G(x) = x^2 + 3x - 4

= x^2 + 4x - x - 4

= x(x+4) - (x+4)

= (x-1)(x+4)

so the zeros are x1=-4 and x2=1 in ascending order

vertex is at mid-pt of zeros so its x is (-4+1)/2 = -3/2

put back into g(x) = x^2 + 3x - 4, y = g(-3/2) = -25/4

so vertex is (-1.5, -6.25)

line of symmetry is at vertex x=-1.5

The area of a rectangular tennis court is 140 square meters. It's length is 6 meters less than twice it's width. Find the dimens
Whitepunk [10]

Answer: length = 14 meters

Width = 10 meters

Step-by-step explanation:

The rectangular tennis court has two equal lengths,L and two equal widths,W

The area of the tennis court is expressed as

Area = Length × width

The area is given as 140 square meters. It means that

L× W = 140

It's length is 6 meters less than twice it's width. It means that

L = 2W - 6

Substituting L = 2W - 6 into LW = 140, it becomes

W(2W - 6) = 140

2W^2 - 6W = 140

2W^2 - 6W - 140 = 0

W^2 - 3W - 70 = 0

W^2 + 7W - 10W - 70 = 0

W( W + 7 ) - 10( W + 7) = 0

( W + 7 )(W - 10) = 0

( W + 7 ) = 0 or W - 10 = 0

W= -7 or W = 10 meters

The value cannot be negative so W = 10

L = 2W - 6 = 2×10 - 6

L = 20 - 6 = 14 meters

Find the area of the trapezoid.
ss7ja [257]

\bf \textit{area of a trapezoid}\\\\
A=\cfrac{h(a+b)}{2}~~
\begin{cases}
a,b=\stackrel{bases}{parallel~sides}\\
h=height\\[-0.5em]
\hrulefill\\
a=15.8\\
b=21.8\\
h=11.7
\end{cases}\implies A=\cfrac{11.7(15.8+21.8)}{2}
\\\\\\
A=\cfrac{11.7(37.6)}{2}\implies A=219.96

You're sitting on the ledge of a wall that is 300 feet away from a building. You have to
weeeeeb [17]

The total height of the building in question is;

600 ft

<h3>Angle of Elevation</h3>

The ledge of a wall is simply a projection from a building.

Now, we are told that this ledge is 300 ft from the building.

  • Angle of elevation to the building top = 60°
  • Angle of depression to the building bottom = 15°

Now, from the attached image, the distance from the ledge on the building wall to the top of the building is x.

  • Thus, by trigonometric ratio;

x/300 = tan 60

x = 300 × 1.732

x ≈ 520 ft

  • Similarly, via trigonometric ratio;

y/300 = tan 15

y = 300 × 0.2679

y ≈ 80

Thus;

Height of building = 520 + 80

Height of building = 600 ft
