Answer:

17= Prime number

54= Composite

77=Composite

23=Prime

Hello there!

Prime numbers have 2 factors and composite numbers have 3 or more factors.

17 is prime because it has only 2 factors: 1 and itself.

54 is composite because it has more than 3 factors.

77 is composite because it has more than 3 factors.

23 is prime because it has only 2 factors.

Answer:

p = 20, q = 20, r = 30

Step-by-step explanation:

The triangle to the left of OA is isosceles ( 2 equal radii ), then the base angles are congruent, so

p = 20

The 3 angles in this triangle sum to 180°, then the angle at O is

180 - (20 + 20) = 180 - 40 = 140°

AB is a straight line so angle in triangle containing q is 180 - 140 = 40

The triangle containing q is also isosceles ( 2 equal radii ) then base angles are congruent, then

q = [tex]\frac{180-140}{2}[/tex] = [tex]\frac{40}{2}[/tex] = 20

The triangle to the right of OA is also isosceles ( 2 equal radii ) then the base angles are congruent, so

r = 30

Then p = 20, q = 20, r = 30

Answer:

[tex]x = 1 + \sqrt{2} \ \ or \ 1- \sqrt{2}[/tex]

Step-by-step explanation:

Given;

x² - 2x - 1 = 0

Solve by completing the square method;

⇒ take the constant to the right hand side of the equation.

x² - 2x = 1

⇒ take half of coefficient of x = ¹/₂ x -2 = -1

⇒ square half of coefficient of x and add it to the both sides of the equation

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

[tex](x-1)^2 = 1 + 1\\\\(x-1)^2 = 2\\\\[/tex]

⇒ take the square root of both sides;

[tex]x-1 = +/- \ \ \sqrt{2} \\\\x = 1 + \sqrt{2} \ \ or \ 1- \sqrt{2}[/tex]

Therefore, option B is the right solution.

Answer:

(4w^2+180w+1800) meters^2

Explanation:

(60+2w) x (30+2w)

1800+120w+4w^2+60w

Combine like terms and rearrange into quadratic equation

4w^2+180w+1800

Answer:

850.9 feet

Step-by-step explanation:

The horizontal distance between Ryan and the dolphin is 850.907 feet.

One area of mathematics known as trigonometry examines the relationship between the sides and angles of a right triangle. The relationship between sides and angles is defined for 6 trigonometric functions.

We have,

Ryan is 228 feet above the water and the angle of depression to the dolphin is 15.

Using trigonometry

tan 15 = 228/ x

x= 228/ tan 15

x= 228 / 0.26794919243

x = 850.907  feet

Answer:

[tex]0.55[/tex] square meters

Step-by-step explanation:

The area of a triangle can be calculated by multiplying its height and base, then dividing the result by [tex]2[/tex]. As an algebraic expression, that would be [tex]\frac{bh}{2}[/tex], where [tex]b[/tex] is the base and [tex]h[/tex] is the height. In this case, [tex]b=2.2[/tex] and [tex]h=0.5[/tex]. Therefore, the area of the triangle is:

[tex]\frac{bh}{2}\\= \frac{2.2*0.5}{2}\\=\frac{1.1}{2} \\= 0.55[/tex]

Hope this helps!

By observing the diagram, we have :

Now, we know that :

[tex] \large \underline{\boxed{\tt{Area_{(triangle)} = \dfrac{1}{2} \times base \times height}}}[/tex]

So, by substituting values, Area of given triangle will be :

[tex] \sf : \implies Area = \dfrac{1}{2} \times 2.2\: m \times 0.5\: m[/tex]

[tex] \sf : \implies Area = \dfrac{1}{\cancel{2}} \times \dfrac{\cancel{22}}{10} \: m \times \dfrac{5}{10} \: m[/tex]

[tex] \sf : \implies Area = 1 \times \dfrac{11}{10} \: m \times \dfrac{5}{10}\: m[/tex]

[tex] \sf : \implies Area = \dfrac{55}{100} \: m^{2}[/tex]

[tex] \sf : \implies Area = 0.55 \: m^{2}[/tex]

Hence, Area of given triangle is 0.55 m².
