The equation for the distance in kilometers to Proxima Centauri is
D = 3.99 x 10¹³
What is an Equation?
Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.
It demonstrates the equality of the relationship between the expressions printed on the left and right sides.
Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.
Given data ,
The total distance from Earth to the closest star Proxima Centauri be = D
Now , the value of distance D = 39,900,000,000,000
Now , the equation to find the scientific notation is done by calculating the number of zeros in the equation
So , The distance D has 11 zeros in it
So , the distance D can be written as powers of 10 in the form
Distance D = 399 x 10¹¹
Now , 399 can be written as 3.99 x 10²
So , the equation can be simplified as
Distance D = 3.99 x 10² x 10¹¹
Distance D = 3.99 x 10¹¹⁺²
Distance D = 3.99 x 10¹³
Therefore , the value of D is 3.99 x 10¹³
Hence , The distance in kilometers to Proxima Centauri is 3.99 x 10¹³

A security camera is set to record the activities in a 115 degrees sector of a parking lot as represented by the shaded region of the circle below. Which measurements is closet to the area of The parking lot recorders by this security camera?
Answer:35 degrees i think
Step-by-step explanation:
The area covered by security camera is 5642.18 square feet.
What is Area of sector?The region inside the portion of the circle formed by two radii and an arc is known as the area of a sector. It only covers a small portion of the entire circle's surface.
Area of sector = [tex]\theta[/tex] / 360 πR²
Given:
R= 150 /2 = 75 feet
Now, Area of sector = [tex]\theta[/tex] / 360 πR²
= 115 / 360 x 3.14 x 75 x 75
= 135412.5/24
= 5642.18 square feet
Hence, the area covered by security camera is 5642.18 square feet.

PLEASE ANSWER ASAP. What is the diagonal length of a photo frame with dimensions that are 24 cm x 7 cm?
A. 19 cm
B. 25 cm
C. 28 cm
D. 32 cm
Answer:
B
Step-by-step explanation:
The diagonal will become the hypotenuse of a right triangle, with the legs being 24 and 7.
Since it is a right triangle, we can use Pythagorean theorem
a^2+b^2=c^2
We know the legs: a and b, are 24 and 7, so we can substitute them in
24^2+7^2=c^2
Solve the exponents
576+49=c^2
Add
625=c^2
Take the square root of both sides
[tex]\sqrt{625}[/tex]=[tex]\sqrt{c^{2} }[/tex]
c=25
So, the diagonal will be 25 cm, or choice B
Answer:
25cm or b

What is the value of x?
Answer:
Step-by-step explanation:
a triangle = 180
Q = 180 - (90 + 45)
Q = 180 - 135
Q = 45
Step-by-step explanation:
With reference angle 60°
perpendicular (p) = 2√3
hypotenuse (h) = ?
We know
sin 60° = p/h
√3/2 = 2√3 / h
cross multiply
h =( 2√3 * 2)/ √3
therefore h = 4
So
Now
with reference angle 45°
perpendicular (p) = x
base (b) = 4
Now
tan 45° = p/b
1 = x / 4
Therefore x = 4

Which better describes the data set, the mean or the median? Select the answer with the best explanation. A The median, because it is in the middle of the set. B The mean, because it is closer to most of the data values than the median is. C The mean, because it is the average of all the values of the set. D The median, because it is closer to most of the data values than the mean is.
Answer:
C
Step-by-step explanation:
The mean of the data describes the data set , because it is the average of all the values of the set
What is Mean?The mean value in a set of numbers is the middle value, calculated by dividing the total of all the values by the number of values.
Mean = Sum of Values / Number of Values
Given data ,
Let the data set be represented as A
Now , the value of A is noted
And , the median of the data set is the middle term of the set
where the mean value in a set of numbers is the middle value, calculated by dividing the total of all the values by the number of values
So , the average values of the set determines the data values as it is a compilation of all the data values
Hence , the mean of the data describes the set

Answer:

Step-by-step explanation:
first you need to find out the total of the two separated and for one it is £12.49 but for the second it is 50% off so 50% is a half so half of £12.49 is £6.25 so you now need to add them both together to find out how much two bottles cost separate which is £18.74. now you need to have a look see which costs less this is the two together in the pack so the answer is you would rather buy the two packed one because they are cheaper

The experimental probability of rolling a number greater than 10 is [tex]17 \div 100[/tex]
The calculation is as follows;The total no of times rolling = 200
The probability of rolling 11 = 16 times

Solve for xxx. Write the smaller solution first, and the larger solution second. x^2 + 9x + 18 = 0x 2 +9x+18=0x, squared, plus, 9, x, plus, 18, equals, 0 \text{smaller }x =smaller x=start text, s, m, a, l, l, e, r, space, end text, x, equals \text{larger } x =larger x=start text, l, a, r, g, e, r, space, end text, x, equals
To solve the quadratic equation x^2 + 9x + 18 = 0, you'll have to find values of x that satisfy this equation.
To find the roots of the quadratic equation, we use the formula x = [-b±sqrt(b^2 -4ac)]/2a, where a, b, c are the coefficients of the quadratic equation of the form: ax^2 + bx + c = 0.
In our equation, we have:
a = 1 (coefficient of x^2)
b = 9 (coefficient of x)
c = 18 (constant term)
Substituting these values in our formula, we get:
x = [-9±sqrt((9)^2 - 4*1*18)] / 2*1,
x = [-9±sqrt(81 - 72)] / 2,
x = [-9±sqrt(9)] / 2,
x = [-9±3] / 2.
From here, we get two solutions:
For the smaller solution, we have: x = [-9 - 3] / 2 = -6.
For the larger solution, we have: x = [-9 + 3] / 2 = -3.
So, the solutions to the equation x^2 + 9x + 18 = 0 are x = -6 (for the smaller solution), and x = -3 (for the larger solution).

The graphed line shown below is y = negative 2 x minus 8.
On a coordinate plane, a line goes through (negative 4, 0) and (negative 2, negative 4).
Which equation, when graphed with the given equation, will form a system that has infinitely many solutions? y = negative 2 x minus 8.
y = negative (2 x + 8)
y = negative 2 (x minus 8)
y = negative 2 (x minus 4)
y = negative (negative 2 x + 8)
Answer:
A
Step-by-step explanation:
Our given equation is: y = -2x - 8
In order to have an equation with infinitely many solutions, it needs to be the same as the given equation.
Look at the answer choices:
A) y = -(2x + 8) = -2x - 8
This is the exact same equation, which means that any solutions for the given will also be solutions for this one. That means there will be infinitely many solutions.
B) y = -2(x - 8) = -2x + 16
We can tell this is definitely not the same as the given, so eliminate.
C) y = -2(x - 4) = -2x + 8
Again, this has a +8 instead of -8, so it's not the same and wrong.
D) y = -(-2x + 8) = 2x - 8
Here, we have positive 2 as the slope instead of -2, so it's not the same and wrong.
Thus, the answer is A.
Hope this helps!
The question is wich of the 4 formulas is equivalent to
y = -2x-8
only the first option is equivalent / basically the same and would therefore give out infinite intersections/solutions

Answer:
The amount deducted for Ms.Everett‘s paycheck for her health insurance premium is $307.6
Step-by-step explanation:
given information:
annual insurance = $12304
employer pay annually = 70%
first we calculate the annual insurance paid by the employer
employer paid annual insurance = 70% x $12304
= $8612.8
then, we calculate the insurance paid by Ms. Everett annually
Ms. Everett paid annual insurance = $12304 - $8612.8
