dfrac{2e^{2x}(4+3e^x)-3e^xe^{2x}}{(4+3e^x)^2}$
$\implies y'=\dfrac{8e^{2x}+3e^{3x}}{(4+3e^x)^2}$

Stationary points occur where the derivative is zero. The denominator is positive for all $x$ , so we only need to worry about the numerator.

$8e^{2x}+3e^{3x}=e^{2x}(8+3e^x)=0$

$e^{2x}>0$ for all $x$ , so we can divide through:

$8+3e^x=0\implies e^x=-\dfrac83$

But $e^x>0$ for all $x\in\mathbb R$ , so this function has no stationary points...

I suspect there may be a typo in the question.

Complete the table using the equation y = 9x + 8.

Volgvan

Answer:

$Y = ( -1) | 8 | 17 | 26 | 35|$

Step-by-step explanation:

$y = 9x + 8 \\ \\ \\ x = ( - 1) \\ y = 9( - 1) + 8 \\ y = - 9 + 8 = - 1 \\ \\ x = 0 \\ y = 9(0) + 8 \\ y = 0 + 8 = 8 \\ \\ x = 1 \\ y = 9(1) + 8 \\ y = 9 + 8 = 17 \\ \\ x = 2 \\ y = 9(2) + 8 \\ y = 18 + 8 = 26 \\ \\ x = 3 \\ y = 9(3) + 8 \\ y = 27 + 8 = 35 \\ \\ \\ Y = ( - 1) | 8 | 17 | 26 | 35|$

Answer:

Step-by-step explanation:

2^(-3) = 1/2^3 = 1/8

A minus means put the number in the numerator if it was in the denominator.

A minus means put the number in the denominator it was in the numerator.

If there is no denominator, create one.
