The distance between the points (–3,k) and (2, 0) exists k = ± 3.
How to estimate the distance between points (–3, k) and (2, 0)?
To calculate the distance between two points exists equal to
[tex]$d=\sqrt{(y 2-y 1)^{2}+(x 2-x 1)^{2}}$[/tex]
we have (-3, k) and (2, 0)
[tex]$&d=\sqrt{34}[/tex]
substitute, the values in the above equation, and we get
[tex]$\sqrt{34} &=\sqrt{(0-k)^{2}+(2+3)^{2}} \\[/tex]
simplifying the above equation
[tex]$\sqrt{34} &=\sqrt{(-k)^{2}+(5)^{2}} \\[/tex]
[tex]$\sqrt{34} &=\sqrt{k^{2}+25}[/tex]
squared both sides
[tex]$&34=k^{2}+25 \\[/tex]

Use the binomial series to find the maclaurin series for the function. f(x) = 4 1 x
Answer:
We note that,
x/³√(1+x²) dx = (3/4) d/dx (1+x²)²ᐟ³
now we can use binomial series on (1+x²)²ᐟ³
(1+x²)²ᐟ³ = ( 1+2x²/3+((2/3)*(2/3 -1)/2) x⁴ + ((2/3)*(2/3 -1)(2/3–2)/6) x⁶ +o(x⁶) =
= 1 + 2x²/3 - x⁴/9 +4x⁶/81 +o(x⁶)
The last step is to differentiate,
x/³√(1+x²) dx = (3/4) d/dx (1+x²)²ᐟ³
= (3/4) d/dx (1 + 2x²/3 - x⁴/9 +4x⁶/81 +o(x⁶) )
= (3/4) ( 0 + (4/3)x - 4/9 x³ + 24x⁵/81 + o(x⁵))
= x - x³/3 + 2x⁵/9 + o(x⁵)

Find the smallest evan number that contains every digit once
Answer:
The smallest even number that contains every digit once is 1023456798.============================
Conditions we need to meet:
Use every digit once,Even number,Smallest possible number.To get the smallest number we'd use all 10 digits in the ascending order:
0123456789Here we can't have zero in the beginning as the number becomes 9-digit.
So swapping zero with the closest digit, 1.
Our number should be even, so we should swap 9 with one even digit.
Again it should be the closest one to 9, so it is 8.
We get the following number as a result:
1023456798To test you may swap digits, any number you get will be greater than this number.

How to identify the indicated sum for the geometric series?The series is given as:
162 − 54 + 18 − 6 + .....
Start by calculating the common ratio of the geometric series.
This is calculated using
r = -54/162
Evaluate
r = -1/3
The indicated sum for the geometric series is then calculated as:
S = a(1 - r^n)/1 - r
Substitute the known values in the above equation
S = 162(1 - (-1/3)^7)/1 + 1/3
Evaluate the exponent and the sum
S = 162(1 + 1/2187)/4/3
Evaluate the sum
S = 162(2188/2187)/4/3
Express as products
S = 162 * (2188/2187)* 3/4
Evaluate the product
S = 162 * 547/729

In which:
m is the slope, which is the rate of change, that is, by how much y changes when x changes by 1.b is the y-intercept, which is the value of y when x = 0, and can also be interpreted as the initial value of the function.Considering the flat cost as the y-intercept and the cost per gigabyte as the slope, the cost of using g gigabytes is:
C(g) = 4g + 69.

[tex]3x - 2 > 10[/tex]
⇒ [tex]3x - 2 + 2 > 10 + 2[/tex] [Add 2 to both sides]

Let a_n be the integer obtained by writing all the integers from 1 to n from left to right. For example, a_3 = 123 and a_{11} = 1234567891011. Compute the remainder when a_44 is divided by 45.
Answer:
9
Step-by-step explanation:
The 79-digit number of interest can be formulated as a sum of shorter numbers whose remainders can be computed.
Expanded formThe expanded form of the number can be written as ...
a_44 = 01×10^78 +23×10^76 +45×10^74 +67×10^72 +89×10^70 +...
+10×10^68 +11×10^66 +... +43×10^2 +44×10^0
Powers of 10Each number except the last is multiplied by a power of 10. Powers of 10 modulo 45 are ...
10 mod 45 = 10
100 mod 45 = 10
This lets us conclude that any positive power of 10 mod 45 is 10.
Parts of the sumIn short, all of the multiplication by powers of 10 can be collapsed to a single multiplication by 10. Hence, the mod 45 value of a_44 will be ...
a_44 mod 45 = (((01 +23 +45 +67 +89) +10 +11 +12 +... +43)×10 +44) mod 45
= (((01 +23 +45 +67 +89) mod 45 + sum(10 .. 43) mod 45)×10 +44) mod 45
= (((225 mod 45) +(901 mod 45))×10 +44) mod 45
= ((0 +1)×10 +44) mod 45
Final valuea_44 mod 45 = 54 mod 45 = 9

