Remmeber yo can do antyhing to an equation as long as you do it to both sides

9x>270
divide both sides by 9
x>30


B/4<4
times both sides by 4
B=16


Y/5≤8
times both sides by 5
Y≤40



5c≥125
divide both sides by 5
c≥25

Faelyn grouped the terms and factored the GCF out of the groups of the polynomial 6x4 – 8x2 + 3x2 + 4. Her work is shown. Step 1
fiasKO [112]

Answer:

B. Faelyn should realize that her work shows that the polynomial is prime

Step-by-step explanation:

The polynomial 6x⁴ – 8x² + 3x² + 4 needs to be factored and the steps are:

Step 1: (6x⁴ – 8x²) + (3x² + 4)

Step 2: 2x²(3x² – 4) + 1(3x² + 4)

Since they do not have a common factor, Faelyn should realize that her work shows that the polynomial is prime. A prime polynomial cannot be factored further because it is at its lowest common term and cannot be factored into any other polynomial of a lower degree. Prime polynomials have integer coefficients. A prime polynomial is also referred to as an irreducible polynomial.

A. A container holds 0.500 qt of liquid. How many milliliters of lemonade will it hold?
Nady [450]

Answer:

<em>A container can hold 473.176 ml</em>

<em>42.52 grams is nitrogen. </em>

Step-by-step explanation:

<u>Part A:</u>

We have given that a container holds 0.500 qt . Now we have to find how many milliliters of lemonade it can hold.

We know that 1 qt = 946.353 ml

To find how many milliliters of lemonade a container hold, we have to convert 0.500qt into ml.

As we have mentioned above that 1 qt = 946.353 ml

Multiply the volume value by 946.353 .

0.500 * 946.353

= 473.176 ml

<em>It means a container can hold 473.176 ml</em>

<u>Part B:</u>

Convert the unit oz  to grams. The ratio is 1 ounce is to 28.34 grams.

We have 10.0 oz.

10* 28.34 = 283.495

This would mean 10 oz is equivalent to 283.50 grams. It is given that the fertilizer is 15% by mass nitrogen. It means for every 100 g of fertilizer 15 grams of that is nitrogen. Hence for every 283.50 grams of fertilizer

<em>283.50 * (15/100) = 42.52 grams is nitrogen. </em>

At what point on the graph of y=1/4x^4 is the tangent line parallel to the line 24x -3y=8
Rama09 [41]

Answer:

a) dy/dx = 4/(2y+1)^2.

(b) y = 4/9 x - 14/9

(c) d2y/dx2 = -64/243

Step-by-step explanation:

You have the following equation

  (1)

(a) You first derivative implicitly the equation (1) respect to x:

next, you solve the last result for dy/dx:

(2)

(b) The equation for the tangent line is given by:

   (3)

with yo = -2 and xo = -1

To find the slope m you use the result of the equation (2), because dy/dx evaluated in (-1,-2) is the slope at such point:

m =

Hence, by replacing in the equation (3) you obtain:

hence, the equation for the tangent line is y = 4/9 x - 14/9

(c) To find d2y/dx2 you derivative the result obtain in the equation (2):

    (4)

the second derivative for the point (-1,-2) is obtained by replacing y=-2 and dy/dx=m=4/9 in the equation (4):

hence, d2y/dx2 evaluated in (-1,-2) is -64/243

A hovercraft takes off from a platform. Its height (in meters), xx seconds after takeoff, is modeled by: h(x)=-2x^2+20x+48h(x)=?
tangare [24]

Answer: 5 seconds

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

Maximum height is the y-value of the vertex. The number of seconds at maximum height is the x-value (aka axis of symmetry).

h(x) = -2x² + 20x + 48

      a=-2    b=20   c=48

Axis of symmetry: x = \frac{-b}{2a}

                                 = \frac{-20}{2(-2)}

                                 = \frac{-20}{-4}

                                 = 5
