Answer:

Step-by-step explanation:

let the numbers be x and y,then

x+y=18

x=18-y

also xy=-63

(18-y)y=-63

18y-y²=-63

y²-18y-63=0

y²-21y+3y-63=0

y(y-21)+3(y-21)=0

(y-21)(y+3)=0

y=21,-3

when y=21

x=18-21=-3

when y=-3

x=18-(-3)=18+3=21

so numbers are -3 and 21.

Answer:

The sum of x and y is a rational number.

Step-by-step explanation:

Answer:

517.5 mi^2

Step-by-step explanation:

Divide shapes into 3 shapes ( 1 triangle and 2 rectangles

b = 17

h = 25

Area of triangle = [tex]\frac{1}{2}[/tex] Bh

A = [tex]\frac{1}{2}[/tex] (17)(25)

A = 212.5 mi^2

Area of 1st rectangle = lw = 17(9) = 153 mi^2

Area of 2nd rectangle = lw = 19(8) = 152 mi^2

Area of figure = 212.5 +153 + 152 = 517.5 mi^2

Answer:

36

Step-by-step explanation:

The numbers given represent an arithmetic series with a common difference of -5. The formula to find the nth term of an arithmetic sequence is:

a + (n - 1)d

where a is the first term and d is the common difference. We can substitute our values in:

261 + (46 - 1)(-5)

261 + (45)(-5)

261 + (-225)

Answer:

8

Step-by-step explanation:

12/1.5 is 8

you divide the total amount (12) by how much you're giving out (1.5 or 1 1/2) to find how many even groups can get a share

Answer:

See below

Step-by-step explanation:

Finding a:

[tex]\displaystyle sin (\theta) = \frac{opposite }{hypotenuse}[/tex]

Where θ = 45° , opposite = a, hyp = 4√2

[tex]\displaystyle sin (45)=\frac{a}{4\sqrt{2} } \\\\\frac{1}{\sqrt{2} } = \frac{a}{4\sqrt{2} } \\\\1 = \frac{a}{4} \\\\\boxed{a = 4}[/tex]

Finding c:

[tex]\displaystyle tan (\theta) = \frac{opposite }{adjacent}[/tex]

Where θ = 45°, opposite = 4, adjacent = c

tan 45 = 4 / c

1 = 4 / c

Multiply both sides by c

c = 4

Finding b:

[tex]\displaystyle sin(\theta) = \frac{opposite}{hypotenuse}[/tex]

Where θ = 30°, opposite = a(4), hypotenuse = b

sin 30 = 4 / b

[tex]\displaystyle \frac{1}{2} = \frac{4}{b}[/tex]

Cross Multiply

1 * b = 4 * 2

b = 8

Finding d:

[tex]\displaystyle tan (\theta) = \frac{opposite }{adjacent}[/tex]

Where θ = 30°, opposite = a(4) , adjacent = d

tan 30 = 4 / d

[tex]\displaystyle \frac{1}{\sqrt{3} } = \frac{4}{d} \\\\[/tex]

Cross Multiplying

1 * d = 4√3

[tex]\boxed{d = 4\sqrt{3}}[/tex]

Answer:

x ≈ 11.09

Step-by-step explanation:

Using the rule of logarithms

[tex]log_{b}[/tex] x = n ⇒ x = [tex]b^{n}[/tex]

Given

ln(x + 9) = 3 , that is

[tex]log_{e}[/tex] (x + 9) = 3 , then

x + 9 = e³ ( subtract 9 from both sides )

x = e³ - 9 ≈ 11.09 ( to the nearest hundredth )

Answer:

B

Step-by-step explanation:

-x - 1 = x^2 + x

x^2 + 2x + 1 = 0

(x+1)(x+1) = 0

x = -1 (double soution)

y = 1-1 =

y =0

(-1,0) = double solution

Answer:

  B.  7.85

Step-by-step explanation:

Your knowledge of the triangle inequality tells you 'b' cannot be greater than 11+14 = 25, eliminating choices A and C. If 'b' were 24.05, as suggested by choice D, the angle at B would be nearly a straight angle.

So, the only viable choice is b = 7.85.

__

Your knowledge of "special" triangles tells you that if B were 30°, then b would be 14/2 = 7.0. The angle is slightly larger than that, so the side opposite is slightly larger than 7.0.

__

In this geometry, the Law of Cosines would be used to find b. That relationship tells you ...

  b = √(a^2 +c^2 -2ac·cos(B))

  b = √(121 +196 -308·cos(34°)) ≈ √61.66 ≈ 7.85

About special triangles

There are two "special" right triangles whose trig functions are not difficult to remember. They appear quite often in algebra, geometry, and trig problems, so remembering their properties can be useful.

A 30°-60°-90° right triangle has side lengths in the ratios 1 : √3 : 2. The shortest side is exactly half the length of the hypotenuse. This fact is what we referred to above.

A 45°-45°-90° isosceles right triangle has side lengths in the ratios 1 : 1 : √2. This is the triangle you get by drawing a diagonal in a square. These ratios tell you the diagonal of a square is always √2 times the side length.
