Answer:

y=1/5(x+8)-9

Step-by-step explanation:

Point Slope Formula: y=m(x-x1)+y

y=1/5(x+8)-9

Answer:

[tex]y+9=\frac{1}{5} (x+8)[/tex]

Step-by-step explanation:

We are given that a line has a slope (m) of 1/5, and passes through the point (-8, -9).

We want to write the equation of this line in point-slope form.

Point-slope form is given as [tex]y-y_1=m(x-x_1)[/tex], where m is the slope and [tex](x_1,y_1)[/tex] is a point.

As we are given both the slope and the point, we can plug those values into the equation.

Starting with the slope, we can replace m with 1/5.

[tex]y-y_1=\frac{1}{5} (x-x_1)[/tex]

Now, substitute -8 as [tex]x_1[/tex] and -9 as [tex]y_1[/tex]. We get:

[tex]y--9=\frac{1}{5} (x--8)[/tex]

This can be simplified to:

[tex]y+9=\frac{1}{5} (x+8)[/tex]

Answer:

11 cm

Step-by-step explanation:

A = [tex]s^{2}[/tex]

Known that A = 121 [tex]cm^{2}[/tex],

121 [tex]cm^{2}[/tex] = [tex]s^{2}[/tex]

s = [tex]\sqrt{121}[/tex] cm = 11 cm

Done :)

The side length of a square launch pad is 11 centimeter.

Here,

Darius is building a square launch pad for a rocket project.

The area of the pad is 121 square centimeters.

We have to find, it's side length.

What is Area of square?

The area of a square = side x side

Since each side of a square is the same, it can simply be the length of one side squared.

Now,

The area of the pad is 121 square centimeters.

We use the area formula,

⇒[tex]A = s^{2}[/tex]

⇒ [tex]s^{2} = 121[/tex]

⇒[tex]s = \sqrt{121}[/tex]

⇒ [tex]s = 11[/tex]

Hence, The side length of a square launch pad is 11 centimeter.

Answer:

The answer is "12"

Step-by-step explanation:

Let f(x) be the function, where x specified in a certain section by the series of queries that have been addressed also as function.

Answer:

3886.53 [tex]m^{2}[/tex]

Step-by-step explanation:

The running track consist of two semicircles and a rectangle.

So that;

Diameter of the semicircles = width of the rectangle = 73 m

radius = [tex]\frac{diameter}{2}[/tex]

          = [tex]\frac{73}{2}[/tex]

          = 36.5 m

But the two semicircles form a circle, so that;

Circumference of a circle = 2[tex]\pi[/tex]r

Circumference of the circle formed by the semicircles = 2 x [tex]\frac{22}{7}[/tex] x 36.5

                                          = 229.43 m

Thus,

length of the running track = circumference of the circle formed + length of the two sides of the rectangle

                                             = 229.43 + 84.39 + 84.39

                                             = 398.21 m

The length of the running track is 398.21 m.

Therefore;

Area of the running track = length x width

                                         = 398.21 x 9.76

                                         = 3886.5296

The area of the running track is 3886.53 [tex]m^{2}[/tex].

Answer:

6p

Step-by-step explanation:

Putting a variable next to the coefficient is the same thing as multiplying. You always put the number before the letter.

Hope that helps and have a great day!

The product of p and 6 is written as 6p.

What is Multiplication?

To multiply means to add a number to itself a particular number of times. Multiplication can be viewed as a process of repeated addition.

Given that;

The expression as;

'The product of a number p and six'

Now, The multiplication of two number is written with sign ( × ).

Thus, The product of a number p and six is written as;

⇒ p × 6

⇒ 6p

Thus, The product of p and 6 is written as 6p.

Answer:

Step-by-step explanation:

12 x 15 = 180. 180 divided by 0.5 = 360. Thats the only answer I could get.

Given that the radius of the puddle expands, originally, at a rate of 1/4 unit/second instead of 1/2 unit/second.

The current rate of expension of the radius,

\frac {r(t)}{t}=frac 1 4 unit/second ...(i)

The resultant composite function is area, A(r(t)).

The area of a circular region having radius r is,

[tex]A(r)=\pi r^2[/tex]

If the radius is the function of time, then the composite function is

[tex]A(r(t))=\pi \(r(t))^2[/tex]

To determine the rate of change of area with respect to time, differentiate the composite function A(r(t)) once with respect to time, we have

[tex]\frac {d\{A(r(t))\}}{dt}=\pi \left(2\frac {d\{r(t)\}}{dt}\right)[/tex]

So, the composite function is changing twice of the rate of change of the radius.

By using equation (i), if r(i) is changing with R= 1/4 unit / second.

Then, A(r(t)) will change 2 x 1/4 = 1/2 square unit/second.

Answer:

3-16 is your answer

Answer:

280 adult tickets

130 student tickets

190 children tickets

were sold at the concert

Step-by-step explanation:

Let the number of students be s , adults a and children c

Total 600;

Thus;

a + s + c = 600 •••••••(i)

let us look at revenue

Revenue = number * ticket price

For adults; a * 7 = $7a

For students ; s * $3 = $3s

For children; c * $2 = $2c

Total is 3150

thus;

7a + 3s + 2c = 3150 ••••••••(ii)

150 more adults than students;

a = s + 150 ••••••(iii)

Substitute iii into ii and i

into ii

7(s + 150) + 3s + 2c = 3150

7s + 1050 + 3s + 2c = 3150

9c + 3s = 3150-1050

9c + 3s = 2,100 •••••••(x)

Substitute into i

a + s + c = 600

s + 150 + s + c = 600

2s + c = 600 - 150

2s + c = 450

c = 450 - 2s ••••••(xx)

Now substitute xx into x

9(450-2s) + 3s = 2100

= 4050-18s + 3s = 2100

4050-2100 = 18s - 3s

15s = 1950

s = 1950/15

s = 130

c = 450 -2s

c = 450 - 2(130)

c = 450 - 260

c = 190

a = 150 + s

a = 150 + 130

a = 280
