The length of AB is 25.6 mi.
Step-by-step explanation:
You have to apply Sine Rule :
[tex] \frac{AB}{ \sin(90) } = \frac{22.6}{ \sin(62) } [/tex]
[tex]AB = \frac{22.6}{ \sin(62) } \times \sin(90) [/tex]

The vertices of are F(2,1), G(4,1), and H(4,-1). The vertices of the image of the triangle after a dilation centered at (0,0) are F'(4,2), G'(8,2), and H'(8,-2). What is the scale factor of the dilation?
Answer:
The scale factor of the dilation is 2
Step-by-step explanation:
The given vertices the ΔFGH are;
F(2, 1), G(4, 1), and H(4, -1)
The lengths of the sides of the triangle ΔFGH are;
The length of segment FG = √((4 - 2)² + (1 - 1)²) = 2
The length of segment FH = √((4 - 2)² + ((-1) - 1)²) = 2·√2
The length of segment GH = √((4 - 4)² + ((-1) - 1)²) = 2
After a dilation with the center of dilation = (0, 0), to give the ΔF'G'H', we have;
The given vertices the ΔF'G'H' are F'(4, 2), G'(8, 2), H'(8, -2)
The length of segment F'G' = √((8 - 4)² + (2 - 2)²) = 4
The length of segment F'H' = √((8 - 4)² + ((-2) - 2)²) = 4·√2
The length of segment G'H' = √((8 - 8)² + ((-2) - 2)²) = 4
The length of the sides of ΔFGH = 1/2 × The length of the sides of ΔF'G'H' or the length of the sides of ΔF'G'H' = 2 × The length of the sides of ΔFGH
Therefore, the scale factor of the dilation is 2.
what is the length, in centimeters, of EF
Answer:
8
Step-by-step explanation:
1. Use the Pythagorean theorem: a^2+b^2=c^2.
You are already given c (which is always the longest side of the triangle) and one of the legs, which can be either a or b.
2. Put the numbers into the equation and square them.
6^2+b^2=10^2
When you square the numbers, it becomes 36 + b^2 = 100.
3. Subtract 36 from both sides and take the square root of the difference.
b^2 = 64
[tex]\sqrt{64}[/tex] = 8
Answer: 8cm
Step-by-step explanation: Let’s use the Pythagorean Theorem! 6^2+x^2=10^2
36+x^2=100
x^2=64
X=8

what is the formula for 1, -3, 9, -27?
arithmetic or geometric?
Answer:
The formula of the geometric sequence is a[tex]_{n}[/tex] = [tex](-3)^{n-1}[/tex]
Step-by-step explanation:
The terms of the sequence are 1, -3, 9, -27
∵ -3 ÷ 1 = -3
∵ 9 ÷ -3 = -3
∵ -27 ÷ 9 = -3
∴ There is a common ratio between each two consecutive terms
∴ The sequence is geometric
∵ The formula of the geometric sequence is a[tex]_{n}[/tex] = a [tex]r^{n-1}[/tex], where
a is the first term r is the common ratio∵ The first term is 1
∴ a = 1
∵ The common ratio is -3
∴ r = -3
→ Substitute them in the formula above
∵ a[tex]_{n}[/tex] = (1) [tex](-3)^{n-1}[/tex]
∴ a[tex]_{n}[/tex] = [tex](-3)^{n-1}[/tex]
∴ The formula of the geometric sequence is a[tex]_{n}[/tex] = [tex](-3)^{n-1}[/tex]

15 – 5(4c – 7) = 50 pls solve C
Answer:
c = 0
Step-by-step explanation:
15 – 5(4c – 7) = 50
Expand.
15 - 20c + 35 = 50
Isolate 20c.
-20c = 50-15-35
Evaluate.
-20c = 0
Remove the negative sign.
-20c × (-1) = 0 × (-1)
Two negatives make a positive. Anything multiplied by 0 becomes 0.
20c = 0
Find c.
c = 0 ÷ 20
Evaluate.
c = 0
c = 7/4 is the solution to the equation 15 - 5(4c - 7)
Let's solve the equation step by step:
15 - 5(4c - 7) = 50
First, distribute the -5 to the terms inside the parentheses:
15 - 20c + 35 = 50
Combine like terms:
50 - 20c + 35 = 50
Combine the constant terms:
-20c + 85 = 50
Next, isolate the term with c by subtracting 85 from both sides of the equation:
-20c = 50 - 85
Simplify:
-20c = -35
Finally, divide both sides by -20 to solve for c:
c = (-35) / (-20)
Simplifying the division:
c = 7/4
Therefore, the solution to the equation 15 - 5(4c - 7) = 50 is c = 7/4.

In a music competition, a participant has to score a total of 40 points in the first four rounds combined to move on to the 5th and final round. Glen scored 4 points in the first round. He then went on to score additional points in the second, third and forth rounds. In each round he scored the identical points. Which inequality shows the number of points Glen scored.
Answer:
x ≥ 12
Step-by-step explanation:
Given that :
Total points required = 40
1st round point = 4
2nd, 3rd and 4th round points are identical
Let the point number of points = x
2nd + 3rd + 4th = 3
1st round + 3(x) ≥ 40
4 + 3x ≥ 40
3x ≥ 40 - 4
3x ≥ 36
x ≥ 12

What is a quadratic function?A polynomial function with one or more variables, where the largest exponent of the variable is two, is referred to as a quadratic function. In other terms, a "polynomial function of degree 2" is a quadratic function.
We can start by completing the square of the quadratic function g(k) = -k² + 6k - 9:
g(k) = -(k² - 6k + 9 ) = -(k - 3)²
Option A can be simplified as:
g(k) = -(k - 3)²
Compared with the completed square form of g(k), we can see that option A is equivalent to g(k).
Therefore, the answer is A. g(k) = -(k - 3)²

Answer:
A, C
Step-by-step explanation:
The domain is the list of x-values in the table. Choice A correctly lists the domain values.
The range is the list of y-values in the table. Choice B incorrectly describes the domain.
For x = -1, the table tells you f(x) = 6, so f(-1) = 6.
For x = 5, the table tells you f(x) = 12, so f(5) = 12, not -2.
Choices A and C are correct.
