Answer:5 vans   7 cars

Step-by-step explanation:

c=cars         v=vans

c+v= 12

c =( 12-v)

11v + 4(12-v) = 83

11v + 48-4v = 83

7v = 35

v= 5

c = 12-5         c = 7

7 cars x 4 students = 28 students

5 vans x 11 students = 55 students

55+28 = 83 students

Answer:

Step-by-step explanation:

First, we know that the sin function is odd which means:

sin(-x) = -sin(x).

Secondly evaluating an inverse trigonometric function with a normal trigonometric function as the argument can be rewritten as an algebraic expression.

Let [tex]t = \sin(-\frac{11\pi}{4}) = - \sin(\frac{11\pi}{4})[/tex]

We know the certain identity.

[tex]\sin(\theta) = \sin(2\pi + \theta)[/tex]

We use it to evaluate sin(11 pi / 4).

[tex]\sin(\frac{11 \pi}{4}) = \sin({\frac{8\pi}{4} + \frac{3 \pi}{4}}) = \sin(2\pi + \frac{3 \pi}{4}) = \sin(\frac{3\pi}{4})[/tex]

Another helping identity is the following:

[tex]\sin(\theta) = \sin(\pi - \theta)[/tex]

[tex]\sin(\frac{3\pi}{4}) = \sin(\pi - \frac{3\pi}{4}) = \sin(\frac{\pi}{4}) = \frac{\sqrt{2}}{2}[/tex]

But let's not forget that t = -sin(11 pi/4) = - sqrt(2) / 2

Now we end up with the following equation.

[tex]\cos^{-1}(-\frac{\sqrt{2}}{2}) = x\\\cos(x) = -\frac{\sqrt{2}}{2} => x = \frac{3\pi}{4}[/tex]

Answer:

26

Step-by-step explanation:

For this case we must find the inverse of the following function:

[tex]y = x ^ 2-2[/tex]

We exchange the variables:

[tex]x = y ^ 2-2[/tex]

We clear the variable "y":

Adding 2 to both sides we have:

[tex]x + 2 = y ^ 2[/tex]

Applying square root on both sides of the equation:

[tex]y = \pm \sqrt {x + 2}[/tex]

We change y by [tex]f ^ {- 1} (x)[/tex]:[tex]f ^ {- 1} (x) =\pm \sqrt {x + 2}[/tex]

Answer:

[tex]f ^ {- 1} (x) = \pm\sqrt {x + 2}[/tex]

Answer:

the area of a sector is 151.976 cm²....

Step-by-step explanation:

Area of sector(A)is given by:

A=πr².θ/360°

where,

r is the radius and θ is the angle in degree.

As per the statement:

A central angle of 4π/5 radians and a radius of 11 cm.

r=11cm

Use conversion:

1 radian=180/π

then:

4π/5 radians=180/π * 4π/5

=144°

θ=144°

Substitute these given values and use 3.14 for π we have;

A=3.14*(11)²*144/360

A=3.14(121)*144/360

A=379.94*0.4

A=151.976 cm²

Therefore the area of a sector is 151.976 cm²....

The area of a sector with a central angle of 4π/5 radians and a radius of 11 cm is approximately 96.8 cm², calculated using the formula A = (θ/2π) * πr² and rounded to two significant figures.

To find the area of a sector of a circle with a given central angle in radians and a specific radius, you can use the formula:

A = (θ/2π) * πr²

where A is the area of the sector, θ is the central angle in radians, and r is the radius of the circle.

In this case, the central angle is 4π/5 radians and the radius is 11 cm. Substituting the given values into the formula:

A = (4π/5/2π) * π * (11 cm)²
= (2/5) * π * 121 cm²
= (2/5) * 3.1415927 * 121 cm²
= 96.76 cm² to two significant figures, since the radius is given to two significant figures.

Hence, the area of the sector is approximately 96.8 cm².

      1       4       6      4       1

  1      5      10      10     5       1

As there are 5 lights we need the last row in the above Pascals triangle.

And  there is 1 red and 4 green  ( = 5) and it can happen in 5 ways, so that gives us the second term in the last row . The total  in that last row = 1+5+10+10+5+1 = 32.

Answer:

r = 3

Step-by-step explanation:

x^2 + 6x + y^2 - 8y = - 16

Take half the linear term and square it.

x^2 + 6x + (3)^2 + y^2 - 8y + (-4)^2 = - 16

Add the squared amounts to the right.

x^2 + 6x + 9 + y^2 - 8y + 16 = - 16 + 9 + 16  

Combine on the right.

x^2 + 6x + 9 + y^2 - 8y + 16 = 9

Represent the 2 quadratics as perfect squares.

(x + 3)^2 + y - 4)^2 = 9

The radius is the square root of 9 which is 3

Answer:

radius=3

Step-by-step explanation:

Given:

x^2 +6x +y^2 - 8y=-16

completing the squares

: x^2 +6x +9 = (x+3)^2

:y^2-8y+16 = (y-4)^2

(x+3)^2 + (y-4)^2 -9-16=-16

(x+3)^2 + (y-4)^2=-16+9+16

(x+3)^2 + (y-4)^2=9

Now comparing with standard equation of circle i.e. (x-h)^2 + (y-k)^2=r^2, we get

origin(h,k)= (-3,4)

Answer:

192 pieces of tiles will be required.