What is the slope of a line that is parallel to the line whose equation is y=45x−3?
The slope is (B) -5/4.
What is a slope?The slope is the inclination of a line relative to the horizontal as a numerical value. The slope of any line, ray, or line segment in analytic geometry is the ratio of the vertical to the horizontal distance between any two points on it ("slope equals rise over run").To find the slope:
We're going to assume that we don't mean, y = 45x -3; which has a perpendicular line with a slope of -1/45.Rather, we're going to assume that we mean, y = 4/5x -3; so that the slope of the perpendicular line is -5/4.Similarly, we're going to assume that the answer choices are supposed to represent fractions so that the above slope matches choice B.If the slope of a line is m, the slope of the perpendicular line is -1/m.The reciprocal of a fraction is the fraction that has the numerator and denominator swapped, -1/(4/5) = -5/4.Therefore, the slope is (B) -5/4.

[tex]y = -\frac{2}{3}x + 490[/tex]
gradient = = [tex]-\frac{2}{3}[/tex]
y-intercept = [tex]490[/tex]
Step-by-step explanation:
• The slope-intercept form of an equation takes the general form:
[tex]\boxed{y = mx + c}[/tex],
where:
m = slope,
c = y-intercept.
• We are given the equation:
[tex]2x + 3y = 1470[/tex]
To change this into the slope-intercept form, we must make y the subject:
[tex]3y = -2x + 1470[/tex] [subtract [tex]2x[/tex] from both sides]
⇒ [tex]y = -\frac{2}{3}x + \frac{1479}{3}[/tex] [divide both sides by 3]
⇒ [tex]y = -\frac{2}{3}x + 490[/tex]
• Comparing this equation with the general form equation, we see that:
m = [tex]-\frac{2}{3}[/tex]
c = [tex]490[/tex].
This means that the gradient is [tex]\bf -\frac{2}{3}[/tex], and the y-intercept is [tex]\bf 490[/tex].

58 = 9 = b²
b² = 58 - 9
b² = 49
b = √49
b = 7
Line MD = 7
Now, we can find the area of the kite.
Diagonal p = BC = 6
Diagonal q = AD = AM + MD = 4 + 7 = 11
Area = pq/2
Area = [ 6 × 11 ]/2
Area = 66 / 2
Area = 33cm²
Given the length of the two diagonals of the kite, the area of kite ABDC is 33 squared centimeters.

Determine whether the series is convergent or divergent. 1 1 2 2 1 3 3 1 4 4 1 5 5 ⋯
Step-by-step explanation:
clearly divergent.
the elements of the series are getting bigger and bigger intercepted by some constant "1" (but they don't help here - after every intercepting "1" are 2 numbers that are larger by 1 than the 2 numbers before the intercepting "1", and that continues into infinity, so, the numbers will go to infinity, and that shows that the series is divergent).
A whole number is 6 more than 2 times another number. The sum of the two numbers is less than 50. This can be written in an inequality as x + 2x + 6 < 50, where x represents the smaller number.
The smaller number that we can take is x = 14, and in that case, the value of the other number is y = 34
How to write the inequality?First, we have two numbers, x and y, such that:
y = 6 + 2*x
"the first number is 6 more than 2 times another number".
Now we know that the sum of these two numbers is smaller than 50, then we can write:
x + y < 50
Replacing y by the above equation we get:
x + 6 + 2x < 50
3x + 6 < 50
Now we can solve that inequality for x:
3x < 50 - 6 = 44
x < 44/3 = 14.6
And x can only be a whole number, then:
x ≤ 14
The smaller number that we can take is x = 14, and in that case, the value of the other number is:
y = 6 + 2*14 = 34

The length of a rectangle is a inches. Its width is 5 inches less then the length. Find the area and perimeter of the rectangle
Answer:
Area = (a² -5a) in²
Perimeter = (4a -10) in
Step-by-step explanation:
Let the length of the rectangle be a.
Given that, its width is 5 in less than the length.
So,
length ⇒ a
width ⇒ (a - 5)
First, let's find the area of the rectangle.
Area = length × width
Area = a ( a - 5 )
Solve the brackets.
Area = (a² -5a) in²
Now, let us find the perimeter of the rectangle.
Perimeter = 2 ( l + w )
Perimeter = 2 ( a + a - 5 )
Perimeter = 2 ( 2a - 5 )
Perimeter = (4a -10) in
