PLEASEEEEEEEE!!! Graciela was trying to solve the quadratic equation

"TexFormula1" title="x^2+2.5x-1.5=0" alt="x^2+2.5x-1.5=0" align="absmiddle" class="latex-formula">. “I think I need to use the Quadratic Formula because of the decimals,” she told Walter. Walter replied, “I'm sure there's another way! Can't we rewrite this equation so there aren't any decimals?” original equation.
A.What is Walter talking about? Rewrite the equation so that it has no decimals.
B.Rewrite your equation again, this time expressing it as a product.
C.Now solve your new equation. Be sure to check your solution(s) using Graciela's original equation.

A survey team is trying to estimate the height of a mountain above a level plain. From one point on the plain, they observe that
aliya0001 [1]

Answer:

5507.79 feet

Step-by-step explanation:

To find the height of the mountain, we can draw triangles as in the image attached.

Let's call the height of the mountain 'h', and the distance from the first point (31 degrees) to the mountain 'x'.

Then, we can use the tangent relation of the angles:

tan(34) = h/x

tan(31) = h/(x+1000)

tan(31) is equal to 0.6009, and tan(34) is equal to 0.6745, so:

h/x = 0.6745 -> x = h/0.6745

using this value of x in the second equation:

h/(x+1000) = 0.6009

h/(h/0.6745 + 1000) = 0.6009

h = 0.6009 * (h/0.6745 + 1000)

h = 0.8909*h + 600.9

0.1091h = 600.9

h = 600.9 / 0.1091 = 5507.79 feet

Find the volumes of the solids generated by revolving the regions bounded by the graphs of the equations about the given lines.
Nina [5.8K]

Answer:

81π for the x axis.

Step-by-step explanation:

STEP ONE: Determine the intersection.

we are given from the question that y = x^2 and y = 6x − x^2. Therefore if y = x^2, then we will have;

x^2 = 6x - x^2  ---------------------------------------------------------------------------------[1].

Solving and factorizing the equation [1] above give us x = 0 and x = 3 (that is x[6 -2x] = 0 ). Therefore, the point of intersection = (0,0) and (3,9).

<u>STEP TWO</u><em>: </em>Determine the value for the cross sectional area.

The cross sectional area= [6x - x^2]π - [x2]^2 π. --------------[2].

The cross sectional area = -12 π[x -3]x^2.

<u>STEP THREE:</u> integrate the cross sectional area taking x =3 and x =0 as the upper and lower integration limits or boundaries with respect to dx to determine the vome in the x axis.

<h3>volume =∫-12 π[x -3]x^2 dx.</h3><h3 /><h3>volume = -12 π[ (3)^4/4 - (3)^3 ] = 81π.</h3>

volume, v with respect to the x axis = 81π
