Answer:

At the positive integer value of x=7 the quadratic function begin to exceed the linear function

Step-by-step explanation:

we have

using a graphing tool

see the attached figure

For x < -1.405 and x > 6.405 the quadratic function begin to exceed the linear function

so

At the positive integer value of x=7 the quadratic function begin to exceed the linear function

Step-by-step explanation:

Alexis is making cookies. The recipe says that she has to mix 192 grams of sugar into the flour. Alexis knows that 1 cup of this
Dmitrij [34]
For this case we can make the following rule of three:
 1 cup ----------------> 128 grams
 x ----------------------> 192 grams
 From here, we clear the value of x.
 We have then:
 x = (192/128) * (1)
 x = 1.5
 x = 1 1/2
 Answer:
 
She needs about 1 1/2 cups.

What polynomial expressions equal 8x^3+64?
Natali5045456 [20]

Answer:

\displaystyle \boxed{8[x + 2][x^2 - 2x + 4]}

Step-by-step explanation:

Use the Difference of Cubes [(a³ - b³)(a² + 2ab + b²)] to figure this out:

\displaystyle 8x^3 + 64 \\ 8[x^3 + 8] \\ \\ x + 2 = \sqrt[3]{x^3 + 8}

Then, since the divisor\factor is in the form of <em>x - c</em>, use what is called Synthetic Division. Remember, in this formula, −c gives you the OPPOSITE terms of what they really are, so do not forget it. Anyway, here is how it is done:

−2| 1 0 0 8

↓ −2 4 −8

___________

1 −2 4 0 → {x}^{2} - 2x + 4

You start by placing the <em>c</em> in the top left corner, then list all the coefficients of your dividend [x³ + 8]. You bring down the original term closest to <em>c</em> then begin your multiplication. Now depending on what symbol your result is tells you whether the next step is to subtract or add, then you continue this process starting with multiplication all the way up until you reach the end. Now, when the last term is 0, that means you have no remainder. Finally, your quotient is one degree less than your dividend, so that 1 in your quotient can be an x², the −2x follows right behind it, then 4, giving you the other factor of x^2 - 2x + 4, attaching this to the first two factors you started out your work on:

\displaystyle \boxed{8[x + 2][x^2 - 2x + 4]}

I am joyous to assist you anytime.

Please help as soon as possible
Aleks [24]

Answer:

c= 12.19

Step-by-step explanation:

Let's solve for c.

5.3(4x−2.3)=21.2x+c

Step 1: Flip the equation.

c+21.2x=21.2x−12.19

Step 2: Add -21.2x to both sides.

c+21.2x+−21.2x=21.2x−12.19+−21.2x

c=−12.19

Answer:

c=−12.19