Step-by-step explanation:

A customer is tiling a shower's back wall which is in the dimensions of 6' by 4'

This area of the wall is = 6 × 4 square feet = 24 feet²

Customer wants to cover this wall with the tiles measuring 3" by 6" or 3 inches by 6 inches.

Now we will convert these dimensions of the tiles in foot.

Since 12 inches = 1 foot

Therefore, 1 inch = [tex]\frac{1}{12}[/tex] foot

Dimensions of one tile in foot will be [tex]\frac{3}{12}[/tex] foot by [tex]\frac{6}{12}[/tex] foot.

In simplified form, dimensions of the tile is [tex]\frac{1}{4}[/tex] foot by [tex]\frac{1}{2}[/tex] foot.

Area of one tile = [tex]\frac{1}{4}\times \frac{1}{2}=\frac{1}{8}[/tex] square feet

Number of tiles = [tex]\frac{\text{Area of the wall}}{\text{Area of one tile}}[/tex]

                          = [tex]\frac{24}{\frac{1}{8}}[/tex]

                          = 24×8

                          = 192 tiles

Therefore, 192 pieces of tiles will be required.

Answer:

Here's what I get    

Step-by-step explanation:

∆PQR is a right triangle.

PR² = PQ² + QR² = 48² + 64² = 2304 + 4096 = 6400

PR = √6400 = 80  

PQ:QR:PR = 48:64:80 = 3:4:5

We can consider ∆PQR as a 3:4:5 triangle.

[tex]\sin \theta = \dfrac{4}{5} \\\\\cos \theta = \dfrac{3}{5}\\\\\tan \theta = \dfrac{4}{3}\\\\\cot \theta = \dfrac{3}{4} \\\\\csc \theta = \dfrac{5}{4}\\\\\sec \theta = \dfrac{5}{3}[/tex]

Answer:

The formula used for Pythagoras Theorem.

(Hypotenuse)² = (Base)² + (Perpendicular)²

We have

PQ = 48, QR = 64 and PR = ?

⇒ (PR)² = (PQ)² + (QR)²

⇒ (PR)² = (48)² + (64)²

⇒ (PR)² = 2304 - 4096 = 64 00

⇒ PR = 80

The six trigonometric functions we have are:

Answer:

No intersection

Zero intersections

Step-by-step explanation:

Let's determine the slope first.

If the slopes are different, then there is one solution.

If the slopes are the same, there are 2 possibilities.  The first possibility is that there is no solutions because the lines are parallel.  The second possibility is that there is infinitely many solutions because they are the same line. When I say solution, I'm also referring to intersection.

So I'm going to find the slope by lining up the points and subtracting vertically then putting 2nd difference over 1st difference.

Let's do that for line A:

 (  2  ,   8)

- (  -2 , -4)

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

  4        12

So the slope is 12/4 or just 3.

Let's do this for line B now:

  (  4  ,  10)

-  ( -3  ,  -11)

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

    7     21

So the slope is 21/7 or just 3.

So we have more work now. The lines either are the same or parallel.

We are going to use this to determine if they same or parallel, we are going to find the slope-intercept form of the equation for both lines.

That is y=mx+b where m is slope and b is y-intercept.

Let's look at line A:

y=mx+b with m=3 and a point (x,y)=(2,8)

8=3(2)+b

8=6+b

2=b

So the line is y=3x+2

Let's look at line B.

y=mx+b with m=3 and a point (x,y)=(4,10)

10=3(4)+b

10=12+b

-2=b

The equation of this line is y=3x-2

So the lines y=3x+2 and y=3x-2 are not the same, they are parallel which means they intersect zero times.

Answer:

Zero

Step-by-step explanation:

How many points of intersection are there between line A and line B if they contain the points listed?

Line A: (2, 8) and (–2, –4)

Line B: (4, 10) and (–3, –11)

Answer: c) 24.9

Step-by-step explanation:

Use the distance formula then add and round to nearest tenth

The perimeter of the triangle ABC will be 24.9. Then the correct option is C.

Let one point be (x, y) and another point be (h, k).

Then the distance between the points will be

D² = (x – h)² + (y – k)²

The vertices of the triangle are A(1, 3), B(11, 4), and C(7, 9).

The distance between AB will be

AB² = (11 – 1)² + (4 – 3)²

AB² = 101

AB = 10.05

The distance between BC will be

BC² = (11 – 7)² + (4 – 9)²

BC² = 41

BC = 6.40

The distance between AC will be

AC² = (7 – 1)² + (9 – 3)²

AC² = 72

AC = 8.50

Then the perimeter of the triangle ABC will be

Perimeter = AB + BC + CA

Perimeter = 10.05 + 6.40 + 8.50

Perimeter = 24.95 ≈ 24.9

The perimeter of the triangle ABC will be 24.9.

Then the correct option is C.

14-inch pizza

Step-by-step explanation:

The area of a circle (or a pizza) is πr^2, if r is the radius.

For a 14-inch pizza, the radius is 14/2=7 and therefore the area is π*7^2 which is approximately 154 square inches. Therefore, the price per square inch is 12/154, or approximately 0.078 dollars per inch.

Similarly, the area of a 4-inch pizza is π*2^2 which is approximately 12.5 square inches, two 4-inch pizzas are 25, and so the price per square inch is 8/25 which is approximately 0.32 dollars per inch.

So the 14-inch pizza is the better deal.
