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.

Please help 25p- it’s urgent
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:
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.

The ratio of blue skittles to red skittles in Tayler's bag is 3 to 4. If there are 20 red
skittles in Tayler's bag, how many total skittles does Tayler have? *
HELPPP ASAPPP PLEASE
Answer:
Tayler has 35 SHKITTLES IN ALL
Step-by-step explanation:
Since Tayler has 20 red Skittles, and the ratio of blue skittles to red skittles is 3 to 4, that means that Tayler has 3/4 as many blue skittles as she does red skittles. 3/4 of 20 is 15
20 + 15 = 35
Thus, Tayler has 35 skittles
SHKITTLES lol
number multiplied by a fraction is not always smaller than the original number. Explain this and give at least two examples to support your thinking.
Answer:
Sometimes, fractions can be written in 'improper' form, meaning that the top number (numerator) is bigger than the bottom number (denominator). So anything multiplied by a fraction like this will give a bigger number.
For example:
5 × 2/1 = 10
10 x 10/1 = 100
Step-by-step explanation:
Answer:
Step-by-step explanation:
There are two cases where this is true. When the fraction has the same numerator and denominator, or when the numerator is much larger than the denominator.
[tex]2*\frac{4}{4}=2[/tex]
[tex]2*\frac{100}{2}=100[/tex]
What is the area, in square meters, of the figure below?
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 :
Base of triangle, b = 2.2 mHeight of triangle, h = 0.5 mNow, 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.

While parasailing. Ryan spots a dolphin on the water below. If Ryan is 228 feet above the
water and the angle of depression to the dolphin is 15, what is the horizontal distance
between Ryan and the dolphin?
Answer:
850.9 feet
Step-by-step explanation:
The horizontal distance between Ryan and the dolphin is 850.907 feet.
What is Trigonometry?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

The function g(t) = -16t2 + vt + h represents the height of an object, g, in feet above the ground in relation to the time, t, in seconds, since the object was thrown into the air with an initial velocity of v feet per second at an initial height of h feet.
A model rocket is launched off the ground at an initial velocity of 80 feet per second.
What domain makes sense for the function in this context?
A. all positive numbers
B. 0 ≤ t ≤ 5
C. all real numbers
D. 0 ≤ t ≤ 100
Answer:
B. 0 ≤ t ≤ 5Step-by-step explanation:
The function is g(t) = -16t² + vt + h
At h = 0 and v = 80 we get the function:
g(t) = -16t² + 80tWe know g(t) can't be negative, then:
-16t² + 80t ≥0t² - 5t ≤ 0t(t - 5) ≤ 5t ≥0 and t ≤ 5, or0 ≤ t ≤ 5Correct option is B
