Hello There!

First, find the lowest common denominator. The lowest common denominator is 6 so we will rewrite the equation with the equivalent fractions.

$\frac{3}{6}$ + $\frac{4}{6}$ = $\frac{7}{6}$

$\frac{7}{6}$ = 1 $\frac{1}{6}$

Differentiate both sides with respect to x

$\frac{d}{dx}(x^{\frac{1}{2}} + y^{\frac{1}{2}}) = \frac{d}{dx}(1)\\\\ \frac{1}{2x^{\frac{1}{2}}} + \frac{1}{2y^{\frac{1}{2}}}\frac{dy}{dx} = 0\\\\\frac{1}{2y^{\frac{1}{2}}}\frac{dy}{dx} = -\frac{1}{2x^{\frac{1}{2}}}\\\\\frac{1}{2\sqrt{y}}\frac{dy}{dx} = -\frac{1}{2\sqrt{x}} \\\\\frac{dy}{dx} = -\frac{1}{2\sqrt{x}} \times 2\sqrt{y}\\\\\frac{dy}{dx} = -\frac{\sqrt{y}}{\sqrt{x}} \\\\\boxed{\bf{y'= -\frac{\sqrt{y}}{\sqrt{x}}}}$

mixer [17]

Answer:

A. 5/72

Step-by-step explanation:

5 + 4 + 3 = 12 marbles

5/12 - the probability that the student picks a blue marble.

1/6 - the probability that 4 is on the cube

The probability that the student picks a blue marble from the bag, and then rolls a 4

5/12 * 1/6 = 5/72

A company that makes hair care products at 9000 people try a new shampoo. Of the 9000 people, 18 had a mid allergic reaction. Wh

lara [203]

Answer:

0.2% of the people had mid allergic reaction.

Step-by-step explanation:

Given that:

Number of people tested for a new shampoo = 9000

Number of people who had allergic reaction = 18

Percent of people = $\frac{People\ who\ have\ reaction}{Total\ number}*100$

Percent of people = $\frac{18}{9000}*100$

Percent of people = 0.002 * 100

Percent of people = 0.2%

Hence,

0.2% of the people had mid allergic reaction.

The function f(x) = −x2 + 50x − 264 models the profit, in dollars, a yoga studio makes for selling monthly memberships, where x

Marina CMI [18]

The given function is $f(x) = -x^2 + 50x - 264$ . This is a quadratic function because the degree of the polynomial, the variable with the highest exponent, is 2.

All quadratic functions can be expressed in the form $f(x) = ax^2 + bx + c$ .
In your equation,
a = -1
b = 50
c = -264

The equation for the x-coordinate vertex of a quadratic function is $x = \frac{-b}{2a}$ .
Applying this to the given function,
$x = \frac{-(50)}{2(-1)} = \frac{50}{2} = 25$ .

Now plug the value of x into f(x) to find f(x) (aka the y-coordinate).
$f(x) = -x^2 + 50x - 264 \\
f(25) = -(25)^2 + 50(25) - 264 \\
f(25) = 361$

The vertex is (25, 361)

Part B
The x-intercept is where the graph crosses the x-axis. Therefore, f(x) (aka the y-coordinate) will be 0. So the x-intercept will be in the form of (x, 0).

To find the x-intercept, set f(x) = 0.
$0 = -x^2 + 50x - 264 \\
0 = (x-6)(x-44) \\
x = 6, x = 44$ .

Therefore the x-intercepts will be at (6, 0) and (44, 0)
