Answer:

4x^2 -34x+42

Step-by-step explanation:

(4x-6)(x-7)

FOIL

first 4x*x = 4x^2

outer 4x*-7 = -28x

inner : -6 *x = -6x

last : -7*-6 = 42

Add them together = 4x^2 -28x-6x +42

                                =4x^2 -34x+42

zimovet [89]

From the coordinate plane, the podium that could be located relative to the center will be B. 288 feet west.

<h3>Coordinate plane</h3>

From the complete information, there is a park in Washington and the event planner plots the park on a coordinate plane.

The table contains points along the perimeter of the park. Since the event planner wants to put a podium at one of the foci, the point where the podium could be located relative to the center will be 288 feet west.

13. Find the equations of the straight lines which passes
ipn [44]

9514 1404 393

Answer:

  • y = 1/2x +2
  • y = -2x +7

Step-by-step explanation:

The slope of a line is the tangent of the angle it makes with the x-axis. The given line has a slope of -1/3, so the lines we want will have slopes of ...

  m1 = tan(arctan(-1/3) +45°) = 0.5 . . . . . using a calculator

  m2 = tan(arctan(-1/3) -45°) = -2

Of course, these two lines are perpendicular to each other, so their slopes will have a product of -1: (0.5)(-2) = -1.

__

We can use the point-slope form of the equation for a line to write the desired equations:

  y = m(x -h) +k . . . . . line with slope m through point (h, k)

<u>Line 1</u>:

  y = 1/2(x -2) +3

  y = 1/2x +2

<u>Line 2</u>:

  y = -2(x -2) +3

  y = -2x +7

A 150-N bird feeder is supported by three cables. Find the tension in each cable.
Irina-Kira [14]
X axis : -t1 cos 60 + t2 cos 60 = 0
 
            t2 cos 60   = t1 cos 60    ; t2   = t1

Y axis : t1 sin 60  + t2 sin 60 - 150 = 0

since t2 = t1

2t1 sin 60 =  150

t1 ( sqrt(3)/2)  = 150/2

t1   = 50 [sqrt(3)]

t2 = 50 [sqrt(3)]

t3 = 150 N

hope this helps
