You will get

2A- 12 6

2 10

3B- 9 3

-12 -6

you will then have to subtract the two matrices and you will get

- 3 3

Oi 

Just calculating the differential. Step by step:

y=12 \sqrt{x} -x \frac{3}{2}-10 \\  \\ y=12x^{ \frac{1}{2} } -x \frac{3}{2}-10 \ \ \ \boxed{transform \  \sqrt{x} =x^{ \frac{1}{2} }}  \\  \\  Differentiating \\  \\ y'=12. \frac{1}{2}.x^{ \frac{1}{2}-1 } -1.x^{1-1}. \frac{3}{2}-0 \\  \\  y'=6.x^{ -\frac{1}{2} } -x^{0}. \frac{3}{2} \\  \\  y'=6. \frac{1}{x^{ \frac{1}{2} }}  -1. \frac{3}{2}  \\  \\  \boxed{y'=\frac{6}{ \sqrt{x} }  -\frac{3}{2}}

If you want to know where the tangent has no slope:

\frac{6}{ \sqrt{x} } - \frac{3}{2} =0 \\  \\  \frac{6}{ \sqrt{x} } = \frac{3}{2}  \\  \\ 3 \sqrt{x} =12 \\  \\  \sqrt{x} = \frac{12}{3}  \\  \\  \sqrt{x} =4 \\  \\   (\sqrt{x})^2 =4^2 \\  \\ x=16

Use the Pythagorean Theorem to find which one of the
marissa [1.9K]
<h3>Hello There!!</h3>

<h3><u>Given</u>:-</h3>

Altitude (AB) = 9cm

Base (BC) = 12cm

<h3><u>To </u><u>Find</u></h3>

Hypotenuse (AC) = ?

\fbox \text{According To Pythagoras Theorem = }

\text{(Hypotenuse)² = (Altitude)² + (Base)²}

Inserting The Values

\text{(Hypotenuse)²} =(  {9})^{2}  + (12) {}^{2}  \\  \\  \implies  \text{(AC)} {}^{2}  = 81 + 144 \\  \\  \implies  \text{(AC}) {}^{2}  = 225 \\  \\  \implies  \text{AC} =  \sqrt{225}  \\  \\  \implies \text{AC} = 15

\therefore \text{Hypotenuse \: (AC)} = 15 \text{cm}

Option B= <em>15cm</em> is the <u>correct answer</u>

Help with #1 please?
anygoal [31]
7/9 + 5/6 + 3 2/3
7/9 + 5/6 + 11/3
Common denominator is 18 so we get
14/18 + 15/18 + 66/18
= 95/18 cups of milk
Multiply this by 3 (since he uses 1/3 cups per latte)
= 285/18 = 15 15/18 = 15 5/6 cups of latte
