Answer:

True

Step-by-step explanation:

The formula for the area of a circle is πr² where r is the radius. So if 3 is the radius, plug it into the formula:

π(3²)

Simplify it:

π(9)

This can be rewritten as:

9π

So, the answer is true

Hope this helps! :)

Answer:

children= 245

adults= 274

Step-by-step explanation:

Step one:

let the number of children be x

and adults be y

So

1.75x+2.25y=1045.25------------1

and

x+y=519---------------2

the systems of the equation for the situation is

1.75x+2.25y=1045.25------------1

x+y=519---------------2

from 2, x= 519-y

put x= 519-y in 1

1.75(519-y)+2.25y=1045.25

908.25-1.75y+2.25y=1045.25

collect like terms

1.75y+2.25y=1045.25-908.25

0.5y=137

divide by 0.5

y=137/0.5

y=274

put y= 274 in 1

x+274=519

x=519-274

x=245

Answer: Profit of $3,750

Step-by-step explanation:

Sold half of the sets at a profit of 25%;

= (15,000 * 5 sets) * 25%

= $‭18,750‬

Sold the other half at a loss of 20%;

= (15,000 * 5) * 20%

= $15,000

Profit (loss) = 18,750 - 15,000

= $3,750

Hello!

[tex]\large\boxed{f^{-1} = \frac{5x+2}{4x-2}, f^{-1}(3) = \frac{17}{10} }[/tex]

[tex]f(x) = \frac{2x +2}{4x - 5}[/tex]

Find the inverse by swapping the x and y variables:

[tex]y = \frac{2x +2}{4x - 5}\\\\x = \frac{2y +2}{4y - 5}[/tex]

Begin simplifying. Multiply both sides by 4y - 5:

[tex]x(4y - 5) = 2y + 2[/tex]

Start isolating for y by subtracting 2 from both sides:

[tex]x(4y - 5) -2 = 2y[/tex]

Distribute x:

[tex]4yx - 5x - 2 = 2y[/tex]

Move the term involving y (4yx) over to the other side:

[tex]- 5x - 2 = 2y - 4yx\\\\[/tex]

Factor out y and divide:

[tex]- 5x - 2 = y(2 - 4x)\\\\y = \frac{-5x-2}{-4x+2} \\\\y = \frac{-(5x + 2)}{-(4x - 2)} \\\\y^{-1} = \frac{5x + 2}{4x - 2}[/tex]

Use this equation to evaluate [tex]f^{-1}(3)[/tex]

[tex]f^{-1}(3) = \frac{5(3) + 2}{4(3) - 2} = \frac{17}{10}[/tex]

Answer:

m=-1/4

Step-by-step explanation:

Perpendicular lines are negative reciprocals.

So if you have a slope of m= 4x you can break it up into, two parts

                         m= -4x

this is the negative^

and the reciprocal of m= -4x is m= -1/4x

The slope of the green line if the lines are perpendicular would be -1/4.

If two lines are perpendicular to each other, then their slopes are negative reciprocal of each other.

That means, if one line's slope is 'a', then its perpendicular line's slope would be -1/a.

Slope of parallel lines are same. Slopes of perpendicular lines are negative reciprocal of each other.

For the two lines two be perpendicular, the product of their slope must be -1.

Let the slope of the red and green line be m1 and m2.

Given the following

The Slope of red line = 4

According the definition, we get,

4m2 = -1

m2 = -1/4

Hence, the slope of the green line if the lines are perpendicular is -1/4

Not so sure about the answer, but hopefully it helps.

Given:

The equation is

[tex]y=-1(x-4.5)^2+15.25[/tex]

To find:

The standard form of the given equation.

Solution:

We have,

[tex]y=-1(x-4.5)^2+15.25[/tex]

It is a quadratic equation.

The standard form of a quadratic equation is [tex]y=ax^2+bx+c[/tex]. So, we need to write the given equation in this form.

[tex]y=-(x-4.5)^2+15.25[/tex]

[tex]y=-[x^2-2(x)(4.5)+(-4.5)^2]+15.25[/tex]         [tex][\because (a-b)^2=a^2-2ab+b^2][/tex]

[tex]y=-[x^2-9x+20.25]+15.25[/tex]

[tex]y=-x^2+9x-20.25+15.25[/tex]

[tex]y=-x^2+9x-5[/tex]

Therefore, the required equation in standard form is [tex]y=-x^2+9x-5[/tex].
