Which of the following is not a quadrilateral??

1.hexagon
2.rhombus
3. square
4. trapezoid

Answer:

[tex] x = \boxed{2}\: and\: x = \boxed{ \frac{5}{2} } [/tex]

Step-by-step explanation:

[tex]2 {x}^{2} - 9x + 10 = 0 \\ \\ 2 {x}^{2} - 4x - 5x + 10 = 0 \\ \\ 2x(x - 2) - 5(x - 2) = 0 \\ \\ (x - 2)(2x - 5) = 0 \\ \\ x - 2 = 0 \: \: 2x - 5 = 0 \\ \\ x = \boxed{2} \: and \: x = \boxed{ \frac{5}{2} } \\ \\ [/tex]

Answer:

The measure of a central angle of a circle that intercepts a 68° arc

Step-by-step explanation:

Recall the inscribed angle theorems:

Measure of central angle = measure of intercepted arc

Measure of inscribed angle = ½(measure of intercepted arc)

Therefore,

The measure of a central angle that intercepts a 68° arc = 68°

Measure of an inscribed angle of a circle that intercepts a 68° arc = ½(68°) = 34°

Therefore, the larger would be:

The measure of a central angle of a circle that intercepts a 68° arc

Answer:

<U = 30

Step-by-step explanation:

Since the triangles are similar

<F = <T

<G = <U

< H = <V

We are told that <G = 30 so < U = 30

Answer:

30°

Step-by-step explanation:

∠G corresponds to ∠U

if ∠G is 30° then so is ∠U

Answer:

The median is 19.45

Step-by-step explanation:

Organize the numbers from least to greatest

16.3, 17.8, 17.8, 18.0, 18.7, 19.3, 19.6, 20.1, 20.5, 21.9, 25.2, 25.4

Find the middle of the set of numbers

19.3 and 19.6

Add 9.3 and 19.6

19.3 + 19.6=

38.9

Divide by 2

38.9/2

Which is 19.45

Hope this helps

Answer:

y = 5/8x + 17/4

Step-by-step explanation:

y2 - y1 / x2 - x1

3 - 8 / -2 - 6

5/8

y = 5/8x + b

3 = 5/8(-2) + b

3 = -5/4 + b

17/4 = b

Answer:

x = 0

x = 1/2

Step-by-step explanation:

4x(2x-1) = 0

4x = 0

x = 0

2x-1 = 0

2x = 1

x = 1/2

Answer:

Step-by-step explanation:

8[tex]x^{2}[/tex]-4x=0

4x(x-1)=0

either 4x=0                   Or, x-1=0

x=0/4                                     x=0+1

x=0                                         x=1    

Answer:

k = 12

Step-by-step explanation:

(x^2 + 16x + 64) - (x^2 + 4x - 32)

distributing - 1

x^2 +16r + 64 - x^2 - 4x + 32

12x +96

take a factor of 12

12(x + 8)

K = 12

Step-by-step explanation:

A polygon is a closed figure whose sides are all line segments. A Polygon cannot have curved sides. And Quadrilaterals have four sides closed . all quadrilaterals are polygon but all polygons are not quadrilateral.

Answer:

a) Parabola opens up

b) 6

c) -3/2 and -2

Step-by-step explanation:

a) The general form of a parabolic graph is;

y = ax^2 + bx + c

if a is positive, it faces up, if negative, it opens down

Since a = 2 here, it is positive and thus the parabola faces or opens up

b) The y-intercept is simply the c term

the value here is 6

The y intercept is obtained when the x value is zero

So by simply setting the x value to zero, we can easily get the y value since x is zero at that point

c) The x-intercepts refer to the roots of the equation

By solving the quadratic equation i.e substituting 0 for y, we can get the two x values as follows;

2x^2 + 7x + 6 = 0

2x^2 + 4x + 3x + 6 = 0

2x(x + 2) + 3(x + 2) = 0

(2x + 3)(x + 2) = 0

2x + 3 = 0 or x + 2 = 0

2x = -3 or x = -2

x = -3/2 or x = -2

Answer:

Let x=number of $0.25 increases, so the equation for revenue=price*number of tickets or people) becomes

Revenue=($3.00+$0.25x)(400-20x)

where ($3.00+$0.25x) :increase in price

and

(400-10x) : decrease in number of people

Expanding Revenue

Revenue[R]=1200-60x+100x-5x²:1200+40x-5x²

Taking the derivative of R and set it equal to 0:

R'=0+40-10x=40-10x

we have

R'=0

40-10x=0

x=40/10

x=4

So the ticket price is $3.00+$0.25*4=$4

The number of people will attend is 400-20*4=$320

At $320 ticket price will the revenue be maximized.

Step-by-step explanation:

A $320 ticket price will the revenue be maximized

Answer:

The school can build 2640 clasrooms theorethicly that are 4 feet apart,

but if each clasroom is next to another one that means it is separated by 2 walls then it would be 1320 classrooms

Step-by-step explanation:

2 x 5280 = 10560

10560/4 = 2640

And if the clasroom on each side has to be seperated by walls then

10560 /8= 1320

Answer:

i x 2 x5,280

Answer:

Negative

Step-by-step explanation:

If it is tilted in that sort of way it is negative, vice versa if it was titled the other way then it would be positive.
