Answer:

[tex]B =(3.3,1.7)[/tex]

Step-by-step explanation:

Given

[tex]A(x_1,y_1) = (-4,-2)[/tex]

[tex]P(x,y) = (2,1)[/tex]

[tex]m : n = 9 : 2[/tex]

Required

The coordinates of [tex]B(x_2,y_2)[/tex]

The line segment from ratio is calculated as:

[tex](x,y) = (\frac{mx_2 + nx_1}{m+n},\frac{my_2 + ny_1}{m+n})[/tex]

Substitute: A, P, m and n

[tex](2,1) = (\frac{9 * x_2 + 2*-4}{9+2},\frac{9*y_2 +2 *-2}{9+2})[/tex]

[tex](2,1) = (\frac{9x_2 -8}{11},\frac{9y_2 -4}{11})[/tex]

Multiply through by 11

[tex](22,11) = (9x_2 -8,9y_2 -4)[/tex]

By comparison:

[tex]9x_2 - 8 = 22[/tex]

[tex]9y_2 - 4 = 11[/tex]

So, we have:

[tex]9x_2 - 8 = 22[/tex]

[tex]9x_2 = 22 +8[/tex]

[tex]9x_2 = 30[/tex]

Solve for x2

[tex]x_2 = 30/9[/tex]

[tex]x_2 = 3.3[/tex]

[tex]9y_2 - 4 = 11[/tex]

[tex]9y_2 = 11+4[/tex]

[tex]9y_2 = 15[/tex]

Solve for y2

[tex]y_2 =15/9[/tex]

[tex]y_2 =1.7[/tex]

So, the coordinates of B is:

[tex]B =(3.3,1.7)[/tex]

w + 124 = 180

w = 180 - 124

w = 56

Answer:

1) Area:

So to find area follow the formula

a=πr^2

a=area

π= pi or 3.14 in this situation

r= radius

So we have only the diameter.

To in Find the radius you can divide the diameter by 2 and get the radius which is

84/2=42

3.14*42^2=

Area: 5538.96 ft^2

2) Circumference:

To find the circumfeence you just multiply the diameter by π or in this case 3.14.

c=πd

c= circumference  

d= diameters

3.14*84=

Circumfrence: 263.76 ft

Hello! answer: 68

Step-by-step explanation:

x = 19 19 × 4 = 76 76 + 36 = 112

19 × 6 = 114 114 - 2 = 112

112 + 112 = 224 360 - 224 = 136 136 ÷ 2 = 68 therefore the answer is 68

Answer:

1508

Step-by-step explanation:

Answer:

Below in bold.

Step-by-step explanation:

Part A.

9a^2 - 24a + 16

= (3a - 4)(3a - 4).

Length of each side = 3a - 4 units.

Part B.

25a^2 − 36b^2

= (5a - 6b)(5a + 6b).

The dimensions are 5a-6b and 5a+6b.

The length of each side would be 3a - 4 units. The dimensions are 5a - 6b and 5a + 6b.

The area of the rectangle is the product of the length and width of a given rectangle.

The area of the rectangle = length × Width

Part A.

The area of a square is [tex]9a^2 - 24a + 16[/tex] square units.

To determine the length of each side of the square by factoring the area expression completely.

[tex]9a^2 - 24a + 16\\\\= (3a - 4)(3a - 4).[/tex]

The Length of each side = 3a - 4 units.

Part B.

The area of a rectangle is [tex]25a^2 - 36b^2[/tex]square units.

To determine the dimensions of the rectangle by factoring the area expression completely.

[tex]25a^2 - 36b^2\\= (5a - 6b)(5a + 6b).[/tex]

The dimensions are 5a - 6b and 5a + 6b.

Hope that helps!

Answer:

G. 60 m²

Step-by-step explanation:

The lawn is in the shape of a trapezium.

The area of a trapezium can be found using the equation  0.5*h*(a+b), where h is the height and a and b are the top and bottom of the shape.

Area = 0.5*h*(a+b)

= 0.5*4*(12+18)

Using the normal distribution, we have that:

a) 34.13% of pizzas were prepared and delivered between 20 and 25 minutes.

b) 34.46% of pizzas were prepared and delivered in less than 18 minutes.

c) 2.28% of the pizza will be free.

The z-score of a measure X of a normally distributed variable with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex] is given by:

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

The mean and the standard deviation are given, respectively, by:

[tex]\mu = 20, \sigma = 5[/tex]

For item a, the probability is the p-value of Z when X = 25 subtracted by the p-value of Z when X = 20, hence:

X = 25:

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

[tex]Z = \frac{25 - 20}{5}[/tex]

Z = 1

Z = 1 has a p-value of 0.8413.

X = 20:

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

[tex]Z = \frac{20 - 20}{5}[/tex]

Z = 0

Z = 0 has a p-value of 0.5.

0.8413 - 0.5 = 0.3413.

Hence 34.13% of pizzas were prepared and delivered between 20 and 25 minutes.

For item b, the probability is the p-value of Z when X = 18, hence:

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

[tex]Z = \frac{18 - 20}{5}[/tex]

Z = -0.4

Z = -0.4 has a p-value of 0.3446.

34.46% of pizzas were prepared and delivered in less than 18 minutes.

For item c, the proportion is one subtracted by the p-value of Z when X = 30, hence:

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

[tex]Z = \frac{30 - 20}{5}[/tex]

Z = 2

Z = 2 has a p-value of 0.9772.

1 - 0.9772 = 0.0228, hence 2.28% of the pizza will be free.
