Answer:

x = 9.7    y = 11.4

Step-by-step explanation:

tan 45 = x/6

x = tan 45 (6)

= 9.7

c² = a² + b²

c² = 9.7² + 6²

= 94.09 + 36

= 130.09

= 11.4

Answer:

volume = 684π m³ or 2148.85 m³

Answer:

Measure of segment JL is 20 cm.

Step-by-step explanation:

By applying geometric mean theorem in the given right triangle,

[tex]\frac{JM}{KM}=\frac{KM}{ML}[/tex]

[tex](KM)^2=(LM)(ML)[/tex]

[tex]8^2=(JM)(4)[/tex]

[tex]JM=\frac{64}{4}[/tex]

[tex]JM=16[/tex]

Since, [tex]JL=JM+ML[/tex] [By segment addition postulate]

[tex]JL=16+4[/tex]

[tex]JL=20[/tex] cm

Therefore, measure of segment JL is 20 cm.

The Interquartile range for the given data is 4.

The interquartile range is a measure of where the “middle fifty” is in a data set. Where a range is a measure of where the beginning and end are in a set, an interquartile range is a measure of where the bulk of the values lie.

Here,

Given data: 23, 24, 25, 27, 27, 28, 29, 30, 30, 31, 32, 37

First Quartile Q₁ = (n-1)/4 th term

                      Q₁ = (12-1)/4 th term

                      Q₁ = 11/4 th term

                      Q₁ = 2.75 th term

                      Q₁ = 26

Third Quartile Q₃ = 3(n-1)/4 th term

                        Q₃ = 3 X 11 / 4

                        Q₃ = 8.25th term

                        Q₃ = 8th term + 0.25 (9th term - 8th term)

                        Q₃ = 30 + 0.25 (30 -30 )

                        Q₃ = 30 + 0

                         Q₃ = 30

Interquartile range = (Q₃ - Q₁ ) = (30 - 26)

                                 = 4

Thus, the interquartile range = 4.

Answer:

m<UKJ = 80

Step-by-step explanation:

These angles are equal to each other because they're corresponding angles:

12x - 4 = 10x + 10

12x - 10x = 10 + 4

2x = 14

x = 7

m<UKJ:

12x - 4

12(7) - 4

Answer:

Please find attached the required graph of the equation, y = x² - 2·x - 8, created using MS Excel

Step-by-step explanation:

The given function required to be plot is y = x² - 2·x - 8

Therefore, the coordinates of the vertex of the parabola formed by the equation (h, k) is given as follows;

h = -(-2)/(2×1) = 1

k = 1² - 2×1 - 8 = -9

The coordinates of the vertex = (1, -9)

The roots of the equation is given when y = 0, as follows;

At the roots, we have;

x² - 2·x - 8 = 0

By factorizing, we get

x² - 2·x - 8 = (x - 4)·(x + 2) = 0

Therefore. the roots of the equation are;

x = 4, and x = -2

The coordinates of the roots are;

(4, 0), and (-2, 0)

Two other points can be found at when x = 3 and when x = 0 as follows;

When x = 3, we have;

y = 3² - 2×3 - 8 = -5

(3, -5)

When x  = 0, we have;

y = 0² - 2×0 - 8 = -8

(0, -8)

The five points are;

(1, -9), (4, 0), (-2, 0), (3, -5), (0, -8)

The graph of the equation created using MS Excel showing the five points is attached.

Answer:

468 in ^2; a

Step-by-step explanation:

Add each side of the prism;

Base: 15*10 = 150

Rectangular sides: 10*12+9*10 = 210

Triangular sides (x2): ((9*12)/2)*2 = 108

108+210+150 = 468 in ^2
