Answer:

27 attendees

Step-by-step explanation:

First, we can find the cost per attendee.

78÷26

3

So $3 per attendee.

Then divide 81 by 3 to find the number of possible attendees.

81÷3=27

Answer:

0 is the whole number

Step-by-step explanation:

negative numbers are negative so they can't be counted as whole numbers which means -5 isn't an option.

Whole numbers can't be stated in fraction form so 2/3 is not applicable here.

32.8 is also not the answer as decimals are part of a whole number, not actual whole numbers.

so, 0, is the only right answer here

Since this is a right triangle, we can use one of the three main trigonometric functions: sine, cosine, or tangent.

Remember: SOH-CAH-TOA

Looking from the angle, we know the opposite side and the hypotenuse. Therefore, we should use the sine function.

sin(x) = 21/40

x = sin^-1(21/40)

x = 32 degrees

Answer:

  b = -2ax

Step-by-step explanation:

Multiply both sides of the equation by -2a.

  x = -b/(2a)

  (-2a)x = b(-2a)/(-2a) = b

  b = -2ax

Answer:

90°

Step-by-step explanation:

Rotation counterclockwise means the rotating an object over a fixed point in the opposite direction of our normal wall clock.

To get exact position of shoe B, shoe A would be rotated in about 90° in the opposite direction of a clock.

Thus, shoe A was rotated 90° about a fixed point to create shoe B.

The axis of symmetry always passes through the vertex of the parabola . The x -coordinate of the vertex is the equation of the axis of symmetry of the parabola. For a quadratic function in standard form, y=ax2+bx+c , the axis of symmetry is a vertical line x=−b2a .

Answer:

NO

Step-by-step explanation:

To find the length of AB

AB = sqrt( (x2-x1)^2 + (y2-y1)^2)

      = sqrt ( ( 2 - -1)^2+ ( -1 -3)^2)

      = sqrt( 3^2 + (-4)^2)

      = sqrt(9+16)

    = sqrt(25)

    = 5

To find the length of AC

AC = sqrt( (x2-x1)^2 + (y2-y1)^2)

      = sqrt ( ( -4 - -1)^2+ ( -1 -3)^2)

      = sqrt( ( -3)^2 + (-4)^2)

      = sqrt(9+16)

    = sqrt(25)

    = 5

To find the length of BC

BC = sqrt( (x2-x1)^2 + (y2-y1)^2)

      = sqrt ( ( -4-2)^2+ ( -1 --1)^2)

      = sqrt( ( -6)^2 + (0)^2)

      = sqrt(36)

    = 6

    This is not an equilateral triangle since BC is not equal to AB = AC

Answer:

Step-by-step explanation:

Some coordinates of a triangle is given to us. And we need to find the length of AB , BC and AC . The given coordinates are ,

[tex]\rm\implies Coordinates = A(-1,3) , B(2,-1) \ and \ C(-4,-1) [/tex]

We can use the Distance Formula to find the length of sides of the triangle .

Finding length of AB :-

[tex]\rm\implies Distance =\sqrt{ ( x_2-x_1)^2+(y_2-y_1)^2} \\\\\rm\implies \overline{AB}= \sqrt{ (-1-2)^2+(-1-3)^2} \\\\\rm\implies \overline{AB}= \sqrt{ (-3)^2+(-4)^2} \\\\\rm\implies \overline{AB}= \sqrt{ 9 + 16} \\\\\rm\implies \overline{AB}= \sqrt{25} \\\\\rm\implies\boxed{\red{\rm \overline{AB}= 5 \ units}}[/tex]

Finding length of AC :-

[tex]\rm\implies Distance =\sqrt{ ( x_2-x_1)^2+(y_2-y_1)^2} \\\\\rm\implies \overline{AC}= \sqrt{ (-1+4)^2+(-1-3)^2 }\\\\\rm\implies \overline{AC}= \sqrt{ (-3)^2+(-4)^2} \\\\\rm\implies \overline{AC}= \sqrt{ 9 + 16} \\\\\rm\implies \overline{AC}= \sqrt{25} \\\\\rm\implies\boxed{\red{\rm \overline{AC}= 5 \ units}}[/tex]

Finding length of BC :-

[tex]\rm\implies Distance =\sqrt{ ( x_2-x_1)^2+(y_2-y_1)^2} \\\\\rm\implies \overline{BC}= \sqrt{ (-4-2)^2+(-1-1)^2} \\\\\rm\implies \overline{BC}= \sqrt{ 6^2+0^2} \\\\\rm\implies \overline{BC}= \sqrt{ 36+0} \\\\\rm\implies \overline{BC}= \sqrt{36} \\\\\rm\implies\boxed{\red{\rm \overline{BC}= 6 \ units}}[/tex]

Is it a Equilateral triangle ?

