The solution to the equation is 39.71

Explanation:
The objective to solve any equation is to get the variable alone. In this case we want to isolate p by getting rid of all the numbers on that suede of the equation an moving it to the other side. We want to get rid of the -6.71, so we add 6.71 to both sides of the equation. 33 + 6.71 = p - 6.71 + 6.71, therefore we get 39.71 = p.

Factor the quadratic expression in the equation y=2x^2+28x+96 and use the factors to find the zeros of the equation. Then, use t

gavmur [86]

Answer:

$x=-7$

Step-by-step explanation:

We have been given an equation $y=2x^2+28x+96$ . We are asked to find the zeros of equation by factoring and then find the line of symmetry of the parabola.

Let us factor our given equation as:

$2x^2+28x+96=0$

Dividing both sides by 2:

$x^2+14x+48=0$

Splitting the middle term:

$x^2+6x+8x+48=0$

$(x^2+6x)+(8x+48)=0$

$x(x+6)+8(x+6)=0$

$(x+8)(x+6)=0$

Using zero product property:

$(x+8)=0\text{ (or) }(x+6)=0$

$x+8=0\text{ (or) }x+6=0$

$x=-8\text{ (or) }x=-6$

Therefore, the zeros of the given equation are $x=-8\text{ (or) }x=-6$ .

We know that the line of symmetry of a parabola is equal to the x-coordinate of vertex of parabola.

We also know that x-coordinate of vertex of parabola is equal to the average of zeros. So x-coordinate of vertex of parabola would be:

$\frac{-8+(-6)}{2}=\frac{-14}{2}=-7$

Therefore, the equation $x=-7$ represents the line of symmetry of the given parabola.

Is a tray with a circumference of 32 inches is big enough to

yKpoI14uk [10]

Answer:

Yes

Step-by-step explanation:

Circumference formula is C=2 pi r, if you divide the pizza by 2 to get the radius,5, then input it into the formula to get 31.41592654, and since this number is smaller than 32 it will fit. If 10 is the radius it will not fit.

Review the federal income tax table.

evablogger [386]

Answer:

Step-by-step explanation:

Tax payable:

= $4,543+($41,000-$39,476)×22%

= $4,543+$335.28

= $4,878.28

Tax rate:

= $4,878.28/$41,000

= 11.9%

<em>Hence, Tax rate is 11.9%</em>
