m=change in ychange in x
The change in x
is equal to the difference in x-coordinates (also called run), and the change in y
is equal to the difference in y-coordinates (also called rise).

Two 50-μm-wide slits spaced 0.25 mm apart are illuminated by blue laser light with a wavelength of 450 nm. The interference pattern is observed on a screen 2.0 m behind the slits.
How many bright fringes are seen in the central maximum that spans the distance between the first missing order on one side and the first missing order on the other side?
Answers
Answer:
your answer is 5.45 that is your answer
The number of 9 bright fringes is seen in the central maximum that spans the distance between the first missing order is 5 on one side and the first missing order on the other side
What are Arithmetic operations?Arithmetic operations can also be specified by subtracting, dividing, and multiplying built-in functions.
Blue laser light with a wavelength of 450 nm illuminates two 50-m-wide slits positioned 0.25 mm apart. On a screen 2.0 m behind the slits, the interference pattern is visible.
For dark fringe, the equation as:
yp = p λ L / d
for p =1
yp = λ× L/a
For bright fringe, the equation as:
ym = m λL / d
from (i) and (ii)
For missing order, the equation as:
ym = yp
m λL / d = λ× L/a
m=d/a
m = 0.25×10⁻³/ (50×10⁻⁶)
m=5
The number of bright fringes, the equation as:
N-1=2(m-1)
N-1 = 2×4
N = 8 + 1
N=9

Solve for the value of r.
Answers
Answer:
r=14
Step-by-step explanation:
7r+6=8r-8
14=r
r=14
Answer:
r = 14
Step-by-step explanation:
Since both angles are equivalent to each other solve for r:
7r + 6 = 8r - 8 (subtract 6 from -8)
7r = 8r - 14 (subtract 8r from 7r)
-r = -14 (divide each side by -1)
r = 14
Then plug the value of r (14) back into both parentheses:
7 * 14 + 6 = 104°
8 * 14 - 8 = 104°
The final answer is r = 14, and both angles equal to 104°

The 90% confidence interval would be given by (63.330;81.070)
Step-by-step explanation:
A confidence interval is "a range of values that’s likely to include a population value with a certain degree of confidence. It is often expressed a % whereby a population means lies between an upper and lower interval".
The margin of error is the range of values below and above the sample statistic in a confidence interval.
Normal distribution, is a "probability distribution that is symmetric about the mean, showing that data near the mean are more frequent in occurrence than data far from the mean".
Let put some notation
x=left arm , y = right arm
x: 175 169 182 146 144
y: 102 101 94 79 79
Since the Confidence is 0.90 or 90%, the value of a = 0.1 and a/2= 0.05we can use excel, a calculator or a table to find the critical value. The excel command would be: "=-T.INV(0.05,4)".And we see that ta/2= 2.13

Which shows the zeros of f(x) = x^2 – x – 2?
A. –1 and –2
B. 1 and –2
C. 1 and 2
D. 2 and –1
Answers
Explanation: To find the zeros of this quadratic function, we can factor or use the quadratic formula.
FACTORING: We need to find 2 numbers that add up to -1 (the coefficient for -x in this function) and multiply to -2 (the constant in this function). -2+1 = -1 and -2•1 = -2. Therefore x^2-x-2 can be factored into f(x)=(x-2)(x+1). To find the zeros, set each factor to zero (x-2=0 and x+1=0) and solve for x. You get 2 and -1.
QUADRATIC FORMULA: The coefficient in x^2 is 1 (a in the quadratic formula), the coefficient of -x is -1 (b in the quadratic formula), and -2 is c in the quadratic formula. Plug all of this into the formula and you get the following: -(-1) plus or minus the square root of (-1)^2 - 4(1)(-2) all over 2(1). Simplify this and you get 1 plus or minus the square root of 9 all over 2. (1+3)/2 is your first zero, 2. (1-3)/2 is your second zero, -1.

By using x-method we got that factorization [tex]x^2-25[/tex] is (x+5)(x-5)
What is factorization ?factorization is writing a expression as a product of several factors.
So Given polynomial is
[tex]x^2-25[/tex]
Now we will factorise this using x method
Here a=1 b=0 and c= -25
so ac=-25
Now We will write -25 at the top.
and 0 at the bottom.
No we will find two numbers that multiply to the top number -25 and add to the bottom number 0. Hence those numbers are -5 and 5.
Now we can write equation as
[tex]x^2-5x+5x-25\\\\x(x-5)+5(x-5)\\\\(x+5)(x-5)[/tex]
By using x-method we got that factorization [tex]x^2-25[/tex] is (x+5)(x-5)