No the given triangle is not a equilateral triangle since the measure of all sides is not same.

Answer:

[tex]\frac{3x}{4x} =\frac{3x+7}{5x-8}[/tex]

[tex]\frac{3}{4} =\frac{3x+7}{5x-8}\: (cross\: multiply)[/tex]

[tex]3(5x-8)=4(3x+7)[/tex]

[tex]15x-24=12x+28\\+24~~~~~~~~~~~~+24[/tex]

[tex]15x=12x+52\\-12x~~~~-12x\\-------\\3x=52[/tex]

[tex]\frac{3x}{3} =\frac{52}{3}[/tex]

[tex]x=52/3[/tex]

Answer:

  4 days

Step-by-step explanation:

The total charges can be modeled by ...

  c = 75d + 75 . . . . . . charges for d days

Filling in the given charge, we find ...

  375 = 75d +75

  300 = 75d . . . . . . . subtract 75

  4 = d . . . . . . . . . . divide by 75

Chris rented the car for 4 days.

Answer:

4 DAYS!! THIS GETS ALL 3 MARKS!!!

Step-by-step explanation:

Chris rents a car for a total of £375. The rental charges are £150 for the first day and £75 per day after that. For how many days did Chris rent the car? You must show your working.

£375.00 - £150.00 = £225.00

£225.00 - £75.00 = £150.00

£150.00 - £75.00 = £75.00

£75.00 - £75.00 = £00.00

= Chris rented the car for 4 days

225.00 ÷ 75 = 3

3 days + 1 days = 4 days

he total charges can be modeled by ...

c = 75d + 75 . . . . . . charges for d days

Filling in the given charge, we find ...

375 = 75d +75

300 = 75d . . . . . . . subtract 75

4 = d . . . . . . . . . . divide by 75

Answer:4 days

Total=375

150+(75×4)=150+75+75+75=375

4 days

Answer:

the second option, y=1/2cos(x- pi/4)

Step-by-step explanation:

After answering the question provided, we can predict that the result will be as  The position and direction of the relevant parabola will determine the appropriate response.

A mathematical equation is a process that links two statements and indicates equality using the equals sign (=). A mathematical statement that proves the equality of two mathematical expressions is known as an equation in algebra. For instance, the equal sign separates the numbers 3x + 5 and 14 in the equation 3x + 5 = 14. A mathematical formula may be used to understand the link between the two sentences that are written on opposite sides of a letter. Frequently, the logo and the particular software are identical. like in 2x - 4 = 2, for example.

It is hard to tell which equation may be the equation of the parabola without further details on the parabola's orientation and location.

The equations in options A and B are parabolas with upward or downward openings and a vertex at the origin. The equation of a parabola with its vertex at the origin and an opening to the right or left is in Option C. The equation of a parabola with an upwards or downwards opening and its vertex at the point is in Option D. (0,0).

The position and direction of the relevant parabola will determine the appropriate response.

Answer:

The absolute value equation is |x| =[tex]\frac{1}{2}[/tex]

Step-by-step explanation:

The standard form of absolute value equation is |x-a| =b

Where 'b' is distance from midpoint to one of the end point.

'a' is midpoint.

Here we need to write absolute value equation for the solution -[tex]\frac{1}{2}[/tex] to [tex]\frac{1}{2}[/tex]  .

The midpoint of -[tex]\frac{1}{2}[/tex]  to [tex]\frac{1}{2}[/tex]  is 0. Because [tex]\frac{\frac{-1}{2} +\frac{1}{2} }{2} =0[/tex]

The distance from 0 to [tex]\frac{1}{2}[/tex]  is [tex]\frac{1}{2}[/tex]

The absolute value equation is

|x-0 | =[tex]\frac{1}{2}[/tex]

We can simplify it as

|x| =[tex]\frac{1}{2}[/tex]

x = -7/b

Step-by-step explanation:

bx = -7

Divide each side by b

bx/b = -7/b

x =-7/b

Solve the equation for x : bx = -7

Here we are provided to find for x so from the equation by cross multiplying we will remove b to the right hand side of the equation and then we can get x

bx = -7

Now, to cross multiply

x = -7/b

Therefore, the required answer is -7/b
