What is true about this shape?

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:

<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 options are not given, so I will answer in a general way:

A quadratic equation can be written, in general form, as:

y = a*x^2 + b*x + c

Then if we want this, we need to replace:

a = 1

b = -3

c = -5

Then the equation that we want is:

y = x^2 - 3*x - 5

Is likely that the options are in the factorized way to write a quadratic equation (so it is kinda harder to you)

Such that the factorized way is written as:

y = (x - k)*(x - h)

where k and h are the roots of the quadratic equation.

So you just need to expand that expression and find the one that looks like:

y = x^2 - 3*x - 5

Just to be complete, let's find the factorized form of this particular quadratic equation.

The roots are given by:

0 = x^2 - 3*x - 5

And the two solutions are given by Bhaskara's formula:

[tex]x = \frac{-(-3) \pm \sqrt{(-3)^2 - 4*1*(-5)} }{2*1} = \frac{3 \pm 5.39}{2}[/tex]

The two roots are:

h = (3 + 5.39)/2 = 4.195

k = (3 - 5.39)/2 = -1.195

Then the factorized form is:

y = (x - 4.195)*(x + 1.195)

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 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:

y=2x+1

--------------------------------------------------------------------------------------------------------------

Rearrange 2x+3y=15 by subtracting 2x by both sides. Dividing 3y by both sides.

1⇒[tex]2x-2x+3y=15-2x[/tex]

2⇒[tex]\frac{3y=15-2x}{3y}[/tex]

[tex]y=5-\frac{2}{3} x[/tex]

We know this slope is negative. Meaning for the perpendicular crossing to work, it must have a positive slope. We know that 3=(1*M)+B. Perpendicular lines will have slopes that are negative reciprocals of one another.

--------------------------------------------------------------------------------------------------------------

We know the slope must be between 1 and 3. We know the base must be between 1 and 3.

Using the slope formula y-y/x-x

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:

Value of x is 92°.

Step-by-step explanation:

The given figure is a cyclic quadrilateral. All the sides of the quadrilateral touches the circle. So, the sum of the opposite angles will always be 180°.

88° + x° = 180°

x° = 180° - 88°

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.

If it were to be un-defined/infinite then it would be parallel to the y axis

If it were to be 0 then a line would be parallel to the x axis.

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
